A new watermarking scheme based on Daubechies wavelet and chaotic map for quick response code images

Abstract

The world is evolving due to fast transmission of digital information in the forms of different digital contents over numerous online web applications. The transmission of information over social media is at its peak. The advanced means of different digital applications make our lives quite easy but it added more sensitivity to our digital information which can accessed through internet. In the advanced digital era, the protection of digital information and intellectual properties of any organizations is one of the vital problems in technologically advanced ages. To protect the illegal access and duplication of any digital information over insecure communication is fall in the copyright protection techniques. The digital watermarking which is one of the fundamental classes of information hiding techniques that can be used to protect the ownership of any digital contents. Generally, the digital contents cannot be altered in information hiding schemes but secret information is embedded in information carriers. The perception of this article is to design a new digital watermarking scheme which uses multi-layer of information security algorithms. We have utilized chaotic logistic map in order to generate a nonlinear component of block cipher and then applied the suggested substitution box (S-box) in order to encrypt a quick response code (QR-code). Moreover, our innovative suggested watermarking scheme uses Daubechies wavelet transform which is an efficient multi-determination frequency domain for the insertion of encrypted digital logo in the form of QR-codes. We have used different strength analysis which clearly authenticates the validity of our anticipated watermarking scheme.
