Latest Patents

Hengrui Jia holds a patent for the invention titled "Detection of privacy attacks on machine learning models." This patent describes a method where a plurality of queries are input into an AI model composed of multiple layers, including an input layer, an output layer, and at least one intermediate layer. During inference, each intermediate layer can output a plurality of activations. The invention intercepts activations from these intermediate layers for each query and determines if the distribution of these activations indicates attempts to manipulate the AI model. This is achieved through a distance-based similarity analysis between intercepted activations and reference activations. The results of this analysis are then provided to a consuming application or process, enhancing the security of AI systems.
