It is placed in user side, it is also possible to be arranged in network equipment.The method comprises the steps:
Step S101, when the linking sources that user side downloads data is converted to first object link,
The download information of linking sources in Statistics table, to generate statistical result；
In information table in the embodiment of the present invention, record has user side to download the historical information of data,
Here user side is not limited to a user side, can be multiple different user sides, note
The historical information of download data of record may be collectively referred to as download information, this download information concrete
Content can be arranged flexibly according to reality application, such as, may include that in download information
Linking sources, Object linking, download time etc., based on this, this information table can use as follows
Form shown in table 1:
Table 1
| Linking sources | Object linking | Download time |
| Link A1 | Link B1 | 2 times |
| Link A1 | Link B2 | 10 times |
Wherein, linking A1 in Article 1 record is the linking sources that user side is clicked on, and links B1
For redirecting the Object linking that (or conversion) arrives after clickthrough A1, count on before 2 feelings the pulse with the finger-tip
Linking sources be link A1, Object linking is that link B1 is downloaded the number of times of data.With
Reason, the implication of each list item and the implication phase of corresponding list item in Article 1 record in Article 2 record
With, repeat no more here.
Certainly, above-mentioned download information can also include: linking sources, Object linking, download
Number of times and the eigenvalue of download data corresponding to Object linking, based on this, this information table
Can be to use form as shown in table 2 below:
Table 2
| Linking sources | Object linking | Download time | Eigenvalue |
| Link A1 | Link B1 | 2 times | A1 |
| Link A1 | Link B2 | 10 times | A2 |
Wherein, linking A1 in Article 1 record is the linking sources that user side is clicked on, and links B1
For redirecting the Object linking that (or conversion) arrives after clickthrough A1, count on before 2 feelings the pulse with the finger-tip
Linking sources be link A1, Object linking is that link B1 is downloaded the number of times of data, A1
Referring to that linking sources is link A1, Object linking is that the eigenvalue of the data that link B1 downloads to is
A1.In like manner, the implication of each list item and corresponding list item in Article 1 record in Article 2 record
Implication is identical, repeats no more here.
In the present embodiment, after user operation user side clicks on linking sources, first can be produced
Object linking, first object link is also to prepare to provide the link downloading data to user.
Before being downloaded by first object link, need to know that first object link is true mesh
Mark link or pseudo-Object linking, under can improving by the operation of corresponding download process
The success rate carried.
Thus, when the linking sources that user side downloads data is converted to first object link, this
Embodiment performs the download information of linking sources, Jin Ersheng in step S101, i.e. Statistics table
Become statistical result.Wherein the download information of linking sources is it may be that multiple terminal clicks on linking sources
Produced download information, such as the download time of linking sources, access times etc..In information table
Information can be that local system is entered in information table in advance, it is also possible to by other system
It is entered in information table, then got by local system.
Step S102, according to statistical result, determines and links the target being associated with first object
Statistics ratio shared by link；
When implementing, linking the Object linking being associated with first object can be first
Object linking self, it is also possible to be to be connected to other of close similarity with first object chain link,
As a example by the eigenvalue of the data downloaded to, the eigenvalue and of data that can will download to
The same or analogous link of eigenvalue of the data that one Object linking downloads to as with the first mesh
The mark Object linking that is associated of link, and eigenvalue is the most similar can pass through two eigenvalues
Similarity weigh.Based on this, above-mentioned link the object chain being associated with first object
Connect the address that can be understood as linking with first object identical, or link with first object
Download the download link that content is identical/similar.
Statistics ratio in step S102 can be understood as linking with first object and is associated
The ratio that Object linking download time/number of clicks is overall with statistical result.Such as linking sources A altogether
Clicked (download) 500 times (statistical result), has been produced after linking sources A is clicked
Having given birth to 500 Object linkings, wherein, the number of times producing Object linking B is 450, produces
The number of times of Object linking C is 50.It is B when linking the Object linking being associated with first object
During link, then the statistics ratio shared by the Object linking being associated that links with first object is
450/500, i.e. statistics ratio is 9/10.Statistics ratio it is also understood that as in certain time period,
First object link (click on linking sources produced by the first object link) quantity produced with
The ratio of the clicked quantity of linking sources.
It should be noted that some time period is probably downloads the time period occurred frequently kidnapped, because of
This, can not record the download information in time period in above-mentioned information table, to ensure system
The effectiveness of meter.
Step S103, is downloaded process according to the size of statistics ratio to first object link
Operation.
After determining statistics ratio, just can be come according to statistics ratio by step S103
The size of example carries out corresponding download process and operates.It should be noted that in actual life,
Although downloading the phenomenon kidnapped to happen occasionally, but, relative to the number of times normally downloaded
For, occur that the number of times downloading abduction phenomenon is less.Therefore, by under a large amount of statistics
Carry Object linking produced by linking sources, obtain linking relative to the selected objective target of linking sources
(repeatedly in the produced Object linking of loading source link, produce the link that number of times is most), just
Can determine whether this time loading source link produced first object link is true object chain
Connect, when first object link is true Object linking when, user side just can be allowed to continue
It is downloaded by first object link；When first object link is pseudo-Object linking when,
Can be by proxy server (the safety height using proxy server to be downloaded preset
In the safety that ordinary terminal is downloaded) it is downloaded by linking sources, or logical
The terminal crossing other is downloaded again, it is also possible to stop being downloaded by first object link.
The said method of the present embodiment uses the mode of data statistics, and in prior art
Owing to cannot distinguish whether user side is downloaded abduction, and then cause user side to be downloaded
Data do not meet its wish and compare, its by added up in information table with first object
(first object link is that user side passes through to download to the Object linking quantity that link is associated
The linking sources of data and change out), and try to achieve this number statistics of variables ratio, and
Size according to this statistics ratio is carried out the corresponding process that is downloaded and is operated, thus ensures
The data fit that user side is downloaded its download wish, improve and download the accurate of data
Property, and then improve the Experience Degree of user.
Concrete, in step S103, it is also possible to hold according to varying in size of ratio of statistics
The download process operation that row is different.As (time between 0.5-0.6, permissible in above-mentioned statistics ratio
It is downloaded by first object link, then carries out authenticity verification to downloading the file obtained；
When statistics ratio is between 0.6-0.8, can be by the standby terminal loading source chain again preset
Connect, if the address that the address of obtained link links with first object is identical, the most permissible
Think that first object link is true Object linking, the most just can normally download；Statistics ratio exists
Time between 0.8-1, then it is fair to consider that first object is linked as true Object linking, Ke Yizhi
Tap into row down operation.
It should be noted that for the workload reducing system, improve running efficiency of system,
The judgement of data can be downloaded before performing step S101-step S103.Specifically sentence
Disconnected flow process is as follows: (1) obtains the corresponding filename downloading data of first object link；
(2) judge whether the download data corresponding to first object link are to use according to filename
The data that family end is capable of identify that are (such as the application program apk of android, the application program of Microsoft
Exe), if it is, perform step S101-step S103.
Certainly, step (2) can also be replaced by following steps: (2 ') are sentenced according to filename
Whether the download data corresponding to disconnected first object link are that user side may be kidnapped by high frequency
Data.Wherein, in step (2 '), the number of times of abduction can be downloaded by data and unite
Count out which kind of data and be easily downloaded abduction, namely know the number may kidnapped by high frequency
According to.
Before performing step S103, it is also possible to first carry out the judgement of a step total amount, the most just
The download information being linking sources in information table is the most abundant, when under the linking sources in information table
The when that the quantity of information carrying breath being fewer, then reference value (credibility of reference) is relatively low.
Therefore can first judge that the quantity of the download information of linking sources was before performing step S103
No reaching predetermined quantity, if reached, then performing step S103.
Concrete, as in figure 2 it is shown, step S101, the download of linking sources in Statistics table
Information, comprises the steps: generating statistical result
Step S1011, in Statistics table, record has the download time summation of linking sources, note
Being the first statistical value, wherein, the download information in information table every record includes: linking sources,
Object linking and download time；
Step S1012, is recorded as linking sources in Statistics table, and Object linking is first
The download time of Object linking, is designated as the second statistical value.
Wherein, in step S1011, specifically illustrate the first statistical value in statistical result
It it is the download time summation of linking sources.Certainly, linking sources download time total of indication herein
With it may be that the download time summation of linking sources in the range of certain time.If certain sky 8
The summation of-21 linking sources download time of point.Certainly, when the download time summation of linking sources
When being the download time summation in some time range, in step S1012, provided
Second statistical value also should be to be recorded as linking sources in this time range, and Object linking is
The download time summation of one Object linking.In such cases, can directly look in information table
Look for the Object linking that linking sources is corresponding be first object link occurrence number (or download time
Number), and using this number of times as the second statistical value.Then, in step S102, pass through step
S1011 and step S1012 confirm the first statistical value and the second statistical value, just can calculate
Statistics ratio, concrete calculation is: the second statistical value/the first statistical value.By this side
Formula can simply determine statistical result, provides reliable data to protect for subsequent operation
Barrier.
In addition to this mode that step S1011 and step S1012 are provided, also have as follows
The another kind that step is provided downloads the situation that content is similar, namely as it is shown on figure 3, walk
The download information of linking sources in rapid S101, i.e. Statistics table, includes generating statistical result
Following steps:
Step S1013, in Statistics table, record has the download time summation of linking sources, note
Being the first statistical value, wherein, the download information in information table every record includes: linking sources,
Object linking and download time, and Object linking characteristic of correspondence value；
Step S1014, obtains the First Eigenvalue of download data corresponding to first object link；
Step S1015, is recorded as linking sources in Statistics table, and eigenvalue and first special
The similarity of value indicative, more than the download time of the first setting threshold value, is designated as the second statistical value.
Wherein, step S1013 is similar with step S1011, is all it needs to be determined that linking sources
The summation of download time, certainly, herein the linking sources download time of indication summation it may be that
The download time summation of the linking sources in the range of certain time.Unlike step S1011,
Download information in step S1013 also includes Object linking characteristic of correspondence value.This feature
Value can be understood as distinguishing the identification code of different target link, and certainly, this feature value is
Relevant to Object linking, as downloaded data (downloading data produced by Object linking)
Length, content (digital label, the download data place number such as download data of download data
According to bag packet header), download data installation kit name (such as the Package Name of APK file),
The cryptographic Hash downloading data content can also be calculated by hash algorithm, and by this Hash
Value is as eigenvalue.
In step S1014, it is thus necessary to determine that the of the download data corresponding to first object link
One eigenvalue, the First Eigenvalue herein includes downloading the length of data, downloading data equally
Content, download data installation kit name etc..
In step S1015, require to look up, be recorded as linking sources, and eigenvalue and
The similarity of one eigenvalue more than first setting threshold value download time, and using this number of times as
Second statistical value.This place statistics be the download content linked with first object identical or
The number of downloads of close Object linking.Then, in step S102, by step S1013-
Step S1015 confirms the first statistical value and the second statistical value, just can counting statistics ratio,
Concrete calculation is: the second statistical value/the first statistical value.Can compare in this way
Statistical result is precisely determined, provides reliable Data safeguard for subsequent operation.
Concrete, carrying out data download when, can be potentially encountered download content and adjust
Whole situation, as the Object linking corresponding to linking sources is adjusted by Virtual network operator.Source
The download content of the Object linking A that link (latest edition of certain operating file) is the most corresponding
It is the operating file of 2.23 versions, after adjustment, under the Object linking B corresponding to linking sources
Carry the operating file that content is 2.24 versions.It is of course also possible to be that Virtual network operator does not changes
Object linking corresponding to linking sources, and change and specifically download content corresponding to Object linking.
It may also be that Virtual network operator is in order to control the visit capacity of certain Object linking, it is provided that give and use
End multiple Object linking in family carries out selecting that (purpose is the visit capacity mistake preventing certain Object linking
Greatly, and the speed of service of server is caused to decline), this download corresponding to multiple Object linkings
Content is all identical.As can be seen here, determined by step S1013-step S1015 first
First statistics determined by statistical value and the second statistical value and step S1011 and step S1012
Value is compared with the second statistical value, and the former accuracy is higher, is right with first object link institute
The download content answered is according to carrying out that add up rather than that statistics first object links address
The number of times being downloaded.
Further, in step S1013 the eigenvalue of indication can be download data size,
Download data place packet bag name (such as the Package Name of APK file), under
Carry data place packet packet header, download data particular content etc., it is also possible to be by
The particular content downloading data is calculated by the hash algorithm preset, to generate cryptographic Hash,
And using this cryptographic Hash as eigenvalue.
When eigenvalue has multiple, adding up the second statistical value when, can be with statistical information
Table is recorded as linking sources, and every kind of eigenvalue all with the similarity of the First Eigenvalue more than the
One download time setting threshold value, is designated as the second statistical value.I.e., only every kind eigenvalue is equal
Meet the requirements (all similar with the First Eigenvalue of corresponding kind) time, just this record can be united
It is calculated as the ingredient of the second statistical value.Can also be the similarity first calculating every kind of eigenvalue,
Again the similarity calculated is averaging, further according to average similarity whether more than the preset
One sets threshold value, and then completes the statistics of the second statistical value.
It should be noted that add up first whether by step S1011 and step S1012
Value and the second statistical value are added up, or by step S1013 and step S1014 to the
One statistical value and the second statistical value are added up, and form the first statistical value and the second statistical value
Multiple records are preferably the record of the terminal execution download action of different IP addresses.Generally, under
The probability carrying abduction generation is the highest, it is likely that some (or in certain little scope)
The terminal of IP address is in the state of being held as a hostage all the time, therefore, according to different multiple in IP address
Terminal performs the record of download behavior and adds up, and can effectively improve the first statistical value and the
The credibility of two statistical values, and then it is effective to be downloaded process operation offer for step S103
Reference.
Concrete, step S102, determine and link the Object linking institute being associated with first object
The statistics ratio accounted for comprises the steps: that setting links the object chain being associated with first object
Connecing shared statistics ratio is that the second statistical value is divided by the first statistical value.Second statistical value is removed
Using the result of the first statistical value as statistics ratio, it is possible to relatively simple acquisition statistics ratio
Numerical value.
Specifically, the purpose of user side is the data content corresponding to the link of correct loading source.
Therefore, step S103, according to the size of statistics ratio, first object link is downloaded place
Reason operation comprises the steps:
S1031, it is judged that whether statistics ratio is more than the second setting threshold value, if being judged as YES,
Then perform step S1032；
S1032, it is allowed to user side downloads data in first object link.
Namely when the ratio of statistics more than the second setting threshold value when, it is allowed to user side is the
One Object linking downloads data.During concrete operations, the source of data can be downloaded according to user side
Link is converted to the place, IP address of the time period at place, user side during first object link
Region suitably adjusts the size of the second setting threshold value.
Step S1031, except situation about being judged as YES, there is also its situation about being judged as NO,
Namely step S103, is downloaded place according to the size of statistics ratio to first object link
Reason operation also includes:
If statistics ratio is less than the second setting threshold value (step S1031 is judged as NO), then
Perform step S1033, according to the download information of linking sources of record in information table, select the
Two Object linkings download the link of data as user side.
Wherein, the second Object linking can be that Object linking set in advance is (such as agency service
In device, or other-end, the Object linking corresponding with linking sources), it is also possible to it is according to letter
In breath table, linking sources, Object linking and the download time of record, select the download of Object linking
What number of times was most links the link downloading data as user side.
In actually used, after clicking on certain linking sources such as user side, produced object chain
Scooping out is http: // download .rar, but after occurring to download abduction, the address of Object linking is then
Http: // 1Q2W3E4R5T6Y7U8I9O0P1Z2X3C4V5B/ download .rar may be become,
And then result in user side and fetch not by the real goal chain corresponding to linking sources and get
Download data, but the object chain distorted by a process is fetched and gets download data
's.
For the first statistical value in said method and the acquisition mode of the second statistical value, this
Bright embodiment provides the example of following two kinds of anti-hijacking methods downloaded in data procedures respectively.
Example 1
This example is by checking that linking sources and object chain fetch detecting and kidnap, and detailed process is as follows:
1. client (user side) clickthrough A (linking sources A) creates download link B
(Object linking B).
2., after client starts download link B, download link B can return link correspondence
Filename N (as download link B does not returns the filename that link is corresponding, then can pass through it
His mode obtains the filename of correspondence)；
If 3. filename N is the specific extension name of a certain class (the application journey such as android
Sequence apk, the application program exe of Microsoft), link A and link B can be sent by client
To file verification server；
4. being provided with linking sources information table (Source) in file verification server, every a line includes
Content { linking sources, Object linking, number of times }, after taking linking sources A and Object linking B,
Searching in linking sources table, the inside is the information of A without linking sources, then return checking
Successful client of giving, at this time client continuation download+, file verification server inserts simultaneously
One record linking sources A, Object linking B, number of times 1} to Source, flow process terminates,
If linking sources table exists the information that linking sources is A, then carry out step 5.
5. whether file verification server inspection oneself linking sources information table exists Object linking
For B, and linking sources is the content of A, if there is no then inserting a record { source chain
Meeting A, Object linking B, number of times is the record of 1}；
6. calculating the number of times X that Object linking is corresponding, computational methods are for linking sources information table institute
The active A that is linked as, and Object linking is the number of times of B, and specific coding is as follows；
{ select sum (number of times) from source where linking sources=A and Object linking
=B}；
Calculating the number of times Y that linking sources is corresponding, computational methods are active for linking sources information table
Being linked as the number of times sum of A, specific coding is as follows:
{ selecdt sum (number of times) from Source where linking sources=A；}；
If number of times Y is more than some, and X/ several Y of number of times are less than particular value, then
Return authentication failed is to client, and in linking sources table, linking sources is whole notes of A
In record, the Object linking B' corresponding to record of number of times maximum sends back to client, jumps afterwards
Forward step 7 to；Otherwise returning is proved to be successful to client, jumps to 8；
If after 7. client receives the information of authentication failed, then cancel current to link
The download of B, if B ' is not equal to A, initiates the download to Object linking B' the most again, and
Terminate current process；If A equals B ', enter specific flow processing, flow process terminates.
If 8. client receives the information being proved to be successful, then continuing to download, flow process terminates.
Wherein, the specific flow process in step 7 can be prompting failed download to user, and
Terminate downloading；Can also be that link A is sent to intermediate proxy server, and by centre
Link A is downloaded by proxy server.
Example 2

As follows:
1. client (user side) clickthrough A (linking sources A) creates download link B
(Object linking B).
2., after client starts download link B, download link B can return link correspondence
Filename N (as download link B does not returns the filename that link is corresponding, then can pass through it
His mode obtains the filename of correspondence)；
If 3. filename N is the specific extension name of a certain class (the application journey such as android
Sequence apk, the application program exe of Microsoft), link A and link B can be sent by client
To file verification server；
4. one linking sources information table (Source) of file verification server record, every a line includes
Content { linking sources, Object linking, number of times }, also record have one for Object linking mark sheet
(Target), every a line content is { Object linking, eigenvalue }；Take linking sources A and target

Content and the data content cryptographic Hash of download data, download the data content such as APK literary composition of data
The feature etc. of partial content in the Package Name of part definition, APK file；
4.2 file verification server contrast link B and B1, if identical, then insert one
{ linking sources A, Object linking B1, number of times is that 1} is to linking sources information table, insertion one to record
{ Object linking B1, feature T} is to Object linking mark sheet, if B Yu B1 is or not bar record
Deng, then jump to 4.3；
4.3 file verification servers download B, and the filename downloading content is recorded as N', with
Time file content is carried out feature extraction, the feature of extraction is T ', insert one record { source
Link A, Object linking B, number of times be 1} to linking sources information table, inserts one record { mesh
Mark link B, feature T ' to Object linking mark sheet.
5. whether file verification server inspection oneself linking sources information table exists Object linking
For B, and linking sources is the content of A, if there is no then inserting a record { source chain
Meeting A, Object linking B, number of times is the record of 1}, if there is then the number of times of record being added
1；
6. calculate the number of times X that Object linking is corresponding；Computational methods are for linking sources information table institute
The active A that is linked as, and according to the eigenvalue of the file set out under Object linking and according to mesh
The number of times sum of the record that the eigenvalue of file that sets out under mark link B is same or like:
{ select sum (number of times) from source where linking sources=A and Object linking
In (select Object linking from Target where eigenvalue=(select eigenvalue from
Target where Object linking=B)) }；
Calculating the number of times Y that linking sources is corresponding, computational methods are active for linking sources information table
It is linked as the number of times sum of A:
{ selecdt sum (number of times) from Source where linking sources=A；}
If number of times Y is more than some, and X/ several Y of number of times are less than particular value, then
Return authentication failed is to client, and in linking sources table, linking sources is whole notes of A
In record, the Object linking B' corresponding to record of number of times maximum sends back to client, after oneself
Jump to step 7；Otherwise returning is proved to be successful to client, jumps to 8；Specific coding is such as
Under,
{ select Object linking, number of times from source where linking sources=A order by
Number of times desc limit 0,1}；
If after 7. client receives the information of authentication failed, then cancel current to link
The download of B, if B ' is not equal to A, initiates the download to Object linking B' the most again, and
Terminate current process；If A equals B ', enter specific flow processing, flow process terminates.
If 8. client receives the information being proved to be successful, then continuing to download, flow process terminates.
Wherein, the specific flow process in step 7 can be prompting failed download to user, and
