TLDR
This paper proposes a blockchain-based data hiding method which interact with the blockchain record, where the external chain is utilized as the controller for the privacy data into carrier video, and removes the need for a trusted third party, enabling autonomous control of privacy data.Abstract:
The protection of secret data based on data hiding technique provides the basic security services for digital video through network transmission. However, the video with secret data is stored with centralized storage, which is vulnerable from external centralized attacks, such as the loss and tampering of the digital video. The protection of copyright and privacy data for digital video is still open issues. In this paper, we propose a blockchain-based data hiding method for data protection in digital video. To improve the integrity certification of secret data and the video, we combined the blockchain and data hiding techniques by adding the hash value to the block with a traceable hash value record; to improve the protection level of privacy data such as copyright related to digital video, we designed a DCT-based data hiding scheme which interact with the blockchain record, where the external chain is utilized as the controller for the privacy data into carrier video. Similar to Bitcoin, This system removes the need for a trusted third party, enabling autonomous control of privacy data.read more
