If you were a fan of Lockdown Pro, the tweak that added password/passcode protection for select apps on your jailbroken iPhone, you’ll love this. Elias Limneos, developer of tweaks like SBRotator, CallBar, has posted a teaser of a new tweak in development that uses the iPhone 5s’ Touch ID sensor to authenticate a user before an app is opened.
Apple currently restricts the use of Touch ID only for unlocking the device and authenticating iTunes purchases. There’s no (public) way for third-party developers to use the Touch ID for authentication in their own apps.
In the minute-long teaser video, Limneos demoes opening certain apps on the iPhone 5s, which then pops an alert asking the user to “give me the finger.” If the authentication is a success, the app is opened, else the alert pops up again.
Apple says that the Touch ID stores a mathematical representation of your fingerprint in an encrypted fashion in the A7 chip’s Secure Enclave. While it is normal to be concerned about this tweak from a security standpoint, we’re guessing it uses a high-level, albeit private, framework to access Touch ID functionality, that doesn’t have access to the actual fingerprint data.
Let us know what you think about this upcoming tweak in the comments below.
