Proposed method for analyze the QR code and detection of vulnerabilities

Abstract EN

A 2D matrix that is designed via keeping two points under consideration is QR code, in other words, it stores a large amount of data as compared to 1D barcodes.

A Denso-Wave Corporation in Japan has been developed the QR code; the various marker of QR codes over traditional barcodes owns a large storage capacity, read faster, 360-degree reading, printing of small size, correction of error, and supports more languages.

The use of QR codes has been expanding over the world because of these benefits.

This paper tries to highlight the characteristics, working, significance, and vulnerabilities of the QR codes.

After applying the proposed method, the irrelevant positions were detected, then it was removed without any effect on the QR code reading, and these positions are used to hide text or image; indicating that the proposed new method has shown some important characteristics which will affect the security and confidentiality of the QR-code.
