Abstract

The disclosure relates to systems and methods for tracking offender movement with RFID. Such a system can include a transponder associated with an offender and a radar module configured to determine a direction of a moving object passing within range of the radar module. The system can include a radio frequency identification reader situated near the radar module and configured to transmit an interrogating signal to the transponder and receive an identifying signal in response to the transponder receiving the interrogating signal. The system can include a server configured to receive data from the radio frequency identification reader and the radar module through a network, transmit the received data to a web service through the network, and receive an alert from the web service that a monitoring rule of a plurality of monitoring rules associated with the offender was violated.

Claims

1. A system comprising:

a transponder associated with an offender;

a radio frequency identification reader configured to transmit an interrogating signal to the transponder and receive an identifying signal in response to the transponder receiving the interrogating signal;

a server configured to receive data from the radio frequency identification reader through a network, transmit the received data to a web service through the network, and receive an alert from the web service that a monitoring rule of a plurality of monitoring rules associated with the offender was violated, wherein the radio frequency identification reader is a first radio frequency identification reader positioned within range of an origin of a path that the offender is to travel, wherein the plurality of monitoring rules include a first monitoring rule defining a direction that the offender is permitted to travel past the first radio frequency identification reader;

a second radio identification reader positioned within range of a destination of the path, wherein a second monitoring rule of the plurality of monitoring rules indicates that the transponder is to be detected by the second radio frequency identification reader within a first specified period of time; and

a third radio frequency identification reader situated within range of the path between the first radio frequency identification reader and the second radio frequency identification reader.

2. The system of claim 1, wherein a third monitoring rule of the plurality of monitoring rules indicates that the transponder is to be detected by the third radio frequency identification reader within a second specified period of time different from the first specified period of time.

3. The system of claim 2, wherein the system further comprises a fourth radio frequency identification reader situated such that when the transponder is along the path, the transponder is not within range of the fourth radio frequency identification reader.

4. The system of claim 3, wherein a fourth monitoring rule of the plurality of monitoring rules indicates that the fourth radio frequency identification reader should not detect the transponder while the offender is traveling.

5. A method comprising:

receiving data from a radio frequency identification reader, the data indicating a time the radio frequency identification reader detected a transponder associated with an offender, the data including a first unique identifier associated with the transponder and a second unique identifier associated with the radio frequency identification reader, and the data including an indication of a direction the offender was traveling;

sending the data to a web service and receiving, from the web service, an alert that a monitoring rule corresponding to the offender has been violated by the offender;

sending the alert to a mobile device associated with an entity responsible for the offender; and

wherein;

the radio frequency identification reader is a first radio frequency identification reader situated within range of an origin of a path; and

receiving data includes receiving data from a second radio frequency identification reader situated within range of a destination of the path;

receiving data includes receiving data from a third radio frequency identification reader situated along the path between the first radio frequency identification reader and the second radio frequency identification reader.

6. The method of claim 5, wherein sending the alert includes sending an indication that a monitoring rule indicating that the transponder is to be scanned by the second radio frequency identification reader within a first specified period of time is violated.

7. The method of claim 5, wherein sending the alert includes sending an indication that a monitoring rule indicating that the transponder is to be scanned by the third radio frequency identification reader within a second specified period of time is violated.

8. The method of claim 5, wherein receiving data includes receiving data from a fourth radio frequency identification reader situated such that it is not within range of the path.

9. The method of claim 8, wherein sending the alert includes sending an indication that a monitoring rule indicating that the transponder is not to be scanned by the fourth radio frequency identification reader is violated.

10. A system comprising:

a transponder associated with an offender;

a first radio frequency identification reader situated within range of an origin of a predefined path an offender is to travel;

a second radio frequency identification reader situated within range of a destination of the path;

a server configured to receive data from the first and second radio frequency identification readers through a network, transmit the received data to a web service through the network, and receive, from the web service, an indication that a monitoring rule relating to the offender was violated by the second radio frequency identification reader not detecting the transponder within a first specified period of time;

a third radio frequency identification reader situated along the path between the first radio frequency identification reader and the second radio frequency identification reader; and

wherein the monitoring rule indicates that the transponder is to be detected by the third radio frequency identification reader within a second specified period of time different from the first specified period of time.

11. The system of claim 10, wherein the system further comprises a fourth radio frequency identification reader situated such that when the transponder is along the path, the transponder is not within range of the fourth radio frequency identification reader.

12. The system of claim 11, wherein the monitoring rule indicates that the alert is to be transmitted in response to the fourth radio frequency identification reader detecting the transponder while the offender is traveling.

13. The system of claim 12, wherein the monitoring rule indicates that no alert is to he sent in response to detecting a violation of the monitoring rule.
