Unlocking a portable electronic device by performing multiple actions on an unlock interface
First Claim
1. A method of unlocking an electronic device, the device including a touch-sensitive display, the method comprising:
- displaying an unlock interface;
detecting a contact with a first unlock interface element;
loading a first access credential based on the detected contact with the first unlock interface element;
calculating a first magnification percentage based on an extent of the difference between the first access credential and a first stored unlock credential;
reducing the number of remaining unlock attempts available to a user based on the first magnification percentage or leaving the number of unlock attempts available to a user unchanged; and
detecting a contact with a second unlock interface element;
loading a second access credential based on the detected contact with the second unlock interface element;
calculating a second magnification percentage based on an extent of the difference between the second access credential and a second stored unlock credential;
calculating an aggregate magnification percentage based on the first magnification percentage and second magnification percentage; and
reducing the number of remaining unlock attempts available to a user based on the aggregate magnification percentage or leaving the number of unlock attempts available to a user unchanged.

Abstract
The disclosure provided herein includes a multi-step authentication process to unlock a portable electronic device. To unlock the device, a user can use a touch screen on the device to select an access category, to select an access subcategory, and to enter an access subcategory value. The access subcategory can depend on the access category, making them logically related. The access subcategory value can be a value that corresponds to the selected access category and subcategory. The multi-step authentication or unlocking process can advantageously be easy to remember because the pieces of information to be provided are logically related to one another. In addition, the multi-step authentication or unlocking process can be difficult to guess as each step in the process decreases the chances an unwanted person or system correctly guesses the correct values for each step.
