Method and system for processing operation request

A method for processing an operation request, comprising:

• detecting by a terminal an operation request from a user, and sending by the terminal an operation request message of the user to a smart card;
• receiving by the smart card the operation request message output from the terminal, signing by the smart card the operation request message according to a preset signature generating strategy to obtain a signature message, generating by the smart card a joint password according to a password generating strategy pre-stored locally, adjusting by the smart card a content of the joint password according to a preset joint password adjustment strategy to obtain an adjusted joint password, and sending by the smart card the adjusted joint password and the signature message to the terminal;
• outputting by the smart card a prompt message about the joint password, if the smart card detects that the smart card is disconnected from the terminal after the terminal obtains the signature message and the adjusted joint password;
• receiving by the terminal the joint password corresponding to the prompt message, using the joint password corresponding to the prompt message as a password to be verified, notifying a verification device by the terminal to verify the signature message and the password to be verified, and triggering by the verification device a procedure responding to the operation request if the signature message and the password to be verified are successfully verified.

A system for processing an operation request, wherein the system comprises a terminal, a smart card and a verification device, the terminal comprises a first sending module and a notifying module, the smart card comprises a first generating module, a second generating module, an adjusting module, a second sending module and an output module, and the verification device comprises a trigger module, in which,

• the first sending module is configured to send an operation request message of a user to the smart card after detecting an operation request from the user;
• the first generating module is connected with the first sending module and configured to generate a signature message by signing the operation request message according to a preset signature generating strategy after obtaining the operation request message output from the terminal;
• the second generating module is configured to generate a joint password according to a password generating strategy pre-stored locally;
• the adjusting module is connected with the second generating module and configured to adjust a content of the joint password according to a preset joint password adjustment strategy to obtain an adjusted joint password;
• the second sending module is connected with the first generating module and the adjusting module respectively and configured to send the adjusted joint password and the signature message to the terminal;
• the output module is configured to output a prompt message about the joint password, if the smart card detects that the smart card is disconnected from the terminal after the terminal obtains the signature message and the adjusted joint password;
• the notifying module is configured to use the joint password corresponding to the prompt message as a password to be verified after receiving the joint password corresponding to the prompt message, and to notify the verification device to verify the signature message and the password to be verified;
• the trigger module is configured to trigger a procedure responding to the operation request if the signature message and the password to be verified are successfully verified.
