[Foto : Kompas.com]Apple has registered a patent in the form of the introduction of face detection as a keyword (password). This patent application has been approved by the office of copyrights and patents the United States.
This patent will likely be applied to all Apple devices like the iPhone, iPad, iPod Touch and Mac computers and laptops in the future.
As quoted from SlashGear, presence detection technology can be used to automatically activate or open the Apple device. Especially the face detection technology can replace key words commonly used in all devices.
Interestingly, in addition to the face itself can be used as key words, the device in question can also be configured to recognize faces of family user or the user's friends. So the next of kin could also open the device given in the form of keywords that face detection.
Detection of facial recognition systems from Apple is using matching correlation with computing technology, rather than the traditional correlation of any face shape. In this way, the resources used will be relatively small.
What matters more, this technology can deal directly with the Graphics Processing Unit (GPU) from the IOS device or the Macbook. So as to lessen the burden on the software and rely more on its hardware.
Unlock face feature is actually not the first time Apple's used. Samsung Galaxy Nexus using Android 4.0 has been using this feature first. Samsung actually makes this feature as its main feature.
Based on the function, unlock the registered features of Apple's face and that has been used in the Galaxy Nexus is the same. However, the technology behind it could be different.
Similarly, for its application, Apple uses a 2D system will remember the faces of people who will be the key opening the device. By analyzing the differences between two images, the device can determine the identity of the owner's face. Specification of the patent is more emphasis on skin color, facial shape and features do not require accuracy at the level of illumination. While the Galaxy Nexus, opening the lock can still be opened even if its just a personal photo, not a real face, as reported Mobilepedia in November 2011.
