态势感知对于安全和可持续的城市环境至关重要。虽然视频物联网（IoVT）的广泛部署能够有效监控智慧城市的镜头，但它也吸引了攻击者和滥用者。注入物联网的虚假信息可能误导城市管理部门、政策制定者和应急响应人员，并导致灾难性后果。及时验证来自广泛部署的iot设备的每个视频流是非常具有挑战性的。本文提出了一种区块链增强视频输入认证（BEVA）方案，作为一种边缘服务来对抗智能物联网系统的视觉层攻击，如在线假视频注入和离线视频流篡改攻击。BEVA方案利用嵌入在视频记录中的电子网络频率（ENF）作为在线假帧检测的环境指纹。区块链集成为支持分散的安全网络基础设施，它为基于enf的身份验证方案提供了不可变、可跟踪和可审计的分布式分类账，而不依赖于第三方信任机构。这种设计安全的解决方案有效地为现代智慧城市的物联网提供信任和安全服务。
Situational awareness is essential for a safe and sustainable urban environment. While the wide deployment of Internet of Video Things (IoVT) enables efficient monitoring of the footage of the Smart Cities, it also attracts attackers and abusers. Disinformation injected into the IoVT can mislead the city administrations, policy makers, and emergency responders, and lead to disastrous consequences. It is very challenging to timely authenticate each video stream from pervasively deployed IoVT devices. This article presents a Blockchain Enhanced Video input Authentication (BEVA) scheme as an edge service to fight against the visual layer attacks on smart IoVT systems such as online false video injection and offline video streams tampering attacks. The BEVA scheme leverages the electrical network frequency (ENF) embedded in video recordings as an environmental fingerprint for online false frame detection. Blockchain is integrated to enable a decentralized security networking infrastructure, and it empowers an immutable, traceable, and auditable distributed ledger for ENF-based authentication scheme without relying on a third-party trust authority. This secure-by-design solution efficiently provides trust and secure services in IoVT in modern Smart Cities.
