Accuracy is another R&D issue, and price and complexity are lesser issues and can be mitigated somewhat if Samsung fabricated the relevant components themselves.
I am not sure where everyone is getting the idea that iris scanning takes some major breakthrough in technology. Sure, a system meant to scan a large number of people as they pass through an open area may cost a lot of money, but most of the costly components (lenses and tracking systems) wouldn't be necessary for a smartphone.
I finally found an article about Dr. Leonard Flom's work on iris scanning, although not the exact one I was wanting.
I am including an excerpt of the article ("Closing the Door on
Iris Recognition Vulnerabilities") from http://www.afcea.org/content/?q=node/11607.
"For now, the solution to that challenge is to combine a scan of the mother’s iris with an image of the baby’s ear, Flom offers. This provides four different elements for a database: both of the mother’s eyes, and both of the newborn’s ears. This approach has been tested successfully in Israel, he relates, because the research requirements there were less sclerotic than in the United States.
This effort also demonstrated that any conventional off-the-shelf image capture device will work “We can use an iPhone, an iPad, even Google Glasses as well as any digital camera,” he observes."
To clarify, they used off-the-shelf (the other article that I read said iPhones, I believe, but I cannot find it again) image capture devices to do their research. The actual capture of the image doesn't require much if any change to what is in any smartphone today. What it will require is a fortification of the hardware end, like what Apple did for TouchID, and a fast algorithm.
Personally, I think that this as much as anything is why Samsung is pursuing iris scanner tech. It really doesn't require them to make any changes to implement it. Of course, there is a difference between implementing and implementing well.
