In this embodiment of the present invention, as shown in fig. 2, which is a block diagram of a structure of a data providing terminal provided in this embodiment of the present invention, the data providing terminal 110 includes:
a registration module 111, configured to perform new node registration;
an encryption module 112 for encrypting the education data and performing key management;
and an uploading module 113, configured to upload the encrypted education data to the blockchain.

In the art, registration of a blockchain network node is a matter of conventional technology and is not listed in detail herein.
In the embodiment of the present invention, the encrypting module 112, when performing encryption, includes:
running a preset key encapsulation algorithm to generate a key and a key ciphertext;
operating a preset encryption algorithm, encrypting the education data through a secret key, and generating an education data ciphertext;
and writing the address of the key ciphertext and the address of the education data ciphertext into a corresponding education data contract as the attribute information of the education data ciphertext so as to be uploaded by the uploading module.
The preset key encapsulation algorithm may be designed as needed in the art, or an algorithm in the prior art may be directly used, and different key encapsulation algorithm technologies are disclosed in papers and some patent documents published in the art, and a detailed description of the key encapsulation algorithm is not described herein.
The encryption algorithm for encrypting the educational data can be selected from the prior art, and the way of encrypting the data is mature, and is not further described here.
In the embodiment of the invention, the address of the cipher key ciphertext and the address of the education data ciphertext are written into the education data contract, so that the data acquisition end can address and find the corresponding data providing end and acquire the cipher key according to the corresponding data request to decrypt data. It is to be understood that the encryption of the education data is mainly performed for education data that needs to be kept secret, such as personal identification information, personal education qualification information, and the like, and the encryption may not be required for a part of the education data that does not need to be kept secret.
In an embodiment of the present invention, after the data providing terminal 110 receives the request information for the data obtaining terminal 120 to obtain the corresponding education data, the encryption module 112 further includes:
according to the public key in the request information issued by the data obtaining terminal 120, an encrypted file of the key is generated according to the public key and the key, so that the block chain is uploaded through the uploading module for the data obtaining terminal 120 to obtain.

and searching and acquiring corresponding education data from the block chain according to the hash value information of the education data, and if the corresponding education data cannot be searched, considering that uploading fails. The successful verification of the uploading of the education data mainly avoids misdelivery or missing of the data, and in addition, the same education data can be searched from the block chain before uploading to verify whether the same education data exist or not, so that repeated uploading is avoided.
In this embodiment of the present invention, as shown in fig. 3, which is a block diagram of a structure of a data obtaining end provided in this embodiment of the present invention, the data obtaining end 120 includes:
the transaction and download module 121, the transaction and download module 121 is used for calling an education data transaction interface to be downloaded, and performing education data transaction and download according to a preset flow;

As described above, when the data obtaining end 120 wants to obtain the education data, it may send a request for obtaining the key corresponding to the key ciphertext to the corresponding data providing end 110 according to the ciphertext address of the corresponding education data and the corresponding key ciphertext, where the request is obtained by packaging and chaining the ciphertext of the key and the public key created by the data obtaining end 120 itself, and then the encryption module of the data providing end 110 may determine the key required by the other party according to the public key and the key ciphertext and encrypt the key according to the public key, so that the key after chaining can be obtained as long as the public key is decrypted by the data obtaining end corresponding to the public key, which greatly improves the confidentiality of the education data needing to be kept secret, and prevents the education data from being maliciously obtained.
In this embodiment of the present invention, as shown in fig. 4, which is a block diagram of another structure of a data obtaining end provided in this embodiment of the present invention, the data providing end 110 further includes:
the identity information management module 114 is configured to receive identity information input by a user, where the identity information includes personal identity information or organization identity information, and upload the identity information to the block chain through the upload module after the identity information is verified; and/or
A school fee payment management module 115 for receiving the education fee transaction information inputted by the user, checking the authenticity of the education fee information, and uploading the block chain through an uploading module; and/or
The education qualification verification management module 116 is used for receiving education qualification information input by a user, wherein the education qualification information comprises personal education qualification information obtained by personal education and institution education qualification information for performing education activities in structure, and the education qualification information is verified and then uploaded to a block chain through the uploading module; and/or
The credit information management module 117 is configured to receive a preset credit conversion protocol, generate a credit conversion intelligent contract according to the credit conversion protocol, and upload the credit conversion intelligent contract to the block chain through the upload module; and when receiving the credit information input by the user, acquiring the credit intelligent contract for credit conversion and uploading the updated credit information to the block chain.
Wherein, the identity information management module 114 can self-certify the qualifications online by students and job seekers by using the block chain while maintaining control over personal data storage and management. In the prior art, for example, in a large organization, students need to perform identity authentication with different departments of the organization at regular intervals, under the condition, each department of the organization can collect student data for the students, or the organization adopts a single sign-on mode to ensure that all parties in the organization can use a shared copy of the student data; in both modes, tens or even hundreds of people can access the personal information of the student. To secure these data requires managing the access rights of all these people and ensuring that their devices are also secure and hacking-proof, which is a daunting task. In this embodiment of the invention, only a few people (i.e., the parties responsible for verifying the identity of the student) have access to this data in blockchain mode. In addition to this, it is held in the hands of students, which means that the institution no longer needs to manage access rights to complex systems, only needs to ensure the security of the device or network responsible for checking the initial authentication, which will save a lot of resources for strengthening the network to prevent data leakage, training data protection for staff, and strengthening management access rights. Accordingly, the identity information belongs to the aforementioned educational data needing security, and the processes of encrypting, uploading, acquiring, and decrypting can be referred to above.
The method of verifying and uploading the education expenses by the academic expense payment management module 115 can record the details of each transaction with a student, a huge block link data set is used for containing all histories of each transaction, data are changed into protected virtual assets, and each transaction and data are ensured to have a right-confirming certificate, so that each transaction has credibility, safety and non-tamper-proof property, the authenticity and validity of the data are ensured, the wind control module is provided, the fraud risk is effectively reduced, and parents can be helped to know and make intelligent decisions according to the charges of education institutions.
The education qualification verification management module 116 verifies the education qualification information and uploads the verification result to the block chain through the upload module, so that the education certification document and the education qualification which can be performed of an individual or an organization can be truly and effectively proved and cannot be modified. Specifically, for example, in the prior art, it is not a simple matter to verify the credentials of the entire educational system of some educational institution; for example, in europe, there are hundreds of certification pathways through public and private institutions, and thus employers need to verify not only the certificate issuer, but also the qualifications of the institution issuing the certificate; currently, the verification process involves the consulting authority itself, and in turn, determining the quality of the certificate that the authority claims to possess, confirming this issuance to the certification authority itself, and verifying with the governing authority to determine whether the certification authority has authorization to issue the corresponding certificate; this is a very time consuming technical process, requiring certified specialists to manage, requiring multiple departments or processes to coordinate the management of the process. However, the embodiment of the present invention provides a more efficient alternative by combining with the blockchain, a fully automated process can visualize the certification chain and verify that the certificate is actually issued depending on the characteristics of the blockchain, and it is very critical that this process is continuously effective for each step of the certification chain.
The credit information management module 117 generates an intelligent contract according to the credit conversion protocol and links the intelligent contract so that different education institutions complying with the credit conversion protocol do not reasonably admit the revised credit of the student. In particular, score conversion is a delicate process, and students often feel that they are disadvantaged when they find that they must repeat a learning session to meet the requirements of a new institution. Currently, credit conversion relies on institutions agreeing through negotiations to admit each other's credits under certain conditions-but students often report that these agreements are not admitted; and by using a block chain, the protocols can be written into intelligent contracts, and the credit score is automatically converted according to the conditions of the contracts, so that the problem is solved.
According to the big data sharing system based on the block chain, disclosed by the embodiment of the invention, the education data are subjected to chain linking management by utilizing the characteristics of the block chain, so that the personal education data can be rapidly verified and mastered, the personal education data are prevented from being abused, the qualification verification of an education institution can be more accurate and real, the education structure is prevented from being forged, and the judgment of students or parents is facilitated.
