Abstract
A method for secured entry of personal data is disclosed. This method comprises for each item of personal data a first step of presentation of a virtual keyboard comprising keys and a first cursor, followed by a step of selection of a key corresponding to the item of personal data wherein the virtual keyboard also comprises at least one dummy cursor and wherein the position on the virtual keyboard of the at least one dummy cursor depends on the position of the first cursor. A device for secured entry of personal data configured to implement the method is further disclosed.
Claims8
A method for secured entry of personal data comprising, for each item of personal data:
- a) generation, by a computing device, of a user interface including a virtual keyboard comprising keys, a first cursor and at least one dummy cursor, the at least one dummy cursor being generated to overcome a “key-logger” attack,
- b) selecting, by the computing device upon receipt of a user command from a peripheral device, a key corresponding to said item of personal data,
- controlling a position on the virtual keyboard of said at least one dummy cursor, by the computing device, based on a position of the first cursor on said virtual keyboard wherein movement over the virtual keyboard of said at least one dummy cursor depends on movement of the first cursor;
- and
- wherein a speed of the movement over the virtual keyboard of said at least one dummy cursor depends on a speed of the movement of the first cursor and wherein a position of the keys on the virtual keyboard presented for two successive items of personal data is a result of a random permutation.
A device for secured entry of personal data comprising:
- a) a computing device that generates a user interface including a virtual keyboard comprising keys, a first cursor and at least one dummy cursor, the at least one dummy cursor being generated to overcome a “key-logger” attack,
- b) a screen for display of the user interface;
- c) a pointing device for selection, upon receipt of a user command, of a key corresponding to an item of personal information,
- wherein a position at which the at least one dummy cursor is displayed on the virtual keyboard is controlled based on a position of the first cursor on the virtual keyboard and wherein movement over the virtual keyboard of said at least one dummy cursor depends randomly on movement of the first cursor;
- and
- wherein a speed of movement over the virtual keyboard of said at least one dummy cursor depends on a speed of the movement of the first cursor and a position of keys on the virtual keyboard presented for two successive items of personal data is a result of a random permutation.
A device for secured entry of personal data comprising:
- a computing device including a processor that generates a user interface on a screen including a virtual keyboard comprising keys, a first cursor and at least one dummy cursor, the at least one dummy cursor being generated by the processor to overcome a “key-logger” attack, the computing device including an input for receiving a user command, from a pointing device, of a key corresponding to an item of personal information,
- wherein a position at which the at least one dummy cursor is displayed on the virtual keyboard is controlled by the processor based on a position of the first cursor on the virtual keyboard and wherein movement over the virtual keyboard of said at least one dummy cursor is controlled by the processor and depends on movement of the first cursor;
- and
- wherein a speed of movement over the virtual keyboard of said at least one dummy cursor is controlled by the processor and depends on a speed of the movement of the first cursor and a position of keys on the virtual keyboard presented for two successive items of personal data is a result of a random permutation.
