Abstract

The invention provides a method and system for exchanging data between devices. In one embodiment, the invention includes a system for obtaining biometric data from a user; a system for using the biometric data as a secure key for encrypting and decrypting data; a system for transferring the secure key from a first device in contact with the user to a second device in contact with the user; and exchanging data between the first device and the second device, wherein the biometric data include biometric data from more than one source.

Claims

1. A method for exchanging data between devices, the method comprising:

obtaining biometric data from a user'"'"'s body;

using the biometric data as a secure key for encrypting and decrypting data;

transferring the secure key from a first device held by the user to a second device held by the user; and

exchanging data between the first device and the second device.

2. The method of claim 1, wherein the biometric data include biometric data from more than one source.

3. The method of claim 1, wherein obtaining includes obtaining biometric data using a device other than the first device and the second device.

4. The method of claim 1, exchanging includes exchanging data by wireless transmission.

5. A system for exchanging data between devices, the system comprising:

a system for obtaining biometric data from a user;

a system for using the biometric data as a secure key for encrypting and decrypting data;

a system for transferring the secure key from a first device in contact with the user to a second device in contact with the user; and

exchanging data between the first device and the second device.

6. The system of claim 5, wherein the biometric data include biometric data from more than one source.
