DATA HIDING IN ENCRYPTED IMAGES AND VIDEOS


.pptx  DATA HIDING.pptx (Size: 48.45 KB / Downloads: 79)

ABSTRACT

ENCRYPTION OF DATAS IN INAGES HAVE MANY PROBLEMS.
SINCE THE ENTROPY OF ENCRYPTED IMAGE IS MAXIMAL,THE EMBEDDING STEP,CONSIDERED LIKE NOISE,IS NOT POSSIBLE BY USING STANDARD DATA HIDING ALGORITHM.
OUR IDEA IS TO APPLY THE DATA HIDING ALGORITHM ON ENCRYPTED IMAGE BY WISHING TO REMOVE THE EMBEDDED DATA BEFORE THE IMAGE DECRYPTION.
WE PROPOSE AN ANALYSIS OF THE LOCAL STANDARD VERSION DEVIATION OF THE MARKED ENCRYPTED IMAGES IN ORDER TO REMOVE THE EMBEDDED DATA DURING THE DECRYPTION STEP.

EXISTING SYSTEM

ENCRYPTION OF ORIGINAL UNCOMPRESSED IMAGE USING AN ENCRYPTED KEY TO PRODUCE AN ENCRYPTED IMAGE.
THE DATA HIDER COMPRESSES THE LEAST SIGNIFICANT BITS(LSB) OF ENCRYPTED IMAGE USING A DATA –HIDING KEY TO CREATE A SPARSE SPACE TO ACCOMMODATE THE ADDITIONAL DATA.
SINCE DATA EMBEDDING ONLY AFFECTS THE LSB,IMAGE RETRIED CAN BE SIMILAR TO ORIGINAL IMAGE.

PROPOSED SYSTEM

WE ARE SCOPING FOR A COMPREHENSIVE COMBINATION OF IMAGE ENCRYPTION AND DATA HIDING COMPACTIBLE WITH LOSSY COMPRESSION PROCESS.
WE ALSO SCOPE TO PERFORM TO PERFORM THIS ENCRYPTION SCHEME NOT ONLY IN IMMOVABLE PICTURES,BUT ALSO IN VIDEOS.
