Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] It should be understood that the embodiments described here are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] figure 1 It is a schematic frame diagram of an intranet and intranet data synchronization system 100 according to an embodiment of the present invention.

[0036] The internal and external network data synchronization system 100 includes an internal network server 110 and an external network server 120 . The internal and external network data synchronization system 100 is a system under the condition of physical isolation between the internal and external networks. The internal network ...

Abstract

The invention provides a method and a device for synchronizing internal network data and external network data. The method comprises the following steps: performing hash operation on first data of aninternal network stored by an external network, so as to obtain a first hash value; verifying the integrity of the first data according to the first hash value when the external network runs; and synchronizing the first data stored in the internal network into the external network when it is determined that the integrity verification of the first data fails. According to the method and the devicefor synchronizing the internal network data and the external network data, the legality and the consistency of the data under the condition of network physical isolation can be guaranteed.

Description

technical field [0001] The invention relates to the field of data synchronization, in particular to a method and device for synchronizing internal and external network data under the condition of network physical isolation. Background technique [0002] With the development of information technology, the network has brought great convenience to people's work and life. However, network security has also become a severe test for us. Especially in some areas that require high system and data security, in addition to protecting the system itself, there are also relatively high restrictions on network access. [0003] At present, the data synchronization between existing databases is carried out in an online environment, but in the data synchronization between different databases with high security requirements and physical isolation between internal and external networks, most of them only focus on how to import data. For example, copy data files using removable media such as ...
