slugAn Improved Mechanism of Secret Data Hiding in an Image and Enhanced Security by Minimized Detection
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 2
Abstract
Steganography is the art of hiding information and an effort to conceal the existence of the embedded information .In recent years many stegnography methods have been challenge by stegnalysis. Steganalysis algorithm which detects the stegomesage by the static analysis of pixel values [1] . In the proposed method , the secret message is enoded by using vigenere encryption method which guarantees the protection of hidden message. Then hiding the secret text in an image by using first component alteration technique .In this technique, 8 bits of blue components are replaced with secret data bits , then that image can be hidden in cover image in non sequential pixel by using variable hope value power of 2 [2,4,8,16].the Proposed method aim not only to provide improved security and capacity problems of simple LSB method but also the increased visual quality of stegoimage.
