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

虹彩認識:

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

指紋スキャナ認識

Fingerprint recognition 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

正確さ

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.

Iris recognition:

正確さ：

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

正確さ：

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

スピード 

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

安全

• 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

料金

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

Iris recognition:

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.

Fingerprint recognition:

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.

標準

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.

Iris recognition:

1: ISO/IEC 19794-6:2011: The standard format of iris image data format specifies how to encode and store iris images.
2.ISO/IEC 30107: Provides a framework for iris recognition, liveness detection
3.ISO/IEC 29794-5: Makes technical requirements for iris recognition systems, performance indicators, test procedures, etc.
4.NIST Biometric Image Software (NBIS): Developed by the National Institute of Standards and Technology, it provides tools for processing biometric images

Fingerprint recognition:

1.ISO/IEC 19794-2:2005: Standard format for fingerprint image data format, which specifies how to encode and store fingerprint images
2.ANSI/NIST-ITL 1-2011: Specifies the specifications for the exchange of fingerprint, facial and other biometric data
3.ISO/IEC 30107 Methods for evaluating liveness detection capabilities
4 FIPS 201: Requirements for US federal identity credentials

Pros and Cons

Iris recognition:

Pros:

• Fast speed:
• High accuracy:

Cons:

• High cost

Fingerprint recognition

Pros:

• Low cost:
• Widely used

Cons:

Influence of external environment

Use Cases

Both devices can be used for biometric authentication. Iris is generally used in places with high security requirements and dark environments; fingerprints are suitable for places with low requirements and daily use
