First, several terms referred to in the present application will be explained.

The block chain system: refers to a system that employs block chain Technology (Blockchain Technology) to store data. The block chain technology is also called as distributed book technology, is an internet database technology, and is characterized in that centralization and public transparency are achieved, and everyone can participate in database recording. Blockchain technology may be a distributed infrastructure and computing approach that utilizes blockchain data structures to authenticate and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secures data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data. The data stored in the blockchain system has high stability and reliability, and the blockchain system is a non-tampered and trusted database. Therefore, compared with the traditional mode of manually recording the access information, the block chain system is adopted to store the access information, and the safety and the reliability of the access information are improved.

The blockchain system can comprise a plurality of node devices, and data can be shared between the node devices. Each node device can receive input information during normal operation, and maintain shared data in the blockchain system based on the received input information. In order to ensure information intercommunication in the blockchain system, information connection can exist between each node device in the blockchain system, and information transmission can be carried out between the node devices through the information connection. For example, when any node device in the blockchain system receives input information, other node devices in the blockchain system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored in all the node devices in the blockchain system are consistent.

Each node device in the blockchain system has a node device identifier corresponding thereto, and each node device in the blockchain system can store node device identifiers of other node devices in the blockchain system, so that the generated block is broadcast to other node devices in the blockchain system according to the node device identifiers of the other node devices in the subsequent process. Each node device may maintain a node device identifier list as shown in table 1, and store the node device name and the node device identifier in the node device identifier list correspondingly. The node device identifier may be an IP (internet protocol) address or any other information that can be used to identify the node device, and table 1 only illustrates the IP address as an example.

TABLE 1

Node device name	Node device identification
		Node device 1	117.114.151.174
Node device 2	117.116.189.145
		…	…
Node device N	119.123.789.258

Each node device in the blockchain system is configured with an identical blockchain. A block chain is composed of a plurality of blocks, fig. 1 is a schematic diagram of a plurality of blocks in the block chain provided in the embodiment of the present application, referring to fig. 1, a starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

Block height: the number of blocks linked to the main chain, i.e. the number of blocks connected to the block chain.

A consensus algorithm: the method refers to a mathematical algorithm for establishing trust and obtaining rights and interests among different node devices in a block chain system. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of the special node devices, and if a plurality of node devices with irrelevant benefits can achieve the consensus, all the node devices in the system can also achieve the consensus.

And (3) property management: the method is entrusted by property owners, and maintenance, repair and treatment are carried out on management projects of property buildings, equipment, municipal utilities, greening, sanitation, traffic, public security, environmental appearance and the like according to property management entrustment contracts, and comprehensive paid services are provided for property owners and users.

Fig. 2 is a schematic diagram illustrating an implementation environment of a block chain-based access information processing method according to an embodiment of the present application. The implementation environment may include: the blockchain system 21 includes a plurality of node devices 210 in the blockchain system 21, and any node device 210 may execute one or more steps of the access information processing method based on the blockchain provided in the embodiment of the present application.

The plurality of node devices 210 in the blockchain system 21 may be configured with an access blockchain for storing access information, wherein the access information may include reservation information, access registration information, access progress information, access end information, and the like. The access block chain is composed of a plurality of blocks, and the adjacent blocks have an incidence relation, so that the information in any block can be detected by the next block when being tampered, the access information can be prevented from being tampered, and the safety and the reliability of the access information processing process are ensured. In an actual application scenario, the node device 210 configured with the access block chain may be a node device corresponding to different departments or different objects, for example, as shown in fig. 3, the node device 210 configured with the access block chain may be a terminal of an accessed object, a server of a property, a monitoring device terminal, or the like.

The node device 210 refers to a computer device, and the computer device may be a terminal or a server, which is not limited in this embodiment of the present application.

It will be understood by those skilled in the art that the above-described blockchain system 21 is merely exemplary, and that other existing or future blockchain systems, as may be suitable for use in the present application, are also included within the scope of the present application and are hereby incorporated by reference.

Based on the implementation environment shown in fig. 2, an embodiment of the present application provides a method for processing access information based on a blockchain, where the method may be applied to any node device in a blockchain system. Fig. 4 is a flowchart of a method for processing access information based on a block chain according to an embodiment of the present application, and as shown in fig. 4, the method according to the embodiment of the present application may include the following steps:

401. the first node device receives the reservation information and stores the reservation information in the blockchain system when the reservation information is commonly identified.

The reservation information refers to information for reserving access in advance, and the reservation information includes, but is not limited to, a reservation time range, identification information of the first object, identification information of the second object, an access cause, and the like. Wherein the reserved time range is used for indicating a time range for the first object to access; the first object refers to the accessed object and the second object refers to the accessed object. The identification information refers to information for identifying identity, and the identification information of the first object may refer to information such as name, identity document number, face image, and the like of the first object; the identification information of the second object may refer to information such as a living address, a name, an identification document number, etc. of the second object.

In one possible implementation, the generation of the subscription information includes, but is not limited to, the following two:

the first method is as follows: the reservation information is generated by the second object.

In this manner, the reservation information may be sent by the terminal of the second object to the blockchain system. The process of sending the reservation information to the blockchain system by the terminal of the second object may be: and after the second object logs in the application program or the webpage and fills in the reservation information, the terminal of the second object can acquire the reservation information and then sends the reservation information to the block chain system. It should be noted that the terminal of the second object may be a node device in the blockchain system.

When the subscription information is generated by the second object, the second object grants the first object access by default. That is, the reservation information generated by the second object includes information that the second object authorizes the first object to access. For example, fig. 5 is a schematic diagram of reservation information generated by a second object according to an embodiment of the present application, where the reservation information generated by the second object includes identification information of a first object, identification information of a second object, information of authorized access, and a reservation time range.

The second method comprises the following steps: the reservation information is generated by the first object.

In this manner, the reservation information may be sent by the terminal of the first object to the blockchain system. The process of sending the reservation information to the blockchain system by the terminal of the first object may be: the terminal of the first object is provided with an application program or a webpage capable of making a reservation, and after the first object logs in the application program or the webpage and fills in reservation information, the terminal of the first object can obtain the reservation information and then sends the reservation information to the block chain system.

When the reservation information is generated by the first object, it is not possible to confirm whether the second object authorizes the first object to access. That is, the reservation information generated by the first object does not include information on whether the second object authorizes the first object to access. For example, fig. 6 is a schematic diagram of reservation information generated by a first object, where only identification information of the first object, identification information of a second object, and a reservation time range are included in the reservation information generated by the first object according to an embodiment of the present application.

The first node device receives the reservation information whether the reservation information is generated by the second object or the first object. In one possible implementation manner, the manner in which the first node device receives the reservation information may be: after a terminal of a first object or a terminal of a second object sends reservation information to a blockchain system, a management node device in the blockchain system receives the reservation information; the management node equipment inquires an access block chain for storing the access information in the block chain system based on the reservation information; the management node equipment sends the reservation information to the first node equipment configured with the access block chain; the first node device receives reservation information. In this embodiment of the application, a node device that receives reservation information sent by a management node device is taken as a first node device, and in an actual application scenario, the first node device may refer to a server of a property, and the like.

In a possible implementation manner, in order to ensure information security in the process of sending the reservation information to the first node device by the management node device, before the management node device sends the reservation information to any first node device, the management node device may encrypt the reservation information according to a public key of any first node device, and then send the obtained encrypted information to any first node device. After receiving the encrypted information, the any first node device can decrypt the encrypted information according to the private key to obtain the reservation information. The method can effectively avoid the alteration of the reservation information and improve the transmission safety of the reservation information.

The first node device may initiate a consensus process for the reservation information in the blockchain system after receiving the reservation information, and when the reservation information is agreed, the first node device stores the reservation information in the blockchain system. The storage process can be divided into the following two steps:

the method comprises the following steps: the first node device generates a target block based on the reservation information.

In the block chain technique, data may be stored in blocks in the form of electronic records, and in this embodiment, when a packing condition is satisfied, the first node device may pack reservation information to generate a target block. The meeting of the packing condition may be to meet a time interval required for packing data or to meet a data quantity required for packing data, which is not limited in the embodiment of the present application.

In one possible implementation, the process of the first node device generating the target block may be as follows:

when receiving the reservation information, the first node equipment verifies the reservation information, and after the verification is completed, the first node equipment takes the reservation information as input information, stores the input information into a memory pool, and updates a hash tree for recording the input information; and then, updating the updating time stamp to the time when new input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can satisfy the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; the prev _ hash is a block head characteristic value of a parent block of the target block, and the parent block of the target block is a block with the largest block height on the current access block chain; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Thus, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and a block header and a block main body are generated to obtain the target block.

It should be noted that the above description of the target block generation process is only an exemplary description of one block generation method, and the embodiment of the present application does not limit which block generation method is specifically adopted.

Step two: the first node device adds the target block to a chain of visited blocks in the blockchain system based on a consensus mechanism.

The blockchain system may perform consensus on the target block to determine whether the data in the target block is accurate, i.e., to verify the data in the target block. In a possible implementation manner, after the first node device generates the target block, the first node device may send the target block to other node devices respectively according to node device identifiers of other node devices in the blockchain system, the other node devices may verify the target block, and broadcast verification results in the blockchain system respectively, and when the number of node devices whose verification results are passed in the blockchain system is greater than a reference ratio or greater than a reference number, the first node device may determine that the target block commonly identifies and passes, and then add the target block to an access block chain in the blockchain system. The reference proportion refers to a proportion that the number of the node devices passing the verification result accounts for the number of all the node devices in the block chain system, and the reference proportion may be set empirically or may be freely adjusted according to an application scenario, which is not limited in the embodiment of the present application. For example, the reference ratio may be set to 1/3 or the like. Likewise, the reference number may be set empirically, or may be freely adjusted according to the total number of all node devices in the blockchain system, for example, the reference number may be set to 100, and so on. The consensus process described above may be implemented based on a consensus mechanism, which may be, for example, a workload proving mechanism, a rights proving mechanism, or the like. It should be noted that the above-mentioned consensus process is only an exemplary description, and the embodiments of the present application do not limit this.

Through the first step and the second step, the first node device can store the received reservation information on the access block chain, and synchronize the reservation information to each node device configured with the access block chain.

Each time new reservation information is received, the first node device may store the new reservation information on the access block chain through the above-described first and second steps. The stored reservation information on the access block chain is not allowed to be tampered, and only a new block stored with new reservation information is allowed to be added to the access block chain. The block characteristic value of the new block is related to the block characteristic value of the previous block, so that the purpose of connecting the blocks adjacent to each other in series in the block chain is realized, and the tampering of any information in the access block chain can be detected by tracing the block characteristic value stored in the next block. The reservation information is stored in the access block chain, so that the reservation information is prevented from being lost or tampered, the safety and reliability of the reservation information are guaranteed, the possibility of maliciously modifying the reservation information is greatly reduced, the transparency and the trust degree of the reservation information are improved, and the follow-up operations such as checking the access object according to the reservation information in the block chain system are facilitated.

It should be noted that, in the case where the reservation information is generated by the first object, since the reservation information does not include information on whether the second object authorizes the first object to access, after the reservation information generated by the first object is stored in the blockchain system, the first node apparatus needs to transmit the reservation information to the terminal of the second object to acquire information on whether the second object authorizes the first object to access. The process may include the following three steps:

the method comprises the following steps: the first node device sends the reservation information to the terminal of the second object.

After the first node equipment stores the reservation information in the block chain system, according to the identification information of the second object in the reservation information, the terminal of the second object is determined, the reservation information is sent to the terminal of the second object, and the terminal of the second object displays the reservation information, so that the second object judges whether the first object is authorized to access according to the displayed reservation information.

The embodiment of the present application does not limit the manner in which the second object determines whether to authorize the access of the first object according to the displayed reservation information. For example, the second object determines whether the identity of the first object in the displayed reservation information is trusted, and when it is determined that the identity of the first object is trusted, the first object is authorized to access; access by the first object is not authorized when the identity of the first object is determined to be untrusted. For another example, the second object judges whether the displayed reservation time range in the reservation information is proper, and when the reservation time range is determined to be proper, the first object is authorized to access; when the reserved time range is determined to be inappropriate, the first object is not authorized to access.

After the second object determines whether the first object is authorized to access, the terminal of the second object may obtain information whether the second object is authorized to access by the first object. And then the terminal of the second object takes the acquired information whether the second object authorizes the first object to access as the form information of the second object, and sends the reservation information carrying the form information to the block chain system.

In a possible implementation manner, the terminal of the second object is a node device in the blockchain system, and before sending the reservation information carrying the table information, the terminal of the second object may encrypt the reservation information carrying the table information by using a private key, and then send the encrypted reservation information carrying the table information to the blockchain system.

Step two: and the first node equipment receives reservation information carrying the form information fed back by the terminal of the second object.

After the terminal of the second object sends the reservation information carrying the table information to the blockchain system, the first node device in the blockchain system may receive the reservation information carrying the table information. Wherein the form information is used for indicating whether the second object authorizes the first object to access. That is, the meaning indicated by the formal information may or may not grant access to the first object for the second object.

In a possible implementation manner, when the first node device receives the encrypted reservation information carrying the table information, the public key of the terminal of the second object may be used to decrypt the encrypted reservation information carrying the table information, and if the decryption is successful, the reservation information carrying the table information is obtained, which indicates that the reservation information carrying the table information is really sent by the terminal of the second object; if the decryption is unsuccessful, it indicates that the reservation information carrying the form information is not sent by the terminal of the second object, and the received information is not trusted. By the method, the reservation information carrying the form information can be effectively prevented from being tampered.

Step three: when the reservation information carrying the table information passes the identification, the first node equipment stores the reservation information carrying the table information in the block chain system.

The storage process may refer to the above process for storing the reservation information, and is not described herein again.

Through the above steps one to three, it is equivalent to updating the reservation information generated by the first object and already stored in the blockchain system, and updating the reservation information not including the information whether the second object authorizes the first object to access into the reservation information carrying the formal information of the second object. As shown in fig. 6, the reservation information carrying the table information includes identification information of the first object, identification information of the second object, table information of the second object, and a reservation time range. And the second object is used for accessing the second object according to the table information of the second object.

Through the above process, whether the second object is authorized to access the first object or not can be judged according to the reservation information which is stored in the block chain system and generated by the second object or the reservation information which is stored in the block chain system and carries the table information.

402. The second node device acquires identification information of the first object.

The reservation information has been stored in the blockchain system, via step 401. When the first object reaches the target area, the second node device acquires the identification information of the first object so as to inquire whether reservation information corresponding to the first object exists in the block chain system according to the identification information of the first object.

The target area may refer to any portal of the area where the accessed object is located, for example, may refer to any portal of a residential cell of the accessed object, or any portal of a company where the accessed object is located, and the like. The second node device may refer to any one of a plurality of node devices configured with a chain of access blocks. The second node device may be the same as or different from the first node device, and this is not limited in this embodiment of the application.

When the first object reaches the target area, the second node device acquires identification information of the first object. The identification information of the first object refers to information that uniquely identifies the first object, and may refer to identity information such as a name and an identity document number of the first object, or may refer to a face image of the first object. In a possible implementation manner, the manner in which the second node device acquires the face image of the first object may be: the second node device collects a face image of the first object based on the image collection device. In one possible implementation manner, the manner in which the second node device obtains the identity information of the first object includes, but is not limited to, the following two manners:

the first method is as follows: and the second node equipment displays an information filling interface for the first object to fill in the identity information, and then the second node equipment acquires the identity information filled in by the first object.

The identity information filled in by the first object may include information such as name, sex, identity document number, communication number and the like of the first object.

The second method comprises the following steps: an OCR (Optical Character Recognition) device is installed in the second node device, and when the first object places the identity document at the OCR device, the OCR device of the second node device recognizes the identity information of the first object according to the captured identity document image.

The identified identity information may include information such as name, gender, and identity document number of the first object.

In a possible implementation manner, the second node device may show the identified identity information to the first object for verification, and when receiving a verification passing instruction of the first object, the second node device obtains the identification information of the first object. By the method, the probability of error of the identified identity information can be reduced, and the accuracy of the acquired identification information can be improved.

After acquiring the identification information of the first object, the second node device may query whether there is target reservation information corresponding to the identification information of the first object in the block chain system, where the target reservation information may be reservation information whose reservation time range covers a timestamp of the first object reaching the target area. If yes, go to step 403; if not, the second node device may prompt the first object to be inaccessible to make the first object make a reservation or check whether the identification information is incorrect, etc.

In one possible implementation, the reservation information may include identity information and/or a face image of the accessed first object. The manner for the second node device to query whether the target reservation information corresponding to the identification information of the first object exists in the blockchain system may be: the second node device inquires whether target reservation information matched with the identity information of the first object or matched with the face image of the first object exists in the block chain system. When there is target reservation information matching the identity information of the first object or matching the face image of the first object, it is described that there is target reservation information corresponding to the identification information of the first object in the block chain system, and at this time, step 403 is performed.

403. The second node device acquires target reservation information corresponding to the identification information of the first object in the blockchain system based on the identification information of the first object.

When the target reservation information corresponding to the identification information of the first object exists in the blockchain system, the second node device can acquire the target reservation information corresponding to the identification information of the first object. Wherein the target reservation information is used to indicate a second object to be accessed by the first object.

In one possible implementation manner, the process of the second node device acquiring the target reservation information corresponding to the identification information of the first object in the blockchain system may be: the second node equipment acquires all reservation information corresponding to the identification information of the first object in the block chain system, wherein each reservation information comprises a reservation time range; and taking the reservation information of which the reservation time range covers a first time stamp as target reservation information, wherein the first time stamp is the time stamp of the first object reaching the target area. In the case where the reservation information is generated by the first object, the target reservation information acquired at this time is target reservation information carrying form information corresponding to the identification information of the first object.

The process of the second node device acquiring all reservation information corresponding to the identification information of the first object in the blockchain system may be: the second node device determines an access block chain for storing access information in the configured plurality of block chains; determining all blocks corresponding to the identification information of the first object in the access block chain; all reservation information corresponding to the identification information of the first object is determined in all blocks.

After acquiring the target reservation information corresponding to the identification information of the first object, the second node device may determine whether the second object authorizes the first object to access according to the target reservation information. When the target reservation information indicates that the second object does not authorize the first object to access, the second node device may prompt the first object to be inaccessible; when the target reservation information indicates that the second object authorizes the first object for access, step 404 is performed. It should be noted that, when the reservation information is generated by the first object, the target reservation information indicates that the second object authorizes the first object to perform access means that the form information indicates that the second object authorizes the first object to perform access. That is, when the form information indicates that the second object authorizes the first object to access, the second node apparatus performs step 404.

404. And when the target reservation information indicates that the second object authorizes the first object to access, the second node equipment unlocks the entrance guard of the target area.

When the target reservation information indicates that the second object authorizes the first object to access, the first object can enter the area where the second object is located to access the second object, and at the moment, the second node device unlocks the entrance guard of the target area to allow the first object to enter the area where the second object is located.

In a possible implementation manner, the manner in which the second node device unlocks the entrance guard of the target area may be: the second node device is in communication connection with the device for controlling the access control switch of the target area, when the target reservation information indicates that the second object authorizes the first object to access, the second node device sends an unlocking instruction to the device for controlling the access control switch of the target area, and the device for controlling the access control switch of the target area unlocks the access control of the target area.

Compared with the access control unlocking process in the related technology controlled by a guard, the access control unlocking process in the embodiment of the application is controlled by the second node device in the block chain system, when the second node device confirms that the target reservation information stored in the block chain system indicates that the second object authorizes the first object to access, the access control unlocking process is automatically executed, the phenomenon that the guard and a visitor maliciously collude to harm the safety of the resident can be effectively avoided, the reliability of the access information processing process is high, and the personal and property safety of the accessed second object can be improved.

405. The second node device acquires first image information of the first object based on the image acquisition device, takes identification information of the first object and the first image information of the first object as access registration information of the first object, and stores the access registration information in the block chain system.

The first image information refers to image information obtained by shooting the first object by the image acquisition device before the first object enters the area where the second object is located. The first image information includes face information of the first subject. The access registration information refers to information when the first object enters the area where the second object is located, and includes, but is not limited to, identification information of the first object, first image information of the first object, and the like.

After the entrance guard of the target area is unlocked, it is indicated that the first object can enter the area where the second object is located, and at the moment, the second node device acquires the first image information of the first object, so that the behavior of the first object in the area where the second object is located can be monitored conveniently according to the first image information.

In one possible implementation, the manner in which the second node device acquires the first image information of the first object includes, but is not limited to, the following two manners:

the first method is as follows: the second node equipment is provided with an image acquisition device, and directly acquires first image information of the first object shot by the image acquisition device.

The image acquisition device may be a camera or a camera, which is not limited in the embodiment of the present application. When the image acquisition device performs shooting, the face area of the first object may be identified, and then an image including the face area may be shot.

The second method comprises the following steps: the second node equipment is in communication connection with the image acquisition device, after the entrance guard of the target area is unlocked, the second node equipment sends an image acquisition instruction to the image acquisition device, the image acquisition device shoots the first object based on the image acquisition instruction, then first image information of the shot first object is sent to the second node equipment, and therefore the second node equipment obtains the first image information of the first object.

Similarly, when the image capturing apparatus performs shooting, the face area of the first subject may be identified, and then an image including the face area may be shot.

After acquiring the first image information of the first object, the second node device may use the identification information of the first object and the first image information of the first object as access registration information of the first object, and store the access registration information of the first object in the block chain system. The process of the second node device storing the access registration information in the blockchain system may refer to the process of the first node device storing the reservation information in the blockchain system in step 401, which is not described herein again.

After the access registration information is stored in the blockchain, the access registration process of the first object is completed, the registration process is confirmed by the blockchain system, and the efficiency and the safety of the registration process are high.

406. And the third node equipment receives the access process information of the first object, generates early warning information when the access process information indicates that the first object has abnormal behavior, and stores the early warning information in the block chain system.

Wherein the access progress information is used to indicate a behavior of the first object that occurs after reaching the target area and before leaving the target area.

After the second node device stores the access registration information in the blockchain system, the first object enters the area where the second object is located, for example, the first object enters a cell where the second object lives or enters a company where the second object is located, and the like. At this time, the node device in the blockchain system may monitor the behavior of the first object in the area where the second object is located, obtain the access process information of the first object, broadcast the access process information in the blockchain system, and then the third node device may receive the access process information of the first object.

In one possible implementation, the access progress information of the first object includes, but is not limited to, confirmed access information and confirmed leave information of the first object. The confirmed visiting information is used for indicating that the first object arrives at the appointed place with the second object, and the confirmed leaving information is used for indicating that the first object leaves the appointed place with the second object. For example, when the appointed place is the address of the second object, the confirmation visiting information is information confirming that the first object arrives at the address of the second object, and the determination leaving information is information confirming that the first object leaves the address of the second object. The confirmed visit information may include a third timestamp of confirmed visit and the confirmed departure information may include a fourth timestamp of confirmed departure.

Both the confirmed access information and the confirmed departure information of the first object may be broadcast into the blockchain system by the terminal of the second object. When the first object reaches a location agreed with the second object, the second object may generate acknowledgement information of the first object at the terminal, and then the acknowledgement information is broadcasted into the blockchain system by the terminal of the second object. When the first object leaves the location agreed with the second object, the second object may generate the confirmed leave information of the first object at the terminal, and then the confirmed leave information is broadcasted into the blockchain system by the terminal of the second object.

After receiving the access process information of the first object, the third node device may determine whether the first object has an abnormal behavior according to the access process information. And when the access progress information indicates that the first object has abnormal behavior, the third node device generates early warning information and stores the early warning information in the block chain system.

The situation that the first object has abnormal behavior includes, but is not limited to, the following:

the first condition is as follows: the third node device does not receive the acknowledgement of the first object within a time range from the first timestamp by the first time interval.

Wherein the first timestamp refers to a timestamp of the first object reaching the target area. Taking the residential cell of which the target area is the second object and the appointed place as the residence of the second object as an example, the case where the first object does not reach the residence of the second object for a long time after entering the residential cell of the second object will be described. At this time, the first object may be considered to have abnormal behavior.

The first time interval may be set empirically or may be freely adjusted according to an application scenario, which is not limited in the embodiment of the present application. For example, the first time interval may be set to 20 minutes, etc.

Case two: the acknowledge away information of the first object is not received within a time range of a second time interval from the third timestamp.

Wherein the third timestamp refers to a timestamp at which the first object confirmed the visit. Taking a residential cell whose target area is the second object and an appointed place as the residence of the second object as an example, this case illustrates that the first object does not leave the residence of the second object for a long time after arriving at the residence of the second object. At this time, the first object may be considered to have abnormal behavior.

The second time interval may be set empirically or may be freely adjusted according to an application scenario, which is not limited in this embodiment of the application. For example, the second time interval may be set to 2 hours, etc.

Case three: in a time range from the fourth time stamp by the third time interval, the first object is not detected to leave the target area.

Wherein the fourth timestamp refers to a timestamp of the first object confirming the departure. Taking the residential cell of which the target area is the second object and the appointed place as the residence of the second object as an example, the case where the first object does not leave the residential cell of the second object for a long time after leaving the residence of the second object will be described. At this time, the first object may be considered to have abnormal behavior.

The third time interval may be set empirically or may be freely adjusted according to an application scenario, which is not limited in this embodiment of the application. For example, the third time interval may be set to 20 minutes, etc.

And when the third node device determines that the access process information indicates that the first object has abnormal behavior according to the condition, the third node device generates early warning information and stores the early warning information in the block chain system. The early warning information may include an early warning timestamp, an abnormal reason, and the like. After the early warning information is stored in the block chain system, the fourth node device configured with the access block chain can acquire the early warning information and then perform corresponding processing according to the early warning information. The way in which the fourth node device processes according to the warning information may be different according to different situations in which the first object has abnormal behavior. The following is a detailed description:

when the first object has the abnormal behavior, that is, the first object is a node that; when the information fed back by the terminal of the second object is that the first object has arrived at the location appointed by the second object, the fourth node device may broadcast the information fed back by the second object to the blockchain system; when the information fed back by the terminal of the second object is that the second object does not arrive at the place appointed by the second object, or when the information fed back by the terminal of the second object is not received for a long time, the fourth node device can acquire the monitoring video information of the first object in the block chain system, determine the position of the first object according to the monitoring video information, broadcast the position to the block chain system, and meanwhile, the fourth node device can inform the property staff to check the condition of the first object at the position. It should be noted that the source manner of the monitoring video information of the first object may be: the monitoring node equipment collects monitoring videos in a shooting range in real time and broadcasts the collected monitoring videos to a block chain system; the video analysis node equipment in the block chain system extracts the monitoring video information of the first object from the monitoring video broadcast by the monitoring node equipment according to the first image information of the first object, and then broadcasts the monitoring video information of the first object to the block chain system.

When the second situation is that the first object has abnormal behavior, the fourth node device may generate an inquiry request to the terminal of the second object, so that the terminal of the second object feeds back information whether the first object leaves a place agreed with the second object; when the information fed back by the terminal of the second object is that the first object leaves the place appointed by the second object, or when the information fed back by the terminal of the second object is that the first object does not leave the place appointed by the second object, the fourth node device may broadcast the information fed back by the second object to the blockchain system; when information fed back by a terminal of the second object is not received for a long time, the fourth node device can acquire monitoring video information of the first object in the blockchain system, determine the position of the first object according to the monitoring video information, broadcast the position to the blockchain system, and meanwhile, the fourth node device can inform property staff to check the condition of the first object at the position.

When the situation that the first object has the abnormal behavior is the third situation, the fourth node device may acquire the monitoring video information of the first object in the blockchain system, determine the location of the first object according to the monitoring video information, broadcast the location to the blockchain system, and meanwhile, the fourth node device may notify property staff to view the situation of the first object at the location.

When the access process information indicates that the first object has abnormal behavior, early warning information is generated in time, so that the fourth node device can process in time, and the second object can be prompted to pay attention to safety, thereby avoiding personal and property loss of the second object and improving the safety of the area where the second object is located.

407. And the second node equipment acquires the access end information of the first object and stores the access end information in the block chain system.

When the first object leaves the target area, the second node apparatus may acquire the access end information of the first object to verify the access registration information of the first object.

In one possible implementation manner, the process of the second node device acquiring the access end information of the first object may include the following three steps:

the method comprises the following steps: the second node device acquires second image information of the first object based on the image acquisition device.

The second image information is image information obtained by shooting the first object by the image acquisition device before the first object leaves the area where the second object is located. The second image information includes face information of the first subject. When the first object is about to leave the target area, the second node device acquires second image information of the first object. In one possible implementation, the manner in which the second node device acquires the second image information of the first object includes, but is not limited to, the following two manners:

the first method is as follows: the second node equipment is provided with an image acquisition device, and directly acquires second image information of the first object shot by the image acquisition device.

When the image acquisition device performs shooting, the face area of the first object may be identified, and then an image including the face area may be shot.

The second method comprises the following steps: the second node equipment is in communication connection with the image acquisition device, the image acquisition device shoots the first object and then sends second image information of the shot first object to the second node equipment, and therefore the second node equipment obtains the second image information of the first object.

Step two: the second node device acquires, in the blockchain system, identification information of the first object corresponding to the second image information based on the second image information.

The specific implementation process of the step can be as follows: the second node equipment acquires first image information corresponding to the second image information in the block chain system based on the second image information; determining access registration information corresponding to the first image information based on the first image information; the identification information of the first object in the access registration information is taken as the identification information of the first object corresponding to the second image information.

In one possible implementation manner, the manner in which the second node device acquires the first image information corresponding to the second image information in the blockchain system may be: the second node device compares the face information in the second image information with the face information in each of the first image information stored in the blockchain system, and takes the first image information with the face information similarity exceeding a similarity threshold as the first image information corresponding to the second image information. The similarity threshold may be set empirically, or may be freely adjusted according to an application scenario, which is not limited in the embodiment of the present application. For example, the similarity threshold may be set to 95%, etc.

Step three: and taking the identification information, the second timestamp and the second image information of the first object as access end information of the first object, and storing the access end information in the block chain system.

Wherein the second timestamp is a timestamp of the first object leaving the target area. The access end information refers to information when the first object leaves the area where the second object is located, and includes, but is not limited to, identification information of the first object, a second timestamp, and second image information of the first object.

The process of the second node device storing the access end information in the blockchain system may refer to the process of the first node device storing the reservation information in the blockchain system in step 401, which is not described herein again.

After storing the access end information in the blockchain system, the access registration information of the first object is verified, which is equivalent to the first object completing the whole access process. The automatic verification mechanism is more convenient and safer.

In summary, the access information processing procedure based on the blockchain may be as shown in fig. 7, where the first object or the second object makes a reservation, and the node device stores the reservation information in the blockchain system; when the first object reaches the target area, the node equipment checks the first object based on reservation information in the block chain system, when the reservation information indicates that the second object authorizes the first object to access, the access control of the target area is unlocked, access registration information of the first object is obtained, and the access registration information of the first object is stored in the block chain system; receiving access process information, when the access process information indicates that the first object is abnormal in behavior, generating early warning information by the node equipment, and then taking corresponding measures by property personnel; when the first object is about to leave the target area, the node device acquires access end information and stores the access end information in the blockchain system. The access information processing process can effectively prevent the first object with unknown identity from entering and exiting the area where the second object is located at will, improves the safety of the area where the second object is located, and has very important significance on the personal safety and the property safety of the second object. The access information of the whole access process of the first object is stored in the block chain system, so that the accuracy and the integrity of the access information can be ensured, and the tracing and the management of the access information are facilitated.

In the embodiment of the application, target reservation information is acquired in the block system based on the identification information of the first object, and when the target reservation information indicates that the second object authorizes the first object to access, the access control of a target area is unlocked. In the process of processing the access information, the node equipment automatically processes the information of the first object in the process of accessing, so that the labor cost is saved, and the processing efficiency of the access information is higher. In addition, because the information on the block chain can not be tampered, the node equipment realizes the unlocking of the access control based on the information stored in the block chain, the phenomenon that the security of residents is harmed by malicious communication between entrance guard personnel and visitors can be effectively avoided, the reliability of the access information processing process is high, and the personal and property safety of the accessed second object can be improved.
