Animal Biometric Door

The Flo Control Project, named after the feline Flo, has posted a promising update on their animal access control door. They added a facial-recognition system to try and deny Flo access if she has something in her mouth. Technically they are basing recognition on a shadow profile, rather than on Flo’s actual face.

The database of images for access success and failure is probably the best part of the entire story. The key weakness (pun not intended) of physical access systems is usually related to monitoring. A building with only ten doors and half that many cameras can easily find an operations center overwhelmed or soon uninterested in the data. One way to avoid this is to create an analysis and alarm system. Another is just to run tests that are interesting or even amusing. Flo gives a perfect example of the latter:

Flo was allowed in in all of these instances, appropriately so. The vast majority of captured images are like these, just Flo by herself. She goes in and out 5-10 times a day, so we get a lot of these. Cases when the latch does not open are much more rare, especially now, when there are not many animals for Flo to catch. Still, she tries to bring something in occasionally, and we also get other unauthorized visitors: skunks and even birds. Below are some of the cases when the latch did not open.

This brings to mind the story of Little Red Riding Hood. It certainly has shades of “what a big nose you have!”

It also brings to mind the purpose of a cat bringing its catch home. Perhaps a better setup would be a cat-trap (e.g. man-trap for cats) where Flo could deposit her catch to secure it and receive praise. A similar model could be a DCZ (De-Catch-ified Zone) that would exist as a segment between outside and inside.

Personally, I have been thinking about another control I would add to an animal control system, which I’ve mentioned before on this blog. Perhaps if I have time I’ll give it a go and test it on my own animal(s). Right now, however, my pet(s) are not violating any policies and I do not have unauthorized animal access issues.

Starbucks’ Security Policy

The Associated Press ran a story called Buzz and bullets: Gun fans cheer Starbucks’ policy that gives a good indication of a hot topic in the US:

Dale Welch recently walked into a Starbucks in Virginia, handgun strapped to his waist, and ordered a banana Frappuccino with a cinnamon bun.

Sounds like the start of a bad joke, right?

They make a banana flavored “Frappuccino” now? People drink this? A cinnamon bun on the same order and a case can easily be made that some Americans have lost their senses.

Perhaps he needed the gun to help convince the staff to put the two items on the same order. “Give me as much corn-sweetener as possible, to go, now!”

You think that is funny? There is more, like this sentence:

…about 100 activists bearing arms had planned to go to a California Pizza Kitchen in Walnut Creek, Calif., but after it became clear they weren’t welcome they went to another restaurant.

Walnut Creek? A wealthy white suburban conservative neighborhood was the target of a pro-gun rally? Hardly risky territory for a pro-gun groups, but even with stats in their favor they backed down. Why? Perhaps they realized they didn’t like pizza anyway.

This reminds me of how basic rights are lost on private property. You lose your First Amendment freedom of expression if you step into a Starbucks. Do gun activists feel they should get special treatment for a later Amendment? Start with the first. I have seen some say they believe this is about individual rights, but I doubt they really want to share a stage at Starbucks with speech activists.

Moreover, a security perspective sets aside individual rights and brings it all back to a question of how to manage risk. When those allowed to carry guns are clearly known to have a service role (federal, state, etc.) you have a very different situation. A police officer with a weapon has a uniform, a badge with a number, etc. to make them easily identified as someone trained and trusted with a weapon. This is common around the world because service personnel are essentially trusted. The idea of a random individual carrying a gun onto private property (the individual rights argument) opens a whole different can of worms related to authentication and authorization. How do you, as a customer, let alone a shop owner, make a risk judgment in a world of individuals carrying firearms? In other words if free speech already has been deemed too risky and not allowed on private property for random individuals, one would presume carrying a firearm would be treated the same or even more caution.

Seriously, though, when you think about chain pizza, syrupy coffee and cinnamon rolls this is hardly a story about fundamental rights or even security. Those are just a cover. It tastes more like a marketing campaign with some free press to promote expensive designer fashion food to a group most likely to pay for it — customer relationship management.

Cheese Fraud

An article by the Times Online explains a recent crackdown by authorities on cheese fraud in Italy:

[Luca Zaia, the Agriculture Minister] said there was no health risk, adding “It is not a question of food security so much as of respect for the rules of production”. However he had taken “urgent action” by placing the mozzarella consortium under “special administration” for three months while a committee of police and ministry inspectors investigated.

He said he had acted “because the situation was deteriorating. Over the past two years my zero-tolerance policy has led to the discovery of many causes of food fraud. In November, checks in major supermarkets in Italy found that 25 per cent of the cheese sold as buffalo mozzarella was fake because it contained 30 per cent cow milk.”

Great example of how compliance depends on governance. It is a good thing he has no jurisdiction over the US cheese market or almost the entire mozzarella supply would be abruptly halted. I have tried without much success to find a consistent source buffalo mozzarella in America.

This case is notably different from a security risk that is also mentioned in the article.

Two years ago sales of mozzarella fell after buffalo milk was found to be contaminated with high levels of dioxin from rotting piles of uncollected rubbish in the Naples area. Sixty-six buffalo herds were quarantined and over 100 farmers and dairy producers were investigated for alleged “fraud and food poisoning”. In April last year inspectors found that some buffalo in the Caserta area near Naples had been given somatropine, a human growth hormone, although officials said this did not pose a health risk.

Thus compliance also depends to a large degree on consumer awareness and interests. Governance is meant to be a representation of demand, so risk definition becomes one of the first steps to creating rules for compliance. Risk from dioxins, for example, is much easier to quantify and campaign against than the risk from lack of authenticity. Who is harmed when cheese is fake? Many Americans, in fact, are likely to turn a blind eye to imitation — mozzarella made from cow milk in California or cheddar from cows in Wisconsin. Risks related to the authenticity of cheese may be far less valued than appearance and price — cheap imitations (“generics”) thus build a strong following when no one close to home is hurt by the practice. Only when authenticity issues hurt a domestic source or more immediate health issues appear do calls for governance come forward.

…food for thought the next time you take a bite of mozzarella.

Top Composter

The Urban Eco Map of San Francisco reports that my neighborhood is leading the city in pounds composed and is third overall! A wide margin separates the top two zip codes in composting. Is there an award?

As far as cities go, San Francisco is one of the cleanest and greenest in the US. We have great mass transit. Much of our energy comes from clean, renewable sources. We recycle 72% of our trash. And we are well on our way to reducing overall greenhouse gas emissions to 20% below 1990 levels – ahead of the Kyoto Protocol.

Balboa is in solid last place with huge amounts of CO2, energy used and very little recycling. There is no deeper analysis of the data on the site, just numbers. It would be nice if the Take Action page could be correlated to a neighborhood. Just by selecting all the waste action items I was able to get to 100% on the contribution chart, leaving energy and transportation untouched. That doesn’t seem right and inconsistent with the charts.
