| Zusammenfassung: | The method involves generating a digital signature through digitisation and, optionally, compression of a plane text. The digitised, compressed text is transformed with a secret, user-specific key. For each signature generation, in addition to other data, a biometric characteristic of the user is measured.This value is reproducible and is used as an output value to derive the secret key. Neither secret key or secret output value are stored in permanent system memory. |
