Facebook boss Mark Zuckerberg believes secure, private messaging services will become more popular than open platforms.
According to him, "privacy gives people the freedom to be themselves and connect more naturally, which is why we build social networks."
In a blog, Mr Zuckerberg outlined his vision to transform Facebook into a "privacy-focused platform."
"Facebook and Instagram have helped people connect with friends, communities, and interests in the digital equivalent of a town square," said the founder of Facebook.
"But people increasingly also want to connect privately in the digital equivalent of the living room," he added.
Mr Zuckerberg said he wanted to develop the social media network into one focused around privacy, reducing permanence and secure data storage.
As part of his privacy goals, he said Facebook would not "store sensitive data in countries with weak records on human rights like privacy and freedom of expression."
Mr Zuckerberg added that encrypted messaging will also create scope for new business tools, especially ones around online payments and commerce.
