Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Embodiment one
The embodiment of the present invention one discloses a kind of blocking method of transaction record, and this method can be by hardware or/and software
It executes, please refers to shown in Fig. 1 comprising following steps:
110, transaction record is grouped with time sequencing according to preset range, every group of transaction record is denoted as transaction record
Group.
Transaction record is generated and is sorted according to time sequencing, therefore, is grouped sequentially in time, the rule of grouping
Predetermined period be can be with preset range for example as unit of the moon, be also possible to default transaction record item number, such as with 10
For unit, naturally it is also possible to be that each transaction record is used as a transaction record group.Application block chain is to transaction record group
When carrying out chain structure storage, each transaction record group is a block.Here transaction record can be all transaction
Record, is also possible to be labeled with important transaction record, can be the corresponding transaction record of a client, be also possible to own
Client or partial region (such as being divided with region) corresponding transaction record.
120, posterior transaction record group is combined in preceding timestamp, the object time is generated by hash algorithm
Stamp, the preceding transaction record group corresponding timestamp adjacent for posterior transaction record group in preceding timestamp, the mesh
Marking timestamp is described in the corresponding timestamp of rear transaction record group.
Chain structure storage is carried out to transaction record group in order to be formed, meanwhile, block preceding on chain is reinforced, is protected
Can not distorting for the historical trading of card from the near to the distant, in preferred embodiments of the present invention, passes through hash for preceding transaction record group
The timestamp (referred to as in preceding timestamp) that algorithm generates as the parameter in rear transaction record group, with posterior transaction record group into
It is generated by hash algorithm in the corresponding timestamp of rear transaction record group after row combination, i.e. the object time stabs, in preceding transaction record
Group is adjacent to rear transaction record group and sequentially in time, is located at before rear transaction record group in preceding transaction record group.With this
So that posterior transaction record group in being treated journey, is reinforced preceding All Activity record group, thus
Prevent distorting for transaction record.
For first group of transaction record group, there is no preceding transaction record group, therefore, corresponding timestamp is
The timestamp that the transaction record of first group of transaction record group itself is generated by hash algorithm, then using its timestamp as second
Group transaction record group input parameter, and so on, preceding timestamp and rear transaction record group combination can be it is more
Kind, such as will be before or after preceding timestamp is placed in the transaction record of rear transaction record group etc..
Timestamp includes two parts content, first is that transaction record group and timestamp are plucked by the data that hash algorithm generates
Want, i.e. hash code, the byte number of the hash code in each timestamp is identical, generally 256 bytes, second is that hash code generate or
The specific time being broadcasted or time sequencing, referred to as time series, certainly, time series can be used as a part of hash code,
That is time series and hash code totally 256 bytes.
It further include the encryption to timestamp in preferred embodiments of the present invention to guarantee the safety of data.That is: will
Posterior transaction record group (the transaction record content for referring to posterior transaction record group) is gone back with before preceding timestamp is combined
Include:
It is encrypted using public key by asymmetric arithmetic to described in preceding timestamp；By being matched with the public key
Private key verified, if verification pass through, posterior transaction record group is combined in preceding timestamp, is then passed through
Hash algorithm is generated in rear timestamp.
It is, of course, also possible to be: being encrypted using private key by asymmetric arithmetic to described in preceding timestamp；By with institute
The public key that private key is matched is stated to be verified, if verification pass through, by posterior transaction record group with preceding timestamp into
Row combination, is then generated by hash algorithm in rear timestamp.
For having carried out blocking processing and strengthened each block, compression can be carried out and realize returning for hard drive space
It receives, reduces the system resource of occupancy.Specifically:
Transaction record in default cutoff range is compressed by Merkle tree (Merkel tree) algorithm.It is default
Cutoff range can be default number of branches threshold value, such as preceding 1000 transaction records, be also possible to preset time threshold, such as preceding 12
A month transaction record.It is, of course, preferable to default cutoff range and preset range are corresponding, for example, preset range is default number of branches,
So default cutoff range uses default number of branches threshold value, and default number of branches threshold value is the integral multiple of default number of branches, and preset range is pre-
If the period, then default cutoff range uses preset time threshold, preset time threshold is the integral multiple of default number of branches.
This method encrypts the transaction record of user in financial system, and is calculated using preset range as dimension by hash
Method generates timestamp；Use for reference block chain technology in block chain thought, using in the hash timestamp of preceding block as in the rear block time
Stab generate important element, in subsequent block constantly to chain before block carry out reinforcing encryption, it is therefore prevented that transaction record is usurped
Change.
Embodiment two
Embodiment two discloses a kind of blocking device of transaction record of corresponding above-described embodiment, shown referring to figure 2.,
Include:
Grouping module 210, for transaction record to be ranked up sequentially in time, by the transaction record after sequence according to
Preset range is grouped, and every group of transaction record is denoted as transaction record group；
Generation module 220, it is raw by hash algorithm for posterior transaction record group to be combined in preceding timestamp
It is stabbed at the object time, the preceding transaction record group corresponding time adjacent for posterior transaction record group in preceding timestamp
Stamp, the object time stamp is to be described in the corresponding timestamp of rear transaction record group.
Embodiment three
