Authentication devices that recognize thumb print, retinal pattern, or facial pattern?

Appeared in: AIIMS Raipur NO - 2019 (Shift-2)

Explanation

Biometric authentication uses unique, measurable biological characteristics to verify a person's identity.
These characteristics can be physiological (related to the body's structure) or behavioral (related to patterns in actions).
Examples mentioned in the question, such as thumbprints, retinal patterns, and facial patterns, are all forms of physiological biometrics.
This technology provides a secure and reliable method for controlling access to sensitive information and areas, which is crucial in healthcare.

Option A: Bioethics is the study of moral principles and values in healthcare, not a type of technology.
Option B: Biophysics applies physics principles to biological phenomena. It does not deal with identity verification.
Option C: Biochemistry is the study of chemical processes in living things, like metabolism or enzyme reactions.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Biometric Authentication as background academic context rather than a clinical decision trigger.
Nurses frequently use biometric authentication to log into Electronic Health Records (EHRs) and access automated medication dispensing cabinets (e.g., Pyxis, Omnicell).
This enhances security by ensuring that only authorized personnel can access patient data and medications, creating a clear audit trail and reducing the risk of password sharing.
What if? - If a nurse's fingerprints are not recognized due to wearing gloves, wet hands, or a skin condition, they must use a backup authentication method, such as a unique PIN or an ID card swipe, to access systems and maintain workflow without compromising security.

How to Approach the Question

First, analyze the question stem to identify the core concept. The question asks for the term describing authentication using physical traits like fingerprints and facial patterns.
Read each option carefully and define it in your mind.
Option A, Bioethics, relates to morals in medicine.
Option B, Biophysics, relates to the physics of biological systems.
Option C, Biochemistry, relates to the chemistry of living organisms.
Option D, Biometric, relates to measuring biological data.
