But we believe it’s part of our broad responsibility to the communities we serve, so long as it’s consistent with the law and does not undermine the security of our products.
When it comes to encryption services, we know that working with governments can be controversial. WhatsApp’s response to an emergency request from law enforcement in Brazil helped rescue a kidnapping victim - and in Indonesia, it helped law enforcement prosecute a group spreading child exploitive imagery. And we plan to host more sessions in the coming months. To help them understand, WhatsApp has hosted a number of training sessions around the world, including in Europe and Brazil, for the police, judges and others. WhatsApp has shared these details to help law enforcement when we get valid legal requests to help them close in on a suspect. While we can’t access encrypted conversations, WhatsApp does have some limited personal information about users that they collect in order to provide their service. My work involves working with government and law enforcement agencies to help keep people safe. Working With Governments to Keep People Safe This constant auditing is another reason why decrypting certain conversations on behalf of governments, even if legal under local law, would not go unnoticed. And we rely on open source encryption protocols, encouraging people - and governments - to test the security of our systems. It’s why weakening any part of encryption weakens the whole security ecosystem. And proponents of so-called “backdoors” imagine a hidden way of bypassing encryption, somehow accessing only the conversations of suspected criminals or terrorists while continuing to protect everyone else.īut cybersecurity experts have repeatedly proven that it’s impossible to create any backdoor that couldn’t be discovered - and exploited - by bad actors. A report by the Electronic Frontier Foundation earlier this year identified an effort, likely by a foreign nation, to trick people into installing spoof versions of messaging apps for intelligence purposes. While some officials publicly acknowledge the benefits of end-to-end encryption, they simultaneously push for work-arounds that would allow them access to at least some information. In addition, changing our encryption practices would not stop bad actors from using end-to-end encryption since other, less responsible services are available. But there would be a clear trade-off without it: it would remove an important layer of security for the hundreds of millions of law-abiding people that rely on end-to-end encryption. And now that I’m at Facebook, which owns WhatsApp, I hear from government officials who question why we continue to enable end-to-end encryption when we know it’s being used by bad people to do bad things. No one can intercept the communications.įrom my law enforcement days, I understand the frustration of this technology, especially when a threat may be imminent. For added protection, every message you send has its own unique lock and key. End-to-end encrypted messages are secured with a lock, and only the sender and recipient have the special key needed to unlock and read them.
Yet I feel strongly that society is better off with it.Įnd-to-end encryption is used in all WhatsApp conversations and can be opted into in Messenger. So I have experienced the trade-offs of encryption first hand. But it could also create challenges in obtaining evidence. It made it possible to communicate securely within our own organization as well as other agencies and sources in the field. My job was to work with law enforcement agencies around the world - including Interpol and Europol - to study how criminals communicate with each other. I joined Facebook after two decades with the British National Crime Agency working on international investigations. But like most technologies, it also has drawbacks: it can make it harder for companies to catch bad actors abusing their services or for law enforcement to investigate some crimes. And by end-to-end encrypting sensitive information, a cyber attack aimed at revealing private conversations would be far less likely to succeed. It gives citizens in repressive regimes a lifeline to human rights advocates. It helps journalists communicate with sources without governments listening in. It lets patients talk to their doctors in complete confidence.
