With module by every segment figure BTkTo several Cloud Server storages, specific step is as follows for distribution:
S1: several Cloud Servers of setting are labeled as Mi, i=1 ..., n；The corresponding free memory of Cloud Server Mi is denoted as NMi；
The corresponding position Cloud Server Mi is denoted as GMi；Setting user inputs the position note of information to be stored, storage level and storage time
GS；
S2: pass through GS and GMiCalculate Cloud Server and user input information to be stored the distance between difference and labeled as GL；
S3: formula is utilizedAcquire the preferential storage value Y of Cloud Server MiMi；Its
In, v1, v2 are preset ratio coefficient, and the value of v1, v2 are all larger than one；
S4: setting storage threshold value is denoted as Yb；Work as YMiCloud Server Mi is then labeled as choosing Cloud Server by > Yb；Cloud will be chosen
Server successively sorts according to preferential storage value is descending；
S5: and then the backup coefficient Q obtained；By every segment figure BTkQ parts of duplication is simultaneously labeled as backup figure QBTk；By every segment figure
BTkWith backup figure QBTkAccording to choosing the sequence of Cloud Server successively to store；It is embodied in BT1It is stored in preferential storage value
In most preceding corresponding Cloud Server；QBT1Preferential storage value is stored in take second place in corresponding Cloud Server；Backup figure QBTkStorage
It is complete and then successively store BT2、QBT2；And so on；
S5: every segment figure BT is countedkWith backup figure QBTkChoose storage location in Cloud Server and by its with choose service
Device number is sent to assignment storage module.
3. a kind of cloud information storage system based on data encryption according to claim 1, which is characterized in that described point
With memory module for storing every segment figure BTkWith backup figure QBTkIt is choosing position in Cloud Server and its is choosing service
Device numbers and generates corresponding unique identification instruction；Unique identification instructs several zero to nine natural numbers to constitute；Unique identification
Instruction is denoted as R1 R2 ... Rn, wherein R1, R2 ..., the value range of Rn be zero to nine natural number；Distribution storage mould
Block stores unique identification instruction sending value key verification module.
4. a kind of cloud information storage system based on data encryption according to claim 1, which is characterized in that described close
Key authentication module receives conversion extraction code and unique identification instructs and generate public key and private key is stored and sent on user terminal
It is shown；User terminal is sent to key verification module by input private key and is verified with public key, close after being proved to be successful
Key authentication module is by the corresponding conversion extraction code of public key and private key and unique identification instruction sends conversion memory modules and distribution is deposited
Store up module；Corresponding natural number identification code and conversion extraction code are sent to recovery module by conversion memory modules；Distribution storage mould
Root tuber obtains every segment figure BT according to unique identification instructionkWith backup figure QBTkChoosing storage location and choosing in Cloud Server
Middle server numbers and sends it to extraction module；Extraction module is according to the storage location chosen in Cloud Server and chooses clothes
Device number of being engaged in extracts corresponding every segment figure BTkOr backup figure QBTkAnd send recovery module；Recovery module is according to every segment figure
BTkOr backup figure QBTkBe restored to mark figure BT or backup mark figure QBT, then recovery module will identify figure BT or
Backup mark figure QBT is restored to transform graphical again, and transform graphical is restored to transform graphical BT according to interference factor again, turns
It changes figure BT and is restored to identification code set C according to graphic attribute, then according to the natural number identification code Ai inside identification code set C
It is reduced into the corresponding text of information to be stored, symbol and number, the information to be stored of reduction is sent to user's end by recovery module
End is shown；User terminal includes mobile phone, computer or tablet computer.
5. a kind of cloud information storage system based on data encryption according to claim 1, which is characterized in that described standby
Part analysis module is for calculating every segment figure BTkBackup coefficient Q；Steps are as follows for specific calculating:
S1: statistics is carried out to mark figure BT and gets corresponding byte-sized and is denoted as Ub；
S2: formula is utilizedAcquire backup coefficient Q；Wherein x1, x2 and x3 are preset ratio
Coefficient fixed value；QB is backup threshold value；
S3: when Q value is less than one, then without backup；When Q value is made of integer and decimal, then Q value value is integer.
