Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
First state, Base64 standard involved in the present invention and QR code standard are open standard, and those skilled in the art can obtain correlation technique data, does not repeat them here.
As shown in Figure 1, in the method for making of the two-dimension code pattern of the first embodiment, the information for two-dimension code pattern to be encoded comprises the Equations of The Second Kind information of disclosed type I information and secret, and this method for making comprises the steps:
S1: encode to type I information, generates the first data group;
S2: encode to Equations of The Second Kind information, encrypt, generates the second data group;
S3: described first data group, self-defining separator are linked in sequence into the 3rd data group with the second data group;
S4: generate two-dimension code pattern by described 3rd data group.
Wherein, the coding step in described step S1 adopts QR code standard.Coding step in step S2 also adopts QR code standard, and encrypting step adopts Base64 standard.In described step S4, generate two-dimension code pattern according to QR code standard by the 3rd data group.Coding step in step S1, step S2 can also adopt other Quick Response Code standards, and this will determine according to the two-dimension code pattern type of selected use, as long as the Quick Response Code Code And Decode standard be suitable for, all can directly adopt.The step that 3rd data group generates two-dimension code pattern is also like this, can adopt all known two-dimension code pattern technology comprising QR code standard.
As preferably, described self-defining separator adopts the full stop in QR code standard.Like this, for the general Quick Response Code decode system adopting QR code standard, the data after separator are no longer decoded.In a word, the effect that " self-defining separator " must play segmentation first group of data and second group of data is somebody's turn to do.If adopt the full stop in QR code standard, when adopting the decoding software of general QR code standard to decode, when running into full stop, will think that the 3rd data group terminates, only processing the first data group before being positioned at full stop.
The present embodiment by adopt separator, achieve a two-dimension code pattern and can carry two classes or the above information of two classes, realize one yard dual-purpose even multiplex, by adopt cryptographic means, realize the safe transmission of private information.Wherein, type I information can be the public informations such as network address, general text, picture, Equations of The Second Kind information be account, password, personally identifiable information etc. comparatively responsive be not easy to disclosed private information.Adopt the solution of the present invention, a two-dimension code pattern can carry two category informations, private information can not identify by general decoding device (software), be conducive to the safe transmission of information, but this two-dimension code pattern can carry disclosed information again simultaneously, can do propaganda and promote the use of, make full use of the feature contained much information that two-dimension code pattern has, reduce the quantity of the two-dimension code pattern used.
As shown in Figure 2, the coding/decoding method of the two-dimension code pattern of the second embodiment comprises the steps:
S1: scanning two-dimension code pattern, obtains the 3rd data group,
S2: detect in described 3rd data group whether comprise self-defining separator, if comprised, performs step S31, otherwise performs step S32: display error information.
S31: the data extracted in the 3rd data group after being positioned at separator are the second data group, are then decrypted the Equations of The Second Kind information obtaining secret with decoding step.
As preferably, described self-defining separator adopts the full stop in QR code standard.
Corresponding with the method for making of above-mentioned two-dimension code pattern, the decryption step in step S31 adopts Base64 standard, decoding step to adopt QR code standard.Certainly, the decoding step in step S31 is determined according to this two-dimension code pattern institute's accepted standard, and the encryption method that decryption step adopts according to Equations of The Second Kind information is determined.
The embody rule situation of above-mentioned first embodiment and the second embodiment is illustrated below in conjunction with Fig. 3 and table 1.
Wherein, by the type I information listed by table 1 and Equations of The Second Kind information according to the process encoding shown in Fig. 1, and encrypting step adopts Base64 standard, and coding adopts QR code standard, obtains the first data group as shown in table 1 and the second data group, use branch "; " as separator, be merged into the 3rd data group:
" http://www.yopoint.net/merchant.action code=WVBDVE0lM0JNOTk5OTk5OTk5OTk5OSUzQnRlcS3RzaG9w; TTk5OTk5OTk5OTk5OTt0ZXN0c2hvcA==", employing QR code standard is generated two-dimension code pattern as shown in Figure 3.When decoding to the two-dimension code pattern shown in Fig. 3, just obtain the Equations of The Second Kind information in table 1.If adopt the Quick Response Code decode system of prior art as shown in Figure 4 to decode to the two-dimension code pattern shown in Fig. 3, obtain the type I information in table 1.
Table 1 type I information and Equations of The Second Kind information is corresponding with the data after its coding shows
Fig. 5 shows the process flow diagram of the coding/decoding method of the two-dimension code pattern of the third embodiment of the present invention.As shown in Figure 5, the difference of the 3rd embodiment and the second embodiment is, while extraction second data group, extracts the first data group, and carries out decoding to the first data group and obtain type I information.Same as the prior art to the decode procedure of the first data group, repeat no more.
Above embodiment is only exemplary embodiment of the present invention, and be not used in restriction the present invention, protection scope of the present invention is defined by the claims.Those skilled in the art can in essence of the present invention and protection domain, and make various amendment or equivalent replacement to the present invention, this amendment or equivalent replacement also should be considered as dropping in protection scope of the present invention.
