A method includes initiating, by a computing device, an acquisition process with a merchant server to acquire an item using an exchange item. The method further includes determining, by the merchant server and/or a marketplace server, whether the acquisition process requires verification of the merchant server. When the acquisition process requires verification, the method further includes obtaining, by the marketplace server, a verification signature of the merchant server. The method further includes authenticating, by the marketplace server, the verification signature of the merchant server in accordance with use rules associated with the exchange item. When the verification signature is authenticated, the method further includes facilitating, by the marketplace server, exchange of the secure custody of the exchange item data file between the computing device and the merchant server in accordance with the secure custody protocol to finalize the acquisition process.
