While facial recognition technology is often criticized for invading people’s privacy, smartphone messaging company Snapchat is looking at how it can use the same technology to enhance the privacy of its users.
Snapchat has filed a patent for a technology that automatically modifies a photo and restricts its distribution according to the privacy settings of the photo’s subjects.
How it works
Facial recognition is very different to the object recognition used in Snapchat lenses. Object recognition simply uses algorithms to understand the general nature of objects within a photo so users can add real-time special effects and sounds to them.
With a new facial recognition feature, Snapchat users would be able to dictate how and where images of them are displayed. Here’s how it would work:
- You take a photo.
- Snapchat scans it to work out if any of the faces belong to its users.
- If any do, it checks their privacy settings.
- Their face or body would be altered according to their privacy setting.
- The modified image would then be shared according to the subjects’ privacy settings.
For facial recognition to work, Snapchat would need to store images of all users that sign up to the feature – as a reference image to compare photos against.
What this means
Business Insider explores the patent and its implications in a little more depth, noting that big tech companies like Snapchat tend to file a lot of patents and only some of them end up being developed.
So for now the prospect of using facial recognition to protect privacy is nothing more than an interesting idea.
The patent application does suggest that Snapchat is actively exploring possible uses for facial recognition technology, something that Business Insider points out might help it close a gap on rivals Facebook and Google.
Facebook and Google’s technology platforms naturally turn up a wealth of information on users that helps them sell targeted advertising, but Snapchat’s doesn’t.
By developing facial recognition, even for the purpose of safeguarding users’ privacy, Snapchat will give itself a way to identify specific individuals and the relationships between them – things that can be used to improve targeted advertising.
Evolving its technology in this way would go against the way Snapchat is currently positioning itself. CEO Evan Spiegel gave the prospect of targeted advertising a clear thumbs down in an interview last month:
Spiegel said Snapchat “really care[s] about not being creepy,” which is why the business chose to concentrate on the context of advertising and where it sits, rather than targeting.
For users who recall Snapchat’s shaky beginnings, that assurance of non-creepiness is welcome but may not calm the speculation.
2 comments on “Snapchat turns facial recognition technology on its head”
What is the default for non users of the service?
The way this is written, is sound like I would have to register an account with Snapchat, and lock down the privacy settings in order to prevent my picture from being distributed, even if I had no other reason to use the service.
One quick comment and a question
– Snapchat would presumably store the image (not ideal in my mind as someone could possibly hack them and alter my/your privacy settings, steal/borrow the image to reverse engineer the technology, etc)
And “What could possibly go wrong?”
