<p>The invention relates to a method for constructing a negative identity database relating to persons for the purpose of biometric verification, said negative identity database being correlated with a biometric database (10) storing groups of biometric data (b1, b2,..., bm) relating to said persons. The method includes: obtaining a respective identity datum (i1,i2, - · ·,im) relating to each of said persons; creating an association between each obtained identity datum relating to a respective person, and a pointer (p1,p2,...,pm) directed to a group stored in the biometric database that includes a biometric datum relating to said respective person; and constructing a negative identity database (12) from the set matching the set of created associations.</p> |
