1. Meet Paul Kane.
The British father-of-two holds one of just seven keys which can help keep a major online directory secure.
The keyholders have been put in charge of protecting the domain name system, DNS, which is responsible for IP addresses.
2. Together their keys create a “master key”, used to make sure the DNS is secure.
Their aim is to make sure entries are legitimate and highlight fake web addresses which could be used for hacking or fraud purposes.
