A cloud manufacturing user data management and control method based on labels

Abstract

The invention discloses a cloud manufacturing user data management and control method based on labels and belongs to the technical field of data management and control. In order to resolve various safety problems existing in user data transmission, share, and use processes in cloud manufacturing data chain, the invention provides a management and control method for transmitting, sharing, and using data between cloud manufacturing users under the circumstance of unconsolidated data storage. Using digital label technology, the method performs inseparable fusion on data and digital labels so as to guarantee the safety and the controllability in the use, the share, and the transmission processes of user data, achieve control and management of the full life circle of the data, and trace the source of a data leakage behavior.

Description

technical field [0001] The invention belongs to the technical field of data management and control, in particular to a data management and control method for cloud-manufactured user data links. Background technique [0002] Cloud manufacturing is a new network-based, service-oriented intelligent manufacturing model, and it is cloud computing in the manufacturing field. Cloud manufacturing has brought about great changes in the manufacturing industry. It enriches and expands the resource sharing content and service mode of cloud computing, and promotes the agility, service, green, and intelligence of manufacturing. Cloud manufacturing can realize the comprehensive sharing and collaboration of manufacturing resources, capabilities, and knowledge. The transfer, sharing, and use of knowledge and data among users constitute the data chain of cloud manufacturing. The data chain of cloud manufacturing runs through the entire life cycle of cloud manufacturing. Protection and contro...

AI Technical Summary

Problems solved by technology

In cloud manufacturing, although the user encapsulates manufacturing resources and capabilities and accesses the cloud, in general manufacturing scenarios, the user only provides a specific interface to the cloud. When the user performs specific tasks, the data will be out of the control of the cloud. Can directly access all kinds of data, so there is a risk of data management and control failure

[0004] 2. Existing solutions cannot meet the data chain protection requirements of cloud manufacturing

At present, data security protection products in the cloud computing environment mainly guarantee the privacy and integrity of static data and the reliability and availability of dynamic data. However, in the data chain protection and control of cloud manufacturing, more attention is paid to the The security and controllability of transmission, sharing and use between users, the expected goal is the controllability and non-repudiation of data in the process of use, so the existing data protection scheme cannot be directly applied to the security protection of dynamic data

[0005] 3. Existing solutions are difficult to control the use of authorized user data

The current data security protection in the cloud computing environment can prevent unauthorized users from accessing data, but in the data chain of cloud manufacturing, authorized users must access data under strictly controlled conditions (limiting the use time limit and frequency of data, etc.) , the behavior control of authorized users is difficult to achieve with existing solutions
