Secure Property Transfer Document Preparation via Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital inventory solutions for property transfer documents, such as those used in motor vehicle rentals, lack sufficient security, making the stored information falsifiable and creating legal risks due to lack of authentication and integrity.
Innovation Solution
A computer-implemented method for secure property transfer document preparation involving data acquisition, creation of an entry log, computing a final security key, and storing data and security keys, with incremental key computation and decentralized storage in a blockchain to ensure authenticity and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital inventory solutions are used to replace paper documents, then the process becomes more efficient and accessible, but the security and authenticity of the stored information deteriorates
Solution Approach 1:
The system performs preliminary actions by capturing data entry events in real-time and computing security keys before the document is finalized. The entry log records each data entry event with a timestamp, and security keys are computed incrementally as data is entered, ensuring authenticity is established before any potential tampering can occur.
Solution Approach 2:
The patent introduces security keys and entry logs as intermediary elements between the user input and the final document. These intermediaries serve as verifiable bridges that prove the document content matches the original data entries, preventing direct manipulation of the final document without detection.
2Reliability
If security keys and entry logs are computed and stored for each data entry, then the authenticity and integrity of the document is improved, but the system complexity increases
Solution Approach 1:
The security verification process is segmented into discrete, manageable components: individual security keys are computed for specific data entries, entry log records are created for each data entry event, and these segments are stored separately. This segmentation allows the complex security function to be broken down into simple, repeatable operations that can be verified independently.
Solution Approach 2:
The system creates copies of the data entry process through the entry log and security keys. Instead of securing the entire document at once, the system copies the essential authentication information (data entries, timestamps, and computed keys) into separate verifiable records, allowing the main document to remain simple while the authentication mechanism becomes robust.
3Device complexity
If data is stored in a centralized manner, then the system is simpler to implement, but the security against unauthorized modifications and data breaches deteriorates
Solution Approach 1:
The patent transitions from centralized storage to decentralized storage by distributing security keys and entry log records across multiple locations. This dimensional change from a single storage point to multiple distributed storage points eliminates single points of failure and prevents unauthorized modifications, as changes would need to occur across multiple independent storage locations simultaneously.
