If David Cameron is re-elected as British Prime Minister in May, he plans to introduce legislation that will get rid of all that pesky security that prevents the law enforcement agencies from snooping on secure communications.
He, and his Home Secretary Theresa May, think it would be a good idea if people didn't use secure messaging systems that use end-to-end encryption. And so they want to outlaw products and services that don't provide a way for the UK government to sneak a peek at what you're saying to eachother.
This - understandably - has drawn quite a lot of concern from those people of a technical bent. But that's a debate for a whole different article...
... what I need your help with today is this.
If Cameron is re-elected, and he manages to push his plans through Parliament, it's going to be important for people to know which products they are allowed to use and which they're not allowed to use.
And that's where you come in.
Can you design a logo stamp for UK government-approved (in)secure messaging apps and services? I think it would save a lot of time if we could quickly tell which ones are on the side of law and order, and which are mischievously trying to keep their users' information private.
If you can design a logo, or an acronym, or even a jingle, send it to me at with the subject line of "Here's what I picture when I think of David Cameron's backdoor" and I will publish the best.
No prizes, other than the glory and adoration of the internet.
Thanks very much for taking part, and thanks to Quentyn Taylor who came up with the idea on Twitter.
