Tamper-Proof Interaction Recording via Blockchain Timestamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information security measures fail to effectively protect data files from tampering, unauthorized access, and duplication, particularly in scenarios where the security provider itself may be a threat, necessitating a solution for authenticating and timestamping files to ensure their integrity and authenticity.
Innovation Solution
A system and method utilizing a network-connected computer server with an authentication system that generates and verifies timestamps, hashes recordings of interactions (including audio, video, and SMS), encrypts them, and stores them in a secure database, leveraging distributed blockchain networks to prevent tampering and ensure file integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures are used to protect data files, then basic access control is provided, but the files remain vulnerable to tampering and unauthorized manipulation by security providers themselves
Solution Approach 1:
The patent introduces a timestamping authority as an intermediary that issues cryptographic timestamps for data files. This intermediary acts as a trusted third party that neither the security provider nor any single entity can control, thereby preventing tampering while maintaining reliability. The timestamping authority mediates between file creators and verification parties, providing independent certification of file integrity.
Solution Approach 2:
The patent applies preliminary action by embedding cryptographic timestamps into data files at the moment of creation or modification. This preliminary timestamping prevents future tampering because any alteration to the file would invalidate the embedded timestamp, making the tampering detectable. The security measure is built into the file structure beforehand rather than added later.
2Reliability
If cryptographic timestamps are embedded in data files, then tamper-proof evidence is provided, but system complexity increases due to multiple security layers
Solution Approach 1:
The patent segments the security system into distinct functional components: file creation modules, timestamping authority, verification modules, and storage systems. Each component has a specific responsibility, which simplifies the overall system architecture despite the multiple security layers. The segmentation allows independent development and verification of each module while maintaining overall system security.
3Reliability
If multiple security layers including blockchain are implemented, then tamper resistance is enhanced, but processing time and computational resources increase
Solution Approach 1:
The patent applies partial action by implementing selective verification where only critical files or suspicious files undergo full blockchain validation, while routine files use lighter verification methods. This approach maintains high tamper resistance for important data while reducing processing time for常规 operations. The system adjusts the level of security applied based on the specific needs and risk assessment of each file or operation.
