Natural image based Visual Cryptography is an efficient technique used to secure sensitive images. Here images are hidden inside shares which appear as noise-like images. Now a days utmost concern is given to the privacy of images which includes fingerprint, signature and other secret information. This scheme suffers a high transmission risk since the secret images are hidden inside shares. In this paper, the generated share is firstly hidden in a printed media using QR technology and secondly in a cover media with the help of steganographic techniques. It enhances the security and reduces the risk of eavesdropping in the transmission phase. Experimental results show that steganography performs better. The average PSNR values of Steganography and QR technology are 26.81 dB and 22.45 dB respectively.
