Immutable Document Sealing With Salted Hash-Linked Filenames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional document security methods, relying on password protection and encryption, are vulnerable to malicious actors who can create spoof documents by modifying duplicate documents, compromising document authenticity.
Innovation Solution
A method involving snowflaking a digital document image with non-visible elements, generating salted hash values, and combining them with the document name to create an unbreakable linkage, ensuring the document's integrity and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password protection and encryption are used to secure documents, then document security is improved, but document authenticity can still be compromised by malicious actors creating spoof documents
Solution Approach 1:
The patent applies snowflaking and generates salted hash values in advance before document transmission or storage. This preliminary processing embeds unique identifiers and cryptographic hashes into the document structure, creating an immutable fingerprint that prevents later spoofing attempts. The hash values are computed beforehand and stored alongside the document, enabling future authentication without requiring real-time computation during verification.
2Reliability
If digital certificates and multiple participants are involved in document authentication, then document security is improved, but the complexity of the authentication process increases
Solution Approach 1:
The patent extracts the essential authentication elements (snowflaked identifiers and salted hash values) from the complex multi-party digital certificate system. By isolating these core cryptographic components and embedding them directly into the document structure, the system maintains strong authentication capabilities while eliminating the need for complex multi-party verification protocols. The extracted hash values can be verified independently without requiring involvement from multiple certificate authorities or participants.
3Reliability
If conventional encryption methods are used, then document security is improved, but malicious actors can still modify duplicate documents to create spoofs
Solution Approach 1:
The patent applies snowflaking to transform the document's visual or structural appearance by embedding non-visible elements and altering the document's composition. This transformation changes the document's 'color' or characteristics in a way that creates a unique, immutable fingerprint. Any modification to the document after snowflaking will change its hash value, making tampering detectable. The snowflaked document maintains its original functionality while acquiring new identifying characteristics that prevent spoofing.

AI summary
Immutable document sealing includes loading a digital image of a document into memory of a computer and applying snowflaking to the digital image by incorporating one or more non-visible elements to the digital image. Immutable document sealing additionally includes generating a primary salted hash value based upon the snowflaked digital image to produce an additive value and combining the primary salted hash value with a selected name for the digital image in order to generate a secondary salted hash value of the combination. Finally, Immutable document sealing includes adding the secondary salted hash value to the selected name for the digital image of the document to produce a modified form of the selected name and persisting the encrypted digital image into a new file with the modified form of the selected name as a new name for the new file.
