Patent

CA 2296208

A secure internet telecommunications system for transmitting, data has a security module which is positioned between a first computer and a a network. The security module has a cryptographic logic device that encrypts and decrypts data transmitted from the first computer in accordance with known standard encrypting and decrypting protocols. The security module is actuated by the insertion of a cryptographic token bearing a user's cryptographic key information and/or other user information. This token is first enabled to make this information available to the security module. The cryptographic token is preferably a PC card, an IC card or a Smart Card having a contact sensitive graphical user interface. The token captures through the interface a template associated with a user's ideogram signature information and stores this template and other information in memory. The template is then compared with subsequent inputs of this ideogram signature information from the user and verified to enable the cryptographic token to function with the security module. The cryptographic token may have either an independent power source permitting the token to be enabled off line from the security module or alternatively relies on the power supply of the security module. The present invention has advantage in that user information is stored on a token device which must be enabled by a user and temporarily connected with the security module to permit the use of the user information.
