Preliminary patent depositor Mastercard has requested protection for the umpteenth innovation blockchain, a platform that would allow anonymous blockchain transactions, using a method that is a little familiar.
In what has been compared to a coin mixing or tumbling service, the patent application published by the U.S. Patent and Trademark Office (USPTO) describes a system for dividing payments into separate transactions through a processing server to increase the anonymity of payments.
According to the filing, "The blockchain node can receive the request and can process the transaction to transfer the specific amount from the processing server's blockchain portfolio to that of the receiving device." In some embodiments, the processing server can notify the sending device and / or the transfer receiving device, which may also include the provision of a transaction record identifier for the second transaction. "
"As a result, the sender can transfer to the recipient a specific amount of digital currency with greater anonymity, because the blockchain can only reflect that the sender sent the currency to the processing server and that the recipient received the currency from the processing server. When using the processing server on multiple transactions and with multiple entities using the processing server, the true source or destination for any transaction is obscured to the point of being impossible to identify, "he noted.
Coinage or coin overthrow has been used for years in blockchain payments, provided as a service to crypto users. The process works by combining input transactions from multiple senders, combining them into a larger amount, then automatically distributing transactions from the recipient address, then separating the sender from the receiver for anonymous transactions.
According to the patent documentation, the Mastercard system would mean completely anonymous transaction data.
He explained: "If used for each transaction, a nefarious actor who observes transactions for the sender 104 will only see transfers to and from the processing server, thus revealing information about the sender's spending habits, thereby protecting the & rsquo; anonymity of the sender. "
In some embodiments, the processing server may use multiple blockchain portfolios to further increase anonymity. In such embodiments, the processing server may possess a plurality of different pairs of cryptographic keys. […] In some embodiments, the processing server can also render transactions anonymous by obscuring transfer amounts. In such embodiments, the processing server may interrupt the second transaction (e.g. transfer to the recipient's blockchain portfolio) in multiple transactions, where the total amounts from each of the transactions equals the specific amount that is transferred. to the recipient from the sender. In some cases, each transaction can transfer an equal amount of currency (for example, a total transfer of 36 currency units can be made in three transactions of 12 currency units). "
It is not clear how Mastercard intends to proceed with the patent. However, it demonstrates the growing number of use cases found for technology by companies like Mastercard, in recognition of the significant role that Blockchain is and will play more and more in the payments industry.
