SYSTEM, METHOD AND SERVER FOR INPUT VERIFICATION

摘要

A system, method and server for input verification is provided. The system includes a server (10) and a client (20). The server receives an authentication session sent by the client; selects a pre-set authentication mode and the corresponding resource randomly; generates authentication information and returns it to the client; obtains the input information of a user; compares the input with the authentication information to determine whether they match; if yes, the verification succeeds; otherwise the verification fails. The client sends an authentication session to and receives returned authentication information from the server, and sends the input information of the user to the server. The system, method and server for input verification can increase the difficulty of verification of being detected.
