4. What’s the difference between verification and blind verification?

Explanation / Answer

[I am going to answer 1-3 questions. Thanks]

1. No, the latent prints are not unique. They are the impressions produced by the ridged skin on fingers, palms and soles of the feet in humans. To view the latent prints some sort of assistance is needed as they cannot be viewed by naked eyes.

2. Yes, research has been done but not on large scale.

3. The 2D impression are the blood, fingerprints etc which are present at the site while 3D impression is casting these evidences. It is a reliable process.
