The digital property management system comprises a sender's digital property manager and a recipient's digital property manager. The sender's digital property manager further comprises a sender's module and a sender's transaction node and the recipient's digital property manager further comprises a recipient' module and a recipient's transaction node. To increase anonymity of a remittance transaction between, sender's mpdule is not allowed to access a recipient's virtual identification. Thus, recipient's module generates a token to temporarily replace a recipient's virtual identification. To increase anonymity, an encrypted label is generated for each sub-transaction to identify sub-transactions and their sequence in the same remittance set.
