Title: Alan Bruce Hamersley: Innovator in Optical Disc Authentication

Introduction

Alan Bruce Hamersley is a notable inventor based in Newbury Park, California. He has made significant contributions to the field of optical disc technology, holding a total of 15 patents. His work focuses on enhancing the security and authentication of data discs, which is increasingly important in today's digital landscape.

Latest Patents

One of Hamersley's latest patents is titled "Optical disc authentication by interferometric fingerprinting." This innovative method utilizes interferometric authentication data to authenticate discs. The data is generated based on an interference pattern associated with thickness variations of a material layer on the disc. This unique fingerprint can be used for the authentication of individual discs, ensuring their integrity and security.

Another significant patent is the "Method and system for disc authentication and security." This invention discloses a method and apparatus for disc authentication that includes measuring at least one physical property of a data disc. This property may include parameters such as angle and eccentricity associated with two data layers of the disc. The disc is authenticated by determining whether a match exists between the measured property and encoded information on the data layer relating to that physical property.
