User identity verification method and system, and verification server

A server comprising:

• one or more processors;
• and
• memory storing computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
• receiving an identity verification request from a first client terminal of a user;
• determining a first communication number according to the identity verification request;
• generating a temporary communication number for the first communication number;
• recording the first communication number and the temporary communication number as first data;
• returning the temporary communication number to the first client terminal;
• receiving a call request to the temporary communication number from a second client terminal;
• determining a second communication number corresponding to the call request and the temporary communication number as second data;
• verifying that the first data matches with the second data;
• and
• selecting a content of a prompt audio message to be played at the second client terminal according to a security level of an identity verification corresponding to the identity verification request, the selecting including:
• in response to determining that the security level of the identity verification is a first level, instructing to play a default prompt audio message and determining that the identity verification succeeds after the default prompt audio message is played;
• in response to determining that the security level of the identity verification is a second level, instructing to press a corresponding key;
• and
• in response to determining that the security level of the identity verification is a third level, instructing to input a corresponding numerical string or character string.

One or more computer-readable media storing computer-readable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• receiving an identity verification request sent from a client terminal of a user;
• determining a first communication number according to the identity verification request;
• generating a temporary communication number for the first communication number;
• recording the first communication number and the temporary communication number as first data;
• returning the temporary communication number to the client terminal;
• receiving a call request to the temporary communication number, the call request associated with a second communication number;
• determining the second communication number and the temporary communication number as second data;
• verifying that the first data matches with the second data;
• selecting a security level of an identity verification corresponding to the identity verification request, the selecting including:
• in response to determining that the user is in a normal state, selecting a first level verification;
• in response to determining that the user is in an abnormal state, selecting a second level verification;
• and
• in response to determining that the user is flagged, selecting a third level verification;
• and
• selecting a content of a prompt audio message to be played according to the security level of the identity verification.
