Abstract
Described herein is a system and method for utilizing a virtual secure mode instance to protect an artificial intelligence model from unauthorized access (e.g., inspection, copying) during execution of an application utilizing the AI model (e.g., training and/or inference) on a client device. An encrypted artificial intelligence model is received in a virtual secure mode instance of the client device. The encrypted artificial intelligence model is decrypted in the virtual secure mode instance using a decryption secret. The decrypted artificial intelligence model is stored in the virtual secure mode instance. An application that utilizes the decrypted artificial intelligence model is executed (e.g., training and/or inference) in the virtual secure mode instance.
