- 1. A method for securing an electronic document comprising attaching a biometric characteristic and the electronic document to form a biometric characteristic-document combination and encrypting the biometric characteristic-document combination.
- 13. A system for securing an electronic document comprising means for attaching a biometric characteristic and the electronic document to form a biometric characteristic-document combination and means for encrypting the biometric characteristic-document combination.
- 26. A user terminal, for example a PC or other electronic device such as a palm pilot or a mobile telephone, the user terminal comprising means for attaching a biometric characteristic and an electronic document to form a biometric characteristic-document combination and means for encrypting the biometric characteristic-document combination.
-
28. A user terminal, for example a PC or other electronic device such as a palm pilot or a mobile telephone, the user terminal including means for receiving an encrypted biometric characteristic-document combination, the combination including a biometric characteristic that is attached to an electronic document, means for decrypting the encrypted combination, thereby to expose the biometric characteristic but not the electronic document, means for comparing the exposed biometric characteristic with a stored biometric characteristic, means for decrypting the electronic document when there is a match between the stored and the exposed biometric characteristic and means for stopping the decryption process when there is no match.
-
29. A computer program, preferably on a data carrier or a computer readable medium, for securing an electronic document, the computer program comprising instructions for:
-
attaching a biometric characteristic and the electronic document to form a biometric characteristic-document combination and encrypting the biometric characteristic-document combination. - View Dependent Claims (30, 31, 32, 33, 34)
