Method and system for verifying ownership of a digital asset using a distributed hash table and a peer-to-peer distributed ledger

摘要

(600) and system (1) for verifying ownership of computer software prior to execution after installation using a distributed hash table (13) and a peer to peer distribution ledger (14). This may be a bit coin block chain or an alternative implementation. The method includes determining (610) a second user public key associated with a second user (24) from a transaction record stored on the peer to peer distribution ledger (14). The second public key associated with the second user may be determined 620 from an entry on the distributed hash table 13. The method further comprises comparing (630) a second public key to a second public key, and verifying (640) ownership of the computer software based on a comparison of the second user public key and the second public key .
