Introduction

From around 450 BC, the oldest record in the history of cryptography, to the present, we humans have been using fixed-value-based cryptography. Fixed-value-based refers to fixed information such as IDs and passwords. All existing security systems are fixed-value-based, and fixed information with "cases" is highly vulnerable to hacking and theft. This is because the server cannot distinguish whether the user is the real person or someone else is stealing the information because the user is authenticated through a simple comparison and contrast procedure between the information entered by the user and the information stored on the server. TSID is the first in the world to introduce a paradigm that converts the fixed-value cryptography system that humans have used for approximately 2,500 years to a non-fixed value. Through technical verification by non-life insurance companies and reinsurance companies, we have concluded the world's first self-authentication insurance contract, and if damage occurs due to TSID self-authentication being authenticated or stolen on someone else's mobile phone, the non-life insurance company will provide coverage.
