Secure Data Transmission with Steganography

The importance of secure and private communication and file sharing has increased in an era of escalating data security concerns. Our research aims to address this need by developing a comprehensive Secure File Sharing Application that ensures the confidentiality and integrity of shared files. It provides user registration and login functionality, allowing users to create accounts with email and password authentication. Users can choose which files to share, and the application encrypts the files using powerful encryption algorithms like AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman) before sending them. Steganography techniques are used to securely embed encryption keys within innocent images, keeping them concealed from prying eyes. In order to take advantage of cloud storage's scalability and durability, encrypted files are kept in an AWS (Amazon Web Services) S3 (Simple Storage Service) bucket. Users can send the image containing the hidden decryption key to the intended recipient via email, ensuring secure transmission. The combination of Strong cryptography and steganography techniques enhances the security of the application, ensuring that only authorized recipients can access the shared content.
