Anti-Tamper Optical Secure Read/Write/Erase Memory

To address the need for secure memory that can store and protect sensitive information and securely zeroize itself if tampering occurs, Physical Optics Corporation (POC) proposes to develop a new Optical Secure Read/Write/Erase Memory (OSRWEM) system based on crosslinkable liquid crystal, a tunable liquid crystal source, a CCD chip, and use of light shaping diffuser with a tunable light source, which is a mature POC technology. This marks the ODRWEM structure compact, economical, similar to a flash memory in a cell phone. This read/write/erase nonvolatile memory can securely erase stored information, and is itself secure from unauthorized reading and X-ray tampering. In addition, the memory can be permanently destroyed by application of a few volts, making reverse engineering impossible. In Phase I POC will show the feasibility of the OSRWEM system by demonstrating its features in a simplified assembled system. In Phase II POC plans to develop a prototype to show how the OSRWEM can act as nonvolatile memory that can securely clear all sensitive information, and thus protect against successful tampering.
