A Novel Encrypted Data Hiding and Image Encryption for Authentication Based Communication Framework

For many real-time applications, including law enforcement, military communications, and medical data sharing, secure data sharing is essential. However, transmitting sensitive data presents a serious security risk because it can be intercepted or leaked. Here, we present a novel solution that combines cryptography and steganography approaches to overcome this difficulty. By encrypting information with AES encryption, concealing it inside a picture with Modified Least Significant Bit and picture encryption with Elliptic Curve Cryptography (ECC), the suggested solution seeks to improve data transmission security. AES encryption, encryption method renowned for its dependability and effectiveness, is used at the first layer of security. This guarantees that the plaintext communication, safeguarded by a powerful encryption key, stays private. But go one step further and use a modified Least Significant Bit technique to incorporate the AES-encrypted text within a cover image. ECC encryption uses elliptic curves' mathematical characteristics to produce safe digital signatures for the image that are verifiable and tamper-evident. The suggested method guarantees end-to-end security for confidential text messages by combining these two methods. The security of the message security is verified by the use of AES, and its secretion within an image is arrived through the changes of LSB embedding.
