Abstract: A group licensing scheme for validating groups of virtual objects within a distributed virtual world is provided. Each of a number of distributed virtual world servers hosts a cell, or virtual space, of the virtual world. In operation, a first virtual world server categorizes virtual objects into a number of groups. Either before or after creating the groups, the first virtual world server validates each virtual object individually. Once the virtual objects are validated and the groups are formed, the first virtual world server generates a group license for each of the groups. When a group of virtual objects or an avatar associated with one or more groups of virtual objects moves to a virtual space hosted by a second virtual world server, the corresponding group licenses are provided to the second virtual world server, which validates the one or more groups of virtual objects based on the group licenses.

Abstract: Techniques for improving scrolling performance in a web-based data grid. In one set of embodiments, when a user scrolls through a data grid rendered in a viewport of the user's web browser, client-side code executing in the web browser can detect whether a scroll event has occurred that requires a portion of the viewport to be filled/refreshed with data from a server. The client-side code can further determine whether the scroll event is a short scroll or a long scroll, and can send a request to the server that indicates the type of scroll event. If the scroll event is a short scroll, the server can determine a first amount of data to fetch based on one or more first parameters. If the scroll event is a long scroll, the server can determine a second amount of data to fetch based on one or more second parameters.

Abstract: A virtual environment firewall receives a message having a request from a virtual environment entity intended for a virtual environment controller. The virtual environment firewall determines whether the request complies with one or more governance rules of the virtual environment controller. If the request does not comply with the one or more governance rules, the virtual environment firewall processes the message to prevent the request from being processed by the virtual environment controller.

Abstract: A system and method are provided for creating communities based on a semantic understanding of content requested by a number of user devices. More specifically, a mediating server operates to interconnect a number of user devices to destination servers. In operation, the mediating server routes requests from the user devices to the appropriate destination servers. The mediating server examines the responses from the destination servers to gain a semantic understanding of the content requested by the user devices. Thereafter, the mediating server establishes communities for the user devices based on the semantic understanding of the content requested by the user devices. For example, the mediating server may invite users of the user devices that have requested semantically similar content to join a chat session around a common topic.

Abstract: A method of validating an identifier is disclosed. In one embodiment an authenticating party system receives an identifier for validation and determines a first validation code associated with a current value of a counter. The first validation code is compared with the received identifier and, in the event that the identifier does not match the first validation code, the authenticating party system compares the identifier with one or more further validation codes associated with respective other values for the counter, said respective other values comprising N consecutive counter values succeeding the current value of the counter. If the identifier matches one of the further validation codes associated with a respective other value for the counter, the current value of the counter is updated to correspond with the respective other value for the counter associated with the matching further validation code.

Abstract: A system and method for influencing behavior in a virtual environment. A virtual environment identifies a hotspot of activity that is, or may, cause lag in the virtual environment.

Abstract: A method of authenticating a remote service (104) to a user (102) via a communications network (106) is disclosed. The remote service (104) obtains a service authentication code that has been generated, using a code generation algorithm, based on a first secret key. The service authentication code is communicated to the user (102) via the communications network (106) and received, or entered, into an authentication device (106) associated with the user (102). The authentication device (106) then generates, using the same code generation algorithm, an expected code value based on a second secret key and compares the expected code value to the service authentication code. Responsive to the comparison, and in the event that the expected code value correlates with the service authentication code, the authentication device (106) generates a response that indicates to the user (102) the authenticity of the remote service (104).

Abstract: A mediating server operates to interconnect a number of user devices to network servers. In order to receive customized content from the network servers, the user devices provide device profiles to the network servers via the mediating server within or in addition to requests for content. As the device profiles pass through the mediating server, the mediating server obtains the device profiles and stores the device profiles in a device profiles database. The mediating server may then classify the user devices based on the user profiles using a classification algorithm, which may include one or more classification rules for each of a number of classes. Thereafter, the mediating server may provide one or more services based on the device profiles, the classification of the user devices, or a combination thereof.
