Abstract
The present invention is directed to a touch screen system and method for entry of encrypted and non-encrypted information. The system and method comprise a sensing means for detecting the coordinates of a touch on the touch screen device, a toggling means for toggling between encryption and non-encryption mode, and a processing means for encrypting data associated with the coordinates of the touch and transmitting the encrypted or non-encrypted data to a remote processor.
Claims27
A system for selectively generating encrypted or non-encrypted data within a touch screen device and transmitting the data to a remote processor via a data bus, comprising:
- (A) sensing means for detecting the coordinates of a touch on the touch screen device;
- (B) toggling means for toggling between an encryption and non-encryption mode, said toggling means responsive to a mode selection communicated via said data bus;
- and
- (C) a processor for:
- (i) encrypting data associated with the coordinates of the touch and transmitting the encrypted data to the remote processor via said data bus, if the toggling means is in the encryption mode;
- and
- (ii) transmitting data associated with the coordinate of the touch in an unencrypted format to the remote processor via said data bus, if the toggling means is in the non-encryption mode.
A system for selectively generating encrypted or non-encrypted data within a touch screen device, comprising:
- (A) a remote processor for receiving the encrypted or non-encrypted data via a data bus;
- (B) sensing means for detecting the coordinates of a touch on the touch screen device;
- (C) toggling means responsive to a mode selection command received via said data bus from the remote processor, for toggling between an encryption and non-encryption mode;
- and
- (D) a processor for:
- (i) encrypting data associated with the coordinates of the touch and transmitting the encrypted data to the remote processor via said data bus, if the toggling means is in the encryption mode;
- and
- (ii) transmitting data associated with the coordinates of the touch in an unencrypted format to the remote processor via said data bus, if the toggling means is in the non-encryption mode.
A method for selectively generating encrypted or non-encrypted data within a touch screen device and transmitting the data to a remote processor via a data bus, comprising the steps of:
- (A) detecting the coordinates of a touch on the touch screen device;
- (B) toggling between an encryption and non-encryption mode in response to a mode selection communicated via said data bus;
- (C) encrypting data associated with the coordinates of the touch and transmitting the encrypted data to the remote processor via said data bus, if the toggling means is in the encryption mode;
- and
- (D) transmitting data associated with the coordinate of the touch in an unencrypted format to the remote processor via said data bus, if the toggling means is in the nonencryption mode.
