Digital Timestamp Device Authentication Without Third Parties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital timestamp systems rely on third-party authentication, which is complex, insecure, and prone to credibility issues due to potential time inconsistencies and reliance on trusted third parties for verifying the authenticity of digital documents.
Innovation Solution
A system and method where a digital timestamp device provides accurate instant timestamps directly to a provider end, which stamps the timestamp on digital content, records the position, and stores it with network location information, allowing the receiver end to verify authenticity without third-party intervention by confirming consistency over a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a third-party authentication service is used to verify digital timestamp authenticity, then the reliability of timestamp verification is improved, but the device complexity and operational complexity increase due to multiple authentication steps and trusted third party dependencies
Solution Approach 1:
The patent extracts the timestamp verification function from the third-party authentication service and embeds it directly into the digital timestamp device. The device independently generates and verifies timestamps using its own secure clock and cryptographic keys, eliminating the need for external authentication services and reducing system complexity while maintaining reliability
Solution Approach 2:
The digital timestamp device performs self-verification of timestamp authenticity using its internally stored cryptographic keys and synchronization data. The device autonomously ensures timestamp validity through self-contained verification mechanisms, removing dependency on third-party services and simplifying the overall authentication architecture
2Ease of operation
If machine time is provided directly by the provider end without third-party authentication, then the ease of operation is improved, but the reliability of time accuracy deteriorates due to potential machine time modification
Solution Approach 1:
The patent applies beforehand cushioning by pre-synchronizing the digital timestamp device's clock with authoritative time sources and pre-storing cryptographic verification data. This preparation ensures that even though the provider end directly provides timestamps, the reliability is maintained through advance security measures and built-in verification mechanisms that prevent time manipulation
3Adaptability or versatility
If multiple digital timestamps from several parties are used, then the versatility and adaptability of the system is improved, but the device complexity increases due to time consistency coordination among multiple parties
Solution Approach 1:
The patent implements universality by designing the digital timestamp device to perform multiple functions: time synchronization with various time sources, cryptographic key management, timestamp generation, and verification. This multi-functional design enables the device to handle multiple parties' timestamp requirements through a single unified system, avoiding the complexity of separate coordination mechanisms for each party
Data Source
AI summary
The present invention is related to an authentication system of synchronizing instant timestamp issued by a digital timestamp device and a method thereof. The digital timestamp device provides an instant machine time, and the provider end uses the digital timestamp device to stamp an instant digital timestamp on a digital content. Meanwhile, the provider end records the position of the digital content whereon the digital timestamp is stamped as a stamp position, and store the digital content, the instant digital timestamp, the stamp position, and the network location information together as a reliable digital content. The receiver end can retrieve the reliable digital content from a third party end or connect to the provider end to confirm whether the reliable digital content has the identical instant digital timestamp and stamp position to ensure the authenticity of the received reliable digital content.
