It can determine that the first storage equipment is the target device of data to be restored.When do not recorded in digital wallet equipment second identifier and
When not recorded first identifier, digital wallet equipment can determine that digital wallet equipment itself is that the target of data to be restored is set
It is standby.
After the target device for determining data to be restored, since digital wallet equipment, the first storage equipment and second are deposited
It is stored in two non-targeted equipment in storage equipment: obtained first subdata, the second son is split to target data
Data and third subdata.Therefore, it is possible to by the first subdata, the second subdata and third subdata in target device to
The subdata of storage is restored.In this way, by any in digital wallet equipment, the first storage equipment and the second storage equipment
Two equipment can restore private key, improve the safety of private key.
In one implementation, digital wallet equipment obtain two non-targeted equipment in store the first subdata,
After second subdata and third subdata, subdata restoration principles can be based on, the first subdata, the second subnumber are directly utilized
Subdata to be stored in target device is restored according to third subdata.Wherein, subdata restoration principles are as follows: make pair
After the subdata stored needed for target device is restored, two one's share of expenses for a joint undertaking numbers are stored in each non-targeted equipment and target device
According to, and the subdata stored in any two equipment is not exactly the same.
For example, it when digital wallet equipment and the first storage equipment are non-targeted equipment, and is deposited in digital wallet equipment
The first subdata and the second subdata are contained, when being stored with the first subdata and third subdata in the first storage equipment, number
Wallet equipment can from the digital wallet equipment itself and first storage equipment in obtain: the first subdata, the second subdata and
Third subdata, and can determine that the second storage equipment subdata to be stored is the second subdata and third subdata.To,
Digital wallet equipment directly can extract the second subdata from three one's shares of expenses for a joint undertaking data obtained based on subdata restoration principles
With third subdata.Then, second subdata and third subdata the second storage is transferred to by the first storage equipment to set
In standby, to realize the recovery to subdata to be stored in the second storage equipment.
In another example when digital wallet equipment and the second storage equipment are non-targeted equipment, and stored in digital wallet equipment
There are the first subdata and the second subdata, when being stored with the second subdata and third subdata in the second storage equipment, digital money
Packet equipment can be obtained from the digital wallet equipment itself and the second storage equipment: the first subdata, the second subdata and the
Three subdatas, and can determine that the first storage equipment subdata to be stored is the first subdata and third subdata.To number
Word wallet equipment can based on subdata restoration principles directly be extracted from three one's shares of expenses for a joint undertaking data obtained first subdata and
Third subdata.Then, first subdata and third subdata are stored into the first storage equipment, to realize to first
Store the recovery of subdata to be stored in equipment.
In another implementation, digital wallet equipment is from the digital wallet equipment itself and the first storage equipment
It obtains:, can also be first with the first subdata, the second subdata after the first subdata, the second subdata and third subdata
Restore target data with third subdata.Then, target data is split using default secret partitioning algorithm, to divide
Obtain first object subdata, the second target subdata and third target subdata.
Wherein, first object subdata, the second target subdata and the third target subdata divided can be distinguished
It is identical as the first subdata, the second subdata and third subdata.It certainly, can also in order to further increase the safety of private key
So that first object subdata, the second target subdata and third target subdata and the first subdata, second that segmentation obtains
Subdata and third subdata be not identical, and this is also rational.
When first object subdata, the second target subdata and the third target subdata that segmentation obtains and the first subnumber
When according to, the second subdata and not identical third subdata, which can also utilize first object subdata, second
Target subdata replaces the first subdata, the second subdata stored originally.Then, by first object subdata and third mesh
Mark subdata is sent to the first storage equipment, the first object subdata and third target for receiving the first storage equipment utilization
Subdata replaces the first subdata and third subdata stored originally.In addition, the digital wallet equipment also pass through this first
It stores equipment and the second target subdata and third target subdata is sent to the second storage equipment, store the second storage equipment
The second target subdata and third target subdata.Then, it will record in digital wallet equipment: for dispersing storage target
The first identifier of first storage equipment of data and the second identifier of the second storage equipment.In this way, can be to the second storage equipment
Subdata to be stored is restored.Moreover, it is also possible to first object subdata, the second target subdata and third target
Data carry out dispersion storage, increase malicious user and steal the difficulty of private key, to improve the safety of private key, and then can protect
Demonstrate,prove the safety of assets in digital wallet.
Wherein, system composed by the digital wallet equipment, the first storage equipment and the second storage equipment can be referred to as such as
Hardware wallet 100 shown in Fig. 2.As shown in Fig. 2, the hardware wallet 100 includes: that digital wallet equipment 101, first stores equipment
102 and second store equipment 103.Wherein, which can pass through bluetooth module as shown in Figure 2 and first
It stores equipment 102 and carries out Bluetooth communication.First storage equipment 102 and the second storage equipment 103 can pass through plug electrical connection
Mode is communicatively coupled.
In addition, digital wallet equipment 101, first are deposited after the subdata of the storage needed for target device is restored
It is stored in storage equipment 102 and the second storage equipment 103: obtained first subdata, second is split to target data
Two one's share of expenses for a joint undertaking data in subdata and third subdata, and the subdata stored in any two equipment is not exactly the same.
Wherein, since digital wallet equipment 101, first stores in equipment 102 and the second storage equipment 103 in any appliance
The first subdata, the second subdata and third subdata will not be stored simultaneously.Thus, when digital wallet equipment 101, first stores
When any appliance in equipment 102 and the second storage equipment 103 is lost, private key safety reduction can be made.This is because when using
When any appliance in two equipment is lost at family again, private key can not then restore.
Wherein, the first subdata, the second subdata and third subdata can be digital wallet equipment utilization default secret
It is obtained that shared algorithm is split calculating to target data.Wherein, it can preferably be designed by privacy sharing algorithm: needle
To the fractionation scheme and recovery scheme of target data.It is subsequent to be based on the privacy sharing algorithm pair for this kind of partitioning scheme
First subdata, the second subdata and third subdata carry out data and restore to calculate, and recovery obtains target data.In addition, this kind
Partitioning scheme, malicious user could restore target data after needing to know the privacy sharing algorithm, improve malice and use
The difficulty of family recovery target data.
Certainly, the first subdata, the second subdata and third subdata are also possible to digital wallet equipment to target data
What progress obtained after directly cutting, this is also rational.For this kind of cutting mode, it is subsequent can be to the first subdata, second
Subdata and the second subdata are spliced, so as to restore to obtain target data.
Wherein, when target data is private key, digital wallet equipment can be split private key, wherein private key is pipe
Manage the exclusive evidence of the digital cash in digital wallet.When target data is private key encryption file, digital wallet equipment can be with
