QR Code Steganography Mechanism With High Capacity

In every world,every time there is great data on the Internet,people publish various forms of information,Such as images,video,and voice,digital audio,etc.,Information in the Internet era,we enjoy the convenience of information at the same time,also a certain security risk.Sometimes in the online exchange of time when there is a risk In order to solve the Security problem of information,two-dimensional code is being studied by more and more.Abstract--QR code is the commonly used twodimensional(2D)barcode recently with the advantages of larger QR content and error correction capability.General QR reader can scan the contents of the QR code.When the content of the QR code is secret information,the information security becomes important.To protect the security of secret information.The new proposed method can embeddable secret information into the content of QR code.The information is hidden in the least significant bit,the use of the least significant bit on the two-dimensional code picture is the smallest,so it will not affect the two-dimensional code visual effects.In this new proposed method,the QR content can be easily decoded by a QR reader.Because general browsers can read the QR content,so few people can decoded the QR code can scanning to the secret information.The new algorithm to achieve the function,that is,the use of the least significant bit of the XOR operation,the results obtained with the confidential information bits,change the least significant bit or result so that the results obtained with the same confidential information bits.This secret information is hidden in the two-dimensional code.This is the new two-dimensional code picture and the previous picture is basically the same,no change in the visual.The new method is based on the error correction of the QR code,the QR code reduced distortion,and increases the capacity of hiding secret information.The mechanism based on module so the new method is more efficient.The new way can be applied to mobile phones and mobile devices.
