Solution Overview

Problem

Existing methods for determining the origin of typed content, especially in the presence of artificially generated content, lack accuracy and are inadequate as generative AI becomes more sophisticated, making it difficult to verify the authenticity and authorship of content.

Innovation Solution

Implementing a computer-implemented method that uses a peripheral input device with a security module to generate a digest for input data, signed with a private key and public certificate, allowing verification of the content's origin through a signing certificate and digest check.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If text analysis methods are used to determine whether content was authored by AI, then verification can be performed, but the accuracy is limited and cannot keep pace with sophisticated generative AI

Engineering Contradiction:
Improvecontent origin verification accuracyVSAvoidverification reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent applies preliminary action by signing the input data at the source (peripheral device) before it enters the system. A digest is created and signed with a private key, producing a signature that travels with the data. This pre-verification mechanism ensures authenticity is established upfront, eliminating the need for less reliable post-hoc text analysis to determine AI authorship.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If digital signing is implemented at the peripheral device level, then content origin verification accuracy is enhanced, but device complexity increases

Engineering Contradiction:
Improvecontent origin verification accuracyVSAvoidperipheral device complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses a digest as an intermediary - a simplified representation of the input data that can be signed. Instead of signing the entire complex input stream, the system creates a digest (hash) of the data, signs the digest, and attaches the signature. This intermediary approach maintains verification accuracy while reducing the complexity of the signing operation at the peripheral device.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A computer-implemented method for content origin verification is provided. The computer-implemented method includes obtaining a signing certificate for a peripheral input device. The computer-implemented method further includes receiving input data from the peripheral input device and a digest associated with the input data. The computer-implemented method further includes processing the received input data as standard input. The computer-implemented method further includes verifying an origin of the standard input, in which the verifying includes applying the signing certificate for the peripheral input device to the digest and checking contents of the digest against the standard input.
