Latest Patents

Tony Feng's latest patents include "Secure computer evaluation of k-nearest neighbor models" and "Secure computer evaluation of decision trees." The first patent describes a system where a user device and server computers securely evaluate a k-nearest neighbor model. This is achieved through a combination of techniques that ensure reasonable computation speed and bandwidth utilization. The user device encrypts input vectors using a client's public key, maintaining client information privacy. The server computer then performs homomorphic computations to determine distances between encrypted input vectors and those stored in the model, ultimately providing classification vectors for the k-nearest neighbors.

The second patent outlines a method for securely evaluating decision trees. In this system, a user device encrypts input vectors using a client's public key within an additively homomorphic encryption framework. The server computer randomizes the decision tree for each evaluation, ensuring that the path indicative of the input vector's application to the decision tree varies with each use. The server computes evaluations of decision nodes and provides a value indicative of the path through the decision tree, which is accessible to both the client and the server in a secure manner.
