Which of the following methods is used to compare fingerprints for identification?

The method that is used to compare fingerprints for identification is not signature analysis, but rather fingerprint analysis itself. Fingerprint analysis relies on the unique patterns of ridges and valleys found in fingerprints to establish identity. The comparison process involves examining the minutiae points—specific features such as bifurcations, ridge endings, and other unique characteristics of the fingerprint.

Signature analysis typically involves examining a person's signature rather than fingerprints, which are distinct and have their own systematic methods of examination and comparison. Therefore, identifying a person through their fingerprints involves specialized techniques and databases specifically designed for that purpose, making fingerprint analysis the correct choice.
