Data is a Toxic Asset
<i>The Ashley Madison data breach was such a disaster for the company because it saved its customers' real names and credit card numbers. It didn't have to do it this way. It could have processed the credit card information, given the user access, and then deleted all identifying information. To be sure, it would have been a different company. It would have had less revenue, because it couldn't charge users a monthly recurring fee.</i><p>This seems to me the wrong way to solve the problem. The crazy thing about credit cards, social security numbers, and bank account numbers is that these numbers are supposed to be kept secret and private, and yet you need to constantly give them out to people. Everyone you write a check to gets your bank account number, every place you buy from gets a credit card number. This is insane.<p>The right way to solve this is that Visa and Master Card need to develop a standard to make super easy to generate a unique payment number everytime you make an online purchase. Then that should be built in as a browser extension or component. So I browse to a site, click to pay with my Visa card, and Visa automatically generates a unique code for that site and fills it in on the form.<p>Also it is insane that someone can steal my identity by simply knowing my social security card. The right way to solve this would be to have an indentity provider that has a short 10 second video of myself on file. Then, when I want to sign up for a credit card or bank account, I take a 10 second video of myself using my cell phone, granting approval to open the account. A staffer at the credit card company then compares the video with the video on file with the identity provider, and verifies that it matches. The identify provider also sends a message to an email address or mobile number on file, so that I am alerted that someone is opening an account in my name. Using these two simple safe guards, identity theft would be much, much harder. A video recording of a person is very hard to fake, much harder to fake than a signature.<p>A final key innovation would be if email providers would make it super-easy to generate aliases per site. I do this myself manually with fastmail, but if there was a simple browser extension that would automatically create an alias and fill in a form, that would be great, because I could have a unique address that all funnels into one place, for everything I sign up to.
