On the one hand, I can totally understand that there is a difference between recognizing a face and recognizing your face. Algorithms that recognize a face are really easy to implement now.

On the other hand, though, why should a vending machine need to recognize a face? So it shuts off it's lighting when no one is looking at it? I'm not sure if there is any practical benefit besides some project manager justifying a new feature with buzzword-compliant tech.

I believe the company when they say there is nothing problematic here, but they deserve the bad press for thinking it would be a good idea in the first place.

Their corporate website mentions that they use the data for marketing purposes. Whatever type of face they see - e.g. male or female, large or skinny, etc. - gets correlated with what was purchased, and then they sell that data for marketing purposes. Exactly like Google selling your search history, except with likely fewer restrictions in place.

Their website doesn't mention how often they get hacked to give away that data for free - to be clear, that data meaning A PICTURE OF YOUR ACTUAL FUCKING FACE. I don't know what resolution, or even what someone would do with it later, I am focusing here on the fact that the picture taking seems nonconsensual, especially for it to be stored in a database rather than simply used in the moment.

They claim to be GPDR compliant, and while I am not an EUian I think if that claim is accurate, they can't be doing any of those things you mention.

My point is, even if we take them at their word that the facial recognition is benign, it was still a dumb choice.

GPDR only applies in the EU, and this happened in Canada. They may actually be GPDR compliant in europe, but have they stated whether they are following those laws where they aren't legally required to?

Most companies who sell worldwide won't bother developing one set of firmware which is GPDR compliant for the EU, and another set for the rest of the world, unless there was an explicit business reason to do so. So when they replied about this incident in Canada with their GPDR status, I thought it was implied that they had only one codebase which was GPDR compliant, and they ship it in Canada, not because they have to but because it's all they have.

Of note, it'd be pretty easy to push an OTA software update to have it go from recognizing a face to recognizing your face

They need to recognize a face because they explicitly state in their FAQ they are estimating purchasers’ age and sex. This isn’t just adjusting lighting. I would not be so quick to say there is nothing problematic here. I’m highly skeptical.

Based on the quotes from the vending company, at first I thought this was just a dumb way to detect when a human is standing there. But it’s worse than that.

So first we get this from a company representative:

The technology acts as a motion sensor that detects faces, so the machine knows when to activate the purchasing interface

Ok, fine. Overkill, but fine. But then their company’s FAQ tells us this:

only the final data, namely presence of a person, estimated age and estimated gender, is collected without any association with an individual.

So they ARE collecting data, and they are trying to obfuscate that fact by saying they are just “activating the purchasing interface”. This isn’t just turning on a lighted display when a person is standing there. “Activating the purchasing interface” means activating the algorithms to analyze my appearance. They are trying to figure out who is buying their product. That’s different.

So they are being shady about their true intentions. They aren’t being up front, and they expect us to trust that they aren’t storing or transmitting anything other than estimated age and sex. Hmm, maybe. But their actions don’t build trust.

Plus, now I have to worry about VENDING MACHINES getting hacked and being used as surveillance devices now too?? Can I just buy a candy bar without being reminded we live in a dystopia?

To be fair that is perfectly valid and benign data to collect to determine what demographics use your service.

I'm sure this is going to be controversial on here though but when you build a service or a device it's usually pretty valuable to know who uses it in order to determine what features to work on next or how to change it.

Of course the ability for them to abuse it is quite high and it would be difficult to trust them not to transmit more information than they're supposed to

I think a big question here is whether or not this feature of the machine was disclosed to the university when they were installed. It's one thing for the university to place its own security cameras that it has control over, but if a third party is placing surveillance devices on the property they should be giving very clear written notice.

You don’t need to add features to a vending machine though, it just needs to take currency in exchange for snacks and drinks. Any metrics of what sells better/worse can be done by watching inventory like we’ve done all of commercial history. They’re over complicating this for no valid reason

There is a valid reason. It's easier. You don't need to get a person to watch/count/analyse the inventory.

The machine can also just count what it sells. It doesn't need to do facial recognition to see who's buying it

Yeah I think you're just paranoid. Maybe you need to understand how this works better before making a snap judgement. No personally identifying pictures are stored. What's wrong with a bit of market research? Knowing which (estimated) gender buys what is not that big a deal.

Y'all can downvote me and argue till the cows come home, but y'all are just paranoid. I see nothing wrong with this.

It's not just what sells, but who buys what. "Demographic X buys this one product more than others so how can we advertise this product to them where they will see it?" Growth is their "valid" reason, you know, like malignant cancer cells.

Ofc it could have been benign, but there is no evidence that it was, while conversely everything that we currently know points to a breach of ethics.

One, they did not fully disclose that a camera was even there (unless I am mixing up this story with another one just like it?). That also makes it impossible to...

Two, they did not obtain proper (or any) consent. A banking ATM that needs to use your face to verify your identity could be an example of a benign use, and ignoring the enormous potential security implications of that atm, it could do so with a popup on the screen "Do you consent to having your face observed?", "Do you consent to storage of your facial data in our database?", "Do you consent to us selling the marketing data we collect from analysis of your facial data?". They did none of this.

Three, when asked about it, they lied. Technically they obfuscated the truth, which is just another way of stating that they lied.

Ofc it COULD have been benign, but so far they are zero out of three already towards that end - and that is even from just what we know so far.

A simple motion sensor would have sufficed. A classic example of someone getting excited about a Tech buzzword and cramming it into a product.

Data like facial recognition can be sold, assuming it was storing and/or sending it somewhere.

Motion sensor is all well and good until they start to implement gait recognition and sell that data as well.

It'll soon know you by your sick dance moves.

Lesson learned: don't name your surveillance tool EvilFaceRecognition.exe

We got a phishing campaign at work awhile back with an attachment named "OktaAccountStealer.pdf"

... I was impressed. What I really want to know is how many people opened it anyway.

They do shit like that on purpose. Someone who is aware enough to read the names of attachments probably won't fall for the rest of their scam. Its a filter to make sure they don't waste their effort on anyone other than the most gullible.

I'm surprised nobody has discussed the most obvious "marketing" use of this data: Differential pricing.

Someone walks up to the machine. Based on the image seen by the machine, they determine which product is most likely to sell, and bump that product's price up by a quarter or 50 cents.

If they're not doing it now, they're preparing to do it in the near future.

That's my assumption as well. Man in a suit checks out the machine? Bump it up. Couple checks out? Bump it up.

It’s funny how much I love cyberpunk fiction but how much I hate cyberpunk reality. Now if the vending machine becomes sentient? Then we are good, until then I guess fuck these guys?

I'll gladly welcome the sentient machines if they can make me a sandwich now and then

I wasn't against the idea of using facial recognition (age/gender) to do things like recommend products, where I first saw it in Japan on train station vending machines.

The difference is that in my example the camera was in a very obvious spot, here it seems it is covertly collecting facial recognition data, and users weren't aware it was happening until a student noticed this error.

This is the best summary I could come up with:


A university in Canada is expected to remove a series of vending machines from campus after a student discovered a sign they used facial recognition technology.

"The technology acts as a motion sensor that detects faces, so the machine knows when to activate the purchasing interface — never taking or storing images of customers."

"The software conducts local processing of digital image maps derived from the USB optical sensor in real-time, without storing such data on permanent memory mediums or transmitting it over the Internet to the Cloud."

Representatives for the University of Waterloo, Invenda Group, Adaria Vending Services, and Mars did not respond to Business Insider's request for comment sent over the weekend ahead of publication.

Facial recognition technology on college campuses is an ongoing tension point for students and staff members, with examples popping up globally.

Tensions heightened in March 2020 when students at dozens of US universities protested facial recognition on college campuses, The Guardian reported.

A solution in search of a problem. They didn't need that tech for a payment interface.

Honestly, what's the big deal? Your face is not secret and anyone who feels like it can photograph you while you're out in public. Vending machines already know who you are if you use a credit card.

However, this is a good reminder to programmers: customers might sometimes see your error messages even if you didn't intend them to. Don't write anything Marketing wouldn't like.

The part that miffs me is that the fact that no one was aware the vending machine was using facial recognition until a student found the error. It would be okay to me if it wasn't being covert about it.
