Samsung has increased its smartphone security features by adding an iris scanner.

This year, Samsung released three flagship smartphone models. The latest one is the Samsung Galaxy Note 7. The company claims that this is their most secure phone to date.

The Galaxy Note 7 runs on the Knox platform, a system that can protect both the mobile’s hardware and software. It also has a fingerprint scanner, which can unlock the device. The latest addition to the phone’s security feature is the iris scanner. This enables unlocking the phone using technology that relies on eye recognition.

Iris recognition technology uses infrared, a light invisible to the eyes, to examine the patterns in the iris—the part of the eye that determines its color. It is composed of wave-like patterns unique to every individual. The infrared brightens the iris to make the pattern easier to scan and recognize. The iris scanner then retrieves information from its database to verify the owner of the phone. This means that the owner’s iris must first be registered in the database. Once verified, the phone will be unlocked.

Samsung is not the only company that has integrated iris scanners in their smartphones. Microsoft and Fujitsu are also trying to integrate iris and fingerprint recognition into their devices’ scanners for security purposes. However, although many users find fingerprint scanners more convenient, iris scanners are more consistent. This is because the pattern of the iris does not change, whereas fingerprints can change over time.
