Q : What is the biometric identification technology?
A : Yes, the use of human biological characteristics of an identity authentication technology. Biometrics is the sole (and the others). or Automatic Identification can be measured and verified by physical characteristics or mode of behavior, physical characteristics and behavior into features.

Q : What is AFIS?
A: AFIS (AB Automaed Fingerprint Idenification temáticos) refers to the computer input fingerprint image processing to achieve fingerprint classification, location, Morphological characteristics and extract details before extracting features based on the comparison and fingerprint recognition.

Q : Fingerprint Identification will be wrong?
A: Fingerprint identification error that may occur include : [FAR [FRR wrong, and wrong to refuse to accept ratio] ratio]. [FAR Acceptable error rate] - I mean the identification and adoption rate : [FRR refused ratio] are wrong identification I have been judged by the percentage of non - I. At present, the major brands of fingerprint 1/100000-1/1000000 usually between FAR, False 1/30-1/100 usually between the error rate is very low; Several other brands of fingerprint could also be users of the [security] [or] to facilitate the demand, adjusted FAR and FRR.

Q : network transmission speed fingerprint information about what can be done?
A: After testing in the state (for example : no other network stability interference), the pace will soon fingerprint identification. about 2-5 seconds to complete the action. If the user is the Automated Fingerprint Identification fingerprint authentication groups, In addition to the certification by the speed network speed impact, the impact will be an increase in the number of fingerprint files. At this time unable to predict that his client should be defined.

    Fingerprint recognition technology in the field of security advantages :
The loose - fingerprint recognition technology, and a fundamental proof of identity to prevent the replication of objects, delegate or copyright problems.
As we all know, the fingerprints of individuals born with the logo, it has two very important features :
     (1) different fingerprint different; (2) with a fingerprint pattern life is not going to change. With the rapid development of fingerprint technology, fingerprint identification equipment or identification system is the growing tendency of high-performance, low prices. Reliable feature extraction algorithm and compared the proposed algorithm for identifying individuals to provide an effective means of identification.
    1980s of the 20th century, along with personal computers, optical scanning technology innovation in particular the late 90s, the introduction and rapid development of fingerprint sensor, the fingerprint identification equipment and identification algorithms, for personal identification applications provide effective means.
Fingerprinting is the inherent signs, and can not be delegated to reproduce, fingerprint recognition technology to prevent identity camouflage, password burglary, illegal visits, thereby making reliable authentication.

    The following table shows the relative other fingerprint identification of the outstanding advantages :

	Susceptible to leakage	Easily reproduce	Easily masquerade	Lost easily forgotten
Password	YES	YES	YES	YES
Card	YES	YES	YES	YES
IC Card	NO	NO	YES	YES
Fingerprint	NO	NO	NO	NO

     Fingerprint identification products and the development prospects :
     Fingerprint identification technology is becoming more mature, and from the army, police and special industry with the application of the civilian market.
    In recent years, biological certification as a means to become more and more mature and emerging authentication techniques, and gradually began to enter the market. As an important human fingerprint characteristics with the following features :

    Fingerprinting is very clear : only the specific nature. According to the theories of fingerprints, two fingerprint matching characteristics on the probability of 10-50 12.
    Invariance : fingerprint strong relative stability.
    Dermal Regeneration : as long as it does not hurt, after his recovery, despite Ridge restitution; Portability : live fingerprint with fraud, carry no memory of fearing the loss of such characteristics;
    Fingerprint Identification Technology to benefit from the development of modern manufacturing technology and electronic integration, rapid and reliable algorithm. While fingerprint is only a small part of human skin, but a considerable amount of data for identification, compared to these data is not equal and not equal to the simple question, It requires enormous computing using fuzzy matching algorithm. Modern technology has enabled us to create electronic integrated manufacturing very small fingerprint image retrieval equipment, Meanwhile the rapid development of the computational speed of a personal computer or microprocessor in the computer can be shipped to more than two fingerprints count possible. The use of fingerprint authentication as the safest way is the most reliable identification, identification methods, It has been widely applied in public security, finance, social security and many other areas, is very legal effect certification means At present, but also the most mature technologies to achieve the recognition of the status of the most simple method.
