Time-varying barcodes for information exchange
View Patent ↗Embodiments of the present invention provide time-varying barcodes for information exchange. Specifically, embodiments of the present invention provide a system and method for communicating information between electronic devices via a time-varying barcode image sequence. In a typical embodiment, information to be transmitted is divided into packets. A barcode image is generated from each packet. Each barcode image is displayed sequentially with varying display times based on the complexity of the barcode image. A second electronic device reads and decodes the barcode image sequence until the entire information is received.
1. A data communication device for communicating information via an image, said device comprising:
a display component configured to display an image sequence or authentication graphic on a display screen of the device;
a reader component configured to read an image sequence or authentication graphic;
a decoding component configured to decode an image sequence; and
a receiving component configured to receive an authentication graphic;
wherein at least one member of the image sequence differs from the other members with respect to a display specification, and wherein the reader component is further configured to sample a display to determine when the entire image sequence is received or the authentication graphic is displayed.
2. The data communication device of claim 1 , further comprising a second device comprising components to at least one of:
display an image sequence on a display screen of the second device and recognize a return authentication graphic by a camera; and
read an image sequence by a camera of the second device and display an authentication graphic on a display screen.
3. The data communication device of claim 2 , wherein the second device further comprises:
a display component configured to display an image sequence or authentication graphic on a display screen of the second device;
a reader component configured to read an image sequence or authentication graphic;
a decoding component configured to decode an image sequence; and
a receiving component configured to receive an authentication graphic.
4. The data communication device of claim 1 , wherein the image sequence and authentication graphic each comprises at least one of: a barcode, a quick response (QR) code, and a graphical image.
5. The data communication device of claim 1 , wherein the display specification is the amount of time each image in the sequence is displayed, based upon the complexity of the image.
6. The data communication device of claim 1 , wherein the display component further comprises an image generating component configured to generate the image sequence from the information, wherein the information is divided into a group of packets, each packet being encoded as an image, and each packet including redundancy information with respect to a different packet or error correction data information with respect to a different packet.
7. A method for providing a data communication device for communicating information via a time-varying image, comprising:
providing an electronic device, comprising:
a display component configured to display an image sequence or authentication graphic on a display screen of the electronic device;
a reader component configured to read an image sequence or authentication graphic;
a decoding component configured to decode an image sequence; and
a receiving component configured to receive an authentication graphic;
wherein at least one member of the image sequence differs from the other members with respect to a display specification, and wherein the reader component is further configured to sample a display to determine when the entire image sequence is received or the authentication graphic is displayed.
8. The method of claim 7 , further comprising providing a second electronic device, comprising components to at least one of:
display an image sequence on a display screen of the second device and recognize a return authentication graphic by a camera; and
read an image sequence by a camera of the second device and display an authentication graphic on a display screen.
9. The method of claim 8 , where the second device further comprises:
a display component configured to display an image sequence or authentication graphic on a display screen of the second device;
a reader component configured to read an image sequence or authentication graphic;
a decoding component configured to decode an image sequence; and
a receiving component configured to receive an authentication graphic.
10. The method of claim 7 , wherein the image sequence and authentication graphic each comprises at least one of: a barcode, a quick response (QR) code, and a graphical image.
11. The method of claim 7 , wherein the display specification is the amount of time each image in the sequence is displayed, based upon the complexity of the image.
12. The method of claim 7 , wherein the display component further comprises an image generating component configured to generate the image sequence from the information, wherein the information is divided into a group of packets, each packet being encoded as an image, and each packet including redundancy information with respect to a different packet or error correction data information with respect to a different packet.
