Uber released a technical map of its computer and communications systems and is inviting hackers to find weaknesses in exchange for cash. While so-called "bug bounties" are not new, as many companies are making computer code public in order to make their systems more secure.

Uber's “"reasure Map" details the ride-hailing company's software infrastructure, identifies what sorts of data might be exposed inadvertently and suggests what types of flaws are the most likely to be found.

"We’re wrapping up a lot of information and posting that to level the playing field so that it could be as easy for outside researchers to find flaws as us," said Collin Greene, manager of security engineering at Uber.

"That’s a level of confidence that you have not seen too many closed-source software companies take in the past, and I’m really hopeful that others will follow suit," said Alex Rice, chief technology officer at HackerOne, which is managing Uber’s bounty program.
