iOS device security has regularly been a concern of the government, but locking down one of Apple's devices for the government is still fresh. Precise Biometrics hopes to have the problem licked through the Tactivo, a combo fingerprint and smart card reader for the iPhone 4 / 4S (and the iPad, in the summer). Either method keeps data inside an app away from prying eyes, and while they won't tighten the security around the built-in apps, they do make sure a third-party app's data meets US and international government privacy specs without having to use a BlackBerry. We're not surprised that the Tactivo needs to engulf the iPhone in a full case to work its magic, although there's a micro-USB port to keep it powered and synced up. It's all a bit much if you're just trying to make sure your list of high school crushes stays a secret, and the price reflects that -- at $249 a pop, the Tactivo is really meant for agencies and companies for whom losing the data on an iPhone would cost a lot more. Still, if you're running an outfit encouraging BYOD phone use or just really, really want your secret passions to stay private, both the iPhone case and a BioSecrets app are ready today.
