This article quotes the CEO of Image Ware,
[The solution] according to Miller, is multi-modal biometrics which he claims makes it virtually impossible for the wrong person to access computer systems.
His company uses existing hardware and platforms, connecting physical feature recognition algorithms (finger, palm, hand and prints, and face, eye, iris ) with other algorithms employing common biometric data sensors found on today's mobile devices.
My gut feeling is that he has overstated this somehow, but I can not put my finger on why this rings untrue. It seems to me that if a multi-sensor approach was truly effective we would see hardware and software for such strategies everywhere by now.
Can an IoT network of diverse sensors be an efficient and effective security strategy? (Is the multi-sensor approach effective? )
What are the pitfalls?
