“…According to this strategy, a single secret image (SI) is divided between two shares thus fixing these dual share SIs. The advantage of a VC is to divide an image into a collection of arbitrary share that completely reveals any data for the top category of SI 29,30 . The substantial element of this mechanism is that the image is decoded employing the human visual framework with any unpredictable calculations.…”

Visual cryptography (VC) is a secret sharing cryptographic technique, which permits visual information that is encrypted in such a way that the decrypted information shows the visual image. Security is the common problem that arises in the general VC technique. To secure the visual information, an effective method is proposed using a developed sailfish invasive weed optimization (SIWO) algorithm. At first, the grayscale image is shared with multiple parties, and here the shared images are encrypted and decrypted to reconstruct the original image back. The key generation is done using the developed SIWO-based data sharing approach. Here, the developed approach offered the peak signal-to-noise ratiof 34.870 and 33.711 dB for Lena and Cameraman images, respectively, and it attains better performance in terms of secret image sharing.

“…There are mainly two types of SIS: Visual Cryptography (VC) [13], [14], and polynomial interpolation based SIS schemes [15], [16]. The human visual system is used in the first type of schemes and there are no complicated calculations used during the recovering phase.…”

Secret Image Sharing (SIS) plays an important role in the field of information security. At present, from the perspective of image restoration, SIS schemes are roughly divided into two categories: traditional threshold SIS schemes and Progressive SIS (PSIS) schemes. The former provides an all-ornothing recovery mode in image reconstruction phase. If one of these shadows is damaged or lost, the reconstruction will fail. In contrast, the latter can present the original image progressively during the reconstruction phase. In this paper, a PSIS scheme based on semantic segmentation is proposed, where only specific objects or sensitive areas in the image are shared. After simple processing, the remaining background images can be publicly transmitted on insecure channels of the network. The background image will be regarded as a normal picture by people without shares. Owners who have reached the share of trapdoor numbers can recover a key target in an image. As the share increases, more key targets can be recovered. This paper is the first to propose secure secret sharing of images based on semantic targets. Through this method, it is possible to perform permission control on the target that needs to be divided and shared. Since the shared object is not the entire image, it can save storage space to a certain extent. Finally, through the analysis of the experimental results and comparison with other works, it can be concluded that the proposed scheme has a higher level of security and the amount of data that needs to be transmitted is small.

“…VC is a method in which cipher text can be decoded directly by the human visual system. One of the new cryptographic techniques is Visual Cryptography (VC) based on secret sharing developed by Naor and Shamir, which provides more data confidentiality while it requires less computation power only [3].…”

Visual cryptography technique is a secret sharing scheme used to encode secret visual information, in such a way that decoding process can be performed by a human visual system without any devices or complex computations to reveal the original secret. In this paper, we proposed a visual cryptography scheme for embedding gray secret image into two meaningful shares, and analyzed the relationship between the secret image and the meaningful shares, focusing our attention on improving the visual quality of the revealed secret by measuring the closeness or the differences in similarity between the secret image and the meaningful covers. Experimental results and case studies show that using covers that are less different from secret helps in obtaining a relatively good visual quality reconstructed secret image than using any covers.
