摘要：The art of information hiding has become an important issue in the recent years as security of informationhas become a big concern in this internet era. Cryptography and Steganography play major role forsecured data transfer. Steganography stands for concealed writing; it hides the message inside a covermedium. Cryptography conceals the content of a message by encryption. QR (Quick Response) Codes are2-dimensional bar codes that encode text strings. They are able to encode information in both vertical andhorizontal direction, thus able to encode more information. In this paper a novel approach is proposed forsecret communication by combining the concepts of Steganography and QR codes. The suggested methodincludes two phases: (i) Encrypting the message by a QR code encoder and thus creating a QR code (ii)Hiding the QR code inside a colour image. This hiding process embeds the quantised QR code so that itwill not make any visible distortion in the cover image and it introduces very minimum Bit Error Rate(BER). Experimental result shows that the proposed method has high imperceptibility, integrity andsecurity..
