In the digital era, it’s more difficult than ever before for photographers to keep track of where their work is being reproduced. Blockchain technology can be used to register and protect against copyright infringement. A public decentralized ledger like the Blockchain is ideal for cataloging and storing original works of art, photographs and images, away from any central authority.
How Blockchain helps, first, for identity authentication. Through the database that based on Blockchain technology, the real identity of appliers can be verified in a fast way, then to protect the legal identity for users.
Second, for authorization and tracking, the whole processing would be recorded on Blockchain at the same time. This is called traceability. Meanwhile the multi-accessing nodes can make each transaction transparency for each node. In another way, the Blockchain is an ideal place to store claims to authorship without a central authority to censor, take down or potentially tamper with original work.
