Definitions
- the data of the individual or of the object, acquired by the control server is compared with the set of data of the database in order to identify whether at least one datum of the database corresponds to the datum acquired, and thus identify the individual or object as an individual or an object listed in the database.
- the generation of the public key and the private key includes:
- the invention also proposes a method for decrypting an encrypted data obtained by applying to a binary data item the encryption method described above, the decryption method comprising:
- k 0 for ⁇ k.
- This type of coding makes it possible to ensure that even a partial knowledge of the encoded data B does not make it possible to obtain the decoded data A.
- the encrypted data b obtained thus comprises m bits.
- the sum of the bits of b indexed by the elements of S j for each j between 1 and I is calculated, which corresponds to a bit y j of the encoded data y.
