解説
問 88
- ア
正解 Biometric authentication verifies a person's identity using physical or behavioral traits unique to that individual, such as fingerprints, veins, iris, face, or voiceprint. Choice ア, “the shape of the veins in a finger”, reads and matches exactly such a physical trait (a vein pattern), and it is a representative form of biometric authentication called vein pattern authentication. Therefore ア is correct.
Incorrectイ
Digital certificate authentication proves identity with a certificate the person holds (a possession based on public key infrastructure, PKI) and does not use any physical trait. Therefore it is not biometric authentication.
Incorrectウ
Judging by whether the characters in a hard-to-read string image can be read correctly is a mechanism called CAPTCHA, used to tell whether the other party is a human or an automated program. It is not identity authentication based on an individual's physical traits, so it is not biometric authentication.
Incorrectエ
A one-time password authenticates using a disposable password that is valid only for a limited time (information based on knowledge or possession) and does not use physical traits, so it is not biometric authentication.
ここがポイント
- Biometric authentication verifies a person's identity using physical or behavioral traits unique to that individual, such as fingerprints, veins, iris, face, or voiceprint.
- Digital certificates and one-time passwords are authentication based on possession or knowledge, and CAPTCHA distinguishes whether the user is human; all of these are distinct from biometric authentication.
