Abstract: The present disclosure disclose a video surveillance method performed at a sever. After sending first video information of a target video to a first client, the server receives reported information indicating a playback state of the target video from the first client. The reported information is obtained when the first client plays a video source file of the target video according to original address information and updates a first-frame playback time stored on a first location in a multi-dimensional table according to a first first-frame playback time in the reported information. The server then obtains, according to the first-frame playback time, a timeout waiting time in second video information and sends the second video information to a second client. When the second client does not play the target video in the timeout waiting time, the playback state of the target video is determined as unsuccessful playback.

Abstract: A method for data retrieval is described. Interface circuitry of an information processing apparatus receives a request for data retrieval from a database. The database stores content sharing information in a social network. The request includes a first user identifier and a first link identifier. The processing circuitry determines whether the first user identifier and the first link identifier are associated in the database as a consequence of a previous sharing of a first article corresponding to the first link identifier using the first user identifier. Further, when the first user identifier and the first link identifier are determined to be associated, the processing circuitry searches for a first message identifier in the database. The first message identifier identifies a first message that includes information of the previous sharing of the first article. The processing circuitry then retrieves the first message according to the first message identifier.

Abstract: Methods and devices for information transmission and in particular for payment transfer from a paying terminal to a selling terminal. In some embodiments, the paying terminal scans an encrypted image, such as a two-dimensional code, displayed on the selling terminal. The paying terminal decrypts the encrypted image to obtain payment information and sends a payment request to a remote server for processing. Security verifications can be conducted by the paying terminal or the server, wherein the server may generate processing results approving or denying the payment request. When the payment amount is greater than a preset value, additional verification can be carried out using, e.g., biometric information. The paying terminal and/or the selling terminal then display the processing results and the remote server completes the payment transfer.
