Apparatus and method for securing information transmitted on computer networks
First Claim
1. A method for communicating confidential data from a sender to a receiver, comprising the steps of:
- (A) encrypting the confidential data while the confidential data is in the control of the sender, said step of encrypting including mixing the confidential data with biometric data to produce encrypted data;
(B) sending the encrypted data over a communication link to the receiver;
(C) de-encrypting the encrypted data while the encrypted data is in the control of the receiver by separating the biometric data from the confidential data.

Abstract
A method for communicating confidential data over a computer network, such as the Internet includes encrypting the confidential data while the confidential data is in the control of a sender. The step of encrypting includes mixing the confidential data with biometric data to produce encrypted data. The encrypted data is then sent over a communication link to a receiver. The encrypted data is de-encrypted while the encrypted data is in the control of the receiver by separating the biometric data from the confidential data. Voice signatures are convenient forms of biometric data and may be used for the dual purpose of encrypting the data to be sent and serving as a key to be matched by the second entity to gain access to the data, i.e., to allow de-encryption. The further step of converting the encrypted data from a first format to a second format, e.g., wave file format, may provide additional security and requires the reconversion by the second entity in order to de-encrypt. Additional key data may be generated and combined with the confidential data and/or biometric data in accordance with a predetermined algorithm to create a second level of encryption and which is de-encrypted by a reverse algorithm.

25. A method for encrypting and de-encrypting confidential data, comprising the steps of:
-
(A) Encrypting the confidential data by combining the confidential data with secret key data in accordance with a first predetermined logical/mathematical algorithm to produce data at a first level of encryption;
(B) Obtaining biometric data relating to a living creature;
(C) Mixing the biometric data with the data at the first level of encryption in accordance with a second predetermined algorithm to produce data at a second level of encryption;
(D) De-encrypting the data at the second level of encryption by separating the data at the second level of encryption with the biometric data and the data at the first level of encryption using the second pre-determined algorithm in reverse; and
(E) De-combining the confidential data and the secret key data using the reverse of the first predetermined logical/mathematical algorithm. - View Dependent Claims (26, 27, 28)
