According to embodiments of the present invention, a kind of large-scale data circulation method is provided, as shown in Figure 1, this method includes such asUnder step S100 to step S108:
Step S100, the ciphertext from multiple data sources is stored；
Specifically, as shown in Fig. 2, ciphertext of the storage from multiple data sources includes:
Step S200, safety caculation module stores the encrypted running data from the first data source；
Step S202, safety caculation module stores the encrypted violation data from the second data source；
Step S204, safety caculation module stores the encrypted insurance data from third data source.
First data source refers to user mobile phone and onboard system, and the second data source refers to traffic management department, third dataSource refers to insurance company；Traveling number can be collected by user mobile phone and onboard system, traffic management department, insurance companyAccording to, violation data and insurance data, and complete to calculate the safety being sent to after the encryption of above-mentioned data in safety caculation moduleArea；Calculating and data reallocation may be implemented by calculating area safely, provided safeguard for large-scale data circulation.
In some embodiments, it can also be preference, maintenance, used car data etc., the source of the unlimited fixed number evidence of the present invention,Data source can be multiple.
Step S102, it receives through the decryption key after RSA public key encryption；
Specifically, as shown in figure 3, reception includes: by the decryption key after RSA public key encryption
Step S300, pass through decryption key described in the RSA public key encryption in encrypting module；
Step S302, safety caculation module receives the encrypted decryption key.
RSA public key is preset in encrypting module, obtains the ciphertext of key by encrypting the RSA public key decryptions key, is led toNetwork sending is crossed, which is received by safety caculation module.
Step S104, the ciphertext is decrypted；
Specifically, as shown in figure 4, decrypting the ciphertext and including:
Step S400, it decrypts to obtain decryption key by RSA private key combination decipherment algorithm；
Step S402, the ciphertext is decrypted by the decryption key.
After safety caculation module receives the decryption key after the decryption, by be set in advance in decipherment algorithm therein andRSA private key, solution lock out decryption key from encrypted decryption key, and decrypts ciphertext by decryption key and obtain in original textHold.Guarantee the data safety in large-scale data circulation.
Step S106, the original text that decryption obtains is calculated according to default computation rule；
Specifically, as shown in figure 5, including: according to the original text that the calculating decryption of default computation rule obtains
Step S500, the incidence relation of the original text is determined according to preset matching rule；
Step S502, data are calculated by computation model and use report；
Step S504, the data are fed back according to associated relationship and uses report.
The association completed between decryption and data inside safety caculation module calculates.Specifically, in safety caculation moduleThe specified external input of middle storage, such as fingerprint, but the data external in safety caculation module can not directly obtain, and can only holdWhether the specific computation rule of row, such as two fingerprints of storage, match consistent.Computation rule is defined by data user's.The encryption data of multiple data sources, such as the form track of certain vehicle, violating the regulations and insurance data are stored in from three data sourcesInto safety caculation module, second-hand car trader or insurance company can obtain quotation or the guarantor of used car by default computation modelDanger quotation is not related to the output of data detail to realize, can but feed back to user's data and use report.
Step S108, calculated result is exported in one or more data sources.
User mobile phone, onboard system, traffic control system, insurance company management system interface in output calculate knotFruit is not carried out data dealing directly, but is calculated and carried out indirectly based on data safety to realize the application and circulation of dataThe circulation of data equity, final application value dimension complete data to the closed loop applied in the service of data holder itself.
Preferably, as shown in fig. 6, after one or more data source output calculated results further include:
Step S600, original text, ciphertext, decryption key and calculated result are destroyed.
After calculated result generation, original text that safety caculation module auto-destruct stores in the database, ciphertext, decryptionKey and calculated result；Guarantee that data will not be revealed, or is illegally accessed.
It can be seen from the above description that the present invention realizes following technical effect:
In the embodiment of the present application, by the way of large-scale data circulation, by safety caculation module storage from moreThe ciphertext of a data source；It receives through the decryption key after RSA public key encryption；Decrypt the ciphertext；According to default computation ruleCalculate the original text that decryption obtains；And calculated result is exported in one or more data sources；Realize large-scale dataCirculate and prevent the side of procurement data from carrying out two time selling；Reach the point-to-point data circulation of substitution and has two time selling hiddenThe purpose of trouble to realize the technical effect for greatly promoting data circulation efficiency, and then solves point-to-point due to being only capable ofTransaction circulation, and there is also the technologies of the data circulation low efficiency that may cause of two time selling to ask by a side of procurement dataTopic.
