Abstract

The invention is suitable for the technical field of computers, and particularly relates to a intelligent cloud data safety protection system and method based on a block chain. The system comprises a random number generation module which is used for randomly collecting a group of source images, carrying out the image analysis of the source images, and obtaining a random number group; a ciphertext query module is used for querying a preset ciphertext database according to the random number group to obtain an encrypted ciphertext data block group; a data reorganization module is used for recompiling the cloud data according to the encrypted ciphertext data block group to obtain reorganized cloud data; a data broadcasting module is used for broadcasting the recombined cloud data to the block chain and independently storing the encrypted ciphertext data block group. According to the method and the device, the encrypted ciphertext for encryption is generated in a true random mode to encrypt the cloud data needing to be protected, so that the specific content of the cloud data is changed, the encrypted ciphertext is independently stored, the cloud data can be decrypted by using the encrypted ciphertext, and the transportation safety is improved.

Description

technical field

[0001] The invention belongs to the field of computer technology, and in particular relates to a smart cloud data security protection system and method based on blockchain. Background technique

[0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects.

[0003] In the current data protection storage system, encryption is mainly used for protection. In the encryption method, it is mainly divided into symmetric encryption and asymmetric encryption. Symmetric encryption means that encryption and decryption use the same key, and asymmetric encryption means...

Embodiment Construction

[0060] 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.

[0061] It can be understood that the terms "first", "second" and the like used in the present application may be used to describe various elements herein, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first xx script could be termed a second xx script, and, similarly, a second xx script could be termed a first xx script, without departing from the scope of the present application.
