Problems solved by technology

[0004] However, the existing security chip storage schemes have many requirements for hardware, so the practical application is limited; and there are many schemes that use algorithms to scramble data and then store them, but the algorithms used are relatively complex and difficult to operate

Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0051] figure 1 It is a schematic flowchart of a data storage method provided by an embodiment of the present invention. like figure 1 As shown, the method includes the following steps:

[0052] Step 101, filling random data in the storage space. Wherein, the storage space is pre-applied.

[0053] It should be noted that before storing data, first apply for a piece of space as a storage space, and then fill the storage space with random data.

[0054] Specifically, filling random data in the storage space in step 101 may be implemented by a data storage device; the information processing device may be a server capable of installing application programs.

[0055] Step 102: Select a target storage space among storage spaces according to a predetermined cycle direction.

Abstract

Examples of the present invention provide a data storage method, including: fill in random data in the storage space; select the target storage space in the storage space according to the scheduled circular direction; delete the random data in the target storage space, and store the storage in turn to be stored in order to store storage in turn to be stored in order. data. Examples of the present invention also provide a data storage device at the same time.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data storage method and device. Background technique [0002] In data storage, if some key and sensitive confidential data are not handled properly when stored in the storage medium, it is easy to cause the risk of confidential data leakage. For example, when the confidential data is stored according to continuous storage addresses, after repeated read and write operations It is easy for the tracked person to find the storage characteristics, so that they can copy the confidential data, resulting in the leakage of confidential data. [0003] Therefore, in actual operation, it is often necessary to process the storage of confidential data, for example, storing confidential data in an isolated physical space, such as a security chip; or using algorithms to scramble the data and store the disturbed data in different places . [0004] However, the existing security chip storage scheme...
