Two-dimensional barcode to avoid unintentional scanning
First Claim
Patent Images
1. A system for reading an encoded message, comprising:
- a scanning device configured to read the encoded message; and
an article having a two-dimensional barcode disposed thereon, the barcode comprising;
the encoded message in a data area of the two-dimensional barcode, wherein the two-dimensional barcode employs a two-color encoding scheme,a quiet zone surrounding the data area that enables the scanning device to locate the data area,a finder pattern in each of three corners of the data area for allowing the scanning device to determine an orientation of the barcode for reading the barcode, anda finder pattern in a selected region in a fourth corner of the data area configured to disable decoding of the encoded message at the scanning device by preventing the scanning device from determining the orientation of the barcode for reading the barcode, wherein occluding the finder pattern in the selected region from a purview of the scanning device while the scanning device scans the barcode enables the scanning device to orient the barcode for reading and to read the encoded message in a non-occluded region of the barcode.

Abstract
A method of disseminating a message is disclosed. The message is encoding in a barcode. A selected region of the barcode is damaged so as to hinder decoding of the message at a scanning device. The damaged region of the barcode may be occluded from the scanning device in order to enable the scanning device to read the barcode and the message therein.

10. A system, comprising:
-
a scanning device configured to read an encoded message; and an article having the encoded message, the article including; a QR code disposed on the article that provides a first signal that includes the encoded message in a data area of the QR code and a quiet zone surrounding the data area that enables the scanning device to locate the data area wherein the QR code employs a two-color encoding scheme, a finder pattern in each of three corners of the data area for allowing the scanning device to determine an orientation of the QR code for reading the QR code, and a second signal in a fourth corner of the data area of the QR code configured to disable reading of the encoded message at the scanning device by preventing the scanning device from determining an orientation of the QR code for reading the QR code when the second signal is read along with the finder patterns, wherein occluding the second signal from the purview of the scanning device and leaving the first signal non-occluded while scanning the QR code with the scanning device enables the scanning device to determine the orientation of the QR code for reading the QR code, obtain the first signal and read the encoded message from the obtained first signal. - View Dependent Claims (11)

12. A system for reading an encoded message, comprising:
-
a scanning device for reading the encoded message; and an article having the encoded message disposed thereon, comprising; a data area of a QR code having the encoded message, wherein the QR code includes a two-color encoding scheme, a quiet zone surrounding the data area that enables a scanning device to locate the data area, a finder pattern in each of three corners of the data area for allowing the scanning device to determine an orientation of the QR code for reading of the QR code, and a finder pattern in a fourth corner of the data area configured to disable reading of the encoded message by the scanning device by preventing the scanning device from determining the orientation of the barcode for reading the barcode, wherein occluding the finder pattern in the fourth corner from purview of the scanning device while scanning the QR code enables the scanning device to determine the orientation of the QR code for reading the QR code and to read the encoded message in a non-occluded region of the QR code. - View Dependent Claims (13, 14, 15, 16)
