Abstract: A system and method are described below for encoding interactive low-latency video using interframe coding. For example, one embodiment of a computer-implemented method for performing video compression comprises: logically subdividing each of a sequence of images into a plurality of tiles, each of the tiles having a defined position within each of the sequence of images, the defined position remaining the same between successive images; detecting motion within the sequence of images occurring at each of the positions of each of the tiles; and encoding each tile within each image of the sequence of images using a first compression format or a second compression format, wherein the frequency at which a particular tile is encoded according to the first compression format across the sequence of images is based on the detected amount of motion at the position of that tile across the sequence of images.

Abstract: Methods, systems, and computer programs are presented for automated detection and mitigation of Denial of Service (DoS) attacks. One method includes an operation for collecting traffic data from service network routers that provide users access to a service. The traffic data is applied to security rules to identify a blacklist of illegitimate users to be blocked. Further, the method receives from the one or more servers a whitelist with information regarding legitimate users and their geographical location. A safe blacklist is determined for each router based on the blacklist and the whitelist, and the respective safe blacklist is sent to each router. Legitimate users are not blocked from accessing the service, but an illegitimate user spoofing a legitimate user is blocked by the routers when trying to access the service from a geographic location that is not the geographic location of the legitimate user.

Abstract: An enterprise computer network is monitored to detect and neutralize security breaches. In a first case failed login attempts to multiple target machines are noted and if they come from one machine or a small number of originating machines, a password spraying attack from the originating machines is indicated, resulting in the originating machines being segregated from the system. In another case, multiple indicators of compromise are used to determine whether an enterprise machine is infected with malware and only if multiple indicators are present is the machine segregated from the system.

Abstract: A video server is configured to provide streaming video to players of computer games over a computing network. The video server can provided video of different games to different players simultaneously. This is accomplished by rendering several video streams in parallel using a single GPU (Graphics Processing Unit). The output of the GPU is provided to graphics processing pipelines that are each associated with a specific client/player and are dynamically allocated as needed. A client qualifier may be used to assure that only clients capable of presenting the streaming video to a player at a minimum level of quality receive the video stream. Video frames provided by the video server optionally include overlays added to the output of the GPU. These overlays can include voice data received from another game player.

Abstract: To prevent legitimate message recipients from forging new messages and to encrypt messages for a specific set of recipients (channel), a root key is encrypted and combined with a base session management key to render a combined root key, which in turn is encrypted with a public key of at least one recipient device to render a session management key. The public key of each of “N” intended recipient device encrypts the combined root key to render “N” session management keys. The session management keys are then combined with the combined root key to render a multicast root key, which is signed with a private key of a sending device. The signed multicast root key is combined with the session management keys to render an encrypted, signed multicast root key that is used to encrypt digital information prior to transmitting the digital information.

Abstract: Methods and systems that enhance motion capture capabilities. In one such method, the motion capture system enables a user to set parameters, based on hue, lightness, and saturation, for example, to assist in identifying and searching for motion capture markers that are applied to real-life subjects. In another implementation, the motion capture system enables a user to determine a distance between a master marker and a slave marker, and to use that distance to establish bounding boxes for searching for the slave marker in subsequent frames. Further, in some implementations, the motion capture system further uses the distance when rendering an animated scene based on the motion capture session to estimate the position of the slave marker when the slave marker is not visible in a captured frame.
