Face Recognition Advantages And Disadvantages

Introduction

Humans perform face recognition with minimum effort on a daily basis, and this form of biometric has many advantages over fingerprint and iris recognition, one of which is that face recognition can be performed in a covert manner from distance. Face recognition systems can be easy to integrate into most environments as these systems can collect a large amount of biometric data in a cost effective manner. Face recognition can also cause less inconvenience to the user than other biometric methods as the system does not require a user to contact the recognition device with any part of their body which can make it easier when collecting biometric information [1].

Face detection and recognition can be a challenging problem for developers

This password can then be used to access the computer if there is a false rejection from the facial recognition software.

The final steps of the configuration process allows the user to select the webcam application that they will use in conjunction with the KeyLemon software in order to access their computer. KeyLemon software can then be configured to stop using the webcam after a specific time limit chosen by the user, which should be implemented to avoid unnecessary power consumption by the machine.

FIGURE 4 FINAL CONFIGURATION

Shown in Figure 5 are the settings that can be configured to add extra security to the KeyLemon product. These settings are not available when using the free version, so settings to improve the security like enabling eye blink detection and increasing the security level were not available for the evaluation of this

Figure 6 shows a test carried out by myself on the KeyLemon software in order to perform a security assessment of the product. Using a mobile device I took a front facing photograph of myself which was similar to the image that KeyLemon had stored of me for authentication to my computer. Once I had opened the login screen of my computer I then proceeded to hold the mobile device which displayed the photograph I had just taken in front of the webcam. Immediately the face detection box turned green which indicated that it did recognise the face being displayed in front of the webcam. The KeyLemon software didn’t allow access to the system immediately, but after approximately one minute of holding the mobile device containing my image in front of the camera the software then validated the image as being me and allowed me access to my
