Volume : III, Issue : V, June - 2013 SECURE IMAGE DA T ABY THREE ST AGES OF ENCRYPTION USING BLOCK BASED TRANSFORMA TION GAYATHRI D. AND SUMETRAMENARIA DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : Information security is an incr easingly important problem in the present era of
advanced technology , because of which encryption is becoming very important to ensure
security . Popular application of multimedia technology and incr easing transmission
ability of network gradually leads us to acquire information directly and clearly thr ough
Images. The digital images, which ar e transmitted over the internet, must be protected
fr om unauthorized access during storage and transmission for communication,
copyright protection and authentication purposes. This can be accomplished using
image encryption which is an intelligent hiding of information. Encryption is the process
of converting an image fr om readable form to unreadable form. In this paper , I have
encrypted an image at thr ee stages for incr easing the entropy and to decrease the
correlation between the pixels using block based transformation.Experimental results
demonstrate that the algorithm is sensitive to initial conditions to resist the brute-force
attack. Keywords : Article : Cite This Article : GAYATHRI D. AND SUMETRAMENARIA, (2013). SECURE IMAGE DA T ABY THREE ST AGES OF ENCRYPTION USING BLOCK BASED TRANSFORMA TION.
