A method includes retrieving content playing or to be played by a full-app and/or a micro-app. Additional context information is determined for the content. The content is augmented with the additional context information. The augmented context information is sent to a first micro-app for use in retrieving additional content to play or display along with the content.

Middle partners

In a first embodiment of the present invention, a method is provided for enhancing full-app content playing on a first device, the method comprising: receiving a first selection of a first item from a first micro-app; receiving a second selection of a second item from a second micro-app, wherein the second micro-app is different than the first micro-app and the second selection is in a different format than the first selection; retrieving item context information regarding the first item; retrieving item context information regarding the second item; issuing a query to a micro-app partner based upon both the item context information regarding the first item and the item context information regarding the second item; receiving results from the micro-app partner; and causing at least a portion of the results to be displayed or played.

Multi-user discovery

Systems and techniques are described for blind evaluation of nearest neighbor queries. Locations of multiple users in an original space are received. The locations in the original space are encoded into encoded locations in a transformed space. A relative proximity of the encoded locations in the transformed space is maintained after the encoding. Multiple keys corresponding to the multiple users are generated. Each key enables a reverse transformation of an encoded user location in the transformed space to an original user location in the original space. The multiple keys are provided to the corresponding multiple users, and the encoded locations in the transformed space are provided to a device. An order of computations required to reverse transform the encoded locations in the transformed space to the locations in the original space in the absence of a key is greater than a computational threshold.

Blind evaluation of nearest neighbor queries wherein locations of users are transformed into a transformed space using a plurality of keys

Disclosed are apparatus and methods for providing information that is related to user on-line behavior, which was also used at least partly to generate user scores by one or more behavior targeting processes. A query client may select to receive information from a plurality of different data feeds that are retained within a plurality of different databases by a plurality of different behavior targeting processes. The selectable data feeds generally correspond to different types or aggregations of user on-line behavior. In certain embodiments, information from the selected data feeds for a particular user is compiled and presented in a single, interactive user interface that allows the client to easily view various aspects of such information.
