Among them, a patent on the realization of anonymous transactions in the blockchain network is eye-catching. MasterCard first applied for the patent in December 2016 and was awarded by the USPTO on Thursday.
MasterCard said that for companies and consumers, the transparency of blockchain transactions hinders their use in daily payments.
On the corporate side, most companies do not want to provide their own real-time data (such as transaction volume) to competitors and other third parties. Consumers want to avoid letting others know the details of their transactions while they are spending.
“So we need a technology to solve this difficulty. This technology publishes the details of the transaction in the process of participating in the transaction to ensure the reliability and trust of the data. At the same time, it identifies the information of both parties and tracks part of the information of a single transaction. (such as transaction volume) to provide anonymity services to meet the confidentiality needs of each entity involved in the transaction.”
For example, consumers may not want others to know the details of their transactions while they are spending, and companies do not want to provide their real-time data (such as transaction volume) to competitors and other third parties. This is a difficult problem to solve.
This technology is to participate in the transaction process of the transaction details public release to ensure the reliability and trust of data. At the same time, the information of both parties can be identified to meet users’ confidentiality requirements and provide anonymous services
At present, there are many cryptocurrencies on the market that can achieve anonymous transactions, such as Monroe and zcash.
But MasterCard wants to promote anonymous transactions through third-party processors without using public cryptocurrencies.
The system proposed by MasterCard relies on a third-party processing server, which maintains the entity database by a third-party processing server. In addition to the identification information, each entity profile also contains a string of encrypted data.
MasterCard has previously obtained a number of blockchain patents, such as semi-private or private chains for systems that receive and store identity data, and travel agencies that actively meet the needs of visitors on the chain. MasterCard also hopes to provide law enforcement with the ability to track illegal transactions through this patent, but this patent does not have a clear solution.
