CLAIMS

I claim,

1. A system for enabling identification of tampering, the system comprising a device engaged to an article the device comprising:

a movable member; and

a first reference provided on the movable member, wherein,

the device is operable to assume a first state and a second state;

position of the movable member changes at each instance the device is brought back to the first state; and

orientation of the movable member is determined by determining spatial orientation of the first reference with respect to a second reference, wherein the second reference is external to the movable member.

2. The system as claimed in claim 1, wherein the second reference is stationary when the device assumes the first state and the second state.

3. The system as claimed in claim 1, wherein the first reference and the second reference are machine readable.

4. The system as claimed in claim 1, comprising a label, wherein:

the label is affixed to the movable member; and

the first reference is present in the label.

5. The system as claimed in claim 1, the first state is a lock position and the second state is an unlock position, wherein,

the device, in the lock position, restricts access into an article which is locked by the device; and

the device, in the unlock position, allows access into an article which is locked by the device.

6. The system as claimed in claim 1, comprising at least one processor configured to: receive orientation of the movable member in the first state at a registration phase; receive orientation of the movable member in the first state at a verification phase; compare whether the orientation of the movable member in the first state received at the verification phase is same as the orientation of the movable member in the first state received at the registration phase; and

indicate tampering of the device if the orientation of the movable member in the first state received at the verification phase is not same as the orientation of the movable member in the first state received at the registration phase.

7. The system as claimed in claim 1, wherein the device is dis-engageable from the article by operating the device to assume the second state, and reusable to engage the device to another article.

8. The system as claimed in claim 1, wherein at least a position, which is visible to human eye, of the movable member, has a generally circular configuration.

9. The system as claimed in claim 8, wherein the movable member comprises a peripheral configuration, which limits human ability to compare between positions assumed by the movable member.

10. The system as claimed in claim 1, wherein the movable member comprises a pattern that limits human ability to distinguish the first reference in the pattern.

11. The system as claimed in claim 1, wherein the device comprises a smart tag configured to:

report previously logged data at each instance of scanning of the device; and

validate the reported data upon validation of the spatial orientation of the first reference with respect to the second reference.

12. The system as claimed in claim 1, wherein the device comprises a smart tag that is placed below a label, affixed to the movable member, comprising the first reference in a manner that any tampering of the smart tag results in tampering of the spatial orientation of the first reference with respect to the second reference.
