Monitoring method, device and system of intelligent terminal payment environment

The invention discloses a monitoring method, device and system of intelligent terminal payment environment. One specific implementation way of the method comprises the following steps: receiving warning information about a payment-class application program, wherein the payment-class application program is positioned on an intelligent terminal; according to the warning information, sending the data running state information of the intelligent terminal in set time to a cloud server; receiving an application program control strategy which is sent from the cloud server and corresponds to the data running state information; and according to the application program control strategy, controlling the application program which causes the warning information to be exceptional on the intelligent terminal. After the warning information of the payment-class application program is received, the implementation way sends the data running state information in the set time to the cloud server, the cloud server obtains the application program control strategy according to the data running state information, so that the intelligent terminal controls the application program according to the application program control strategy, and the payment safety of the payment-class application program is improved.
