Authentication system using paired, role reversing personal devices

Abstract

An authentication system is provided for authenticating users in accordance with an encryption/decryption algorithm using first and second separately unique encryption keys that are time variable and are uniquely associated with each user, having a first user controlled computing device under the control of the user for generating said first encryption key using an encryption key generating algorithm. The first user controlled computing device includes a key transmitter for transmitting wirelessly within the immediate vicinity of the user the first encryption key, a second user controlled computing device, operating as a coordinating device under the control of the user, for generating the second encryption key using the encryption key generating algorithm. The second user controlled computing device includes a key receiver for receiving the first encryption key.
