“…Share1 Share 2 Staking of Share1 & Share2 While creating and combining the shares some problems such as pixel expansion, alignment problem, flipping Issues, and share distortion, cheating of shares may arise [5], [6]. In pixel expansion numbers of pixel in share are increased, due to that size of share increases and alignment problems may occurs.…”

“…Mahmoud E. Hodeish et.al proposed an optimized half tone visual cryptography using error diffusion. They works on binary and gray scale image and improves the pixel expansion, elements the code book requirement but they only works on binary half tone images [6]. Mahmoud E. Hodeish et.al proposed a new efficient TKHC-based image sharing scheme over unsecured channel they proposed the method of RGB and gray scale images encrypted and decrypted by means of TKHC and providing strong security to transmit all the generated shares via one public channel [9].…”

A secure and verifiable color visual cryptography has becoming an important field of study in recent development of visual cryptography. In recent era there is a need of security and verifiability of shares.This research paper introduce the new secure and verifiable color secrete sharing scheme which identifies and analyses cheating while presenting the share. Integrity and reliability of share is identified before superimposition of share to revel the original secrete image. Secrete and verification image of size n x n are used for creating two shares then created shares are embedded into two cover images using LSB (Least Significant Bit) based stenography to create the meaningful and stenographic shares. Color channel decomposition and Jarvis half toning method is applied on each color channel of RGB secrete and verification image for creation of shares. Method proposed eliminates the problem such as explicit requirement of codebook design, pixel expansion, and poor visual quality of reconstructed images. Structural Similarity(SS) and Mean Square Error(MSE) measures of original verification image with revealed verification image verifies the soundness and originality of the secrete. The method also compares the result with previously proposed method; experimental results and statistical analysis are used to prove the efficiency of the method proposed.

In the present study, an algorithm for big data encryption has been designed which is concerned with encrypting data in a short time and in a safe manner and difficult to be penetrated by attackers and hackers according to the mechanism used for encryption in this study.The proposed algorithm is a development of an earlier NSCT algorithm. This development is based on adding a key expansion mechanism to generate keys by F-function, and also the number of cycles have been reduced to get less time. The proposed algorithm has been implemented in three stages; the first stage is implemented by FELICS simulation to find out the efficiency of the algorithm. In thesecond stage the proposed algorithm is implemented on the Java language to encrypt the text and to find out the execution time for the encryption. In the last step, the proposed algorithm is implemented on the MATLAB language to encrypt images and to knowthe performance of the algorithm in terms of countering attacks by hackers.After performing these steps and obtaining the results presented in this study, we can say that the proposed algorithm is capable of dealing with big data and that it can be considered safe and free from risks

<span>If data security issues in a big data environment are considered, then the distribution of keys, their management, and the ability to transfer them between server users in a public channel will be one of the most critical issues that must consider on. In which the importance of keys management may outweigh the importance of the encryption algorithm strength. Therefore, this paper raised a new proposed scheme called (AKMS) that works through two levels of security. First, to concerns how the user communicates with the server with preventing any attempt to penetrate senders/receivers. Second, to make the data sent vague by encrypting it, and unreadable by others except for the concerned receiver, thus the server function be limited only as a passageway for communication between the sender and receiver. In the presented work some concepts discussed related to analysis and evaluation as keys security, data security, public channel transmission, and security isolation inquiry which demonstrated the rich value that AKMS scheme carried. As well, AKMS scheme achieved very satisfactory results about computation cost, communication cost, storage overhead which proved that AKMS scheme is appropriate, secure, and practical to use and protect the user's private data in big data environments.</span>
