Abstract: An account information obtaining method performed at a terminal includes the following steps: in response to a request of a current user of the terminal, invoking a social networking application running on the terminal to obtain biological information of a target user; extracting biological feature data from the biological information, and sending the biological feature data to a server; receiving, from the server, account information of the target user whose at least one associated biological feature data sample matches the biological feature data, and displaying the account information on the terminal; and in response to a selection of the account information by the current user of the terminal, adding the account information to a contact list of the current user's account at the social networking application so that the current user can communicate with the target user directly.

Abstract: An account adding method is performed by a social networking application running at a mobile terminal when communicating with a second terminal (e.g., using a chat session). The method includes: recording voice information from the second terminal using the social networking application; extracting character string information and voiceprint information from the voice information; sending the character string information and the voiceprint information to a server; receiving an account that matches the character string information and the voiceprint information and that is sent by the server; and adding the account to a contact list of the social networking application. For example, the social networking application is started before starting a telephone call with the second terminal and the voice information is recorded during the telephone call.
