Abstract
A technique for preventing malicious observance of private information includes receiving an instruction of entering a mode of inputting private information; determining a correspondence between actual inputs and expected inputs; receiving an actual user input; and converting the actual input into an expected input as private information inputted by the user according to the correspondence. This security technique can prevent discovery of the private information of a user through observation.
