Security of data can be achieved by implementing steganography techniques. All of the existing steganographic techniques use the digital multimedia files as a cover mediums to conceal secret data. Audio file use as a cover medium in steganography because of its larger size compare to other carrier's file such as text, image. So there are more possibilities to hide large amount of data inside digital audio file. Signals and digital audio files make suitable mediums for steganography because of its high level of redundancy and high data transmission rate. This is not easy to hide data in real time communication audio signals. In this paper we will survey the overall principles of hiding secret data in audio file using audio data hiding techniques, and deliver an overview of present techniques and functions and also discuss the advantages and disadvantages of different types of audio steganographic methods.

Several ocular and orbitaldisorders require surgical intervention that may result not only in ocular defects but also have a crippling effect on the psychology on those affected. 1 Maxillofacial prostheses which restore and replace stomatognathic and associated facial structures with artificial substitutes, aim to improve the patient's aesthetics, restore and maintain health of the remaining structures and consequently provide physical and mental well-being. 2 Enucleation of the eye is therefore normally followed by fabrication of an ocular prosthesis to improve esthetics. The primary purpose of an ocular prosthesis is to maintain the volume of eye socket and create an illusion of a healthy eye and surrounding tissues. The present article describes the prosthetic management of patient with ocular defect with a custom made ocular prosthesis.
