Dynamic data is the big problem in big data and clouds. There are different resource available that create duplicate data. In this survey paper discuss the different data duplication avoiding methods. In the last decade there are different data duplication methods are proposed. In this present work discuss different method as well as compare those methods in the literature survey on the basis on survey problem proposed a modified hybrid AES-SHA 512 based Data De-duplication with Secure Encryption in Cloud. The main problem originate due to data duplication that is bandwidth consumption and space wastage due to same data. To avoid these problem researchers are focus on different data duplication techniques in last decade. In this proposed work use simple hash algorithm with advance encryption system for avidness of de-duplication in cloud. The proposed method output shows better result is compare to other previous method such as MD5, SHA – 1 as well as DSA in terms of security key generation time, encryption time and data duplicity find out time. Also the proposed method preserve same of the cloud server and bandwidth of communication channel.
