Abstract: The invention relates to a computer implemented method, a computer system and a computer program for privacy enhanced comparison of a plurality of data sets. The method comprises the steps of: - allocating a private encryption key to each of the data sets, - an encryption step being performed for each of the data sets, the encryption step comprising generating a commutatively encrypted data set of the respective data set, wherein the commutatively encrypted data sets are generated by successively applying a keyed commutative encryption function on the respective data set with the private encryption key of the respective data set itself and with the private encryption keys of the other data sets, - comparing the commutatively encrypted data sets.

Abstract: The invention relates to a method for providing an assertion message (200) from a proving party (20) to a relying party (40), the method comprising the steps of: - creating an assertion (A) comprising one or more statements, - creating an assertion proof (p A), - creating a temporary private key and a corresponding temporary public key (K) from the assertion (A) and the assertion proof (p A), - creating a key proof (PK) for the temporary public key (K), - creating an assertion message signature (S) by means of the temporary private key, - creating the assertion message (200) comprising the temporary public key (K), the assertion proof (PA), the key proof (PK), the assertion (A), a message body (220) and the assertion message signature (S) to the relying party (40).
