Steganography is the art of hiding data, in such a way that it is undetectable under traffic-pattern analysis and the data hidden is only known to the receiver and the sender. In this paper new method of text steganography over the silence interval of audio in a video file, is presented. In the proposed method first the audio signal is extracted from the video. After doing audio enhancement, the data on the audio signal is steganographed using new technique and then audio signal is rewritten in video file again. http://www.learnrnd.com/All_latest_research_findings.php To enhance the security level we apply chaotic maps on arbitrary text. Furthermore, the algorithm in this paper, gives a technique which states that undetectable stegotext and cover-text has same probability distribution and no statistical test can detect the presence of the hidden message. http://www.learnrnd.com/detail.php?id=Biohack_Eyes_through_Chlorin_e6_eye_drop_:Stanford_University_Research Moreover, hidden message does not affect the transmission rate of video file at all.

The paper presents the method of transferring PCM (Pulse-Code Modulation) based audio messages through SMS (Short Message Service) over GSM (Global System for Mobile Communications) network. As SMS is text based service, and could not send voice. Our method enables voice transferring through SMS, by converting PCM audio into characters. Than Huffman coding compression technique is applied in order to reduce numbers of characters which will latterly set as payload text of SMS. Testing the said method we develop an application using J2me platform

Paper presents the way of transferring stereo images using SMS over GSM network. Generally, Stereo image is composed of two stereoscopic images in such way that gives three dimensional affect when viewed. GSM have two short messaging services, which can transfer images and sounds etc. Such services are known as; MMS (Multimedia Messaging Service) and EMS (Extended Messaging Service). EMS can send Predefined sounds, animation and images but have limitation that it does not support widely. MMS can send much higher contents than EMS but need 3G and other network capability in order to send large size data up to 1000 bytes. Other limitations are Portability, content adaption etc. Our major aim in this paper is to provide an alternative way of sending stereo images over SMS which is widely supported than EMS. We develop an application using J2ME Platform.
