Abstract: A verification engine for verifying that a retailer is an authorized sales channel for goods created by a manufacturer includes a controller configured to receive a verification request from a purported retailer initiated by a customer seeking to purchase goods. The request includes verification data and a first signature. The verification data includes at least identification of the purported retailer and the goods manufacturer, and the first signature includes a result of an operation on the verification data by a cryptographic key provided by the purported retailer. The verification data is compared to a listing to determine if the purported retailer is an authorized retailer. If so, a second signature is generated and compared to the first. A message is sent to the customer verifying or denying a relationship between the purported retailer and the goods manufacturer based on one or more of the comparisons.
