Tristan: 当前AI技术进步使得真假难辨，深度伪造技术被用于诈骗、勒索和影响选举等活动，现有AI检测工具不可靠。我们需要更好的工具来辨别网络上的真假信息。 我今天很高兴邀请到Oren Etzioni来谈论一个新的AI生成内容检测工具。随着AI技术的不断进步，区分现实与虚幻的能力将变得越来越重要。深度伪造技术已经被用于诈骗、勒索和影响选举等活动，并且有很多网站声称能够检测内容是否由AI生成，但这些网站的可靠性非常低。 Oren Etzioni: 深度伪造技术对社会和经济具有潜在的重大影响，尤其是在政治领域，可能影响选举结果。我们开发的Truemedia.org AI检测工具旨在帮助媒体机构、事实核查员和普通公众识别AI生成的虚假信息。 目前AI领域的投资严重失衡，对AI安全性的投入不足。Truemedia.org的AI检测工具由Gerrit Kemp资助，旨在为媒体机构、事实核查员和普通公众提供免费服务。该工具使用简单，用户可以通过上传图片、视频或音频，或粘贴社交媒体链接进行检测。我们的工具通过整合多个深度伪造检测工具和自有模型进行分析，以提高检测准确率。我们还分析视频的语义信息，并进行反向搜索以查找图像是否在其他地方出现过。我们甚至可以分析唇形同步技术生成的视频中音频和视频之间细微的差异来检测伪造。我们的工具准确率超过90%，但仍存在误差，用户界面会提示用户注意这一点。 大型社交媒体平台对实施深度伪造检测技术缺乏经济激励，因此需要立法干预。他们认为自己没有责任告知公众AI生成的虚假信息。提高深度伪造检测的准确率，并对可疑内容进行标记，而非直接删除。解决AI深度伪造问题需要政府监管、技术工具和公众意识的共同努力。提高公众的媒体素养，增强人们对信息的辨别能力，是解决AI深度伪造问题的重要途径。

Deep Dive

Chapters
The rise of sophisticated AI technologies has made it increasingly challenging to distinguish between authentic and synthetic media. This poses significant risks to society and democracy. Oren Etzioni, CEO of TrueMedia.org, discusses the creation of a new tool to address this problem.
  • Deepfakes are used for scams, extortion, and election influence.
  • Many existing AI detection tools are unreliable.
  • TrueMedia.org offers a state-of-the-art AI detection tool.

Shownotes Transcript

Social media disinformation did enormous damage to our shared idea of reality. Now, the rise of generative AI has unleashed a flood of high-quality synthetic media into the digital ecosystem. As a result, it's more difficult than ever to tell what’s real and what’s not, a problem with profound implications for the health of our society and democracy. So how do we fix this critical issue?

As it turns out, there’s a whole ecosystem of folks to answer that question. One is computer scientist Oren Etzioni, the CEO of TrueMedia.org), a free, non-partisan, non-profit tool that is able to detect AI generated content with a high degree of accuracy. Oren joins the show this week to talk about the problem of deepfakes and disinformation and what he sees as the best solutions.

CLARIFICATION: Oren said that the largest social media platforms “don’t see a responsibility to let the public know this was manipulated by AI.” Meta has made a public commitment to flagging AI-generated or -manipulated content. Whereas other platforms like TikTok and Snapchat rely on users to flag.
