<1> FaceStation 2 and FaceLite

FaceStation 2 and FaceLite are having the same algorithmic schemes that use the same template.

This algorithm has FA probability of 1/5,000,000(Most secure). 

(Normal : 1/500,000 Secure : 1/1,000,000)

This means that once the total match count is 5,000,000 times, it will happen once.


So how many FA can happen in real life?

Let's take an example in real numbers assuming your security level is set to 'Most secure'. 


- User: 100 (Face Registered 1 per person)

- Number of authentications per day: Assuming 50 people authenticate twice a day. 

The total number of matching times per day is as follows.

Total matching count = number of face * number of authentication

100 * 50 * 2 = 10,000


Total matching count 10,000 a day can be 5,000,000 in 500 days.

Thus, FA can occur once every 500 days. 

This means that FA can occur every day if you installed Facestation2 for AC use on the door and every user(100 people) uses the door 500 times a day.


<2> FaceStation F2

FaceStation F2 is a fusion multimodal terminal with unmatched face recognition performance.

Experience the exceptional authentication accuracy and anti-spoofing performance achieved by Suprema’s unique Fusion technology.


This algorithm has FA probability of 1/10,000,000,000 (Most secure). 

(Normal : 1/100,000,000  Secure : 1/1,000,000,000)

This means that once the total match count is 10,000,000,000 times, it will happen once.


So how many FA can happen in real life?

Let's take an example in real numbers assuming your security level is set to 'Most secure'. 


- User: 1,000 (Face Registered 1 per person)

- Number of authentications per day: Assuming 500 people authenticate twice a day. 

The total number of matching times per day is as follows.

Total matching count = number of face * number of authentication

1.000 * 500 * 2 = 1,000,000


The total matching count 1,000,000 a day can be 10,000,000,000 in 10,000 days.


Thus, FA can occur once every 10,000 days. 


This means that FA can occur every day if you installed Facestation2 for AC use on the door and every user(1,000 people) uses the door 10,000 times a day.


Please be aware that the above result does not apply to user face authentication with wearing a mask.
