Visa是一家著名的信用卡支付方法提供商,已开发了一种名为LucidiTEE的区块链驱动系统,旨在令多方共同计算大型私人数据。即使数据提供者处于离线状态,也可以确保遵循合规性。

Visa的研究与开发部门通过一份白皮书透露,该系统将通过算法确保公平,因为如果一方获得输出,则所有守规方都可以使用该系统。

 

LucidiTEE使用协议

LucidiTEE使用协议来保证所有计算遵从政策和公平性,即使任何一方的子集出出现恶意行为。

该论文称:“我们的协议(具有正式的安全性证明)用于公平的n方信息交换。它可以接受t <n的范围内任意的资料损毁,并且仅需要t个参与者来控制TEE节点。”

商品设备上的终端用户使用服务时可以确保他们资料的公平性。

此外,数据在受信任的执行环境(TEE)中得到处理,并利用基于历史的策略,能向所有参与者呈现任何计算输出。

LucidiTEE将首先应用于客户和金融应用程序之间的数据共享。该区块链系统据称可能允许银行将数据共享给机器学习算法以跟踪欺诈行为。
