Abstract

Images are becoming an inevitable part of knowledge in the modern day society. As data is growing at a rapid rate, costs involved in storing and maintaining data is also raising rapidly. The best alternate solution to reduce the storage cost is outsourcing all the data to the cloud. To ensure confidentiality and integrity of the data, a security technique has to be provided to the data even before it is stored on the cloud using cryptography. An attempt is made to explore the possibility of usage of visual cryptography for providing robust security to the secret image. Visual cryptography proves to be more efficient than other cryptography techniques because it is simple and does not require any key management technique.
