The blockchain and decentralized manipulation of confidential information: uses in medical healthcare and assisted reproduction

This article addresses monetary remedies in employment team move and misuse of confidential information cases. It argues that, after the Supreme Court's decision in One Step (Support) Ltd v Morris-Garner, negotiating (previously Wrotham Park) damages offer a useful additional compensatory tool in misuse of confidential information cases. They can help overcome some of the difficulties with ordinary contractual damages, equitable remedies for breach of fiduciary duty and confidence and limitations in injunctive relief. While One Step is restrictive overall, there is a real role for negotiating damages in employment cases where misuse of confidential information is the sole or predominant breach of contract. The well-established Faccenda approach is suggested for identifying the requisite confidential information.

Confidential Information

Steganography is the special art of hidding important and confidential information in appropriate multimedia carrier. It also restrict the detection of hidden messages. In this paper we proposes steganographic method based on dct and entropy thresholding technique. The steganographic algorithm uses random function in order to select block of the image where the elements of the binary sequence of a secret message will be inserted. Insertion takes place at the lower frequency AC coefficients of the block. Before we insert the secret message. Image under goes dc transformations after insertion of the secret message we apply inverse dc transformations. Secret message will only be inserted into a particular block if entropy value of that particular block is greater then threshold value of the entropy and if block is selected by the random function. In Experimental work we calculated the peak signal to noise ratio(PSNR), Absolute difference , Relative entropy. Proposed algorithm give high value of PSNR and low value of Absolute difference which clearly indicate level of distortion in image due to insertion of secret message is reduced. Also value of relative entropy is close to zero which clearly indicate proposed algorithm is sufficiently secure.
