Nowadays, data has become increasingly heterogeneous and dynamic but also highly vulnerable to attacks, posing significant potential risks. To effectively secure multi-domain data, this paper presents a multi-domain security framework that leverages blockchain technology in combination withsteganography techniques, advanced encryption methods, decentralized access control, and smart contracts. The main objective is to ensure optimal data integrity, privacy, and authenticity. The proposed unified approach introduces a layered protection model that integrates concealment, authentication, access management, and auditability to defend against unauthorized access, data tampering, and malicious attacks.

摘要

Nowadays, data has become increasingly heterogeneous and dynamic but also highly vulnerable to attacks, posing significant potential risks. To effectively secure multi-domain data, this paper presents a multi-domain security framework that leverages blockchain technology in combination withsteganography techniques, advanced encryption methods, decentralized access control, and smart contracts. The main objective is to ensure optimal data integrity, privacy, and authenticity. The proposed unified approach introduces a layered protection model that integrates concealment, authentication, access management, and auditability to defend against unauthorized access, data tampering, and malicious attacks.
