Described are various mechanisms and techniques for influencing or controlling a content update schedule for a content-based software application on a mobile device. A content server issues one or more commands to the mobile device that establish a content update schedule for the mobile device. The mobile device then performs content update sessions with the content server based on that schedule. During any one or more refresh sessions, the content server delivers another command to establish a new content update schedule. This system provides the advantage of allowing the content server to regulate how frequently the mobile device retrieves new content.

Methods and devices provide for creating, managing, modifying, and/or enforcing flexible digital rights management license policies for protecting games, media, data, or other software with a time-based license. Embodiments are especially directed toward situations in which a source of time is unavailable, untrustworthy, or unreliable. Licenses are defined by a small number of parameters. Parameter values may be defined by and included with protected content or applications. The parameter values may be chosen to define and enforce a desired level of compromise between usability and security characteristics.

Methods and apparatus for providing an application credential for an application running on a device. In one embodiment, a method provides an application credential to an application running on a device, wherein the application credential is used by the application to authenticate to a data server. The method comprises receiving a request to generate the application credential, wherein the request includes an application identifier. The method also comprises generating the application credential using the application identifier and a master credential associated with the device.

An application's access to storage is limited on a per application basis. The application is granted access to a portion of the storage. The application may manipulate that portion of the storage by creating distinct file structures within that portion, modifying, reading and writing files contained therein. The application is denied access to the storage area outside the granted portion. Similarly, other applications stored in the storage area follow a similar paradigm. In one embodiment, the storage area is a hierarchical file structure and applications are stored as children in the file structure. The applications, however, are mapped to indicate each are stored at the root of the file structure to prevent access to other areas of the file structure. In another embodiment, the file structure supports a shared directory that multiple applications are mapped to, also as a root directory but to another drive.

The present invention provides safe and secure application distribution and execution by providing systems and methods that test an application to ensure that it satisfies predetermined criteria associated with the environment in which it will execute. Furthermore, by using rules and permission lists, application removal, and a modification detection technique, such as digital signatures, the present invention provides mechanisms to safely distribute and execute tested, or untested, applications by determining whether the application has been modified, determining if it has permission to execute in a given wireless device environment, and removing the application should it be desirable to do so.
摘要:
Systems and methods consistent with the present invention provides safe and secure application distribution and execution and controls the risk of providing a test environment associated with the testing of applications. Test enabled permissions are created and distributed to selected application test entities. A management function is used to aid in distributing the test-enabled permissions. The risk is controlled by providing closer scrutiny of the identity of the test entity prior to distributing a test enabled permission to the test entity, providing expiration times associated with the test enabled permissions, and limiting the number of test enabled permissions distributed. The management function tracks the distribution of the test-enabled permissions.
