The N system code is converted to M system code by (1c)；
(2) M system code is converted into UNICODE or ASCII to encode；
(3) UNICODE or ASCII code conversions are source information and to output it by terminal device, due to terminal device with
Server system establishes communication, therefore after M system code to be converted to UNICODE or ASCII codings, the terminal device is just
Source information can be converted into according to the information that server system stores.
For convenience of understanding technical scheme, the implementation process of the present embodiment is explained with several examples below
State.
By taking binary system and ternary conversion as an example, even N=3, M=2, and the M system code in the present embodiment is 8
Bit code form.First, black, red, blue three-color is picked out from RGB color table, then formulates one according to the color selected
Code database, due to N=3, therefore the code database is ternary code database, by the radix in the color selected and ternary code database
Matched, even：Black=0, red=1, blue=2.
Assuming that four characters of selection are needed to be used to colour composition color character security code in the packaging of product, then according to
Selected color and numerical value definition and standard code provide that can represents ten's digit 0-80 after this four rendering characters,
81 numbers altogether.Further, if the source information content of input is ten's digit 29, mistake mentioned above, in the present embodiment
M system code be 8 bit code forms, therefore the data being converted into after M system code (i.e. binary coding) are just
00011101, N systems number (i.e. trit) is then reconverted into, due to have selected four characters, therefore the trit is 4
Position ternary form, the data after changing are just into 1002, and according to matched rule, color sequences corresponding to four characters are just distinguished
For red, black, black, blueness, the color character being output to finally by output equipment on product is by this four characters
Corresponding color alignment combination is formed, i.e., the color disposal order of the color character is red, black, black, blueness.
Similarly, if the source information content of input be ten's digit 57, be converted to after binary number as 00111001, then
Be converted into after trit being 2010, then accordingly, color sequences corresponding to four characters be respectively just blueness, black, red,
Black, the color character being finally output on product are to be combined to form by the color alignment corresponding to this four characters, i.e., should
The color disposal order of color character is blueness, black, red, black.
The decoding process of above-mentioned two example is completely the same, and terminal device is according to the color selected and ternary code database
Color in color character is put in order replace with trit one by one by matched rule according to it, such as color character color row
The order of row is red, black, black, blueness, then replace with as 1002 after trit, then by this change after three
System number is converted to binary number 00011101, UNICODE or ASCII codings is then converted thereof into again, finally according to service
UNICODE the or ASCII code conversions can be obtained source information content 29 by the information of device system, other the like.
Embodiment 2
As shown in Figure 3,4, the difference from embodiment 1 is, coding and output of the embodiment 1 for non-encrypted source information,
The present embodiment is then before source information is converted into M system code, and also being superimposed One-way encryption algorithm thereon, (such as MD5 is mono-
To AES or secondary MD5 One-way encryption algorithm), and decoding when, by M system code be converted to UNICODE or
After ASCII codings, also it is decrypted using unidirectional decipherment algorithm, then reconvert obtains source information, whole source information

By taking binary system and ternary conversion as an example, even M=2, N=3, black, red, blue three-color, Ran Houjian are selected
Vertical ternary code database, and make：Black=0, red=1, blue=2.
Assuming that the source information for needing to encode is hexadecimal string 20130522, and prescribed product packs a upper word
Include four colors in symbol, after the source information is inputted, according to the rule of secondary MD5 One-way encryption algorithm first by its turn
Change secondary ciphertext 408B6B4A376A688A into, while a corresponding source document-ciphertext contrast relationship is established in server system
Table, so that the later stage can decrypt to obtain source information.After character string is converted to secondary ciphertext, then the secondary ciphertext is converted to two and entered
Number processed：001101000011000000111000010000100011011001000010001101000100000100110011
00110111001101100100000100110110001110000011100001000001, then again by the binary data
Trit is converted to, the trit after conversion is：1221121020022110200021101221210212202001200
021022000200220022102, due to including four colors, therefore the colour finally exported on product in a character
Character is made up of 16 endianness orders, and the combination of its color puts in order as red blue red, red blue red-black, blue-black
It is black it is blue, it is blue it is red it is black, blue-black is black, it is blue it is red it is black, it is red it is blue it is red, blue red and black is blue, it is red it is blue it is black, blue-black is dark red, blue-black is black,
