Abstract

A wearable accessory controls (103) and provides security for a pill delivering medical substances and services. An initialization procedure allows decryption information (814) to be loaded into the accessory for each pill and/or decryption information (818) about the accessory to be loaded into the pill. The pill preferably sends encrypted messages to the accessory and the accessory preferably sends encrypted messages to the pill. The pill operates only when the proximity of the accessory is verified or authenticated during the operation of the pill, preferably at frequent intervals. Where the pill is no longer useful, its information can be deleted (1205) from memory in the accessory or other controlling device.

Claims

1. A pill (101) comprising:

a wireless transceiver (102);

at least one device (205) adapted to deliver a substance and/or service; and

at least one processor (204) adapted to perform operations, the operations comprising;

seeking an accessory for initiating (702) secured communication; and

refraining or blocking (704) delivery of the substance and/or service if the accessory is not found.

2. A medical security device comprising:

at least one wearable accessory (103, 105) the accessory comprising;

at least one wireless transceiver (104);

at least one memory device (302) for storing data and/or executable code; and

at least one processor (301, 303) adapted to execute operations including

sending at least one message to at least one pill (101) via the wireless transceiver; and

/or

receiving at least one message from the at least one pill (101) via the wireless transceiver.

3. The device of claim 2, wherein the operations further comprise receiving (606) encryption related information for said at least one pill, wherein the sending at least one message comprises encrypting and the receiving at least one message comprises decrypting with the received encryption related information.

4. The device of claim 2, wherein the operations further comprise storing encryption related information unique to the wearable accessory for said at least one pill, wherein the sending at least one message comprises encrypting and the receiving at least one message comprises decrypting with the stored encryption related information.

5. A system comprising:

at least one ingestible pill resident in the alimentary tract of a human body (100); and

at least one wearable accessory, the accessory comprising at least one wireless transceiver (104), at least one memory device (302) for storing data and/or executable code, and at least one processor (301, 303) adapted to execute operations including establishing secure communication with at least one pill (101) for enabling pill functionality, and monitoring or controlling the pill via encrypted messaging.

6. The system of claim 5, wherein the accessory (1302) is pre-equipped with information about at least one pill (1303).

7. The system of claim 5, wherein the accessory is programmed to monitor and/or coordinate delivery of substances and/or services by a plurality of pills and is programmed with respective encryption related information about at least two pills and each message (1401) is encrypted using respective encryption information associated with a particular pill.

8. The system of claim 5, wherein the device is programmed with respective encryption related information about at least two pills and each message (1401) is encrypted using respective encryption information associated with a particular pill.

9. The system according to claim 5, wherein secure communication is established between said accessory and at least one pill from security related information about the wearable accessory stored in the pill (818) and/or from security related information about the pill stored in the wearable accessory (606, 814).

10. The system according to claim 5, wherein establishing secure communication comprises:

associating one wearable accessory (808) with a set of pills (809); and

programming the wearable accessory (808) with security information regarding the pills (809).

11. The system according to claim 5, wherein data regarding medical substances or services to be delivered by the pills is stored in the wearable accessory.

12. The system according to claim 5, wherein the establishing communication comprises adding information about at least one new pill to a wearable accessory previously programmed with information about at least one prior pill.

13. A method comprising executing the following operations in a medical security system:

maintaining a close proximity between at least one wearable accessory (103) and a human body (100);

passing at least one pill (101) through the alimentary tract of the body (100);

performing a security related operation (703), to verify identity of either the wearable accessory to the pill, or to verify identity of the pill to the wearable accessory, or to verify the identity of the pill and the wearable accessory to each other.

14. A medium readable by a data processing device and embodying executable code for causing the device to perform operations, the operations including:

receiving information (821, 813) regarding at least one pill (809) and at least one wearable accessory (808);

establishing communication with the pill and/or the wearable accessory; and

programming either the wearable accessory or the pill or both with information (818, 814) about the other.

15. An apparatus (103) comprising:

at least one wireless transceiver;

at least one storage device embodying data and/or executable code in a machine readable form;

at least one processor adapted to perform operations, the operations comprising;

maintaining identifying information (1201) about at least one pill;

sending and/or receiving information (1202) relating to delivery of at least one service and/or substance to and/or from the pill, while the pill is in a human body;

determining (1204) that further communication with the pill is no longer useful; and

deleting (1205) the identifying information about the at least one pill that is no longer useful.
