  • Publication number: 20190333060
    Abstract: A method of verifying identity information is performed at a computer server using a social networking application. The computer server receives an identity verification request from a first terminal. The first terminal is associated with a first account of the social networking application and the identity verification request includes information of a verification code and a second account of the social networking application. The computer server then forwards information of the verification code to a second terminal associated with the second account of the social networking application. Upon receipt of a response from the second terminal, the computer server establishes a relationship between the first account and the second account after verification of the response from the second terminal using the verification code such that the second terminal can interact with the first terminal through the social networking application.
