High-Capacity Reversible Data Hiding Based on Two-Layer Embedding Scheme for Encrypted Image Using Blockchain

In today’s digital age, ensuring the secure transmission of confidential data through various means communication is crucial. Protecting from malicious attacks during poses a significant challenge. To achieve this, reversible hiding (RDH) and encryption methods are often used in combination to safeguard intruders. However, existing hybrid techniques facing challenges related low embedding capacity. address these challenges, proposed research presents solution that utilizes block-wise two-layer scheme enhance capacity cover image. Additionally, this technique incorporates blockchain-enabled RDH method ensure traceability integrity by storing alongside hash value stego The work divided into three phases. First, image encrypted. Second, embedded encrypted using scheme. Finally, along with deployed blockchain technology. reduces associated while increasing images compared traditional methods.
