Steganography&Cryptography for Regimented Data Hiding System: A Review

Nowadays, due to rapid development of communication techniques & its applications over the open communication channel, security-issues have the top priority. Communication of secret information is a critical factor in information technology that continues to create challenges with increasing levels of sophistication. However, in recent years, two techniques cryptography and steganography have been used widely in direction to trim down the security issues but different terrains pose separate challenges. This paper presents a comprehensive investigation on modern as well as traditional security methods with their inadequacies in direction to explain accessible security techniques in better way to new researchers and motivate them to design and implement a novel system that improve the level of security.
