Analysis on Hybrid Approach for (K, N) Secret Sharing in Visual Cryptography

Visual cryptography (VC) is an emerging area used for data hiding, authentication, multimedia security and transmission of data. Parameters mainly focused in VC are pixel expansion, number of frames, type of images and number of undisclosed message images. Recent research shows many applications uses visual cryptography concept in authentication, secure transaction, secret sharing of information. But visual cryptography shows limited security for VC shares results in lack of security measure. In this paper work different VC (K, N) secret sharing techniques discussed and following analysis shows hybrid approach algorithms used in recent years that can be used for various applications in further implementation with high confidential secret sharing of data.
