The target website may be a website corresponding to the target information query mechanism. In this case, after receiving an authorization request sent by the first user to authorize the second user to perform object information query, the node may screen out target object information matching the first user information from object information of each user stored in the storage area. The storage area may be a local storage area of a node, or a blockchain maintained by a blockchain network. The target website may be a website including object information, and for example, assuming that the object information is personal education experience information, the target website may be a learning website or the like; assuming that the object information is marital information, the target website may be a website corresponding to a marital information inquiry mechanism.
In another embodiment, the storage area includes a blockchain maintained by a blockchain network, and before the node acquires target object information matching the first user information from the storage area, an object information upload request submitted by the first user may be further received, where the object information upload request includes the object information of the first user and the user information of the first user. Further, the node may perform consensus verification on the object information of the first user and the user information of the first user, and write the object information of the first user and the user information of the first user into the block chain if the consensus verification passes. Further, after receiving an authorization request sent by a first user for authorizing a second user to perform object information query, the node may obtain target object information matched with the first user information from the blockchain. By adopting the mode, the credibility of the acquired object information can be improved by utilizing the characteristics that the block chain is not falsifiable and not faked.
Or, after receiving the object information uploading request submitted by the first user, the node may write the object information of the first user and the user information of the first user into the blockchain, and may also store the object information of the first user and the user information of the first user in the local storage area. The present invention is not particularly limited in this regard.

In one embodiment, before the first user submits an authorization request for authorizing the second user to perform object information query to a node of the blockchain network, the own user information (i.e., the first user information) may be digitally signed based on an own private key (hereinafter referred to as a first private key). Further, after receiving the authorization request, the blockchain network may verify the digital signature based on a public key of the first user (hereinafter referred to as a first public key), and if the verification is passed, trigger execution of the step of acquiring the target object information matched with the first user information from the storage area. Or if the verification fails, outputting prompt information to the first user for prompting that the digital signature of the first user is wrong.
In one embodiment, before the node receives the authorization request, the first user may upload its public key to the node, and store the public key in a storage area (e.g., a local storage area, a blockchain maintained by a blockchain network, etc.) by the node. Further, after the node sends the public key of the first user (hereinafter referred to as the first public key) to the storage area, the node may also generate a first sub-public key for the first public key based on a preset public key generation algorithm, and set the first valid time and the first setting time for the first sub-public key. In this case, after the block chain network receives the authorization request, it may be determined that the first sub public key is valid before the first valid time elapses from the first set time, and then the digital signature is verified by using the first sub public key.
S503: and acquiring a public key of the second user based on the second user information, and encrypting the target object information through the public key of the second user.
S504: and generating a two-dimensional code according to the encrypted target object information, and sending the two-dimensional code to a second user.
In one embodiment, the first user and the second user may publish their public keys in the blockchain in advance, and the node may store the public keys corresponding to the first user and the second user in association with the user information corresponding to the first user and the second user. In this case, after the node acquires the target object information, the public key of the second user may be acquired based on the second user information carried in the authorization request, and the target object information may be encrypted by the public key of the second user. And further, generating a two-dimensional code according to the encrypted target object information, and sending the two-dimensional code to a second user. And the second user can conveniently recognize the two-dimension code after receiving the two-dimension code and decrypt the two-dimension code information based on the private key of the second user to obtain the target object information of the first user.
In one embodiment, before the node receives the authorization request, the second user may upload its public key to the node, and store the public key in a storage area (e.g., a local storage area, a blockchain maintained by a blockchain network, etc.) by the node. Further, after storing the public key of the second user (hereinafter referred to as a second public key) in the storage area, the node may further generate a second sub-public key for the second public key based on a preset public key generation algorithm, and set a second valid time and a second set time for the second public key. In this case, the specific implementation manner in which the node obtains the public key of the second user based on the second user information and encrypts the target object information through the public key of the second user may be: and before the second valid time is elapsed from the second set time, the node determines that the second sub public key is valid. Further, under the condition that the second sub public key is determined to be valid, the second sub public key is obtained, and the target object information is encrypted through the second sub public key.
In another embodiment, if the node determines that the second sub public key is invalid, a third sub public key may be generated for the second public key based on the preset public key generation algorithm, a third valid time and a third set time may be set for the third sub public key, and then the currently generated third sub public key is used to encrypt the target object information.
In an embodiment, the target object information includes target marriage information, after the node acquires the target object information matched with the first user information from the storage area, whether the marriage state of the first user is in an unmarried state or not can be detected based on the target marriage information, if the first user is determined to be in the unmarried state based on the target marriage information, the affinity between the first user and the second user is inquired based on the first user information and the second user information, and if the affinity is detected to be the affinity, the affinity warning information is generated. Further, the encrypted two-dimensional code and the close-up warning information can be sent to the second user.
Wherein, the close relation mainly refers to that direct and collateral relatives within the third generation are close relatives, parents brothers and sisters, exterior hall relatives and the like, and according to the view point of related genetics, the incidence of offspring born by close marriage is obviously higher than that of offspring born by non-close breeding in the aspect of some genetic diseases, thereby influencing the quality of human beings and the like and bringing a series of social problems. Therefore, when the node detects that the close relationship exists between the first user and the user, the node can send close warning information to the first user and/or the second user to prompt that the close relationship exists between the first user and the second user, and the situation that the two users unknowingly join a marriage student is prevented from causing irreparable loss.
In another embodiment, the target object information may include target marital information, and if the node determines that the first user is in an unmarried state based on the target marital information, genetic medical history information corresponding to each of the first user and the second user is queried based on the first user information and the second user information, and further, the encrypted two-dimensional code and the encrypted genetic medical history information may be sent to the second user. The genetic medical history information can refer to the genetic medical history of the family where the first user and the second user are located, and can also refer to easily inherited disease information of the first user and the second user. Related diseases such as vision problems, skin problems, migraine, mood problems, intestinal problems, etc. are all diseases that are easily inherited.
In an embodiment, the authorization request further includes authorization right information, and a specific implementation manner of the node acquiring, from the storage area, the target object information matched with the first user information may be: and acquiring object information corresponding to the first user information from the storage area, and screening target object information from the object information corresponding to the first user information based on the indication of the authorization authority information.
Wherein the authorization authority information is used for limiting the scope of querying the object information of the first user. Illustratively, the object information includes marriage information, and the query range indicated by the authorization authority information is the marriage state, assuming that the marriage information of the first user includes the marriage state of the first user, "not married," historical marriage times "3 times," and the existence duration of each marriage. In this case, the node may select target marital information, that is, the marital status "not married", from the marital information corresponding to the first user information based on the instruction of the authorization authority information, and may not acquire the remaining historical marital times "3 times" and the remaining time of each marital. By adopting the mode, the personalized requirements of the first user can be met, and the target marital information of the first user can be acquired more intelligently.
In the embodiment of the present invention, a node of a block chain network may receive an authorization request submitted by a first user and used for authorizing a second user to perform object information query, where the authorization request includes first user information of the first user and second user information of the second user. Further, the node may acquire target object information matched with the first user information from the storage area, acquire a public key of a second user based on the second user information, encrypt the target object information through the public key of the second user, generate a two-dimensional code according to the encrypted target object information, and send the two-dimensional code to the second user, so that the second user can recognize the two-dimensional code after receiving the two-dimensional code, and decrypt the two-dimensional code information based on a private key of the second user to obtain the target object information of the first user. By adopting the mode, the second user can quickly obtain the target object information of the first user, and the query efficiency of the object information is improved.

The target storage area may include a local storage area of the third platform, a database of a server corresponding to the third platform, or an object information query mechanism having a communication connection with the third platform. Or, in an embodiment, when the server corresponding to the third platform is a node in a blockchain network, the target storage area may also be a blockchain maintained by the blockchain network.
In one embodiment, after the third platform receives an authorization request sent by the first user for authorizing the second user to perform object information query, the third platform may query target object information matched with the first user information from a pre-connected object information query mechanism based on the first user information.
In another embodiment, before the third platform acquires the target object information matched with the first user information from the target storage area, the third platform may further crawl user information and object information of each user from the target website based on object data crawling rules configured for the target website, and store the user information and the object information of each user in the storage area in an associated manner.

For a specific implementation manner of the node obtaining the two-dimensional code including the target object information of the first user based on the authorization request, refer to steps S501 to S504 in the foregoing embodiment, which is not described herein again.
S602: and identifying the two-dimension code to obtain two-dimension code information corresponding to the two-dimension code.
S603: and decrypting the two-dimensional code information based on the private key of the second user to obtain target object information.
S604: and outputting the target object information in the display interface.
In an embodiment, after the terminal device obtains the two-dimensional code, a second user may identify the two-dimensional code through the terminal device to obtain two-dimensional code information corresponding to the two-dimensional code. Further, the second user can input a private key of the second user to decrypt the two-dimensional code information, and target object information of the first user is obtained. When the detection terminal device detects that the decryption is successful, the target object information can be output in the display interface, so that the user can conveniently and quickly check the target object information of the first user.
In an embodiment, when the third platform or the node of the block network generates the two-dimensional code, an effective time threshold or an effective time threshold of the two-dimensional code may also be set, where both the effective time threshold and the effective time threshold may be preset by a developer according to experimental measurement and calculation data. In an embodiment, when the third platform or the node of the block network generates the two-dimensional code, an effective number threshold is set for the two-dimensional code, when the terminal device identifies the two-dimensional code, a historical identification number of the two-dimensional code may also be obtained, and if the historical identification number is greater than the effective number threshold, two-dimensional code failure information is output to prompt that the identification number of the two-dimensional code reaches an upper limit. If the historical identification frequency is less than or equal to the effective frequency threshold, the two-dimensional code can be normally identified to obtain the two-dimensional code information, and further, the identification frequency of the two-dimensional code can be accumulated once (namely, the historical identification frequency is + 1).
In another embodiment, when the third platform or the node of the block network generates the two-dimensional code, the valid duration threshold and the setting time may be set for the two-dimensional code. When the terminal equipment identifies the two-dimension code, the time difference between the current system time and the set time can be used, if the time difference is greater than the effective duration threshold, two-dimension code failure information is output and used for prompting that the time is too long and the two-dimension code fails; if the time difference is smaller than or equal to the effective duration threshold, the two-dimensional code can be normally identified, and two-dimensional code information is obtained.
