Abstract
The invention discloses the storages based on block chain technology to record mould group, including several Distributed Storage modules, data allocation module, the Distributed Storage module is mainly made of data block and chained record transmission module, the data allocation module is used to that storing data to be distributed to several Distributed Storage modules to be described, again by the chained record transmission module by the storing data mean allocation into data block, the data block is connected by chained record transmission module.Common data storage is linear, and the storage mode in the present invention is network type, by the data block in several Distributed Storage modules come storing data, when extracting or deleting to data, it needs chained record transmission module to cooperate, complete data just can be obtained after the data of fragment type are integrated.
Description
Technical field
The present invention relates to block chains, and in particular to the storage based on block chain technology records mould group.
Background technique
Block chain is the novel of the computer technologies such as Distributed Storage, point-to-point transmission, common recognition mechanism, Encryption Algorithm
Application model.So-called common recognition mechanism is that the mathematics calculation established between different nodes and trust, obtain equity is realized in block catenary system
Method.
The safety that storage mode is improved by block chain is present developing direction, by single, popular go
The heart stores to realize, can not improve safety in itself；It only can't by autonomy, opening and anonymity
Effective is storage record to provide safeguard protection.
So increasing a storage record mould group while being based on block chain technology to play the role of supervision, actively remembering
Address book stored information improves safety.
Summary of the invention
The present invention provides the storage record mould based on block chain technology to enhance safety, the reliability of the prior art
Group improves the stored security reliability of storage by distributed storage.
The present invention is achieved through the following technical solutions:
Storage based on block chain technology records mould group, including several Distributed Storage modules, data allocation module,
The Distributed Storage module is mainly made of data block and chained record transmission module, and the data allocation module is used for
Storing data is distributed into several Distributed Storage modules to be described, then is deposited by the chained record transmission module by described
Data mean allocation is stored up into data block, the data block is connected by chained record transmission module.
Further, in order to reinforce the confidentiality that data store, the Distributed Storage module further includes asymmetric
Encrypting module, the asymmetric encryption module is for encrypting the chained record transmission module.
Further, the data allocation module encodes each data while distributing storing data.
Further, the coding is the Codabar code obtained by Hash calculation, and assigns the code to the storage
The tail end of data.
Further, several Distributed Storage modules are connected to the network by P2P.
Compared with prior art, the present invention having the following advantages and benefits:
The present invention is based on the storages of block chain technology to record mould group, is improved using the characteristics of block chain Point-to-Point Data Transmission
Safety when data are transmitted is improving reliability by distributed storage mode, in a data block damage or is stolen
When, other dropout of data block can be prevented by cutting off mutual connection.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to embodiment, the present invention is made
Further to be described in detail, exemplary embodiment of the invention and its explanation for explaining only the invention, are not intended as to this
The restriction of invention.
Embodiment
Storage based on block chain technology records mould group, including several Distributed Storage modules, data allocation module,
The Distributed Storage module is mainly made of data block and chained record transmission module, and the data allocation module is used for
Storing data is distributed into several Distributed Storage modules to be described, then is deposited by the chained record transmission module by described
Data mean allocation is stored up into data block, the data block is connected by chained record transmission module.Common data storage is
It is linear, and the storage mode in the present invention is network type, by the data block in several Distributed Storage modules come
Storing data needs chained record transmission module to cooperate when extracting or deleting to data, and the data of fragment type are carried out
Complete data just can be obtained after integration.
The Distributed Storage module further includes asymmetric encryption module, and the asymmetric encryption module is used for institute
Chained record transmission module is stated to be encrypted.
The data allocation module encodes each data while distributing storing data.
The coding is the Codabar code obtained by Hash calculation, and the code is assigned to the tail of the storing data
End.
Several Distributed Storage modules are connected to the network by P2P.
It, must be in the storage location of f (K) if there is the record equal with keyword K in structure.It is not required to compare as a result,
Compared with can directly obtain institute Cha Jilu.This corresponding relationship f is referred to as hash function (Hash function), is built in advance by this
Vertical table is hash table.
Same hash address, i.e. key1 ≠ key2 be likely to be obtained to different keywords, and f (key1)=f (key2), this
Kind phenomenon claims to collide.Keyword with same functions value is referred to as synonym for the hash function.In conclusion according to dissipating
Array function H (key) and the method for processing conflict by a set of keyword image to a limited continuous address set (section),
And using " as " of keyword in address set as the storage location being recorded in table, this table is just known as hash table, this is reflected
It makes a list or hashes as process is known as hashing, resulting storage location claims hash address.
If for any one keyword in set of keywords, hashed function mapping any one ground into address set
The probability of location be it is equal, then such hash function is referred to as uniform hashing function (Uniform Hash function), here it is
Keyword is set to obtain one " random address " by hash function, to reduce conflict.
All hash functions are all just like next fundamental characteristics: if two hashed values are different (according to same letter
Number), then being originally inputted for the two hashed values is also different.This characteristic is the deterministic knot of hash function
Fruit.But then, outputting and inputting for hash function is not that correspondingly, if two hashed values are identical, two are inputted
Value is likely to identical, but both not blood sure certain equal (being likely to occur Hash collision).Some data are inputted to calculate
Hashed value out, then part changes input value, a hash function with strong aliasing characteristics can generate one it is entirely different
Hashed value.
Typical hash function has unlimited adopted domain, such as byte character string and the limited codomain of random length, than
Such as the Bit String of regular length.In some cases, hash function can be designed to the domain and codomain with same size
Between one-to-one correspondence.One-to-one hash function also referred to as arranges.Invertibity can be by using a series of for input
Reversible " mixing " operation of value and obtain.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not intended to limit the present invention the foregoing is merely a specific embodiment of the invention
Protection scope, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
