This paper presents a smart and secure data communication mechanism using image steganography technique. For these two secret messages are embedded into the single-color image. A hybrid combination of special domain and frequency domain techniques used for this purpose. In this proposed method two secret messages (i.e. in the form of image) are embedded by applying DWT on L channel of Kekre’s LUV color space model and LSB (Least Significant Bit) technique in Red, Green & Blue channel of RGB color space. By using this process, the extraction of the secret message becomes easy without access of the original cover image. The result & analysis of the proposed technique shows that it can resist various Steganalysis attacks.
