Revision-Specific Electronic Signatures for Document Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for electronically stored documents do not allow for the application of electronic signatures to specific revisions, preventing changes or revisions after an initial signature is applied, which limits collaboration and document management in networked or cloud environments.
Innovation Solution
The implementation of revision-specific electronic signatures, where each revision of a document can be independently signed, allowing changes and maintaining signature effectiveness only for the applicable revision, with visual indicators for clarity and security features like expiration periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic signature is applied to an electronically stored document, then the document integrity and authentication are verified, but the document cannot be revised or changed after the initial signature
Solution Approach 1:
The patent divides the electronic signature into revision-specific components, where each signature is associated with a specific revision number. This allows the signature to be segmented from the document content, enabling the document to be revised while maintaining the integrity of previous signatures through their association with specific revisions.
Solution Approach 2:
The patent introduces dynamic revision tracking where the document can transition between revisions and signatures are dynamically associated with specific revisions. The system allows the document to evolve through multiple revisions while maintaining a history of approved signatures, making the system adaptable to changes without compromising past validations.
2Adaptability or versatility
If multiple revisions are allowed after an initial electronic signature, then document collaboration and updates are enabled, but the signature effectiveness becomes ambiguous and security is compromised
Solution Approach 1:
The patent applies local quality by making each electronic signature specific to a particular revision of the document. Each signature has localized validity to its associated revision, clearly defining which version of the document the signature validates. This eliminates ambiguity about signature effectiveness by tying each signature to a specific document state.
Solution Approach 2:
The system incorporates feedback mechanisms that track which revisions have been signed and provide information about signature validity. The system can indicate to users which revisions are signed and which are not, providing feedback that maintains security and clarity throughout the revision process.
3Productivity
If revision-specific electronic signatures are implemented, then collaboration efficiency is improved and redundant reviews are reduced, but the system complexity increases
Solution Approach 1:
The patent implements a universal signature management system that handles multiple functions: tracking revisions, validating signatures, determining signature effectiveness, and providing audit trails. By consolidating these functions into a single system framework, the patent reduces overall system complexity while improving collaboration efficiency.
Solution Approach 2:
The system performs self-service by automatically tracking which revisions are signed and determining signature effectiveness without requiring manual verification. The system maintains its own record of document revisions and signatures, reducing the need for complex manual review processes and improving collaboration efficiency.
