This chapter discloses an invention related to methods and systems to provide secure and custom information exchange code for the users of haptic or kinesthetic communication devices in a variety of applications. The proposed information exchange codes are named as "haptic codes," where it maps several touch interactive locations into a single information exchange code. Thus, the proposed haptic code facilitates the representation of different notions to unique information exchange character/digit/symbol. A method has been invented to design eight such codes from the intuitive touch gestures (ITG) of user, each of which uses double-touch on arbitrary location within the touch pad/screen without shifting hand position on every touch. Hand position may or may not be the same after the generation of every ITG. Haptic codes are made secure by incorporating a new cryptographic system, which employs polar graph for encoding and decoding such locations using polar curves as shareable keys. Therefore, haptic codes can be exchanged for secure communication and read by devices that supports to touch.
FIELD OF INVESTIGATIONThe present invention relates to development of information exchange code for short and secured communication using human finger gestures on haptic or kinesthetic communication device. These new information exchange codes are named as custom
