Abstract
Methods, systems, and devices for improving security of media streams are disclosed. The system can receive a decoded media stream from a media decoding pipeline that receives and decodes an encoded media stream. The system can identify, based on the decoded media stream, a set of features to generate, and generate the set of features using the decoded media stream. Such features may include luma histograms, pixel intensity data, motion vectors, edge detection, audio gain, tonal information, pitch information, among other types of features. The system can provide the set of features to a processor executing a machine-learning model, wherein the processor executing the machine-learning model is prevented from accessing the decoded media stream by the device.
