“…These schemes have been utilized in numerous applications such as biometric privacy, online payment systems, anti-phishing frameworks, and authentication based on signature, as summarized in [4]. Moreover, a very recent work [7] reviewed various visual cryptographic schemes based on different pieces of research related to this area, and cited the relevant literature. Furthermore, different VC schemes have been compared in terms of various performance criteria such as pixel expansion, visual quality and security.…”

Over the years, cryptography has been used to encrypt secret data. A new version of cryptography, entitled visual cryptography (VC), has been introduced. This approach is a simple and secure way to allow the secret sharing of images without any cryptographic computations or the use of encryption or decryption keys. Although various studies have been undertaken with regard to improving the VC technique, there has not yet been a study attempting to improve the VC technique for Arabic text although there are thousands of websites that provide services in Arabic serving countries in which Arabic is spoken as a first language. This paper, therefore, develops a tool that can encrypt/decrypt images of Arabic text using the VC approach. We experimentally evaluate the usability aspect. The results indicate the general suitability of the developed tool. This tool sheds light in designing practical tools for electronic voting, antiphishing, Captcha, watermarking, biometric privacy, online payment systems, and digital signature in the Arabic environment.

“…The VSS schemes based on XOR recovery solve the problems of the requirement of alignment in the decryption phase and complex computation. 18,19,20 In 2007, Wang et al presented a method for visual secret sharing using Boolean operations. 21 In their method, according to the input secret image 𝑆 and the number of shares which is 𝑛, 𝑛 + 1 random matrix is generated (𝐵 1 , ...., 𝐵 𝑛+1 ).…”

In this paper, a new scheme for lossless meaningful visual secret sharing by using XOR properties is presented. In this method, the input secret image is converted into several share images and these shares are distributed among individuals. In the proposed method, noise-like share images are generated using properties of XOR and genetic algorithm. In the next step by using other properties of XOR, shares become meaningful. In recovery phase the input secret image is fully recoverd by an efficient XOR operation. The proposed method is evaluated using PSNR, MSE, BCR criteria and presents good results on different images with different number of shares compared with other methods. The exprimental results show that the quality of generated share images is satisfable too.

“…The basic idea is to replace each pixel in an image with a block of pixels. The pixel information in the pixel block is filled with the superposition between pixels, and finally, an encrypted image cannot be recognized by the human eye [4][5][6][7][8][9][10][11][12][13]. For a (k, k)-threshold scheme, the information transmitting end encrypts the secret image into k share images and transmits them to the receiving end.…”

“…Since each secret pixel can be rendered by a block of pixels in a recovered image, ordinary visual cryptography has better visual quality. However, the recovered secret image is larger than the original secret image [5]. In 2002, Nakajima and Yamaguchi proposed extended visual cryptography for natural images [16].…”

Flip Extended Visual Cryptography for Gray-Scale and Color Cover Images

et al. 2020

View full text Add to dashboard Cite

Visual cryptography (VC) has found numerous applications in privacy protection, online transaction security, and voting security, etc. To counteract potential cheating attacks, Lin et al. proposed flip visual cryptography in 2010, where a second secret image can be revealed by stacking one share with a flipped version of another share. The second secret image can be designed as an additional verification mechanism. However, Lin’s scheme produces meaningless shares and is only applicable to binary secret images. It is interesting to explore whether it is possible to extend the flip VC to having cover images (i.e., extended VC) and these cover images are color images. This problem is challenging since too many restricting conditions need to be met. In this paper, we designed a flip VC for gray-scale and color cover images based on constraint error diffusion. We show that it is possible to meet all the constraints simultaneously. Compared with existing schemes, our scheme enjoys the following features: Color cover images, no computation needed for decoding, and no interference from cover image on the recovered secret image.
