Enhancement of Efficiency in LSB Steganography Method Using Matrix Multiplication

The quick progression in the trading of data through internet made it simpler to trade information correct and quickest to the receiver. The security of information is one of the immense parts of information technology and communication. Steganography is a term utilized for data hiding and it is a craft of concealed written work. In steganography we hide information with a multimedia carrier i.e. image, text, audio, video files, etc. Thus, the observers can't locate the concealed data which we need to send to the recipient. Steganography principle objective is to give robustness, imperceptibility, and limit of hiding information because of which it contrasts from different methods, for example, watermarking and cryptography. In image steganography we shroud our secret information in image with the goal that the observer can't feel its reality. Image steganography procedures are starting late been valuable to send any secret message in the secured image carrier to foresee dangers and assaults, however, it doesn't give any kind of chance to programmers to discover the secret technique. Image steganography is efficient and better type than other types of steganography. The LSB method also faces the same challenge regarding the selection of which bits are used for hiding the data without effect the actual image pixels. This paper proposes a new technique used to hide information by image steganography using matrix multiplication in which we pick 6th , 7th , 8th bit of image pixel and add our message with it by applying some techniques and resultant will be added or placed at 6th , 7th , 8th bit of image. In this we made changes up to 3 bits, i.e. changes of seven in binary term, but we have to add +6 or -6 not the seven to form the stego image.
