Abstract

According to a first aspect of the present disclosure, an electronic tamper detection device is provided, comprising a tamper loop, a processing unit and a storage unit, wherein the processing unit is configured to detect that the tamper loop is open and to store, if the tamper loop is open, data indicating that the tamper loop has been opened in said storage unit, wherein the storage unit is a non-volatile memory. According to a second aspect of the present disclosure, a corresponding tamper detection method is conceived. According to a third aspect of the present disclosure, a corresponding computer program is provided.

Claims

1. An electronic tamper detection device comprising a tamper loop, a processing unit and a storage unit, wherein the processing unit is configured to detect that the tamper loop is open and to store, if the tamper loop is open, data indicating that the tamper loop has been opened in said storage unit, wherein the storage unit is a non-volatile memory.

2. The tamper detection device of claim 1, wherein the processing unit is configured to store said data with added redundancy.

3. The tamper detection device of claim 1, wherein the storage unit is configured to allow said data to be stored only once.

4. The tamper detection device of claim 1, further comprising a communication unit, wherein the processing unit is configured to retrieve the stored data from the storage unit and to provide the retrieved data to the communication unit, and wherein the communication unit is configured to transmit said retrieved data to an external device.

5. The tamper detection device of claim 1, wherein the processing unit is configured to store said data during a start-up process of the tamper detection device.

6. The tamper detection device of claim 1, wherein the processing unit is configured to store said data during a tamper loop status reporting process of the tamper detection device.

7. The tamper detection device of claim 1, wherein the tamper loop comprises a conductive wire.

8. The tamper detection device of claim 1, being a near field communication tag or a radio frequency identification tag.

9. A closure comprising the tamper detection device of claim 1.

10. A seal comprising the tamper detection device of claim 1.

11. A tamper detection method using an electronic tamper detection device, the tamper detection device comprising a tamper loop, a processing unit and a storage unit, wherein the storage unit is a non-volatile memory, and wherein the processing unit detects that the tamper loop is open and stores data indicating that the tamper loop has been opened in said storage unit.

12. A computer program comprising non-transitory, executable instructions which, when executed by a processing unit, carry out or control the method of claim 11.

13. A computer-readable medium comprising the computer program of claim 12.
