Description
Technical field
The present invention relates to block chain technical fields, in particular to publication executes authenticating party offline in a kind of block chain
Method.
Background technique
Existing block chain data press the block chain data of Node distribution, each node storage full dose or part.When block chain
In when having multiple nodes, each node saves a independent data, and data are stored on the physical hard disk of this node, this
Storage organization can not simply provide across a network access；Each module close-coupled in existing block chain software simultaneously, is all deployed in
It on same node, when run-time error occurs, can not be monitored for wherein single module, and can not be wrong for there is operation
Module accidentally carries out corresponding processing, difficult so as to cause the O&M of block chain.When for there is no network, how block chain is carried out
The certification of data is the technical problem for needing urgently to solve.
Summary of the invention
The invention proposes issuing to execute authentication method offline in a kind of block chain, include the following steps:

The request of issue object document；(i) make a reservation for the id information of distribution destination and registration, (II) reference paper is obtained from data
Value, and (iii) reference documents data include corresponding to the scheduled file for issuing destination document to dedicated block chain number
According to the character data of the content in library, then a specific cryptographic Hash, generates in the first particular Hash value；
(b) document management server obtains by being applied to hash function about the id information of offline document and from comparing
Value that document data obtains and the second particular Hash value for generating, by using represent hashed value or second obtain it is second specific
Hashed value indicates to add the hashed value or processing generated by from common block chain database by using this method and the ID of transmission
First representative of cryptographic Hash and the value that obtains, carry out first it is representative executes processing, for obtaining the Kazakhstan obtained by processing
Uncommon value；Also, the described first hashed value indicated or the first value of hashed value or second expression of second expression, processing
Described first represents the hash of hashed value and using treated value generation document authentication end value.
The method, middle first particular Hash value that generates of the step (a) specifically include: (i) ID is described for issuing
The file destination of predetermined information, and (ii), by using hash function from1The value obtained in reference paper data generates
Hash-and by calculate at least one matched adjacent hashes value of the first particular Hash value or by processing first represent dissipate
Value that train value obtains and first representing hashed value and be registered in Rake block chain database for generating, it is by corresponding to this to TxID
Addition management, document management server, for the certification request information issued offline, id information and the comparison for off-line files
Document data-compare document wherein, document management server includes: the image data that (i) extracts offline document, and passes through word
It accords with identification technology (OCR) and extracts character data；(ii) character data extracted from the image data of offline document is received, to obtain
The character data of document data must be compared.
The method, step (b), the representative hashed value of the second of generation or the second representative hashed value will be with the first generation
Table hashed value or the first representative hashed value and the value obtained is compared.
The method, by calculating, matched at least one is adjacent with the second particular Hash value and the second particular Hash value
Hashed value generates second generation table hashed value.
The method, the method for second particular Hash value and the hashed value for calculating or calculating, is assigned to brother
Node and the node of the second particular Hash value are assigned to support, and calculate for second particular Hash value and by hashed value
Calculated value out is assigned to the hashed value of the brother of node, which is assigned to the father node of the node,
If father node is the root node for merging tree, the hashed value for distributing to father node is used as from public using the information of transmission
The second of block chain database represents hashed value, if father node is not the root node for merging tree, distributes to the hash of father node
Value is arranged to the second particular Hash value and repeats.

The request of issue object document；(i) make a reservation for the id information of distribution destination and registration, (II) reference paper is obtained from data
Value, and (iii) reference documents data include corresponding to the scheduled file for issuing destination document to dedicated block chain number
According to the character data of the content in library, then a specific cryptographic Hash, generates in the first particular Hash value；
(b) document management server obtains by being applied to hash function about the id information of offline document and from comparing
Value that document data obtains and the second particular Hash value for generating, by using represent hashed value or second obtain it is second specific
Hashed value indicates to add the hashed value or processing generated by from common block chain database by using this method and the ID of transmission
First representative of cryptographic Hash and the value that obtains, carry out first it is representative executes processing, for obtaining the Kazakhstan obtained by processing
Uncommon value；Also, the described first hashed value indicated or the first value of hashed value or second expression of second expression, processing
Described first represents the hash of hashed value and using treated value generation document authentication end value.
The method, middle first particular Hash value that generates of the step (a) specifically include: (i) ID is described for issuing
The file destination of predetermined information, and (ii), by using hash function from1The value obtained in reference paper data generates
Hash-and by calculate at least one matched adjacent hashes value of the first particular Hash value or by processing first represent dissipate
Value that train value obtains and first representing hashed value and be registered in Rake block chain database for generating, it is by corresponding to this to TxID
Addition management, document management server, for the certification request information issued offline, id information and the comparison for off-line files
Document data-compare document wherein, document management server includes: the image data that (i) extracts offline document, and passes through word
It accords with identification technology (OCR) and extracts character data；(ii) character data extracted from the image data of offline document is received, to obtain
The character data of document data must be compared.
The method, step (b), the representative hashed value of the second of generation or the second representative hashed value will be with the first generation
Table hashed value or the first representative hashed value and the value obtained is compared.
The method, by calculating, matched at least one is adjacent with the second particular Hash value and the second particular Hash value
Hashed value generates second generation table hashed value.
The method, the method for second particular Hash value and the hashed value for calculating or calculating, is assigned to brother
Node and the node of the second particular Hash value are assigned to support, and calculate for second particular Hash value and by hashed value
Calculated value out is assigned to the hashed value of the brother of node, which is assigned to the father node of the node,
If father node is the root node for merging tree, the hashed value for distributing to father node is used as from public using the information of transmission
The second of block chain database represents hashed value, if father node is not the root node for merging tree, distributes to the hash of father node
Value is arranged to the second particular Hash value and repeats.
Although describing the present invention by reference to various embodiments above, but it is to be understood that of the invention not departing from
In the case where range, many changes and modifications can be carried out.Therefore, be intended to foregoing detailed description be considered as it is illustrative and
