ABSTRACT:
The invention relates to a computer implemented method for generating a pseudonym for a user comprising entering a user-selected secret, storing the user-selected secret in memory, computing a private key by applying an embedding and randomizing function onto the secret, storing the private key in the memory, computing a public key using the private key, the public key and the private key forming an asymmetric cryptographic key, erasing the secret and the private key from the memory, and outputting the public key for providing the pseudonym.
