Online security and Uber

Credit card theft

It seems like credit card data gets stolen all the time. In 2011 Sony made the news with details of over 12000 credit cards being stolen (some reports claimed 2.2 million, I don't know what the final numbers were). Then from March of this year, the Target breach - in which 40 million numbers stolen. There were breaches in between of course, which one could look up if one were so inclined; I'm not taking the trouble since I'm pretty sure everyone reading this knows that it happens, and happens regularly. I just typed "credit card theft" into Google Search and found this story, from yesterdayNearly all US Home Depot stores hit.

How can credit card data be stolen? Here are five ways. Here's a news report on YouTube. Most of us have seen videos like this one before. And when someone steals card data, they can sell it on sites like rescator.cc (not hyperlinked, I'm not sure that going there is a good idea).

So how come this doesn't happen to us sitting in India?

Credit card use in India

In India, having a person's card information is not enough to use it. Even having the physical card itself won't work - because we always have to go through an additional authorisation step.

When we use a physical card in a physical store, we are required to enter a 4-digit PIN number. I remember getting my replacement "chip"-style cards a few months ago, and every merchant I visit has the new machine which reads the chip and asks for my PIN. This method prevents your card from being usable unless the thief also managed to steal your PIN number - and ATM and debit cards work the same way. I don't know what happens if the thief just tries all the numbers from 0000 to 9999, maybe your bank's fraud detection software kicks in.

Online transactions work similarly, when we provide card payment information to a site we are required to authorise the transaction on a different site, showing MasterCard SecureCode or Verified by Visa. This other site is hosted by your bank, and this is important because this way the merchant cannot get your security passcode. Of course it is entirely possible that your bank could get broken into, but it is easier to regulate and monitor a few hundred banks rather than a few hundred thousand online businesses.

Aside: When we transact using Net Banking, we often have passcodes for individual transactions - I know that at least AXIS and Kotak do this - after you initiate the transaction they send a code to your email address or to your phone via SMS, and you have to provide this code to complete the transaction. I wish we had this for card-based transactions as well.

In summary, stealing credit card information in India is basically useless.

Unless...

Well, unless the merchant is outside the country. Our regulators have no sway over outside merchants, and while they could certainly block us from transacting with them, that would be hugely inconvenient for us. So when we transact with foreign merchants, a credit card number and expiration date are enough. And probably the name. No other authentication, no passcodes to be entered on a trusted site, nothing.

Naturally this is not great. It is the online equivalent of walking through a shady part of town - sometimes you have to go, but you don't want to be doing it regularly. I used to buy music on cdbaby, now I don't even do that. What I've heard is that if you are an American consumer, your loss is capped at 50,000 USD. I don't know if that is true, but I do know that if you are Indian consumer you would just be S.C.R.E.W.E.D.

Hello, Uber

Uber is a fantastic service. I followed the news about how they were scaring taxi unions around the world, and getting banned one city at a time, and I remember thinking "Go Girl"(I don't know why I made Uber a girl). I thought the tax unions' safety claims were horseshit, and while I knew that they had to do what they had to do to protect themselves, I also felt that they should be crushed mercilessly (which I don't think has happened yet? I can wait). I also generally believe that the State should regulate lightly and let businesses thrive, especially when large numbers of consumers could benefit.

So Uber came to India (yay!), and I guess they didn't want to subject their users to the extra step of credit card authorisation. Because when people reach their destination they don't want to type things into their phone. Because it's inconvenient.

Yes, it is inconvenient. Just like locking and unlocking your car is inconvenient. Or the door to your house. Or having to show ID when you access your locker in the bank.

We deal with, and even welcome these inconveniences because they protect us. This is about security, and not some abstract "national security", but concrete, personal, financial security. Every one of us should want that level of security.

Well, Uber decided that rather than subjecting their users to standard financial security practices, they were going to bypass them, by... routing the payment through a non-Indian processor. Genius! What an idea. Someone got a bonus for that one.

WHAT WERE THEY THINKING

When I first read that this is what they did, I didn't know whether to laugh or to cry. But that's not all - then I read, and heard, many smart people saying that this was a good thing because it saved time and therefore contributed to GDP growth. And when the regulators told them to stop, that this was regulatory paternalism.

This is not paternalism. This is not cultural policing, this is not the Big Bad Government trying to be your father and telling you what is right and what is wrong. And the GDP of the country is not going to be touched by the time saved when people get out of their taxis. This is not of that, and dressing up a crappy argument with big words and numbers is like putting lipstick on a soowar.

The better approach

As responsible consumers, we want our financial transactions to be protected. But as lazy consumers, we still want the convenience of speed. Technology exists so that we can have it both ways - we shouldn't have to choose.

Rather than trying to be so smart and jugaad-ing the loopholes, Uber should have worked on a real solution. E-commerce is big in India, and I'm sure the large online retailers also want to save their customers the hassle of entering credit card information into their sites and apps every single time they buy something. A process needs to be invented, with the involvement of businesses, regulators and security experts.

California is not going to do this for us - it's our use-case, and we need to solve it.
