The application is directed to techniques, devices, and systems for updating files. For example, a remote system may store first data representing a first version of a file and second data representing a second version of the file. The remote system may then determine that a first portion of the first data corresponds to a first portion of the second data. Based at least in part on the determination, the remote system may identify a second portion of the first data using the first portion of the first data and identify a second portion of the second data using the first portion of the second data. The remote system may then generate third data representing a difference between the second portion of the second data and the second portion of the first data. Additionally, the remote system may store the third data in association with the file.

Techniques for updating files

Described herein are, among other things, techniques, devices, and systems for generating one or more trained machine-learning models. Also described herein are techniques, devices, and systems for applying a consumption history of a particular user to the trained model(s) to generate score data indicating a correlation between each content-item title and the consumption history. The techniques then determine a ranked list of content items having a highest correlation to the consumption history, which may be used to retrieve videos associated with the most-correlated content items for generating a compilation video composed of these retrieved videos.

Embodiments are directed towards protecting against polymorphic cheat codes in a video game environment. A detour analyzer analyzes game code in client memory for possible hooks to parasite code. For each detected hook to parasite code, hook and/or parasite information is determined to generate a hook/parasite signatures, which are sent to a remote network device. Based on the hook/parasite signatures a weighted combination of scores are generated that is useable to determine a probability value that the parasite code is cheat code. If the determined probability value indicates cheat code, the user of the client device may be banned from future game play. Additionally, the hook/parasite signature information may be used to update the data store to detect polymorphic changes in the cheat code.

Protecting against polymorphic cheat codes in a video game

Embodiments are directed towards providing an interactive game experience whereby a game player may combine game play with a user interface overlaid onto the game that is useable to interact and communicate with other players inside and/or outside of the current game. Through the use of the user interface, a player may select different game sets to play, and rapidly switch between games with different players, while maintaining a real-time interactive chat session, or similar communication session, including, without limit, voice communication sessions. A game client component may launch a game, and then hooks into the game to intercept various input and video functions.

Embodiments are directed towards employing hidden secrets on a client device to detect and deter piracy of a computer application. The computer application is partitioned into components, where a subset of the components is initially provided to the client device. In one embodiment, the computer application is unable to execute properly within the removed or other set of components. The removed components not provided to the client device may then be modified based on hidden secrets information and a verification component and provided over a network to the client device. If the verification component is unable to locate an armed secret, or detects that an armed secret is modified, the computer application may be inhibited from installation and/or execution. In one embodiment, a secret might be unarmed, such that its presence, absence, and/or modification might be ignored.
