Abstract: In some embodiments, a method inputs a frame sample of a video into a prediction network of a discriminator. The frame sample is analyzed to determine whether the frame sample includes burned-in caption text. When the frame sample is determined to include burned-in caption text, the method sends the frame to a recognition engine to perform a recognition process on the frame sample, performs the recognition process on the frame sample to recognize text in the frame sample, and outputs the text for a service to be performed for the video. When the frame sample is determined to not include burned-in caption text, the method bypasses the recognition engine and does not perform the recognition process on the frame sample.

Abstract: An apparatus is configured to protect the privacy of shared objects by loading shared object into a user memory of a rich execution environment. The shared object has an encrypted segment and metadata. A request for decryption is sent to a trusted execution environment and the encrypted segment is decrypted based on the metadata and a predetermined platform key to produce a decrypted segment. The decrypted segment is written into the shared object. A request to lock the shared object is sent and a memory occupied by the shared object is locked or set to execute only. The lock of the memory region occupied by the decrypted shared object maps the memory region to be non-readable and non-writable to applications executing at a first privilege level and to the operating system kernel executing at a second privilege level.
