Abstract:
Secure File Upload is a web utility for the admin to store data/text files securely on a web server, The data to be uploaded is encrypted first at the admin side and stored in the database in an online mode .It efficiently makes use of HTML 5 local storage for caching the data and retain it after the admin has logged-off, When the admin logs in again he can see the files which he uploaded and encrypted at the server side , which he can choose to upload on the web server’s database and thus can remotely backup the file on a remote machine. The User after Logging can search the uploaded files to select and send request to admin. The advantage is that the file is encrypted. If the user wishes to download the file he can do so by clicking at the download button should enter the key given by admin to be matched, in order to segregate the unauthorized users. In which the file is downloaded and to be stored thus can be decrypted by the user and can be viewed by him.


EXISTING SYSTEM

The weaknesses of all encryption systems is that the form of the output data (the text), if intercepted, alerts the intruder to the fact that the information being transmitted may have some importance and that it is therefore worth attacking and attempting to decrypt it. This aspect of cipher text transmission can be used to propagate disinformation, achieved by encrypting information that is specifically designed to be intercepted and decrypted. In this case, we assume that the intercept will be attacked, decrypted and the information retrieved. There is no security when transmitting the data from one end to another.

PROPOSED SYSTEM

Encryption is the most effective way to achieve data security. The process of Encryption hides the contents of a message in a way that the original information is recovered only through a decryption process The purpose of Encryption is to prevent unauthorized parties from viewing or modifying the data Encryption occurs when the data is passed through some substitute technique, shifting technique, table references or mathematical operations. All those processes generate a different form of that data. The unencrypted data is referred to as the plaintext and the encrypted data as the ciphertext, which is representation of the original data in a different form. A symmetric Encryption key is used for this application, which means the same key is shared for both Encryption and decryption. The encrypted file can only be opened and viewed after it has been decrypted to its original file using the symmetric encryption key.
