Latest Patents

One of her latest patents is titled "Method and system for secure aggregation protocol for protecting privacy of individual data sets." This invention provides a secure aggregation protocol that enables federated learning of machine learning models while safeguarding the privacy of individual data sets associated with participants. The method includes a setup phase that utilizes public key—secret key pairs for verifying signatures and facilitating secure transmissions of encrypted messages containing datasets to be aggregated. Additionally, an aggregation phase employs a random oracle/hash function to facilitate the integration of newly submitted datasets into the preexisting aggregated dataset.

Another notable patent is "Secure aggregation of information using federated learning." This method allows for the learning of a shared machine learning model while preserving the privacy of individual participants. It involves receiving encrypted user inputs from a group of users and, upon reaching a threshold number of inputs, transmitting a list of the group to each user. The process continues with users indicating mutual agreement regarding a shared secret, and once a sufficient number of agreements are received, information about the shared machine learning model is determined by combining the encrypted user inputs.
