Samsung’s rivals got the ball rolling on biometric security when it introduced the fingerprint scanner to the iPhone 5s and Senior Vice President Rhee In-jong said that Samsung is “following the market trend." Speaking in Hong Kong, he said, “We're looking at various types of biometric [mechanisms] and one of things that everybody is looking at is iris detection.”
Initially, any new security measures will feature in Samsung’s high-end flagships such as the Galaxy Note 4 and Galaxy S6, for example. However, it is hoped that these measures will trickle down to more budget-friendly devices in the future.
Rhee currently heads up Samsung's mobile enterprise service Knox, so it stands to reason that he hopes that biometric security measures become more prominent and that more users take advantage of the Knox service.
