A client terminal sends a communication request to a server. The server generates at least one digit code according to a first preset rule. The server sends information including the at least one digit code to the client terminal. The client terminal generates at least one input box, a number of which corresponds to a number of the at least one digit code, detects an input event of the at least one input box, and obtains data of the at least input box when the input event occurs. The client terminal sends the data of the at least one input box as at least one verification data to the server. The server compares the digit data corresponding to the at least one digit code with the verification data and sends a successful information code to the client terminal when the two are the same. The techniques improve password security. |
