Facebook lays out challenges of letting users take their data to other platforms

FACEBOOK Inc. has promised regulators that it will protect users’ privacy and give them the right to take their data where they choose. Now the company is trying to figure out how it can do both.

In a white paper issued Wednesday, the social-media giant outlines how those two big mandates are potentially in conflict. The company said it is seeking outside input on how to deliver on both objectives and get a consensus on how the industry will handle such matters going forward.
