Recursive Information Hiding in Visual Cryptography
نویسنده
چکیده
Visual Cryptography is a secret sharing scheme that uses the human visual system to perform computations. This paper presents a recursive hiding scheme for 3 out of 5 secret sharing. The idea used is to hide smaller secrets in the shares of a larger secret without an expansion in the size of the latter.

Hiding Medical Information of Patient through Image by Recursive Visual Cryptography
This paper introduces recursively hiding patient’s information using XOR based Recursive Visual Cryptography. The XOR based Visual Cryptography Scheme (VCS) encodes a secret image of data into several shares which are not understood by intruders individually. Here (2, 2) VCS is considered for paper. Its pixel expansion has more columns then original and same number of rows but the image quality...
متن کاملA Recursive Threshold Visual Cryptography Scheme
This paper presents a recursive hiding scheme for 2 out of 3 secret sharing. In recursive hiding of secrets, the user encodes additional information about smaller secrets in the shares of a larger secret without an expansion in the size of the latter, thereby increasing the efficiency of secret sharing. We present applications of our proposed protocol to images as well as text.
متن کاملMultiple Image Encryption using Random Circular Grids and Recursive Image Hiding
The visual secret sharing (VSS) scheme encrypts the secret information into various meaningless shares. These shares are distributed to the authorized participants and the secret information can be retrieved by any k out of n participants by stacking their respective shares on top of each other. This scheme uses HVS (Human Visual System) to decrypt the information, and thus no technical or fina...

This study combines the notion of both steganography [1] and visual cryptography [2]. Recently, a number of innovative algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency; because there will be always new kinds of threats in the field of information hiding. Actually Steganography and visual crypto...
