Give social networks fake details, advises UK govt web security official

I suspect this was driven by frustration.

HMG are driving hard to push government to citizen interaction online to reduce costs and speed up the transactions. The financial transactions are a huge amount of money passing over the Internet leaving aside the serious duty of care they assume for vulnerable or at-risk citizens.

This relies on knowing who is driving the browser you're transacting with. when you're dealing with the entire population there are a lot of people who it's difficult to establish a valid identity for.

Knowledge-based authentication is the 'good enough' answer used by commercial providers but for a significant proportion of the population it's broken by their social network use and footprint.

Don't share every second of your life. Keep to yourself what you want private and share what you want public. No need to mess around with other identities.
