child abuse, terrorism@
WASHINGTON, Oct 3 (Reuters) - The United States and allies are seizing on Facebook Inc's plan to apply end-to-end encryption across its messaging services to press for major changes to a practice long opposed by law enforcement, saying it hinders the fight against child abuse and terrorism.
The United States, the United Kingdom and Australia plan to sign a special data agreement on Thursday that would fast track requests from law enforcement to technology companies for information about the communications of terrorists and child predators, according to documents reviewed by Reuters.
The agreement will be announced alongside an open letter to Facebook and its Chief Executive Mark Zuckerberg, calling on the company to suspend plans related to developing end-to-end encryption technology across its messaging services.
Child predators have increasingly used messaging applications, including Facebook's Messenger, to exchange explicit images and videos.
Speaking at an event in Washington on Wednesday, Associate Attorney General Sujit Raman said the National Center for Missing and Exploited Children received more than 18 million tips of online child sex abuse last year, over 90% of them from Facebook.
He estimated that up to 75% of those tips would "go dark" if social media companies like Facebook were to go through with encryption plans.
In practice, the bilateral agreement would empower the UK government to directly request data from U.S. tech companies, which remotely store data relevant to their own ongoing criminal investigations, rather than asking for it via U.S. law enforcement officials.
The effort represents a two-pronged approach by the United States and its allies to pressure private technology companies while making information sharing about criminal investigations faster.
A representative for the U.S. Department of Justice declined to comment.
The letter addressed to Zuckerberg and Facebook comes from U.S. Attorney General William Barr, UK Secretary of State for the Home Department Priti Patel and Australian Minister of Home Affairs Peter Dutton.
"Our understanding is that much of this activity, which is critical to protecting children and fighting terrorism, will no longer be possible if Facebook implements its proposals as planned," the letter reads.
"Unfortunately, Facebook has not committed to address our serious concerns about the impact its proposals could have on protecting our most vulnerable citizens."
WhatsApp's global head Will Cathcart wrote in a public internet forum https://news.ycombinator.com/item?id=21100588 on Saturday that the company "will always oppose government attempts to build backdoors because they would weaken the security of everyone who uses WhatsApp including governments themselves."
That app, which is already encrypted, is also owned by Facebook. (Reporting by Joseph Menn and Katie Paul in San Francisco and Christopher Bing in Washington; Editing by Lisa Shumaker)
