Abstract
Methods and systems are provided for generating a party static token to be used in combination with a party dynamic token for identifying a party to a host system. Identification information that identifies the party to the host system is received. Such identification information includes a host dynamic token and a host static token. A false host dynamic token that differs from the host dynamic token is generated. The host dynamic token and the false host dynamic token are encrypted. In addition, information that uniquely identifies the party dynamic token is encrypted. The party static token is produced from a combination of the encrypted host dynamic token, the encrypted false host dynamic token, and the encrypted information that uniquely identifies the party dynamic token.
