Fig. 3 A are a kind of flow charts of data matching method according to an exemplary embodiment, as shown in Figure 3 B, should
Method comprises the following steps.
In step 301, public key of the first node based on Section Point is encrypted to the first random string, obtains first close
Text, and the first ciphertext is added to block chain.
In the disclosed embodiments, first node and Section Point are the node on the block chain of data-sharing systems.
Data-sharing systems refer to be used to carry out data sharing between node and node, the system for determining node and node common factor data.
For each node in data-sharing systems, it is respectively provided with corresponding public key and private key, data-sharing systems and each saves
The public key of point known by other nodes in data-sharing systems, and the private key of each node only its own know.Data
Each node in shared system stores an identical block chain, namely is stored with one on first node and Section Point
Bar identical block chain, block chain is made up of multiple blocks, and each block is stored with different data, the whole on block chain
The shared data of node where the data of block storage constitute block chain.When a certain node in data-sharing systems is to block
When the data such as ciphertext, filter algorithm are added in chain, one can be increased newly in the block chain of whole nodes in data-sharing systems
The block chain stored in individual block, namely first node and Section Point can increase a block newly, it is ensured that in data sharing
The data of each node block chain are consistent.
It was recognized by the inventor that node in data-sharing systems is it is determined that during common factor data, if by shared to be matched
Data realize that then the confidentiality of data to be matched is not high, it is likely that can be by the leaking data to be matched of a certain node, therefore, can
By the way that data to be matched on node are encrypted, to obtain encryption data, and filter algorithm is generated based on encryption data,
Each node to treat matched data based on filter algorithm to be filtered, it is determined that common factor data, without by number to be matched
According to being disclosed.So, just need each node to treat matched data based on same standard to be encrypted, this standard
As encrypted characters string.In actual applications, the encrypted characters string can be the salt in cryptography, the substantially specific word of salt
Symbol string, so, node can first treat matched data and do when treating matched data based on encrypted characters string and being encrypted
Such as MD5 (Message-Digest Algorithm 5, message digest algorithm 5) hashing, and encrypted characters string is inserted
Enter the predeterminated position of the data to be matched to hashing, obtain encryption data.It should be noted that in the embodiment of the present disclosure
In, it can be above-mentioned salt that each node, which treats the encrypted characters string used when matched data is encrypted, in order that encryption
Character string is generated jointly by the node of pending Data Matching, can for pending Data Matching node distribution it is corresponding with
Machine character string so that encrypted characters string is made up of the random string of the node of pending Data Matching, it is ensured that carrying out data
To the fairness of node during matching.In addition, for convenience of description, in the disclosed embodiments, with first node and Section Point
Illustrated exemplified by Data Matching, wherein, the random string that first node is assigned to is the first random string, second
The random string that node distribution is arrived is the second random string.
Due to there may be multigroup node for needing to generate encrypted characters string in the same time, in order to avoid in generation encryption
Made a mistake during character string, therefore, first node by the first random string of itself when sharing to Section Point, it is necessary to base
The first random string is encrypted in the public key of Section Point, the first ciphertext is generated and the first ciphertext is added to block
Chain, due to Section Point private key only its own know that therefore, first node only has second added to the first ciphertext of block chain
Node can be decrypted, it is to avoid make a mistake.
In step 302, Section Point obtains the first ciphertext from block chain, and the private key based on Section Point is to the first ciphertext
Decryption, obtains the first random string, and the second random string is attached into the afterbody of the first random string, generates encryption
Character string.
In the disclosed embodiments, because public key of first ciphertext based on Section Point is encrypted, therefore, Section Point
After the first ciphertext is got, just ciphertext can be decrypted based on the private key of Section Point, so as to obtain first node
First random string.Section Point just can be based on the first random words after the first random string of first node is obtained
Symbol string and the second random string generation encrypted characters string of itself, enter subsequently to treat matched data based on encrypted characters string
Row encryption.In general, Section Point is based on the first random string and the second random string generation encrypted characters
During string, the second random string can be attached to the afterbody of the first random string, the second random string can also be added
On the head of the first random string, the embodiment of the present disclosure is to this without specific restriction.
In step 303, public key of the Section Point based on first node serially adds close to encrypted characters, obtains the second ciphertext,
And the second ciphertext is added to block chain.
In the disclosed embodiments, made a mistake in order to avoid other nodes obtain the encrypted characters string in block chain, the
Two nodes generation encrypted characters string after, can the public key based on first node encrypted characters string is encrypted, obtain second close
Text, block chain is added to by the second ciphertext, so that first node obtains the second ciphertext in block chain, and the second ciphertext is carried out
Decryption.
In step 304, first node obtains the second ciphertext from block chain, and the private key based on first node is close to second
Text decryption, is obtained encrypted characters string, the first data to be matched is encrypted based on encrypted characters string, and number is encrypted in generation first
According to.
In the disclosed embodiments, after the second ciphertext is added to block chain by Section Point, due to the area of each node
Data on block chain are consistent, then can also have the second ciphertext on the block chain of first node, so, first node just may be used
To obtain the second ciphertext on block chain, and the second ciphertext is decrypted, obtain encrypted characters string.
First data to be matched are that will be matched on first node with the data on Section Point, to determine to occur simultaneously
The data of data.First node encrypted characters string can be used to add the first data to be matched after encrypted characters string is obtained
It is close, the first encryption data is generated, subsequently to generate the first filter algorithm based on the first encryption data so that Section Point can be with
Data are filtered based on the first filter algorithm.
