Method, apparatus, computer program product and computer readable medium are disclosed for privacy protection. A method may comprise: receiving encrypted data from a top participating node of a participant chain, which comprises a plurality of participating nodes; and decrypting the encrypted data, wherein the encrypted data comprise a plurality of encrypted sensory data obtained respectively by said plurality of participating nodes.

Apparatus, method and computer program product for privacy protection

An approach is provided for discovering social ties among users based on cloaked trajectories. In a method, cloaked regions of a first trajectory of a first user and cloaked regions of a second trajectory of a second user are transformed to corresponding semantic regions, respectively, wherein a semantic region is expressed with a semantic meaning of a corresponding cloaked region. The transformed semantic regions are mapped into nodes of a hierarchical semantic tree, wherein each node of the hierarchical semantic tree corresponds to a semantic region. According to relationships between nodes mapped to semantic regions of the first trajectory and node mapped to the semantic regions of the second trajectory, social ties among the first user and the second user can be inferred.

A method, apparatus, system for image processing is provided that creates an object note for a picture. The method, apparatus or system includes: automatically obtaining picture description information from a picture source, wherein the picture description information at least partly have been formed automatically; obtaining annotation information from at least two object sources, wherein the two object sources are different from the picture sources, automatically fusing the said annotation information from the two object sources to form fused annotation information, and attaching said fused annotation information to the picture to create the object note for the picture.

Method, apparatus or system for image processing

Techniques for expanded content tag sharing include determining that a first user is associated with content provided by a different second user. Data is recorded that indicates the first user is authorized to associate a different third user with the content provided by the second user, without further input by the second user. In some embodiments, the data that indicates the content provided by the second user includes data that indicates a plurality of contents. Some techniques include determining a message received from a first user indicates a portion of content associated with the first user, and a second user. The portion of the content is rendered on an apparatus of the second user. The second user is prompted for associating, with the portion of the content, an item identifier, such as text or another user, for the portion of the content.

Method and apparatus for expanded content tag sharing

An approach is provided for determining the intent of a question and determining an appropriate audience to answer the question based on the intent of the question. The approach comprises processing and/or facilitating a processing of a query to cause, at least in part, a determination of one or more topics of the query based, at least in part, on one or more user preferences. The approach also comprises processing and/or facilitating a processing of the query to cause, at least in part, a determination of a classification of the query, The approach further comprises determining an audience comprising one or more candidate audience members for the query based, at least in part, on the classification of the query and the one or more topics of the query.

Method and apparatus for processing a query based on associating intent and audience

An approach is provided for providing a trust level to access a resource. A system receives a request at a device, from a first user, to access a resource associated with a second user. The resource is further associated with a predetermined privacy level. The system calculates a trust level between the first user and the second user based, at least in part, on a trust metric. The system then determines whether the trust level meets the predetermined privacy level and grants an access right to the resource based, at least in part, on the determination.

Method and apparatus for providing a trust level to access a resource

A system and method for sharing user information between online services may determine a degree of relationship between the services to determine how much, and what precision level, of user information should be shared. In one example, the user information may be global positioning system (GPS) location information for the user, and requesting users (or systems) receive different levels of the location information based on their respective relationships to the user and/or the user's online information service. The relationship between services may be user-defined using onscreen graphical tools. The determination may also include determining the levels of activity of users at the services, whereby information regarding less active users is less detailed than information regarding active users.
