Title: Bruce W. Evans: Innovator in Data Encoding and Identity Verification
Introduction
Bruce W. Evans is a notable inventor based in Redondo Beach, CA (US). He holds a total of 6 patents that showcase his contributions to the fields of data encoding and identity verification. His innovative approaches have led to significant advancements in technology.
Latest Patents
Among his latest patents is a method and apparatus for code modulation using narrow spectral notching. This invention involves encoding and decoding data in a signal through notch depth modulation. The method encodes data into the signal and utilizes notch filters to adjust the signal according to the frequency representation of the data. The apparatus for encoding includes a digitizer to convert the signal into a digital format, while a code former provides the data to be encoded. The decoding process converts the signal into a frequency domain representation and determines the notch spectral content at selected frequencies. The method establishes notch thresholds at these frequencies and decodes the data by comparing the spectral content to the thresholds.
Another significant patent is a remote identity verification technique using a personal identification device. This invention provides an apparatus and method for automatically verifying a person's identity when seeking access to a protected property. The handheld device includes a sensor for reading biometric data, such as a fingerprint image, and a correlator for comparing this data with a stored reference image. If a match is found, the device initiates a signal exchange over a communication network with the protective system. The device generates and encrypts a numerical value from the stored reference image, transmitting it to confirm the person's identity. For enhanced security, the individual registers this numerical value at each access point.
