Adding and detecting bar code printed with ink invisible to human eye onto printed medium
First Claim
1. A method for adding a bar code printed with ink invisible to a human eye onto a printed medium having one or more images visible to the human eye, comprising:
- determining whether the images of the printed medium include an at least substantially uniform background in terms of color the at least substantially uniform background being contiguous, where the images are defined as other than blank space of the printed medium on which no portions of the images are located; and
,in response to determining that the images of the printed medium include the at least substantially uniform background in terms of color,printing the bar code on the at least substantially uniform background of the images of the printed medium using the ink invisible to the human eye, such that the bar code is superimposed on the at least substantially uniform background of the imageswherein the bar code encodes information relating to the images of the printed medium, and is scannable by a computing device to transmit the information to an electronic service such that the electronic service returns electronically encoded information relating to the images of the printed medium in return.

Abstract
A bar code is added to a printed medium having one or more images visible to the human eye. The bar code is printed with ink invisible to the human eye. The bar code as printed on the printed medium with ink invisible to the human eye is then detected, such as by a computing device like a mobile phone-type device. Information relating to the images on the printed medium is decoded from the bar code and transmitted to an electronic service. In return, electronically encoded information relating to the images on the printed medium is received from the electronic service and displayed.

7. A method for detecting a bar code printed with ink invisible to a human eye onto a printed medium having one or more images visible to the human eye, comprising:
-
capturing a first electronic version of the printed medium, the first electronic version corresponding to at least the images visible to the human eye; capturing a second electronic version of the printed medium, the second electronic version corresponding to at least the images visible to the human eye and the bar code invisible to the human eye; in response to determining that the bar code is superimposed over one or more parts of the images; removing effects of the images as captured within the second electronic version of the printed medium, from the bar code as captured within the second electronic version of the printed medium, using the first electronic version of the printed medium; decoding information relating to the images of the printed medium from the bar code as captured within the second electronic version of the printed medium and as from which the effects of the images as captured within the second electronic version of the printed medium have been removed; transmitting the information to the electronic service; receiving from the electronic service electronically encoded information relating to the images of the printed medium, in return; and
,displaying the electronically encoded information to a user. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A computing device comprising:
-
a capturing mechanism to capture a first electronic version and a second electronic version of a printed medium on which a bar code has been printed with ink invisible to a human eye and on which one or more images visible to the human eye have been printed, the first electronic version corresponding to at least the images visible to the human eye and the second electronic version corresponding to at least the images visible to the human eye and the bar code invisible to the human eye; an extraction mechanism to extract the bar code using the first and the second electronic versions of the printed medium; a communication mechanism to transmit information relating to the images of the printed medium as decoded from the bar code extracted from the first electronic version of the printed medium, the information transmitted to an electronic service, the communication mechanism also to receive electronically encoded information relating to the images of the printed medium from the electronic service in return; and
,a display mechanism to display the electronically encoded information relating to the images of the printed medium. - View Dependent Claims (15, 16, 17, 18, 19)
