Secure Auditing and Deduplicating in Cloud Computing using MD5 Algorithm

Abstract

This paper depicts about bringing a change in algorithm for the IEE paper “Secure auditing and deduplicating data in cloud computing”. This paper intends to reduce duplicated data. It uses MD5 algorithm for generating hash function during transaction to cloud. The MD5 algorithm splits the input data into 512kbs and then transmits, thus making the data transition simple and unbreachable. Even if the third party tries to access the data it would get only the part of the data since MD5 transmits data only with the size of 512kbs. The data which is been sent to the cloud is encrypted and then sent, thus making the data secure. Similarly during accessing those data the encrypted data is been decrypted and then accessed. These data which are been stored in the cloud can be accessed from anywhere around the world with the help of ONEDRIVE app. This paper uses ONEDRIVE by Microsoft as its cloud source. ONEDRIVE is available for both Ios and Android devices. By using this algorithm the data are saved and protected much better than the prior method. This algorithm ensures that the data are not been duplicated and it also provides maximum security. The working of this paper is tested and result is obtained successfully.

Keywords: Cloud storage, data de-duplicating, secure auditing, and MD5 algorithm.
