Facebook on Friday removed what it called a global network of more than 900 accounts, pages, and groups from its platform and Instagram that allegedly used deceptive practices to push pro-Trump narratives to about 55 million users. The network used fake accounts, artificial amplification, and, notably, profile photos of fake faces generated using artificial intelligence to spread polarizing, predominantly right-wing content around the web, including on Twitter and YouTube.

上周五,Facebook从其平台和Instagram上删除了一个称为全球网络的网络,该网络中包括900多个帐户,页面和群组,据称他们使用欺骗手段将特朗普的言论推向了约5500万用户。该网络(包括Twitter和YouTube上)使用伪造帐户,并且人为扩大,尤其是使用人工智能生成的虚假面孔的个人资料照片,主要传播右翼极端化内容。

It represents an alarming new development in the information wars, as it appears to be the first large-scale deployment of AI-generated images in a social network. In a report on the influence operation, researchers from disinformation groups Graphika and DFRLab noted that this was the first time they had seen the technology used to support an inauthentic social media campaign.

这代表着信息战中一个令人震惊的新发展,因为它似乎是社交网络中首次大规模部署AI生成的图像。权威报道称,研究者们指出他们从由Graphika和DFRLab提供虚假信息的组织中第一次发现用于支持虚假社交媒体活动的技术。

The images were used to enhance the authenticity of some of the 610 Facebook accounts, 156 groups, 89 pages, and 72 Instagram accounts associated with “The BL,” a digital news outlet that described itself as a “pure mountain spring, moistening the heart of every reader” on Facebook before it was removed

在这些图像在Facebook上被删除之前,是被用来加强与“ BL”相关的610个Facebook帐户,156个群组,89页和72个Instagram帐户中某些真实性,数字媒体称之为“纯净的山泉,滋润每个读者的心脏” 。 

Ostensibly a US-based media organization, The BL network's pages were operated by users in Vietnam and the US, who Facebook says made widespread use of fake accounts to evade detection and funnel traffic to its own websites. A report by Graphika and DFRLab researchers, found that the majority of The BL network's fake accounts were used to maintain a cluster of over 80 groups and pages promoting President Trump. The accounts acting as administrators for these pages—which boasted names such as “America Needs President Trump,” “Trump for America's President,” and “WE STAND WITH TRUMP & PENCE!”—were predominantly fake and created in Vietnam.

BL网络表面上是一家位于美国的媒体组织,其网页由越南和美国的用户操作,Facebook表示,BL的页面大量使用虚假帐户,以逃避对其网站的检测和访问。 在Graphika和DFRLab研究人员的一份报告中发现,BL网络的大多数虚假账户都用于维护由80多个团体和页面组成的集群,以宣传特朗普总统。这些页面的管理员帐户,其中以“美国需要特朗普总统”,“美国总统特朗普”和“我们支持特朗普与便士!”等名称为假,主要是在越南创建的。

“Fake accounts served as the administrators of Facebook groups, increased the membership numbers of those groups, liked posts on the Pages, and posted large quantities of content from TheBL-related assets,” the report notes. “This structure constituted a large-scale artificial amplification factory whose only observable function was to boost content from TheBL and, to a lesser extent, from the Epoch Times.”

报告指出:“虚假帐户充当了Facebook组的管理员,来增加组的成员数量,比如在网站上发布帖子,发布大量与BL资产相关的内容。” “这种结构构成了一个大型人工扩增工厂,其唯一显著的功能是宣扬BL的内容,并在较小程度上宣扬新纪元。”

Many of these accounts used profile pictures that researchers said appeared to be created using neural networks trained on images of real human faces to create photos of people that did not actually exist. Researchers from Graphika and DFRLab found 18 images of faces in profile photos used by The BL network that they said had likely been generated using generative adversarial networks.

研究人员们表示其中的许多账户所使用的个人资料照片似乎是由能被训练过的神经网络创建的,用真实人脸图像训练该网络,即可创建不存在的人的照片。研究者们在“Graphika和DFRLab”中发现有18张面部图像在BL网络中使用,认为这些照片很可能是使用对抗网络生成的。

While the technology is capable of creating passable fake faces, it has a few obvious tells that tipped the researchers off. It works largely by mimicking visual patterns, but doesn't understand human anatomy, and struggles with backgrounds and symmetrical features, like glasses or earrings.

尽管这项技术能够制造出合格的假脸,但研究者们仍然发现了一些明显的迹象。它主要是通过模仿视觉模式来工作的,但不了解人体解剖结构,并且与背景和对称图形(例如眼镜或耳环)作斗争。

The above image, from the Graphika report, was taken from the profile photo for “Alfonzo Macias,” an admin for one of the groups in The BL network. “Note the asymmetry in the glasses and also the poorly defined background,” the report says. “The authors checked this image with experts at the University Federico II of Naples, who assessed that this image was GAN-generated with 99.9 percent certainty.”

上图是Graphika报告中的图片,是BL网络中一个群组的管理员“ Alfonzo Macias”的头像照片。该报告说:“请注意眼镜的不对称性以及背景的清晰度不佳。” “作者与那不勒斯费德里科第二大学的专家核对了这张图像,他们评估了这张图像是由GAN生成的,具有99.9%的确定性。”
