Blippar wants your face in its app

Media captionWATCH: App recognises Rory

Ever seen someone across a crowded room and struggled to remember who they are? Well now there's an app which would allow you to fit the face to a name.

Blippar, the augmented reality business, is adding facial recognition to its app. Some will find that cool, others will see it as a creepy invasion of privacy.

At the moment the Blippar app gives you information about all kinds of objects when you point your smartphone's camera at them - it will identify famous paintings for example, or provide advertising content when you point it at a product.

Now the app will also recognise people - in real life or in photos and videos.

Blippar's co-founder Omar Tayeb gave me a demonstration, pointing the app at magazine pictures of Michael Fassbender and Hillary Clinton, then at a TV interview with Boris Johnson. In each case, the app recognised the faces and provided information about them - their social media profiles and Wikipedia entries.

He explained that Blippar had made more than 70,000 "public figures" recognisable by the app. I was rather surprised when he pointed the phone at me to find I was among them.

On this week's Tech Tent we travel to Slush, one of the most relaxed and vibrant technology events you will find anywhere in the world. It is held in almost total darkness in a huge exhibition hall in Finland's capital Helsinki and feels more like a music festival than a conference.

Nevertheless, with hundreds of startups mingling with established businesses, it is a great place to take the temperature of Europe's tech scene. From the founders of Spotify and Supercell, to the president of tiny but digitally pioneering Estonia, to some big names from Silicon Valley, there were all kinds of perspectives on the state of the tech business in uncertain times.

Tech Tent: The promise and perils of data


Big data. It's one of the tech cliches of the age. The idea that the torrent of data now being created can be processed in all sorts of clever ways with life-changing implications.

British insurers: 'Give us driverless car data'

Media captionThe confusion caused by driverless cars

Driverless car technology seems to be advancing at breakneck speed - but the changes this will mean for the rules of the road are proceeding at a slower pace.

Now the insurance industry is calling on carmakers to provide more data showing who was at fault in accidents involving driverless vehicles. The insurers say drivers need to be able to prove that they're not at fault if the technology goes wrong.

Tech Tent: Truth and hate in an online world

Rory Cellan-Jones

All of a sudden, some of the great names of the digital age are facing a crisis. Google, Facebook and Twitter have always seen themselves as more than mere businesses - they believe they are on a mission to make our lives better.

Now, in the bitter aftermath of America's presidential election, they stand accused of becoming vehicles of lies and hatred rather than civilised debate.
