Data table storage method, data table modification method, data table query method and data table statistical method

Abstract

The present invention relates to the field of data control, and particularly to a data table storage method, a data table modification method, a data query method and a data statistical method. The data table storage method comprises: splitting a data table according to the type of the data table such that the split data tables cannot express the meaning of the original data table; and storing the split data tables to predetermined positions. According to the data table storage method provided by the present invention, through splitting fields in the original data table, a plurality of new data tables are generated, so that a single new data table cannot express the meaning of the original data table; and the splitting manner of each kind of the fields is unique, so that even if a new data table is acquired by others, the original data table cannot be restored according to the new data table, and thus content in the original data table will not be revealed, thereby ensuring security of the content in the data table and thus solving deficiencies in the prior art.

Description

technical field [0001] The invention relates to the field of data control, in particular to a data table storage method, a data table modification method, a data query method and a data statistics method. Background technique [0002] With the continuous development of Internet technology, products based on various cloud architectures emerge in an endless stream. The carrier of cloud storage technology is cloud system. Specifically, cloud system includes public cloud and private cloud. Private clouds are safe but not easy to use on a large scale. The security of public clouds is actually and psychologically weaker, but various computing resources, storage resources, and bandwidth resources are relatively better. Therefore, many users are faced with the dilemma of storing their data in a public network and facing security issues. [0003] For example, many of the current video, audio, text, database and other data are private data of individuals or public institutions. If th...

Problems solved by technology

[0003] For example, many of the current video, audio, text, database and other data are private data of individuals or public institutions. If they are placed in a single service provider, no matter how the provider encrypts them, users will think that they are out of their control. , resulting in a sense of psychological insecurity. At present, the main technology used in the world is to store and encrypt user data through its own encryption means, and store them separately in its own system.
