Proposal: 0716203Shih-Fu ChangColumbia UniversityCT-ISG: Trustworthy Media: Blind Passive Media Forensics for Content Integrity VerificationAbstract:Digital audio-visual content can nowadays be modified and simulated with unprecedented realism. In response to the challenge of malicious media manipulation, we propose to develop new theories, methods, and a comprehensive suite of tools that can be used to verify content integrity in both audio and visual modalities at multiple levels under diverse contexts. The results will have significant impacts in scientific areas as well as many practical applications of national interest, such as trustworthy news reporting, surveillance security, intelligence gathering, criminal investigation, financial transactions, and medical information management. Our efforts will be based on an important paradigm, called blind passive media forensics, which fundamentally differs from conventional approaches using cryptographic signatures and watermarking. The proposed methods extract latent, unique signatures from the signals and sensing devices to detect tampering anomalies, so that verification requires only the media content at hand without any additional information or preparation. Specifically, we propose a systematic framework for device signature consistency checking and a joint multi-modal approach for verifying media integrity. We will also analyze various attack scenarios, construct rigorous benchmark datasets and performance metrics, and take proactive steps in disseminating results and promoting awareness of this critical area through public testing of online systems.

提案：0716203Shih-Fu Changcolumbia Universityct-ISG：值得信赖的媒体：盲目的被动媒体取证内容的内容完整性verification verificationAbstract：如今，可以通过前所未有的现实主义进行修改和模拟。为了应对恶意媒体操纵的挑战，我们建议开发新的理论，方法和全面的工具套件，这些工具可用于在不同层面上在多个层面上验证音频和视觉方式中的内容完整性。结果将对科学领域以及许多国家利益的实际应用产生重大影响，例如值得信赖的新闻报道，监视安全，情报收集，刑事调查，金融交易和医疗信息管理。我们的努力将基于一个重要的范式，称为盲目的被动媒体取证，这与使用加密标志和水印的常规方法从根本上有所不同。所提出的方法从信号和传感设备中提取潜在的独特签名来检测篡改异常，因此验证仅需要手头的媒体内容，而无需任何其他信息或准备。具体而言，我们为设备签名一致性检查和一种验证媒体完整性的联合多模式方法提出了一个系统的框架。我们还将分析各种攻击方案，构建严格的基准数据集和性能指标，并采取积极的步骤来传播结果，并通过公开对在线系统进行公开测试来促进对这一关键领域的认识。
