<p>Disclosed are a secure input method and system. The method comprises: when secure input is required to be performed, starting a virtual machine mode of a central processing unit; in the virtual machine mode, switching an operating system to a non-root mode, and switching a virtual machine manager allocated for a secure input protection program to a root mode; the operating system receiving input data of a user, and transmitting same to the virtual machine manager; the virtual machine manager encrypting and saving the input data for a legal program to invoke, and the virtual machine manager generating false input data and returning the false input data to the operating system; and when it is determined that the secure input of the user has ended, closing the virtual machine mode of the central processing unit. The solution can not only dispense with the change of the usage habit of the user and the configuration of additional hardware devices, but can also more effectively prevent Trojans from intercepting or tampering the content input by the user, thereby improving the accuracy and security of information.</p> |
