Abstract
As there is large advancements in internet technology, there has been huge text as well as multimedia data transfer over the internet. Due to this data security is a vital necessity. Various sensitive data is shared over the insecure channel, making it prone to hacking and external threats. Information hiding plays an important role in authentication. As Cryptography alone is not that secure, so we use Steganography along with cryptography to enhance security. For the first level of security we use CNN algorithm for encryption of the information and hash code which is generated by MD5 hashing algorithm for authentication. Then the cipher text and hash code are embedded in the image using LSB steganography algorithm for the second level of security. Then the image is fragmented into multiple parts for the third level of security, so that if a hacker retrieves the message he will only get partial text. After transmission the receiver receives the message, they reverse the process to obtain the information and they can also authenticate the message using hash code. This way triple security is achieved for safe transmission of data.
