A method for a secure delivery of physical goods, involving associating a good unique identifier (GUID) to a package comprising the physical goods requested by a client, obtaining proof of identity parameters from a client associated with the transaction involving the physical goods before the delivery of the physical goods, where the proof of identity parameters are provided to the client by a trusted authority, computing a function using the proof of identity parameters, the GUID, and a certification key, wherein the certification key is computed by the trusted authority, delivering the physical goods to the client, when the result of the function is positive, certifying the delivery when delivery data obtained during the delivery of the physical goods match the proof of identity parameters, the GUID, and the certification key known to the trusted authority.
