A Survey on Two Factor Security and Secured Data Retrieval from Cloud Storage System

In this project entitled objective is to download confidential file in a secure manner. Authentication is the first measure of defense against compromising confidentiality and integrity of data. Traditional download schemes are easy to implement, but they have been subjected to several attacks. As an alternative, tokens and biometric-based authentication systems were introduced. However, they have not improved to justify the investment. Thus, a change in downloading a file, several security methods was introduced. But it also suffered due to shoulder surfing and screen dump attacks. In this project, we introduce a framework of our Privacy Protection through “Secure confirmation of sensitive transaction�, which is immune to the common attacks suffered by other authentication schemes. A key is generated during registration phase of the project. When the registered user tries to download a file then a onetime password is generated which is matched with the key. The file is downloaded only when the key and the onetime password are matched otherwise downloading process is denied. Thus the file is downloaded in a secure manner.
