Referring to FIG. 2, the management method of the information of vehicles provided it illustrates the application one embodiment.This method can be with Applied to the vehicle management equipment in the network architecture shown in FIG. 1.This method may include the following steps.

Step 201, the information of vehicles for needing typing is obtained.

Firstly, vehicle management equipment obtains the information of vehicles for needing typing.Wherein, information of vehicles includes at least a vehicle Vehicles identifications.Vehicles identifications are for uniquely indicating an automobile, such as vehicle identification code (Vehicle Identification Number, VIN), alternatively, with the one-to-one Hash encrypted code of vehicle.According to the corresponding manager of vehicle management equipment and make With scene difference, information of vehicles further includes other data informations.For example, information of vehicles also wraps if manager is production firm Include detailed configuration information when vehicle production；If manager is vehicle transport department, information of vehicles further includes that logistics is conveyed through Release information in journey；If manager is secondhand sales shops, information of vehicles further includes emm message of the vehicle to shop.

Step 202, according to information of vehicles, Merkel's cryptographic Hash is generated.

Merkel's cryptographic Hash that vehicle management equipment generates is for uniquely indicating a block in block chain.Because one Merkel's cryptographic Hash of block is generated according to the information data recorded in the block, so the information data in block occurs When variation, the corresponding Merkel's cryptographic Hash of block can also change.Therefore, vehicle management equipment generates silent according to information of vehicles Ke Er cryptographic Hash, if distorted to information of vehicles, information of vehicles and Merkel's cryptographic Hash after distorting simultaneously are mismatched, thus User can be found that information of vehicles is tampered.By the corresponding relationship between block, information of vehicles and Merkel's cryptographic Hash, guarantee Information of vehicles be recorded after block can not tamper.

Step 203, block sequence block is generated.

Block chain is written in information of vehicles by vehicle management equipment, needs to complete by way of generating block sequence block. The block chain block includes the information of vehicles for needing typing and corresponding Merkel's cryptographic Hash.The information for including in block chain block The data capacity of data is fixed, therefore the quantity of the information of vehicles in block chain block is limited.Vehicle management equipment It needs after obtaining the information of vehicles being consistent with the capacity of block chain block, regeneration block chain block is recorded.Therefore, when The quantity of information of vehicles in one block chain block is greater than for the moment, and the information of vehicles in the block chain block can be different vehicles Information of vehicles, such as manager is production firm, may include four information of vehicles in block chain block, then production firm Vehicle management equipment get the information of vehicles of four automobiles after, regeneration block chain block record together.

Step 204, block sequence block is broadcasted in block catenary system.

According to the common recognition mechanism in block chain technology, record is had the block of information of vehicles to be added to area by vehicle management equipment Before block chain, the verifying by the other equipment of block catenary system is needed.All devices in block catenary system include at least other The vehicle management equipment and back-stage management equipment of manager.Therefore, vehicle management equipment broadcasts block chain in block catenary system Block, so that the legitimacy of other node devices verification block sequence block in block catenary system.Verify block sequence block Legitimacy is really to verify whether vehicle management equipment has by the permission of information of vehicles write-in block chain, to prevent no permission The false information of vehicles of equipment write-in.If vehicle management equipment has the permission of information of vehicles write-in block chain, the vehicle The block chain block that management equipment generates is legal；If the permission of block chain is not written in information of vehicles by vehicle management equipment, The block chain block that then the vehicle management equipment generates is illegal.

Step 205, if block chain block is legal, block chain block is added in block chain.

Block chain block is added to block if the block chain block that vehicle management equipment generates is legal by verification Chain completes the process of information of vehicles write-in block chain.Block chain is the data-link for being joined end to end by multiple data blocks and being formed. Block chain block is added to block chain, refers to the end for being added to block chain using block chain block as newest data block End.

In the embodiment of the present application, vehicle management equipment stores vehicle in such a way that block chain is written in information of vehicles Information.Using block chain technology, the vehicle management equipment of different managers is placed in same block catenary system, different vehicles Management equipment is all based on same block chain management information of vehicles.During block chain is written in information of vehicles, pass through Merck Your cryptographic Hash guarantees that the information of vehicles of record can not be distorted, then by the verification to block chain block legitimacy, avoids write-in empty False information of vehicles.Therefore information of vehicles can be prevented to be tampered, the reliability and safety of information of vehicles is improved, so that user The real information of vehicle can be obtained.

Referring to FIG. 3, it illustrates the flow charts of the management method of the information of vehicles of the application one embodiment offer.It should Method can be applied in the network architecture shown in FIG. 1.This method may include the following steps.

Step S301, vehicle management equipment transmit into chain request to backstage management equipment.

In vehicle since the life cycle production, there are multiple managers.Each manager requires to add or repair Positive information of vehicles.Before information of vehicles is written into block chain using vehicle management equipment in manager, vehicle management equipment needs Block catenary system is first added, obtains the permission of access block chain.Therefore, vehicle management equipment transmits into chain to backstage management equipment Request.This enters the identity information including the corresponding manager of the vehicle management equipment in chain request.For example, manager is sale door Shop, then the identity information of the manager includes business license number, shops address and corporate message etc..

Whether step S302, back-stage management equipment detection identity information meet preset condition.

In block catenary system, can block catenary system be added by back-stage management equipment verification vehicle management equipment, is obtained Access the permission of block chain.After vehicle management equipment transmits into chain request, correspondingly, back-stage management equipment is received asks into chain It asks.Whether the identity information that back-stage management equipment detects in chain request meets preset condition.Wherein, preset condition is vehicle pipe It manages equipment and block catenary system is added, and obtain the permission condition to be met of access block chain.If identity information meets default Condition, then back-stage management equipment determines that block catenary system can be added in vehicle management equipment, and executes step S303；If identity is believed Breath does not meet preset condition, then back-stage management equipment determines that block catenary system cannot be added in vehicle management equipment, refuses vehicle pipe Reason equipment enters chain request.

According to vehicle management equipment, corresponding manager is different, and above-mentioned preset condition is also different.For example, for selling door Shop, preset condition include that business license number is effective；For car test mechanism, preset condition includes having vehicle detection qualification.Therefore, Preset condition is preset with actual manager based on practical experience.

Optionally, it is above-mentioned enter chain request further include vehicle management equipment facility information.Facility information includes hardware configuration Information, communications address information and security log information.Whether back-stage management equipment detects vehicle management equipment according to facility information Meet the hardware and safety standard that block catenary system is added.Wherein, hardware and safety standard can be set in advance based on practical experience It is fixed.If meeting the hardware and safety standard that block catenary system is added, back-stage management equipment determines that vehicle management equipment can add Enter block catenary system；If not meeting the hardware and safety standard that block catenary system is added, back-stage management equipment determines vehicle pipe Block catenary system cannot be added in reason equipment.

Step S303, back-stage management equipment transmit into chain response to vehicle management equipment.

After back-stage management equipment determines that block catenary system can be added in vehicle management equipment, transmitted into vehicle management equipment Chain response.This enters chain response and is used to indicate the permission that vehicle management equipment has in block catenary system.Although block chain technology In, each node of same block chain network can access all information in block chain.But in the area of the embodiment of the present application In block catenary system, although the information in block chain all can be inquired and be verified to all vehicle management equipment.But back-stage management equipment Different access authority can be distributed to different vehicle management equipment.For example, for vehicle transport department, back-stage management equipment point The permission matched does not allow vehicle management equipment to read and write owner information.Therefore, enter chain response and be applied not only to notice vehicle pipe Reason equipment has entered chain, also indicates the permission that vehicle management equipment has in block catenary system.

Optionally, entering chain response includes the corresponding access key of vehicle management equipment.The access key is used to indicate vehicle The access authority of management equipment.When vehicle management equipment is read or information is written, vehicle management equipment is read by key pair Or the request of write-in is signed.If vehicle management equipment is read or the information of write-in is in the permission indicated by access key, Then block catenary system allows to access the request that key is signed；If vehicle management equipment is read or the information of write-in is not close in access In permission indicated by key, then block catenary system does not allow to access the request that key was signed.

Step S304, vehicle management equipment obtain the information of vehicles for needing typing.

Firstly, vehicle management equipment obtains the information of vehicles for needing typing.Wherein, information of vehicles includes at least a vehicle Vehicles identifications.Vehicles identifications are for uniquely indicating an automobile, such as vehicle identification code, alternatively, breathing out correspondingly with vehicle Uncommon encrypted code.According to the corresponding manager of vehicle management equipment and usage scenario difference, information of vehicles further includes other data letters Breath.For example, if manager is production firm, detailed configuration information when information of vehicles further includes vehicle production；If manager It is vehicle transport department, then information of vehicles further includes the release information during logistics is transported；If manager is secondhand sales door Shop, then information of vehicles further includes emm message of the vehicle to shop.

In addition, because may include more than one vehicle letter in one block when subsequent step generates block sequence block Breath, so vehicle management equipment, when obtaining information of vehicles, a plurality of information of vehicles of an available automobile is also available The information of vehicles of more automobiles.

Optionally, vehicle management equipment can obtain information of vehicles by information acquisition terminal, such as be adopted by image Collection equipment scratches information determine Vehicle surface.Vehicle management equipment can also obtain vehicle by way of manual entry Information.

Step S305, vehicle management equipment generate Merkel's cryptographic Hash according to information of vehicles.

Vehicle management equipment arranges information of vehicles according to symmetric binary tree, generates Merkel tree.Merkel tree is a kind of Binary tree, including one group of leaf node, one group of intermediate node and a root node.Wherein, root node is located at the most upper of Merkel tree Layer, leaf node are located at the lowest level of Merkel tree.The quantity of each node layer is the half of the quantity of next node layer, and most The quantity of the leaf node of bottom is the quantity of above-mentioned information of vehicles.Value in each node is cryptographic Hash.Vehicle management equipment By the lowest level of Merkel tree to the top layer of Merkel tree, the cryptographic Hash in each node is successively determined.Firstly, for most lower The leaf node of layer, the cryptographic Hash in leaf node are to carry out the result that Hash operation obtains to the data in information of vehicles.Each Leaf node all stores the cryptographic Hash of an information of vehicles.After the cryptographic Hash for determining lowest level leaf node, for intermediate node With the cryptographic Hash of root node, vehicle management equipment carries out Hash operation to the cryptographic Hash of two child nodes of a node again, Obtained value is the cryptographic Hash of the node.By this way, vehicle management equipment successively determines the cryptographic Hash in each node, Until determining the cryptographic Hash of root node, and the cryptographic Hash of root node is determined as above-mentioned Merkel's cryptographic Hash.

Illustratively, as shown in figure 4, it illustrates a Merkel trees.Wherein, Merkel tree includes 4 leaf nodes 401, two intermediate nodes 402 and a root node 403.When determining the cryptographic Hash of each node of Merkel tree, vehicle management Equipment is first according to information of vehicles: L1, L2, L3 and L4.Determine the cryptographic Hash of leaf node 401: hash (L1), hash (L2), hash (L3) and hash (L3), then the cryptographic Hash of intermediate node 402: hash (HashL1+L2) and hash (HashL3+L4) is determined, most The cryptographic Hash of Merkel's cryptographic Hash, that is, root node 403: Hash0 (HashL1+L2+L3+L4) is determined eventually.

Because Merkel's cryptographic Hash is generated according to the information data to be recorded in block, the information in block When data change, corresponding Merkel's cryptographic Hash can also change.Therefore, vehicle management equipment is raw according to information of vehicles At Merkel's cryptographic Hash, by corresponding relationship between the two, guarantee after block is recorded in information of vehicles can not tamper.

Step S306, vehicle management equipment generate block sequence block.

Information of vehicles write-in block chain is needed to complete by way of generating block sequence block by vehicle management equipment.It should Block chain block includes the information of vehicles for needing typing and corresponding Merkel's cryptographic Hash.The block packet that vehicle management equipment generates Include block head and block body.Block head includes above-mentioned Merkel's cryptographic Hash, preceding block cryptographic Hash and block timestamp.Preceding block is breathed out Uncommon value is used to indicate previous block of the corresponding block in block chain, and block timestamp is used to indicate and generates block sequence block Time.Block body includes at least one with the information of vehicles of block transaction storage.In the block of block chain, information data is all It is stored in the form of transaction.In block catenary system, transaction refers not only to traditional transaction, such as the buying and selling of commodities, also Including operating result, data exchange or the data itself to data.Therefore, above-mentioned block transaction is data information in block chain Storage form.In block body, each information of vehicles all exists in the form of a block transaction.Therefore, vehicle management It is really generation area build and block body that equipment, which generates block sequence block,.

Optionally, block head further includes block version number and index mark.Block version number is used to indicate block version.One It may include multiple block transaction in a block.But it when equipment reads the information in a block transaction, needs first to determine and be wanted The position of the information of reading within a block.Index mark is used to indicate the position of information of vehicles within a block, i.e. information of vehicles institute The block of category is traded.In a kind of possible embodiment, the corresponding index mark of information of vehicles is above-mentioned Merkel tree, according to Cryptographic Hash in each node of Merkel's book, can determine corresponding information of vehicles.

Illustratively, as shown in figure 5, it illustrates the 500th blocks in a block chain.The block chain block includes Block head 501 and block body 502.Wherein, block head 501 includes Merkel's cryptographic Hash Hash0 (HashL1+L2+L3+L4), preceding Block cryptographic Hash hash-499, block timestamp 93-2-21-12:12:12 and Merkel tree.Block body 502 includes 4 blocks Transaction.It is information of vehicles respectively in 4 block transaction: L1, L2, L3 and L4.It should be noted that in the example of hgure 5, Merck You are only indicated with virtual module and words identification tree, are not constituted and are limited.To the content of Merkel tree and being discussed in detail for display Fig. 4 example can be referred to.The embodiment of the present application is no longer repeated herein.

Step S307, vehicle management equipment broadcast block sequence block in block catenary system.

Optionally, whether have verification vehicle management equipment by the permission of information of vehicles write-in block chain, block chain Other node devices in system, such as the vehicle management equipment and back-stage management equipment of other managers, can pass through detection Whether information of vehicles in block by above-mentioned access key carried out signature.Accessing key is that back-stage management equipment is sent to vehicle The permission of management equipment proves.Therefore, if there is the corresponding signature of access key, vehicle management equipment, which has, writes information of vehicles Enter the permission of block chain；If not accessing the corresponding signature of key, block is not written in information of vehicles by vehicle management equipment The permission of chain.

Step S308, vehicle management equipment send detection instruction to backstage management equipment.

In practical applications, even if vehicle management equipment has the permission of information of vehicles write-in block chain, manager's sheet Body may also typing falseness information of vehicles.For example, in secondhand sales shops, manager according to the car test information of car test department and The vehicle use information of former car owner fixes a price to vehicle, and price is written in block chain.Car test information and vehicle use Information has stored in block chain, and the manager of secondhand sales shops can not distort.But the price of second-hand vehicle is by second-hand The manager for selling shops determines that manager can be turned up price and make profit.Therefore, block chain block is being added to block Before chain, need to detect the authenticity of information of vehicles.In this regard, vehicle management equipment sends detection instruction to backstage management equipment. The detection instruction is used to indicate whether back-stage management equipment detection information of vehicles is real information.Also, it is wrapped in the detection instruction Include information of vehicles to be detected, the i.e. information of vehicles of the wanted typing of vehicle management equipment.Vehicle management equipment can will need to record All information of vehicles be sent to back-stage management equipment detection, can also with transmitting portion information of vehicles give back-stage management equipment inspection It surveys.The embodiment of the present application does not limit this.

Step S309, back-stage management equipment read information of vehicles and correspond to vehicle stored vehicle letter in block catenary system Breath.

In order to detect whether information of vehicles is real information, back-stage management equipment is according to the vehicle in information of vehicles to be detected Mark determines corresponding vehicle, then obtains vehicle information of vehicles stored in block catenary system.Stored vehicle Information refers to the information having been written into block chain.Because the information in block chain can not distort, stored vehicle letter Breath is real information.

Step S310, back-stage management equipment detect whether information of vehicles is real information according to stored information of vehicles.

According to stored information of vehicles, the information of vehicles that back-stage management equipment can detecte the transmission of vehicle management equipment is No is real information.Between the different vehicle information of one automobile is associated with each other.For example, the mileage number and vehicle of vehicle There is following association between engine usage record: mileage number is directly proportional to the extent of deterioration of engine；The price of second-hand vehicle Exist with the mileage number of vehicle and be associated with as follows: mileage number is higher, and price is lower.Therefore, back-stage management equipment is according to stored Information of vehicles, can determine the value range of other information of vehicles associated there.Back-stage management equipment detects vehicle again Whether the value for the information of vehicles to be detected that management equipment is sent is in above-mentioned value range.If back-stage management equipment determines The information of vehicles to be detected that vehicle management equipment is sent is real information；If not existing, back-stage management equipment determines vehicle management The information of vehicles to be detected that equipment is sent is not real information.Because between information of vehicles be it is associated with each other, deposited There are corresponding relationships between the information of vehicles of storage and above-mentioned value range, and back-stage management equipment is according to the corresponding relationship and has stored Information of vehicles, come determine vehicle management equipment send information of vehicles to be detected value range.Stored information of vehicles After corresponding relationship between the value range of information of vehicles to be detected can be by technical staff based on practical experience preparatory typing Platform management equipment.

Illustratively, the corresponding relationship between the mileage number of second-hand vehicle and the value range of price is as shown in following table -1

Mileage number	Price (original cost percentage)
		<1000km	> 90%
1000-10000km	77%-90%
		10000-100000km	65%-77%
>100000km	< 65%

Table -1

In the corresponding relationship shown in above-mentioned table -1, different mileage numbers corresponds to different price ranges.For example, if vehicle Mileage number is 5689km, then the price of the vehicle should be the 77% to 90% of original cost.When sale, shops wants the typing vehicle When price, price is sent to back-stage management equipment by vehicle management equipment.Correspondingly, back-stage management equipment detection sale shops wants Whether the price of typing is in the 77% to 90% of original cost this value range.

When determining the value range of information of vehicles to be detected, according to different stored information of vehicles, measuring car to be checked The value range of information is also different.Because information of vehicles to be detected is usually associated with multinomial stored information of vehicles, institute With according to different stored information of vehicles, the value range of information of vehicles to be detected is also different.For example, vehicle letter to be detected Breath is the price of second-hand vehicle.The price in addition to vehicle mileage number mutually outside the Pass, also with vehicle model, accident record, insurance It records related to maintenance record.Therefore, according to the determining price range of mileage number and according to mileage number, vehicle model and accident It is not identical to record determining price range.When determining the value range of information of vehicles to be detected, back-stage management equipment institute according to According to stored information of vehicles it is more, determine that value range is more accurate, the testing result of information of vehicles to be detected also got over Accurately.
