Secure Watermarking to Protect Colour Images on Social Media from Misuse

ABSTRACT

Nowadays the use of electronic media is increasing very rapidly. Especially during the pandemic situation of COVID-19, it has been increased very fast. During lockdown people shared their images on social media, IT industries are working online and people are sharing data to each other in online mode, i.e. in multimedia mode. Multimedia data contains text, video, audio and software, etc. Social media is one of the big platforms to share their contents in multimedia form. Every person is sharing his/her data without knowing about intruders. Intruders can misuse the data posted on web. Social media is the biggest platform for scammers. Hence, the security of digital content is the major issue before us. Various researchers are doing work in this area. Watermarking technique is the most usable protecting techniques from misuse of digital information. The proposed technique in the paper using secure watermarking is useful to protect colour images using unique ID Aadhar number, Discrete Wavelet Transform and Singular Value Decomposition. The experimental results show that this technique is robust and can be used to claim the authenticity during any legal issue. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
