AI Technical Summary

Benefits of technology

This technology allows users to create signs for their own copyrighted material by signing it twice with two separate public key systems: one system generates only unique signcodes based on how well they are typing them correctly (the other way). These signlets help verify if someone else has added this new version or copied versions of these materials without being detected beforehand.

Problems solved by technology

This patented technical problem addressed by this patent relates to finding ways to make sure individuals who want access their personal identification (PIN) codes get them safe from being hacked or stolen through various means like stealing money, accessing sensitive data stored inside devices without permissioning others, entering PIN numbers into machines equipped with these security measures, or even having physical attacks against those systems themselves.

Abstract

The invention discloses a method for verifying contents on the basis of digital signature codes. The method includes a signing step: signing a first digital content by the aid of a first private key to generate a first digital signature and a first signature code which correspond to the first digital content; a double-signature step: verifying the first digital signature according to the first signature code, and signing the first digital content again by the aid of a second private key according to the first signature code to generate a corresponding second digital signature and a corresponding second signature code; a verifying step: verifying at least one component of a digital signature group according to at least one component of a signature code group. The first signature code and the second signature code are connected with each other and form the signature code group, and the first digital signature and the second digital signature form the digital signature group. The method has the advantage that the authenticity of the signed digital content can be conveniently confirmed by the aid of the method.
