Are Face Recognition Systems Safe?

In recent years, we have been using passwords, patterns or PINs on our smartphones or laptops until very recently. facial recognition systems We started using it. The widespread use of facial recognition unlocking has resulted in some security concerns brought it with him.

Despite advancing technology, not all facial recognition apps are equally secure. Some may be safer than others, depending on the principle of operation. By examining the face recognition systems that are widely used today, which system safer Let’s decide together.

Camera-based facial recognition system

The camera-based face recognition system, which is the first example of face recognition-based unlocking methods, works by identifying the face on the front camera of the device, as the name suggests. In this technique, you must first take photos from different angles to define your face. The system uses photos to create a software algorithm develops. In cases where the device will be unlocked after the feature is enabled, the live view data from the front camera and the data saved in the system by comparing works. It is mostly used on android devices.

Because the system is based on software algorithms, it does not always give perfect results. Different lighting conditions in the environment, minor changes in appearance or various accessories unsuccessful may cause it.

Infrared based face recognition system

In addition to the front cameras on smartphones, this system to infrared sensors is needed. The method of this system is similar to the camera face recognition system, but the face in the infrared spectrum two-dimensional stands out for taking a picture. This method is different from other it is more advantageous because this system does not need to illuminate the face, it can work even in dim environments. In addition, since these cameras need thermal energy and heat to create the image, it is difficult for a different person to access the phone. is more protected. Usually used in laptop with Microsoft system.

Apple’s Face ID system is also infrared-based. Three dimensional uses a sensor based on image generation. Face ID measures thousands of facial details using an illuminator and dot projector. The infrared sensor examines how these dots are placed, and depth map creates. 3D systems can also work in the dark and are much more difficult to make mistakes. While 2D infrared systems only seek heat, 3D systems also need depth information. For these reasons, it is much more efficient than 2D sensors. is functional.

Which system works more safely?

Electronic storage of biometric data can raise many questions about security. However, it’s nothing serious to worry about. Operating systems incorporating biometric unlocking methods, for the secure storage of sensitive data such as facial features and fingerprints strong measures gets. In smartphones or laptops, biometric data is stored in the device system. a secure hardware It is stored encrypted and isolated in the part.

According to our comparison, it is clear that the infrared-based facial recognition system is safer. Infrared-based systems are also universally considered safer. In addition to unlocking, Apple Face ID and Windows Hello systems can be used to autofill password fields and enable payments. By comparison, depth-sensitive systems (like Face ID) work for most people. is safe enoughwhile camera-based systems changes depending on the person we can say. However, if you still prefer the camera face recognition system, it is better not to use this system to authenticate in Google Play Store or banking applications. Enough if you don’t trust To unlock, you should use alternative encryption methods.
