It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Fig. 1 shows the flow diagram of the lottery rewarding method according to an embodiment of the invention based on block chain.
As shown in Figure 1, method includes the following steps:
Step S100, lottery ticket buyer encrypt the lottery ticket of purchase using the public key in public and private key in plain text, obtain the
One lottery ticket ciphertext.
In the present embodiment, each lottery ticket buyer generates a pair of public and private key, and lottery ticket buyer buys coloured silk at any time
Ticket uses this pair of public and private key, generates public and private key without being repeated as many times.
Lottery ticket is not encrypted lottery ticket number or lottery ticket character etc. in plain text, can know particular content by vision, obtain
Know concrete meaning, for lottery ticket buyer when buying lottery ticket, institute is it is seen that lottery ticket plaintext.
By taking lottery ticket is lottery ticket number in plain text as an example, lottery ticket buyer A can choose 6 number combinations at random among 1-10
Sequence is arranged, and generates lottery ticket in plain text, for example, the lottery ticket of lottery ticket buyer purchase is in plain text 1,7,6,3,5,2, then lottery ticket
Buyer A is using the public key in its public and private key to the lottery ticket plaintext of purchase: 1,7,6,3,5,2 encrypting, obtain the first lottery ticket
Ciphertext, wherein the first lottery ticket ciphertext is the text not directly understood.
The lottery ticket that lottery ticket buyer buys is encrypted in plain text using the public key in public and private key, so that lottery ticket buyer institute
The lottery ticket of purchase is invisible in plain text, and in addition to lottery ticket buyer, other people are can not to know that lottery ticket is bright according to corresponding lottery ticket ciphertext
Text, so as to guarantee the fairness of welfare lottery ticket center prize.
Step S101, lottery ticket buyer send the lottery ticket purchase request for carrying the first lottery ticket ciphertext to welfare lottery ticket center.
Lottery ticket buyer buys lottery ticket by lottery purchase system, while sending to welfare lottery ticket center and carrying the first lottery ticket
The lottery ticket purchase request of ciphertext.
Step S102, welfare lottery ticket center obtain the lottery ticket purchase request for carrying the first lottery ticket ciphertext.
Step S103, welfare lottery ticket center call default intelligent contract to store the first lottery ticket ciphertext according to lottery ticket purchase request
Into block chain.
After welfare lottery ticket center receives the lottery ticket purchase request for carrying the first lottery ticket ciphertext of lottery ticket buyer transmission, according to
Lottery ticket purchase request calls default intelligent contract, is stored the first lottery ticket ciphertext into block chain using default intelligent contract, and
Transaction Hash is returned into lottery ticket buyer, lottery ticket buyer can utilize transaction Hash by tools such as block chain browsers
The case where checking its lottery ticket ciphertext cochain, to confirm whether purchase lottery ticket succeeds.In practical applications, block packing is block chain
Come what is operated, it is to store the first lottery ticket ciphertext into block chain that default intelligent contract is called at welfare lottery ticket center, and block chain is according to area
Block is packaged demand and carries out block packing processing to the first lottery ticket ciphertext, and stores the block of packing, and the first lottery ticket ciphertext is deposited at this time
Storage just comes into force.
Wherein, presetting intelligent contract is the intelligent contract that welfare lottery ticket center is pre-created, and only welfare lottery ticket center possesses calling
Permission., can also be by way of the called side of verifying the first lottery ticket ciphertext of storage as a result, when carrying out prize, Lai Tisheng is converted
The safety of prize can determine this tune if determining that the called side of the first lottery ticket ciphertext of storage is not welfare lottery ticket center by verifying
Storing the first lottery ticket ciphertext with default intelligent contract is not that welfare lottery ticket center is done, and the first lottery ticket ciphertext stored is invalid
, so as to avoid the default intelligent contract of hacker attack, stored on block chain it is some its do not know whether to get the winning number in a bond yet the
One lottery ticket ciphertext, influences prize.
It is to store the first lottery ticket ciphertext into block chain in the present embodiment, welfare lottery ticket center is not aware that lottery ticket buyer
What the lottery ticket of stake is in plain text, therefore, lottery ticket can not be just counted by way of big data in plain text, to ensure that prize knot
The fairness of fruit guarantees in addition, realizing data on chain can not distort by storing the first lottery ticket ciphertext into block chain
The authenticity of data prevents lottery ticket buyer from denying.
Step S104, for lottery ticket buyer after determining lottery, the center Xiang Fucai provides public key.
Welfare lottery ticket center is announced the winners in a lottery according to lottery ticket regulation, when announcing the winners in a lottery using traditional mode of announcing the winners in a lottery, determines this prize-winning
Announce the winners in a lottery lottery ticket in plain text, lottery ticket of announcing the winners in a lottery in plain text can be by publicity, and each lottery ticket buyer can be by checking the lottery ticket of announcing the winners in a lottery of publicity
Determine whether oneself gets the winning number in a bond in plain text, if lottery ticket buyer determines oneself lottery, can be after determining lottery, Xiang Fu
Color center provides the public key of oneself.
Step S105, welfare lottery ticket center obtain the public key that provides after winners' announcement in lottery of lottery ticket buyer, and using public key, announce the winners in a lottery
Lottery ticket is in plain text and the first lottery ticket ciphertext carries out prize-winning veritification.
Welfare lottery ticket center obtains the public key that lottery ticket buyer provides after winners' announcement in lottery, and then, welfare lottery ticket center is purchased using lottery ticket
Public key that buyer provides, lottery of announcing the winners in a lottery ticket are in plain text and the first lottery ticket ciphertext verifies whether lottery ticket buyer gets the winning number in a bond, and get the winning number in a bond
It veritifies.
In the present embodiment, welfare lottery ticket center specifically can verify whether lottery ticket buyer gets the winning number in a bond using following methods:
Lottery ticket of announcing the winners in a lottery is encrypted in plain text using public key, obtains the second lottery ticket ciphertext；Judge whether store in block chain
There is the first lottery ticket ciphertext to match with the second lottery ticket ciphertext；If in block chain it is not stored have match with the second lottery ticket ciphertext
First lottery ticket ciphertext, it is determined that get the winning number in a bond and veritify failure；If being stored with the first coloured silk to match with the second lottery ticket ciphertext in block chain
Ticket ciphertext then encrypts the first random data using public key, and encrypted result is returned to lottery ticket buyer, for lottery ticket
Buyer is decrypted using the private key pair encryption result in public and private key；Lottery ticket buyer is obtained using the private key pair in public and private key
The second random data that encrypted result returns after being decrypted；Judge whether the first random data is identical as the second random data,
It is veritified if so, determining by getting the winning number in a bond.
Specifically, the public key that welfare lottery ticket center is provided using lottery ticket buyer encrypts lottery ticket of announcing the winners in a lottery in plain text, obtains the
Two lottery ticket ciphertexts, later, welfare lottery ticket center need to verify whether the second lottery ticket ciphertext is stored on block chain, for example, judging block
Whether the first lottery ticket ciphertext that with second lottery ticket ciphertext matches is stored in chain, if not stored in block chain have and the second lottery ticket
The first lottery ticket ciphertext that ciphertext matches, it is determined that get the winning number in a bond and veritify failure, it is possible thereby to determine lottery ticket buyer there is no in
Prize, lottery ticket buyer deceive prize behavior, can give the certain punishment of lottery ticket buyer；
If being stored with the first lottery ticket ciphertext to match with the second lottery ticket ciphertext in block chain, continue to execute in next step
Suddenly, to the first random data, (wherein, the first random data can be raw using random number the public key provided using lottery ticket buyer
Generated at algorithm, the first random data here is only known at welfare lottery ticket center, and not to public) it is encrypted, and will add
Close result returns to lottery ticket buyer, and lottery ticket buyer utilizes public and private key after the encrypted result for receiving the return of welfare lottery ticket center
In private key pair encryption result be decrypted, obtain the second random data, the second random number that lottery ticket buyer obtains decryption
According to being sent to welfare lottery ticket center, welfare lottery ticket center is obtained after lottery ticket buyer is decrypted using the private key pair encryption result in public and private key
The second random data returned；Judge whether the first random data is identical as the second random data, if the first random data and
Two random data are identical, it is determined that are veritified by getting the winning number in a bond, it is possible thereby to determine that lottery ticket buyer gets the winning number in a bond, can give the lottery ticket
Buyer rewards accordingly；If the first random data and the second random data be not identical, it is determined that get the winning number in a bond and veritify failure, thus may be used
To determine lottery ticket buyer there is no getting the winning number in a bond, lottery ticket buyer deceives prize behavior, it is certain can to give lottery ticket buyer
Punishment.
It is illustrated below with reference to example, the public key of lottery ticket buyer A is P, and public key P is sent to good fortune by lottery ticket buyer A
Color center, this lottery ticket of announcing the winners in a lottery is in plain text 1,7,6,3,5,2, and welfare lottery ticket center is using public key P to announcing the winners in a lottery lottery ticket in plain text: 1,7,6,3,
5, it 2 being encrypted, obtains the second lottery ticket ciphertext C, welfare lottery ticket center will verify whether the second lottery ticket ciphertext C is stored on block chain,
Specifically, block chain is inquired according to the second lottery ticket ciphertext C, determines whether be stored on block chain and the second lottery ticket ciphertext C phase
The the first lottery ticket ciphertext matched, if it does not exist, it is determined that get the winning number in a bond and veritify failure, and if it exists, then perform the next step rapid, welfare lottery ticket center benefit
The first random data Rand (secrecy underground) is encrypted with public key P, obtains encrypted result Cnew, and by encrypted result
Cnew returns to lottery ticket buyer, and lottery ticket buyer is decrypted Cnew to obtain the second random data using the private key of oneself
RandNew, and the second random data RandNew is sent to welfare lottery ticket center, welfare lottery ticket center compare Rand and RandNew whether one
It causes, if unanimously, it is determined that veritified by getting the winning number in a bond；If inconsistent, it is determined that get the winning number in a bond and veritify failure.
The method whether above-mentioned verifying lottery ticket buyer gets the winning number in a bond provides the private of oneself to welfare lottery ticket center without lottery ticket buyer
Key, that is, oneself provable prize-winning, without generating public and private key, the lottery ticket that a lottery ticket buyer buys at any time every time
It binds with this pair of public and private key of lottery ticket buyer, without the more public and private keys of set of lottery ticket buyer keeping, avoids public and private in plain text
The defect that key is obscured.
In a kind of optional embodiment of the present invention, it is likely that occur announcing the winners in a lottery there are multiple groups lottery ticket plaintext the case where, when going out
Now in this case, using lottery ticket buyer provide public key respectively to multiple groups announce the winners in a lottery lottery ticket in plain text encrypt, obtain multiple groups
Second lottery ticket ciphertext matches the first lottery ticket ciphertext with multiple groups the second lottery ticket ciphertext respectively；First lottery ticket ciphertext if it exists
It is matched with any one group of the second lottery ticket ciphertext in multiple groups the second lottery ticket ciphertext, it is determined that veritified by getting the winning number in a bond, it is possible thereby to really
Fixed lottery ticket buyer gets the winning number in a bond, and can give lottery ticket buyer and reward accordingly；First lottery ticket ciphertext and multiple groups the if it exists
Two lottery ticket ciphertexts mismatch, it is determined that and it gets the winning number in a bond and veritifies failure, it is possible thereby to determine that lottery ticket buyer does not get the winning number in a bond, the coloured silk
Ticket buyer deceives prize behavior, can give the certain punishment of lottery ticket buyer.
In addition, if lottery ticket buyer determines the group that oneself is got the winning number in a bond prize-winning group can be provided to welfare lottery ticket center, in welfare lottery ticket
The heart can be determined according to prize-winning group announces the winners in a lottery lottery ticket in plain text accordingly, prize-winning veritification is carried out, to improve veritification efficiency.
