Signals, images, emails, voice and videos, everything comes under screening
before or after it is communicated. Protecting the information is highly essential
especially in electronic communication which has become a stipulation in the
routine life of zillions. Since safeguarding has many literal connotations,
this study ntrates on one of them, privacy; technically secrecy or security.
From the family of Information security, the proposed method can pick out cryptography
and steganography to make this algorithm more secure and effective as well.
As far as Visual Cryptography is concerned, the primary terminologies here are
share, user and transparency. Its blend with steganography is worth mentionable
here as it forms a new platform in information security and secret sharing.
For embedding, Pixel Indicator (PI), Pixel Value Differencing (PVD) and OPAP
are used. With reference to Pixel Indicator, two methods are discussed here.
The effectiveness of the proposed method is assessed by calculating MSE and
PSNR and the outcomes are tabulated and compared with existing methods.
