Method and system for monitoring intoxication

Abstract

A method and system for monitoring a user's intoxication including receiving a set of signals, derived from a set of samples collected from the user at a set of time points; providing a sobriety task to the user proximal to a time point of the set of time points; generating a performance dataset characterizing performance of the sobriety task by the user; receiving a supplementary dataset characterizing a demographic profile of the user and/or a physiological state of the user; determining a set of values of an intoxication metric, derived from the set of signals; generating a predicted temporal profile of the intoxication metric for the user based upon the set of values, the set of time points, and the supplementary dataset; generating an analysis of the user's sobriety based upon the performance dataset and the predicted temporal profile; and providing a notification to the user based upon the analysis.

We claim: 
     
         1 . A method for detecting alcohol consumption by a user, the method comprising:
 collecting a biological sample from a user at a biological sample collection device;   collecting a supplementary dataset comprising a biometric signal, wherein the biometric signal is separate and distinct from the biological sample;   calculating an alcohol metric for the user based on:
 the biological sample; 
 the biometric signal; and 
 a custom alcohol response curve personalized to the user; 
   providing a notification to the user based on the alcohol metric.
