Abstract: A method and system are described for protecting a manufactured item from counterfeiting. The manufactured item, which is marked with an identifier, such as a serial number, is associated with a code generator that has secret functions and data for generating verification codes. The manufactured item is then supplied along with the corresponding code generator. Thereafter, the identifier from the manufactured item and the verification code generated by the code generator are used to verify authenticity of the manufactured item.

Abstract: In a system and method for initiating warranty coverage and providing warranty status for a manufactured item, an electronic device with a destructible extrusion is associated and supplied with the manufactured item, where detachment, unplugging, cutting, or tearing of the destructible extrusion is detected and initiates warranty coverage. The electronic device with the destructible extrusion is then attached in such a way as to require detachment, unplugging, cutting, or tearing of the destructible extrusion during an event that is appropriate to initiate warranty coverage. This may be the opening of the manufactured item's package, or it may be required before the manufactured item can be put to use.

Abstract: In a method and system for providing anti-counterfeit and product safety to a manufactured item, two substantially unique verification codes, one readable and the other hidden, are associated and supplied with the manufactured item. The verification codes are initialized to a first state at a validation service. Either or both codes may be submitted to a validation service for validation for any number of occasions, with the validation service responding with a message appropriate to the current state of the code. When the hidden verification code is exposed and submitted to the validation service for validation, a first successful validation is used as an event that triggers a state transition of both the readable and the hidden verification codes from the first state to a second state.
