Abstract
进入大数据时代后,互联网应用和信息服务全面普及,大量的个人敏感生物信息被收集整理,导致隐私泄露风险增加;事件相机作为新型的生物启发式传感器,具有低延迟、高动态、无纹理等特性,可为解决数据端隐私保护问题提供全新的技术途径,也因其光敏工作原理而适用于家庭监控等私人场景。本文从大数据时代的隐私泄露问题、事件相机在隐私保护中的优势两方面,深入分析了事件相机用于隐私保护的研究背景;系统梳理了基于人脸模板的隐私保护、基于去识别的隐私保护、基于点云混沌加密的隐私保护等传统的敏感生物信息隐私保护方法,包括行人重识别、手势识别、面部分析在内的面向隐私保护的事件感知方法以及两大类方法的研究进展。进一步总结了强度图像重建、图像修复、视频重建等基于事件流的图像重建与修复新进展,完成了基于6 种算法的图像重建及其结果分析,证明已有重建算法对纹理信息的恢复能力有限,反向验证了基于事件相机的隐私保护技术可行性。针对事件相机未来的规模化应用,提出了降低硬件成本、改进算法网络、从市场角度推动等发展建议,以期为事件相机的隐私保护深化应用提供基础参考。
