Samsung trademarked the name Galaxy Iris and Galaxy Eyeprint in US and South Korea last month, a filing of the monikers released shows, raising the possibility that the tech giant will apply iris-scanning technology to future phones.
In the filing Samsung said it could apply the name to a future smartphone or a tablet without elaborating.
Samsung made a similar filing in the US, media reports show.
Last month, Samsung launched the Galaxy Tab Iris in India that works with the local Aadhaar authentication -- a database collecting the iris and fingerprints of citizens there.
The 7-inch tablet's 5 megapixel back camera is armed with a sensor that can read the eyes of users. The company hopes it will be used for banking and e-governance services such as passport, taxation, healthcare, and education.
The company has applied finger-print recognition on its phones since the Galaxy S5, but the tablet is its first for iris-scanning.
