The following describes the technical scheme of the embodiments of the present disclosure in detail:

in the situations of job entry, health evidence, and life insurance purchase, the user is generally required to provide a physical examination evidence to complete the transaction. Typically, the user provides a self-care paper or electronic version of the physical examination report. First, since the physical examination report is kept by the user, the physical examination report may have a problem of having been tampered with, which may result in a low reliability of the physical examination report. Secondly, the physical examination report is delivered to the user for self-keeping by the physical examination party, so that the risk of losing the physical examination report exists, and the transaction is difficult.

In view of one or more of the above problems, the present exemplary embodiment provides an information query request response method based on a blockchain network. The blockchain network-based information query request response method may be applied to the server 105, or may be applied to one or more of the terminal devices 101, 102, 103, which is not particularly limited in the present exemplary embodiment. Referring to fig. 3, the blockchain network-based information query request response method may include the following steps S310 to S340:

step S310: and carrying out encryption processing on the user information according to a preset encryption mode.

Step S320: and stamping the time stamp on the encrypted user information according to the information generation time, and uploading the time stamped user information to the blockchain network.

Step S330: and updating a database for information inquiry according to the user information in the block chain network.

Step S340: and when the information inquiry request is received and the authorization information corresponding to the information inquiry request is legal authorization information, responding to the information inquiry request according to the database.

It should be noted that, the embodiment of the present disclosure may be applied to the storage of user information (such as physical examination information), where a blockchain network may be used to store user information, and a third party or a user may query corresponding user information through a query request, so as to improve the efficiency of storage of user information and ensure the authenticity of user information obtained by the user or the third party.

Next, the above steps of the present exemplary embodiment will be described in more detail.

In step S310, the user information is encrypted according to a preset encryption scheme.

In this example embodiment, the user information may include physical examination information of the user, and may further include information of weight data of the user every day, sleep conditions of the user (such as deep sleep duration and fast eye movement sleep duration), number of steps of the user every day, and diet structure of the user, which is not limited in the embodiments of the present disclosure; the user physical examination information may include physical examination results (e.g., whether glaucoma is present, whether tumor is present, whether thrombus is present, etc.) corresponding to various types of physical examination items (e.g., an ophthalmic examination item, an ultrasonic examination item, a magnetic resonance examination item, etc.).

In the present exemplary embodiment, the blockchain technique utilized by the blockchain network is a special database technique designed based on elliptic curve digital signature algorithm (Elliptic Curve Digital Signature Algorithm, ECDSA) in cryptography to implement a decentralised Peer-to-Peer (P2P) system. From a data perspective, a blockchain is a distributed database in which the distribution is embodied not only as a distributed storage of data, but also as a distributed record of data (i.e., maintained collectively by system participants). From the viewpoint of effect, the blockchain can generate a set of data base which is recorded in time sequence, is not tamperable and is trusted, the data base is stored in a decentralization mode, and the data security can be effectively ensured. In addition, the blockchain network applied to the embodiments of the present disclosure may be composed of data blocks for storing user information, wherein the data blocks have time sequence, and the current block may track to the target block according to the hash value corresponding to each data block.

In this example embodiment, optionally, the encrypting the user information according to the preset encryption manner includes:

In this exemplary embodiment, the user information is converted into a hash value of a preset length through the hash function mapping, which may be understood that the user information is converted into a hash value of a preset length (e.g., 256 bits) through the hash algorithm; the hash algorithm is to compress any input through mapping of a hash function to generate a string of values with a certain length, namely hash values or hash values. In the embodiments of the present disclosure, the hash Algorithm may be a Message-Digest Algorithm (MD 5) or a secure hash Algorithm (Secure Hash Algorithm, SHA), and the embodiments of the present disclosure are not limited thereto. Wherein:

MD5 is a cryptographic hash function that produces a 128-bit (i.e., 16-byte) hash value that is used to ensure that the information transfer is completely consistent. Specifically, the MD5 code processes the input user information in 512-bit packets, and each packet is divided into 16 32-bit sub-packets, after a series of processing, the output of the algorithm is composed of four 32-bit packets, and after cascading the four 32-bit packets, a 128-bit hash value is generated. SHA is a family of cryptographic hash functions, including SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512, and the SHA is an algorithm for calculating a fixed-length string corresponding to a digital message.

In this example embodiment, the encryption processing on the user information according to the preset encryption manner may also be: the user information is encrypted through a hash algorithm of a preset encryption mode and then encrypted through a public key in a user key of the preset encryption mode, so that the data security is further improved through a double encryption mode, the privacy of the user can be better protected, and the use experience of the user is improved.

In this example embodiment, the method for converting the user information into the hash value with the preset length through the hash function mapping to achieve encryption of the user information may specifically be:

filling the data corresponding to the user information to enable the data length to be a preset data length (e.g. 448 module 512), and adding 64-bit data length information; further, a 256-bit cache may BE used to store intermediate and final results of the hash function, where the cache may BE represented as 8 32-bit registers (i.e., A, B, C, D, E, F, G and H), a=0x6a09e667, b=0xbb67ae85, c=0x3c6ef372, d=0xa 5453 a, e=0x510E 527F, F =0x9b05688c, g=0x1f83d9ab, h=0x5be 0CD19; further, with 256-bit cache values A, B, C, D, E, F, G and H as inputs, the cache contents are updated until 64 iterations are completed, and a hash value of a preset length (e.g., 256 bits) is output.

In this example embodiment, the manner of encrypting the user information by the public key in the user key of the preset encryption manner may specifically be:

and encrypting the user information through an encryption algorithm and a public key of a preset encryption mode. The encryption algorithm may be a symmetric encryption algorithm (symmetric key algorithms) or an asymmetric encryption algorithm (asymmetric key algorithms), and embodiments of the present disclosure are not limited thereto. Specifically, in the symmetric encryption algorithm, the key used for encryption and the key used for decryption are the same. In an asymmetric encryption algorithm, the key used for encryption and the key used for decryption are not the same.

In this example embodiment, the method may further include the steps of:

when an information inquiry request is received and is a third party inquiry request, detecting that authorization information corresponding to the information inquiry request is legal authorization information; and when the information inquiry request is received and is a user inquiry request, returning the encrypted user information corresponding to the user inquiry request. If the private key held by the user corresponds to the public key, the user information can be decrypted according to the plaintext comparison table.

The third party may be a company, insurance company, school, or the like where the user will be engaged, and embodiments of the present disclosure are not limited.

Therefore, by implementing the alternative embodiment, the probability of stealing or revealing the user information can be reduced by encrypting the user information, and the safety of the user information is ensured.

In step S320, the encrypted user information is time-stamped according to the information generation time and the time-stamped user information is uploaded to the blockchain network.

In this example embodiment, optionally, the manner of time stamping the encrypted user information according to the information generation time is:

For example, if the physical examination result includes the following information: the composition has the characteristics of glaucoma, no tumor and no thrombus, wherein the generation time of generating the examination result of the glaucoma is 2019, 1 month, 1 day, 8:00, the generation time of generating the examination result of the tumor is 2019, 1 month, 1 day, 9:00, and the generation time of generating the examination result of the thrombus is 2019, 1 month, 1 day, 10:00. Then, the examination result with glaucoma is time-stamped by 2019, 1 month, 1 day, 8:00, the examination result without tumor is time-stamped by 2019, 1 month, 1 day, 9:00, and the examination result without thrombus is time-stamped by 2019, 1 month, 1 day, 10:00. If the generation time of the user information including each physical examination result is 2019, 1 month, 1 day, 11:00, then 2019, 1 month, 1 day, 11:00 is determined as the time stamp of the user information.

It can be seen that, by implementing the alternative embodiment, the generation time of the information can be determined by adding a time stamp, so that the time corresponding to various types of information can be defined for the user, and the use experience of the user can be improved.

In this example embodiment, optionally, the method of uploading the user information after the time stamping to the blockchain network is as follows:

In this exemplary embodiment, a digital signature (also called public key digital signature or electronic signature) is a physical signature, implemented using a technology in the field of public key encryption, and is a method for authenticating digital information. A set of digital signatures typically defines two complementary operations, one for signing and the other for verification. It is also understood that a digital string cannot be counterfeited, which can be produced only by the information transmitter, can be used as a valid proof of the authenticity of the information transmitted by the information transmitter.

In this example embodiment, the manner of adding a digital signature to the user information after the time stamping and generating the data block may specifically be:

Calculating a summary corresponding to the user information with the timestamp through a hash algorithm, encrypting the summary through a private key of a sender and generating a data packet so as to finish the operation of adding a data signature to the user information; wherein a digital signature can be understood as an encrypted digest.

In this example embodiment, the verification manner of the current node corresponding to the data block may specifically be:

sequentially checking all blocks in the chain to which the current node belongs, wherein the blocks precede the data block;

if the verification result is that the chain to which the current node belongs is the same as the chain corresponding to other nodes, judging that the verification is successful; or if the verification result is that the chain to which the current node belongs is the same as the chain corresponding to other nodes with preset proportion (such as 80%), judging that the verification is successful.

It can be seen that implementing this alternative embodiment can utilize the non-tamperability of the blockchain technology to increase the true reliability of the user information, so that a third party or user can obtain the true and reliable user information.

In step S330, a database for information query is updated according to each of the user information in the blockchain network.

In this example embodiment, the database is used to store user information for a user or a third party to query.

In this example embodiment, the manner of updating the database for information query according to each piece of user information in the blockchain network may specifically be: updating a database for information inquiry in an online verification platform according to the user information in the blockchain network; the online verification platform is used for providing information query service for users or third parties. Compared with the method for acquiring the user information from the blockchain network, the method has the advantages that the speed of responding to the information query request by the database of the online verification platform is faster, and further, the use experience of a user can be improved.

In step S340, when the information inquiry request is received and the authorization information corresponding to the information inquiry request is legal authorization information, the information inquiry request is responded according to the database.

In this example embodiment, the information query request may be used to query the latest physical examination information of the target user, and may also be used to query all physical examination information about the target user, which is not limited by the embodiment of the present disclosure.

In this example embodiment, the authorization information includes an identity information field of the user, where the identity information field includes at least one of a mobile phone number, an identity card number, a name, a block address, a zip code, and a mailbox; optionally, the method further comprises the steps of:

if the consistency degree is greater than the preset degree, judging that the authorization information corresponding to the information inquiry request is legal authorization information. If the consistency degree is not greater than the preset degree, ending the flow.

In the present exemplary embodiment, the degree of coincidence and the preset degree are used to represent the same proportion of the information, for example, 80% is the same. If the preset degree indicates that 80% of the two pieces of information are identical, and the consistent degree indicates that 80% of the two pieces of information are identical, the authorization information corresponding to the information inquiry request can be judged to be legal authorization information.

In this exemplary embodiment, the authorization information may be a combination of at least two information in the identity information field, such as a mobile phone number, an identity card number, a name, a block address, a postal code, and a mailbox, for example, a mobile phone number+an identity card number+a block address. In addition, the authorization information may further include a key field of the user, where the key field may include a private key or a custom password of the user or a combination of the private key and the custom password, and embodiments of the present disclosure are not limited.

In this example embodiment, the manner of responding to the information query request according to the database may specifically be: and returning one or more pieces of user information corresponding to the information inquiry request to the client of the user or the third party.

Therefore, by implementing the alternative embodiment, the required user information can be acquired from the database through the authorization information, so that the safety of the user information is improved, and the risk of stealing the user information is reduced.

In this example embodiment, optionally, responding to the information query request according to the database includes:

In this example embodiment, the first query authority may be an authority that allows to acquire complete user information; the second query right may be a right that allows acquisition of a part of the user information. If the physical examination result in the user information includes: myopia, prolapse of lumbar intervertebral disc, glaucoma, cervical spondylosis and gynecopathy. The specific information may be myopia, lumbar disc herniation, glaucoma, and cervical spondylosis in the user information specified by the user. Because the gynecological diseases have stronger privacy than other examination results, the user can not acquire the examination results by specifying specific information, so that the privacy is protected.
