Abstract
An apparatus may comprise an electronic circuit configured to perform one or more functions or operations, and a memory associated with the electronic circuit. The memory stores a customer-side circuit identification (ID) comprising watermark value combined with a pseudo-random number that is generated as a function of a seed value, wherein the seed value is based on a timestamp generated by computer. An external interface may be coupled to the memory, wherein the external interface provides read-access to the customer-side circuit ID.
