Referring to fig. 3, based on the above apparatus for controlling printing of a password envelope, the present invention further provides a method for controlling printing of a password envelope.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for controlling printing of a password envelope according to an embodiment of the present invention.
The printing control method of the password envelope comprises the following steps:
s10, acquiring a preset password and a preset interference code;
s20, obtaining printing arrangement codes according to the relation between the preset passwords and the preset interference codes;
the preset code and the preset interference code jointly form printing arrangement codes, so that the continuity of the code is interrupted, the reading difficulty in fuzzy identification is interfered, and only the preset interference code does not influence normal reading.
And S30, printing the printing area according to the printing arrangement code.
In the technical scheme provided by the invention, a printing area 1 is formed on the inner side wall of the password envelope 100, when the password envelope 100 is printed, the preset password and the preset interference code are firstly obtained, the preset password and the preset interference code are arranged in a disorderly manner to form a printing arrangement code, and the printing arrangement code is printed in the printing area, so that when a person observes in a state of not opening the envelope, the person is interfered by the preset interference code, wrong information is obtained, an accurate password cannot be obtained, the safety of the information is ensured, and the leakage is prevented.
Further, in this embodiment, the preset interference code includes a plurality of first interference characters;
step S20 includes:
s21, acquiring a preset printing offset;
and S22, respectively arranging the first interference characters to the head and the tail of a preset password according to the printing offset to obtain a printing arrangement code.
In this embodiment, by printing the offset, the preset password is offset backwards by a certain number of characters, and no interfering character is arranged in front of the preset password, and the interfering character is arranged at the head and the tail of the preset password, so that the user cannot directly obtain the position of the head character or the position of the end character of the preset password, and the reading difficulty is increased.
It should be noted that, in this embodiment, if the printing offset is set to 0, the preset password is directly printed, and after the preset password is printed, a plurality of first interference characters are subsequently printed; if the printing offset is set to be 1, printing one bit to print a first interference character, then printing a preset password, and after the preset password is printed, continuously printing the remaining first interference characters, and so on.
Furthermore, the preset password comprises a plurality of password characters, and the preset interference code comprises a plurality of second interference characters;
step S22 further includes:
s221, the plurality of password characters and the plurality of second interference characters are arranged in a staggered mode, and printing arrangement codes are obtained.
In order to further prevent information leakage, a plurality of second interference characters are arranged among the password characters, so that the whole preset password is not continuous, the leakage of the information is prevented to the maximum extent, and the problem that a subsequent password can be directly obtained after the first position of the preset password is observed is further avoided.
Furthermore, the step of interleaving the plurality of password characters and the plurality of second interference characters further comprises:
acquiring the number of preset characters;
dividing a plurality of password characters into a plurality of password groups according to the number of preset characters;
the plurality of cipher blocks are interleaved with the plurality of second interference symbols.
In order to ensure the continuity of the password in reading, a certain number of password characters form a password group together, and the plurality of password groups and the plurality of second interference characters are arranged in a staggered manner, so that when the password envelope is observed, information cannot be accurately acquired due to the interference of the second interference characters, and meanwhile, when the password envelope is normally disassembled for reading, the reading difficulty is reduced, and the character splicing reading is not needed.
It should be noted that, in this embodiment, the minimum number of the preset characters is 4, and the maximum number is not more than 8; in this embodiment, if the number of the preset characters is 4, every four password characters form a password group, and a second interference character is inserted between the multiple password groups; and so on.
In addition, after the step of obtaining the number of the preset characters, the method further comprises obtaining the number of the preset interference, and obtaining the inserted second interference characters through the number of the preset interference so as to insert the second interference characters into the password group.
It should be noted that there are various embodiments of the preset password, the first interference character and the second interference character, and in the present invention, the type of the preset password is different from that of the first interference character, and likewise, the type of the preset password is different from that of the second interference character; so as to facilitate normal reading of the password and prevent the password from being abnormal due to the fact that the password is a number or a letter.
In this embodiment, the first interference character includes an interference letter. In the use environment of the invention, the password is mostly a number, so in order to avoid interfering with normal reading, the first interfering character is set as a letter, so that the user can distinguish conveniently. Note that, in this embodiment, the letters are in lower case, so that when viewed outside the envelope, a part of the letters cannot be accurately distinguished from the numbers.
Likewise, the second interference character includes an interference letter. So as to facilitate the normal use of the cipher envelope,
it should be noted that, in the setting of the two related technical features, the first interference character and the second interference character, may exist alternatively or simultaneously, and in this embodiment, the first interference character and the second interference character exist simultaneously, so as to facilitate printing, and there is no need to change the character library many times.
On the other hand, a confidential shading area is arranged on the outer side wall of the password envelope 100 corresponding to the printing area;
step S30 is followed by:
and S40, printing the secret shading area according to the preset secret shading.
The difficulty of observing the internal content from the outside of the password envelope 100 is further increased, and after the password and the interference code are printed, the preset secret shading is printed in the secret shading area, so that the sight of observation is disturbed.
It should be noted that the security shading has a plurality of arrangements, such as printing characters, patterns or a combination of the two; similarly, the security shading may be printed in color for aesthetic reasons, such as printing a colored layer to provide aesthetic benefits while preventing access to the content from outside the envelope 100.
Further, the inside wall of the envelope 100 facing the print area 1 is also provided with a carbonless copy paper, and in this embodiment, the printing method is needle printing. So that the password envelope 100 can be printed without being opened, the leakage environment can be avoided to the maximum extent, and the content in the password envelope 100 can be further protected.
