MasterCard Transactions To Be Mined For CO2 Data 124

seamus1abshere writes "In the latest twist from Big Data, MasterCard and Brighter Planet today announced that cardholder transaction data will be mined for clues about CO2 emissions. Initial coverage will be of flights, car rentals, hotels and other purchases for which the credit card company stores extra metadata. Interestingly, the science behind the offering is all open source."

        As some one that processes credit card transactions on a daily basis, I know for a fact that all you need to run a credit card at a terminal is the 16 digit number, 15 if it's american express, and the four digit expiration date. The terminal never asks for the card holder's name and only rarely askes for the three digit security code on the back of the card. All they need to complete their pointless and meaningless study is a transaction date and number, and maybe the transaction amount. There is absolutel

    • Mastercard has been giving aggregate data back to its member banks for at least 20 years. This is just another set of aggregate data, but given to corporate card holders. Even if they gave card numbers, names, and addresses, it's only going back to the owners of the cards.

      I worked with Mastercard's data warehouse for 5 years. So if anyone has any questions about what *really* goes on there I might be able to answer (although I can only speculate about this particular program).

          The short answer is that data is somewhat compartmentalized by department. Each CC transaction first comes through the mainframes, which are very restricted, mostly just for IT. That data is fed nightly to the data warehouse (basically one massive database). A lot of IT get direct access as needed. Some business / reporting applications are then written to query directly from it, limited to the departments that would require it. Any department which needs aggregate data has separate database servers, with data warehouse IT staff facilitating the automatic feed and aggregation of the data.

          Requests for data from outside the company are taken case-by-case. So, for example, when I had to write reports for a particular bank (a Mastercard member), I was careful to only pull that bank's data. I didn't filter anything that was specific to their cardholders. For applications which got aggregate data, individual transactions and CC-specific data was never sent to the application's database servers. It was carefully aggregated first at the warehouse, then transmitted. I have to say there wasn't much general oversight, but it's simply enforced by management throughout the company.

        When you are logged in or have auto-login enabled for Yahoo it is more likely some smart XSS exploit that loads Yahoo in a hidden IFRAME and posts the address book to their servers by means of the XSS payload. Typically this works with all mayor browsers and does not require your address book to be stored locally or your memory to be read directly.
        • In this case it would be a CSRF [wikipedia.org] attack.

            A CSRF can perform an unwanted action, but to post content back to the attacker another method needs to be used (the attacker might request the contact list in the IFRAME but will have a hard time to read it since modern browsers prohibit this). When the attacker has the ability to execute arbitrary JavaScript by means of a XSS exploit this becomes much easier, so this would basically be a CSRF with a XSS to get the result from the request forgery.

    I imagine that the most important piece of information regarding the transaction is the supplier and a transaction number. The amount is worthless. How would you match an amount to a product, especially if more than one product is purchased? Many customers pay different amounts for the same product, how will they factor this in? They'd have to ask the supplier what was actually purchased with some kind of order number.

    Some services are bought but not redeemed later in the future such as a flight or a cruise ship. They need to work out when a servie is actually utilised.

    Somehow I think they'd be better of analysing public transport systems. Such as buses, trains, planes and traffic. If 10 people buy a bus ticket, the bus will expel the same amount of CO2 than if the bus was full. Same with trains, they are quite often under capacity.

        I find the psychology interesting here. Companies have tracked spending on corporate credit cards since forever; after all, it's their money you're spending, not yours, and they don't want you to spend it on booze and hookers. I don't remember ever hearing anyone complain about the principle of this. But as soon as Mastercard start to offer carbon emissions analysis to their corporate customers -- because 80% of those customers wanted it -- we have a dozen outraged comments about "invasion of privacy" and "the cult of global warming".

        No the parent is not trolling. "How much energy will be spent tracking this" is a perfectly valid question. If I spend x+10 energy on monitoring to save x+1 energy then that's a problem.

A giant power plant generally operates at much higher efficiencies (generally ~2x the efficiency of a typical car motor, if I recall correctly) than your automobile engine - less fuel is consumed to produce the same amount of energy, which means less pollution is emitted.

      Good point. The problem is that we're talking about global warming.

      • One time events (like weather measurements) are not independently testable by definition. You can still do fact finding without a full scientific process. It just needs a different review process. Peer reviewed fact finding only works if you have reproducible results. One-time events have to reviewed through an adversarial review rather than peer review.
