How to get biometric retinal data for person identification?
Retinal data is, by far, the hardest to obtain for personal identification.
Retina recognition is considered as highly unique and reliable outperforming even fingerprint modality, At the same time, it’s quite challenging to deploy it due to a number of reasons.
First, it’s difficult to capture retinal data because of the eye anatomy. To do that, specialized equipment — fundus photography and ophthalmoscopes — should be used.
Second, retinal recognition and liveness detection demand cooperation from a person. Typically, a procedure includes three stages: eye positioning, gazing and focusing. Therefore, it becomes intrusive and requires more processing time unlike facial or voice recognition, which respond instantly.
