I wonder how much power all the processing draws. Judging from the slow movements and the delayed update on the screens in this video, it's pretty heavy on the processor.

The accompanying paper[1] claims the phone lasts four hours running the current version of fingerIO, but also that improvements could be made to preserve power (such as reducing the sampling rate).

We need to immediately improve on PIN-code protection upon cash-withdrawal in ATMs. The problem has been there for a while, but man, it gets easier and easier.

Sorry, I'm not sure how this is relevant or if this sentence even makes sense. Can you explain?

Currently you can see everywhere ATMs are asking you to visually check that keypad and card-input looks exactly like on picture. With this technology, you don't need to make a fake keypad to "hear" PIN sequence, you could just "listen" to it from somewhere else, some place not seen well.

Earlier quoted context omitted.

Additionally, a number of these research programs take the source code and make a go of a small business product.

And in many cases the universities own the IP associated with the research that goes on in their departments so they keep the source and treat it like a company would treat a trade secret. It's likely Washington will patent this and try to license the patents.

What's the legal situation with these academic research papers? Am I allowed to implement an algorithm from a research paper and then either sell the software or release it as open source?

I assume other academics are allowed to reimplement methods in order to reproduce the result and to compare to their own methods. Can I do the same as a learning exercise?

No he means implicitly. By not providing everything the academic implicitly requests a conversation before providing everything. The request is never stated but is implied by the assumption that there is no other way to acquire everything.

Ah I misunderstood who was implicitly requesting the conversation, that makes sense.

I actually assumed that before. The way you had quoted it was revealing. My comment reeks of nerd-rage now that I re-read it. Damn italics. I should have mentioned that it would be fair to say: The academic wants an explicit request for everything. I can see how it would have been easy to misinterpret his statement in this way. It's true. It's just not what was stated.
