用于认证多媒体新闻内容以防御假新闻的Web基础设施
A Web Infrastructure for Certifying Multimedia News Content for Fake News Defense
AI总结：
提出基于公钥基础设施的Web方案，让新闻组织用私钥对多媒体新闻数字签名，用户通过浏览器扩展验证背书来源，从而防御假新闻。
摘要：
在处理被篡改的多媒体新闻内容（也称为假新闻）时，我们提出了一种基于现有公钥基础设施（PKI）的即用型方案，作为新的假新闻防御范式。该方案使新闻组织能够认证/背书有新闻价值的多媒体新闻内容，并将此信任信息安全、便捷地传递给最终用户。新闻组织可使用我们的程序，用其私钥对多媒体新闻内容进行数字签名。通过安装浏览器扩展，最终用户能够轻松验证某条新闻内容是否已被背书以及由哪个组织背书。是否信任该新闻或背书的新闻组织完全取决于最终用户。我们方案的基本原则是：假新闻迟早会被大众识别为虚假内容，而新闻组织在背书新闻内容时需将其长期声誉押在上面。
英文摘要：
In dealing with altered multimedia news content, also referred to as fake news, we present a ready-to-deploy scheme based on existing public key infrastructure as a new fake news defense paradigm. This scheme enables news organizations to certify/endorse a newsworthy multimedia news content and securely and conveniently pass this trust information to end users. A news organization can use our program to digitally sign the multimedia news content with its private key. By installing a browser extension, an end user can easily verify whether a news content has been endorsed and by which organization. It is totally up to the end user whether to trust the news or the endorsing news organization. The underlining principles of our scheme are that fake news will sooner or later be identified as fake by general population, and a news organization puts its long-term reputation on the line when endorsing a news content.
