I-Corps: Blockchain-backed system that establishes the provenance of digital images and videos

这个i-Corps项目的更广泛的影响/商业潜力探索了一种媒体认证技术的翻译。在日益数字化的世界里，这项技术允许任何人立即检查图像或视频的真实性。这项技术可以用于许多应用，如视频记录的验证、版权管理、供应链管理、监管链流程和其他用途。这个i-Corps项目推动了区块链支持技术的发展，以提供事件发生的可视证据。技术前端允许对图像和/或视频进行受控捕获，计算媒体的唯一签名，并收集日期、时间、所有权等元数据。和设备标识。在后端，区块链将唯一的签名和元信息放置在三分之二区块链参与者一致承诺的区块中。区块链共识保证了区块一旦提交，媒体的不变性。认证的接收者可以从文件中重新计算唯一签名，在区块链中搜索匹配的区块，获得媒体可信的证据，并立即获得日期和时间等元数据。内容创建者可以匿名，也可以验证版权信息。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this I-Corps project explores translation of a media authentication technology. In an increasingly digitized world, this technology allows for anyone to instantly check the authenticity of an image or video. This technology can be used in a number of applications, such as verification of video recordings, copyright management, supply chain management, chain-of-custody processes, and other uses. This I-Corps project advances the development of blockchain-backed technology to provide a visual proof of occurrence of an event. The technology frontend allows a controlled capture of images and/or videos, computes a unique signature of the media, and collects metadata such as date, time, ownership. and device identification. In the backend, a blockchain places the unique signature and meta information in a block committed upon consensus by two-thirds of the blockchain participants. Blockchain consensus guarantees the immutability of the media once the block is committed. A certified recipient can re-compute the unique signature from the file, search the blockchain for a matching block, obtain proof that the media is authentic, and instantly obtain the metadata, such as the date and time. The content creator could be anonymized or copyright information can be validated.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
