For us who use cell phones on a daily basis, whether for work, studies or simply as a hobby, it is important to keep all our information protected in a secure manner.
As we know Apple devices have years using the method unlock Touch ID on their devices using the Home button, but since the launch of the iPhone X Apple decided to remove the Home button and add a release system using facial recognition Face ID.
While the vast majority of Apple consumers didn’t think it was the best idea in the world to have removed the Home button and added Face ID, others did find it cool and innovative. Even because they can add and configure Face ID for two different people.
When it comes to unlocking your cell phone with Touch ID, it doesn’t matter if you are wearing gloves or have wet fingers, it will still unlock. Likewise, Face ID will recognize your face whether you wear glasses (either sun or reading) or are wearing a mask, it will still recognize your face.
Differences between Touch ID and Face ID
So is Touch ID or Face ID better? Next we will see what are the differences of these two unlocking methods and which is faster.
Touch ID
Apple introduced Touch ID in 2013 at the launch of the iPhone 5s, from there the other mobile devices that Apple has been announcing over the years have this unlocking method integrated.
The Home button is lined with sapphire crystal, which allows the fingerprint to be detected. This sensor uses advanced capacitive touch technology in order to obtain a high resolution image of the fingerprint from small sections of subepidermal layers. Touch ID classifies the fingerprint into one of three basic types: arc, loop, or spiral.
Touch ID can read multiple fingerprints , and it is capable of doing so at a 360 degree angle and thus creates a mathematical presentation of the fingerprint and compares it with the data already recorded to identify the match and thus be able to unlock the device.
All fingerprints are unique so it is impossible for two different fingerprints to be close enough for Touch ID to register as a match. You can use Touch ID to buy apps and songs instead of entering your Apple ID account key. The best thing about this unlocking system is that it is super easy to configure.
This locking system does not store photos of your fingerprint, it only uses a mathematical representation, which makes it impossible for someone to redesign the image of your fingerprint from this stored data.
Face ID
Face ID technology was launched by Apple in 2017 at the launch of the iPhone X, where Apple announced that it would no longer have a Home button with a Touch ID unlocking system but would have facial recognition, so it is only available in iPhone X or later.
The TrueDepth camera accurately captures facial data by projecting and analyzing more than 30,000 invisible points that create a depth map of the face from which an infrared image is obtained.
Face ID automatically adapts to changes in appearance, such as makeup or facial hair growth. If there is a very noticeable change in the face, Face ID confirms the identity through the user’s code before updating the face data and it is quite easy to configure .
It is designed to identify your face regardless of whether you wear many accessories on your face. It works indoors and outdoors, even in total darkness, so under any circumstance you will be able to unlock your cell phone.
Touch ID or Face ID?
After many tests they have come to the conclusion that Touch ID is a little faster than Face ID facial recognition. The difference is minimal. It all depends on the comfort and preference of the consumer, since for some it is faster and more comfortable to lift the phone and for others it is better to simply place your finger on the home button.
Touch ID: Fingerprint Recognition
What is Touch ID?
Touch ID is Apple’s fingerprint recognition system that was first introduced with the iPhone 5S. It uses a capacitive Touch ID sensor built into the home button of compatible devices to scan and authenticate fingerprints. This technology allows users to unlock their devices, make purchases, and access secure apps by simply placing their finger on the home button.
How does Touch ID work?
The Touch ID sensor takes a high-resolution image of your fingerprint and analyzes it to create a mathematical representation known as a fingerprint template. This template is encrypted and stored securely in the device’s Secure Enclave, a specialized chip that keeps your biometric information safe. When you place your finger on the Touch ID sensor, it compares the captured fingerprint with the stored template and grants access if there is a match.
Pros of Touch ID
- Speed and convenience: Touch ID is incredibly fast and allows for seamless unlocking of your device with just a touch of your finger.
- Versatility: Since fingerprints are unique to individuals, Touch ID can be used by multiple users on the same device, making it ideal for families or shared devices.
- Security: Fingerprint recognition is considered one of the most secure forms of biometric authentication as it is difficult to fake or replicate.
Cons of Touch ID
- Placement of Touch ID sensor: On newer iPhone models, the Touch ID sensor is located on the back of the device. This can be less convenient and harder to reach compared to the front-facing sensor on older models.
- Limited support: Not all Apple devices support Touch ID. The feature is primarily available on iPhones and iPads, excluding older models.
Face ID: Facial Recognition
What is Face ID?
Face ID is Apple’s facial recognition system introduced with the iPhone X. It relies on the TrueDepth camera system, which consists of an infrared camera, flood illuminator, and dot projector, to accurately capture and analyze your facial features. This technology allows users to unlock their devices, authenticate app purchases, and securely access sensitive information using their face as the key.
How does Face ID work?
When you look at your device, the TrueDepth camera system projects thousands of invisible dots onto your face to create a detailed 3D facial map. The system then compares this facial map with the enrolled facial data stored securely in the device’s Secure Enclave. If there is a match, the device unlocks, granting access to the user.
Pros of Face ID
- Hands-free authentication: Unlike Touch ID, Face ID does not require any physical contact. You can simply look at your device, and it will recognize your face.
- Enhanced security: The sophisticated 3D facial mapping used by Face ID makes it difficult for someone to unlock your device using a photograph or a mask.
- Accessibility: Face ID can adapt to changes in your appearance, such as wearing glasses or growing a beard, ensuring consistent and reliable authentication.
Cons of Face ID
- Face ID obstruction: Face ID may not work as effectively in certain scenarios, such as wearing a face mask or sunglasses that obstruct a significant portion of your face.
- Angle and distance: Face ID works best when the device is held at a comfortable viewing distance and is positioned within a certain angle range. Holding the device too close or at an extreme angle may result in authentication errors.
Conclusion
Both Touch ID and Face ID offer convenient and secure ways to authenticate and unlock your device. While Touch ID relies on fingerprints, Face ID utilizes facial recognition technology. Consider your own preferences and usage patterns when choosing between the two. If you prioritize speed and versatility, Touch ID may be the right choice for you. On the other hand, if hands-free authentication and enhanced security are your priorities, Face ID is worth considering. Regardless of your choice, Apple continues to innovate and improve biometric authentication to make our digital lives safer and more streamlined. Remember to regularly update your device’s software to stay up to date with the latest security enhancements.
