SaTC: CORE: Medium: Collaborative: Cryptographic Provenance for Digital Publishing

许多在线新闻内容缺乏关于其出处的可验证信息，包括谁撰写和发布了它，什么组织分发了它，以及何时发布。如果没有出处，读者就无法保证他们访问的内容来自指定的出版商。读者也无法确定内容是何时发布的，或者是否被修改或更新。该项目将开发一个新的系统，以加密方式验证数字新闻内容的来源。该系统包括将数字内容归属于其出版商、确认其出版日期并显示其修订历史的工具。该系统将提高出版商的可信度，帮助读者追究出版商的责任，并帮助档案管理员保存正确的数字内容。最终，该系统将提高在线信息生态系统的安全性和可信度。该项目将通过设计，开发和分发数字媒体的新技术认证机制来推进知识。该项目的工作包括设计、测试和实现加密工具，以确保现代数字出版系统的安全。该团队将密码学与用户界面设计相结合，以创建一个原型，准确和可验证地传达出处和完整性保证。通过应用密码学、标准开发和用户体验研究的迭代开发，研究人员将创建工具，为信息真实性、应用密码学和人机交互方面的重大研究挑战提供解决方案。该系统将能够验证出版日期和版本历史，并检查图像和社交媒体帖子等内容的嵌入元素的完整性。通过让用户参与新发布协议的设计，这项工作将弥合以用户为中心的真实性概念与加密概念之间的差距。这项工作将促进一般和专业出版商创造和采用这些技术，并将减轻安全威胁，提高公众可以信任在线新闻来源和内容的保证。该奖项反映了NSF的法定使命，并已被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

Much online news content lacks verifiable information about its provenance, including who wrote and published it, what organization distributed it, and when it was published. Without provenance, readers have no guarantees that the content they accessed originated with the stated publisher. Readers also cannot be sure when the content was published, or if it has been altered or updated. This project will develop a new system to cryptographically verify the provenance of digital news content. This system includes tools to attribute digital content to its publisher, confirm its publication date and show its revision history. This system will improve publisher credibility, help readers hold publishers accountable, and help archivists preserve correct digital content. Ultimately, the system will improve the security and trustworthiness of the online information ecosystem. This project will advance knowledge through the design, development, and distribution of novel technical authentication mechanisms for digital media. This project's work involves designing, testing, and implementing cryptographic tools to secure modern digital publication systems. The team will integrate cryptography with user interface design to create a prototype that accurately and verifiably conveys provenance and integrity guarantees. Through iterative development of applied cryptography, standards-development, and user-experience research, the researchers will create tools to provide solutions to significant research challenges in information authenticity, applied cryptography, and human-computer interaction. The system will enable verification of publication dates and version history, and check integrity of embedded elements of content such as images and social media posts. By engaging users in the design of the new publishing protocol, this work will bridge the gap between user-centric and cryptographic notions of authenticity. The work will facilitate the creation and adoption of these technologies by general and specialized publishers, and will mitigate security threats and improve assurance that the public can trust online news sources and content.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.
