Data Certification via Self-Contained Proof Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data certification systems cannot verify the authenticity of printed or copied documents without using a device that issues proof information, limiting their effectiveness in ensuring non-falsification.
Innovation Solution
A data certification system comprising a server device that generates proof information including certification and time information, and a client device that acquires and uses this information to create report data, allowing verification without relying on the device that issued the proof information, with a publishing server that transmits data to devices capable of verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device that issues proof information is used to verify authenticity, then verification accuracy is improved, but system complexity and dependency increase
Solution Approach 1:
The patent creates a copy of the verification capability by embedding all necessary proof information (certification information, time information, publishing destination information) directly into the report data. This allows any device to verify authenticity without needing the original proof information issuing device, resolving the contradiction between verification accuracy and system dependency.
Solution Approach 2:
The patent segments the verification process into self-contained report data units that include all necessary verification elements. Each report data package is independently verifiable without requiring external proof information devices, thus reducing system complexity while maintaining verification reliability.
2Adaptability or versatility
If proof information is generated and transmitted to multiple destinations, then verification capability is improved, but data transmission complexity increases
Solution Approach 1:
The patent merges the proof information, report data, and publishing destination information into a single integrated data structure. This consolidation allows the same data package to be transmitted to multiple destinations without increasing complexity, as the entire verification suite travels together as one unit.
Solution Approach 2:
The report data structure is designed to be universal and self-sufficient, containing all necessary elements for verification regardless of the destination device. This multi-functional design enables the same data package to serve multiple purposes and reach multiple destinations without requiring separate proof information transmissions.
Data Source
AI summary
A data certification system includes a proof information generation unit that generates certification information for certifying non-falsification of raw data, and generates proof information including the certification information and time information representing the time of the generation of the certification information. A server transmission unit transmits the proof information which is received by a client reception unit. A time information acquisition unit acquires the time information representing the time of the generation of the certification information from the proof information. A report generation unit generates report data in which the time information and publishing destination information representing a publishing destination are included in the raw data. A transfer unit transfers the raw data, the proof information, and the report data to a publishing server which releases the report data. An output unit outputs the report data.
