System, Server, Terminal and Tamper Resistant Device for Authenticating a User |
摘要 |
The authentication server authenticated by a public key certificate at the time of authentication generates a difference parameter, transforms a template by the difference parameter to create a temporary registration template, and transmits the difference parameter to a tamper resistant device. The tamper resistant device generates a temporary parameter from the held transformation parameter and the difference parameter. A client terminal transforms feature using the temporary parameter, and generates temporarily-transformed feature. An authentication server receives the temporarily-transformed feature, and verifies whether the temporary registration template is in agreement with the temporarily-transformed feature.
