Steganography Using Visual Cryptography

Front Cover

This work is authored by Pratheek Praveen Kumar along with Ruchir Bhgat and Shiksha Suvarna, all three Telecommunications Engineers. 

Digital Watermarking is the process of irreversibly embedding information into a digital signal. The signal may be audio, pictures or video. There are two types of Watermarking, Visible Watermarking and Invisible Watermarking. In Visible Watermarking, the information is visible in the picture or video. Typically, the information is text or a logo which identifies the owner of the media. Example of Visible Watermark is when a television broadcaster adds its logo to the corner of transmitted video. In Invisible Watermarking, information is added as digital data to audio, picture or video, but it cannot be perceived as such (although it is possible to detect the hidden information). 

Digital Watermarking schemes are widely being used as potential solution for ownership protection. The Watermarking algorithms in general, may be viewed as digital communication scheme for imperceptible transmission of an auxiliary message through cover image. Several software implementations of the proposed algorithms are available, but very few attempts have been made for the property of robustness and they are not able to provide the good visual Recovery Watermark Image (IWD) as user aspect. This is accomplished by spreading one watermark bit over many samples of the Cover data using a modulated spreading sequence. 

This is a study of this technology.

About the author (2019)

Born in Bangalore as son of Shree Praveen Kumar and Smt. Jayashree, presently I reside with parents in Bangalore. I completed my engineering course in Telecommunications Engineering from the reputed R.V. College of Engineering, Bangalore. I did my ICSE and ISC with distinction from the prestigious Bishop Cotton Boys’ School, Bangalore.


I authored four books including an anthology of English Poems, “CALM REFLECTIONS”, published in the USA in 2009. I am also credited with several first prizes in national level essay competitions, as well as in inter-college essay competitions.


A cricket enthusiast, I love horse riding, tennis, billiards, cycling and football. I stood first in Arm Wrestling competition held in R.V.College of Engineering, and stood first in Information Technology competition held in Bishop Cotton Boys’ School. 


I am a modest, hard-working person, and set firm goals for myself. Once defined my benchmarks, I take steps to achieve those goals. I think positively, and love to work hard to achieve challenging tasks, and take responsibility for works assigned to me, and try to improve myself to take on the next challenge. I enjoy succeeding in an environment of growth and excellence, and look to constantly improve my professional and human skills.
