Abstract: In the past decade cloud computing has been used extensively in industry, personal storage, military, government, etc. Even though storing and accessing data has become a lot easier due to significant development in cloud computing in the last two decades, and there are some issues with increasing dependency on cloud, the biggest issue among many is how secure is data and information in the cloud. So, considering security as priority this paper presents a study on file security using hybrid cryptographic methods. Two of the main constituents of cloud data are text file and multimedia files and here two methods are discussed one each for text file and multimedia file These security issues can be solved using both cryptography and steganography. It can still be improved by using multiple steganography and cryptography techniques.
Keywords: Cryptography, steganography, security, computing, hybrid.
