Redirection of physical media interaction is disclosed. For instance, a read action can be redirected from an optical disc to a secure virtualization module that virtualizes optical discs. The module can take digital packages in one format and present them to optical disc drivers configured to read the content of such packages in a different format. Thus, the module allows for online media content to remain in its native format while being accessible to existing native gaming console resources configured to read content in a different format. In other aspects, the module can perform various security checks on the packages, including hashing the fragments of packages, where such fragments can contain licensing provisions that can be examined by the module. The module itself can be downloaded and installed onto a gaming system or it can be pre-installed.

Read redirection of physical media

Systems, methods, and computer readable media are disclosed for aggregating event records obtained from a plurality of videogame consoles, and generating event objects for each event record of the plurality. Additionally, the event objects can be stored in a database that is exposed to a third party via a connection to a network such as the Internet. In addition to the foregoing, other aspects are described in the claims, drawings, and text forming a part of the present disclosure.

Logging of rich entertainment platform service history for use as a community building tool

A condition on a client that is communicating with a server is determined by issuing a challenge to the client, causing the client to produce a response indicative of the condition. The server compares the response to an expected response to determine if the condition is as expected, and if not, takes appropriate action, such as terminating the connection with the client. The challenge preferably includes parameters and a code segment that causes the client to produce the response by executing the code segment. The code segment could perform a one-way hashing algorithm of a portion of memory indicated in the parameters. The server can thus determine if the client is using a modified basic input output system, modified software, pirated software, or whether other conditions exist on the client. The challenge can be changed to prevent the client from returning a false, predetermined response to the challenge.

Handling failed client responses to server-side challenges

Multiple versions of a runtime system, such as a software emulation application that emulates a legacy hardware architecture, are allowed to co-exist in the memory of a new hardware architecture. The operating system software of the new hardware architecture reads configuration data from a database or table to decide which version of the runtime system is desirable for an application program or game that is being loaded or is currently running, and, if a match is found, only that runtime system is invoked. To reduce storage footprint, the different versions of the runtime system may be stored using 'differential patching' techniques. In this configuration, the operating system will always launch the same basic runtime system binary, but it will select a different differential patch to apply at run-time based on the title as determined during the database lookup. In this fashion, future changes to the runtime system to correct software bugs, incompatibility issues, and the like only need to be tested for the relevant target application programs or games.

Systems and methods for supporting multiple gaming console emulation environments

An exemplary implementation of a security gateway for online console-based gaming operates as a gateway between a public network (e.g., the Internet), and a private network (e.g., an internal data center network). The security gateway allows secure communication channels to be established with game consoles via the public network, and allows secure communication between game consoles on the public network and service devices on the private network.

Security gateway for online console-based gaming

Official results for an online game session are determined by an arbitration server based upon reports received from each game console participating in the game session. The reports provide results for all of the players participating in the games session. Before starting the game session, each game console registers the players using it with the gaming service, so that a player who disconnects mid-game can be identified. If the results reported differ, predefined arbitration rules are applied to determine the official results. If a game console cannot report because it is being packet bombed, a different protocol is used to transmit a data packet to the arbitration service indicating that the gaming console is being packet bombed. While not required, the arbitration server can use historical data recorded for each player to apply the predefined arbitration rules in determining the official results.

Arbitration of online game results using an arbitration server and method

A trust rating factor (TRF) based upon data collected for players participating in previous online games sessions is used in determining official results for an online game session when different results are reported by the participants. Counters corresponding to each of a plurality of parameters related to conditions that arise during or at the end of a game session are employed in determining the TRF for each player. For example, if one of the players may have experienced a packet bombing that interrupted normal data communication, a counter related to that condition will be incremented for all players in the game session. If all of the players report results that are consistent at the end of the game session, the TRF of each player is improved. A separate TRF is determined for each game title in which a player participates.

Challenge and response interaction between client and server computing devices

A web server arrangement is provided having a kernel-mode listener service capable of receiving web requests and providing the web requests to at least one user mode web application. The listener service and the web application are operatively configured by a user-mode administrative process. The administrative process is configured to determine when a web application needs to be recycled and to selectively recycle web applications.

Ensuring the health and availability of web applications

A way of reducing the impact of denial of service attacks is presented. For each connection request received by a server, the server attempts to establish a connection to accommodate the corresponding request. For each connection request that the server cannot currently handle, the connection request is placed in a backlog queue for future handling. If one or more of the backlog queues have entries, connection sockets that have connections but no received request data are identified and disconnected. Such connection sockets would be highly suspect of being generated as a result of denial of service attacks. Upon disconnection, resources are freed for legitimate requests thereby improving server performance even during denial of service attacks.
