Wherein, multistage character library includes the character library of at least two ranks, and the attribute of the Chinese character in the character library of different rank
Difference, attribute includes the number and conventional property of the Chinese character of the character library.
Investigated according to commonly used word, it is proposed that level Four character library.The investigation situation of commonly used word is as follows：
(1) State Language Work Committee, State Education Commission issue for 1988《Modern Chinese commonly used word
Table》, wherein Chinese characters in common use are divided into commonly used word (2500 word) and time two parts of commonly used word (1000 word).Wherein, through computer
Sampling Detection, commonly used word coverage rate in Chinese material reaches 99.48%.
(2) GB2312 is chinese national standard simplified Chinese character collection, full name《Chinese Character Set Code for Informati-
Baseset》.At present, the almost all of Chinese information processing system in China's Mainland and internationalized software all support GB2312.GB2312 standards are supplied
6763 Chinese characters, wherein first-level Chinese characters 3755, the Chinese characters of level 2 3008 are included.
(3) also with extremely low some words of probability of occurrence, referred to as rarely used word, beyond the Chinese character of GB2312 scopes, substantially may be used
To be added using GB13000 character set.
The level Four character library includes four ranks, respectively zero level, the first order, the second level and the third level, wherein, zero level
Chinese character in character library is conventional surname word, i.e., common 206 Chinese surnames are designed as into zero level character library, among these including various schools of thinkers
Preceding 189 Chinese characters in surname, in addition plus the first character in the 17 common two-character surnames selected.
Chinese character in first order character library is conventional name word, i.e.,《Modern Chinese commonly used word table》In commonly used word selection
2311, it is used as common name word.《Modern Chinese commonly used word table》In commonly used word be 2500, herein face by those
The Chinese character occurred in zero level character library is rejected, and is substantially unsuitable as the Chinese character of name.
Chinese character in the character library of the second level is extension name word, i.e., 4246 are selected from GB2312 character set, expansion is used as
Open up name word.6763, GB2312 standard firsts and seconds Chinese characters palace, occurs in zero level, the first order is removed, remaining
4246.
Chinese character in third level character library is to refer to name word, it is contemplated that rarely used word and more be named in name can
Can, the Chinese character in GB1300 character sets is removed to the Chinese character occurred in above-mentioned three-level, remaining all Chinese characters are used as reference
Name word.
To sum up, this level Four character library structure, Chinese character is classified substantially according to name with the frequency of use of word,
More Chinese character in " surname " and " name " largely will appear in zero level and first order character library, then using second level word
Storehouse represents more Chinese characters in common use, and third level character library is then in order to which ensure during rarely used word being capable of smooth desensitization process.
In the step s 120, for any Chinese character in the name to be desensitized, scaling method is become according to default individual character, it is determined that
The Chinese character of any Chinese character in the character library of affiliated rank after corresponding desensitization, comprises the following steps, its flow chart is shown in Fig. 2.
S200, scaling method is become according to default individual character, it is determined that in the character library of any affiliated rank of Chinese character, after desensitization
Position offset of the Chinese character with respect to any Chinese character.
S210, according to the position of any Chinese character in affiliated character library, and the above-mentioned position offset determined, it is determined that de-
Chinese character after quick.
The individual character wherein prestored becomes scaling method, is that the Chinese character after desensitization is determined according to preset formula.Offset meaning in this
Think of is mobile number of words of the Chinese character relative to another Chinese character in multistage character library.
In step S210, according to the position of any Chinese character in the character library of affiliated rank, and the upper rheme determined
Offset is put, it is determined that the Chinese character after desensitization, including：
Chinese character after desensitization is determined according to formula (1), formula (1) is as follows：
NResPos=(nPos+nBias+K) mod nLevelLength (1)
Wherein, position-orders of the nResPos for the Chinese character after the corresponding desensitization of any Chinese character in the character library of affiliated rank
Number, nPos is the position number of any Chinese character in affiliated character library, and nBias is the Chinese character after the desensitization with respect to any Chinese
The position offset of word, K is the nonnegative integer set, and nLevellength is the Chinese of the character library of any affiliated rank of Chinese character
Word number；Mod is modulo operation.
Wherein offset nBias calculating is according to below equation (2)：
NBias=nLevelLength × nNameLen/M (2)
Wherein, nNameLen is the number of words of name to be desensitized, and M is the positive integer set, nBias round numbers.
According to the attribute of level Four database, first in any Chinese character in name to be desensitized is not the name to be desensitized
During individual Chinese character, i.e. the Chinese character is not this when " surname " in the name that desensitizes, or when name desensitize is two-character surname, any Chinese character
For the two-character surname second word when, then in step s 110, i.e., from the multistage character library prestored, search the level belonging to the Chinese character
Before other character library, also include：
By the Chinese character in the character library of the first two rank of the multistage character library according to the Chinese character in first rank character library preceding,
The order of Chinese character in second rank character library sum again is merged, and is used as the character library of new rank；Wherein, each Chinese character is merging
Position in character library afterwards relative to other Chinese characters in affiliated simple malapropism storehouse is constant.
Such as, it is not the first of the name to be desensitized when any Chinese character in name to be desensitized in above-mentioned level Four character library
During individual Chinese character, then by the zero level and first order character library in the level Four character library according to zero level character library preceding, first order character library exists
After merge, a new character library is constituted, relative to affiliated in the character library of each Chinese character in the new character library after merging
Former zero level, other Chinese characters in first order character library position it is constant.
Treat desensitization name carry out the desensitization of each Chinese character after, according to each Chinese character in name to be desensitized one by one
Corresponding order, by the Chinese character composition desensitization name after desensitization.
In desensitization, there is a certain character to be desensitized in some exceptions, such as a certain name to be desensitized not to be
Chinese character, or the multistage character library that Chinese character but be not belonging to prestores, then do not do any processing, directly in desensitization to the character
Output, is used as the desensitization character of the character to be desensitized.
After desensitization name is obtained, the name that the name that desensitize can also be reduced into before desensitization, its method flow diagram is shown in
Shown in Fig. 3, comprise the following steps that shown：
S300, obtains the name that desensitized.
S310, for each desensitization Chinese character in the name that desensitized, from the multistage character library prestored, searches this and has taken off
Character library belonging to quick Chinese character.
S320, according to default individual character retrieving algorithm, determines that the Chinese character that desensitized is corresponding in the character library of affiliated rank
Chinese character before desensitization.
S330, based on the Chinese character before each corresponding desensitization of desensitization Chinese character in the name that desensitized, before generation desensitization
Name.
Wherein, in step s 320, for any desensitization Chinese character in the name that desensitized, reduce and calculate according to default individual character
Method, determines any Chinese character of the Chinese character in the character library of affiliated rank before corresponding desensitization that desensitized, comprises the following steps, it flows
Journey figure is shown in Fig. 4.
S400, according to default individual character retrieving algorithm, it is determined that in the character library of any affiliated rank of the Chinese character that desensitized, institute
State position offset of the Chinese character with respect to any Chinese character that desensitized before desensitization.
S410, according to any position of the Chinese character in the character library of affiliated rank of having desensitized, and the position determined
Offset, it is determined that the Chinese character before desensitization.
In step S410, the Chinese character before desensitization is determined according to below equation (3)：
NResPos=(nPos+nLevelLength-nBias-K) mod nLevelLength (3)
Wherein, nResPos is the Chinese character before the corresponding desensitization of any Chinese character that desensitized in the character library of affiliated rank
Position number, nPos is any position number of the Chinese character in affiliated character library that desensitized, and nBias is relative for the Chinese character before desensitization
The position offset of any Chinese character that desensitized, K is the nonnegative integer set, and nLevellength is any Chinese character institute that desensitized
Belong to the Chinese character number of the character library of rank；Mod is modulo operation；
Position offset of the Chinese character before the desensitization with respect to any Chinese character that desensitized is determined according to below equation (4)：
NBias=nLevelLength × nNameLen/M (4)
Wherein, nNameLen is the number of words for the name that desensitized, and M is the positive integer set.
In individual character retrieving algorithm, to make it that the name that desensitized is reduced to the name before correspondence desensitizes completely,
Formula (3) and K values and M values in formula (4) should ensure that equal with the K values and M values in formula (1) and formula (2) respectively.In tool
In body embodiment, typically in a desensitization and corresponding reduction process, K values are as M value values.K values can be by
Client oneself grasps.
Equally, according to the attribute of level Four database, when any Chinese character that desensitized in the name that desensitized is not that this has desensitized
During first Chinese character in name, i.e., when the Chinese character that desensitized is not " surname " in the name that desensitized, or the surname that ought desensitize
Entitled two-character surname, this is any desensitized second word that Chinese character is the two-character surname when, then in step S310, i.e., from the multistage prestored
In character library, before the character library for searching the rank desensitized belonging to Chinese character, also include：
By the Chinese character that desensitized in this character library of the first two rank of multistage character library according in first rank character library
Chinese character is preceding, and the order of Chinese character in second rank character library sum again is merged, and is used as the character library of new rank；Wherein, each
Position in the character library of Chinese character after merging relative to other Chinese characters in affiliated simple malapropism storehouse is constant.
Such as, it is not the desensitization name when any Chinese character that desensitized in the name that desensitized in above-mentioned level Four character library
First desensitized Chinese character when, then by the zero level and first order character library in the level Four character library according to zero level character library preceding,
One-level character library is merged after, is constituted in the character library of each Chinese character after merging in a new character library, the new character library
Position relative to other Chinese characters in affiliated former zero level, first order character library is constant.
After the reduction of each Chinese character that desensitized is carried out to the name that desensitized, according to in the name that desensitized it is each
Desensitize the one-to-one order of Chinese character, by the name before the Chinese character composition desensitization before the desensitization of acquisition.
In reduction process, it is not Chinese character to have a certain desensitization character in some exceptions, such as a certain desensitization name,
The multistage character library that either Chinese character but be not belonging to prestores, then do not do any processing in desensitization to the character, directly output,
It is used as the desensitization character of the character that desensitized.
For the ease of being better understood from the desensitization method of Chinese Name, the part in above-mentioned level Four character library is intercepted, is based on
This, is described in detail with a specific embodiment below：
