Hiding capacity of the data and its confidentiality plays a vital role in covert communication. A solution for this challenging part of the secure transmission is presented in this paper, wherein the security of transmission is ensured, by first encrypting the data that is to be transmitted by using the RSA algorithm, so the part of security and confidentiality of the message is covered and then Image Steganography is used. It is a technique where the transmitting data is hidden in an image. For hiding the information in an image there are many steganography techniques, in which LSB technique is chosen in this case. In this technique, the data is the text message which is converted into binary format by considering its ASCII values and then the bits of the information is hidden in the least significant bits of the R, G, B values of the pixels of the image.
