A meta-analysis of Video Data Security

Data Security is important in all field of data communication as it is very important so that any unauthorized access of data can be prevented. There are several ways to secure the data in which cryptography and steganography is the main. Data security is also depends on the data type. As there is not a single universal technique which can secure all the types of data. There is the need to change the proliferation and implementation so that it can be applied to different type of possibilities. In this paper we have discussed about video cryptography and steganography so that we will able to secure the video data.
