Final answer:
Biometrics are used for enhancing personal security, securing financial transactions, and safeguarding medical information, playing a crucial role in maintaining privacy and protecting sensitive data in various sectors.
Step-by-step explanation:
Biometrics are commonly used for three main purposes: enhancing personal security, securing financial transactions, and safeguarding medical information. Individuals use biometric identifiers, such as fingerprints or facial recognition, to access devices or accounts, ensuring that only they have access to their personal information. Financial institutions employ biometrics to protect clients' accounts from fraudulent activities, and healthcare providers use them to maintain the confidentiality of medical records, in turn preventing misuse or wrongful disclosure of sensitive health data. Governments also rely on biometric technology to protect national security by keeping confidential information out of the hands of those who might harm the country.
The use of biometrics is vital for safeguarding individuals' privacy and maintaining the integrity of important operations across businesses, organizations, and governments.
