Machine learning model validation and authentication

This invention describes a way to check if a machine learning model is being used legitimately or if it's been tampered with. It works by giving the model a special digital key as input. The system then looks at the model's internal processing steps, specifically the intermediate results from its hidden layers, and compares them to what it expects to see when the key is used correctly. If the internal results don't match, it indicates a problem, like unauthorized use or an attack.

Why it matters: Since 2020, the proliferation and increasing value of advanced machine learning models, especially generative AI, have significantly heightened the need for robust methods to ensure their integrity and prevent unauthorized use. This invention's focus on validating internal model states addresses these growing security challenges directly.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
