chapter, a detail introduction of the fundamental concepts related the
presented thesis is discussed. In the latter half of the chapter, problem
description and research objectives are described.
With the rapid advancement of network technology,
multimedia information is transmitted over the Internet conveniently. Various
confidential data such a similarity map sand commercial identifications are transmitted
over the Internet. While using secret images, security issue should be taken in
to consideration because hackers may utilize weak link over communication
network to steal information that they want. To deal with the security problems
of secret images, various image secret sharing schemes have been developed.
Visual cryptography is a cryptographic technique
which allows visual information (e.g. printed text, hand written not sand
pictures) to be encrypted in such a way that the decryption can be performed by
the human visual system, without the a id of computers.
1.1.2 Cryptography for better Authentication
techniques provide a secure method of authentication for any kind of system or
provide a high level of security. Cryptography Scheme is an encryption method
that uses combinatorial techniques to encode secret written materials.
Today, most applications are only as secure as their underlying
system. Since the design and technology of middleware has improved steadily,
their detection is a dif?cult problem. As a result, it is nearly impossible to
be sure whether a computer that is connected to the internet can be considered
trustworthy and secure or not. The question is how to handle applications that
require a high level of security. For advance kind authentication different
cryptography techniques are used visual cryptography is one of them
The prime objective of this project is to ensure the
security of information (in this case image) transformation by creating image
Sharing images using visual
