A method for detecting counterfeited and stolen merchandises based upon Content Protection for Recordable Media (CPRM) technology is disclosed. This method comprises the steps of marking object or group of objects with a readable identifier during the manufacturing, associating an independent authenticity certificate to the objects during their manufacturing, the authenticity certificate comprising at least the object identifier, the manufacturer certificate and the brand company certificate, being impossible to copy, to counterfeit, and to falsify, and by adding new records comprising the retailer certificates to the authenticity certificate. CPRM technology is used to encode the content of the authenticity certificate that contains an encrypted title key determined by hashing the media key and the media identifier, the certificate content encrypted using the brand company private key, or a random generated key, the media key block set by the media manufacturer, and the media identifier also set by the media manufacturer.
