Secured Image communicator
Abstract:
Internet based communications are evolving at a tremendous
rate. Encryption of data has become an important way to protect
data resources especially on the Internet, intranets and extranets.
Encryption involves applying special mathematical algorithms and
keys to transform digital data into cipher code before they are
transmitted and decryption involves the application of
mathematical algorithms and keys to get back the original data
from cipher code. The goal of security management is to provide
authentication of users, and integrity, accuracy and safety of data
resources. Moreover, an image-based data requires more effort
during encryption and decryption.
In most of the defense and other research organizations, they need to
send and receive the import images related to weapon designs, maps,
satellite pictures etc. If those images are sending normally hackers can
tap the images and import information is leaked out.
In order to overcome this difficult, the image to be processed is first
encrypted and then it is decrypted so that no intermediate users can
read the images unauthorized. For this standard encryption, decryption
algorithms are used such as RSA, AES, DSA etc.
Some of the functions of the proposed system:
1. User Management
This is the option of admin. This system is provided with two types of
users. One Admin and second is operator. Admin do user
management.
2. Encrypting Images
Images are encrypted in this operation.
3. Decrypting Images
Any image can be decrypted to its original format,
4. Sending Images
An Encrypted image can be forward to a user.
5. Receiving Images
It is possible receive the sent images through this.
6. Change Password
It allows an operator to change his/her password whenever it is
needed.
