Please refer to FIG. 1 and FIG. 2, which is an encrypted password of the first embodiment obtained by the method of cipher encoding of the present invention. First, as shown in FIG. 1, the method for cipher encoding of the present invention includes providing a password (step S100), wherein the password includes a plurality of preset symbols, as shown in FIG. 2, the bottom line number 1, 2, 3 and 4, the plurality of preset symbols may be the same or different from each other, and may be, for example, selected from the group consisting of a numeric character and an English character, but the invention is not limited thereto, and may be, for example, according to actual needs. Adjust the number of characters in the preset symbol.

Next, step 110 is performed to arrange at least one start symbol, such as the bold and italic English alphabet A in FIG. 2 adjacent to each preset symbol to form a plurality of combined symbols 10, 11, 12 and 13 respectively. S120), wherein the start symbol may be selected from the group consisting of a digital character and an English character, for example, but the invention is not limited thereto, and the number of characters of the start symbol may be adjusted according to actual needs, for example.

In other words, the start symbol can be, for example, contiguously before and/or after each preset symbol, and can be randomly set or arranged, for example, by the online banking system software, or can be used by the user. The requirement selectively transforms the starting symbol. By starting the symbol, for example, contiguously before the preset symbol, the system software or the user can clearly know that the digital character or the English character that is adjacent to the start symbol is formed by the preset symbol when decrypting. Password.

In addition, the system software referred to in the present invention is only used to achieve the method of cryptographic coding of the present invention, and therefore, those having ordinary knowledge in the technical field of the present invention should know the system soft system without any difference according to the disclosure of the present invention.

Finally, step S130 is performed to arrange a plurality of strings 20, 21, 22 and 23 adjacent to each of the combined symbols 10, 11, 12 and 13, which strings 20, 21, 22 and 23 can be sorted, for example, by adjacency adjacent to the combined symbol 10 And before, and/or after 11, 11, 12 and 13, the encryption password is formed by the action of encrypting the password (step S140), wherein the plurality of strings 20, The 21, 22, and 23 systems are each composed of a plurality of random symbols, and the plurality of random symbols can be, for example, selected from the group consisting of a numeric character and an English character.

In other words, the plurality of random symbols may be identical or different from each other as the random symbols 8, 6, and 9 in the string 20 are different from each other. The number of characters of the plurality of strings 20, 21, 22, and 23 composed of a plurality of random symbols may be the same or different from each other, for example, the number of characters of the strings 20, 21, 22, and 23 is 3, and The encrypted cipher may be formed, for example, by sorting adjacently before the contiguous ordering of the respective combined symbols 10, 11, 12, and 13.

In addition, since the contiguous numeric character or English character after the starting symbol is the password formed by the preset symbol, the starting symbol needs to be different from the plurality of random symbols to avoid, for example, an ATM or an online banking. The system software misjudges when decrypting.

When decrypting, if the system software or the user sets the starting symbol to be set to adjacency before the preset symbols, the plurality of preset symbol systems can be sorted according to the starting symbol set by the system software or the user. After this start symbol. Therefore, each of the preset symbols located after the start symbol is captured during decryption, and the preset symbols captured by the user may be sorted by left-to-right adjacency, and the password preset by the user may be obtained. The present invention is not limited thereto, and the preset symbols captured by the right-to-left neighboring order may be sorted, for example, according to actual needs.

Therefore, when decrypting the encrypted password shown in FIG. 2, first, each of the preset symbols 1, 2, 3, and 4 located after A is extracted according to the set start symbol A.

Please refer to FIG. 3, which is an encrypted password of the second embodiment obtained by the method for cryptographic coding of the present invention. The start symbol can be composed, for example, of two numeric characters or English characters, such as A5 in bold and italic in FIG. 3, and can be, for example, contiguously sorted after each preset symbol, such as In Fig. 3, the numbers 1, 2, 3 and 4 of the bottom line are added to form a plurality of combination symbols 30, 31, 32 and 33, respectively.

In addition, the plurality of strings 40, 41, 42 and 43 are each composed of a plurality of random symbols, and the strings 40, 41, 42 and 43 can be sorted, for example, individually adjacent to the combined symbols 30, 31, 32 and 33. . The number of characters of the plurality of strings 40, 41, 42 and 43 may be, for example, different from each other. If the number of characters in the string 40 is 4 and the number of characters in the string 41 is 3, the number of characters in the string 40 and the string 41 is different from each other.

In other words, the plurality of random symbols may be the same or different from each other, for example, the random symbols 9, 8 and 1 of the string 41 are different from each other, and the random symbols 8, 8 and 8 of the string 43 are identical to each other. . And the starting symbol needs to be different from the plurality of random symbols. For example, the random symbols in the strings 40, 41, 42 and 43 are different from A5 consisting of digital characters and English characters.

When decrypting, if the system software or the user-set starting symbol is set to be adjacent to each preset symbol, the plurality of preset symbol systems can be sorted according to the starting symbol set by the system software or the user. Before this start symbol. Therefore, each of the preset symbols located before the start symbol is retrieved at the time of decryption, and for example, the preset can be retrieved. The symbols are sorted by the left-to-right order, and the passwords preset by the user are obtained, but the invention is not limited thereto, and the preset symbols captured by the right-to-left sequential sorting according to actual needs may be used, for example. .

Therefore, when decrypting the encrypted password shown in FIG. 3, the preset symbols 1, 2, 3, and 4 located before A5 are first retrieved according to the set start symbol A5. Then, for example, the preset symbols 1, 2, 3, and 4 that are captured can be sorted by left-to-right adjacency, and the password preset by the user is 1234.

Please refer to FIG. 4, which is an encrypted password of the third embodiment obtained by the method for cipher coding of the present invention. The start symbol may be composed of, for example, two numeric characters or English characters, respectively, as shown in FIG. 4 with bold and italic 5 and 7 and may be, for example, contiguously arranged before each preset symbol. The symbols are added as shown in Fig. 4 to the numbers 1, 2, 3 and 4 of the bottom line, whereby a plurality of combination symbols 50, 51, 52 and 53 are formed, respectively.

In addition, the plurality of strings 60, 61, 62, 63, and 64 are each composed of a plurality of random symbols, and the strings 60, 61, 62, 63, and 64 can be ranked adjacent to each of the combined symbols 50, 51, 52, for example. Before and/or after 53 and 33, the strings 63 and 64 are respectively adjacent to each other before and after the combination of symbols 53.

Moreover, the start symbol needs to be different from the plurality of random symbols. For example, the random symbols in the strings 60, 61, 62, 63, and 64 are different from the start symbols 5 and 7, but the present invention is not limited thereto, that is, if An encrypted password that conforms to the above encoding rules is within the scope of the claimed invention.

When decrypting, if the system software or the user sets the starting symbol system If the adjacency is sorted before each preset symbol, the start symbol of the system software or the user may be used to know that the plurality of preset symbol constellations are sorted after the start symbol. Therefore, each of the preset symbols located after the start symbol is captured during decryption, and the preset passwords can be sorted by left-to-right adjacency, for example, to obtain a password preset by the user.

Therefore, when decrypting the encrypted password shown in FIG. 4, the preset symbols 1, 2, 3, and 4 located after 5 and 7 are first retrieved according to the set start symbols 5 and 7. Then, for example, the preset symbols 1, 2, 3, and 4 that are captured can be sorted by left-to-right adjacency, and the password preset by the user is 1234.
