“…Around all types of files could be included in the mainframe image Steganography, but images were proven to be the most complete aspect of the embedding due to their high level of joblessness. When we analyze, discuss, and extend steganography techniques, three considerations [13][14][15][16] must be considered: ➢ Capability: switch to the sum of data that can interleave to the swathe reflection, which was called payload for a moment [17]. ➢ Resilience: conflicts with various compressed image processing.…”

Visual encryption technology becomes the latest research area in which a lot of scopes persist. Presently such a particular cryptosystem procedure is now used by numerous other countries around the world for the private transmission of formal records, financial documents, content visuals, digital voting, and so on. Visualization Cryptographic algorithms one of the protected methods of transferring pictures online. The main benefit of image encryption has been that it disguises peripheral vision with encrypt data secret data with no computation usually needed. In this work a hybrid visual cryptography method using a sigmoid function (HVMSF) for enhancing the security in gray images. HVMSF strategy utilizes a chaos framework to scramble pixel values as well as blocks while using the Modified Arnold Cat Map method (MACM) as well as the Henon Map method (HMM). The methodology includes a confusion procedure wherein the location of each image pixel is shuffled by utilizing MACM. The shuffling of image pixel leads to the creation of a subset pixel which will be protected for transmitting. This proposed HVMSF mainly tries to overcome the limitation of the previous approaches by applying sigmoid function in image feature space for contrast enhancement throughout the consequent source images. The experimental outcomes precisely show that the suggested strategy can further give additional effectiveness to ensure the protection of transmitting information out over previous techniques.

Visual cryptography is an encryption technique that decomposes secret images into multiple shares. These shares are digitally or physically overlapped to recover the original image, negating the need for complex mathematical operations or additional hardware. There have been many variations of visual cryptography proposed over the years, each addressing different problems or to fulfill different security requirements. Existing review papers on the area only cover certain types of visual cryptography or lack comparisons between the various schemes. To address this gap, this paper provides broad overview of the area to aid new researchers in identifying research problems or to select suitable visual cryptography methods for their desired applications. For more veteran researchers in the area, our paper provides the most up-to-date coverage of the state-of-the-art. We first provide an introduction to the various categories of visual cryptography techniques, including a discussion on recently proposed schemes. These schemes are then compared in terms of their features, performance metrics, advantages and disadvantages. Compared to prior work, we extend the number of comparison metrics to include signal-to-noise ratio and the type of shares. Over 40 visual cryptography schemes that have been proposed in the past two decades were analyzed and compared. Our findings indicate that existing problems such as pixel expansion, poor quality of recovered image quality, computational and memory complexities still exist, and a optimizing the trade-off between these requirements still requires further investigation. We conclude the paper with a discussion of these open problems and future research directions.

The development of a secure online voting system using visual cryptography is highly essential for present voting systems. Based on the current requirements and design aspects of an existing online voting system, emerging technologies are required in online voting schemes, and these are examined in this work. The emerging cryptographic techniques which are suitable for secure online voting systems are analyzed. Techniques like password hashed-based schemes, visual cryptography, and threshold decryption cryptosystem are highlighted for secure online voting systems. Visual cryptography (VC) is a technique where visual information can be encrypted on the user side, with the information decrypted on the admin side, which can be helpful in allowing participation in voting systems securely and ensuring fast vote counting and monitoring of the voting process to achieve high accuracy while being scam-free. The proposed secure online voting system using visual cryptography is efficiently developed using Python and achieves better performance on minimum software and hardware configuration systems.
