Behavioral biometrics are particularly useful in continuous authentication systems, where the user’s identity is verified throughout the session. While promising, this technology is still evolving and faces challenges related to variability in user behavior.

The Advantages of Biometric Technology

Enhanced Security

Biometric technology significantly enhances security by providing a higher level of assurance that the person being authenticated is indeed who they claim to be. Unlike passwords or tokens, biometric traits are unique and cannot be easily duplicated or shared. This makes it much harder for unauthorized individuals to gain access to sensitive information or secure areas.

Convenience

One of the most significant advantages of biometric technology is its convenience. Users do not need to remember complex passwords or carry around physical tokens. Instead, they can use something that is always with them—their biometric traits. This ease of use can lead to higher adoption rates and improved user satisfaction.

Reduced Fraud

Biometric systems can greatly reduce the incidence of fraud. For example, in financial transactions, biometrics can ensure that the person initiating the transaction is the legitimate account holder. This can help prevent identity theft and unauthorized access to accounts. Similarly, in healthcare, biometrics can ensure that medical records are accessed only by authorized personnel, protecting patient privacy.
