The paper presents a new approach in Image steganography. Information security is the important research field. Steganography process hides message into cover file and forms a stego file. In image steganography there is a need of method which will increase the security, reduce the distortion in the stego file and recovers the data without any loss. In the era of multimedia and internet there is need of reducing time for transmission. The proposed approach is combination of compression, data hiding technique and encryption. To make the transmission and storage of digital data faster, lossy compression is used. On the compressed image data hiding is done. The stego image is encrypted using AES to ensure user authentication. If the receiver has encryption key and data hiding key then only he can obtain the secret message. Nodes are selected randomly in data hiding stage. On the randomly selected nodes lossless LSB steganography is used.
