Title: Innovations by Ryoichi Mori: Pioneering Digital Signal and Tamper Resistant Technologies

Introduction

Ryoichi Mori, an esteemed inventor based in Tokyo, Japan, has made significant strides in the field of digital signal processing and information security. With a remarkable portfolio of 8 patents, he has contributed innovative solutions that enhance the reliability and security of electronic systems.

Latest Patents

One of Mori's latest inventions revolves around advanced digital signal conversion techniques that enable the detection of unauthorized changes in digital signals. This invention addresses the vulnerabilities of digital data by replacing the traditional bit '0' and bit '1' with extended length binary coded signals, such as substituting bit '0' with '011' and bit '1' with '110'. The signals are recorded in a non-rewritable medium, providing an added layer of security. Notably, a bit '0' maintains the status of the recording medium, while a bit '1' triggers a change, allowing for the recognition of unauthorized data alterations if the readout indicates '111' over a three-bit basis. Additionally, Mori's invention proposes recording a header in the medium to store the status of the recorded data.

Mori also developed a tamper-resistant module designed to protect sensitive information within electronic systems. This module enhances security by preventing unauthorized access and ensures that, in the event of tampering, confidential data is swiftly erased. Featuring a pair of bonded substrates that secure the confidential data, the module employs several logical elements such as transistors that function under normal conditions. However, tampering initiates the inoperability of these detecting memory devices, thereby safeguarding the stored information.
