4:20 PM -- I've been following security on the Web for a long time, and I've reached the point where most the new stuff doesn't freak me out. Heck, a lot of it is just plain annoying.

But there's a new Web service out there, Polar Rose, and it both interests me and freaks me out. In fact, my initial reaction is that maybe there ought to be a law against it.

On the one hand, it's nothing fancy. It's facial recognition. But then again, it's better than average facial recognition -- and it's been turned loose on all the pictures on the Web. In its launch announcement, Polar Rose promises that the new service will allow users to:

There are a bunch of other capabilities, too, but I'm particularly concerned about points two and four.

Not to sound paranoid, but here's a handy way to unite all your enemies on the Web. You're at a wedding, say, and pictures are made. There you are, seated at the table with friends of the groom, and it's been posted on Mark and Melissa's "Now We're Together" blog site. With Polar Rose, people who want to monitor you will now get a heads up.

Now, I don't care if anyone knows that I was at Mark and Melissa's wedding. But it's the start of a portfolio of information about me and my friends that's automatically updated. You don't really need a paranoid like me to spin a few scarier scenarios here, do you?

Here's a weird twist. There's a new feature on Google Maps called Street View. It's only available in a few cities, but it's a concept I've always thought somebody should realize -- the ability to move through a series of sewn-together photos of the actual streets. It's great stuff if you're headed somewhere unfamiliar, and you want to know what a tricky intersection actually looks like.

Right now, the pictures in Street View are pretty blurry -- just enough detail to give you an idea what stuff looks like. But the pictures are made on normal days, presumably from a car as it drives along, and there are plenty of real people in these pictures, most of them unaware that they're being photographed.

I'm sure the blurriness is intentional (and a good thing, I'd say). But imagine a less blurry version of this, coupled with Polar Rose. See that girl walking along Fifth Avenue there? Well, just maybe Polar Rose gives me her name and shows me 15 other photos -- photos that show her to be a regular at a dance club downtown, and tends to be there Thursday nights.

Just maybe, Polar Rose becomes the stalker tool from hell.

Polar Rose, which isn't actually in public beta yet, has enough sense to know there are some privacy issues to worry about here. From the company's blog:

Polar Rose doesn't say, mind you, that it will let you opt out from being identified in pictures that appear on other people's Websites. It just just says it won't pick up photos in certain circumstances (such as if you've put them off limits to Web crawlers using robots.txt).

I suspect some creepy stuff to come out of this.

— Robert Richardson only has a couple pictures on the Web -- one of them makes him look so green-skinned that he's worried Polar Rose will mistake him for Kermit the Frog (find it yourself, thank you). In other photos he appears as the director of the Computer Security Institute (CSI) . Special to Dark Reading.
