A Copyright Protection Scheme of Visual Media in Big Data Environment

Abstract

Rapid development and application of big data technology is speeding up the dissemination and utilization of visible media big data. The intensive application of visual media brings about some security issues. The building of copyright protection mechanism of visual media big data under Internet environment can provide safety guarantee for content services of visual media in a digital library, and enhance integrated serviceability of digital resources in the digital library. Firstly, sparse features are extracted by exploiting the data sparsity and perception sparsity of visual media, and then a sparse perception computing model for visual media big data is built. Then the design idea of visual media copyright encryption, copyright authentication, copyright notice, and audit trail scheme are given from the point of view of sparse feature computation of visual media. Finally, a copyright protection application scheme of visual media big data under the network environment is developed. Its application in the digital library validates the effectiveness of this copyright protection mechanism of visual media. It can safeguard the confidentiality, integrity, availability, and auditing of visual media big data in the digital library, and enhance content serviceability of visual media in the digital library under big data environment.
