In Data Security, Cryptography refers to encryption (at sender side) and decryption(at receiver side) of data and Steganography refers to the method of hiding a data in another form of data. Using only Cryptography is not as much secure as it was earlier as the hackers have become more skilled now-a-days. Combining Steganography with Cryptography is a secure method for transmission of data over the internet. In this paper, we have used Caesar Cipher cryptographic technique and combined it with “Image Steganography” to derive a secure method for data security.
