Browser, the various clients that cell phone application is representative；Front end is communicated by network with server-side, which can be
Gauze network or wireless network；Inside server-side, including filter layer, application layer and database, wherein if application layer includes again
Dry Applied layer interface；Filter layer is that the information filtering method that provides through the embodiment of the present invention is newly-built, meanwhile, with the filter layer
For boundary, application layer and database are referred to as back-end server in server-side, with corresponding with front end.Front end user passes through client
Various request of data are initiated, after the filter layer of server-side filters sensitive information, return to client, the embodiment of the present invention provides
Information filtering method be applied to server-side filter layer.
In one embodiment, as shown in Fig. 2, providing a kind of information filtering method, implementation process includes the following steps:
S1: non-sensitive information database is established, wherein non-sensitive information database includes sensitive field, Field Sanitization condition, with
And the mapping relations between sensitive field and Field Sanitization condition.
Specifically, an embedded database is created in filter layer, such as can be SQLite database, it is quick for storing
Feel the mapping relations between field, Field Sanitization condition, and sensitive field and Field Sanitization condition.
Wherein, it is very low to occupy resource for embedding data library, such as is applied to as in mobile phone, tablet computer embedded product
Account for the memory of several hundred K；Embedded database saves newly-built database so that it is convenient to and application program in the form of single file
Carry out connection either statically or dynamically；SQLite is a typical embedded database, it and common non-embedded database phase
Than the space occupied is very small, and different from common client-server paradigm, SQLite is the library in a process, realizes
Self-centered, serverless backup, zero configuration, businesslike SQL database engine.SQLite engine is not one independent
Process can either statically or dynamically be connected by application requirement.
In practical applications, reflecting between sensitive field, Field Sanitization condition, and sensitive field and Field Sanitization condition
The relationship of penetrating can be configured in advance by user.For example, sensitive field include but is not limited to customer name, cell-phone number,
Identification card number, home address etc..Field Sanitization condition includes but is not limited to: only retaining surname to name, shields name；To mobile phone
Numbers shielding intermediate four；Four are shielded among identification card number；Directly hide home address；All information of mask field etc..
Mapping relations between sensitive field and Field Sanitization condition can be correspondingly, such as:
Customer name in sensitive field, the only reservation surname in corresponding field filter condition shield name；
Cell-phone number in sensitive field, four among the shielding cell-phone number in corresponding field filter condition；
Identification card number in sensitive field, four among the shielding identification card number in corresponding field filter condition；
Or many-one, such as:
Customer name in sensitive field, the identification card number in cell-phone number and sensitive field in sensitive field all correspond to word
All information of mask field in section filter condition.
Mapping relations between sensitive field and Field Sanitization condition can be adjusted dynamically according to the needs of practical application.
Newly-built SQLite database is deployed in the filter or blocker in Spring frame, is equivalent in Spring
Increase a filter layer in filter or blocker in frame newly, the filter layer include newly-built SQLite database and other with
Relevant module is filtered, for realizing the information filtering function of the present embodiment, thus instead of original reality in each Applied layer interface
Existing filtering function.Wherein, Spring is the design level frame an of open source code, is the Java exploitation an of lightweight
Frame, what he solved is the loose coupling problem of Business Logic He other each layers.For large-scale Web application system, usually first
Spring is deployed on server, then further according to the needs of practical application, secondary development is done on Spring.It does so and fills
Divide the existing interface that Spring frame is utilized, avoid the development of simple repeatability, and can quickly develop and be suitble to itself
The application that business needs.By taking Fig. 1 as an example, position of the position of Spring frame between front end and Applied layer interface, with filter layer
It sets identical.
S2: the data that back-end server is returned by Applied layer interface are received, and data are parsed to obtain the data
In include parameter name and parameter value.
Specifically, after the item data request that client is initiated reaches the database of back-end server, each application layer is connect
The data of the Database Feedback of back-end server are returned to client by mouth, which is usually returned with fixed data format,
Be conducive to parse the data of needs.
Wherein, the data format of the fixation has JSON (JavaScript Object Notation, JS object numbered musical notation)
The data file of format, Map object, wherein JSON is a kind of data interchange format of lightweight；Map object is in Java
Collection class, it provides a kind of element storage method.
Between Applied layer interface and front end, the data that Applied layer interface returns are intercepted, are parsed, obtains and filters
Relevant information, i.e. parameter name and parameter value.
By taking certain Applied layer interface returns to " user insure master data " as an example, parameter name includes address name, age, hand
Machine number, insurance kind of insuring, total amount of insuring；Then corresponding parameter value is " Zhang San ", and " 30 ", " 13912345678 " are " omnipotent
Danger ", " 200,000 ".
Applied layer interface is customized as business needs, and different business needs, then the data that each Applied layer interface returns
It is different.For example, some business need the master data of user, then the Applied layer interface only returns to address name, age, identity card
Number, home address；Some business need to insure relevant data, then the Applied layer interface only returns to user id, insurance kind of insuring, and throw
Protect total amount.
S3: according to parameter name, inquiry and the matched target susceptibility field of the parameter name in non-sensitive information database,
And aiming field filter condition corresponding with target susceptibility field is obtained according to mapping relations.
Specifically, still by taking " user insure master data " in step S2 as an example, the parameter that parses in step s 2
Title includes address name, age, cell-phone number, insurance kind of insuring, total amount of insuring.By these parameter names one by one with local
Sensitive field in SQLite database is compared, if parameter name belongs to sensitive field, has mapping to close with sensitive field
The filter condition of system is the aiming field filter condition for the parameter name.For example, cell-phone number belongs to sensitive field, then with it is quick
Sense field " cell-phone number " has the filter condition " shielding is four intermediate " of mapping relations, is the target of shielding parameter title " cell-phone number "
Field Sanitization condition.
S4: processing is filtered to parameter value according to aiming field filter condition, obtains filtered target data.
Specifically, the aiming field filter condition got according to step S3, is filtered the parameter value of parameter name
Processing.For example, the aiming field filter condition obtained according to step S3 " shields if shielding to parameter name " cell-phone number "
Cover four intermediate ", it is the data of " 13912345678 " for cell-phone number, the centre four of cell-phone number, modification is replaced with " * " number
For " 139****5678 ".
S5: target data is returned into front end user.
Specifically, by the target data Jing Guo filtration treatment, intermediate four cell-phone numbers " 139****5678 " are such as shielded
It is returned to front end user.
In the present embodiment, in the filter or blocker of Spring frame, by Applied layer interface and front end it
Between establish a filter layer, it is unified to shield sensitive information, alleviate the development amount of each Applied layer interface, reduce code
The risk of error is convenient for unit testing and maintenance but also independence is higher between code module, reduce maintenance and management at
This；By creating a local SQLite database, sensitive information centralized management is accomplished once to configure, and each Applied layer interface is suitable
With facilitating system maintenance and upgrading.
Further, in one embodiment, non-sensitive information database further includes data mode and data filtering condition, and
Mapping relations between data mode and data filtering condition.Data mode refers to Service Period locating for an item data.Due to
The difference of locating Service Period, the data are suitable for different data filtering conditions.Data filtering condition refers to for different
For field, i.e., under a kind of data mode, there may be several fields to belong to and need to do shielding processing.
For example, the loan data of client has " application ", " in audit ", " refusal ", " in lending ", " having paid off " etc. several
Kind state.When customers' place is in " application " and " in audit " two states, lending business personnel is it can be seen that all customer datas
, i.e., the value of all fields；It but is that can't see cell-phone number, the amount of the loan when to " refusal ", " in lending ", " having paid off " state
, that is, it can't see the value under " cell-phone number ", " amount of the loan " two fields.Therefore, in " refusal ", " in lending ", " having paid off "
Under state, corresponding data filtering condition is to hide cell-phone number, hide the amount of the loan.
As shown in figure 3, being filtered processing to the parameter value according to the goal filtering condition in step S4, it is obtained
After target data after filter, and before target data is returned to front end user by step S5, information filtering method is also wrapped
Include following steps:
S21: the current state of data is obtained.
Specifically, when client initiates inquiry request, Applied layer interface is according to the type of service of request, in back-end services
The data mode of current business is inquired in device.When receiving the data that back-end server is returned by Applied layer interface
The current state of data therefrom.
S31: target data filter condition corresponding with current state is inquired in non-sensitive information database.
Specifically, the data mode obtained according to step S21, inquiry and current data state in non-sensitive information database
Matched target data filter condition.
S41: processing is filtered to parameter value according to target data filter condition, obtains filtered target data.
Specifically, the target data filter condition obtained according to step S31, that is, may know that the target data filter condition is
Which it is filtered for field.These fields are matched with the parameter name that parsing obtains, obtain needing to be filtered
Parameter value, and these parameter values are filtered according to target data filter condition, obtain target data.
In the present embodiment, further include data mode and data filtering condition and data mode in sensitive information library with
Mapping relations between data filtering condition.By combining sensitive field, Field Sanitization condition, data mode and data filtering rod
Part four elements are filtered back-end server by the data that Applied layer interface returns, can more flexible filtering sensitivity
Information.
Further, in one embodiment, back-end server is JSON format by the data that Applied layer interface returns
Data file is parsed to obtain in the data and be wrapped to back-end server by the data that Applied layer interface returns in step s 2
The parameter name and parameter value contained, specific steps include:
S6: according to the file structure of JSON format, to back-end server by the data that Applied layer interface returns carry out by
Layer recursion resolution, obtains the key-value pair for including in the data, wherein each key-value pair includes that parameter name is corresponding with the parameter
Parameter value.
Specifically, key-value pair (key-value) is common a kind of data type in software development, when being data storage most
Simple organizational form.Wherein, key (key) is the number of the data of storage；Value (value) is the data to be stored.
By taking JSON format as an example, the JSON data about loan documentation are expressed as follows:
Wherein, " customer name ", " cell-phone number ", " identification card number " and " record list " and their corresponding values are first
The key-value pair of layer；" amount of the loan ", " loan interest rate " and their corresponding values are the key-value pair of the second layer.It is to be appreciated that
For more complicated data structure, it may include many layer datas in a JSON file.Meanwhile the sensitive field for needing to filter
The different layers being possibly also present in JSON.
For the JSON data file of multilayer, key-value pair is parsed using the method that recurrence successively parses.Specifically, as schemed
Shown in 4, analyzing step are as follows:
S61: traversing entire JSON file, finds out the symbol of all right braces.
It in the present embodiment, include opening brace symbol and right braces symbol, and opening brace symbol in JSON file
It is symmetrical with right braces symbol, that is, there is an opening brace symbol just to there is a corresponding right side to include greatly in JSON file
Number symbol, for example, opening brace meet for " ", right braces meet for " ".
In the present embodiment, for the braces symbol for defining object, the object includes several key-value pairs, can be with
Including subobject；
It further include colon ": " in the JSON file, the colon symbol is used to distinguish the key and value in key-value pair, that is, emits
Before number symbol is key, and subsequent colon symbol is value；
It further include comma in the JSON file, ", wherein the comma symbol is used to indicate the knot of a key-value pair
Beam.
Specifically, according to JSON file format standard, how many is to braces symbol, with regard to how many layer data；From JSON
File the first row starts to count down line by line, and the corresponding layer of first right braces symbol is the data of innermost layer, and so on,
The corresponding layer of the last one right braces symbol is outermost data.
S62: in a layer data, the key-value pair for including is found out according to colon symbol and comma symbol symbol.
Specifically, when traversing entire JSON file, in each layer data found, a pair of keys value is distinguished with colon symbol
In key and value, i.e., be key before colon symbol, it is subsequent for value；It take comma symbol as the end mark of a pair of of key assignments.
In the present embodiment, back-end server is literary by the data that the Data Representation that Applied layer interface returns is JSON format
Part, parameter name and parameter value show as the form of key-value pair.Using recursive algorithm, successively to the data of JSON format transmission into
Row parsing, can easily obtain the sensitive information for needing to filter.
Further, in one embodiment, the data that back-end server is returned by Applied layer interface can be Map pairs
As being parsed to obtain the ginseng for including in the data in step s 2 by the data that Applied layer interface returns to back-end server
Several titles and parameter value, specific steps include:
Using recursive algorithm, the parameter name for including in Map object and parameter value are parsed.
Map object is the collection class in Java.When due to saving data with Map object, disk might not be saved to
Continuation address on, but one key and a value connected according to an index, in this way, with Map object storing data
The scattered value of the storage that can be convenient, is conducive to the fragment space using disk.Therefore, each item in a Map object set
Data are likely to be the different location that dispersion is stored in disk.
Specifically, it for the data returned with this data format of Map object, is carried out with get () method that Map class carries
Recursion resolution obtains the parameter name for including in Map object and parameter value.
Further, in one embodiment, after step S1 establishes non-sensitive information database, information filtering method is also wrapped
Include following steps:
Periodically non-sensitive information database is synchronized.
Specifically, foundation, update, the deletion of local SQLite database are bound together with program code, if quick
