Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] It can be understood that the terms "first", "second" and the like used in the present invention may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first encryption algorithm could be termed a second encryption algorithm, and, similarly, a second encryption algorithm could be termed a first encryption algorithm, without departing from the scope of the present invention. Both the first encryption algorithm and the second encryption algorithm are encryptio...

Abstract

The invention relates to a data storage method and device, a storage medium and computer equipment. The method comprises the following steps: receiving original data which comprises timestamp; carrying out iterative computation by taking the timestamp as a random seed of a preset random algorithm to generate a random secret key; encrypting portions, which correspond to sensitive field names in a preset sensitive field name database, in the original data by a preset first encryption algorithm according to the random secret key; carrying out transformation treatment on the encrypted original data to generate replacement data; and storing the random secret key and the replacement data to a database table. By the data storage method and device, the storage medium and the computer equipment, safety of data storage is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data storage method, device, storage medium and computer equipment, and a data query method, device, storage medium and computer equipment. Background technique [0002] A database table is a collection of two-dimensional arrays, consisting of vertical columns and horizontal rows. A column is composed of similar information, each column is also called a field, and the title of each column is called a field name; a row includes several columns of information items, and a row of data is called a or a record. When the data to be stored is sensitive, the data is usually encrypted and then stored in the database table. [0003] However, in the traditional data storage method, since the encrypted content of the same data is consistent, the original value of the data may still be deduced by the cracker after the data is encrypted, which makes the traditional data storage me...
