Embodiment Construction

[0025] The application will be described in further detail below in conjunction with the accompanying drawings.

[0026] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0027] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0028] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random acce...

Abstract

The invention aims at providing a method and equipment for ensuring data correctness. Compared with the prior art, the method comprises the following steps of: receiving a data processing request submitted by service equipment by a log server; when a log corresponding to the data processing request is generated, distributing globally unique log identification information for the log; obtaining thelog corresponding to the data processing request by the service equipment from the log server and sending the log corresponding to the data processing request to storage equipment; and comparing thelog identification information with current identification information stored by the storage equipment by the storage equipment, and if the log identification information is smaller than the current identification information, rejecting the data processing request. According to the method and equipment, the problem of wrong data consistency is solved.

Description

technical field [0001] The present application relates to the computer field, and in particular to a technology for ensuring data correctness. Background technique [0002] Data transmission in the network, especially when it is transmitted across countries and regions, involves a large number of network transmissions, distributed process scheduling, data synchronization and processing, and data consistency errors are prone to occur, such as TCP network delays, TCP network packet loss, and data writing. Into an exception, etc. Contents of the invention [0003] An object of the present application is to provide a method and device for ensuring data correctness, so as to solve the problem of errors in data consistency. [0004] According to one aspect of the present application, a method for ensuring data correctness is provided, wherein the method includes: [0005] The log server receives the data processing request submitted by the service device, and generates a log c...
