Based on Fig. 1 and Fig. 2, Fig. 3 is a kind of data retrieval method based on block catenary system provided in an embodiment of the present invention
Corresponding flow diagram, this method comprises:
Step 301, the retrieval request that the first node at least one data set provider node is sent is received.
In a kind of possible scene, first node 300 or hospital's node；For example, if a certain hospital has received
One patient, the brain of this patient has tumour, and the hospital did not treated the patient of this type, then the hospital can pass through
Retrieval request is submitted to retrieve the intended patient similar with this patient that other hospital's node processings are crossed in the block catenary system.
In one possible implementation, first node 300 can execute retrieving by the way that block catenary system is added.
Specifically, first node 300 can carry out identity registration by supervisory node 400.Specifically, first node 300 can be with
Authentication information is sent to supervisory node 400, may include mark, the first node 300 of first node 300 in authentication information
Organization names, contact method of first node 300 etc..Wherein, the mark of first node 300 can refer to first node 300
Corporate message, for example, legal person ID card No. cryptographic Hash, be specifically not construed as limiting.Correspondingly, supervisory node 400 receives
After the authentication information of one node 300, the legitimacy of authentication information can detecte, such as can be according to the mark of first node 300
It determines first node 300 and whether there is, whether correct, first node 300 the contact method of the organization names of first node 300 is
It is no correct etc.；If it is determined that the authentication information of first node 300 is legal, then it can permit first node 300 and block catenary system be added,
If it is determined that the authentication information of first node 300 is illegal, then the information of authentification failure can be sent to first node 300.
In the examples described above, before being retrieved to the retrieval request that first node is sent, by determining first node
Authentication information it is whether legal, first node can be allowed to retrieve default index database in the case where determining that first node is legal,
Do not allow first node to retrieve default index database in the illegal situation of first node, thereby may be ensured that in default index database
The safety of a plurality of index data improves the safety that data sharing and data retrieval are carried out in block catenary system.
In the embodiment of the present invention, after block catenary system is added in first node 300, the brain of this patient can be shot in advance
CT image is obtained, which can be data to be retrieved；Further, first node 300 can carry out data to be retrieved
Feature extraction and feature encryption obtain the corresponding encrypted feature set of data to be retrieved.It should be noted that obtaining number to be retrieved
According to the process of encrypted feature set be referred to step 201 and realized, details are not described herein again.
Further, search instruction can be generated in first node 300, and search instruction can be sent to retrieval node
200.Wherein, first node 300 generate search instruction mode can there are many, for example, first node 300 can be according to be checked
The type of the corresponding encrypted feature set of rope data, the mark of first node 300 and data to be retrieved generates search instruction, or
Person, first node 300 can be according to the corresponding encrypted feature set of data to be retrieved, the mark of first node 300, number to be retrieved
According to type and retrieval time generate search instruction, be specifically not construed as limiting.In one example, if in search instruction including retrieval
Time, then first node 300 can obtain current time in real time, however, it is determined that the time difference of current time and retrieval time are more than default
Search instruction can then be retransmitted and give retrieval node 300 by duration.
In the embodiment of the present invention, retrieving in node 200 can be set intelligent contract, and therefore, first node 300 sends inspection
After Suo Zhiling, retrieval node 200 can call intelligent contract to obtain search instruction；In this way, the retrieval that first node 300 is sent refers to
Order is obtained by intelligent contract in advance.Further, intelligent contract can parse search instruction obtain data to be retrieved it is corresponding plus
The type of close characteristic set, the mark of first node 300 and data to be retrieved, and can encryption spy corresponding to data to be retrieved
Collection is closed and the mark of first node 300 is verified.Specifically, intelligent contract can first verify data integrality, than
Such as, however, it is determined that the pre-set code of mark or search instruction in search instruction not comprising first node 300 is imperfect, then may be used
To determine that data are imperfect；Further, intelligent contract can determine the corresponding encrypted feature set of data to be retrieved and first
It whether there is invalid data in the mark of node 300, and if it exists, can then filter invalid data, and can be by filtered number
Node 200 is retrieved according to submitting to.
Step 302, at least one index data in default index database is obtained, and according to the characteristic value of data to be retrieved,
The matched target index data of characteristic value with data to be retrieved is obtained from least one index data.
In one possible implementation, retrieval node 200 is available after receiving filtered search instruction
One or more index data (such as 1000) stored in default index database, and then can be according to the type of data to be retrieved
With the type of 1000 index datas, one or more with the type matching of data to be retrieved is chosen from 1000 index datas
Index data (such as 400)；In this way, retrieval node 200 can retrieve this 400 index datas, without right
1000 index datas are retrieved, to substantially reduce workload, improve effectiveness of retrieval.For example, as shown in table 1,
Since data to be retrieved are a brain CT image, the type of data to be retrieved can be brain image, in this way, in table 1
It may include the index data that call number is respectively IM-1, IM-3 and IM-4 with the matched index data of brain image.
In the embodiment of the present invention, by storing the type of one or more index data in default index database, it can make
The process that one or more index data must be retrieved is more flexible and efficient, for example, according to the class of one or more index data
Type, available at least one index data with the type matching of data to be retrieved, thus based on the class with data to be retrieved
Matched at least one index data of type executes retrieval, can reduce the data volume for needing to retrieve, and improves effectiveness of retrieval.
Further, the retrieval available call number of node 200 is respectively 3 index datas of IM-1, IM-3 and IM-4
Corresponding encrypted feature set, and according to the corresponding encrypted feature set of every index data and the corresponding encryption of data to be retrieved
Characteristic set determines the similarity degree of every index data Yu data to be retrieved.Wherein it is determined that index data and data to be retrieved
Similarity degree mode can there are many, for example, similarity calculation can be carried out based on machine learning algorithm, alternatively, can be with
Based on the similarity degree of Euler's distance algorithm computation index data and data to be retrieved, specifically it is not construed as limiting.To determine call number
For the index data of IM-1 and the similarity degree of data to be retrieved, in one possible implementation, it can obtain respectively
The index data and the corresponding first encrypted feature value of data to be retrieved and the second encrypted feature value that call number is IM-1 are taken, due to
First encrypted feature value can be used for characterizing the characteristic dimension of image, therefore can be by judging call number for the index number of IM-1
It is indexed according to whether the dimension of corresponding first encrypted feature value corresponding first encrypted feature value with data to be retrieved is identical determining
Number for IM-1 index data it is whether identical as the characteristic dimension of data to be retrieved.If call number be IM-1 index data with to
The characteristic dimension for retrieving data is different, then can determine the similarity degree of the index data that call number is IM-1 and data to be retrieved
It is 0；If call number is that the index data of IM-1 is identical as the characteristic dimension of data to be retrieved, call number, which can be calculated, is
The squared differences of the corresponding second encrypted feature value of the index data of IM-1 and the corresponding second encrypted feature value of data to be retrieved
And value, squared differences and be worth bigger, illustrate that index data that call number is IM-1 and the similarity degrees of data to be retrieved are got over
It is small, squared differences and be worth it is smaller, illustrate call number be IM-1 index data and data to be retrieved similarity degree it is bigger.
In the embodiment of the present invention, by the above process, retrieval node 200 can be calculated call number be respectively IM-1,
The similarity degree of 3 index datas and data to be retrieved of IM-3 and IM-4.In one example, retrieval node 200 can be from
One or more target for being greater than the first preset threshold with the similarity degree of data to be retrieved is chosen in this 3 index datas to index
Data；For example, the similarity degree of index data and data to be retrieved that call number is IM-1 is 50, call number is the index of IM-3
The similarity degree of data and data to be retrieved is 90, and the index data that call number is IM-4 and the similarity degree of data to be retrieved are
80, if the first preset threshold is 85, target index data may include the index data that call number is IM-3.Show at another
In example, retrieval node 200 can be ranked up this 3 index datas according to the sequence of similarity degree from big to small, Jin Erke
To select T index data in the top as target index data；For example, target index data can wrap if T is 2
Include the index data that call number is IM-3 and the index data that call number is IM-4.
In the embodiment of the present invention, data sharing and data retrieval process, Ke Yiwu are executed by using the characteristic value of data
Source data need to be obtained, the characteristic value of data greatly reduces compared to data volume for source data, so that data sharing sum number
It is less according to data volume needed for retrieval, improve data sharing and data effectiveness of retrieval；And at least one source data characteristic value
It can be used for characterizing at least one source data journey similar to data to be retrieved with the similarity degree of the characteristic value of data to be retrieved
Degree, so as to improve the accuracy of retrieval.
Step 303, target index data is sent to first node.
In one possible implementation, it if target index data is the index data that call number is IM-3, retrieves
The available call number of node 200 is the corresponding address of index data of IM-3, and then can will be by intelligent contract by the ground
Location is sent to first node 300；Correspondingly, first node 300 can be accessed by the address and be corresponded to after receiving the address
Link, obtain source data.
In one example, intelligent contract can also be to call number before the address is sent to first node 300
The index data of IM-3 is verified, for example, the search result that intelligent contract can be provided based on retrieval node 200 (indexes
Number index data for being IM-3) and the secondary similarity calculation of data to be retrieved progress, if secondary similarity be calculated it is similar
