Signer offers secure signing for web services, e.g. eBanking, eGovernment. It combines strong authentication with digital signatures to enable user-mobility without trading off security. A user can request a signature at any time via the internet, e.g. from a web browser or an e-mail client. With Signer, users are able to sign legally binding electronic transactions securely from anywhere in the world.
The Signer is a central server, which stores users' private keys in a secure database and generates digital signatures on their request. As the private key is stored centrally, the physical security and responsibility of the key no longer lies with the individual user, as it is not stored on a PC or hardware token. Multiple authentication methods can be used with Signer via the Authenticator.
The Signer functionality of using a central server for securely creating digital signatures on a user's behalf is a unique design by Cryptomathic and is patented worldwide.
