Authentication proofs are often grouped into the categories:
Something you know (like a password or PIN)
Something you have (like a smart card or dongle)
Something you are - this would be biometrics.
computer scientists are always trying to improve biometric authentication methods

A person would have to submit their coin to an authentication service. Then the service would prove if the coin is real or not and give a proof of authenticity if the coin was authentic.
Two factor authentication refers to two types of security in place to authenticate a person's identity. Two factor authentication is common in banking and providing health care information because of the sensitivity of this information. To create two factor authentication, you might create two separate passwords, ask for a password and an answer to a security question, require biometrics as authentication in addition to a specific pin code or question. There are an infinite number of combinations that can be put in place depending on your budget and the technology available in your location.

AnswerWell for one it only helps you. If someone wants to use your computer then they need you to unlock it. If you have a family then biometrics is a bad idea. Third biometrics is expensive. Some whole packages can be 1,000. For what! For inconvenience and debt. The third reluctancy is it really is no challenge for hackers to get past.AnswerIts very personal. Its one thing having a password, but a computer storing your fingerprints can be quite daunting.Its costly.Suprisingly biometrics arent as secure as you might imagine.About a year ago, a customer asked me to crack into his laptop, his only authentication method was a fingerprint scanner. The night before he came to me, he happend to burn his finger and it blistered. The following day he wasnt able to get into his laptop. So I guess that's another reason why you might be reluctant.
Biometrics takes advantage of your unique characteristics. Supposedly you are the only one with your fingerprints, voice, retinal patterns, iris, palmprint, face, etc. In theory, those characteristics can be used to uniquely identify you and access to rooms, computer systems, etc. can be granted or denied based on whether you are really you. This contrasts with other methods of access control - something you know (like username/password, PIN, etc.) and something you have (smart-card, magnetic key, physical key, token, etc.). In theory, no one else has all your biometric characteristics, but someone could possibly learn your password or steal your smartcard. In that respect biometrics are supposed to be more secure than the other methods. In practice, biometrics are still somewhat prone to both false positive and false negative failures. Most biometric identification methods can still be fooled at least some of the time by a very skillful intruder. For these reasons, when reliable authentication is very important, 2-factor or even 3-factor authentication is recommended, with biometric authentication being one of the authenticating factors.
Biometrics were first used to track local nationals overseas.
no one knows the authentication of bible but also it is so authentic like your authentication proof of being you are child of one father. (witty retort, I submit to your expertise.) The best proof of biblical authenticity,I've found,is Josh McDowell's popular book,'Evidence That Demands a Verdict'. You can't put it down. The older generation might point you to 'Who Moved the Stone'.
