Chill-Pass: Using Neuro-Physiological Responses to Chill Music to Defeat Coercion Attacks

摘要: Current alphanumeric and biometric authentication systems cannot withstand situations where a user is coerced into releasing their materials under hostile circumstances. Existing approaches of coercion resistant (CRAS) propose factors such as implicit learning tasks, which are non-transferable, but still have the drawback that an attacker can force victim (causing stress) to perform task in order gain unauthorized access. Alternatively, there could be cases claim they were giving up materials, whereas reality acted insider attacker. Therefore, being able detect stress during also helps achieve non-repudiation cases. To address these concerns, we need CRAS both non-transferable property well mechanism related coercion. In this paper, study feasibility using Chill (intensely pleasurable) music stimulus elicit unique neuro-physiological responses used authenticating factor for CRAS. stimuli neuro-chemical called Dopamine. However, release Dopamine at different parts brain, resulting responses, gives us stress-detection properties necessary We experimentally validated our proposed based human subjects measuring on prototype system. Based 100 samples collected from subjects, successfully authenticate with accuracy over 90\%. Our work not only demonstrates potential CRAS, paves path wider adoption general.
