As shown in Fig. 2 this method includes operation S201~S203.
In operation S201, user's request is received, user asks the identity data for including user.
According to the embodiment of the present disclosure, user's request for example can be the access request of user, for example, user asks to access purchase
Thing website, social network sites, gaming platform or search platform etc..
Include the identity data of user in user's request, identity data for example can be the character string of random length, example
The user name (ID) of user or the client address of user can such as be included.In the disclosed embodiments, it is different to use
The identity data at family is different, i.e. the corresponding identity data of a user.
For example, the user's request received can include：User A (the entitled Aa123 of user user) requests access Jingdone district
" Jingdone district 618 promotees greatly commodity " relevant information.In another example the user's request received can also include：User's B (user names
For Bb123 user) ask to access the relevant information on " Beijing weather forecast " of Baidu.
In operation S202, judge that identity data whether there is in Bloom filter, wherein, Bloom filter includes closing
The identity data of the user of method.
According to the embodiment of the present disclosure, Bloom filter for example can be a binary vector and a series of Random Maps letters
Number, it can be used for one element of retrieval whether in a set.For example, element can be the body of the user of currently transmitted request
Part data, set can be the set of the identity data of legal user, and it is legal for example to include this in Bloom filter
The set of the identity data of user, then Bloom filter can be used for retrieving the user of currently transmitted request identity data whether
In the set of the identity data of legal user.If in the presence of, then it represents that the user of currently transmitted request is validated user, no
Then, the user of currently transmitted request is disabled user.
In the disclosed embodiments, legal user for example can be no illegal operation record or rare illegal operation
The user of record, illegal operation are recorded such as can be frequently brush single act.It is appreciated that the disclosure does not limit legal use
Family and the specific determination methods of disabled user, those skilled in the art can be according to actual conditions to legal user and illegal
User is defined.
According to the embodiment of the present disclosure, following operation can be included in Bloom filter by judging that identity data whether there is：
(1) identity data is handled, obtains at least one mapping data.
According to the embodiment of the present disclosure, identity data is handled, such as can be by a series of in Bloom filter
Random mapping function is handled, and obtains at least one mapping data.
For example, a series of random mapping functions for example can include Message Digest 5 MD series (for example, MD2, MD3,
MD4, MD5 etc.), SHA SHA serial (for example, SHA-1, SHA-256, SHA-384 etc.), Hash operation message authentication
One or several kinds in the code hash function such as HMAC or Advanced Encryption Standard AES.
For example, the processing that user A identity data can pass through MD5 algorithms obtains mapping data A1, calculated by SHA-256
The processing of method obtains mapping data A2, obtains mapping data A3 by the processing of aes algorithm, then an identity data is at
Reason, obtain corresponding 3 mappings data.
It is appreciated that the example above is only disclosure exemplary embodiment, the disclosure does not limit to be carried out to identity data
The type function of processing, the number of function used in being handled identity data is not limited yet, those skilled in the art can
The processing is set with the actual conditions such as quantity of the version of Bloom filter or user used in.
(2) position data corresponding to each mapping data are determined, position data include the first numerical value and second value, the first numerical value
Characterize identity data to be present in Bloom filter, second value characterizes identity data and is not present in Bloom filter.
According to the embodiment of the present disclosure, because Bloom filter can include a very long binary vector, in the grand mistake of cloth
During filter is built, the identity data of each legal user can be input in Bloom filter, then according to cloth
Multiple mapping functions in grand filter are handled, and obtain multiple mapping data, then by two corresponding to multiple mapping data
The position data of the position of system vector are set to the first value (for example, putting 1).
For example, the binary vector length in Bloom filter can be 000~999,1000 units can be placed
According to, and the original state of 1000 bit data is for example all second value (for example, setting to 0).User A mapping data are A1, A2
And A3, then when building Bloom filter, the position data of the position (such as the 12nd) of binary vector corresponding to A1 are set to
1, the position data of the position (such as the 50th) of binary vector corresponding to A2 are set to 1, by binary vector corresponding to A3
The position data of position (such as the 100th) are set to 1.User B mapping data are B1, B2 and B3, then in structure Bloom filter
When, the position data of the position (such as the 12nd) of binary vector corresponding to B1 are set to 1, by binary vector corresponding to B2
The position data of position (such as the 45th) are set to 1, by the position data of the position (such as the 500th) of binary vector corresponding to B3
It is set to 1.Similarly, the identity data of each legal user recorded in Bloom filter by the above method.Can be with
Understanding, the example above is only that help understands, the disclosure does not limit the form and digit of the binary vector in Bloom filter, this
Art personnel can set according to actual conditions.
It is appreciated that the first numerical value and second value of embodiment of the present disclosure contraposition data are not specifically limited, such as the
One numerical value can be 1, and second value can be 0；Or first numerical value can be 0, second value can be 1, art technology
Personnel can set according to actual conditions to the concrete numerical value of the first numerical value and second value.
According to the embodiment of the present disclosure, after the identity data of user of currently transmitted request is received, to the identity data
Handled, obtain at least one mapping data, it is determined that the position data (example of the position of binary vector corresponding to mapping data
Such as, the position data for determining relevant position are 0 or 1).
(3) when position data corresponding to each mapping data are the first numerical value, identity data is present in Bloom filter
In.
According to the embodiment of the present disclosure, when position data corresponding to each mapping data are the first numerical value, then it represents that in structure
When building Bloom filter, the identity data as legal identity data input into Bloom filter, therefore, the identity data
Mapping position data corresponding to data, just meeting set is the first numerical value.At this time, it is believed that the identity data is present in Bloom filter,
Belong to legal identity data.
If have in more bit datas corresponding to multiple mapping data not for the position data of the first numerical value, then it represents that the identity number
According to being not present in Bloom filter, belong to illegal identity data.
For example, user A mapping data are A1, A2 and A3, if those corresponding position data of mapping data are the first number
It is worth (for example, 1), then it represents that user A identity data is present in Bloom filter, belongs to legal identity data.User C's
It is C1, C2 and C3 to map data, if position data corresponding to C1 are the second data (for example, 0), then it represents that user C identity data
It is not present in Bloom filter, belongs to illegal identity data.
In the embodiment of the present disclosure, identity data is handled using multiple mapping functions, obtains multiple mapping data, and
It is the first numerical value by data equal set in position corresponding to multiple mapping data, the degree of accuracy of authentication can be improved, effectively kept away
Multiple identity datas are exempted from and have corresponded to same map data, the problem of so as to cause authentication inaccuracy.
In operation S203, the user's acquisition request dependency number for the user being present according to identity data in Bloom filter
According to.
In the disclosed embodiments, if the identity data of user is present in Bloom filter, then it represents that the user is conjunction
The user of method, receives the request of validated user, and according to the related data of its acquisition request to feed back to the user.If user
Identity data be not present in Bloom filter, then it represents that the user is illegal user, for example, can not be to disabled user
Request handled.
For example, receive user's request：User A (the entitled Aa123 of user user) requests access the " Jingdone district 618 in Jingdone district
The relevant information of big rush commodity ".Empirical tests, if user A identity data (for example, Aa123) is present in Bloom filter,
Asked in response to the user, obtain the relevant information of " Jingdone district 618 promotees greatly commodity ", feed back and show user A.If user A
Identity data be not present in Bloom filter, then do not obtain relevant information, mitigate the pressure of background server and database.
The embodiment of the present disclosure stores the identity data of legal user by using Bloom filter, it is not necessary to directly records
The identity data of each validated user, it is possible to reduce memory space, reduce the internal memory that the identity data of legal user takes
Space or disk space.
According to the embodiment of the present disclosure, at least one mapping function is provided with Bloom filter, can be by an identity number
According to multiple mapping data and position data corresponding with multiple mapping data are corresponded to, the degree of accuracy of verification can be improved, effectively
Avoid multiple identity datas and correspond to same map data, the problem of so as to cause authentication inaccuracy.
Also, the embodiment of the present disclosure carries out legal checking by Bloom filter to user identity, if user identity is legal,
Then respond the request of the user, if user identity is illegal, it does not asked to handle, can mitigate background server and
The pressure of database.
Fig. 3 diagrammatically illustrates the flow chart for the processing method asked according to the user of another embodiment of the disclosure.
As shown in figure 3, this method includes S201, S203 and S301~S302.Wherein, operate S201 and operation S203 and
The method that above-mentioned reference chart 2 describes is same or like, will not be repeated here.
In operation S301, judge that identity data whether there is in blacklist, blacklist includes being present in the grand filtering of cloth
Device and the identity data of illegal user.
According to the embodiment of the present disclosure, if user A is validated user when building Bloom filter, user A mapping number
It is the first numerical value according to position data corresponding to A1, A2, A3.During the use of Bloom filter, user A is because of some operation quilts
Disabled user is defined as, then simply can not be deleted user A from Bloom filter, if for example, A1, A2, A3 is corresponding
Position data be set to second value, it is likely that the checking of other validated users can be influenceed, for example, user B mapping data
The position (such as the 12nd) of B1 and identical binary vector corresponding to user A mapping data A1, if simply that A1 is corresponding
Position data be set to second value, it is clear that have impact on user B legitimacy.
Therefore, the embodiment of the present disclosure provides a blacklist, can include being present in Bloom filter in blacklist,
But current identity is the identity data of illegal user, to solve the problems, such as that Bloom filter is not supported simply to delete.
In operation S302, when identity data is not present in blacklist, judge that identity data whether there is in the grand mistake of cloth
In filter.
In the disclosed embodiments, when receive user request when, by determine the user user identity whether there is in
In blacklist, if being present in blacklist, then it represents that the user is disabled user, then can not be to the request of the user at
Reason, otherwise, judge that the identity data of the user whether there is in Bloom filter.
If the identity of the user is present in Bloom filter, then it represents that the user is legal user, can perform behaviour
Make S203, otherwise it is assumed that the user is illegal user, then the request not to the user is handled.
In the disclosed embodiments, when asking to carry out legitimacy verifies to user using Bloom filter, due to using
During, illegal user is likely to occur in Bloom filter, and can not be direct to the illegal user in Bloom filter
Delete, the identity data for the illegal user that now will be present in Bloom filter is put into blacklist, solves the grand mistake of cloth
The problem of can not directly being deleted in filter, so as to improve the degree of accuracy of verification and efficiency.
The method that the embodiment of the present disclosure additionally provides renewal Bloom filter, wherein, renewal Bloom filter includes：It will close
The identity data of method is added in Bloom filter；And/or illegal identity data is deleted from Bloom filter.
Specifically, Fig. 4 diagrammatically illustrates is added to the grand mistake of cloth according to the embodiment of the present disclosure by legal identity data
The flow chart of the method for filter.
As shown in figure 4, the method legal identity data being added in Bloom filter includes S401~S404.
In operation S401, judge that legal identity data whether there is in blacklist.
New legal identity data for example can be that new user's registration produces, or can be that disabled user is converted into conjunction
Method user etc..
According to the embodiment of the present disclosure, when there is new legal user, first determine whether, whether the new legal user
It is present in blacklist, if there is in blacklist, then it represents that the user is validated user when building Bloom filter, afterwards again
Disabled user is converted into be added in blacklist.That is, the new legal identity data is that disabled user is converted into validated user.
In operation S402, when legal identity data is present in blacklist, legal identity is deleted from blacklist
Data.
According to the embodiment of the present disclosure, if legal identity data is present in blacklist, then it represents that the identity number of the user
According to also being stored in Bloom filter, now, the identity data of the user need to only be deleted from blacklist.
When receiving the request of the legal user, it is first determined the user is not present in blacklist, it is then determined that
The user is present in Bloom filter, then it is legal user to prove the user, and it can be asked to respond.
In operation S403, when legal identity data is not present in blacklist, judge that the legal identity data is
It is no to be present in Bloom filter.
When the legal identity data is not present in blacklist, the user is probably to be constantly in legal state, or
The user is probably legal identity new caused by new user's registration, now, judge the user identity data whether there is in
In Bloom filter.
