Voice Signal Encryption Scheme Using Transformation and Embedding Techniques for Enhanced Security
P. L. Chithra, R. Aparna · 2018
Voice is the most common mode of human interaction. Speech signal plays a vital role in communication and data transmission. It will be very convenient to transfer data in the form of speech to exchange data in easy and faster way. Voice communication also adopted in various fields for easy data exchange. Data flow enormously in open network. Hence it is considered as most vulnerable part where intruders attempt to access secret data that are transmitted across the network. It is essential to devise competent method to enhance data security during voice transmission. In this paper, an efficient technique is proposed for enhanced security in voice signal encryption scheme. The inclusion of transformation and embedding techniques further makes the system very secure for speech signals over open network paths.
