Specifically, as described in the above step S1, the visitor may send an access request for accessing the campus on the access terminal, and input feature information, where the feature information includes face feature information and text information randomly input by the visitor, the face feature information is used for performing face recognition to pass through the entrance guard when the visitor accesses the campus, and the text information randomly input by the visitor is used for generating a corresponding pass code as described in the above step S5; the pass code is used for inputting the pass code to pass through the entrance guard when the visitor cannot pass through the entrance guard by using the face characteristic information, namely, the face characteristic information and the pass code can be used for verifying that the visitor accesses the garden area.
Detecting whether the matching target face feature information exists in the database based on the face feature information as described in the steps S2-S3; if the target face feature information exists, the visitor accesses the park, and only the time difference between the effective period of the target face feature information in the database and the current time is detected; the expiration date of the targeted face feature information is typically only a few hours. Detecting whether the time difference is smaller than a preset duration or not; if the historical visitor data is smaller than the preset threshold value, indicating that the visitor recently accesses the campus, and acquiring the historical visitor data of the visitor at the moment in order to facilitate the visitor to input the data, wherein the historical visitor data is required to be subjected to desensitization processing to obtain the desensitized visitor data in order to prevent the historical visitor data from being leaked in the transmission process; the method comprises the steps that only privacy data in historical visitor data are desensitized in desensitized visitor data; pushing the desensitized visitor data to the access terminal for confirmation or modification by the visitor for the visitor to input visitor data as described in the above step S4; after the desensitized visitor data are pushed to the access terminal, the desensitized visitor data are automatically decrypted into visitor data; at this time, if the visitor accesses the enterprise with history access, the visitor data does not need to be manually input; if the visitor accesses the enterprise which is not the history access, the visitor can manually modify the enterprise; in this embodiment, the input operation of the visitor is simplified.

In the embodiment, the situation that the face recognition system of the access control is possibly down or inaccurate in recognition is considered, so that the passing of visitors is prevented from being influenced; the determination of whether to pass or not may be made based on the passcode described above. The pass code is generated according to the text negotiation input by the visitor, and only the visitor and the park management end know the pass code, so that leakage is not worry. In other embodiments, if the pass is still unable to pass, a corresponding Chinese character may be input, whether the corresponding Chinese character is a Chinese character input in advance by the visitor is determined, if yes, the release is permitted, and if not, the release is prohibited.
In this embodiment, a specific scheme for generating a pass code is provided, specifically, the step S5 of generating a corresponding pass code based on the text information includes:
step S51, obtaining characteristic information of the text information, wherein the characteristic information comprises pinyin characteristics, stroke characteristics and radical characteristics of the text information; wherein, the character information is a single Chinese character; for example, the Chinese characters input by the visitor are: "visited", its corresponding phonetic feature is "fang", its stroke feature is "06", its radical feature is "" book ", and its radicals are common components in the combined word. People are familiar with the fact that the upper, lower, left and right parts of Chinese characters are commonly referred to as components. In general, the term "header" is referred to above as "" + "in the word of flowers, and the term" grass header "; the bottom is called as a dish in the basin, and the dish sub-bottom is called as a dish in the basin; the left side is called as "side", such as "side of Chinese character Ji" in Chinese character' xi; the right side is called as a 'bucket' in the material word, and is called as a bucket word side; the external terms "frame", such as "" in the oka word, refer to the same word frame, some components, and the shapes are changed at different positions, and the external terms are also different, such as "people" in the "meeting" word, refer to the header of a figure, and in the "immortal" word, refer to a single person. The character components express the structural characteristics of the Chinese characters. It can be understood that if the Chinese characters are polyphones, common pronunciation can be selected or any pronunciation can be selected.
Step S52, based on the pinyin characteristics, generating corresponding first characters by adopting a first generation rule;
step S53, based on the stroke characteristics, generating a corresponding second character by adopting a second generation rule;
step S54, based on the component characteristics, generating corresponding third characters by adopting a third generation rule; in this embodiment, the database stores the first generation rule, the second generation rule, and the third generation rule, and corresponding rules are adopted for the pinyin feature, the stroke feature, and the radical feature to generate corresponding characters; so that the subsequently generated pass codes combine the multidimensional characteristics of Chinese characters and enhance the designability. In one embodiment, the characters are numbers.
Step S55, randomly generating a fourth character which is not repeated, wherein the fourth character is only generated once in a preset period; since different guests may have entered the same text, a non-repeating fourth character, typically a number, needs to be generated for distinction, and generated only once within a predetermined period. For example, the number is generated only once every working day, and is not regenerated on that day.
Step S56, corresponding character combination rules are determined based on the component characteristics; the database stores the corresponding relation between the character combination rules and the character component characteristics; different character combination rules are adopted corresponding to different radical characteristics, and the character combination rules can be the sequence of character combination, such as third character-first character-second character-fourth character, or fourth character-third character-first character-second character. Different character combination rules are adopted corresponding to the component features, so that the difference of the component features is conveniently represented, and the component features are conveniently reversely deduced according to the character combination rules.
And step S57, based on the determined character combination rule, combining the first character, the second character, the third character and the fourth character to obtain a combined character serving as the pass code. And combining the first character, the second character, the third character and the fourth character based on the determined character combination rule, so that the pass code serving as the access control pass verification can be obtained.
In one embodiment, the pinyin characteristics include an initial characteristic, a final characteristic, and a tone characteristic; the step S52 of generating the corresponding first character by using the first generation rule based on the pinyin feature includes:
Mapping the initial consonant feature to a first number based on a first mapping table; in the first mapping table, each initial consonant corresponds to a number; the number is at most two digits;
mapping the final characteristics into second numbers based on a second mapping table; in the second mapping table, each vowel corresponds to a number; the number is at most two digits;
mapping the tone feature to a third number based on a third mapping table; in the third mapping table, each tone corresponds to a number, and the number is a one-digit number;
sequentially concatenating the first number, the second number and the third number to obtain concatenated numbers; judging whether the number of the digits in the serial number is larger than a threshold value or not; if the number is larger than the first character, a 32-system coding table is adopted to carry out system conversion on the serial numbers, and the converted characters are used as the first characters; wherein the 32-ary encoding table is arranged based on the initial consonant features. In order to avoid that the subsequent pass code is too long, the length of the first character is not too long, usually not more than four digits (the threshold value is 4), and if the number in the concatenated number is not more than 4, the concatenated number can be directly used as the first character; if the number is larger than 4, a 32-system coding table can be adopted to carry out system conversion on the serial numbers, and the converted characters are used as the first characters; since the numbers are decimal numbers, the number length can be significantly reduced after 32-ary encoding. It can be understood that after the 32-system coding is performed, whether the number of characters in the converted characters is greater than a threshold value can be detected again, and if so, characters with more tail parts than the threshold value in the converted characters can be removed.
In this embodiment, a specific scheme for arranging the encoding table is provided, where the arranging manner of the 32-ary encoding table includes:
obtaining a standard 32-ary coding table; the standard 32-system coding table is a preset coding table of a park;
the standard 32-ary encoding table is shown in table 1 below:
TABLE 1
| Sequence(s) | Coding symbol | Sequence(s) | Coding symbol | Sequence(s) | Coding symbol | Sequence(s) | Coding symbol |
| 0 | a | 8 | i | 16 | q | 24 | y |
| 1 | b | 9 | j | 17 | r | 25 | z |
| 2 | c | 10 | k | 18 | s | 26 | 1 |
| 3 | d | 11 | l | 19 | t | 27 | 2 |
| 4 | e | 12 | m | 20 | u | 28 | 3 |
| 5 | f | 13 | n | 21 | v | 29 | 4 |
| 6 | g | 14 | o | 22 | w | 30 | 5 |
| 7 | h | 15 | p | 23 | x | 31 | 6 |
Acquiring characters in the initial consonant characteristics as initial consonant characters; for example, if the initial character is "sh", the initial character is s, h;
all the code symbols corresponding to the initial consonant characters in the standard 32-system code table are deleted, so that a plurality of gaps are obtained; and shifting all the codes after the empty space in the standard 32-ary coding table forward to fill the empty space; filling the initial characters in a blank space left at the end of the standard 32-system coding table to obtain the arranged 32-system coding table.
For example, when the initial characters are s and h, the corresponding sequences are 18 and 7, after all the codes corresponding to the initial characters in the standard 32-system coding table are deleted, gaps corresponding to the sequence numbers 18 and 7 are obtained, at this time, all the codes after the sequence number 7 are translated forward, and the last two gaps are left to fill in the s and h, so as to obtain the rearranged 32-system coding table, as shown in the following table 2:
TABLE 2
| Sequence(s) | Coding symbol | Sequence(s) | Coding symbol | Sequence(s) | Coding symbol | Sequence(s) | Coding symbol |
| 0 | a | 8 | j | 16 | r | 24 | 1 |
| 1 | b | 9 | k | 17 | t | 25 | 2 |
| 2 | c | 10 | l | 18 | u | 26 | 3 |
| 3 | d | 11 | m | 19 | v | 27 | 4 |
| 4 | e | 12 | n | 20 | w | 28 | 5 |
| 5 | f | 13 | o | 21 | x | 29 | 6 |
| 6 | g | 14 | p | 22 | y | 30 | s |
| 7 | i | 15 | q | 23 | z | 31 | h |
The rearranged 32-ary code table, unlike the standard 32-ary code table, has a partial code value changed, and the serial numbers are converted based on the rearranged 32-ary code table, so that the conversion result is changed, the rearranged 32-ary code table has uniqueness and relevance with the initial characters, so that the rearranged 32-ary code table can be obtained only in the same way.
In an embodiment, the step of generating the corresponding first character using the first generation rule based on the pinyin feature includes:
mapping each character in the pinyin feature to a corresponding number based on a fourth mapping table; in the fourth mapping table, each character corresponds to a number.
The numbers obtained through mapping are sequentially connected in series according to the sequence corresponding to the pinyin characteristics, and serial numbers are obtained; judging whether the number of the digits in the serial number is larger than a threshold value or not; if the number is larger than the first character, a 32-system coding table is adopted to carry out system conversion on the serial numbers, and the converted characters are used as the first characters; wherein the 32-ary encoding table is arranged based on the pinyin characteristics. The encoding manner of the 32-ary encoding table is described in the above embodiments, and will not be described herein.
In another embodiment, the step of generating the corresponding second character using a second generation rule based on the stroke feature includes:
taking the stroke number in the stroke characteristic as the second character; if the stroke number is 8, the second character is 08.
Based on the character string feature, generating a corresponding third character by using a third generation rule, including:
and searching a number corresponding to the component feature as the third character based on the component feature and the corresponding relation between the component feature and the number stored in the database. The database stores the correspondence between various character components and numbers, and the third character can be obtained from the character components.
In another embodiment, to avoid that Chinese characters with the same pinyin characteristics, stroke characteristics and radical characteristics produce the same pass code, the situation needs to be corrected, specifically, after the step of determining the corresponding character combination rule based on the radical characteristics, the method further includes:
searching a corresponding first Chinese character set in a Chinese character dictionary base based on the pinyin characteristics of the text information; wherein, the Chinese characters in the first Chinese character set have the same pinyin characteristics;
Detecting whether only one Chinese character exists in the first Chinese character set; if only one Chinese character exists in the first Chinese character set, executing the step of combining the first character, the second character, the third character and the fourth character based on the determined character combination rule to obtain combined characters as the pass code;
