零售巨头沃尔玛获得3项区块链相关专利

上周,全球规模最大的公司美国零售巨头沃尔玛从美国专利和商标局获得了三项与区块链相关的系统专利。

这些专利包括从一个区块链上获取医疗记录的系统,一个电网需求管理方法和系统,以及一个对锁定位置访问权限的管理系统。将拥有控制对锁定位置权限的访问系统。

沃尔玛基于区块链的医疗记录系统可将患者数据存储在分布式账本中,当病人遇到无意识的昏迷情况等紧急情况时,有关患者的医疗记录可以被授权访问。由于隐私问题,只有特定的紧急情况的医疗数据应存储记录应记录在区块链系统上。

该系统有三个关键设备,其中一个是具有分布式账本的本地存储媒介功能的可穿戴设备。手链将是可穿戴设备的理想选项。除此之外,还需要一个生物识别扫描仪来获取患者的生物特征(如指纹、虹膜或视网膜)以及用于扫描可穿戴设备的RFID扫描仪。这些都由沃尔玛于2016年12月提出专利申请。

除了医疗记录系统之外,沃尔玛还获得了区块链能源网络的专利。它将能够根据使用加密货币作为支付方式来控制及限制电力供应。这项专利申请由沃尔玛于2017年年底提交。该解决方案将有助于促进家用电器和其他设备的低效用电。该系统将允许向每个设备发放有限数量的加密货币。因此,用户可以在一段时间内购买适量的电力能源。

沃尔玛的第三个区块链相关专利指的是一个系统,该系统可以帮助用户安全地控制或限制对真实或虚拟空间的访问。系统使用存储在区块链中的加密密钥。

来自2018年4月的相关报道显示,沃尔玛已经为区块链产品及系统提交了两项专利申请。这家零售巨头希望利用该技术实现供应商支付共享系统和购物物流系统。

除沃尔玛之外,IBM已经获得了“防止区块链中的漏洞的系统和方法”的专利申请批准,而思科则为其信任启用去中心化资产跟踪系统(供应链和自动库存管理)打开绿灯。

US retail giant Walmart, the world’s largest company by revenue, received last week three patents from the US Patent and Trademark Office for several blockchain-related systems. The patents refer to a system for obtaining medical records on blockchain, a method and system for managing demand on an electrical grid, and a system for controlling access to a locked place. Besides Walmart, IBM and Cisco also saw their patent application approved last Thursday.

Walmart’s blockchain-based medical records system allows patient data to be stored in a distributed ledger. The medical records can then be accessed in emergency situations when a patient is unresponsive. Due to privacy issues, only medical data that is emergency-specific should be put on blockchain.

The system has three key devices, one of which is a wearable object that has the function of a local storage medium for the distributed ledger. A bracelet would be an ideal option for the wearable device. There is also a biometric scanner needed to get a patient’s biometric signature (like fingerprint, iris, or retina) and an RFID scanner used to scan the wearable device. Walmart filed the patent application in December 2016.

Aside from the medical records system, Walmart was granted a patent for a blockchain-based energy network. It will be able to cap the supply of electricity based on the use of a cryptocurrency as a method of payment. The company applied for the patent in late 2017.

The solution will help to combat inefficient electricity use by home appliances and other devices. The system will allow a limited amount of cryptocurrency to be issued to each device. Thus, the user can buy the right amount of energy for a certain period.

Walmart’s third blockchain-related patent refers to a system that can help users securely control or limit the access to a real or virtual space. The system uses cryptographic keys stored on a blockchain.

In April 2018, we reported that Walmart had filed two patent applications for blockchain-based products or systems. The retail giant wanted to leverage the technology for a vendor payment sharing system and a courier shopping system.

Besides Walmart, IBM has received a patent application approval for “systems and methods for preventing vulnerabilities in a blockchain,” while Cisco got the green light for its Trust Enabled Decentralized Asset Tracking System for Supply Chain and Automated Inventory Management.
