Recoverable biometric identity system and method

Abstract

A method for identifying persons based on biometric data achieves enhanced security and increased accuracy compared with other systems by distorting one or more biometrics prior to detection and recognition. The method includes detecting a distorted biometric for input into an identification system, comparing the distorted biometric to one or more distortion patterns, and determining an identity of the person based on results of the comparison. The biometric may be an eye pattern, a fingerprint or palm print, a voice print, a handwriting sample, a DNA sample, a facial image, or any other type of characteristic or behavioral attribute of a person. The biometric may be distorted in any one of a variety of ways for comparison to previously enrolled biometrics which have been distorted using the same or similar element. A system and program embodied within a computer-readable medium performs the steps of the method.

AI Technical Summary

Benefits of technology

[0011] An object of the present invention is to provide an improved system and method for identifying persons using biometric information.

[0012] Another object of the present invention is to provide a system and method for identifying persons using biometric information which is more secure than existing systems and methods.

[0013] Another object of the present invention is to provide a system and method of the aforementioned type which demonstrates a greater resilience to fraudulent attack from unauthorized personnel.

Problems solved by technology

While existing biometric systems have proven effective, they are not without drawbacks.

Perhaps most significantly, these systems can be breached using stolen biometric data.

Unable to determine the source of the fingerprint, the system will grant access to the thief to thereby causing a breach.

Existing biometric systems have also proven to be inaccurate because they are one-dimensional in nature, e.g., they perform identification verification based on only form of biometric data.
