Final answer:
Biometrics offer unique and secure identification, making them reliable and secure for authenticating e-business transactions.
Step-by-step explanation:
Biometrics offer significant promises as a way to authenticate e-business transactions because they provide unique and secure identification. Unlike traditional methods like passwords or PINs, biometrics use unique traits of the individual, such as fingerprints, iris patterns, or facial features, which are difficult to replicate. This makes it highly reliable and secure for authenticating transactions. While some forms of biometrics may require minimal training, such as fingerprint scanning on smartphones, others like facial recognition may need more extensive training to achieve better accuracy.
