| In this present study a new method for insertion of message in an image is proposed. We have used last two bits of pixel for insertion and retrieval of message. This method is an improvement over earlier methods like Least Significant Bit (LSB) method [2], 6th and 7th bit method [5] and 6th, 7th and 8th bit method [6]. Our method provides us optimal solution in case of chances of message insertion at a pixel location such that the change at a pixel value does not exceed range from +1 to -1 which is negligible to human eye. |
