The information such as easy magnitude.Therefore while data are really transparent in ensureing block chain, additionally it is possible to ensure the safety of data, thus
Own service can preferably be protected when using block chain by being conducive to user.
It should be understood that in the embodiment of the present application, the encryption of obscuring to hash may include various ways.
Optionally, in one implementation, the content that multiple hash form can be subjected to Hash calculation and obtains one
A hash.
For example, it is assumed that 4 in some block of block chain storages record corresponding hash be respectively HashA,
HashB, HashC and HashD, then the hash HashABCD=Hash (HashA+HashB+HashC after obscuring encryption
+ HashD), wherein function Hash () indicates Hash calculation function, such as MD5, SHA-1, SHA-256, SHA-384 and SHA-
512, etc..In bit coin system, the hash algorithm used is SHA-256.
Optionally, in another implementation, the content that any one hash can be divided into multiple portions is distinguished again
Hash calculation is carried out, the corresponding multiple hash of content of the multiple part are obtained.
For example, it is assumed that it is HashA that a storage in some block of block chain, which records corresponding hash, can incite somebody to action
HashA splits into HashA1 and HashA2, then carries out Hash respectively and handles to get HashA1 '=Hash (HashA1) is arrived,
HashA2 '=Hash (HashA2), HashA1 ' and HashA2 ' at this time, which obscure to HashA, to be obtained after encryption
Hash.Certainly, HashA can also be split into 3 parts, 4 parts or even more parts, specifically split into how many a portions
Point, how to split, is configurable.
Optionally, in another implementation, the content that multiple hash form can be separated into multiple portions
Content, and Hash calculation is carried out respectively to the content of each part, obtain the corresponding multiple Hash of content of the multiple part
Data.
For example, it is assumed that 4 in some block of block chain storages record corresponding hash be respectively HashA,
HashB, HashC and HashD, the content HashABCD=(HashA+HashB+HashC+HashD) of composition；It can incite somebody to action
HashABCD is divided into HashABCD1 and HashABCD2, then carries out Hash calculation respectively to HashABCD1 and HashABCD2 and obtain
Hash (HashABCD1) and Hash (HashABCD2), Hash (HashABCD1) and Hash (HashABCD2) are multiple portion
The corresponding multiple hash of content divided.
Furthermore, it is to be understood that the obfuscation schemes of the embodiment of the present application, can also carry out multilayer and obscure encryption, i.e., by one layer
Obscure the hash after encryption, then carry out one or more layers obscure encryption.Different layers obscure encryption
Algorithm, may be the same or different.
For example, it is assumed that 4 in some block of block chain storages record corresponding hash be respectively HashA,
HashB, HashC and HashD, then first layer obscures the Hash information HashABCD=Hash (HashA+HashB after encryption
+HashC+HashD)；It is Hash (HashABCD1) and Hash that the second layer, which obscures the hash after encryption,
(HashABCD2), wherein HashABCD=HashABCD1+HashABCD2.
Optionally, in another implementation, one or many fragment processing can be carried out to hash and/or is breathed out
It is uncommon to calculate.Specifically, fragment processing only can be carried out to obtain target hash to hash, by fragment processing and can also breathe out
The uncommon mode calculated, which combines, obscure encryption to hash to obtain target hash.

Degree is 64KB, then carries out fragment to hash according to the rule that each data slot size is 64KB；Alternatively, according to it is specified when
The long rule for carrying out fragment；For example, it is 1 second a length of when specified, then fragment is carried out according to the hash of interior storage per second, it is such as current
The hash stored in 1 second is a data slot, and the hash stored in lower 1 second is then next data slot.
Secondly, carrying out Hash calculation to each first data slot respectively, multiple second data slots are obtained.
Finally, obscuring encrypted target hash according to the determination of multiple second data slots.Specifically, can directly really
Fixed second data slot is target hash, can also carry out one or many fragments to the second data slot again and handle
And/or Hash calculation, finally obtain target hash.
In the present embodiment, lists and fragment processing is carried out, then to the data slice obtained after fragment to hash first
Duan Jinhang Hash calculation obscures encryption mode.Clearly as obscuring the diversity of encryption mode, add by obscuring
Close treated that target hash is difficult to be known by external user, it is thus ensured that the safety of target hash.

Fragment.It therefore, can will be included in each fragment when the target hash after fragment is stored respectively into the second block chain
Target hash is respectively as a business record storage into the second block chain.
In one embodiment, it can will obscure encryption mode to store into third block chain, and determine third block
The data of chain check that permission is only visible to the second designated user group.
Wherein, second designated user's group can be a user or multiple users.Second designated user's group can refer to first
It is identical or different to determine user group (i.e. for the first visible user group of block chain).Second designated user's group can be and the firstth area
The relevant staff of data stored in block chain/second block chain, such as the maintenance personnel of block chain, being somebody's turn to do (a little) user can be right
The hash stored in first block chain/second block chain is managed, such as storage, update operation；Alternatively, being somebody's turn to do (a little)
User can also be managed the encryption mode of obscuring stored in third block chain, such as storage, modification operation.
It in the present embodiment, is individually stored by the way that encryption mode will be obscured into third block chain, so that second is specified
User group, which is conveniently known, obscures encryption mode, to obscure encryption mode by acquisition to obtain the true of business datum
Real data.Also, it is external since third block chain is only to second designated user's group as it can be seen that other external users are invisible
User is difficult to know that is stored in third block chain obscures encryption mode, to be difficult to know the true number of business datum
According to, it is ensured that the safety of business datum.
In one embodiment, can also will obscure encryption mode to store into the first block chain, due to the first block
Chain is only to first designated user's group as it can be seen that other external users are invisible, therefore what is stored in the first block chain obscures at encryption
Reason mode is difficult to be known by external user, so that external user be made to be difficult to know the truthful data of business datum, it is ensured that business
