You're probably thinking, "No it doesn't! That's ridiculous!"
It is ridiculous, but it might come true soon.
I was going through some news articles when I came across an article in the EFF linking to this gem of a patent filing. Apple, in a move to counter the government's new rules permitting the jailbreaking of phones for non-copyright infringing purposes (among other things), still wants essentially total control over the products they sell to consumers. This patent basically details all of the ways that they plan to catch unauthorized users from using the product and unauthorized software (e.g. copied music) from getting onto the product. It includes ways of identifying unauthorized users or usage such as proximity sensors, voice recognition, facial recognition, and heartbeat recognition. WHAT?
I can use other people as cover for the proximity sensors. I can change my voice/tone to fool the voice recognition. I can even wear masks to avoid facial recognition. But how am I supposed to mess with my heartbeat? The worst part in that is that Apple isn't using the heartbeat sensor to detect changes in a person's heartbeat (that could quickly turn for the worse); it's using those sensors solely to prevent people from using Apple products in ways that Apple doesn't like.
People, please vote with your wallets and stay away from Apple products! Apple seems to have no reservations about turning such data over to the US government, and with the US government (initiated by the MPAA, RIAA, and other such organizations and companies) looking to implement even more draconian restrictions on users' technology and files, the consumer is being demonized here. If people continue to buy Apple products, Apple will then have enough money to make new iPhones and iPods that are able to detect users' heartbeats (among other things); if you also think that this is ridiculous and somewhat creepy, stay away from Apple!
