OTP Camouflaging using LSB Steganography and Public Key Cryptography

Abstract

One Time Password (OTP) provides an additional layer of authentication to a web server, protecting against fraudulent attempts so that the information is protected between the user and the recipient. In the field of Steganography, various techniques are employed to conceal data in the media in such a manner that human perception cannot identify it. As the proposed algorithm is a combination of both Cryptography and Steganography it meets all the challenges very efficiently. Initially, the data is ciphered with a novel algorithm of asymmetric key cryptography and then the ciphered message is camouflaged in the cover media using the Least Significant Bit (LSB) steganography technique. Even if the intruder cracks the LSB algorithm used here, he will get the encrypted data since the source data is not present on the cover media. To obtain the original data, the ciphered data must be deciphered with the deciphering algorithm. With the additional security, it is impossible to crack the original data from the cover media
