Abstract: This application discloses a method for implementing a secure transaction via a social network platform. A server receives a product purchase request from a client device, and the product purchase request includes product information, product server information and a user account identifier of the social network platform. The transaction server authenticates the product purchase request, and forwards the product purchase request of the corresponding product to the product server in an encrypted format. After receiving a confirmation message from the product server, the transaction server initiates a payment transaction between the user account and the product server. Further, after completing the payment transaction, the transaction server sends a payment completion message to the client device and the product server, respectively.

Abstract: A mobile device supports loading application-specific interfaces associated with the third-party application into a social networking application. The mobile device sends a third-party application identifier to a remote server, which returns a verification result. If positive, the mobile device activates the third-party application to generate an application-specific interface and loads the interface into the social networking application. After detecting a user request initiated through the interface, the mobile device sends the user request to the remote server, which performs a transaction with a third-party server accordingly and returns a response to the mobile device. In response, the mobile device deactivates the third-party application and replaces the application-specific interface with a display of an instant message corresponding to the response in the social networking application.

Abstract: When location information and a user Identification (ID) is received from a client terminal device of a user X, a grid Y, to which the location information belongs, is determined. The user ID and the location information of the user X is stored in a list of the grid Y. The grid Y is in a grid array obtained by dividing a surface of the earth into the grids and areas of the grids are the same. Users in the grid Y and other grids are searched. The grid Y and the other grids form an N-grid and the grid Y is a center of the N-grid. The users are ranked in an ascending order of distances between the users and the user X. The ranked user IDs and distances between the users and the user X are sent to the client terminal device of the user X.
