Secured Picode: Using Visual Cryptography

In this paper, we propose a new technology which combines the visual cryptography with a picture embedding pictode for the security of information. Hence the paper combines both the advantages of the modified visual cryptography and improved picture embedded 2D barcode. Actually, there are two methods used to introduce confidentiality and security when visual data are transmitted through unsecured channels: data hiding and visual cryptography. Data hiding usually tries to embed data in digital media and transmit it in an imperceptible way so that the confidential messages is send securely and with visual cryptography the original input is shared between a set of participants by a secret image holder. Visual cryptography is a method of protecting the image-based secrets that has a computation free decoding process. The scheme provides an efficient way to hide the natural image among different shares. The two-dimensional barcodes have been widely used as an interface to connect potential customers and advertisement contents. However, the appearance of a conventional 2D barcode pattern is often too obtrusive for integrating into an aesthetically designed advertisement. Citation:Tharani.
