In the mode that former data are encrypted to global storage, security risk is reduced, this improves the security of data storage.
Based on above-mentioned hardware configuration, data processing method embodiment of the present invention is proposed.
With reference to Fig. 2, Fig. 2 is the flow diagram of data processing method first embodiment of the present invention.
In the first embodiment, the data processing method comprises the following steps：
Step S10, former data to be stored are handled, and generate more one's share of expenses for a joint undertaking data；
When needing what is loaded on the electronic equipments such as memory mobile terminal, PC (personal computer, personal computer)
The corresponding sensitive data of application software and the key for sensitive data to be encrypted are when data, in order to improve number
According to the security of storage, in the present embodiment, directly these data are not stored, but these data are split into more
Part is separately stored.For the ease of description, hereafter by sensitive data, key etc., these data are known as former data.
Specifically, when needing to store former data, former data is handled first, are such as torn open former data
Divide and calculate, generate corresponding more parts of data.For the ease of description, the data generated after hereafter former data are split are known as subnumber
According to.Alternatively, corresponding more one's share of expenses for a joint undertaking data can be generated by a variety of method for splitting.In the following, two kinds therein are enumerated to former number
According to the method split calculating and generate corresponding more one's share of expenses for a joint undertaking data.
First, in the method, the step S10 includes：
The former data are split into the more parts of subdatas by step a using Lagrange's interpolation.
In the method, fractionation calculating is carried out using Lagrange's interpolation, generates corresponding more one's share of expenses for a joint undertaking data.For example,
Assuming that Lagrange interpolation polynomial is：
F (x)=(a0+a1x+a2x2+……+an-1xn-1) mod q, wherein a1、a2……an-1For multinomial coefficient, a0For
Former data to be stored, q are Big prime.
Using the Lagrange interpolation polynomial, optional n mutually different nonzero integer x0、x1、x2……xn-1, calculate
Corresponding f (x), so as to obtain corresponding y0、y1、y2……yn-1.So, accordingly (x0, y0)、(x1, y1)、(x2, y2)、……
(xn-1, yn-1) it is former data a0It is split rear corresponding more one's share of expenses for a joint undertaking data.
2nd, in the method, the step S10 includes：
Step b, according to the former data, generates multiple random numbers；
Step c, carries out XOR operation by the multiple random number and the former data, obtains operation result one by one；
Step d, using the operation result and multiple random numbers as described more parts corresponding with the former data
Subdata.
In the method, according to former data to be stored, the corresponding multiple and close random number of former size of data is generated.
Then, these random numbers and former data are subjected to XOR operation one by one, obtain operation result.Operation result and these random numbers
Rear corresponding more one's share of expenses for a joint undertaking data are split for former data.For example, it is assumed that n-1 random number b of generation1、b2……bn-1, by random number
b1、b2……bn-1And the former common n number of data carries out XOR operation one by one, i.e.,：First two data in the n number are carried out different
Or, obtained result is subjected to exclusive or with the 3rd number again again, and so on, finally obtain corresponding operation result bn, then b1、
b2……bn-1、bnRear corresponding more one's share of expenses for a joint undertaking data are split for former data.
It is understood that in addition to the above-mentioned two methods enumerated, can also be calculated by other method for splitting
Generate corresponding more one's share of expenses for a joint undertaking data.In the present embodiment, specific used method for splitting is not limited.
Step S20, configures multiple and different storage address, wherein, the number of the storage address is no less than the subnumber
According to number；
Every one's share of expenses for a joint undertaking data, are stored in different storage address by step S30 respectively.
Split when to former data, after obtaining corresponding more one's share of expenses for a joint undertaking data, according to more one's share of expenses for a joint undertaking data, in electronic equipment
A free memory is distributed in corresponding memory space.For example, the storage configured in the corresponding application software of former data
A free memory is distributed in space.Wherein, the size of the free memory preserves more one's share of expenses for a joint undertaking data enough.And it is based on
The free memory, configures corresponding multiple storage address, each storage address is in the free memory.Wherein,
The number of the storage address of configuration is no less than the number of subdata.For example, it is assumed that the number of subdata is n, the storage of configuration
The number of location is m, then m >=n.
Afterwards, according to the multiple storage address configured, every one's share of expenses for a joint undertaking data are stored in different storage address respectively.
Since the number of storage address is no less than the number of subdata, thereby it can be assured that all subdatas can be stored in accordingly
Storage address in.Specifically, when the storage address number of configuration is identical with the number of subdata, then just respectively each
Corresponding different subdatas are stored in a storage address.When the number of the storage address of configuration is more than the number of subdata, into
One step, after the step S30, further include：
Step e, the storage interference data in the storage address that residue does not store the subdata.
Further, in order to further improve the security of data storage, it is also provided with disturbing accordingly in the present embodiment
Data.Also, when configuring storage address, the number of storage address is set to be more than the number of subdata.In this way, will be per one's share of expenses for a joint undertaking
After data are stored in different storage address, also part storage address is vacant.At this time, subdata is not stored in residue
Corresponding interference data are stored in storage address, so as to form interference, the risk that data are stolen is reduce further, improves
The security of data storage.
For different application software, since the memory space of its correspondence distribution is different, correspondingly, in step S20
The multiple storage address configured just differ.Therefore, will not be right even if the storage address of some application software is compromised
Other application software impact.
Scheme provided in this embodiment, by the way that former data to be stored are split into more one's share of expenses for a joint undertaking data, and configures corresponding
Every one's share of expenses for a joint undertaking data, are stored among different storage address by multiple storage address respectively, it is achieved thereby that former data is scattered
Storage.Compared to the mode that former data are encrypted to global storage, security risk is reduced, this improves data storage
Security.
Further, as shown in figure 3, proposing data processing method second embodiment of the present invention based on first embodiment,
In the present embodiment, before the step S20, further include：
Step S40, judges whether the byte length of the former data is less than preset byte length.If so, described in then performing
Step S10；If it is not, then perform step S50；
Step S50, generates more piece data to be split, wherein the byte long of the data to be split by the former data processing
Degree is less than the preset byte length；
Data to be split described in every section are carried out fractionation calculating by step S60 respectively, corresponding more to generate the former data
One's share of expenses for a joint undertaking data.
In the present embodiment, a preset byte length is pre-set.For example, it is 256 bytes to set the preset byte length,
The preset byte length can flexibly be set according to actual conditions, is not limited in the present embodiment.During in order to reduce calculating
Between and memory consumption, before fractionation calculating is carried out to former data, first determine the byte length of former data, and by former data
Byte length judges whether the byte length of former data is less than preset byte length compared with preset byte length.It is if former
The byte length of data is less than preset byte length, namely illustrates that the byte length of former data is not long.At this time, directly to original
Data are handled, and such as former data are carried out with fractionation calculating, obtain corresponding more one's share of expenses for a joint undertaking data.Specific calculating process such as first is real
Apply described in example, details are not described herein.
If the byte length of former data is greater than or equal to preset byte length, namely the byte long of the former data of explanation is spent
It is long.At this time, former data are divided into more piece data to be split.Wherein, it is each save data to be split byte length it is respectively less than pre-
If byte length.Then, data to be split are saved carry out fractionation calculating to every respectively, generate corresponding subdata.All subdatas
Constitute the corresponding more one's share of expenses for a joint undertaking data of former data.
For example, according to Lagrange's interpolation to former data a0Fractionation calculating is carried out, then data a more former first0Word
Save the size of length and preset byte length.If former data a0Byte length be less than preset byte length, then it is bright using glug
Day, interpolation method was to former data a0Fractionation calculating is carried out, obtains former data a0Corresponding more one's share of expenses for a joint undertaking data.Otherwise, if former data a0's
Byte length is greater than or equal to preset byte length, then by former data a0It is divided into more piece data a to be split0'、a0”、…….Its
In, often save data a to be split0'、a0" ... byte length be less than preset byte length.Then, using Lagrange's interpolation
Method saves data a to be split to every0'、a0" ... fractionation calculating is carried out, obtains often save data a to be split respectively0'、a0”、……
Corresponding subdata, needs to be split data a0'、a0" ... corresponding subdata forms former data a0Corresponding subdata.
Further, in the multinomial coefficient a of Lagrange interpolation polynomial1、a2……an-1In, at least there are more than one
The byte length of binomial coefficient is not less than former data a0Byte length.In this manner it is possible to ensure former data a0It is not exposed, from
And further increase the security of data storage.
Further, nonzero integer x is being chosen0、x1、x2……xn-1When, corresponding selection condition is set.Such as x0、x1、
x2……xn-1Byte length be 1 byte.So, it is possible to reduce calculate time and memory consumption.
Time and memory consumption, selected x are calculated in order to further reduce0、x1、x2……xn-1Sum not
More than corresponding preset value.For example, if it is 17, x to set the preset value0、x1、x2……xn-1Sum be no more than 17.If x0、
x1、x2……xn-1Sum exceed preset value, then can cause to calculate the time too long, the increase of the space of consumption.
Scheme provided in this embodiment, when the byte length of former data is less than preset byte length, directly by former data
Fractionation calculating is carried out, obtains corresponding subdata；And when the byte length of former data is not less than preset byte length, first by original
Data be divided into byte length be less than preset byte length more piece data to be split, then respectively to it is every save data to be split into
Row, which is split, to be calculated, and generates the corresponding subdata of former data, time and memory consumption are calculated so as to reduce.
Further, data processing method 3rd embodiment of the present invention is proposed based on first embodiment or second embodiment,
In the present embodiment, the step S20 includes：
Step f, obtain the former data correspond to electronic equipment UUID (Universally Unique Identifier,
Universally Unique Identifier)；
Step g, multiple storage address are obtained according to the UUID.
In the present embodiment, by obtaining the UUID of electronic equipment, corresponding storage address is configured further according to the UUID.Tool
Body, storage address can be configured according to UUID by following three mode：
1st, according to the UUID of electronic equipment, corresponding storage address is configured using hash algorithm.Specifically, it is right first
UUID carries out Hash computings, obtains the first numerical value H0；Then to H0Hash computings are carried out, obtain second value H1；Successively according to upper
Mode is stated, Hash computings are carried out to a upper numerical value, obtain corresponding next numerical value, until final calculate obtains Hn.Assuming that
The memory space of distribution can be used for storage m one's share of expenses for a joint undertaking data, the H that progress Hash computings are obtained1、H2、……HnM is asked respectively
It is remaining, calculate and obtain corresponding each storage address.If in complementation calculating process, the result of calculation that duplicates, then continue into
Row Hash computings and then complementation, until the different storage address of number required for final calculating acquisition.
2nd, according to the UUID of electronic equipment, calculated by quadratic sum complementation to configure corresponding storage address.Specifically, it is false
If the memory space of distribution can be used for storage m one's share of expenses for a joint undertaking data, first by UUID progress square, and m complementations are calculated, obtain first
A storage address；And then first storage address progress square of gained will be calculated, and m complementations are calculated, obtain second
Storage address；Corresponding storage address is calculated in the manner described above successively, until obtaining corresponding each storage address.
3rd, according to the UUID of electronic equipment, corresponding storage address is configured by being encrypted to UUID.Specifically, adopt first
UUID is encrypted with the UUID of electronic equipment, obtains first storage address Addr1, wherein, specific cipher mode can use existing
Have to data ciphering method, therefore details are not described herein；Then Addr1 is encrypted using Addr1 again, obtains second storage
Address Addr2；Corresponding storage address is calculated in the manner described above successively, until obtaining corresponding each storage address.
For different electronic equipments, since its UUID is different, correspondingly, what is configured in step S20 multiple deposits
Storage address just differs.Therefore, even if application software and the corresponding overall quilt " packing " of former data are copied to other electronics and set
It is standby upper, it can not also recover correct storage address.
The present embodiment stores multiple storage address of subdata, and by obtaining the UUID of equipment, UUID is carried out at calculating
Reason obtains, be encrypted between multiple storage address so that independently of each other it is unaffected, even if which part storage address
Identified, corresponding subdata is stolen, it is also difficult to finds other storage address.In this way, storage address is generated in a manner of safer,
Further increase the security of data storage.
Further, as shown in figure 4, after the step S30, further include：
Step S70, when receiving former data acquisition instruction, obtains the storage address for being all stored with the subdata,
And all subdatas are obtained from the storage address respectively；
Step S80, all the subdata will carry out composite calulation, generate the former data.
In the present embodiment, when user needs to obtain the former data of storage, corresponding former data acquisition operations are performed.Example
Such as, the relevant operation to former data is performed, so as to trigger corresponding former data acquisition instruction.Refer to when receiving the original data acquisition
When making, obtain all be stored with the storage address that the original data correspond to subdata first.For example, according to above-mentioned in the former data of storage
During determine storage address mode, recalculate and determine multiple storage address.Then, from definite whole storage address
It is middle to obtain corresponding whole subdatas.
After each subdata is got, according to former data method for splitting carry out inverse operation, also will each subdata into
Row composite calulation, so as to obtain former data.If for example, in the former data a of storage0When, it is to use Lagrange's interpolation by former number
According to a0Split into each subdata (x0, y0)、(x1, y1)、(x2, y2)、……(xn-1, yn-1), then correspondingly, getting each height
Data (x0, y0)、(x1, y1)、(x2, y2)、……(xn-1, yn-1) after, according to the following formula：
Lj=x0/(x0-xj)*x1/(x1-xj)*……xi/(xi-xj)*……*xn-1/(xn-1-xj) (the n- of j=0,1,2 ...
1, and i ≠ j)
L is calculated successively0、L1、L2、……Ln-1；Then, former data a is calculated according to the following formula0：
a0=y0*L0+y1*L1+……+yn-1*Ln-1。
And for example, it is to use random number b if in the former data of storage1、b2……bn-1And former data carry out XOR operation one by one
Obtain operation result bn, the corresponding subdata of former data is b1、b2……bn-1、bn, then correspondingly, each subdata b is being got1、
b2……bn-1、bnAfterwards, by each subdata b1、b2……bn-1、bnExclusive or one time, reverse operation obtain former data.
If the corresponding subdata of former data is obtained it is understood that being calculated using Lagrange's interpolation, then extensive
After restored data, the multinomial coefficient of Lagrange interpolation polynomial can be updated.In this way, according to the Lagrange after renewal
When interpolation polynomial again splits former data, obtained subdata by with difference before.Or if using
Random number splits former data, then after extensive restored data, can update random number.In this way, according to new random number
And former data carry out XOR operation, finally obtained subdata also by with difference before.Therefore, for same former number
According to the subdata obtained after being split can be updated, namely the secret after fractionation can be updated.Cause
This so that the storage of former data is very flexible, so as to further increase the security of data storage.
Former data are being split into each subdata by scheme provided in this embodiment, and are stored respectively in different storages
After location, when needing to obtain former data, the storage address of subdata is stored with by obtaining, and acquisition is each from storage address
Subdata, then carries out composite calulation, so as to obtain former data by each subdata.The recovery for realizing former data obtains, namely
Realize the safe handling of data.
In addition, the embodiment of the present invention also proposes a kind of computer-readable recording medium, the computer-readable recording medium
On be stored with data processor, following operation is realized when the data processor is executed by processor：
Former data to be stored are handled, generate more one's share of expenses for a joint undertaking data；
