Significant Study of Data Encryption and Steganography

Abstract

Nowadays, the use of the internet is overgrowing throughout the world, which makes security a major concern for users.  Data is any information that is stored on a digital platform. Security is about the protection of data. Data security means digital protective measures which are applied to prevent data from hackers. Data encryption is one of the security measures which is used on data. If somehow anyone steals the data, he could not access the data if data is already encrypted. Data Encryption algorithms are developed in computer science to secure the data of senders and receivers. The security of communication is a crucial issue on the internet. Various encryption algorithms depend on data such as text, voice, picture, video, etc. In daily life, security has become a wide necessity. Information protection is perhaps the most important of all. The data is open to high potential risks in our framework. We adopt diverse methods for various security reasons. Now we are all relying on the security and storage cloud platform but also vulnerable to multiple threats. The data in the cloud is not well-secured because anyone who can enter our credentials can access it, and cloud providers do have fair access to us. This paper discusses various data encryption techniques and much more.
