Authorizing replacement of a security parameter associated with one or more exchange items

Abstract

A method for replacing a lost security parameter includes receiving, from a computing device of an exchange item marketplace network, a new security parameter adoption request for a replacement security parameter to replace the lost security parameter associated with one or more exchange items of the exchange item marketplace network. The method further includes determining a group of merchant servers of a plurality of merchant servers of the exchange item marketplace network to facilitate verification of the replacement security parameter. For each merchant server, the method further includes sending a corresponding portion of the replacement security parameter to a corresponding merchant server and receiving security verification information from at least some of the group of merchant servers. When receiving a threshold number of favorable verification results from the at least some of the group of merchant servers, the method further includes facilitating completion of replacing the lost security parameter.

         7 . The method of  claim 6 , wherein the receiving the security verification information from the at least some of the group of merchant servers comprises:
 receiving an indication of whether a verification result of the unique security verification code is favorable.   
     
     
         8 . The method of  claim 1 , wherein the facilitating completion of replacing the lost security parameter comprises:
 exchanging set up verification with an exchange item trusted module of the exchange item marketplace network, wherein the exchange item trusted module exchanges trust information with the exchange item issuing server with regards to the replacement security parameter.   
     
     
         9 . The method of  claim 1 , wherein the facilitating completion of replacing the lost security parameter comprises:
 modifying exchange item information associated with the one or more exchange items, wherein the exchange item information includes the replacement security parameter.   
     
     
         10 . The method of  claim 1 , wherein the facilitating completion of replacing the lost security parameter comprises:
 acquiring updated blocks of a blockchain associated with an exchange item of the one or more exchange items, wherein the updated blocks are signed with a private key associated with the replacement security parameter; and   storing the updated blockchain in a marketplace database of the exchange item marketplace network.   
     
     
         11 . A marketplace server comprising:
 memory;   an interface; and   a processing module operably coupled to the memory and the interface, wherein the processing module is operable to:   receive, from an exchange item issuing server of an exchange item marketplace network, a new security parameter adoption request for a replacement security parameter to replace the lost security parameter that is associated with one or more exchange items of the exchange item marketplace network;   determine a group of merchant servers of a plurality of merchant servers of the exchange item marketplace network to facilitate verification of the replacement security parameter;   for each merchant server of the group of merchant servers, send, via the interface, a corresponding portion of the replacement security parameter;   receive, via the interface, security verification information from at least some of the group of merchant servers; and   when receiving a threshold number of favorable verification results from the at least some of the group of merchant servers, facilitate completion of adoption of the replacement security parameter to replace the lost security parameter.   
     
     
         12 . The marketplace server of  claim 11 , wherein the processing module is further operable to determine the new security parameter adoption request includes one or more of:
