When the login input identification is consistent with the login permission identification, the user is required to enter the private information display interface, and a corresponding electronic two-dimensional code is generated at the moment and is sent to the mobile equipment for the mobile equipment to enter the private information display interface.
Referring to fig. 4, the step of generating the login permission identification according to the device basic information and the scan identification time includes:
step S400: and collecting all the basic information of the equipment according to a preset information ordering sequence in the basic information of the equipment to form a basic character string.
The information ordering sequence is the ordering sequence of each information in the basic information of the equipment, for example, the basic information of the equipment comprises an equipment identity, a factory number and a production date, wherein the information ordering sequence can be the equipment identity, the reproduction date and the factory number, and the specific information ordering sequence is determined in advance by a worker; the basic character string is a character string obtained by sorting and combining all the basic information of the equipment according to the information sorting order, for example, the equipment identity is L123, the production date is x20231111, and the factory number is y.543, and the basic character string obtained according to the information sorting order corresponding to the above example is L123x20231111y.543.
Step S401: and performing character adjustment on the basic character string according to a preset character sequencing order to form an adjustment character string.
The character sequencing order is the sequencing order of the characters of all types, the character types comprise numbers, uppercase letters, lowercase letters, symbols and the like, the corresponding character sequencing order can be numbers, symbols and uppercase letters, and finally lowercase letters, and the specific order is determined in advance by staff; the adjustment string is a string obtained by adjusting the base string according to the character sorting order, and the adjustment string is 12320231111543.LYx according to the above example.
Step S402: and performing character position adjustment on the adjustment character strings according to a preset similar ordering sequence to form ordered character strings.
The similar ordering sequence is the sequence of ordering the characters of the same type, for example, for numeric characters, 0-9 is used for ordering, for alphabetical characters, the ordering is carried out according to A-Z, and the specific similar ordering sequence is determined in advance by staff; the ordered string is a string obtained by adjusting the string according to the similar sort order, and the obtained ordered string is 01111122233345. LYx, for example, as the example.
Step S403: and comparing the ordered character strings with the characters in the adjustment character strings in a one-to-one correspondence manner, and defining the characters in the ordered character strings, which do not correspond to the adjustment character strings, as misplacement characters.
The method for comparing is to compare the characters at the same position in the two character strings, for example, the first character in the ordered character string is compared with the first character in the adjustment character string, and the misplacement character is defined to identify the character inconsistent after adjustment, so that the subsequent step analysis is facilitated.
Step S404: counting according to the misplaced characters under the characters of the same type to determine the misplaced number, and arranging the misplaced number determined in each type in a character sequencing order to form a digital character string.
The number of misalignments is the number of misalignments occurring in each type of character, and is 14, 0 in this order, and the numeric string is a string obtained by combining and sorting in the order of character sorting according to the number of misalignments, and is 14000 in this example.
Step S405: it is determined whether the scan identification time is singular.
The purpose of the judgment is to further analyze the digital string.
Step S4051: if the scanning identification time is singular, generating the login permission identification according to the digital character string.
When the scanning identification time is singular, the digital character string is directly used as the login permission identification so as to encrypt the private information.
Step S4052: and if the scanning recognition time is not singular, sequencing the digital character strings from back to front to update the digital character strings, and generating the login permission identification according to the updated digital character strings.
When the scanning identification time is not singular, the digital character strings are sequenced from front to back to be used as login permission identification, so that the encryption of private information is realized.
Referring to fig. 5, after the formation of the numeric string, the step of generating the login-permitted identification further includes:
step S500: and counting characters according to the digital character strings to obtain the number of the characters.
The number of characters is the number of characters in the character string, and the number of characters is 5 by taking the above numeric character string as 14000 as an example.
Step S501: and determining a special character string set corresponding to the number of characters according to a preset special character string matching relation.
The special character string set is a set formed by character strings which can be conveniently obtained through the trial by a user, different character numbers correspond to different special character string sets, for example, when the character number is 7, the corresponding special character strings can comprise 1234567, 7654321, 1314520 and the like, the special character string matching relationship between the character number and the special character string set is specifically set by a staff according to actual conditions, and the staff inputs and stores the special character string matching relationship in advance.
Step S502: it is determined whether the numeric string is within a special string set.
The purpose of the judgment is to know whether the current numeric string is readily available during the user's attempt.
Step S5021: if the number character string is not in the special character string set, determining the login permission identification according to the number character string.
When the digital character string is not in the special character string set, the possibility that the current user enters the private information display interface through the attempted method is low, and the login permission identification is determined normally according to the digital character string.
Step S5022: if the number character string is in the special character string set, the character corresponding to the adjustment character string in the ordered character string is defined as the correct character.
When the digital character string is in the special character string set, the possibility that the current user enters the private information display interface through the attempted method is high, and the digital character string needs to be modified to reduce the possibility of the situation; correct characters are defined to facilitate distinguishing between misplaced characters.
Step S503: the correct number is determined by counting the correct characters under the same type of characters, and the correct number determined in each type is arranged in the character sequencing order to update the digital character string.
The correct number is the number of correct characters in the single type of characters, and taking the above example as an example, the corresponding correct numbers are 0, 1, 2 and 1 respectively, and the updated number character string is 0121.
Referring to fig. 6, after updating the numeric string according to the correct number, the step of generating the login-permitted identification further includes:
step S600: and judging whether the character string is in the corresponding special character string set or not according to the updated digital character string.
The purpose of the judgment is to know whether the updated character string is still a special character string.
Step S6001: if the updated digital character string is not in the corresponding special character string set, determining the login permission identification according to the digital character string.
When the updated digital character string is not in the corresponding special character string set, the digital character string is not the special character string, at the moment, the possibility that the user enters the private information display interface through an attempted method is low, and the login permission identification is normally determined according to the digital character string.
Step S6002: if the updated digital character string is in the corresponding special character string set, determining a median character in the digital character string, and performing average calculation according to all characters in the digital character string to determine a character average.
When the updated digital character string is in the corresponding special character string set, the digital character string is described as the special character string, and the possibility that the user enters the private information display interface through the trial method is still higher, so that the user needs to modify the private information display interface again; the middle character is a character in the middle of the digital character string, and when the number of characters of the digital character string is even, the character in the front of the middle two characters can be determined to be the middle character; the character mean is the average value obtained after the calculation of the sum mean of all the characters in the digital character string.
Step S601: and judging whether the character average value is larger than a preset critical value.
The threshold is a constant value set by a worker, for example, 5, and the purpose of the judgment is to perform different character string changing processes for different character average values.
Step S6011: if the character mean value is greater than the critical value, the characters before the median character are sequenced from back to front and the character after the median character is placed in order to update the digital character string.
When the character average value is larger than the critical value, sequencing the characters before the middle character from back to front and updating the digital character string after the characters after the middle character at the moment to modify the digital character string; for example, the original digital character string is 98765, the threshold is 5, and the corrected digital character string is 76589.
Step S6012: if the character mean value is not greater than the critical value, the characters after the median character are sequenced from back to front and the character before the median character is then updated.
When the character mean value is not greater than the critical value, sequencing the characters after the median character from back to front and updating the digital character string after the characters before the median character at the moment to modify the digital character string; for example, if the original number string is 12345 and the threshold is 5, the corrected number string is 12354.
Referring to fig. 7, the device management method based on the encrypted two-dimensional code further includes:
step S700: and acquiring correction input data sent by the mobile device.
The processor receives the correction input data and may analyze the data for the desired modification.
Step S701: and analyzing according to the correction input data to obtain the type of the correction data and the numerical value of the correction data.
The correction data type is the data type required to be corrected in the correction input data, such as the state of equipment, and the correction data value is the value of the data required to be corrected in the correction input data, for example, the state of the equipment is corrected from a damaged state to a normal state, and the remaining available time is switched from 5 days to 4 days.
Step S702: and determining an allowable correction range corresponding to the correction data type according to the preset type range matching relation.
The allowable correction range is a data range when the data is considered to be normal data, for example, the type of the correction data is the remaining available time length, and in general, the remaining available time length when the device is best is 100 days, the allowable correction range is 0-100, different allowable correction ranges correspond to different correction data types, and the type range matching relationship between the two is determined in advance by staff.
Step S703: and judging whether the correction data value is in the allowable correction range or not.
The purpose of the judgment is to know whether the data currently modified is normal or not.
Step S7031: if the value of the correction data is in the allowable correction range, correcting the value of the correction data on the private information display interface according to the correction input data, outputting a successful correction state and sending the successful correction state as a data correction state to the mobile equipment.
When the value of the correction data is in the allowable correction range, the data needing correction at present is normal, the corresponding data is modified on the private information display interface, and meanwhile, the successful correction state is output and sent to the mobile equipment, so that a user using the mobile equipment can know the situation.
Step S7032: if the correction data value is not within the allowable correction range, outputting a failure correction state and sending the failure correction state as a data correction state to the mobile device.
When the corrected data value is not in the allowable correction range, the condition that the data required to be corrected is abnormal at present and the data input error possibly exists is indicated, and a failure correction state is output and sent to the mobile equipment so that a user using the mobile equipment can know the condition, and the subsequent processing is facilitated.
