Digital Assets and Blockchain-Based Multimedia Data Management
Abstract: With the emergence of blockchain technology, decentralized and trustworthy platforms for data storage and propagation transactions become available, which can improve the security of the digital assets, i.e., data with their right to use (e.g., authority, ownership, fingerprinting, etc.). However, the security mechanism of blockchain suffers more vulnerabilities when it is being attacked and when managing multimedia data. It remains challenging to secure multimedia data and protect data integrity. Meanwhile, multimedia data could contain critical personal information. Research in privacy-preserving multimedia data management needs to be further studied to enable using and analyzing multimedia digital assets in the decentralized system without personal information leakage. This is an important feature to enable applications, such as surveillance and e-health. While blockchain sheds light on the future of multimedia data management, further research on secure and privacy-preserving management for digital assets and multimedia data is needed.
