Which of the following biometric authentication means is accurate but expensive?Group of answer choicesIrisFingerprintFaceVoice

Analysis of Biometric Authentication Means

1. Iris Recognition: This method is known for its high accuracy due to the unique patterns in the iris of each eye. However, iris scanners can be quite costly due to the technology involved and the need for specialized equipment.

2. Fingerprint Recognition: Fingerprint scanning is generally less expensive and can be implemented with a variety of cost-effective devices. While it is accurate, it often does not reach the precision level of iris recognition.

3. Facial Recognition: This is becoming more common and affordable with the advancements in camera technology and software. While it can be quite accurate, the cost-effectiveness has been improving, making it less categorized as "expensive."

4. Voice Recognition: Voice authentication is less accurate compared to the other forms and is typically more affordable. The variations in voice can lead to higher false rejection rates.

Conclusion

Among the listed options, Iris recognition stands out as the biometric authentication method that is both accurate and relatively expensive.
