Abstract: A request, from a requester, is received to view user information on a user's personal site associated with a user. A relationship is determined between the requester and the user. User information is provided to the requester based on the requester's relationship to the user.

Abstract: The present invention discloses an apparatus, a system and a method for short-range sound wave communication. The system realizes non-contact secure transmission by using the sound wave as the data transmission medium, and also can realize a reliable and secure data link directly through an audio connection. The invention systematically constructs multiple end-to-end transmission verification mechanisms for the process of data transmission: transmission data integrity verification, valid time verification, password verification, service data verification and data encryption; and according to the security level of the data, the sending end specifies the requirements for encryption and data verification in the transmission data so as to notify the reception end which verifications should be performed to the data packets, how to perform the verifications, etc. By using the same verification processing manner, operations can be performed to the data (e.g. the payment and settlement function of an account).

Abstract: The disclosed subject matter pertains to systems and/or methods that facilitate associating user activity, such as offline user activity, with an online advertisement. An ad link component can receive information associated with online activity and offline activity of a user, online advertisements, and other information, and can analyze such information. The online activity can include viewing, clicking on, pledging interest in, or obtaining a token related to, an online advertisement. The ad link component can employ ad link criteria to determine whether offline user activity, such as a purchase or other desired activity, can be associated with the online advertisement. If the ad link component determines the offline user activity is associated with the online advertisement, an incentive, which can be based on incentive criteria, can be awarded to the user. A distribution component can distribute the incentive to the account of the user.

Abstract: The present invention facilitates determining a shared context between users of a computer system and dynamically generating a display of the shared context of one user from the perspective of the other user. The data from which a shared context between users may be determined includes data indicating that the users have something in common. Among other data, data indicating that the users have something in common may include data indicating a relationship, past or present, or direct or indirect, between the users. Alternatively, or in addition, data indicating that the users have something in common may include associations with the same individuals, communities, activities, or other special interests, whether those associations are past or present, and explicit or implicit.
