Abstract- “Secure Backup” is a web application that provides a simple to use (Graphical User Interface) GUI, which facilitates users to store data of any format in a secured manner. This system is designed in a way that users can encrypt the selected files and upload them in to a local system, a database. Security has problems like multi tenancy, information loss and leakage, simple accessibility of cloud, identity management, internal threats etc. The proposed application provides security to the data in terms of authentication and confidentiality. This application verifies the authentication of the user by traditional mechanism called password verification, One Time Password generation and CAPTCHA verification. User need to be validated by providing details likeOne Time Password within 10 seconds, else the session will be expired. Other authentication mechanism like CAPTCHA that differentiates humans and machine inputs. The files that are being uploaded will be stored in the local system for backup. Whenever the user needs a backup the data is processed and can be downloaded by the user. The files uploaded can be encrypted using triple DES algorithm, a symmetric block cipher. On the basis of security requirements, a security key is added during the time of encryption and the same key given while decrypting the respective file. The prime conviction is to assure security to the data by storing the data in an encrypted format in to a database.
