Systems and methods for providing capture functionality according to a security policy are provided. A request to capture content is received from a requesting application at a capture controller. The request is evaluated based on the security policy of the capture controller. Based on the evaluation, a determination is made as to whether the request is to be granted completely, denied, or granted subject to a constraint. Capture of the requested content is initiated via capture hardware or software if the request is granted completely or granted subject to the constraint.

Systems and method for streaming video content include downscaling video content using a downscaling model to generate downscaled video content and downloading the downscaled video content as a video stream and corresponding upscaling model to a client device. The system converts received video frames to a video memory format comprising channels having the same memory allocation size, each subsequent channel arranged in an adjacent memory location, for input to the downscaling model. The client device upscales the video stream using the received upscaling model for display by the client device in real-time. A training system trains the downscaling model to generate the downscaled video content, based on associated metadata identifying a type of video content. The downscaled video content and associated upscaling models are stored for access by an edge server, which downloads upscaling models to a client device to select an upscaling model.

Systems and methods for securing audio content in an audio system include a first operating environment executing an audio application and facilitate communications with a server, and a trusted audio processing environment having audio input/output circuitry, a digital signal processor, a tamperproof memory storing a root key serving as a hardware root-of-trust, a key derivation component configured to derive an encryption key or decryption key from the root key and seeding information associated with a server and/or the audio application, an encryption component configured to encrypt the processed audio signal producing an encrypted audio output signal which is accessible to the first operating environment which may transmit the encrypted audio output signal to the server for further processing. A decryption component is configured to decrypt protected audio content received from the server.

Systems, methods, and other embodiments associated with rotating keys for a memory are described. According to one embodiment, a memory system comprises a memory controller configured to control access to a memory and to process memory access requests. Rrekeying logic is configured to rotate a first key that was used to scramble data in the memory and re-scramble the data with a second key by: determining when the memory controller is in an idle cycle and performing a rekeying operation on a portion of the memory during the idle cycle, and pausing the rekeying operation when the memory controller is not in an idle cycle to allow memory access requests to be performed and resuming the rekeying operation during a next idle cycle.
