摘要： 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 electronic file (48), thereby generating a digitally signed electronic file. The invention is further an authentication method.
摘要翻译：本发明是一种用于对电子文件（48）进行数字签名的方法，包括由服务器执行的以下步骤： - 生成包括投影参数（52）的质询值（50）; - 将质询值（50）客户端设备， - 通过通信信道接收证据记录（70），待签名的电子文件（48）以及来自客户端设备的用户的生物测定数据（54）， - 生成简化的生物测定验证通过利用投影参数（52）应用投影来生成数据， - 生成验证证据记录并将其与由客户端设备发送的证据记录（70）进行比较， - 生成服务器证书， - 对服务器证书应用的服务器证书进行签名从而生成签名的服务器证书， - 通过至少关联签名的服务器证书和电子文件（48）的散列（49）来生成数字签名，以及 - 将关联用电子文件（48）进行数字签名，从而生成数字签名的电子文件。本发明还是一种认证方法。

摘要： 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 electronic file (48), thereby generating a digitally signed electronic file. The invention is further an authentication method.
