Abstract

A method and system for remotely monitoring intoxication of a user, comprising: prompting the user to provide a breath sample at a time point; at a breath sample acquisition device, generating a breath sample signal upon reception of the breath sample from the user, and broadcasting a unique signature proximal in time to the time point; using a sensor of a mobile computing device, generating an authentication signal derived from detection of the unique signature; at a processing system in communication with the mobile computing device and the sample acquisition device, receiving the breath sample signal and the authentication signal; generating a verification assessment that validates provision of the breath sample by the user; determining a value of an intoxication metric for the user based upon the breath sample signal; and transforming the verification assessment and the value of the intoxication metric into an analysis of intoxication of the user.

Claims

1. A method for remotely monitoring intoxication of a user, comprising:

at a first sample acquisition device in communication with a mobile computing device of the user, transmitting a first sample signal, derived from reception of a first sample from the user within a time interval, to the mobile computing device;

at a second sample acquisition device in communication with the mobile computing device of the user, transmitting a second sample signal, derived from reception of a second sample from the user contemporaneously with reception of the first sample signal;

using an imaging sensor of the mobile computing device, generating an authentication signal derived from a sequence of images of the user captured within the time interval;

at a processing system in communication with the mobile computing device, receiving the first sample signal, the second sample signal, and the authentication signal; and

generating an intoxication metric, based on the first sample signal, the second sample signal, and the authentication signal.

2. The method of claim 1, wherein the first sample comprises a breath sample, and wherein the second sample comprises a fluid sample collected from a body region of the user in contact with the second sample acquisition device.

3. The method of claim 2, further comprising prompting the user to generate a vibratory input to the first sample acquisition device during provision of the breath sample.

4. The method of claim 1, further comprising detecting a facial characteristic of the user in the sequence of images, and generating the authentication signal based on a comparison of the detected facial characteristic with a database of user facial characteristics.

5. The method of claim 1, further comprising prompting the user to provide fingerprint data at the mobile device within the time interval, and wherein generating the authentication signal is based on the fingerprint data.

6. The method of claim 1, further comprising transmitting a notification to a remote entity in response to the intoxication metric exceeding a threshold value.

7. A method for remotely monitoring intoxication of a user, comprising:

at a first sample acquisition device in communication with a mobile computing device of the user, transmitting a first sample signal, derived from reception of a first sample from the user within a time interval, to the mobile computing device;

at a second sample acquisition device in communication with the mobile computing device of the user, transmitting a second sample signal, derived from reception of a second sample from the user contemporaneously with reception of the first sample signal;

using a sensor of the mobile computing device, generating an authentication signal that associates the user with the transmitted first sample signal and second sample signal within the time interval;

at a processing system in communication with the mobile computing device, receiving the first sample signal, the second sample signal, and the authentication signal; and

generating an intoxication metric based on the first sample signal, the second sample signal, and the authentication signal.

8. The method of claim 7, wherein the first sample comprises a breath sample, and wherein the second sample comprises a fluid sample collected from a body region of the user in contact with the second sample acquisition device.

9. The method of claim 7, wherein the sensor comprises an imaging sensor, wherein generating the authentication signal comprises generating the authentication signal from a sequence of images of the user captured within the time interval at the imaging sensor.

10. The method of claim 9, further comprising detecting a facial characteristic of the user in the sequence of images, and generating the authentication signal based on a comparison of the detected facial characteristic with a database of user facial characteristics.

11. The method of claim 7, further comprising transmitting a notification to a remote entity in response to the intoxication metric exceeding a threshold value.

12. The method of claim 7, wherein the intoxication metric comprises a first portion based on the first sample signal and a second portion based on the second sample signal, and further comprising transmitting a notification to a remote entity in response to the first portion exceeding a first threshold value and a second portion exceeding a second threshold value.

13. The method of claim 7, further comprising prompting the user to generate a vibratory input to the first sample acquisition device during provision of the first sample.

14. The method of claim 7, further comprising prompting the user to provide fingerprint data at the mobile device within the time interval, and wherein generating the authentication signal is based on the fingerprint data.

15. A method for remotely monitoring intoxication of a user, comprising:

at a first sample acquisition device in communication with a mobile computing device of the user, transmitting a first sample signal, derived from reception of a first sample from the user within a time interval, to the mobile computing device;

using an imaging sensor of the mobile computing device, generating an authentication signal derived from a sequence of images of the user captured within the time interval;

at a processing system in communication with the mobile computing device, receiving the first sample signal and the authentication signal; and

generating an intoxication metric, based on the first sample signal and the authentication signal.

16. The method of claim 15, further comprising transmitting a second sample signal, at a second sample acquisition device in communication with the mobile computing device of the user, derived from reception of a second sample from the user contemporaneously with reception of the first sample signal.

17. The method of claim 16, wherein the first sample comprises a breath sample, and wherein the second sample comprises a fluid sample collected from a body region of the user in contact with the second sample acquisition device.

18. The method of claim 16, further comprising prompting the user to generate an auditory input to the second sample acquisition device within the time window.

19. The method of claim 15, further comprising transmitting a notification to a remote entity in response to the intoxication metric exceeding a threshold value.

20. The method of claim 15, further comprising detecting a facial characteristic of the user in the sequence of images, and generating the authentication signal based on a comparison of the detected facial characteristic with a database of user facial characteristics.
