               Registration Statements on Form S-8, as amended
(Registration Statements No. 333-139672, 333-137808, 333-137004, 333-120156,

Ladies and Gentlemen:

            We have acted as counsel to L-1 Identity Solutions, Inc., a Delaware
corporation (the "Company"), in connection with the preparation and filing with
the Securities and Exchange Commission (the "Commission") of the Company's
Post-Effective Amendment (the "Post-Effective Amendment") to the
above-referenced registration statements on Form S-8 originally filed by L-1
Identity Operating Company (formerly named L-1 Identity Solutions, Inc.) (the
"Predecessor Registrant").

            The Company became the successor to the Predecessor Registrant on
May 16, 2007 as a result of a merger (the "Merger"), of L-1 Merger Co., a
Delaware corporation and wholly-owned subsidiary of the Company, with and into
the Predecessor Registrant, with the Predecessor Registrant being the surviving
corporation. The Merger was consummated in accordance with Section 251(g) of the
Delaware General Corporation Law ("DGCL"). In the Merger, each share of the
issued and outstanding common stock of the Predecessor Registrant was converted
into one share of common stock of the Company, which changed its name to L-1
Identity Solutions, Inc. Pursuant to the Merger, the Predecessor Registrant
became a direct, wholly-owned subsidiary of the, Company and, each stockholder
of the Predecessor Registrant became a holder of Company common stock, $0.001
par value per share (the "Common Stock"), evidencing the same proportional
interests in the Company and having the same designations, rights, powers and
preferences and qualifications, limitations and restrictions as those securities
that such stockholder held in the Predecessor Registrant.

            The above-referenced registration statements, as amended by the
Post-Effective Amendment (the "Registration Statements"), relate to (i) the
issuance of up to 1,899,272 shares of Common Stock available for issuance under
the Identix Incorporated 2002 Equity Incentive Plan (Registration Statement No.
333-139672), (ii) the issuance of up to (1) 16,000 shares of Common Stock
available for issuance under the Viisage Technology, Inc. 1996 Directors Stock

Statement No. 333-137808), (iii) the issuance of up to (1) 776,200 shares of
Common Stock available for issuance under the Viisage Technology, Inc. 2006
Employee Stock Purchase Plan and the L-1 Identity Solutions, Inc. 2005 Long-Term
Incentive Plan, as amended (formerly named the Viisage Technology, Inc. 2005

made such inquiries of such officers and representatives, as we have deemed
relevant and necessary as a basis for the opinion hereinafter set forth.

            In connection with this opinion, we have assumed that (i) all
information contained in all documents reviewed by us is true and correct; (ii)
all signatures on all documents examined by us are genuine; (iii) all documents
submitted to us as originals are authentic and all documents submitted to us as
copies conform to the originals of those documents; (iv) each natural person
signing any document reviewed by us had the legal capacity to do so; (v) each
person signing in a representative capacity any document reviewed by us had
authority to sign in such capacity; (vi) the Registration Statements, and any
amendments thereto (including any post-effective amendments) relating to the

suspending the effectiveness of the Registration Statements has been issued and
no proceedings for that purpose are pending before or contemplated by the
Commission; (vii) the Shares have been or will be issued and sold in compliance
with applicable federal and state securities laws and in the manner stated in

authorized shares of Common Stock, less the number of such authorized shares
outstanding or otherwise reserved for issuance.

            Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that the Shares being registered for sale pursuant

delivered upon the exercise of awards and receipt by the Company of
consideration constituting lawful consideration under Delaware law and in
accordance with the terms of the applicable Plans, will be validly issued, fully
paid and non-assessable.

            The opinion expressed herein is limited to the corporate laws of the

covered by this letter of the laws of any other jurisdiction.

            We hereby consent to the use of this letter as an exhibit to the
Post-Effective Amendment.
