The network 306 may comprise a wireline network, wireless network (e.g., a cellular network, wireless local area network, wireless wide area network, some combination thereof, or the like), or a combination thereof, and in one embodiment comprises the internet.

In the example system illustrated in FIG. 3, the user terminal 304 may be used by one or more users to play a game or use an application. The user terminal 304 in combination with the verification apparatus 302 may be configured to enforce user privileges related to the game being played on the user terminal 304. In this regard, the user terminal 304 may be configured to capture an image of a user of the user terminal 304 and provide the image to the verification apparatus 302 to enable the verification apparatus 302 to verify the identity of the user of the user terminal 304, such as in accordance with any of the verification methods described further herein below with respect to the verification apparatus 102. The verification apparatus 302 may provide the verification results to the user terminal 304 so that the user terminal 304 may enforce user privileges based on the verification results. Accordingly, in embodiments such as that illustrated in FIG.3, it will be appreciated that at least some aspects of the user interface 116, verification circuitry 120, and/or image capture circuitry 118 may be embodied on the user terminal 304. Therefore, it will be appreciated that where the verification circuitry 120 is described to cause a graphical user interface, prompt, image, game data, and/or the like to be displayed, the image verification circuitry 120 may cause display on a display operably connected to the verification apparatus 102 or may cause display on a display of a remote user terminal to which data is transmitted over a network. Similarly, it will be appreciated that where the verification circuitry 120 is described to be configured to access an image captured of a user of a computing device being used to play a game, the verification circuitry 120 may be configured to access an image captured by image capture circuitry 118 of a user of the verification apparatus 102 or may be configured to access an image captured by a camera of a remote user terminal 304 that is provided to the verification apparatus 302 to facilitate verification of the user. Further, where the verification circuitry 120 is said to be configured to determine a user input and/or to make a determination based on user input, the verification circuitry 120 may be configured to make the determination based on user input to a user interface 116 of the verification apparatus 102 or may be configured to make the determination based on a user input to a remote user terminal, an indication of which is transmitted to the verification apparatus 102 over a network.

In another example embodiment of the system 300, aspects of the verification circuitry 120 may be distributed between the user terminal 304 and verification apparatus 302. In this example embodiment, the verification apparatus 302 may handle certain processing tasks required for user verification, such as implementing a face recognition algorithm for identifying a user, while actual enforcement of access permissions may be handled by the user terminal 304 based on user verification (e.g., face recognition) results determined by the verification apparatus 302 and provided to the user terminal 304.

FIG. 4 illustrates a system 400 for facilitating user verification according to an example embodiment of the invention. The system 400 comprises a verification apparatus 402 and a game server 404 configured to communicate over the network 406. The network 406 may comprise a wireline network, wireless network (e.g., a cellular network, wireless local area network, wireless wide area network, some combination thereof, or the like), or a combination thereof, and in one embodiment comprises the internet. The verification apparatus 402 may, for example, comprise an embodiment of the verification apparatus 102. The verification apparatus 402 may be configured to use game data for a game provided to the verification apparatus 402 by the game server 404 to allow a user(s) of the verification apparatus 102 to play the game on the verification apparatus. Accordingly, it will be appreciated that where a user of a verification apparatus, user terminal, or other computing device is described to be using the computing device to play a game, the game may be executed on the computing device being used to play the game or may be at least partially executed on a network server and accessed remotely by the computing device used to play the game.

Returning now to FIG. 1, some example embodiments will be described with respect to the verification apparatus 102. These example embodiments will be described within the context of multiplayer gaming on a single computing device. However, it will be appreciated that user verification in accordance with the example embodiments is not limited to usage in the context of multiplayer gaming, but can be applied to any application wherein a plurality of users are using the application and certain features or data are privileged to only a subset of the plurality of users.

At the outset of a game, players may register themselves by providing registration information to the verification apparatus 102. In this regard, the verification circuitry 120 may be configured to detect initiation of a multiplayer game and prompt players to register themselves. The verification circuitry 120 may be configured to determine the registration information and register a player based on the registration information. The registration information may comprise a reference image of the player. The reference image may comprise an image of at least a portion of a player' s face and/or some other distinguishing visual feature associated with the player's person that may later be used to verify the player's identity. The registration information for a player may further comprise a name of the player. The name of the player may comprise the player's legal name, a nickname, a user handle, and/or the like and may, for example, be entered by the player via the user interface 116.

When registering a player, the verification circuitry 120 may be configured to obtain a reference image captured subsequent to initiation of the game. In one example embodiment, the verification circuitry 120 is configured to direct the image capture circuitry 120 to capture a reference image of a player. As another example, a player may trigger capture of a reference image, such as through an input to the user interface 116. The player may then select the captured image as a reference image for use in verifying the player's identity during game play.

Alternatively, a player may have preregistered for a game prior to initiation of the game, such as during a previous gaming session. In this regard, a registration profile comprising a reference image for a player may be stored in the memory 112. When registering himself for a current gaming session, a player may select his stored registration profile for use in the current gaming session. The verification circuitry 120 may accordingly be configured to access a stored registration profile and extract the player' s reference image, other registration data, profile data, and/or the like to enable registration of the player for a current gaming session.

During play of the multiplayer game, a subset of the players may be authorized at any given time to perform an action in the game. The player(s) that comprise the subset of players authorized to perform an action in the game at any given time may be determined based on the rules of the game being played. For example, in a turn-based game, the player authorized to perform an action may rotate in turns among the players playing the game.

The verification circuitry 120 may accordingly be configured to verify that a current user of a computing device being used to play the multiplayer game is a player presently authorized to perform an action in the game prior to granting game play privileges to the user. In an example embodiment, the image capture circuitry 118 is configured to capture an image of a current user. The image capture circuitry 118 may capture the image in response to instruction from the verification circuitry 120. For example, the verification circuitry 120 may instruct the image capture circuitry 118 to capture an image of the user in response to a game play event (e.g., a rotation in turn). As another example, the verification circuitry 120 may instruct the image capture circuitry 118 to capture an image of the user in response to an assertion by the user entered via the user interface 116 that the user is a player presently authorized to perform an action in the game.

In an example embodiment, the verification circuitry 120 is configured to cause display of an indication of a player that is presently authorized to perform an action in the game, such as in response to a game play event bringing about a change in the player presently authorized to perform an action in the game (e.g., a rotation in turn). The indication may comprise the reference image of the player, the name of the player, or other indication of the player, such as may have been provided as registration information when the player was registered. The image capture circuitry 118 and/or verification circuitry 120 may be configured to cause capture of an image of a current user in response to determining an assertion that the user is the indicated player. This assertion may comprise an active assertion by the user. For example, the user may enter or select a "player ready" indication or the like via the user interface 116. Alternatively the assertion may comprise a passive assertion by the user. For example, the verification circuitry 120 may detect a change of user within the field of view of the image capture circuitry 118, such as may occur when a computing device being used to play the game is passed from one player to another. The verification circuitry 120 may be configured to cause capture of an image of the current user by the image capture circuitry 118 in response to determining the assertion.

The image captured of the current user may comprise an image of at least a portion of the user's face and/or some other distinguishing visual feature associated with the user's person that may be used for verification of the user's identity. In some embodiments, the image captured of the current user may comprise a video stream or video capture of the user. The verification circuitry 120 may accordingly be configured to extract a frame from the video and/or to use a segment of the video to facilitate verification of the identity of the user.

The verification circuitry 120 may be configured to access the image captured of the current user and determine whether the user is a player that is presently authorized to perform an action in the game by comparing the image of the user to the reference image(s) for the player(s) presently authorized to perform an action in the game. In this regard, the verification circuitry 120 may be configured to compare a distinguishing visual feature of the player in a reference image to a distinguishing visual feature of the current user in the image of the user to determine if the user matches the player presently authorized to perform an action in the game. For example, the verification circuitry 120 may be configured to use a face recognition algorithm to determine whether one or more facial features of the current user match one or more facial features of a player presently authorized to perform an action in the game. It will be appreciated that the verification circuitry 120 may be configured to use any face recognition algorithm or any combination of face recognition algorithms in performing user verification. Example face recognition algorithms that the verification circuitry 120 may use when comparing an image of a current user to a reference image of a player presently authorized to perform an action in a game include Principal Component Analysis (PCA), Independent Component Analysis (ICA), Linear Discriminant Analysis (LDA), Evolutionary Pursuit (EP), Elastic Bunch Graph Matching

(EBGM), a kernel method, trace transform, Active Appearance Model (AAM), a 3-D morphable face model, a 3-D face recognition algorithm, a Bayesian framework, a Support Vector Machine (SVM), a Hidden Markov Model (HMM), and/or the like.

If the verification circuitry 120 determines that the current user is a player presently authorized to perform an action in the game, the verification circuitry 120 may be configured to grant game play privileges to the user. In this regard, the verification circuitry 120 may be configured to grant the user the privilege to manipulate game action (e.g., to move a game piece, manipulate a character in the game, engage in a play, and/or the like). As another example, the verification circuitry 120 may be configured to cause or otherwise allow display of personal game data that is privileged to the player presently authorized to perform an action in the game that had been hidden from the user prior to verification of the user's identity. This personal game data may comprise any game data that is to be maintained in secrecy from other players. For example, the personal game data may comprise the cards in the player's hand in a card game.

If, on the other hand, the verification circuitry 120 determines that the current user is not a player presently authorized to perform an action in the game, the verification circuitry 120 may be configured to deny the user game play privileges. In this regard, the verification circuitry 120 may, for example, be configured to prevent the user from manipulating game action. As another example, the verification circuitry 120 may be configured to not allow display of personal game data privileged to the player presently authorized to perform an action in the game.

Operation 510 may comprise accessing an image of a user of a computing device being used by the players to play the multiplayer game. Operation 520 may comprise determining based on the image accessed in Operation 510 whether the user is a player that is presently authorized to perform an action in the game. In this regard, Operation 520 may comprise comparing the image of the user to a reference image(s) for the player(s) presently authorized to perform an action in the game, such as by using a face recognition algorithm. Operation 530 may comprise granting game play privileges to the user only when the user is determined to be a player presently authorized to perform an action in the game.
