Securing data is a challenging issue in today's era. Most of the data travel over the internet and it becomes difficult to make data secure. So Cryptography was introduced for making data secure. But alone cryptography cannot provide a better security approach because the scrambled message is still available to the eavesdropper. There arises a need of data hiding. So here the authors are using a combination of steganography and cryptography for improving the security.
