  • Patent number: 6134661
    Abstract: A keyboard which performs a password encryption function, i.e., converting a memorable (insecure) password which is typed on the keyboard, into a secure password which is used to gain access to a computer network system. A preferred embodiment of the present invention comprises a user designated keyboard having an activating module and an encrypting module, both of which are disposed within the keyboard. To gain access to a computer network, the user will press an activating key of the keyboard which sends an activating signal to the activator. The activating module will direct all subsequent keystroke signals (i.e. password) to the encrypting module, which performs an encrypting function and generates an encrypted password. When the user is finished typing the password, a deactivating key is pressed, which send the encrypted password to the computer network and which signals the activating module to divert (pass through) all subsequent keystroke signals.
