In this paper, a new method for data hiding has been proposed. Determinant of the designed matrix has been used for the insertion and retrieval of the message. Matrix is designed from the four least significant bits of the selected pixel value. The pixel for insertion and retrieval of the message has been selected by using linear mathematical equation which is shared between sender and receiver. The four least significant bits of selected pixel value are adjusted according to the message bit and the determinant of the designed matrix. The experimental results show that there is very less deflection in the quality of the stego image which cannot be perceived by HVS (Human Visual System).
