摘要：The security of information is the essential part of organization and security mechanisms need to be implemented. The cryptographic and steganographic methods is one of the techniques of security in which cryptography encrypts the message and steganography hides the information in any digital media file such as sound, image file, etc. In this, the Steganographic method is used based on audio steganography which is concerned with embedding secret data in an audio file. Along with this, the hashing method has been used for information confidentiality and image file concept has also been used for information hiding. The basic idea behind this is that the information should not be centralized but in multiparts storage so that the intruder cannot detect it. Firstly the information is processed under hash algorithm, then cryptographic method has been implemented to be more secure and then, the some part of the information will be hiding in multipart audio and last part in image file. This step provide more security because for data decryption, the all files will be needed else information will not be able to detected. For hiding in media file, the LSB (Least Significant Bit) technique is implemented which replaces the LSB of audio with binary of information. The least significant-bit (LSB) based technique are very popular for steganography in spatial domain .In the networking scenario, the information is shared among the users and this information should be confidential and authenticated to the receiver. The information should be kept in secure medium for protect from the intruders. So the data hiding technique should be used for keep the information available to the users.
