I heard about this one company that had a similar idea but implemented it via a high frequency acoustic signature; the higher the frequency the stronger the encryption. It apparently turned into this nightmare of competing signatures and people couldn't think straight near the more secure connections. This scent technology seems to be less intrusive.
When you get different scents, will the wiffi emitters automatically sychronised with other nearby emitters so the distinct carrier smells don't interact and cause service ambiguity?
