摘要：More and more clients would like to store their data into cloud servers along with the rapiddevelopment of cloud computing. New accessing and traffic problems have to be resolved in order to help more clientsprocess their data in cloud network. All the cloud have certain space maintenance problems, so that a newmechanism is required in proposed system, which provides Quality of Service based data services over cloudenvironment. The main objective of the proposed system is to reduce the network traffic by means of single round tripinformation exchange and the trapdoor compression method as well as the intention is to reducing the dataretrieval time and improve the searching accuracy with proper speed. In this proposed system two new algorithms areintroduced to resolve the issues found in network environment, called the Trapdoor Mapping Table (TMT) Scheme andRanked Serial Binary Search (RSBS) Algorithm, which are used to improve the search time by increasing the speed. Toimprove the security overcloud environment several cryptographic approaches are used. When a cloud user uploadsfile, the file index is generated automatically and file is encrypted by using Advance Encryption Standard (AES)algorithm with automatically generated key. After that by Visual Cryptography Scheme (VCS), the key is convertedinto image and then generated as key image and source Images respectively. The encrypted file and the file indexes arestored in storage node, key and source image are stored in cloud server and key image is passed to file owner.Whenever file owner or file users want to download or access files, they perform search and put key image as an input.If valid, it matches the key with the source image and later it is downloaded.
