A system and method are described which provides the ability to securely transfer ownership of digital sequences, or verify ownership, without the need to place trust in a third party, and without risk of anyone stealing or modifying the digital sequence. The system uses hash functions and linked records to create a transaction history for a digital sequence. The digital sequence may be used to represent another digital object. Each record contains fields generated using one or more hash values known to the owner. An owner transfers ownership by publishing an additional record or records in which the hash values are revealed and the new owner inserts fields generated using one or more hash values known to the new owner. An owner can demonstrate ownership by publishing a further record or record which reveals the hash values used to generate fields in the previous record. |
