Embedded Public Key Verification for Content Authorship
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of distinguishing between real and AI-generated content and verifying authorship of such content is difficult, necessitating systems and methods to authenticate content consumption and prevent spoofing or modification.
Innovation Solution
Embedding an encrypted media identifier within content using a public-private key pair, where the public key is stored in a database and the media identifier is encrypted with the private key, allowing continuous verification of authorship during playback by comparing the decrypted identifier with the stored media identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is published without encryption, then ease of operation is improved, but reliability of authorship verification deteriorates
Solution Approach 1:
The system performs preliminary encryption of the media identifier with the private key before content publication. The encrypted identifier is embedded into the content during the publishing process, so that when content is later consumed, the encrypted identifier can be extracted and decrypted to verify authorship. This preliminary action ensures that authorship verification reliability is established in advance without complicating the publication process.
2Reliability
If encrypted media identifier is embedded in content, then reliability of authorship verification is improved, but device complexity increases
Solution Approach 1:
The system introduces an intermediary public key mechanism to simplify the verification process. Instead of requiring complex decryption operations during content consumption, the publisher's public key is embedded in the content alongside the encrypted media identifier. This intermediary allows any consumer to verify authorship by decrypting the media identifier using the embedded public key, eliminating the need for complex centralized verification systems while maintaining high reliability.
3Measurement precision
If public key is stored in database, then measurement precision of authorship verification is improved, but loss of information increases
Solution Approach 1:
The system extracts the public key from centralized database storage and embeds it directly within the content itself. This extraction eliminates the need for continuous database access during verification, reducing data storage requirements and information loss. The embedded public key ensures that authorship verification can be performed offline with high precision, while the database only needs to store the original unencrypted media identifier for initial publishing, significantly reducing overall data storage needs.

AI summary
A method may include retrieving a media identifier for an item of content to be published, publishing a public key associated with the item of content to a database in order to store the public key in an entry associated with the media identifier, encrypting the media identifier with a private key of a public-private key pair including the public key to generate an encrypted media identifier, and during creation of the item of content, embedding the encrypted media identifier in the item of content.
