Last Saturday, 450 or so developers trapped in a San Francisco convention center spent 24 hours competing to create the best new software/hardware idea using publicly-available data and APIs. It was for a contest. A hacking contest.

I bring it up because the winning design, WiseDame, is pretty ingenious—especially if you, like me, are a lady obsessed with true crime shows like I Survived, Captured, Snapped, and other programming that profiles violent acts against women (and, in the case of Snapped, shows them, um, snapping).

Anyway: WiseDame is designed for women. It's a "little black box" application for the iPhone that "provides information about what you were last doing before an emergency occurs," says developer J’aime Ohm. "It encourages women to be into their security." You could potentially grant people access to your phone's information, and your phone could passively collect data and then release it, black box style, in the case of a real emergency, like when you've been abducted and are trapped in someone's closet/trunk/wall/hole in the backyard. (Gruesome, I know, but also efficient.)

Ohm calls her design "effortless security." Obviously, it's not yet consumer-ready, but it's still an exciting development—as exciting as the day Taser announced its lady line of stun guns.
