Preventing malicious observance of private information

摘要

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.

主权项

1. A computer program product for preventing data exposure, the computer program product comprising:
a non-transitory, computer readable storage medium having computer usable program code embodied therewith, the computer usable program code comprising a computer usable program code to, present, via a graphical user interface, a plurality of input fields and visible input cues for user input, wherein one or more pairs of the visible input cues flank each of the plurality of input fields, wherein at least one of the visible input cues indicates one or more different directions for selecting the user input relative to a flanked input field, and wherein one of the visible input cues is associated with an expected input value that differs from the one of the visible input cues; determine a correspondence between the one of the visible input cues and the expected input value before the one of the visible input cues is selected, wherein the correspondence indicates how the one of the visible input cues differs from the expected input value; generate an invisible output that indicates the correspondence between the one of the visible input cues and the expected input value; detect a selection of the one of the visible input cues via the graphical user interface; and use, as the user input, the expected input value instead of the one of the visible input cues in response to the selection of the one of the visible input cues.
