Problems solved by technology

[0003] According to the security characteristics of the blockchain, no one can obtain permission to tamper with the data stored in the blockchain, nor can it be deleted or forged, which makes the blockchain an ideal, safe, Open data storage technology, but it also makes it difficult to implement data supervision, unable to trace the source of bad data, unable to delete bad data

Embodiment Construction

[0027] This embodiment provides a supervised method for enclosing tamper-proof images in the block chain. The flow chart of the method combines figure 1 and figure 2 The specific instructions are as follows:

[0028] Step S201, the user uploads the user image to the data management center;

[0029] Wherein, the data management center is preset with image checking and filtering functions.

[0030] Step S202, the data management center checks and filters the image uploaded by the user, and generates an access link of the image;

[0031] Wherein, the data management center generates a verification hash value for legal data, and returns the hash value to the user as a part of the access link;

[0032] Wherein, the data management center calculates the legal data uploaded by the user and the hash value of an optional special key;

[0033] Wherein, the data management center returns fixed error information to illegal data.

[0034] Step S203, the user obtains the access link o...

Abstract

The invention discloses a method for supervising enclosing non-tamperable images in the block chain. By uploading user images to the data management center, the data management center will supervise the image data and return an access link to the legal data. The user will The access link is used as instruction data to issue an instruction to access the blockchain. After receiving the instruction, the blockchain accesses the data management center according to the access link in the instruction data to obtain complete user image data. After enclosing the blockchain, the unique access hash value of its image data in the blockchain is returned to the user, thus realizing the supervised encapsulation of tamper-proof images in the blockchain.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a method for encapsulating tamper-proof images in a block chain under supervision. Background technique [0002] Blockchain technology is a distributed ledger technology that has emerged in recent years. It is a collection of computer information technology applications such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. From the data level, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order. It is characterized by decentralization, openness and transparency, unchangeable, and unforgeable. Blockchain technology has broad application prospects in product authenticity and traceability systems. [0003] According to the security characteristics of the blockchain, no one can obtain permission to tamper with the data stored in the blockc...
