Abstract
A data input device including a keypad. The data input device includes at least one proximity sensor positioned within a housing formed in an element of the device forming a projection in the vicinity of the keypad, the proximity sensor being oriented toward the keypad, the proximity sensor delivering measurements; and a program for analysing the measurements, delivering information representative of the presumed presence of a spy device on the keypad when the measurements are higher than a predetermined threshold for a predetermined time period.
Claims9
A data input device comprising a keypad positioned at a bottom of a recess of said data input device, the device also comprising:
- at least one proximity sensor positioned within a housing formed in an element of said device forming a projection in a vicinity of said keypad, said element corresponding to a wall of said recess, said proximity sensor being oriented toward said keypad, said proximity sensor delivering measurements;
- and
- means for analysing said measurements, delivering information representative of a presumed presence of a spy device on said keypad when said measurements are higher than a predetermined threshold for a predetermined time period.
A method for detecting a spy device positioned on a keypad of a data input device, said method being characterised in that, since the keypad is positioned at a bottom of a recess of said data input device, it comprises the following steps:
- obtaining measurements delivered by at least one proximity sensor positioned within a housing formed in an element of said data input device forming a projection in a vicinity of said keypad, and oriented toward said keypad, said element corresponding to a wall of said recess;
- analysing said measurements;
- delivering information representative of a presumed presence of the spy device on said keypad when said measurements are higher than a predetermined threshold for a predetermined time period.
