Mobile device digital communication and authentication methods
First Claim
1. A method for non-intrusive bi-directional visual communication, comprising:
- displaying on a screen a series of temporary noise dots deviating from an ordinary display on the screen, the temporary noise dots comprising controlled low-level noise on the screen and the temporary noise dots having a time duration sufficiently short to prevent a user from effectively viewing the temporary noise dots;
capturing the series on the screen with an image capture device; and
determining a difference between the ordinary display and the temporary noise dots.

Abstract
Embodiments of the present invention provide various approaches for mobile device intercommunication (e.g., digital) as well as various authentication methods. In one embodiment, the present invention provides direct line-of-sight visual digital communication between mobile devices for controlled security. In another embodiment, the present invention provides direct contact motion-based digital communication between mobile devices for controlled security. Embodiments of the present invention also provide various authentication methods. One such example relates to secure authentication code exchange with subsequent digital communications in one or more channels. In another example, human-readable information is used along machine-readable digital codes (e.g., quick response (QR) codes to verify visual codes. Still yet, embodiments of the present invention provide non-obtrusive visual codes that maintain a user'"'"'s access to a mobile device screen.

4. A method for non-intrusive bi-directional visual communication, comprising:
-
displaying on a screen a series of temporary noise dots deviating from an ordinary display on the screen; capturing the screen with an image capture device; determining a difference between the ordinary display and the temporary noise dots; communicating a proximity authentication code from a first device associated with the screen to a second device associated with the image capture device via the series of temporary noise dots; comparing, responsive to the communicating, the proximity authentication code at the second device against a library of valid codes; authenticating the proximity authentication code based on the comparing; communicating a data abstract between the first device and the second device; determining at least one communication channel for transferring data between the first device and the second device based on the data abstract, the determining comprising adjusting a communication setup of the communication channel, wherein the adjusting the communication setup comprises negotiating a protocol; transferring data via the adjusted communication setup of the communication channel; and acknowledging transfer of the data via a data acknowledgement code. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
