Input: By Chris FoxTechnology reporter Facebook's critics have laughed at the suggestion. Until now, it has been encouraging people to share more, scooping up buckets of personal data and using it to rake in advertising cash. Will it really change, when it makes so much money from us over-sharing? What has Facebook proposed? In a 3,200-word blog, Facebook's chief executive, Mark Zuckerberg, said "privacy-focused communications" would become more important than open social networks in the future. In some countries, this is already the case. Mr Zuckerberg said Facebook was exploring: However, he stressed that the option to post publicly would remain, as it let people discover "new people, ideas and content" and gave people a voice. He also said the company would not build data centres in countries with a "track record of violating human rights". How will this help Facebook? A move to make Facebook more privacy-focused may help restore some public trust in the platform, which has been plagued by a year of privacy scandals and data breaches. Adding end-to-end encryption to all private messages would mean Facebook could not be compelled by governments to hand over its users' personal messages, because it does not have a copy. Mr Zuckerberg said an "inherent trade-off" of encrypted messaging was that criminals could hide activity such as terrorism or child abuse. But, he said, the company was improving its ability to "stop bad actors across our apps by detecting patterns of activity". How will Facebook make money from this? Facebook makes most of its money by letting advertisers target their messages at very specific audiences. People share so much on Facebook that the company can build a detailed picture of their age, location, political views, likes, interests and more. Investing in privacy may: The company is also exploring ways that it can charge businesses to contact people on its messaging apps. "I understand that many people don't think Facebook can or would even want to build this kind of privacy-focused platform," said Mr Zuckerberg. "Frankly, we don't currently have a strong reputation for building privacy protective services and we've historically focused on tools for more open sharing. "But we've repeatedly shown that we can evolve to build the services that people really want, including in private messaging and stories." The changes would take "several months" to roll out, he added. In May 2018, it promised to launch a "clear history" feature that would let people delete personal data Facebook had scooped up. The feature has still not launched.
