In one embodiment, as shown in Fig. 2, step S2, screening node include the following steps:
Step S201, using DPoS common recognition mechanism: common recognition mechanism is used to select using DPoS common recognition mechanism, DPoS common recognition mechanism
The node of predetermined number out.
DPoS knows together mechanism (share authorisation verification mechanism), and principle is that the people for allowing each to hold bit stock throws
Thus ticket generates 101 representatives, i.e. 101 nodes, 101 mutual rights of node are essentially equal.DPoS common recognition mechanism
It is by different strategies, a small set of node is chosen in not timing, this selected a small set of node does new district when specific works
Creation, verifying, signature and the mutually supervision of block, have been greatly reduced the time consumed required for block creation and confirmation and calculation
Power cost.This step knows together mechanism by using DPoS to filter out the computer of 101 medical institutions as predetermined number
Node.
Step S202, ballot screening node: the node in P2P network is registered on block catenary system, and receives other sections
The ballot of point, common recognition mechanism records the votes of node after the ballot for receiving all nodes, default before number of votes obtained is highest
The node of number will obtain right of keeping accounts in turn.
Node in registration, i.e., the registered public keys on block catenary system, then distribute to by the common recognition mechanism of block catenary system
Node one 32 identifiers of registration, unique encodings of this identifier as the node.After the completion of registration, node both can be with
It votes to other nodes, also can receive the ballot of other nodes.The votes that each node is recorded by common recognition mechanism will be thrown
Poll is arranged from high to low, and number of votes obtained is come preceding 101 nodes and obtains right of keeping accounts in turn.
Step S203 keeps accounts in turn: the node filtered out obtains right of keeping accounts in turn according to preset timetable, machine of knowing together
Medical data information is sent to the node filtered out according to this preset timetable by system in turn.
Preset timetable, which can be, successively sent medical number to 101 nodes by 10 seconds, 20 seconds or 30 seconds periods
It is believed that breath.The a certain node for obtaining right of keeping accounts in turn, when establishing new data block, the note of common recognition mechanism record new data block
It records the time, when new data block broadcasts the period more than 10 seconds, 20 seconds or 30 seconds from establishing the whole network, then it is assumed that obtain in turn
The node of book keeping operation right misses the right of record new data block, this medical data information is sent to next obtain by common recognition mechanism
The node for obtaining right of keeping accounts in turn replaces completing book keeping operation.
The present embodiment is screened, distributed and is supervised to the node in P2P network by DPoS common recognition mechanism, can be substantially
The time for reducing consumption required for block creates and confirms of degree and calculation power cost.
In one embodiment, as shown in figure 3, step S3, node book keeping operation include the following steps:
Step S301 establishes new data block: after node obtains medical data information, establishing new data block, new data
Block includes block head and block body, and block head records the Merkle root of previous block, the Merkle root of current block, time
Stamp, block body record medical data information, and timestamp is time when new data block is established.
As shown in figure 4, each data block includes block head and block body, block head includes the Merkle of previous block
The cryptographic Hash of root, the Merkle root of current block, timestamp, Merkle root, the interior medical data information recorded of block body.
Step S302, record the Merkle root of current block: the medical data information of acquisition is passed through Merkle root by node
Hash function calculate in the Merkle root for generating the current block of unique Merkle root record to block head.
Merkle tree is the important component of block catenary system, and effect is the medical number by operation for hashed value
It is believed that breath gets up according to binary tree structure organization.The generating process of Merkle tree are as follows: breathe out medical data information grouping
Uncommon function calculates, and new hashed value is put back to, then takes out 2 data again and carry out operation, and recurrence is gone down always, until being left only
One Merkle root.This step uses the advantages of Merkle tree, i.e., good scalability, regardless of how medical data information is
, a Merkle tree can be generated.And the time complexity of lookup algorithm is very low, also is easy to trace to the source from bottom to find
Merkle root whether there is or legal to carry out book keeping operation, greatly reduce resource occupation when operation.This step passes through application
The create-rule of Merkle tree calculates the current block for generating unique Merkle root record to block head by hash function
In Merkle root, this unique identification of unique Merkle root as current block.
Step S303, recording areas block: node encrypts medical data information by rivest, shamir, adelman, charges to
Into block body.
Rivest, shamir, adelman in this step can use following algorithm:
(1) two different Big prime p and q are selected；
(2) product n=pq and Φ (n)=(p-1) (q-1) of Big prime are calculated；
(3) selection is greater than the 1 random integers e for being less than Φ (n), so that greatest common divisor gcd (e, Φ (n))=1；
(4) it calculates d and makes d × e=1mod Φ (n) (i.e. d × e mod Φ (n)=1)；
(5) to each key k=(n, p, q, d, e), definition enciphering transformation is Ek (x)=xe mod n, decryption transformation
For Dk (x)=yd mod n；
(6) p, q are destroyed, and with { e, n } for public-key cryptography, { d, n } is private cipher key, wherein public key for encrypting, use by private key
In decryption.
In this step, node is logged into block body using the public key of { e, n } after encrypting to medical data information,
Guarantee the safe and reliable of data.
Step S304 forms new block chain: obtaining the node of book keeping operation right by chain structure, current block is linked
To after previous block, and the Merkle root of previous block is recorded, causes to form new block chain.
In this step, current block is linked on existing block chain, medical data information permanent will store
Come, unless can control simultaneously be more than in block catenary system 51% node, otherwise to the modification of database on individual node
Be it is invalid, the stability and reliability of the medical data information in block chain entire in this way are high.
The present embodiment calculates the Merkle root for generating current block by the hash function to medical data information, to doctor
It treats data information rivest, shamir, adelman to be logged into block body, forms new data block, and be linked in block chain, realize
The purpose that each node can keep accounts, each node right obtained is identical, and the accounting mode of decentralization ensure that block
The stabilization and safety of medical data information on chain.
In one embodiment, it as shown in Figure 1, new data block is linked to last data block by node, is formed new
Further include step S4 after block chain, data broadcasting is verified:
Other nodes that will be verified message by generating the node of the data block and be broadcast in P2P network, in P2P network
Other nodes carry out data verification to new data block, and verification result is notified common recognition mechanism, the institute that common recognition mechanism receives
When to have verification result be effective, it is believed that all nodes in P2P network all approve that this new data block is linked in block chain,
All verification results that common recognition mechanism receives there are it is invalid when, it is believed that this new data block is invalid, by it from block chain
It removes, this corresponding medical data information of new data block is sent to next node for obtaining right of keeping accounts in turn and is remembered
Account.
Verifying message in this step refers to this message of the new data block of generation, other nodes receive this message
Afterwards, new data block verifies data by Merkle root, specific verification process is as shown in Figure 5, and steps are as follows:
Step S401 is broadcasted one by one: the node for obtaining right of keeping accounts in turn is broadcast in P2P network will verify message
When other nodes, by the way of being broadcasted one by one to neighbor node, wherein verifying message is the number of the block head of new data block
It is believed that breath.
Due to using the networking mode of P2P network between each node, it can be based on P2P network, used between node
The mode broadcasted to neighbor node one by one propagates verifying message.
Node verification validity: step S402 after any node receives the verifying message that neighbor node transmits, will be counted newly
Carry out verifying validity according to the data structure of block, syntax gauge, for verify it is effective when, will verifying message to neighbor node after
Continuous to be broadcasted, when for verifying message invalid, node does not do the operation of verifying message forwarding.
In this step, when node verifies new data block, node does not have to save whole block chain data, it is only necessary to
Save comprising needing in the new data block verified, the block head of the Merkle root comprising current block can, traced back by bottom
The Merkle root that source finds new data block, which carrys out verify data, whether there is or effectively.It is to current block when specific verifying
Merkle root data structure and syntax gauge whether meet unique Merkle root of a Merkle tree to determine.
In this step, the node being broadcasted in P2P network refers to the node of the predetermined number filtered out by common recognition mechanism, that is, sieves
101 selected obtain the node for right of keeping accounts in turn, and the node not screened haves no right to verify new data block, to reduce block
The time of consumption required for creating and confirming and calculation power cost.
The present embodiment, by increasing data broadcasting verification step, the data block for keeping each newly-generated is by P2P network
In other nodes approve after, be just linked on block chain, nodes all in this way all has fair book keeping operation and supervision right,
Further ensure the safe and reliable of all data blocks on block chain.
