Under the premise of can be with combination of interactions.
Embodiment 1, with reference to Fig. 1, a kind of electronics license storage method based on block chain, comprising:
The electronics license that step 1, the first number of distribution are stored to needs；
Step 2 will need the electronics license stored to change into picture format, obtain supergraph piece；
Step 3 successively cuts supergraph piece, obtains N sub-pictures；
Step 4, the label number that the first number and characterization are cut to sequence are associated with N sub-pictures respectively；
Step 5, the N number of memory block of creation；
Step 6 is stored in what the N after association sub-pictures were distributed in N number of memory block；Wherein, N is natural number, N
≥2。
Specifically, the first number is for distinguishing different electronics licenses to needing to store the first number of electronics license distribution
Identifier, first number can be a numeric string.In order to enable electronics license is unitized, so to the lattice of electronics license
Formula is uniformly converted into picture format, obtains supergraph piece.Wherein, as optimization, the format of supergraph piece is jpg format, because of jpg lattice
Formula has the characteristics that high-quality, compression ratio is high, therefore, the format of supergraph piece is changed into jpg format, is conducive to subsequent storage.
Supergraph piece is cut, to obtain N sub-pictures, wherein by the method that supergraph piece is cut include: to utilize rectangular mold
Plate successively cuts supergraph piece from left to right.Wherein, the length of rectangle template is adapted with the width of supergraph piece, the rectangle template
Width is 20-50 pixel.Optimal, the width of rectangle template is 30 pixels.Supergraph piece is broken the whole up into parts in this way,
Obtain N number of sub-pictures.Certainly, by the method for supergraph piece cut can also there are many kinds of, for example special-shaped sanction can be used
The template cut carries out irregular cut to supergraph piece.
In step 4, the side label number that the first number and characterization cut sequence being associated with N sub-pictures respectively
Method includes: to form character string with the label number that the first number and characterization cut sequence, is named with the character string to sub-pictures,
Complete association.
When being cut from left to right to supergraph piece, the label number of first sub-pictures cut is " 1 ", is cut
The label number of second obtained sub-pictures is " 2 ", and so on, i.e. the label number of N sub-pictures is " N ".At this point, by
One number with label number forms character string to name corresponding sub-pictures, i.e., names in the form of " the first number+label number "
Sub-pictures.For example, the naming method of first sub-pictures is " the first number+1 ".In this way, the pass of sub-pictures is completed
Connection.
After association, so that it may be stored in what N number of sub-pictures were distributed in N number of memory block.Complete storing process.When
So, in order to save memory space, after association, N number of sub-pictures can be compressed respectively, then by compressed son
Picture storage.
The disclosure it is creative electronics license is converted into picture format, and by pictured whole being stored in not for zero cloth
In same memory block.Electronics license is stored by the thought of distributed storage, global storage is avoided and electronics license is caused to divulge a secret
Situation.
Wherein, using the first number of distribution as the unique identification of electronics license.It can number by first from storage
Sub-pictures are searched out in block, electronics license is successively then reconstructed by the label number on sub-pictures, complete storage extraction process.
With reference to Fig. 2, a kind of electronics license storage device based on block chain, comprising: distribution module, picture conversion module,
Cut module, relating module, memory block creation module and memory module.
Specifically, distribution module is to needing to store the first number of electronics license distribution, the first number is for distinguishing difference
The identifier of electronics license, the first number can be a numeric string.In order to enable electronics license unitizes, picture modulus of conversion
Block is converted into picture format to the uniform format of electronics license, obtains supergraph piece.Wherein, the format of supergraph piece is jpg format, because
Have the characteristics that high-quality, compression ratio is high for jpg format, therefore, the format of supergraph piece is changed into jpg format, is conducive to below
Storage.
It cuts module to cut supergraph piece, to obtain N sub-pictures, wherein cut module and carry out supergraph piece
The method cut includes: successively to be cut from left to right using rectangle template to supergraph piece.Wherein, the length of rectangle template and supergraph piece
Width be adapted, the width of the rectangle template is 20-50 pixel.Optimal, the width of rectangle template is 30 pixels.
Supergraph piece is broken the whole up into parts in this way, obtains N number of sub-pictures.
The label number that first number and characterization cut sequence is associated with N sub-pictures by relating module respectively, wherein
Associated method includes: to form character string with the label number that the first number and characterization cut sequence, with the character string to sub-pictures
It is named, completes association.
When being cut from left to right to supergraph piece, the label number of first sub-pictures cut is " 1 ", is cut
The label number of second obtained sub-pictures is " 2 ", and so on, i.e. the label number of N sub-pictures is " N ".At this point, by
One number with label number forms character string to name corresponding sub-pictures, i.e., names in the form of " the first number+label number "
Sub-pictures.For example, the naming method of first sub-pictures is " the first number+1 ".In this way, the pass of sub-pictures is completed
Connection.
Memory block creation module is for creating N number of memory block；
Memory module is used for being stored in N sub-pictures distributions after association in N number of memory block；Wherein, N is certainly
So number, N >=2.
