Hi Chaals, Here is a free link to the paper: http://arxiv.org/abs/1602.04115 Our solution suggests for requiring explicit permissions from the users. We also believe that the solutions available in the literature have failed to be practical. An industrial solution which has been applied by Chrome was decreasing the sampling rate (from 200Hz to 60Hz), which seems not successful too, since we reveal the PINs even on the frequency of 20Hz.

Or do the mitigations suggested in the conclusion look at either the use of vibration, e.g. the vibration API, to add noise to the data, or the little trick done by e.g. BancoSantander where they provide an onscreen keyboard that randomly shuffles key positions at each keypress? cheers Chaals -- Charles McCathie Nevile - web standards - CTO Office, Yandex chaals@yandex-team.ru - - - Find more at http://yandex.com
