With the exponential increase in cybercrimes in recent years, the need for Computer Forensics and Digital Evidence (CFDE) expertise is rapidly growing. A qualified CFDE professional needs to have deep knowledge of digital forensic evidence identification, acquisition, and examination, as well as the ability to present and explain digital forensic evidence in courtrooms. However, there are major barriers to instilling the core knowledge of CFDE and practice of cyber investigation techniques in a diverse body of interested students. For example, a systematic approach for collecting, organizing, and analyzing digital forensic evidence is lacking. This project will engage novel interdisciplinary perspectives, including artificial intelligence (AI), cybersecurity, criminal justice, and computer science to re-examine the emerging CFDE field with a formal approach. This project will then explore visualized and explainable AI to improve students’ learning experience in digital forensics education at Minority-Serving Institutions (MSIs) including Historically Black Colleges and Universities (HBCUs).The project brings together faculty from the University of Baltimore, an MSI, Bowie State University, one of the oldest HBCUs in Maryland, and the University of Missouri Kansas City, who have synergistic expertise in digital forensics, cybersecurity, AI, law, and computer science. The project will leverage graph-based AI models to provide students with visualized depictions of forensic evidence, the patterns of evidence, and the connections among the evidence. It will also explore explainable AI to support the development of forensic evidence that is accountable and presentable to courts, and develop AI-aided CFDE instructional materials. The project will address research questions at the intersection of AI, CFDE, and education including the following: (a) How do graph-based models store, retrieve, and present digital forensic evidence? (b) How do graph-based AI models discover new evidence and to what extent should we trust AI-discovered evidence/patterns? (c) How can knowledge and techniques of AI-assisted investigation be infused into CFDE instructional materials, and to what extent do the materials improve students’ learning experiences? Learning materials will be made available to both the CFDE and data science communities. This project is supported by a special initiative of the Secure and Trustworthy Cyberspace (SaTC) program to foster new, previously unexplored, collaborations between the fields of cybersecurity, artificial intelligence, and education. The SaTC program aligns with the Federal Cybersecurity Research and Development Strategic Plan and the National Privacy Research Strategy to protect and preserve the growing social and economic benefits of cyber systems while ensuring security and privacy.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.

随着近年来网络犯罪呈指数级增长，对计算机取证和数字证据(CFDE)专业知识的需求迅速增长。一名合格的CFDE专业人员需要对数字法医证据的识别、获取和审查有深入的了解，以及在法庭上展示和解释数字法医证据的能力。然而，在向不同的感兴趣的学生群体灌输CFDE的核心知识和实践网络调查技术方面存在重大障碍。例如，缺乏收集、组织和分析数字法医证据的系统方法。该项目将采用新颖的跨学科视角，包括人工智能(AI)、网络安全、刑事司法和计算机科学，以正式的方法重新审视新兴的CFDE领域。该项目将探索可视化和可解释的人工智能，以改善学生在少数族裔服务机构(MSI)(包括历史上的黑人学院和大学(HBCU))的数字取证教育中的学习体验。该项目汇集了来自巴尔的摩大学、MSI、鲍伊州立大学(马里兰州最古老的HBCU之一)和密苏里堪萨斯城大学的教师，他们在数字取证、网络安全、人工智能、法律和计算机科学方面拥有协同专业知识。该项目将利用基于图形的人工智能模型为学生提供法医证据、证据模式以及证据之间的联系的可视化描述。它还将探索可解释的人工智能，以支持开发对法院负责和可向法院出示的法医证据，并开发人工智能辅助的CFDE教学材料。该项目将解决人工智能、CFDE和教育交叉领域的研究问题，包括以下内容：(A)基于图形的模型如何存储、检索和呈现数字法医证据？(B)基于图形的人工智能模型如何发现新的证据，以及我们应该在多大程度上信任人工智能发现的证据/模式？(C)如何将人工智能辅助调查的知识和技术灌输到CFDE教学材料中，以及这些材料在多大程度上改善了学生的学习体验？将向CFDE和数据科学界提供学习材料。该项目得到了安全和值得信赖的网络空间(SATC)计划的一项特别倡议的支持，该计划旨在促进网络安全、人工智能和教育领域之间新的、以前从未探索过的合作。SATC计划与联邦网络安全研究和发展战略计划和国家隐私研究战略保持一致，以保护和维护网络系统日益增长的社会和经济效益，同时确保安全和隐私。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。
