Abstract
The invention relates to a database (10) suitable for combining biometric data (b) and an identifier (Id(b)). For this purpose, biometric data (bref) are collected (101). Next, a plurality of keywords is generated (102) by means of applying a family (H) of hash functions to the biometric data. Then, a plurality of addresses (@i) is obtained (103) by means of applying an addressing function (F) to the plurality of keywords and to a secret key. Finally, the identifier is stored (104) at said plurality of addresses.
