It may be possible to flash visual stimuli fast enough for it not to be consciously noticed — but for an EEG to still reveal whether the visual pattern was familiar or not.[0] The ERP circuit of interest is the P300 circuit.[1] Effectively a brain side-channel that could let someone fuzz your brain for pin codes while you type out jira tickets. 0: https://www.usenix.org/conference/usenixsecurity12/technical-sessions/presentation/martinovic https://www.usenix.org/conference/usenixsecurity12/technical... 1: https://en.wikipedia.org/wiki/P300_(neuroscience) https://en.wikipedia.org/wiki/P300_(neuroscience)
