Techniques for enhancing security for thin client devices in hybrid edge cloud systems are described. In accordance with various embodiments, the hybrid system includes a cloud computing platform (e.g., the cloud) and an edge device (e.g., the edge). The cloud extracts key(s) for authentication and session establishment. The cloud also utilizes the key(s) to establish a session between the edge and a client device. The cloud additionally authorizes a content request from the client device for a media content item over the session and extracts a content key upon successful authorization. The edge caches the key(s), obtains the content key at the time of receiving the content request from the client device and transmits the content key and the key(s) with the media content item to the client device.

Techniques for countering cheats in a multi-player gaming environment are described herein. In accordance with various embodiments, a server includes a cheating analyzer running on processor(s) and a non-transitory memory for storing cheat data and counter cheat data. The server identifies suspected cheating in a game and determines a probability of the suspected cheating based on the cheat data. The server also selects a counter cheat of the suspected cheating corresponding to the probability value based on the cheat data and the counter cheat data. The server then applies the counter cheat approximate the probability value in the game. In some embodiments, the server deploys local copies of the cheating analyzer to client devices, including sending at least a portion of the cheat data and/or counter cheat data. The local copies facilitate the cheat identification, the probability determination, the counter cheat selection, and/or the application of the counter cheat.

Techniques for media content tamper protection and detection are described. In some embodiments, the protection method is performed at an encoder. The encoder obtains a first sequence of signatures within a group of pictures and a second sequence of signatures for audio frames corresponding to the group of pictures. The encoder then combines the first sequence of signatures and the second sequence of signatures to generate a combined signature, and the combined signature is then embedded in a transport stream for transmission to a client device. In some embodiments, the detection method is performed at a client device, where the client device, in response to detecting a first message in the transport stream, starts calculation of signatures for a group of pictures and corresponding audio frames. The client device then uses the calculated signatures to validate an expected signature for the group of pictures and the corresponding audio frames.
