AFIS and Livescan quality statement: They require good quality prints and cannot clear up poor quality.

• A. They require good quality prints and cannot clear up poor quality.
• B. They can clear up poor quality prints by comparison.
• C. They replace the need for old prints in the system.
• D. They are used only for non-criminal investigations.

Answer: (A)

AFIS and Livescan rely on extracting detailed ridge features from clear fingerprint images. The main idea is that image quality directly affects whether enough identifiable features can be detected for a reliable match. When a print is good, the system can generate a precise template and perform accurate comparisons. When the print is poor, there aren’t enough definite features to distinguish prints, and there isn’t a reliable way for the system to “clean up” the data to a usable level. That’s why this statement is correct: good quality prints are required and poor quality cannot be cleared up by the system. In practice, if prints are poor, technicians retake or re-scan to obtain a legible print before submission. The other options imply fixes or uses that don’t reflect how AFIS and Livescan operate.
