Hybrid Data Protection Method CombiningHomomorphic Encryption and Steganography

This hybrid method enhances data security by integrating homomorphic encryption (HE) and steganography. Homomorphic encryption enables computations on encrypted data without decryption, ensuring confidentiality during processing. Steganography conceals the very existence of this encrypted data by embedding it within digital media such as images or audio files, providing communication stealth. Together, these techniques protect both the content and the presence of sensitive information, making the approach suitable for secure cloud computing, covert data transmission, and privacy-preserving applications.
