Abstract
The invention relates to a method for enrolling data in order to verify the authenticity of a security datum, the method comprising implementing by data processing means of a server the steps of: obtaining a reference security datum, generating a first encoded datum by applying to the reference security datum an obfuscated fuzzy Hamming distance encoding procedure, determining from the reference security datum, a plurality of derived data of the reference security datum, generating a first random datum, and determining a second encoded datum such that a variable point comparison predicate parameterized by the second encoded datum and the first random datum is true when said variable point has as coordinates said derived data, storing on a data storage means of the server at least said first and second encoded data. The invention also relates to a verification method and a server for this purpose.
