Security During Transmission Of Data Using Web Steganography

The enormous improvements in communications and related technologies, such as the Internet of Things (IoT) and its web-based and mobile applications, have changed our way of life. We are also noticing a trend in which internet-connected electronic devices are using technology more frequently and providing customers with services of a higher standard. However, there are several complications and issues that arise when sending and receiving information via the internet. The security, privacy, and preservation of sent information are the most critical of them all. The security of information has grown to be a significant problem with the expansion of data transfer across computer networks. There are numerous ways to safeguard data and prevent unwanted users from accessing it. Steganography and cryptography are two different data hiding and protection techniques. Steganography conceals communications within some other digital media. On the other side, cryptography obscures the message's content and makes it challenging for readers to decipher. To safeguard data, steganography can be combined with cryptographic methods. Combining steganography and cryptography for hidden data transmission is the best suggested method for protecting data transferred over the internet. A data carrier that is an image can be used for the transmission. With regard to capacity, security, and robustness for secure data transmission over an open channel, this combinational methodology will be sufficient. The purpose of this paper is to explain the steganographic security measures used to protect data while it is being transmitted across a network.
