Abstract: Location brokering technique embodiments are presented that employ sensor data captured by a user's mobile device to determine the device's location, encrypt the location data and store it in a database. The location data is encrypted in such a way that it is possible to determine when a user's mobile device is currently in the same vicinity as another user's mobile device who is a member of the same group as the first user. However, the actual location and relative mobility or immobility of the users cannot be ascertained except by the users themselves via a decryption procedure or by trusted components. Services are provided can read the stored encrypted location data, processes it to determine if group members are in the same vicinity, and either respond to user queries about the location of other members of a group the user belongs to, or push this information to appropriate users.

Abstract: Online advertisements are delivered to one or more users. An authorization to access one or more data streams for a given user is received. The authorization is explicitly granted by the user. The data streams are stored within a user data repository. Upon the user conducting an online action that initiates a dynamic advertisement (DA) request, the authorized data streams for the user are used to generate a customized DA that is optimally relevant to the user. The customized DA is then delivered to the user. The customized DA is also monetized.
