A method for facilitating an authentication related to an electronic transaction between a first and a second user is provided. Authentication data is received from the first user along with transaction data defining the first user and the electronic transaction to be authenticated. This authentication data is compared to enrollment authentication data associated with the first user in order to verify the identity of the first user. When the user is properly verified, access to at least one private cryptographic key stored on a secure server is available for use in securing the electronic transaction. The particular private cryptographic key need not be released from the secure server. Data indicating the status of the authentication may then be sent to one of either the first or second user.

Electronic commerce with cryptographic authentication

The invention is a secure server, or trust engine, having server-centric keys, or in other words, storing cryptographic keys and user authentication data on a server. Users access cryptographic functionality through network access to the trust engine; however, the trust engine does not release actual cryptographic keys or other authentication data. Therefore, the system provides that the keys and data remain secure. The server-centric storage of keys and authentication data provides for user-independent security, portability, availability, and straightforwardness, along with a wide variety of implementation possibilities.
