In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
As shown in fig. 1, an embodiment of the present invention provides a block chain-based personal information storage and monitoring method, where the method includes:
s101, constructing a personal information storage block chain: creating a credit granting management server, taking the credit granting management server as a core node, and taking a plurality of storage servers with personal information as accounting nodes, wherein each accounting node is interacted with the core node, and all the accounting nodes are interacted with each other to form a personal information storage block chain (as shown in fig. 2);
the credit management server is used as a core node, a plurality of storage servers are used as accounting nodes, and the storage servers are used for newly storing individuals and can be an existing personal credit investigation platform, an existing personal academic calendar information platform, an existing house property information platform, an existing medical information platform and other existing public service platforms which operate and store personal information; each accounting node reports the stored personal information to the core node; and reporting the core node when the personal information stored by each accounting node changes. And the block chain technology is adopted to ensure that the stored personal information is not randomly deleted and tampered, and the information storage safety is ensured.
Specifically, a DPOS consensus mechanism is adopted among the accounting nodes to establish a connection, wherein a change instruction of personal information stored in one accounting node is transmitted to each accounting node, and each accounting node processes the change instruction according to a preset DPOS consensus mechanism.
The DPOS is named as a deleted Proof of stamp, Chinese translation is an agency right certificate in return, the DPOS consensus algorithm converts a bookkeeper in the POS consensus algorithm into a small circle consisting of specified node numbers, and not all people can participate in bookkeeping, the circle can be 21 nodes or 101 nodes, and the node in the circle can obtain the bookkeeping right according to design. This will greatly improve the throughput of the system, since fewer nodes means that the network and nodes are controllable.
S102, constructing interaction between a personal information storage block chain and a personal information credit management terminal: interacting with each accounting node of the personal information storage area block chain and the core node through a personal information credit granting management terminal;
as shown in fig. 3, the personal information in the core node is modified, deleted, and classified by the personal information authorization management terminal; and when the stored personal information changes, the core node or the accounting node authorizes a lower authority authentication instruction of the management terminal to the personal information.
The personal information stored in the core node or the accounting node is separated, graded and encrypted or authority is set through the personal information authorization management terminal; and different personal information authorization fees are set for the personal information stored in the core node or the accounting node through the personal information authorization management terminal according to the grades. The types of personal information are various, such as identity, communication mode, family information, work background, credit information, academic information and the like, the user grades and encrypts and manages the information according to own preference, payment can be related, different authorization fees can be set according to the grading type, and free disclosure can be selected.
S103, authority authentication of the personal information data sequence is carried out: and according to the request of a third-party application program, after the authorization authentication is carried out between the credit management server and the personal information authorization management terminal, the personal information data sequence is sent to the third-party application program.
And the third-party application program sends a request for reading corresponding personal user information to the credit management server according to the user registration information, and the credit management server performs authority authentication on the personal information authorization management terminal and sends a personal information data sequence to the third-party application program after performing personal information authorization cost verification on the third-party application program.
In addition, each reading operation of the personal information data sequence by the third-party application program is reported to the credit granting management server, and the modification, deletion and copy of the personal information data sequence by the third-party application program are reported to the credit granting management server and the personal information authorization management terminal for authority authentication.
Optionally, the credit granting management server issues the personal information authorization cost to the corresponding personal account.
Optionally, when the third-party application program monitors that personal information changes or needs to be updated, the third-party application program sends a request to the trust management server and/or the corresponding storage server.
As shown in fig. 4, a personal information use block chain is formed by using the personal information authorization management terminal as a core node and all the third-party applications used as auxiliary nodes.
And the third-party application programs interact with each other, and the operation information of the personal information by the third-party application programs is sent to other third-party application programs.
And the third-party application program reports the operation information of the personal information to the personal information authorization management terminal for permission verification, and the result of the permission verification is reported to the credit granting management server.
The method has the advantages that the personal authorization management terminal is used as a core node, the third-party application program used by the user is used as an auxiliary node, and the personal information application block chain is constructed.
As shown in fig. 5, the personal information data sequence at least includes a personal information list, data transmission read-write information, personal trust key verification information, trust management key verification information, and a unique dynamic identification code.
Specifically, according to a third-party application program request, after authority authentication, the personal information data sequence of the trust management server and the personal information authorization management terminal is written into personal trust key verification information and trust management key verification information, and is written into the unique dynamic identification code generated by a random algorithm.
Optionally, the creating a trust management server further includes: defining the data file type of the personal information data sequence, defining the data transmission interface of the data file type and the analysis reading mode of the data file type.
The personal information data sequence is further refined, the encryption level of the data is improved, the data is prevented from being decoded by a third party at will, and the personal information data sequence is encrypted by referring to the technology of digital currency; the form, the rule, the algorithm of the personal information data sequence and the loading mode with the third-party application program are defined in a standardized way.
An alternative standardized way of data sequence of personal information is to use digital certificate technology. The digital certificate adopts a public key system, namely, a pair of matched keys is used for encryption and decryption. Each user sets a specific private key (private key) only known to the user, and decrypts and signs by using the private key; meanwhile, a public key (public key) is set and published by the user, and is shared by a group of users for encrypting and verifying signatures. When a secret document is transmitted, the sender encrypts data using the public key of the receiver, and the receiver decrypts the data using its own private key, so that the information can safely reach the destination without errors. By digital means it is ensured that the encryption process is an irreversible process, i.e. only decrypted with a private key. In the public key cryptosystem, one commonly used is the RSA system. The mathematical principle is to decompose a large number into the product of two prime numbers, and two different keys are used for encryption and decryption. Even if the plaintext, ciphertext, and encryption key (public key) are known, it is computationally infeasible to derive the decryption key (private key). According to the current computer technology level, the calculation time of thousands of years is needed to crack 1024 bit RSA keys. Public key technology solves the management problem of key distribution, and merchants can disclose public keys of merchants and keep private keys of merchants. The shopper may encrypt the transmitted information with a publicly known public key, securely transmit it to the merchant, and then decrypt it with its own private key.
The user can also process the information by adopting the private key of the user, and the private key is owned by the user, so that a file which cannot be generated by others is generated, and a digital signature is formed. With digital signatures, the following two points can be confirmed: the information is ensured to be sent by the self signature of the signer, and the signer cannot deny or cannot deny the information easily. The information is ensured to be not modified any more since being issued, and the issued file is a real file.
For example, network identification cards (VIEIDs) based on digital certificate technology are tools for identifying the identities of users in the world of internet information, and are used for identifying the identities of communication parties and indicating our identities or certain qualifications in network communication. The various network services and applications do not need to fill in complicated registration information, only need to input the network identity card number and the management password, and do not need to remember other various complicated account numbers and passwords. When you do not want to use a certain service, it is enough to log off directly in the network ID card management center. VIEID enables every user of the Internet to mutually trust the identity of each other, and a strict and perfect privacy management mechanism also enables personal information of the user to be prevented from being leaked. The personal information data sequence can be managed by an authorization mechanism (a trust management server) by adopting a network identity card and a digital certificate technology, but more personal information is stored compared with the network identity card, and the personal information data sequence is not only used for identity identification and authentication.
Optionally, if the third-party application copies and cracks the personal information data sequence, the unique dynamic mark code will be invalid, and at the same time, the data transmission read-write information will be activated and report the information that the unique dynamic mark code is invalid to the credit management server and/or the personal information authorization management terminal.
When the third-party application program reads the personal information data sequence and the unique dynamic coding of the personal information data sequence is wrong, the data transmission read-write information is activated and reports the information of the unique dynamic marking coding failure to the credit management server and/or the personal information authorization management terminal.

And the block chain technology is adopted to ensure that the stored personal information is not randomly deleted and tampered, and the information storage safety is ensured.
As shown in fig. 4, the chain of blocks for using personal information uses a personal information authorization management terminal as a core node, and a plurality of new third-party applications using the personal information authorization management terminal as auxiliary nodes. And the third-party application programs interact with each other, and the operation information of the personal information is sent to other third-party application programs by the third-party application programs.
