Which recognition method specifically uses iris and retinal patterns?

Explanation:
Eye-based recognition focuses on patterns found in the eye itself. The iris contains a highly unique texture, and retinal recognition examines the vascular pattern at the back of the eye; both are specific to the eye, which is why this category is described as Eye Recognition. Other modalities rely on different biology: facial recognition uses facial features, fingerprint matching uses skin ridges, and voice recognition uses vocal traits.
