项目摘要

Objective: The objective of this project is to investigate the scientific and technological foundations on time, location and integrity of sensor recordings, by exploiting novel intrinsic fingerprints in the environment. An example is the small random-like fluctuations of the electricity frequency known as the Electric Network Frequency (ENF). These environmental fingerprints reflect the attributes and conditions of the power grid and become naturally "embedded" into video, audio or other types of sensor signals at the time of recording. They carry time and location information and may facilitate integrity verification of the primary sensing data. Answering questions about the time, location, and integrity of sensor recordings find important applications in crime solving, counter-terrorism, journalism, infrastructure monitoring, smart grid management, and other commercial operations.Intellectual merit: The intellectual merit lies on exploring the nearly unchartered research area of forensic evidences in the environment, by drawing synergy across multiple disciplines including signal processing, machine learning, sensor circuits and systems, power engineering, and information forensics/security. The research exploration and technology development of this project are transformative and interdisciplinary in nature. Broader impacts: The broader impacts are two folds: through engaging students, especially female and under-represented ones, in exploratory research, the project's seamless integration of research with education and outreach will prepare the future generation of engineering workforce with interdisciplinary strength; through new technologies and tools developed to advance information forensics, the project has a high potential to benefit a number of applications of global and societal importance.

目的：该项目的目的是通过利用环境中新型的内在指纹来研究传感器记录的时间，位置和完整性的科学和技术基础。一个例子是电频率的小小型随机波动，称为电网络频率（ENF）。这些环境指纹反映了电网的属性和条件，并在录制时自然地“嵌入”到视频，音频或其他类型的传感器信号中。它们携带时间和位置信息，并可能促进主传感数据的完整性验证。回答有关传感器记录的时间，位置和完整性的问题在犯罪解决，反恐，新闻业，基础架构监控，智能网格管理和其他商业操作中都有重要的应用。Intelltectual功绩：智力优点在于探索近乎无用的跨环境的跨度跨度跨度的跨度跨度跨度跨度的跨越跨度的研究，包括跨度的跨度跨度，包括跨度的循环，包括跨度的跨度范围，包括跨度的跨度范围，这些系统跨越了Synerge，绘制了多个机器的范围。工程和信息取证/安全。该项目的研究探索和技术开发本质上是变革性和跨学科的。更广泛的影响：更广泛的影响是两个方面：通过吸引学生，尤其是女性和代表性不足的学生，在探索性研究中，该项目将研究与教育和外展的无缝融合将使未来一代的工程劳动力为跨学科的力量做好准备；通过开发出旨在推进信息取证的新技术和工具，该项目具有很大的潜力，可以使许多全球和社会重要性的应用受益。
