Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G  H

Claim 0:
1. A method of operating an electronic device including a neural network model, the method comprising:
receiving, during a non-secure mode of the electronic device, neural network model data and raw data, the neural network model data encrypted by digital rights management (DRM) and the raw data includes a plurality of frame data corresponding to a plurality of frame images;
changing, based on the receiving the neural network model data and the raw data, an operation mode of the electronic device from the non-secure mode to a secure mode;
decrypting, during the secure mode, the neural network model data encrypted by the DRM based on an authentication or verification of a license obtained by the electronic device;
executing, during the secure mode, the neural network model based on decrypted neural network model data; and
performing, during the secure mode, an inference operation on the raw data using the executed neural network model,
wherein the neural network model data encrypted by the DRM is received as a first DRM package,
the decrypting the neural network model data includes decrypting the neural network model data included in the first DRM package, and
the inference operation is performed on the plurality of frame data using the decrypted neural network model data.
