A method including: receiving, from a first terminal, a request for establishing a chat group without receiving an identifier of an existing social network contact; monitoring incoming requests for additional users to join the first chat group; while monitoring, detecting a request from a second terminal to obtain information of other terminals located around the second terminal; in accordance with the request from the second terminal and in accordance with a determination that the second terminal and the first terminal are located within a preset distance, requesting authentication information corresponding to the first chat group; receiving the authentication information from the second terminal, wherein the authentication information is obtained by the second user independently of the server of the social network platform; and in accordance with a determination that the authentication information is correct, establishing the first chat group including the first user and the second user.

A method and system for group-oriented encryption and decryption that supports the implementation of the designation and revocation functions of decryption users in a large-scale group. During the encryption, the system acquires a corresponding aggregate function according to an encryption mode; acquires any selected subset S and public parameters, and outputs an aggregate value of the subset S; generates a ciphertext of to-be-transmitted information according to the public parameters, a to-be-transmitted message and the aggregate value; acquires the encryption mode and the subset S comprised in the received ciphertext, operates the subset S and an identity of a current decryptor according to the encryption mode, and outputs a new subset S′; acquires an aggregate function corresponding to the encryption mode during the decryption; outputs an aggregate value of the new subset S′; and decrypts the received ciphertext according to the public parameters and the aggregate value, so as to obtain the to-be-transmitted information.

Some aspects of the present disclosure involve the recording, processing and playback of audio data corresponding to conferences, such as teleconferences. In some teleconference implementations, the audio experience heard when a recording of the conference is played back may be substantially different from the audio experience of an individual conference participant during the original teleconference. In some implementations, the recorded audio data may include at least some audio data that was not available during the teleconference. In some examples, the spatial characteristics of the played-back audio data may be different from that of the audio heard by participants of the teleconference.

A method, apparatus, and computer readable medium are provided for maximizing consumption of broadcasts by a producer. An example method includes receiving selection of a total number of time slots to use for scheduling broadcasts, and receiving information regarding the producer's followers. The example method further 5 includes identifying, by a processor and based on the received information, discount factors associated with the producer's followers, and calculating, by the processor and based on the received information, a predicted number of competitor broadcasts during each time slot of the total number of time slots. Finally, the example method includes determining, by the processor and based on the discount factors and the predicted 10 number of competitor broadcasts during each time slot, a number of broadcasts for the producer to transmit in each time slot of the total number of time slots.

A social networking server receives a request from a member of an organization to configure a targeted update for the organization. The targeted update may be intended for a particular group of members of a social network service. The social networking server may provide various follower dimensions to associate with the targeted update, where each of the follower dimensions include one or more selectable attributes. When the social networking server receives a request for an organization's webpage from a member of the social network service, the social networking server may compare member attributes of a member profile associated with the member with the follower dimension attributes associated with the targeted update. The social networking server may provide the targeted update for display with the webpage of the organization based on the member attributes satisfying at least one follower dimension attribute associated with the targeted update.

A system and method to provide multimedia services to consumption end devices like set-top boxes and legacy phone and tablet devices that are incompatible to receive the multimedia service directly. These consumption devices interact with devices that provide multimedia service. Further, the present disclosure discloses mechanisms where an end consumption device can connect to a device like LTE connectivity device and obtain eMBMS multimedia services.

A unified visualization interface is disclosed. One example is a system including an association module, a multicasting module, a data sharing module, and a unified visualization interface. The association module associates an identified event in a first visualization system with a visualization function. The multicasting module stores event data related to the identified event and the associated visualization function in a shared data source, and multicasts the identified event to a second visualization system. The data sharing module associates the event data with characteristics of the first visualization system, and shares, in response to the multicast of the identified event, the shared data source with the second visualization system. The unified visualization interface automatically invokes, without software changes, the second visualization system in response to the multicast of the identified event, the invoking based on the shared data source including the characteristics of the first visualization system.

System and methods are provided for receiving identification information from remote user devices associated with users. The identification information serves to obtain corresponding stored user profiles. Primary communication channels are generated for each user based upon their profiles. Each such primary channel is limited to communication with, and facilitates electronic communication between, a single corresponding enterprise data source, and users. For each respective primary channel in a subset of the primary channels of a first user, a corresponding plurality of sub-channels is generated based upon their profile. Each such plurality of sub-channels forms a corresponding hierarchical tree with the corresponding primary channel as root node and the sub-channels as child nodes. A sub-channel in a hierarchy of sub-channels enables secure bidirectional communication between (i) the remote user device associated with the first user and (ii) the enterprise data source associated with the primary channel of the hierarchy.

For logical multicasting in overlay networks, at a data processing system, an original unicast packet is received from a first component in a first computing node in an overlay network. To cause multicasting in the overlay network the received original unicast packet was unicast by the first computing node only to the data processing system, and a multicast data structure for the overlay network is maintained only by the data processing system, the multicast data structure containing information of each receiver that is configured to receive unicast packets during logical multicasting in the overlay network. From a set of subscriber receivers in the multicast data structure, a subset of the subscriber receivers is selected. A copy of the original unicast packet is unicast to each subscriber receiver in the subset.
