Abstract
The present invention discloses a relay transmission method of an optical label, comprising the following steps: (1) a relayer obtains image information of an original optical label by using a camera, and then decodes the image information of the original optical label, to obtain information carried by the original optical label; (2) the relayer adds a digital signature and incidental information of the relayer to the information carried by the original optical label, to obtain mixed information; and (3) the relayer generates image information of a new optical label according to the mixed information, a receiver decodes the image information of the new optical label, to obtain information carried by the new optical label, searches for the digital signature, determines whether the digital signature is consistent with a digital signature of the relayer that is pre-stored by the receiver, and when the digital signature found by the receiver is consistent with the digital signature of the relayer that is pre-stored by the receiver, the receiver considers that the information carried by the new optical label is correct, and completes relay transmission of the optical label. According to the method, an information obtaining distance is far, and the receiver can identify authenticity of received information.
Description
Technical field
The invention belongs to technical field of information transmission, relate to a kind of relaying transmission method, be specifically related to a kind of optical label
Relaying transmission method.
Background technology
Along with improving constantly of people's material life, businessman uses the mode of the Internet, TV and plane publication to enter mostly
Doing business the publicity of product, information transmission relatively costly, for reducing cost, businessman begins through the form of scanning Quick Response Code and carries out business
The publicity of product, then user is when scanning Quick Response Code, and the handheld device of user could must obtain in the scope certain with Quick Response Code
Take the information that Quick Response Code is carried, during simultaneously need to this Quick Response Code is forwarded to other people, then can not load the information of self, connect
Receipts person is when receiving the Quick Response Code that user sends over, it is impossible to distinguish the verity of this Quick Response Code.
Summary of the invention
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that the relaying transmission side of a kind of optical label
Method, this transmission method obtains the distant of information, and recipient is capable of identify that the true and false of the information received.
For reaching above-mentioned purpose, the relaying transmission method of optical label of the present invention comprises the following steps:
1) relaying person obtains the image information of former optical label by photographic head, then solves the image information of former optical label
Code obtains the information that former optical label is carried；
2) relaying person adds digital signature and the incidental information of self in the information that former optical label is carried, and must mix letter
Breath；
3) relaying person generates the image information of new optical label, then the image information by new optical label according to mixed information
Send to recipient, the image information of recipient receives relaying new optical label that person sends over, newer to receive
The image information of optical label is decoded, and obtains the information that optical label newly is carried, and the information carried from new optical label
Interior lookup digital signature, and judge that the digital signature of relaying person that whether this digital signature prestore with self is consistent, work as recipient
When the digital signature of the relaying person that the digital signature found prestores with self is consistent, assert the letter that this new optical label is carried
Breath is correct, completes the relaying transmission of optical label.
Step 3) in relaying person generate the image information of new optical label according to mixed information, then through server by new light
The image information of label sends to recipient.
The time during image information of described incidental information includes relaying person obtains former optical label and geography information.
Optical label includes signal array, and described signal array is by the some signal luminescent device groups in formation arranged distribution
Become, when encoding, first the information of precoding is converted into binary number, wherein, in binary number and signal battle array
A signal luminescent device in row is corresponding, when any one position in binary number is 0, then and the signal luminous organ of its correspondence
Part is closed, when any one position in binary number is 1, then and the signal luminescent device work of its correspondence.
Optical label also includes three location mark luminescent devices of the positional information for determining signal array.
Step 1) concrete operations be: relaying person obtains the image information of former optical label by photographic head, then at former cursor
The image information signed is searched described three location mark luminescent devices, so that it is determined that go out the positional information of signal array, intercepts
The image information of signal array, and the image information of signal array is converted into binary number, binary number described in further decoding,
The information that former optical label is carried.
The method have the advantages that
The relaying transmission method of optical label of the present invention, when concrete operations, carries to be publicized by optical label
Information, relaying person obtains the image information of former optical label by photographic head simultaneously, then is decoded, and can obtain former optical label institute
The information of carrying, thus realize remotely reading and identifying of information, relaying person is when sending information to recipient, by the number of self
Word signature joins in the information that former optical label is carried with incidental information, forms mixed information, then further according to mixed information
Generating the image information of new optical label, then the image information of new optical label is forwarded to recipient, recipient is to new light
The image information of label is decoded, then is authenticated digital signature therein, the information that i.e. can obtain decoding true
Puppet, simple to operate, there is the most wide application prospect.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail:
With reference to Fig. 1, the relaying transmission method of optical label of the present invention comprises the following steps:
