走红的“虹膜写真”安全吗？医生提醒……

Iris photography has become a new trend, with many online users and businesses sharing related photos on social media.

Capturing iris photos mirrors hospital eye exams, resulting in distinct iris images through photography and processing.

Many couples head to the studio for iris photography sessions, and some opt to have iris portraits taken with their beloved pets.

Some business owners claim that iris photography and iris recognition are distinct domains, and iris photography alone can't achieve biometric recognition. But experts caution that there could be potential risks.

The intricate texture features of the iris contain unique personal data of significance. While iris photography and iris biometric authentication diverge in technical principles, there exists a potential risk of malevolent actors exploiting iris photographs and associated techniques to compromise iris biometric authentication systems. 

Professor Xu Ming from the College of Cyber Security at Hangzhou Dianzi University advises minimizing the public display of iris photographs whenever possible.

Dr Yu Pingping, the ophthalmology director at the Second Affiliated Hospital of Zhejiang Chinese Medical University, explains that while iris photography, commonly used in medical settings, generally poses no harm to the eyes, exposure to intense light during capture could potentially harm the retina. She recommends avoiding strong light and direct eye contact with the source during photography, as well as limiting the frequency of sessions.

Patients with conditions such as keratitis, retinal diseases, or recent eye surgeries are cautioned against undergoing iris photography, as advised by Han Wei, deputy director of the Ophthalmology Center at the Second Affiliated Hospital of Zhejiang University School of Medicine.
