Abstract

A system and method for monitoring and screening individuals subject to voluntary or mandatory personal conduct restrictions, such as prohibitions on alcohol and drug use, as well as geographic travel limitations using remote wireless communications and smartphone technology. A computer software program, including a Client Module and a downloadable Subject Module is preferably provided as part of the system to facilitate the execution of the method. Biometric verification of the Subject'"'"'s identity is achieved via wireless communication from the subject to the Client. A comparison of a first facial photograph obtained from the subject in a known, non- impaired condition with a current facial photograph obtained from the subject and wirelessly transmitted to the client provides a basis for determining a probability of cognitive impairment. GPS data obtained from the Subject'"'"'s smartphone enables compliance with travel requirements.

Claims

1. A system for remote monitoring and cognitive impairment screening of a Subject person by a screening entity, said system including:

a client computer platform including a computer processor and data storage device;

a client module computer software program stored on said data storage device;

a downloadable computer software application package;

a smartphone having said downloadable computer software application stored thereon;

said client module configured to wirelessly enroll the Subject by wirelessly receiving a biometric registration sample and a non-impaired baseline photographic still image of at least one of the Subjects eyes obtained from the Subject using said smartphone;

said client module configured to maintain Subject-specific data including said biometric registration sample, said non-impaired baseline image of said at least one of the Subject'"'"'s eyes, and personal conduct provisions;

an impairment test notification generated by said client module and wirelessly transmitted to said smartphone;

a biometric verification sample obtained from the Subject using said smartphone and wirelessly transmitted to said client computer platform;

an impairment verification image of at least one of the Subject'"'"'s eyes obtained from the Subject using said smartphone and wirelessly transmitted to said client computer platform;

an impairment verification results message including the results of an impairment test based on a visual comparison of said non-impaired baseline image with said impairment verification image, said impairment verification results message wirelessly transmitted to said smartphone;

said client module further including personal conduct provisions for the Subject, said personal conduct provisions including at least one provision selected from the group of;

(i) a geographic location restriction provision prohibiting travel to one or more locations based date and/or time;

(ii) a geographic location restriction provision restricting travel to within a predetermined radius based on date and/or time;

or, (iii) a geographic location mandate provision requiring travel to one or more locations based on date and/or time;

said client module periodically receiving GPS location data wirelessly received from the Subject'"'"'s smartphone, and generating an alert when the GPS data indicates that the Subject is not in compliance with one of said personal conduct provisions.

2. The system of claim 1, further including the remote activation, by said client module, of at least one of the Subject'"'"'s smartphone audio recording feature to record an audio file in response to said alert, and automatic wireless transmission of audio file from said smartphone to said client module.

3. The system of claim 1, wherein said client module transmits a signal disabling the Subject'"'"'s smartphone in response to said alert.

4. A wireless method for remote cognitive impairment screening of a Subject person by a screening entity, said method including the steps of:

providing computer software including a client module and a downloadable subject module;

installing said client module on a client computer system;

downloading said subject module to a smartphone possessed by the Subject;

obtaining a biometric registration sample from the Subject using said smartphone;

transmitting said biometric registration sample to said client for storage on said client computer system;

obtaining a baseline photographic image of at least one of the Subject'"'"'s eyes when the subject is not cognitively impaired using said smartphone;

transmitting said baseline photographic image to said client for storage on said client computer system;

wirelessly contacting said Subject via said smartphone and prompting said Subject to perform an impairment screening test;

obtaining a biometric verification sample from said Subject using said smartphone;

obtaining at least one impairment verification still image of at least one of the the Subject'"'"'s eyes using said smartphone;

wirelessly transmitting said biometric verification sample and said at least one impairment verification image to said client;

verifying the identity of the Subject by comparing said biometric verification sample with said biometric registration sample;

determining whether the Subject appears impaired by visually comparing said baseline photographic image with said screening photographic image;

programming said client module with personal conduct provisions for the Subject, said personal conduct provisions including at least one provision selected from the group of;

(i) a geographic location restriction provision prohibiting travel to one or more locations based date and/or time;

(ii) a geographic location restriction provision restricting travel to within a predetermined radius based on date and/or time;

or, (iii) a geographic location mandate provision requiring travel to one or more locations based on date and/or time

generating periodic wireless transmissions of GPS location data from said smartphone to said client platform;

generating an alert when said GPS location data deviates from said personal conduct provisions; and

remotely activating at least one of the Subject'"'"'s smartphone audio recording features in response to said alert, recording an audio file, and wirelessly transmitting said audio file from said smartphone to said client module.
