Not long ago Apple released an iPhone that introduced Touch ID, the fingerprint scanning technology that helped to secure more phones around the world than any previous tech ever had. The only way to unlock devices protected with Touch ID was with an authorized fingerprint, rather than a multi-digit PIN that could easily be stolen by anyone looking over your shoulder.
But despite their superiority over number locks, fingerprint identification systems have their flaws. The greatest of which is that a copy of the pass word is left on virtually every single surface that you touch throughout the day. Granted, these prints are much harder to steal that a PIN, but not impossible. And for devices and systems that need the highest levels of security available, Touch ID may not be enough.
Another flaw with fingerprint ID systems is that few users prepare their devices to accept all ten of their prints. For convenience purposes, many people only scan one or two of their fingers that are most commonly used to unlock the device, and skip the remaining digits.
Then, after even a minor injury, a finger bandage might as well be a brick wall, keeping even
authorized users from unlocking their phones. Admittedly, these scenarios are rare, but that’s exactly why so few people think to scan all of their prints in the first place.
All of this is to say that there is room for improvements on the current level of iPhone security, which is why Apple is working to develop eye scanning capabilities for its next model. Much like fingerprints, each and every human eye is completely unique. They are also more secure, since they are nearly impossible to duplicate.
This is partly due to the fact that the eyes don’t leave a mirror copy of themselves on everything we look at (unlike our fingers), but mostly because of the detail and complexity of the eye itself. Fingerprints are identified by measuring individual characteristics, such as loops, swirls, and rings. These features provide approximately 40 points of data for a fingerprint scanner to work with in order to identify the user. Eyes, however, have more than 250 unique points of reference, including the color patterns of the iris, as well as the patterns of blood vessels that stretch across the retina like a “tangles” spider web.
As of now, these purported new iPhone features are only a rumor that are circulating around the tech industry, but they come from sources with historically hit-or- miss track records. Should these rumors turn out to be true, you can expect to see eye scanning capabilities in an iPhone as early as 2018.
