Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	1. Description of Business and Significant Accounting Policies
	Description of Business
	Digimarc Corporation (“Digimarc” or the “Company”), an Oregon corporation, enables governments and enterprises around the world to give digital identities to media and objects that computers can sense and recognize and to which they can react. The Company’s inventions provide the means to infuse persistent digital information, perceptible only to computers and digital devices, into all forms of media content. The unique digital identifier placed in media generally persists with it regardless of the distribution path and whether it is copied, manipulated or converted to a different format, and does not affect the quality of the content or the enjoyment or other traditional uses of it. The Company’s technology permits computers and digital devices to quickly and reliably identify relevant data from vast amounts of media content.
	Interim Consolidated Financial Statements
	The Company has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2012 in preparing the accompanying interim consolidated financial statements.
	The accompanying interim consolidated financial statements have been prepared from the Company’s records without audit and, in management’s opinion, include all adjustments (consisting of only normal recurring adjustments) necessary to fairly reflect the financial condition and the results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (the “U.S.”) have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”).
	These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the SEC on February 22, 2013. The results of operations for the interim periods presented in these consolidated financial statements are not necessarily indicative of the results for the full year.
	Reclassifications
	Certain prior period amounts in the accompanying interim consolidated financial statements and notes thereto have been reclassified to conform to current period presentation. These reclassifications had no material effect on the results of operations or financial position for any period presented. The Company has historically combined license and subscription revenue on the consolidated statement of operations, but given the increase in subscription revenue in the current year, the Company is now presenting license revenue and subscription revenue separately.
	Goodwill
	The Company tests goodwill for impairment annually in June and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Such reviews assess the fair value of the Company’s assets compared to the carrying values.
	The Company operates as one reporting unit. The Company estimated the fair value of its single reporting unit using a market approach. The market approach estimates fair value in part on market capitalization plus an estimated control premium.
	In connection with the Company’s annual impairment test of goodwill as of June 30, 2013, it was concluded that there was no impairment as the estimated fair value of the Company’s reporting unit substantially exceeded the carrying value.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Credit Carryforward Exists.” ASU No 2013-11 provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carry forward exists. The amendments in this update are effective for fiscal years and interim reporting periods beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively for all unrecognized tax benefits that exist as of the effective date. Retrospective application is permitted. The Company does not expect the adoption of this standard to have a material impact on the Company’s financial condition or results of operations.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	2. Fair Value of Financial Instruments
	Accounting Standards Codification (“ASC”) 820 “Fair Value Measurements and Disclosures” (“ASC 820”) defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles in the U.S., and enhances disclosures about fair value measurements. ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:
		•		Level 1—Pricing inputs are quoted prices available in active markets for identical assets as of the reporting date.
		•		Level 2—Pricing inputs are quoted for similar assets, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes assets valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.
		•		Level 3—Pricing inputs are unobservable for the assets; that is, the inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset.
	The estimated fair values of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate their carrying values due to the short-term nature of these instruments. The Company records marketable securities at amortized cost, which approximates fair value.
	The Company’s fair value hierarchy for its cash equivalents and marketable securities as of September 30, 2013 and December 31, 2012, respectively, was as follows:
	September 30, 2013		Level 1		Level 2		Level 3		Total

	Corporate notes			—		10,100		—		10,100
	Commercial paper			—		2,614		—		2,614
	Total		$	901	$	37,167	$	—	$	38,068
	-1	Pre-refunded municipal bonds are collateralized by U.S. treasuries.
	The fair value maturities of the Company’s cash equivalents and marketable securities as of September 30, 2013 were as follows:
			Maturities by Period
			Total		Less than		1-5 years		5-10 years		More than
					1  year						10  years
	Cash equivalents and marketable securities		$	37,384	$	32,287	$	5,097	$	—	$	—
	The Company considers all highly liquid marketable securities with original maturities of 90 days or less at the date of acquisition to be cash equivalents. Cash equivalents include mostly money market funds and pre-refunded municipal bonds totaling $4,352 and $5,878 at September 30, 2013 and December 31, 2012, respectively. Cash equivalents are carried at cost or amortized cost, which approximates fair value, due to their short maturities.

Acquisition of Attributor Corporation ("Attributor")	3. Acquisition of Attributor Corporation (“Attributor”)
	The Company accounted for the acquisition of Attributor in December 2012 using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price was allocated using the information available, pending the completion of the Company’s review of the acquired tax assets and liabilities. This review was completed with the filing of the Attributor 2012 tax return in the third quarter and resulted in no changes to the purchase price allocation as disclosed in Note 4 of the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	The Company recorded a $190 liability in the preliminary purchase price allocation reflecting the estimated fair value of the contingent merger consideration on the acquisition date, which was presented in deferred rent and other long-term liabilities at December 31, 2012. At March 31, 2013, the Company determined that the estimated fair value of the contingent merger consideration was $0 based on the Company’s most recent projections and therefore reversed the liability. As of September 30, 2013, the Company continued to believe the estimated fair value of the contingent merger consideration was $0. The reversal of the $190 liability is reflected as a reduction in general and administrative expense within the consolidated statements of operations for the nine-month period ended September 30, 2013.

Revenue_Recognition

Revenue Recognition	9 Months Ended

Text Block [Abstract]
Revenue Recognition	4. Revenue Recognition
	The Company derives its revenue primarily from development services, subscriptions and licensing of its patent portfolio:
		•		Service revenue consists primarily of software development and consulting services. The majority of service revenue arrangements are structured as time and materials consulting agreements and fixed price consulting agreements.
		•		Subscription revenue includes subscriptions for products and services, is generally recurring, paid in advance and recognized over the term of the subscription.
		•		License revenue, including royalty revenue, originates primarily from licensing the Company’s technology and patents where the Company receives royalties as its income stream.
	Revenue is recognized in accordance with ASC 605 “Revenue Recognition” and ASC 985 “Software” when the following four criteria are met:
		(i)	persuasive evidence of an arrangement exists,
		(ii)	delivery has occurred,
		(iii)	the fee is fixed or determinable, and
		(iv)	collection is reasonably assured.
	Some customer arrangements encompass multiple deliverables, such as patent license, professional services, software subscriptions, and maintenance fees. For arrangements that include multiple deliverables, the Company identifies separate units of accounting at inception based on the consensus reached under ASC 605-25 “Multiple-Element Arrangements,” which provides that revenue arrangements with multiple deliverables should be divided into separate units of accounting if certain criteria are met. The consideration for the arrangement is allocated to the separate units of accounting using the relative selling price method.
	The relative selling price method allocates the consideration based on the Company’s specific assumptions rather than assumptions of a marketplace participant, and any discount in the arrangement proportionally to each deliverable on the basis of each deliverable’s selling price.
	Applicable revenue recognition criteria is considered separately for each separate unit of accounting as follows:
		•		Revenue from professional service arrangements is generally determined based on time and materials. Revenue for professional services is recognized as the services are performed. Billing for services rendered generally occurs within one month after the services are provided.
		•		Subscription revenue, which includes subscriptions for products and services, is generally paid in advance and recognized over the term of the subscription, which is generally one month to twenty-four months.
		•		License revenue is recognized when amounts owed to the Company have been earned, are fixed or determinable (within the Company’s normal 30 to 60 day payment terms), and collection is reasonably assured. If the payment terms extend beyond the normal 30 to 60 days, the fee may not be considered to be fixed or determinable, and the revenue would then be recognized when installments are due.
		•		The Company records revenue from certain license agreements upon cash receipt as a result of collectability not being reasonably assured.
		•		The Company’s standard payment terms for license arrangements are 30 to 60 days. Extended payment terms increase the likelihood the Company will grant a customer a concession, such as reduced license payments or additional rights, rather than hold firm on minimum commitments in an agreement to the point of losing a potential advocate and licensee of patented technology in the marketplace. Extended payment terms on patent license arrangements are not considered to be fixed or determinable if payments are due beyond the Company’s standard payment terms, primarily because of the risk of substantial modification present in the Company’s patent licensing business. As such, revenue on license arrangements with extended payment terms are recognized as fees become fixed or determinable.
	Deferred revenue consists of billings in advance for professional services, subscriptions and licenses for which revenue has not been earned.

	On January 30, 2012, the Company and Verance, a longtime cash basis revenue customer, settled all disputes regarding breach of contract and patent infringement claims. In connection with the resolution of these matters, Verance paid the Company $8,852 for amounts due to Digimarc through December 31, 2011 and all claims between the parties were dismissed. Revenue from this payment was recorded in the quarter ended March 31, 2012.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	6. Stock-Based Compensation
	Stock-based compensation includes expense charges for all stock-based awards to employees and directors. These awards include option grants, restricted stock awards and preferred stock.
	Stock-based compensation expense related to internal legal labor is capitalized to patent costs based on direct labor hours charged to capitalized patent costs.
	Determining Fair Value
	Preferred Stock
	The Board of Directors authorized 10,000 shares of Series A Redeemable Nonvoting Preferred stock (“Series A Preferred”) that were issued to certain executive officers at the time of formation. The Series A Preferred has no voting rights, except as required by law, and may be redeemed at the option of the Company’s Board of Directors at any time on or after June 18, 2013.
	The Series A Preferred is redeemable based on the stated fair value of $5.00 per share. The Series A Preferred has no dividend rights and no rights to the undistributed earnings of the Company.
	Stock Options
	Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option pricing model as of the date of grant (measurement date). The Company amortizes the fair value of all awards on a straight-line basis over the requisite service periods, which are generally the vesting periods.
	Expected Life. The expected life of awards granted represents the period of time that they are expected to be outstanding. The Company determines the expected life based on historical experience with similar awards, giving consideration to the contractual terms, vesting schedules and pre-vesting and post-vesting forfeitures. Stock options granted generally vest over three to four years for employee grants and one to two years for director grants, and have contractual terms of ten years.
	Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock based on historical prices over the most recent period commensurate with the expected life of the award.
	Risk-Free Interest Rate. The Company determines the risk-free interest rate using current U.S. treasury yields for bonds with a maturity commensurate with the expected life of the award.
	Expected Dividend Yield. The expected dividend yield is derived using a formula which uses the Company’s expected annual dividend rate over the expected term divided by the fair value of the Company’s common stock at the grant date.
	There were no stock options granted during the three- or nine-month periods ended September 30, 2013 and 2012.
	The Company records stock-based compensation expense for stock option awards only for those awards that are expected to vest.
	Restricted Stock
	The Compensation Committee of the Board of Directors has awarded restricted stock shares under the Company’s 2008 Stock Incentive Plan to certain employees and directors. The shares subject to the restricted stock awards generally vest over three to four years for employees and one year for directors. Specific terms of the restricted stock awards are governed by Restricted Stock Agreements between the Company and the award recipients. Restricted stock awards are treated as outstanding when granted.
	The fair value of restricted stock awarded is based on the fair market value of the Company’s common stock on the date of the grant (measurement date), and is recognized over the vesting period using the straight-line method.
	The Company records stock-based compensation expense for restricted stock awards only for those awards that are expected to vest.

Earnings Per Share [Abstract]
Earnings (Loss) Per Common Share	7. Earnings (Loss) Per Common Share
	The Company calculates basic and diluted earnings per common share in accordance with ASC 260 “Earnings Per Share,” using the two-class method because the Company’s unvested restricted stock is a participating security since these awards contain non-forfeitable rights to receive dividends. Under the two-class method, earnings are allocated to each class of common stock and participating security as if all of the net earnings for the period had been distributed.
	Basic earnings per common share excludes dilution and is calculated by dividing earnings to common shares by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing earnings to common shares by the weighted-average number of common shares, as adjusted for the potential dilutive of stock options outstanding as of the balance sheet date. The following table reconciles earnings (loss) per common share for the three- and nine-month periods ended September 30, 2013 and 2012:

	Common stock equivalents related to stock options of 228,158 are antidilutive in a net loss period and, therefore, are not included in the diluted per common share calculation for the three-month period ended September 30, 2013.
	There were 215,000 common stock equivalents related to stock options that were anti-dilutive and excluded from diluted earnings per common share calculation for the three- and nine-month period ended September 30, 2013 and 2012 because their exercise prices were higher than the average market price of the underlying common stock for the period.

Joint Venture and Related Party Transactions	11. Joint Venture and Related Party Transactions
	In March 2012, Digimarc and Nielsen decided to reduce the investments in their two joint ventures to minimal levels while assessing alternative approaches to achieving each of their goals in the emerging market opportunity of synchronized second screen television. In connection with this plan for the suspension of operations, the joint ventures accrued estimated expenses for the first quarter’s operations and severance costs for joint venture employees. Digimarc’s share of the one-time severance and suspension costs was approximately $500. Pursuant to the plan of suspending operations of the joint ventures with Nielsen, in April 2012 the Company received $104 of remaining cash from TVaura LLC (in which Digimarc holds a 51% ownership) and contributed $796 to TVaura Mobile LLC (in which Digimarc holds a 49% ownership) to fund both the first quarter’s operating expenses as well as the suspension related costs. Payment of all expenses incurred after the suspension of operations of each joint venture is unconditionally the responsibility of the majority owner, which expenses for TVaura LLC, if any, will be paid by Digimarc. As of September 30, 2013, both Digimarc and Nielsen continued to assess the market opportunities of each of the joint ventures.
	Summarized financial information for the joint ventures has not been provided as the disclosures are immaterial to the Company’s filing given the operations of the joint ventures have been suspended and the Company’s investment in each joint venture is $0 as of September 30, 2013 and December 31, 2012.

	Digimarc Corporation (“Digimarc” or the “Company”), an Oregon corporation, enables governments and enterprises around the world to give digital identities to media and objects that computers can sense and recognize and to which they can react. The Company’s inventions provide the means to infuse persistent digital information, perceptible only to computers and digital devices, into all forms of media content. The unique digital identifier placed in media generally persists with it regardless of the distribution path and whether it is copied, manipulated or converted to a different format, and does not affect the quality of the content or the enjoyment or other traditional uses of it. The Company’s technology permits computers and digital devices to quickly and reliably identify relevant data from vast amounts of media content.
Interim Consolidated Financial Statements	Interim Consolidated Financial Statements
	The Company has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2012 in preparing the accompanying interim consolidated financial statements.
	The accompanying interim consolidated financial statements have been prepared from the Company’s records without audit and, in management’s opinion, include all adjustments (consisting of only normal recurring adjustments) necessary to fairly reflect the financial condition and the results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (the “U.S.”) have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”).
	These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the SEC on February 22, 2013. The results of operations for the interim periods presented in these consolidated financial statements are not necessarily indicative of the results for the full year.
Reclassifications	Reclassifications
	Certain prior period amounts in the accompanying interim consolidated financial statements and notes thereto have been reclassified to conform to current period presentation. These reclassifications had no material effect on the results of operations or financial position for any period presented. The Company has historically combined license and subscription revenue on the consolidated statement of operations, but given the increase in subscription revenue in the current year, the Company is now presenting license revenue and subscription revenue separately.
Goodwill	Goodwill
	The Company tests goodwill for impairment annually in June and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Such reviews assess the fair value of the Company’s assets compared to the carrying values.
	The Company operates as one reporting unit. The Company estimated the fair value of its single reporting unit using a market approach. The market approach estimates fair value in part on market capitalization plus an estimated control premium.
	In connection with the Company’s annual impairment test of goodwill as of June 30, 2013, it was concluded that there was no impairment as the estimated fair value of the Company’s reporting unit substantially exceeded the carrying value.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Credit Carryforward Exists.” ASU No 2013-11 provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carry forward exists. The amendments in this update are effective for fiscal years and interim reporting periods beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively for all unrecognized tax benefits that exist as of the effective date. Retrospective application is permitted. The Company does not expect the adoption of this standard to have a material impact on the Company’s financial condition or results of operations.
Fair Value Measurements and Disclosures	Accounting Standards Codification (“ASC”) 820 “Fair Value Measurements and Disclosures” (“ASC 820”) defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles in the U.S., and enhances disclosures about fair value measurements. ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:
		•		Level 1—Pricing inputs are quoted prices available in active markets for identical assets as of the reporting date.
		•		Level 2—Pricing inputs are quoted for similar assets, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes assets valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.
		•		Level 3—Pricing inputs are unobservable for the assets; that is, the inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset.
	The estimated fair values of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate their carrying values due to the short-term nature of these instruments. The Company records marketable securities at amortized cost, which approximates fair value.
	The Company’s fair value hierarchy for its cash equivalents and marketable securities as of September 30, 2013 and December 31, 2012, respectively, was as follows:
	September 30, 2013		Level 1		Level 2		Level 3		Total

Revenue Recognition	Revenue is recognized in accordance with ASC 605 “Revenue Recognition” and ASC 985 “Software” when the following four criteria are met:
		(i)	persuasive evidence of an arrangement exists,
		(ii)	delivery has occurred,
		(iii)	the fee is fixed or determinable, and
		(iv)	collection is reasonably assured.
	Some customer arrangements encompass multiple deliverables, such as patent license, professional services, software subscriptions, and maintenance fees. For arrangements that include multiple deliverables, the Company identifies separate units of accounting at inception based on the consensus reached under ASC 605-25 “Multiple-Element Arrangements,” which provides that revenue arrangements with multiple deliverables should be divided into separate units of accounting if certain criteria are met. The consideration for the arrangement is allocated to the separate units of accounting using the relative selling price method.
	The relative selling price method allocates the consideration based on the Company’s specific assumptions rather than assumptions of a marketplace participant, and any discount in the arrangement proportionally to each deliverable on the basis of each deliverable’s selling price.
	Applicable revenue recognition criteria is considered separately for each separate unit of accounting as follows:
		•		Revenue from professional service arrangements is generally determined based on time and materials. Revenue for professional services is recognized as the services are performed. Billing for services rendered generally occurs within one month after the services are provided.
		•		Subscription revenue, which includes subscriptions for products and services, is generally paid in advance and recognized over the term of the subscription, which is generally one month to twenty-four months.
		•		License revenue is recognized when amounts owed to the Company have been earned, are fixed or determinable (within the Company’s normal 30 to 60 day payment terms), and collection is reasonably assured. If the payment terms extend beyond the normal 30 to 60 days, the fee may not be considered to be fixed or determinable, and the revenue would then be recognized when installments are due.
		•		The Company records revenue from certain license agreements upon cash receipt as a result of collectability not being reasonably assured.
		•		The Company’s standard payment terms for license arrangements are 30 to 60 days. Extended payment terms increase the likelihood the Company will grant a customer a concession, such as reduced license payments or additional rights, rather than hold firm on minimum commitments in an agreement to the point of losing a potential advocate and licensee of patented technology in the marketplace. Extended payment terms on patent license arrangements are not considered to be fixed or determinable if payments are due beyond the Company’s standard payment terms, primarily because of the risk of substantial modification present in the Company’s patent licensing business. As such, revenue on license arrangements with extended payment terms are recognized as fees become fixed or determinable.
	Deferred revenue consists of billings in advance for professional services, subscriptions and licenses for which revenue has not been earned.
Earnings Per Share	The Company calculates basic and diluted earnings per common share in accordance with ASC 260 “Earnings Per Share,” using the two-class method because the Company’s unvested restricted stock is a participating security since these awards contain non-forfeitable rights to receive dividends. Under the two-class method, earnings are allocated to each class of common stock and participating security as if all of the net earnings for the period had been distributed.
Contingencies	Certain of the Company’s product license and services agreements include an indemnification provision for claims from third parties relating to the Company’s intellectual property. Such indemnification provisions are accounted for in accordance with ASC 450 “Contingencies.” To date, there have been no claims made under such indemnification provisions.
Subsequent Events	In accordance with ASC 855 “Subsequent Events,” the Company has evaluated subsequent events.
