There is provided a method and a system for preventing wall-hacking by using server side ray tracing to filter data packets to be provided to user devices during a multiplayer video gaming session. Map information and player updates indicative of player actions are received, and an acceleration structure is generated. Primary rays from the virtual frustum associated with players are generated and intersections between rays and players geometries on the map are determined based on the acceleration structure. The visibility matrix is generated based on the determined intersections. The visibility matrix includes pair wise visibility information between each player. Data packets provided to each user device are then filtered based on the visibility matrix.

Embodiments of the present disclosure provide systems, methods, and computer storage media directed to anti-cheat detection in online multiplayer video games. An anti-cheat kernel driver adapted to validate and secure a system state of a gaming device is loaded during a booting process of the gaming device. The loaded anti-cheat kernel driver ensures that the system state cannot be tampered with from the time of boot through the duration of gameplay. The loaded anti-cheat kernel driver can also receive anti-cheat modules communicated to the gaming device from an anti-cheat server, so that anti-cheat modules are received and executed on an ad hoc basis dictated by the anti-cheat server. The anti-cheat server can autonomously manage the anti-cheat operations performed on a kernel layer or application layer of the gaming device, and conduct anti-cheat mitigation operations if necessary.

A cheating enforcement system and method determines if a player profile that is to play an online game is linked to another player profile that had been identified as cheating. If such a link is found, then one or more penalties may be imposed on the player profile, so that penalties for cheating cannot be averted by a player by opening a new player profile to play the online game. If a certain period of time has transpired since cheating was detected for the other player profile, then the one or more penalties may be removed from the player profile. The penalties imposed on the player profile may include server-side hit detection, latency penalty, damage scaling, and/or dropped moves. In the case of a chain of linked player profiles, severity of penalties may increase based on the number of linked accounts where cheating use was detected.

A method and apparatus to objectively identify and classify cheating behaviors in players of virtual games, namely identity fraud or any type of software-based fraud or other unsportsmanlike or unethical behaviors. A method to use that information to inform the players, the game, the game servers, or any other external entity of the cheating behaviors found, allowing these entities to trigger disciplinary or punitive actions as per the regulations of the game or competition.

This method for reading a video stream comprises a step of comparing a datum characteristic of a behavior of a user with a set of predetermined thresholds, each of which, when it is crossed, characterizes an abnormal behavior of the user, a step of signaling an abnormal behavior if at least one predetermined part of these thresholds is crossed, and, otherwise, the absence of this signaling of an abnormal behavior, and a step of executing a counter-measure which makes it more difficult or impossible to access the set of information items contained in a first baseband video stream on the basis of various proofs of a second baseband video stream composed by a first terminal, this execution step being triggered automatically in response to the signaling of an abnormal behavior and not being triggered in the absence of this signaling of an abnormal behavior.

An exemplary information processing system is configured to create a route formed by arranging, in a virtual space, a plurality of route parts each associated with a design; determine whether the route created by the user contains a forbidden symbol or a forbidden word. When the route created by the user contains a forbidden symbol or a forbidden word, uploading of the route created by the user to the server is prohibited.

A guest management method and system for an online multi-player virtual reality environment or social networking site. A network interface receives guest access requests from guest clients and input data from a plurality of remotely-located clients. The input data is operative to control avatars associated with the clients in a modeled virtual reality environment. A memory holds program instructions for determining whether the guest access is associated with a member client. If the guest access request is associated with the member client, then the guest client is allowed to access the virtual reality environment via a guest avatar. The guest avatar's movements in the virtual reality environment are restricted based on a location of a member avatar controlled by the associated member client. For example, the guest avatar may only be permitted to move within an area that is bounded by a perimeter about the member avatar.

A server computer is connected to a plurality of client computers through a network, and controls objects in a Metaverse accessed by the client computers. The server computer includes a storage unit for storing an object ID specifying an object accessible in the Metaverse by the plurality of client computers and authenticity information associated with the object ID. The authenticity information indicates that the object is genuine. The server computer also includes a communication unit for communicating with each of the client computers. The server computer also includes an enquiry unit for causing the communication unit to transmit the authenticity information corresponding to the object ID to at least one of the plurality of client computers upon receipt of an enquiry request to enquire about the object ID of the object from one of the plurality of client computers.

Examples herein include systems for detecting cheating and changes in mental performance in card games, including bridge. The system can acquire board data for multiple events, the events including bridge games. For each event, determining performance values for a player based on the board and play data, wherein the performance values may additionally be based in part on timing data. The system can detect a deviation of by comparing the performance values against a threshold, wherein the threshold is based on past performance of known cheating players or the individual player. Then the system can alert a user when the likelihood of cheating or other changes exceeds a threshold.
