Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is a flowchart of an entry checking method for character information according to an embodiment of the present invention. The method further comprises the following steps:
the process first proceeds to step S101 to receive input character information and input verification information. The input verification information refers to verification information generated by corresponding calculation when the input character information is correct, namely standard verification information.
Preferably, the input character information and the input verification information are generated through a security system, the security system is a non-networking system, and the input character information and the input verification information are recorded through paper media and are manually input by a user, so that the safety of information input is ensured.
Preferably, the input character information is an MD5 information code, and the MD5 information code is composed of a plurality of letters or numbers, wherein the number range is generally 0 to 9, and the letter range is a to F (equivalent to 11 to 15 in 16-system).
And then, step S102 is carried out, real-time verification information is calculated according to the input character information, whether the real-time verification information is consistent with the input verification information or not is compared, if yes, step S103 is carried out, and if not, step S104 is carried out, the verification is not carried out.
Because the real-time verification information is calculated in real time according to the input character information, when the input character information has errors, the corresponding real-time verification information is different from the input verification information, and the verification cannot be passed, thereby effectively improving the accuracy of input character information entry.
As shown in fig. 2, in some embodiments, the input character information is an MD5 information code, and the calculating the real-time verification information by the input character information includes:
the method first proceeds to step S201 to split the MD5 information code into a plurality of groups of data in units of a first number. Preferably, the first number is 8.
And then step S202 is carried out to correspondingly generate a check code according to each group of split data, so as to obtain the check code containing the grouping number of digital characters. Preferably, the generating a check code according to each split group of data correspondingly includes: and taking any one of the 1 st to 4 th bits, the average value, the maximum value, the minimum value and the median of each group of data as a corresponding check code of the group. By performing the above operations for each group, a check code having a number of digits comprising the grouping number can be obtained.
And then step S203 is entered to intercept the preset digit number of the check code containing a plurality of grouped characters to obtain real-time check information. Preferably, the first number is 8, and the preset number is 3 last bits. For example, the MD5 information codes have 32 bits in total, 8 bits are taken as a group and can be divided into 4 groups, 4 check codes are obtained by calculating 8 groups, and then the last 3 bits of the check codes are intercepted as check information.
In other embodiments, the calculating the real-time verification information from the input character information includes: dividing the MD5 information code into a plurality of groups by taking 4 bits as a group, adding each group of data (calculated by 16-system) to obtain a check intermediate value, and taking the preset number of bits of the check intermediate value as check information. For example, a 32-bit MD5 check code is "38 b8c2c1093dd0fec383a9d9ac 940515", which is divided into 4 groups, which are respectively "38 b 8", "c 2c 1", "093 d", "d 0 fe", "c 383", "a 9d 9", "ac 94" and "0515", and the 8 groups of data are added (added according to a 16-system rule), so as to obtain a check intermediate value "12 ce 3", and the last 3 bits "ce 3" of the check intermediate value is intercepted as the final check information of the MD5 check code.
In some embodiments, the input character information is an MD5 information code, and the calculating the real-time verification information by the input character information includes:
firstly, entering step S301 to split the MD5 information code into a plurality of groups of data by taking a first number as a unit;
then step S302 is carried out to execute a first operation on each group of the split data so as to generate a check code with a group number of numeric characters; the first operation comprises: multiplying each character in the split data by a numerical value of a preset gradient from left to right, then adding products corresponding to the characters to obtain an accumulated value, and taking the unit digit of the accumulated value as a check digit corresponding to the grouped split data;
then, step S302 is performed on each group of data (i.e., step S302), so as to obtain check bits corresponding to each group of split data, and the check bits corresponding to each group of split data are recombined into the real-time check information.
Also taking the MD5 check code "38 b8c2c1093dd0fec383a9d9ac 940515" as an example, it is divided into 4 groups according to 8 bits, which are: "38 b8c2c 1", "093 dd0 fe", "c 383a9d 9" and "ac 940515", for each character in the 4 groups of data, multiplying the corresponding numerical value from left to right according to a preset gradient, for example, multiplying the highest "3" in "38 b8c2c 1" by the numerical value "8", multiplying the second highest "8" by the numerical value "7", and so on, multiplying the lowest "1" by the numerical value "1", and obtaining an accumulated value. Of course, the preset gradients may be in order from small to large, such as multiplying the highest "3" by the value "1", multiplying the second highest "8" by the value "2", and so on multiplying the lowest "1" by the value "8" in "38 b8c2c 1".
And then, taking the single digit of the accumulated value corresponding to each group as the check digit corresponding to the grouped split data to obtain 4 check digits, wherein the 4 check digits form final check information. Because the check bit is corresponding to the packet split data, when the calculated real-time check information is inconsistent with the input check information, which packet data is in error can be obtained by comparing the corresponding check bit, and the user can check the table and input the data again conveniently. Preferably, when the real-time verification information is inconsistent with the input verification information, the system may prompt the corresponding split data with a prompt message, where the prompt message may be a voice prompt message or an image prompt message, for example, a highlight portion may be used to display 8-bit data with inconsistent verification bits, or which 8-bit data is erroneous may be prompted by voice. Therefore, the user can reduce the search of the error information from 32 bits (the number of bits of the whole MD5 information code) to 8 bits (the number of bits of the grouping), so that the search is facilitated, and the information calibration rate is improved.
And the inventors further provide a storage medium storing a computer program which, when executed by a processor, performs the steps of:
the character information input checking method is characterized by further comprising the following steps:
receiving input character information and input verification information;
and calculating real-time check information according to the input character information, comparing whether the real-time check information is consistent with the input check information, if so, passing the check, otherwise, failing to pass the check.

dividing the MD5 information code into a plurality of groups of data by taking a first number as a unit;
correspondingly generating a check code according to each split group of data to obtain a check code containing a first number of characters;
intercepting a preset digit of a check code containing a plurality of grouped characters to obtain real-time check information.
In some embodiments, the first number is 8, and the predetermined number of bits is the last 3 bits.
