introduction
This project is concerned with the application developed to embed information in a video signal so that data is protected from intruders.
This system makes the Files more secure by using the concepts Steganography and Cryptography.
The goal of cryptography is to make data unreadable by a third party.
Steganography, is the art of hiding messages inside other messages such that the very existence of the message is unknown to third party.
The cover data should not be significantly degraded by the embedded data ,and the embedded data should be as imperceptible as possible
Statements about the problem
Present day transactions are considered to be "un-trusted" in terms of security, i.e. they are relatively easy to be hacked.
And also we have to consider the transfer of large amount of data through the network will give errors while transferring.
Only single level of security is present in the existing systems.
Existing System
In the traditional the server was only a data base server that can only offer data. Therefore majority of the business logic had to be placed on the clients system .
So every client has to be trained as to how to use the application.
The data has to be transported over the network to the client, which requires a secured format of the transfer method.
Existing system offers only a single layer of security
Advantages of proposed system
High level security
Cost effective transfer
Efficiency
Flexibility
