  • Methods for digitally signing an electronic file and authentication method
    Patent number: 11310058
    Abstract: The invention is a method for digitally signing an electronic file (48), comprising the steps carried out by a server: generating a challenge value (50) comprising a projection parameter (52), transferring the challenge value (50) to a client device through a communications channel, receiving, through a communications channel, an evidence record (70), the electronic file (48) to be signed, and a user's biometric data (54) from the client device, generating reduced biometric verification data by applying a projection utilising the projection parameter (52), generating a verification evidence record and comparing it against the evidence record (70) sent by the client device, generating a server certificate, signing the server certificate applying the server's private signing key, thereby generating a signed server certificate, generating a digital signature by associating at least the signed server certificate and the hash (49) of the electronic file (48), and associating the digital signature with the electron
