Around the world, governments are planning, or have already begun, collecting data about their citizens’ use of mobile communications & the Internet. In most cases, they do not plan to capture the content of phone calls, emails or web pages: merely metadata. E.g. calls who, where from, who sends emails to whom, addresses of web pages visited. This metadata will be available to authorities without a warrant.
“It’s only metadata,” is commonly heard.
This raises two questions:
1. If metadata is of no importance, why do authorities wish to collect it?
2. Just what information can be gleaned from metadata?
In Australia, metadata collection & retention for two years, became compulsory on 13 October 2015. An employee of the ABC (Australian Broadcasting Corporation) acquired a copy of his metadata from his mobile carrier & made it available to the public to see what they could find out about him. This is what they found:
