Comparative Study of Various Visual Cryptography Techniques to Analyze the Quality of Reconstruction
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Visual cryptography is one among the cryptographic techniques available, where the secret information is encrypted by giving a key. The secret image will be encrypted into n number of shares. By stacking the shares, the original secret image is decrypted. Here, decryption uses human eyes to recover the secret image without any complex decryption algorithm. Visual cryptography is unique way to protect secrets. This paper compares various algorithms used in visual cryptography in terms of quality, security and size of the recovered image.
