Iris Recognition Scanner VS Fingerprint Scanner

Iris recognition and biometrics are both technical means of identity authentication. They have their own characteristics in technology, speed, and function. You will get information about the comparison between the two from the following article.

The  Overview of iris scanner and fingerprint scanner

Иристі тану:

Iris recognition is an emerging biometric technology. It collects characteristic points in the human eye, compiles them into iris images with characteristic points according to the iris algorithm, stores them in the data, and compares the data collected on site with the image in the database to complete the process of personnel information recognition

Саусақ ізін тану is a relatively mature and widely used technology. It collects fingerprint images of human fingertips, processes them according to the fingerprint algorithm, converts them into a unique digital code, saves them in the database, and compares the information stored in the data with the data collected on site.

How do they work

The core work of iris recognition and fingerprint recognition is to collect data and compare the collected data. The specific workflow is as follows

Summary of differences

Дәлдік

Accuracy is affected by many factors, you need to consider them comprehensively, such as the quality of the system, the algorithm, the environment, and the crowd.

Иристі тану:

Дәлдігі:

Under the best conditions, the accuracy of the iris recognition system can exceed 99% (the best here means that all conditions can reach more than 90, the acquisition equipment must be the best, the algorithm must be the best, the environment must be the closest, and the crowd must be the best)

False rejection rate:

The possibility of wrongly authorizing the user, this data is also very low

Distance:

Some advanced iris recognition systems can accurately recognize even at a long distance, but the distance will also determine the accuracy of iris recognition

Fingerprint scanner

Дәлдігі:

The accuracy of the fingerprint recognition system is also quite high, but it is still slightly lower than that of iris recognition, usually reaching between 95% and 99%

False rejection rate:

The FRR of fingerprint recognition is slightly higher than that of iris recognition, generally between 1% and 5%
Accuracy summary

Жылдамдық 

The speed of recognition is also affected by different factors, such as technology, hardware specifications, environmental conditions, algorithms, etc.

Iris scanning recognition

The iris is scanned very quickly, and speed is one of its advantages.

• Capture speed: Mature and advanced equipment can complete the capture of the image within 1 to 3 seconds
• Processing speed: Recognition only takes a fraction of a second to a few seconds

Fingerprint scanning recognition:

• Capture speed: Capture fingerprints in a very short time, usually within 1 second
• Processing speed: In a good system, it can reach 1 second

Қауіпсіздік

• Uniqueness and stability: Iris recognition and fingerprint recognition have their own uniqueness and uniqueness. Iris is generally considered to be more unique and stable than fingerprints
• Vulnerable to forgery: Compared with the two, the fingerprint recognition system is more susceptible to deception
• Live detection: Both support live recognition
• Data protection: Whether it is iris recognition or fingerprint recognition, data needs to be protected. This is because the data is stored on the user’s device

The cost depends on the supplier, interface, and functional requirements;

Иристі тану:

1 Hardware cost: All cameras in the iris recognition system need to capture high-resolution iris images. The cameras used are professional, and the price ranges from hundreds to thousands.
2 Software cost: The cost of iris recognition algorithm is high. It has high accuracy, high speed and liveness detection functions.
3 Total cost: Basic hundreds to thousands.

Саусақ ізін тану:

1 Hardware cost. The hardware cost of fingerprint scanner is relatively low. Generally, it can be done for about 50 US dollars. If you choose a high-function fingerprint scanner, the price will be more than a few hundred.
2 Software cost. At present, the basic algorithms on the market are mature, and the software cost is basically not too high, of course, except for customization.
Total cost: tens to hundreds.
The cost of iris scanning equipment is higher than that of fingerprint scanning equipment.

Стандартты

Iris recognition and fingerprint recognition have their own standards that need to be met. The standards here can ensure the safety of the equipment and the data.
