As we enter the age of universal electronic connectivity, electronic eavesdropping and electronic fraud threaten the prosperity of corporations and individuals. Thus, the role of digital security has become increasingly important. The security requirements within an organization have undergone major changes in the last few decades. Before the widespread use of data processing equipment, data and information valuable to an organization were made invulnerable primarily by physical and administrative means. With the advent of computer networks and the internet however, the design of automated tools which ensure security and privacy of information transferred across networks was inevitable. Though there are several security techniques in use, two of the most prominent ones are steganography and cryptography. In this paper , we discuss these two techniques and how their combination can result in an efficient and secure data transfer software. |
