Title: Yuto Hayaki: Innovator in Tamper Detection Technology

Introduction

Yuto Hayaki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of software security, particularly in tamper detection technologies. With a total of 2 patents to his name, Hayaki is recognized for his innovative approaches to enhancing software integrity.

Latest Patents

Hayaki's latest patents include a "Monitoring Range Determination Device" and a "Tamper Detection Feature Embedding Device." The monitoring range determination device is designed to receive input of the binary of the software to be monitored, which includes embedded tamper detection features. It utilizes a control flow graph (CFG) generation unit to create a CFG based on the binary, allowing for the determination of the monitoring range for tamper detection functions. The allowed list creation unit sequentially selects these functions and adds them to the monitoring range based on predetermined rules.

The tamper detection feature embedding device, on the other hand, inputs a first source code of the software to be monitored. It builds this source code to generate a binary and creates a CFG based on it. The device then embeds tamper detection features into a second source code, generating a second binary and CFG. This process culminates in the creation of an allowed list that includes hash values of the monitoring range for the tamper detection functions.

Career Highlights

Yuto Hayaki is currently employed at NEC Corporation, where he continues to develop innovative solutions in software security. His work has been instrumental in advancing the capabilities of tamper detection technologies, making software systems more secure against unauthorized modifications.
