The invention provides an information processing method. The information processing method is applied to a terminal that comprises a plurality of operating systems. The information processing method comprises: upon receiving an instruction of copying data information in an arbitrary operating system to a specified operating system among the plurality of operating systems, acquiring a target entering key of the specified operating system; and after copying the data information to the specified operating system, encrypting the data information in the arbitrary operating system by using the target entering key of the specified operating system, or not displaying the data information in the arbitrary operating system again. The technical solution guarantees that data are not lost and also guarantees that data are not easy to divulge. The invention also provides a terminal and a nonvolatile machine-readable medium.
