Method and System to Authenticate Interactive Children's Toys

摘要

A method and a system (10) which is capable of being implemented as a children's' toy. The system (10) is operable to interface an add-on device (20a) or a story to an interactive environment hosted by the system (10). The system (10) includes a response engine (30) which is operable to receive notification (225) from add-on devices introduced to the system (10). The response engine is operable to generate challenges (235) to the add-on devices (20a) wherein the challenges include watermarks embedded therein. The response engine (30) is operable to receive corresponding responses sent from the add-on devices (20a) in response to the challenges (235). Moreover, the response engine (30) is further operable to analyze the corresponding responses to determine whether or not the add-on devices (20a) are able to extract the watermarks correctly from the challenges (235) in generating the corresponding responses. The system (10) is thereby selectively capable of accepting the new devices (20a) to the system (10), thereby preventing counterfeit or copy products being used with the system (10).
