    人机物三元计算中的通用计算账户与个人信息资产代数

    Universal Compute Account and Personal Information Asset Algebra in Human-Cyber-Physical Ternary Computing

    • 摘要: 计算机科学技术的发展涌现出一些基础性的不变量,推动了学科的知识积累和信息产业的资本深化,近20年的一个不变量例子是万维网(WWW)中的资源概念.未来信息技术发展的一个重要方向是融合人机物三元世界的普惠计算,当前互联网服务、云计算、大数据领域的“以资源为中心”的模式将逐渐向“以用户为中心”的模式发展.个性化的普惠计算需要另一个不变量,即用户的通用计算账户.刻画了通用计算账户的基本性质与技术组成,并从个人用户数据角度,提出了个人信息资产及其资产代数的学术抽象和原型实现.分析和实验表明,通用计算账户和资产代数系统有利于克服现有系统存在的用户数据被锁定在各个服务与设备中,难以统一管理和共享的问题.

       

      Abstract: Invariant abstractions have played a fundamental role in knowledge accumulation and capital deepening in the field of computer science, of which an example in the past 20 years is the resource abstraction in RESTful Web services and cloud computing. An important direction in future computer science research is computing for the masses in a ternary universe of the human society, the cyberspace, and the physical world, whereby the resource-centric paradigm will shift to a user-centric paradigm, enabling personalization of future information products and services. This calls for a new invariant abstraction, i.e., a universal compute account (UCA) for each user to utilize human-cyber-physical resources in a tetherless and seamless way. This paper discusses the basic properties and organization of UCA, and presents a personal information asset algebra as well as a prototype implementation of the corresponding data asset management system. Analysis of experimental examples shows that the UCA and the asset algebra system facilitate data integration and sharing, thus alleviate the current problem that users personal data are scattered and locked in many vendors devices and services.
