Fig. 3 is the file identification method flow chart based on two dimensional code that the embodiment of the present invention one provides.
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to the scope of the present invention.
It can not achieve in view of existing method and meet the needs of different application scene, quickly and easily data medium acquisition
Method, the embodiment of the invention provides a kind of acquisition methods of two-dimensional code data carrier.
Embodiment one
The present embodiment provides a kind of acquisition methods of two-dimensional code data carrier, as shown in figure 3, design cycle of the invention is such as
Under:
1. file content typing
File type can be with are as follows: official document, legal documents, examining report, all kinds of bulletins, all kinds of notices etc.
The typing of file content, which can be, is responsible for information collection by authoritative unit.Certain this kind of mode, mainly for law
The file content that letter is issued by special unit.
2. generating two dimensional code
Above-mentioned two dimensional code is a kind of two dimensional code of high capacity.Two dimensional code can support the total amount of the file information, i.e. file
Information can all be encoded as binary data, and store into two dimensional code.It can also be stored in its outer two dimensional code related on file
Information, for example there was only file main contents information on file, but the telephone number etc. of the unit can be stored in two dimensional code
Other sensitive and crucial information.The generating process of two dimensional code is a kind of generation program of stand-alone development, is a kind of private
Generation method.Generating process combines a variety of encryptions and compress technique, and tactical rule complicated difficult is to crack.Above-mentioned a variety of encryption skills
Art can be asymmetric encryption, symmetric cryptography etc..Above-mentioned compress technique is mainly binary compression algorithms.So two dimensional code is
It can not forge, can not distort, it is ensured that the safety of data.Since all data have been stored in two dimensional code, so
Server is not needed to support data to store, cost is greatly saved.The information in original data library will be by two one by one
Dimension code is undertaken, and the decentralization of data is realized.
Two dimensional code is presented in conjunction with file
Two dimensional code can bind directly electronic document, and directly two dimensional code is encoded on electronic document.One can also be set up another
Page pdf stores two dimensional code, and new pdf document is generated together with electronic document.
The display form of two dimensional code can also print together with file, and General Two-Dimensional code can be presented on the tail portion of file.It beats
When printed text part, directly two dimensional code is printed together.Two dimensional code can certainly be attached on file, the side pasted by label
Formula.
Two dimensional code, the transmitting carrier as file can certainly directly be used.That is a two dimensional code is exactly one
The file content of part electronic edition.So text document you can deposit in the mobile device of oneself and make directly as a picture
With.When you need to others show or others wish to obtain your file when, using mobile device parsing picture obtain
Obtain the file of electronic edition.Which has safe guarantee, and can prevent the loss of paper document, also solves usual life
Middle file problem inconvenient to carry.
File is veritified using equipment for customizing or app
Above-mentioned equipment for customizing is the equipment containing two dimensional code analysis program.Above-mentioned equipment for customizing can be divided into following 5 part;
Importation: for receiving two dimensional code;
Parsing part: the data of encryption are obtained for parsing two dimensional code containing two dimensional code analysis program;
Decryption portion: using the asymmetric code key in equipment, ciphertext data, and signature section letter is obtained according to integration rules
Breath;
Rating unit: it for comparing signature, ensures information security;
Part is presented: for rendering as a result, presentation mode can be the both sides' difference or tripartite's difference of multiplicity;
Device type can be with are as follows: pad, cell phone, customization android equipment etc..Above-mentioned cell phone can be utilization
App on cell phone is also possible to small routine etc..If it is small routine, need just to may be implemented in the case where network
File is veritified.
Two dimensional code is non-public technology, so two dimensional code has and can only be customized equipment parsing, it ensure that the private of information
It is sexual and authoritative.
Equipment for customizing contains the ciphering signature that file signs and issues unit, and the equally encryption label containing the unit in two dimensional code
Name.While the setting can guarantee the safety of equipment for customizing, accomplish the binding of equipment and two dimensional code, accomplishes the double-deck guarantor
Card.If there is criminal wants steal information or spurious information, then he must steal while generating code, oneself
Reforming equipment.This is practically impossible to for technological layer, is also huge in cost.
Verification procedure after decryption completion, can be naked eye comparing, be also possible to be directly realized by OCR comparison.It is first
First successful decryption is the authority for realizing data, then comparison data, then can prove the authentic and valid of data.So this method
The anti-fake of file may be implemented, protect the safety of information and file distribution unit.
And after decryption is completed, since other phases other than the content of file itself can also be contained in two dimensional code
Close information, such as unit telephone number.While can protect sensitive information, convenient acquisition of information is provided to related personnel.
The present invention is since all data are stored in two dimensional code, and analysis program is also in equipment.So the present invention can be with
Verification procedure is completed under off-line state.All Files content is all independently present in two dimensional code, and which achieves going for data
Centralization solves the problems, such as the high concurrent under network.Which also saves network and the costs of data simultaneously.
In conclusion the data medium acquisition methods for the two dimensional code that the embodiment of the present invention provides, have below beneficial to effect
Fruit:
(1) file of the invention based on two dimensional code can verify the file true and false in off-line case, strengthen it to ring
The adaptability in border, expands use scope;
(2) two dimensional code file of the invention can store the other information other than file, while protecting privacy information,
Reinforce being directed to for information to spread through sex intercourse;
(3) two dimensional code in file of the present invention is a information carrier, does not need the support of huge database, has saved number
According to cost, decentralization is realized, no data library risk of leakage improves safety.
Particular embodiments described above, to the purpose of the present invention, technical scheme and beneficial effects have been carried out further in detail
Describe in detail it is bright, it should be understood that above is only a specific embodiment of the present invention, the protection model being not intended to limit the present invention
It encloses, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
