Abstract
Verification of biosensor data by determining a tamper event. The tamper event can be detected as any event which attempts to spoof the system by obtaining incorrect or improper readings. One verification obtains a known image of the user and compares that with an image of the user which is taken at a time that the biosensor is placed in contact with the user skin. A similarity score between the known image and the taken image can be obtained, and a tamper alert generated when the similarity score is not sufficiently high to indicate a match.
Claims15
A system for detection of biosensor data comprising:
- a biosensor, having a skin proximity sensor which creates skin proximity sensor data when in contact with skin;
- an electronics system which wirelessly communicates said skin proximity sensor data;
- and
- an application running on a wireless device, which receives said skin proximity sensor, and also includes a camera, and which sends both said skin proximity sensor data, and image from the camera, to a network based computer which operates to determine if a tamper event has occurred using the image from the camera.
The system as in claim one, wherein the tamper event includes detecting an unauthorized person wearing the sensor.
A method for verifying detection of biosensor data from a wearer comprising:
- obtaining a known image;
- using a camera for obtaining an image of a wearer wearing a body-worn sensor;
- determining an image time, indicating when the image of the wearer was obtained;
- using a computer for comparing the image of the wearer to the known likeness, to determine a degree of similarity score between the image of the wearer and the known likeness;
- issuing a tamper alert if the degree of similarity falls below a predetermined value;
- obtaining skin proximity readings from the body-worn sensor;
- obtaining a proximity connection time that corresponds to a time at which skin proximity sensor values change to greater than a predetermined threshold which indicates that the skin sensor is in contact with skin;
- comparing the proximity connection time to the image time and establishing a tamper alert if a difference between the proximity connection time in the image time exceeds a threshold;
- and
- establishing the skin proximity readings as being valid when no tamper alerts have been detected.
