As shown in figure 4, information collecting device 2 includes：Shell 21, writing end 22, image acquiring sensor 23 and communication unit
Member 24.
Wherein, the bottom end of shell 21 is equipped with opening 28, and the inside of shell 21 is holding part 20.
Writing end 22 is set to the bottom of shell 21, for information to be written in information input area and authentification of message region.

Case image data is sent to communication unit 24.
Communication unit 24 is set in holding part 20, is electrically connected with image acquiring sensor 23；For receiving Image Acquisition
The coding pattern image data that sensor 23 generates, and coding pattern image data is sent to external reception device.Wherein, outside
Portion's reception device can have display equipment, data processing equipment or storage device of wireless receiving function etc..
In the preferred scheme, information collecting device 2 further includes illuminating device 25, is set in holding part 20, to image
The coding pattern for the substrate that acquisition sensor 23 acquires is illuminated, so as to improve the accuracy of identification.

Further, information collecting device 2 further includes power module 27, is set in holding part 20, is passed with Image Acquisition
Sensor 23 is connected with communication unit 24, illuminating device 25 with control device 26；Power module 27 is to image acquiring sensor 23
It is powered with communication unit 24, illuminating device 25 and control device 26.
Information processing unit (not shown) is electrically connected with information collecting device 2, is received information collecting device 2 and is sent
Coding pattern image data, and coding pattern image data is decoded to obtain in substrate information input by user.
Specifically, first, multiple coding regions in coding pattern are determined according to coding pattern image data.
Wherein, in the example illustrated in fig. 3, there can be common column between adjacent encoder region, that is to say, that adjacent
Two coding regions between have overlapping region；And in yet other example, it is not overlapped between coding region.
Depending on the size of coding region can be according to preset rule, fixed part can also be set in coding pattern
It is allocated as the coding for coding region, sets rule in addition to determine the range of coding region.
Secondly, the mesh point that virtual net winding thread crosses is determined.
Wherein, each coding region includes n*n mesh point, and n is positive integer.
There are one corresponding raadable marks for each mesh point tool.It can be used for marking the coding region by raadable mark
Corresponding value information.Exactly, be marked by the position relationship between raadable mark and corresponding mesh point it is corresponding
Value information.
In preferred example, each coding region includes 4*4 raadable mark.
Then, according to each mesh point and pre-determined distance, the raadable mark in coding pattern corresponding to mesh point is determined
Center of gravity, so that it is determined that the value of raadable mark.
The schematic diagram of the coding pattern of a unit is given in Fig. 5 a- Fig. 5 d.In Fig. 5 a-5d, mesh point is labeled as
6, grid lines is labeled as 8.
The search of raadable mark can be there are two types of mode：
First, along the grid lines converged on mesh point, the weight of raadable mark is searched at the pre-determined distance apart from mesh point
The heart.
Second is that according to preset direction, the center of gravity of raadable mark is searched at the pre-determined distance apart from mesh point.It is referred to herein
Preset direction, may include that can also be defined identifiable direction including other along the direction of grid lines, such as along compiling
The diagonal in code region.
The value of raadable mark depends on relative position of the raadable mark 7 to mesh point 6.Herein only with the example of Fig. 5 a-5d
For illustrate.
Four possible positions are given in the example of Fig. 5 a-5d, from the every grid lines 8 that mesh point 6 extends
It is each that there are one raadable marks 7.
Each raadable mark 7 has preset fixed displacement relative to its mesh point 6, also, corresponds to each mesh point 6
Only there are one raadable marks 7.Certainly, if can also there is other labels in substrate, they may not be one of coding pattern
Point, for example can be the dust spot of image or figure, it is not intended to the point of figure or the label of other purposes.Due to raadable mark 7
Position must be in fixed displacement, and therefore, these other labels do not affect the identification to raadable mark 7.
For preset fixed position, for the ease of accurately identifying for raadable mark, need to follow under normal circumstances following
Rule.
In a specific example, for raadable mark 7 relative to mesh point 6 along 8 displacement 50um of grid lines, displacement is preferred
It is the 1/6 of grid interval, because in contrast this is easy to determine which mesh point some specific label belongs to.Meanwhile in order to true
Which mesh point is calibration note belong to, and the maximum value of displacement should also be limited to less than the 1/4 of grid interval.
Label expression value 1 in Fig. 5 a, the label expression value 2 in Fig. 5 b, the label expression value 3 in Fig. 5 c, in Fig. 5 d
Mark expression value 4.
Thus, each label can indicate one in four values " 1-4 ".This means that coding pattern is segmented into for X
The first position of coordinate encodes and the second position for Y coordinate encodes.
Therefore the value of label can be indicated such as the following table 1.
| Mark value | X- is encoded | Y- is encoded |
| 1 | 1 | 1 |
| 2 | 0 | 1 |
| 3 | 1 | 0 |
| 4 | 0 | 0 |
Table 1
Therefore, the value each marked is converted into the first numerical value encoded for X-, for the second value of Y- codings,
Using binary representation, by this method, two completely self-contained bitmaps are obtained by pattern.On the contrary, two or more bitmaps
It is combined into the common patterns that encoding of graphs is carried out with multiple labels according to fig. 3.
The figures that one 4*4 of different label composition of four coding patterns above may be used, to for combination
At figure, can indicate its location information with of length no more than 4 binary value sequences.
Then, the value of each raadable mark in each coding region is spliced, obtains the corresponding value letter of coding region
Breath.
In order to be better understood from technical solution, it is described in detail again by taking coding pattern shown in fig. 6 as an example.
Fig. 6 shows that the coding pattern example that there is 4*4 to mark, these labels are read by location information acquisition device.
These 4*4 are marked with following values:
4 4 4 2
3 2 3 4
4 4 2 4
1 3 2 4
These values indicate following binary system X- codings and Y- codings:
The following position in vertical bit sequence contraposition ordered series of numbers in X- codings:2046 are encoded.Between the column and the column
Difference is -2 42, their moulds 7 obtain:542, to being encoded by the location number of radix of mixed number for coding region:(5-
3) * 8+ (4-3) * 2+ (2-1)=16+2+1=19.The first coding region being encoded has location number 0.Thus, in 1 to 2 model
The difference enclosed in 4*4 labels that are interior and appearing in local surfaces is the 20th such difference.Since in addition there are three use in total
In the row of each such difference and a starting row, the vertical series of rightmost belong to the in X- codings in 4*4X- codings
61 row (row 60) (3*20+1=61), and leftmost vertical series belong to the 58th row (row 57).
The following position in horizontal position sequence number of bits row in Y- codings:0413 are encoded.Due to these levels
Bit sequence starts in the 58th row, and capable initial position is that these values subtract 57 moulds 7, obtains initial position 6302.They are converted
At using mixed number as the number of radix, become:6-2,3-2,0-0,2-2=4,1,0,0, at this, third digit is related
Least significant bit number in location number.Fourth digit is exactly the most significant digit in the next position number.
It is 0*50+4*10+1*2+0*1=42 by the location number of radix of mixed number.
Thus, the horizontal bit sequence of third in Y- codings belongs to the 43rd coding region with initial position 0 or 1, moreover,
Since for each such a total of four row of coding region, the location number of the third line is 43*4=172.
In this example, the upper left position of the local surfaces with 4*4 labels is (58,170).
Then, location information of the coding region in coding pattern is determined according to value information；Location information is combined
Generate information track and certification track.
Specifically, according to the value information got, after Data Analysis Services can obtain the coding region is encoding
Location information in pattern, then obtained all location informations are combined, to form information track and certification track, shape
At information track and certification track can the highly also information that is inputted in substrate of original subscriber.
Then, identification information track obtains user information, is searched and is reserved in user authentication data library according to user information
Authentication information.
Wherein, user information is stored in user authentication data library and user reserves authentication information；Reserved information can be used
Family signature can also be character string etc., and in specific application, user authentication data library can be the user account of bank management
Database can also be user's member database etc. of market management.
Finally, reserved authentication information is matched with certification track, obtains matching degree；When matching degree is greater than or equal in advance
If when matching degree threshold value, generating successful match prompt message；When matching degree is less than preset matching degree threshold value, generates matching and lose
Lose prompt message.
Specifically, the type that matching threshold can reserve authentication information according to user is set, different types of user
Reserved authentication information can correspond to different matching thresholds；For example, when it is character string that user, which reserves authentication information, can set
Matching threshold is 99%；When it is user's signature that user, which reserves authentication information, matching threshold can be set as 95%.
Further, authentification of message system further includes display (not shown), is connected with information processing unit, information
Matching result is sent on display and shows by processing unit.
In a preferred embodiment, authentification of message system can be also used for the typing of information, and substrate can have different classes
