Abstract: In current digital era, people are using e-devices such as ipods, iphones and cell phones for capturing the static and dynamic images. However, these images have a compromised size and quality due to fixed memory dimension. But, in the multi-media messaging service (MMS) of cell phones and iphones, they may participate as a cover medium, strengthening the steganography communication. The different methods of steganography are mostly applied on image files to embed the data. In all these cases, the principle of replacing the entire or some parts of the chosen pixel may not be able to utilise all the available memory area of an image for the purpose of the secret data. This paper presents a new high capacity steganographic technique to hide information. Three different techniques out of which two are to embed the plain text and one is for all type of data to embed in image. Based on these methods, we have constructed secured MMS creator and short message service creator viewer in Microsoft platform for providing data embedding in new e-devices.

Keywords: stego keys; user classified multi-valued code; reduced ASCII code; direct replacement; steganography; information hiding; MMS; multimedia messaging service; cell phones; mobile phones; iphones; image files; plain text; SMS; short message service; secret data.
