Systems, methods, devices, and computer program products are described for using context-aware recommendation techniques to facilitate content discovery on a mobile device platform. In particular, the context-aware recommendation techniques evaluate both a current device context and a social context to generate application relevance scores for each of a number of applications downloaded to a mobile device. Application representations on a graphical user interface (GUI) of the mobile device are rearranged, resized, and/or otherwise affected according to their respective application relevance scores. In certain configurations, one or more applications are pinned, thereby altering (e.g., reducing or eliminating) how changes in their respective application relevance scores affect display of their respective application representations on the GUI of the mobile device.

Application relevance determination based on social context

Methods and systems for receiving targeted content messages on a wireless access terminal (W-AT) are disclosed. For example, a particular method may include selecting at least one reception time based on a user profile and a targeted content message delivery schedule, and receiving a targeted content message at the selected reception time.

Methods and systems for providing user information from a wireless access terminal (W-AT) to a remote apparatus without revealing a primary identity of the user of the W-AT include generating an alternate user identifier for the W-AT, and providing the alternate user identifier and first information related to targeted-content-message information and/or user profile information to the remote apparatus.

Methods and systems for providing targeted information using identity masking in a wireless communications device

A targeted-content-message-related profile for use with wireless access terminals (W-ATs) may be generated by one or more usage-related rules on the W-AT itself. The usage generate rules may be used by the W-AT to generate a user profile, with the usage-related rule providing a dynamic property to the user profile. All or part of the user profile may then be used as a targeted-content-message-related profile for targeting content messages.

The method also includes determining popularity metrics for one or more content data records from the plurality of content data records based on the data included in each of the at least some of the plurality of messages representative of the number of times the respective at least one content data record was used on the respective sending device.

Content management in peer-to-peer systems

Systems and methodologies are described that facilitate digital rights management in a wireless communication environment. Generally, content (e.g., data files, video images, etc.) can be downloaded and maintained in its encrypted state to ensure protection of digital rights. Consequently, programming applications that utilize such content decrypt the content at the time of use (e.g., playback or access). A file interface can be provided that allows applications to access encrypted content utilizing a standardized file I/O interface. Decryption of content can be transparent to individual applications utilizing encrypted content. Therefore, modifications cryptographic algorithms or procedures and changes in key sizes need not affect the programming applications.
