“…When it is mentioned that a watermark approach is robust, it means that even after the watermarked protected image received various attacks, the watermark will still be able to be taken from the image [8]. Alternatively, the extraction activity should be influenced by the attacks.…”

“…Even though, in terms of the usage the LSB sounds very simple, the detection process of the watermarks is very difficult [7]. Although this approach is not easily detectable and there is not any distinguished variations between the original image and the watermarked image, this approach is not strong enough to protect the power of the images that are watermarked, meaning that in the spatial domain, where there is a chance of the capacity to be large, still the watermark could be easily detected by intruders.…”

the main aim of this paper is to introduce a novel approach to preserve digital images' copyrights. Hence as ISB scheme was selected in relation to the approach in an attempt conquer the issues of robustness and imperceptibility in watermarked imagery. According to the literature review, embedding the aimed secret bits (Watermark) is a problematic issue inside a host image (normal 8-bit, grey-scale) in a sense to make it undetectable by the HVS (Human Visual System) in addition to the matter that it is predicted to receive any attacks. The suggested method here represents an improved scheme for the embedding of ISB which maintains the robustness and cultivates the rate of security by employing repeated bits in various bit planes over an irregular order and it develops the LSB technique specifically in circumstances where robustness and imperceptibility are main points of assessment.Digital image watermarking; Intermediate Significant Bit; robustness in watermarking;security;

“…The general steps involved in this paper are described as follows. The first step has to embed the watermarking in the test inputs [9,10], then these images undergone half toning, that is the input images are converted into binary image. These binary images are encrypted into number of shares as per the prescribed scheme.…”

Security has become an indivisible question as Information Technology is ruling the world now. Cryptography is the technique to prove the inconceivable security for the secret data. Visual Cryptography is appropriate for any images, in which k out of n shares are enough to decrypt the clandestine information. It’s a method of isolating the secret among a group of contributors and each contributor get a share of the secret. Here sufficient number of shares is combined to expose the secret. Main applications of Visual Cryptography are Bank customer identification, Biometric security and so on. This paper provides such methods to maintain the privacy of an individual’s medical image and also embrace watermarking in the medical images, which provides copy right to the medical images of the concerned hospitals. Three Visual cryptography schemes are projected for medical image. Steps related to dividing the secret as shares are needed to be very hard to attack. These schemes mainly focused on decryption method, this act as an imperative utensil for getting efficient results.

“…To implement the act of recognition in machines we need to show an algorithm of millions of images before it makes a pattern by generalizing the input and start making predictions for images it has never seen before [36]. The aim is to evolve a more robust and imperceptible watermarking scheme that can cater to the needs of content protection [37].…”

In this paper we propose an algorithmic approach for Convolutional Neural Network (CNN) for digital watermarking which outperforms the existing frequency domain techniques in all aspects including security along with the criteria in the neural networks such as conditions embedded, and types of watermarking attack. This research addresses digital watermarking in deep neural networks and with comprehensive experiments through computational modeling and algorithm design, we examine the performance of the built system to demonstrate the potential of watermarking neural networks. The inability of intruder towards the retrieval of data without the knowledge of architecture and keys is also discussed and results of the proposed method are compared with the state of the art methods at different noises and attacks.
