1. A media asset capture and processing method, implemented by an electronic device, the method comprising:
capturing a media asset in an electronic device;
storing frame buffer objects of the captured media asset in a Trusted Execution Environment (TEE) of the electronic device;
subsequent to storing the frame buffer objects, processing the media asset in a Rich Execution Environment (REE) of the electronic device in a first state with read-only (RO) access to the stored frame buffer objects and a second state with read-write (RW) access to the stored frame buffer objects;
controlling, in the TEE, the RO and RW access by the REE to the stored frame buffer objects during processing of the media asset; and
subsequent to processing the media asset, authenticating the processed media asset in the TEE.
