Abstract: Embodiments of the present disclosure disclose a data response method, a terminal device, and a server. The method in the embodiments of the present disclosure includes: sending encrypted information to a terminal device; receiving a first honeypot character, the encrypted information, and user data from the terminal device; decrypting the encrypted information, to obtain a second honeypot character comprised in the encrypted information; determining whether the first honeypot character sent by the terminal device is the same as the second honeypot character decrypted from the encrypted information; and responding to the user data in response to the first honeypot character being the same as the second honeypot character.

Abstract: Aspects of the disclosure provide a device positioning method and apparatus. The apparatus includes processing circuitry. The processing circuitry is configured to determine at least one target user identifier (ID) that uses a target device to be positioned. The processing circuitry obtains a plurality of pieces of login information of the at least one target user ID where each piece of login information includes the respective target user ID, a device ID of a login device, and a login site. The processing circuitry further determines a target login site based on the plurality of pieces of login information, and positions the target device according to the target login site.

Abstract: Embodiments of the present invention disclose an identity authentication method. The method includes: receiving a request for identity authentication on a target user; sending identity-authentication information on the target user to one or more users in social-network-association with the target user; receiving feedback information from the users in social-network-association with the target user based on the identity-authentication information; and obtaining a result of identity authentication on the target user according to the feedback information from the users in social-network-association with the target user.
