Blockchain Document Integrity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integrity of digitally encoded documents, particularly in the context of news dissemination over the internet, is difficult to verify due to the ease of copying and manipulation, leading to concerns about authenticity and trustworthiness, especially with the spread of 'fake news'.
Innovation Solution
A method using a blockchain structure embedded in digitally encoded copies to log lineage histories, ensuring the integrity of the documents by adding blocks with identifiers and verification characteristics, allowing for tracing and verification of the document's origin and any changes made during copying processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digitally encoded documents are copied and disseminated over the internet, then the reach and distribution of information is improved, but the integrity and authenticity of the documents deteriorates due to ease of manipulation
Solution Approach 1:
The patent applies preliminary action by embedding a blockchain structure with verification features into the original document before dissemination. This pre-established cryptographic framework enables future integrity verification without requiring real-time intervention during copying or distribution processes.
Solution Approach 2:
The patent implements feedback through verification features that allow recipients to check document authenticity by tracing the lineage history stored in the blockchain structure. This creates a closed-loop system where integrity information flows back to users, enabling them to verify whether documents have been manipulated.
2Ease of manufacture
If traditional copying methods are used for digitally encoded documents, then the ease of replication is improved, but the ability to verify authenticity and trace lineage deteriorates
Solution Approach 1:
The patent applies the nested doll principle by embedding a blockchain structure within the document itself. The blockchain contains nested blocks with verification features and lineage information that are integrated into the document's metadata, creating a self-contained integrity verification system.
Solution Approach 2:
The patent uses the blockchain structure as an intermediary that mediates between the document content and verification requirements. Rather than requiring complex external verification systems, the blockchain acts as a self-contained intermediary layer that stores and enables verification of lineage history.
3Reliability
If blockchain structures are embedded in every copy to track lineage, then the integrity verification capability is improved, but the device complexity and data overhead increases
Solution Approach 1:
The patent applies copying by replicating the blockchain structure with verification features into each document copy. Rather than maintaining a single centralized verification system, each copy contains its own embedded blockchain, enabling independent verification without requiring access to external verification infrastructure.

AI summary
The invention relates to a method for the integrity protection of digitally coded copies (110, 120, 130, 314) of a digitally coded original document (100) by using a block chain structure (111, 121, 131, 200, 201, 229, 231, 312, 316) integrated into the copies (110, 120, 130, 314) to log the descent history of the copies (110, 120, 130, 314). The method comprises: providing a digitally coded copying template (100, 110, 120, 310), which comprises data (102) of the digitally coded original document (100) and a block chain structure (111, 121, 131, 200, 201, 229, 231, 312, 316), in which the descent history of the copying template (100, 110, 120, 310) is logged, creating a digitally coded copy (110, 120, 130, 314) of data (102) of the copying template (100, 110, 120, 310), the copied data (102) of the copy (110, 120, 130, 314) comprising the data (102) of the digitally coded original document (100) and the block chain structure (111, 121, 131, 200, 201, 229, 231, 312, 316) of the copying template (100, 110, 120, 310), adding an additional block (116, 128, 136) to the copied block chain structure (111, 121, 131, 200, 201, 229, 231, 312, 316), the additional block (116, 128, 136) being associated with the copying template (100, 110, 120, 310), the additional block (116, 128, 136) comprising an identifier (104, 114, 124, 134) of the copying template (100, 110, 120, 310) and a checking characteristic (PM) of the copied data (102), thus allowing an integrity check of the copied data (102) including the copied block chain structure (111, 121, 131, 200, 201, 229, 231, 312, 316).
