Proxy driven data upload and Remote Integrity checking using MD5 Algorithm.

Computer Engineering

In today’s modern world internet has became an important source of information. Various methods or techniques are invented to extract useful information from the internet and one of the important field is Cloud Computing. It is the most reliable computing platform in these modern era .These clouds are used for storage purpose and various other purposes. Though it provides storage the data on the clouds needs to be safe and that’s why encryption is needed .The data from the cloud server should be checked whether it is being uploaded or it is downloaded. There are various threats like data stealing , data altering , etc. due to such type of threats “Proxy-Oriented Data Uploading and Remote Data Integrity Checking in Public Cloud" is taken under consideration. Cryptographic Proxy Oriented Data uploading secures the internal and external environment by avoiding the data from a invalid source. Though cloud services may be popular but due to high security the data which was uploaded from a illegal source or from a unauthorized user will be restricted. To counter this user can update their proxy or modify them and do the uploading task. The existing system cannot counter such type , so for this purpose the proposed system is to be taken under consideration .It does not provide access to unauthorized users . Proxy alteration makes it easier for the attackers to steal the data or to inject malwares into the cloud environment . The integrity of data also plays important role in data security . The proposed system checks the integrity of the data without actually downloading the actual data . Unlike other systems, data is to be downloaded and checked the integrity, this system does it remotely.
