When asking, by first message digest algorithm, the corresponding forensic data of Data Identification that acquisition request is carried is encrypted, obtained
To the cryptographic Hash of the forensic data.
S109：Evidence obtaining server is encrypted to the cryptographic Hash and is obtained the second numeral and refer to by the second Message Digest 5
Line.
In the embodiment of the present invention, evidence obtaining server is entered by the second Message Digest 5, the cryptographic Hash to the forensic data
Row encryption obtains the second digital finger-print.
S110：The Data Identification that second digital finger-print and acquisition request are carried is sent to verification service by evidence obtaining server
Device.
S111：Verification server searches the Data Identification corresponding first in the digital fingerprint data storehouse of verification server
Digital finger-print, and first digital finger-print and the second digital finger-print are compared, obtain comparative result.
In the embodiment of the present invention, verification server is according to corresponding first number of Data Identification inquiry that acquisition request is carried
Word fingerprint, when first digital finger-print is inquired, first digital finger-print and the second digital finger-print is compared, if first
Digital finger-print and the second digital finger-print are identical, then verifying server can determine to be proved to be successful；If first digital finger-print and
Two digital finger-prints are differed, then verifying server can determine that checking is unsuccessful.
S112：The comparative result that verification server will be obtained is sent to evidence obtaining server.
If comparative result is used to indicate the first digital finger-print and the second digital finger-print identical, S113 is performed；If comparing knot
Fruit is used to indicate the first digital finger-print and the second digital finger-print to differ, then perform S114.
In the embodiment of the present invention, if the result that verification server is compared to the first digital finger-print and the second digital finger-print
It is identical, then after server of collecting evidence receives the comparative result, by the corresponding forensic data of the Data Identification feed back to this second
Client.If verification server is differed to the result that the first digital finger-print and the second digital finger-print are compared, evidence obtaining clothes
Business device is received after the comparative result, be will be prompted to feedback of the information and is given second client, and the prompt message is for pointing out user
Authentication failed.
S113：The corresponding forensic data of the Data Identification is fed back to second client by evidence obtaining server.
When the first digital finger-print and identical the second digital finger-print, evidence obtaining server can determine the first digital finger-print correspondence
Forensic data and the corresponding forensic data of the second digital finger-print it is identical, and then collect evidence server can determine evidence obtaining server in
The forensic data that second client of storage is asked is not distorted by third party, and evidence obtaining server may insure the forensic data
Authenticity, and then the corresponding forensic data of the Data Identification is fed back into second client, so that the second client is to user
Show the corresponding forensic data of the Data Identification.
S114：Evidence obtaining server will be prompted to feedback of the information and give second client.
In the embodiment of the present invention, the first client can send data acquisition instructions and give evidence obtaining server, when evidence obtaining is serviced
When device receives the data acquisition instructions, the forensic data collected when user accesses webpage by the first client is obtained, with
And the Data Identification of the forensic data, by first message digest algorithm, the forensic data is encrypted, obtain the evidence obtaining number
According to cryptographic Hash, by the second Message Digest 5, the cryptographic Hash is encrypted, the first numeral for obtaining the forensic data refers to
Line, and the first digital finger-print and Data Identification are sent to verification server, verification server generate the first digital finger-print and
The corresponding relation of Data Identification, and the first digital finger-print and its corresponding Data Identification are stored, the second client sends to obtain and asks
Ask and give evidence obtaining server, evidence obtaining server is by first message digest algorithm, the Data Identification correspondence carried to acquisition request
Forensic data carry out double-encryption and obtain the second digital finger-print, and data that the second digital finger-print and acquisition request are carried
Mark is sent to verification server, and be compared for first digital finger-print and the second digital finger-print, will obtain by verification server
Comparative result be sent to evidence obtaining server, the comparative result that evidence obtaining server will be obtained feeds back to second client.It can be seen that,
The data processing method of the embodiment of the present invention can avoid data from being tampered, and improve the security of data.
