Ever since reading about the rumors of face authentication potentialy popping up in the next iPhone release, I've been very excited about it. I'm not getting my hopes up too high, as everything is simply speculation at this point until we see the presentation. However, thinking about different implementations of the technology is interesting. I know a lot of people are worried about losing Touch ID, but honestly, I'm all for it if face authentication is implemented well. I've been brainstorming on different ways the technology could be used in the iPhone. I'm going to refer to it as Face ID for the remainder of the post. Imagine if... Face ID could authenticate your face before you go to use Apple Pay and then provide you with a small window of time to hold your phone near the terminal to complete the transaction. This would be similar to how Samsung Pay works in that you don't have to keep your finger on the fingerprint scanner during the entirety of the transaction. You authenticate and then hold the phone near the terminal. In this regard, people wouldn't have to be worried about the awkwardness of keeping their face in front of the phone while holding the phone next to the terminal. Imagine if... Face ID could automatically lock your phone if someone took it from you. The cameras could quickly detect and scan the face in order to lock the phone upon realizing it's not your face. Obviously, there would need to be measures in place to prevent this action if you voluntarily gave your phone to someone. This would be a nice security feature nonetheless. Imagine if... Face ID could be used to scan your facial expressions (i.e. smiling, frowning, angry) to insert emojis into your text similar to how Siri dictation works with texting. This is probably a little bit more of a stretch in regards to implementing, but it could be fun for those that enjoy emojis especially considering the time Apple has invested with emojis and iMessages. Imagine if… Face ID could be used in an App Store game where it scans a user's face to attempt to detect the user's age. I know this is pretty trivial in the grand scheme of things, but I'm sure there are those who would download it to try for fun. There are surely many ideas where it could be used with games. Imagine if… Face ID could scan a user's face and automatically locate all pictures in the Photos app that contain that person's face. Apple already uses face detecting algorithms to group people based on their face. It wouldn't be a far stretch to see these two work in conjunction to perhaps find a specific picture of someone or create an album of them. Imagine if… Face ID could be used to scan a user's face in order to detect a smile that could be used to coexist with the action of pressing the shutter button for the Camera app. For a front or rear facing picture, simply smile, Face ID defects the smile, initiates camera focusing, and snaps a picture. These are just a few ideas I've come up with. I'd love to hear input from others. Ideas, concerns, criticisms, or anything else to do with the technology or the potential loss of Touch ID are welcome.
