Latest Patents

One of Kerschbaum's latest patents is titled "System and method for secure detection of similarity and dissimilarity of events." This innovative system allows a plurality of clients to encode events as respective vectors and cooperatively choose a joint key. Each client encrypts its event vector(s) using the joint key to form secret shares of a fixed value. The encoded, encrypted vectors are then sent to a service-providing system that selects pairs of the vectors and determines a comparison value from a reconstruction of the secret shares. When the comparison value meets a predetermined criterion, the system generates a message indicating similarity between the selected pairs of vectors. This method allows for the determination of a degree of similarity between events without requiring knowledge of the raw data about the events.

Another significant patent is "Non-interactive private decision tree evaluation." This patent provides a non-interactive protocol for evaluating machine learning models, such as decision trees. A client can delegate the evaluation of a machine learning model to a server by sending an encrypted input and receiving only the encryption of the result. The inputs can be encoded using their binary representation, and efficient data representations are combined with different algorithmic optimizations to minimize computational overhead and communication costs.
