Efficient Data Security System Using Room Reservation Approach on Digital Images for Secret Sharing using Color Visual Cryptography

Aparna T. Deshmukh, Jyoti Raghatwan

Abstract: Reversible data hiding is the technique in which the cover image can reversibly be retrieved after the extraction of hidden data in it. This technique provides secrecy for data, and for its cover image. All the previous methods of reversible data hiding were vacating room for data hiding after encryption process, which leads tointroduction of some error rates at the time of data extraction and image restoration. Here we have described a novel method of reversible data hiding in which, Reserving room before encryption (RRBE) in images using visual cryptography, so that image extraction will be error free. Also here we are proposing an LSB replacement method for the data hiding, which will result in more space for embedding secret data.

Keywords: Reversible data hiding, RRBE, LSB replacement, visual cryptography
