In this embodiment, the above scheme is applied to application management in which a visitor accesses a campus before entering the campus. Specifically, as described in step S1, the visitor may send an access request for accessing the campus at 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 face recognition when the visitor accesses the campus to pass through the access control, and the text information randomly input by the visitor is used for generating a corresponding passcode as described in step S5; the pass code is used for inputting the pass code to pass through the entrance guard when the visitor cannot use the face feature information to pass through the entrance guard, namely, the face feature information and the pass code can be used for verifying when the visitor accesses the garden area.
As described in the above steps S2-S3, based on the face feature information, detecting whether there is matched target face feature information in the database; if the target face characteristic information exists in the database, the fact that the visitor has visited the campus once is indicated, and at the moment, only the time difference between the valid period of the target face characteristic information in the database and the current time needs to be detected; the validity period of the target face feature information is usually only a few hours. Detecting whether the time difference is smaller than a preset time length or not; if the number of the visitor data is less than the preset number, the visitor is indicated to visit the park recently, so that the visitor can input data conveniently, historical visitor data of the visitor can be obtained at the moment, and desensitization treatment needs to be carried out on the historical visitor data to obtain desensitization access data in order to prevent the historical visitor data from being leaked in the transmission process; desensitizing only private data in historical visitor data in the desensitized visitor data; as described in step S4 above, the desensitized guest data is pushed to the access terminal for confirmation or modification by the guest for the guest to enter guest data; after the desensitization visitor data are pushed to the access terminal, the desensitization visitor data are automatically decrypted into visitor data; at the moment, if the visitor accesses the enterprise accessed historically, the visitor data does not need to be input manually; if the visitor accesses the enterprise which is not accessed historically, the enterprise can be modified manually; in this embodiment, the input operation of the visitor is simplified.
In an embodiment, the desensitization guest data is automatically decrypted into guest data after being pushed to the access terminal, including:
after the desensitized visitor data is pushed to the access terminal, acquiring identification information of the access terminal;
performing hash calculation on the identification information to obtain a corresponding identification hash value;
and judging whether a hash value identical to the identification hash value exists in the database or not, and if so, controlling the access terminal to automatically decrypt desensitized visitor data to obtain the visitor data.
In the embodiment, after desensitized visitor data is pushed to the access terminal, decryption processing is automatically performed, so that the visitor data is prevented from being leaked in the transmission process, and meanwhile, the operation of visitors can be reduced.
In an embodiment, after step S6 of storing the visitor data in a database in association with the facial feature information and a pass code, and sending the pass code to the visitor, the method includes:

step S9a, if the visitor is matched with the park, the visitor is released to enter the park;
s9b, if not, prompting the visitor to input a pass code; if the correct pass code input by the visitor is received, passing the visitor to allow the visitor to enter the park; if the correct pass code input by the visitor is not received, the visitor is prohibited from passing.
In the embodiment, the condition that the face recognition system of the entrance guard possibly goes down or is inaccurately recognized is considered, so that the influence on the passage of visitors is avoided; the determination of whether to permit the pass can be made based on the pass code. The pass code is generated according to the character negotiation input by the visitor, and only the visitor and the park management terminal know the pass code, so that the leakage is not worried about. In other embodiments, if the pass still fails, the corresponding Chinese character can be input, and whether the Chinese character is a Chinese character input by the visitor in advance is judged, if so, the Chinese character is released, and if not, the Chinese character is forbidden to be released.
In this embodiment, a specific scheme for generating a pass code is provided, and specifically, the step S5 of generating a corresponding pass code based on the text information includes:
step S51, acquiring characteristic information of the character information, wherein the characteristic information comprises pinyin characteristics, stroke characteristics and component characteristics of the character information; wherein, the character information is a single Chinese character; for example, chinese characters input by the visitor are: if the character is "visited", the corresponding pinyin feature is "fang", the stroke feature is "06", the component feature is "turbine", and the component is a common component in a multi-character system. People are used to refer to the upper, lower, left and right parts of Chinese characters as components. Generally, the above is called "header", e.g. "+", in the form of a Chinese character, a cursive header; the bottom is called as a dish in a basin, and the dish is called as a dish sub-bottom; the left side is called the side, such as the character radicals in the iron characters, called the side of the pyramid; the right side is called as the 'side', such as the 'bucket' in the material word, and the side is called as the 'bucket'; the outer name of the box is 'frame', such as 'Jiong' in the Chinese character 'gang', the box is called the same-word box, and some components are changed in shape at different positions, the terms are different, for example, the Chinese character 'ren' in the 'Hui' word is called herringbone head, and the Chinese character 'Xian' word is called solitary man. The above-mentioned radical characteristics express the structural characteristics of the above-mentioned Chinese characters. It can be understood that if the above-mentioned Chinese characters are polyphonic characters, the commonly used pronunciation can be taken, or any one pronunciation can be taken.
S52, generating a corresponding first character by adopting a first generation rule based on the pinyin characteristics;
step S53, based on the stroke characteristics, generating a corresponding second character by adopting a second generation rule;
step S54, generating a corresponding third character by adopting a third generation rule based on the radical characteristics; in this embodiment, the database stores the first generation rule, the second generation rule, and the third generation rule, and generates corresponding characters by using corresponding rules for the pinyin features, the stroke features, and the radical features; so that the subsequently generated pass code combines the multi-dimensional characteristics of the Chinese characters, and the marking property is enhanced. In one embodiment, the characters are numbers.
Step S55, randomly generating a non-repeated fourth character, wherein the fourth character is generated only once in a preset period; since different visitors may input the same characters, in order to distinguish the visitors, a non-repetitive fourth character is also required to be generated, and the character is generated only once in a preset period, and the fourth character is usually a number. For example, the number may be generated only once per working day, and not regenerated on the current day.
Step S56, determining a corresponding character combination rule based on the radical characteristics; wherein, the database stores the corresponding relation between the character combination rules and the radical 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 radical features, so that the difference of the radical features is conveniently embodied, and the radical features are conveniently reversely deduced according to the character combination rules.
And S57, combining the first character, the second character, the third character and the fourth character based on the determined character combination rule to obtain a combined character 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 to obtain the pass code used as the entrance guard pass verification.
In one embodiment, the pinyin features include initial characteristics, final characteristics, and tone characteristics; the step S52 of generating a corresponding first character based on the pinyin feature by using a first generation rule includes:
mapping the initial feature into a first number based on a first mapping table; in the first mapping table, each initial corresponds to a number; the number is at most two digits;
mapping the characteristics of the vowels 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 features to third numbers based on a third mapping table; in the third mapping table, each tone corresponds to a number, and the number is a digit;
sequentially connecting the first digit, the second digit and the third digit in series to obtain a serial number; judging whether the number of the numbers in the serial numbers is greater than a threshold value; if the number is larger than the first number, carrying out binary conversion on the serial numbers by adopting a 32-binary coding table, and taking the converted character as the first character; wherein, the 32-system coding table is arranged based on the initial consonant characteristics. In order to avoid overlong subsequently obtained passcodes, the length of the first character is not suitable to be overlong, and is usually not greater than four digits (the threshold value is 4), and if the number in the serial numbers is not greater than 4, the serial numbers can be directly used as the first character; if the number is more than 4, a 32-system coding table can be adopted to carry out system conversion on the serial numbers, and the character obtained by conversion is used as the first character; since the above-mentioned digits are decimal digits, the digit length can be significantly reduced after 32-ary encoding thereof. It can be understood that, after the 32-ary encoding is performed, whether the number of characters in the converted characters is greater than the threshold value may be detected again, and if so, characters with more than threshold values at the tail of the converted characters may be removed.
In this embodiment, a specific scheme for arranging a coding table is provided, where an arrangement manner of the 32-ary coding table includes:
acquiring a standard 32-system coding table; the standard 32-system coding table is a coding table preset in a campus;
the standard 32-ary encoding table is shown in table 1 below:
acquiring characters in the initial characteristics as initial characters; for example, if the initial character is "sh", the initial character is s, h;
deleting all the code symbols corresponding to the initial characters in the standard 32-system code table to obtain a plurality of vacant positions; and all the code symbols behind the gap in the standard 32-ary coding table are shifted forward to fill the gap; and filling the initial consonant characters in a vacant 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 character is s, h, the corresponding sequence is 18, 7, and after all the code symbols corresponding to the initial character in the standard 32-ary code table are deleted, the empty slots corresponding to the sequence numbers 18, 7 are obtained, at this time, all the code symbols after the sequence number 7 are translated forward, and the last two empty slots are left to be filled in the s, h, so as to obtain a rearranged 32-ary code table, as shown in table 2 below:
the rearranged 32-system coding table is different from the standard 32-system coding table, partial coding values are changed, the serial numbers are subjected to system conversion based on the rearranged 32-system coding table, the conversion result can be changed, and the 32-system coding table is unique after being rearranged and has the correlation with the consonant characters, so that the rearranged 32-system coding table can be obtained in the same way.
In an embodiment, the step of generating a corresponding first character based on the pinyin feature by using a first generation rule includes:
mapping each character in the pinyin features to a corresponding number based on a fourth mapping table; in the fourth mapping table, each character corresponds to a number.
Sequentially connecting the mapped numbers in series according to the sequence corresponding to the pinyin characteristics to obtain serial numbers; judging whether the number of the numbers in the serial numbers is greater than a threshold value; if the number is larger than the first number, carrying out binary conversion on the serial numbers by adopting a 32-binary coding table, and taking the converted character as the first character; wherein, the 32-system coding table is obtained by arranging based on the pinyin characteristics. The encoding method of the 32-ary encoding table refers to the above-mentioned embodiments, and is not described herein again.
In another embodiment, the step of generating a corresponding second character by using a second generation rule based on the stroke feature includes:
taking the number of strokes in the stroke feature as the second character; if the stroke number is 8, the second character is 08.
Based on the radical characteristics, generating a corresponding third character by adopting a third generation rule, wherein the step comprises the following steps of:
and searching the number corresponding to the radical feature as the third character based on the radical feature and the corresponding relation between the radical feature and the number stored in the database. If the database stores the correspondence between various radical characteristics and numbers, the third character can be obtained based on the radical characteristics.
In another embodiment, in order to avoid that the same pass code is produced by the chinese characters having the same pinyin feature, stroke feature and radical feature, the method further includes, after the step of determining the corresponding character combination rule based on the radical feature:
based on the phonetic features of the character information, searching a corresponding first Chinese character set in a Chinese character dictionary library; wherein, the Chinese characters in the first Chinese character set have the same pinyin characteristics;
detecting whether the number of the Chinese characters in the first Chinese character set is only one; if only one Chinese character exists in the first Chinese character set, executing the determined character combination rule to combine the first character, the second character, the third character and the fourth character to obtain a combined character as the pass code;
if the number of the Chinese characters in the first Chinese character set is more than one, searching a corresponding second Chinese character set in the first Chinese character set based on the stroke characteristics of the character information; wherein the Chinese characters in the second Chinese character set have the same stroke characteristics;
detecting whether the number of the Chinese characters in the second Chinese character set is only one; if only one Chinese character exists in the second Chinese character set, executing the determined character combination rule to combine the first character, the second character, the third character and the fourth character to obtain a combined character as the pass code;
if the number of the Chinese characters in the second Chinese character set is more than one, searching a corresponding third Chinese character set in the second Chinese character set based on the radical characteristics of the character information; the Chinese characters in the third Chinese character set have the same radical characteristics;
detecting whether the number of the Chinese characters in the third Chinese character set is only one; if only one Chinese character exists in the third Chinese character set, executing the determined character combination rule to combine the first character, the second character, the third character and the fourth character to obtain a combined character as the pass code;
if the number of the Chinese characters in the third Chinese character set is not more than one, randomly generating a non-repeated fifth character, and only generating the fifth character once in a preset period; and combining the first character, the second character, the third character, the fourth character and the fifth character based on the determined character combination rule to obtain a combined character as the pass code.
In an embodiment, the step S5 of generating the corresponding pass code based on the text information includes:
