Abstract: A method of mobile optical recognition involves equipping authorized parties with a tag capable of generating a light spectrum signal. A step is taken of sending from a mobile device having a scanner a signal interrogating the tag. A further step is then taken of capturing with the scanner an image of a generated light spectrum signal generated by the tag in response to interrogation by the mobile device. A final step involves comparing the generated light spectrum signal with an anticipated light spectrum signal stored in a database to verify authenticity.

Abstract: There is provided a method to activate and restict control of a device. A first step involves positioning a secondary device on a human body which generates an authorization key. A second step involves using the human body as a local transmitter to transmit the authorization key from the secondary device to the device which is to be activated and controlled.
