“…In 1995, Naor and Shamir proposed four types of (k, n)-threshold SSSs [3], but their schemes exhibited the expansion problem with each share. Some studies [3][4][5][6][7][8][9] related to VC have exhibited the common problem of pixel expansion. Pixel expansion occurs when each share is larger than the input secret image.…”

Visual cryptography (VC) encrypts a secret image into n shares (transparency). As such, we cannot see any information from any one share, and the original image is decrypted by stacking all of the shares. The general (k, n)-threshold secret sharing scheme (SSS) can similarly encrypt and decrypt the original image by stacking at least k (≤ n) shares. If one stack is fewer than k shares, the secret image is unrecognizable. Another subject is progressive visual secret sharing, which means that when more shares are progressively stacked, the combined share becomes clearer. In this study, we constructed an advanced scheme for (k, n)-threshold SSS that can be encrypted in VC for any positive integers n ≥ k ≥ 2 through the method of combination, and the size of each share is the same as that of the original image. That is, no pixel expansion is required. Our scheme is novel, and the results from the theoretical analysis and simulation reveal that our scheme exhibits favorable contrast to that of other related schemes.

As we know, the Internet is widely used to share and retrieve information. Shares large amounts of information that need to be protected from unauthorized access. In it the secret colour image of any format in which the text is hidden is divided into multiple pieces. The individual slice does not give the impression of an original secret image. The original image appears after the pieces are stacked. These pieces can be sent to the desired receiver via the Internet. The pieces look like pictures so they indirectly invite hackers. The pieces are encrypted and securely transferred to prevent hacker interference in this particular way.

“…Later Threshold Visual Cryptography Schemes with Specified Whiteness Levels of Reconstructed Pixels by Philip A Eisen and Douglas R Stinson [2] introduced a method known as a threshold visual cryptography scheme (VCS), has the benefit of requiring no cryptographic computation on the part of the decoders. This new definition motivates an examination of minimizing pixel expansion subject to fixing the VCS parameters ">h and ">l. New bounds on pixel expansion are introduced, and connections between these bounds are examined.…”

Gathering intelligence plays a vital role in safeguarding a nation from insurgency and offensive military strikes from hostile countries. It is recommended to provide logistic support to the armed forces constantly thereby keeping them informed of the ground situation and alert them in advance to acquire an advantage. Surveillance is achieved via satellite imaging. Such confidential images captured are to be transmitted in real time securely to avoid any third party from interpreting them. This can be obtained by utilizing Visual Cryptography. Visual Cryptography secret image sharing ensures security of the transmitted information by splitting a secret image into n shares which are owned by n participants to prevent the secret from accidentally being lost. Existing algorithms provide solutions for problems such as secret information leaking from shares, attack on share images and large share image issues but their time complexity is still debatable. Therefore, the proposed Quadri directional search algorithm technique can be implemented for encrypting the information.
