在这个演示中，我们介绍了E-Witness，一个使用区块链技术来证明通过智能手机捕获的数字证据的完整性和时空属性的系统。该系统由一个智能手机应用程序组成，该应用程序计算从手机摄像头拍摄的图片或视频的强大哈希值，一个位置证明服务和一个公共区块链，该区块链包含分类账条目以保存证据文件的哈希值和位置证书。在这个过程中，人类证人可以保持匿名。（以任何方式）接收证据的调查人员可以通过查询区块链来验证证据的完整性和时空声明。
In this demo we present E-Witness, a system that uses blockchain technology to prove the integrity and spatio-temporal properties of digital evidence captured through a smart-phone. The system consists of a smart-phone application that computes robust hash of pictures or videos taken from the phone camera, a location attestation service and a public blockchain which contains ledger entries to preserve the evidence file's hash and location certificate. The human witness can remain anonymous in this process. An investigator who receives the evidence (by any means) can verify the integrity and spatio-temporal claims of the evidence by querying the blockchain.
