TIMESTAMP GENERATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240259196 titled 'TIMESTAMP GENERATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

The patent application describes a method and apparatus for generating timestamps, as well as an electronic device and a storage medium, to address the issue of information leakage due to the reliance on a trusted third party in traditional timestamp generation methods.

• Acquiring a file record
• Calculating a hash value of the file record
• Sending the hash value to a random issuer and receiving a signature result
• Storing the signature result in a blockchain as a timestamp of the file record

Potential Applications: - Securely timestamping sensitive information - Ensuring data integrity in digital records - Providing proof of existence for intellectual property

Problems Solved: - Eliminating the need for a trusted third party timestamp authority - Preventing information leakage and tampering of records

Benefits: - Enhanced security and trust in timestamping process - Simplified and decentralized timestamp generation - Improved data integrity and authenticity verification

Commercial Applications: Timestamping services for legal, financial, and intellectual property industries

Questions about the technology: 1. How does the random issuer ensure the security and authenticity of the timestamp? 2. What are the potential scalability challenges of storing timestamp data in a blockchain?

Frequently Updated Research: Stay updated on advancements in blockchain technology for secure timestamping solutions.

Original Abstract Submitted

a timestamp generation method and apparatus, and an electronic device and a storage medium, which are used for solving the technical problem of recorded information being easily leaked because a trusted third party is usually needed as a timestamp authority for recording in a traditional trusted timestamp generation method. in the present invention, the method comprises: acquiring a file record; calculating a hash value of the file record; sending the hash value to a random issuer, and receiving a signature result returned by the random issuer, wherein the signature result is generated after the random issuer signs the hash value and a receiving time, and the receiving time is the time when the random issuer receives the hash value; and storing the signature result in a blockchain as a timestamp of the file record.
