What is the meaning of fingerprint lock rejection rate? What does the fingerprint lock false rate mean? What are the industry standard parameters for fingerprint rejection rate and falsehood rate? The core part of the fingerprint lock is unlocked by the fingerprint, and the fingerprint information is read by the fingerprint head, and then the matching unlocking is performed. The recognition accuracy of the fingerprint head is directly related to the security performance of the fingerprint lock. In the common terminology of the fingerprint head, the refusal rate and falsification rate are often referred to. What does this mean? The refusal rate refers to the probability that the same fingerprint is recognized by the fingerprint algorithm as a different fingerprint. The refusal rate is also referred to as the rejection rate. The full name is: False Rejection Rate, the English abbreviation is FRR, and the fingerprint lock is true fingerprint information. The probability of recognition as a fake fingerprint. The refusal rate is the error probability that the fingerprint lock mistakenly considers the same fingerprint as a different fingerprint and refuses to unlock. The refusal rate calculation formula: FRR=(number of fingerprints that are known/the total number of fingerprints examined)*100%. According to the standards promulgated by the Ministry of Public Security, the refusal rate should be less than or equal to 3%, and the security level for home users must be above 3, and the refusal rate should be less than or equal to 0.1%. The falsehood rate refers to the probability that different fingerprints are recognized as the same fingerprint and the unlocking occurs, and the false fingerprint is mistakenly considered as the error probability of the real fingerprint. The false recognition rate is also known as misrecognition rate. It is called: False Accept Rate, English abbreviation FAR. The false-false rate calculation formula: FAR=(number of fingerprints mistakenly/the total number of fingerprints examined)*100%. According to the provisions of the Ministry of Public Security, the false-positive rate should be less than or equal to 0.001%. Fingerprint locks higher than this parameter are unqualified and users need to pay attention. The high refusal rate and falsification rate are very unfavorable for fingerprint locks. The two are related to each other to a certain extent. With the improvement of the technology, fingerprint locks will continue to reduce the parameters of both.
