The personnel actually involved in the number shaking method include number shaking host application personnel 301 who initiate or organize number shaking activities, business operator 302 who maintains the operation number shaking platform 201, and number shaking activity related party 303, wherein information is transferred and exchanged through the network.
The third-party random seed generation platform 203 in this embodiment may be, for example, a lottery drawing platform in china, and the random seed generated by the third-party random seed generation platform 203 may be, for example, a lottery drawing number generated by the lottery drawing platform. Accordingly, number shaking platform 201 may generate further number shaking results based on the random seed number shaking operation.
In this embodiment, for example, the service operator 302 may issue, in the serial number platform 201, the serial number shaking application methods in various application scenarios and the random seed information of the random seed associated with the serial number shaking application methods. Wherein the random seed information may be, for example, lottery drawing numbers generated by the chinese welfare lottery two-color ball drawing platform in the future (the future refers to the time when the lottery drawing activity is issued).
For example, the service operator 302 may implement the functions of adding, deleting, issuing, and offline of the number shaking application method and the functions of adding and issuing the random seed information through the number shaking platform 201. Specifically, the service operator 302 may operate the number shaking platform 201 to add a number shaking application method through a browser webpage interaction mode, including adding the following information related to the number shaking application method: the number of the number shaking application method, the name of the number shaking application method, the application scene description of the number shaking application method, the number shaking result interaction method and the like.

We calculate the summary character string 9b843183f60e9c066d43675dd67a891d321c429e51c52b25792bad4fb5f279ed by using the SM3 summary algorithm to the T11.txt, and calculate the summary character string 6fff88435d1281c85c4f83a3f01ae66511eae6cf88c559d 48196594b9364ac to the T21. txt.
Then the forensic development kit using a hundred degree hyperlink (https:// xupper. ***.com /) at 18/8/2021 (the day before random seed generation) of the shaking platform 201 stores 9B843183f60e9c066d43675dd67a891d321c429e51c52B25792bad4fb5f279ed and 6fff88435d1281c85c4f83a3f01ae66511eae6cf88c559d1B48196594B9364ac onto the block chain respectively, while obtaining a warranty ID B69a61acd2ee05a1e86c616d 4350d4ba9a42dfe0cf2701bf1c47 fbdace 0d and 02af 2 c 583 d4350d4ba9a42dfe0c 47B 31B and a 3B 53B 3B and receiving corresponding summary data record of the summary database record of the summary record string 468B 466B 39B and the summary database record ID NO 8B 48B 8B (the summary record B463B) for generating the summary database record of the summary record ID B463B 8B 468B 303 and the summary record B3878B 3B.
Then, the shake platform 201 sends the electronic file of t11.txt, the digest character string 9B843183f60e9c066d43675dd67a891d321c429e51 e 52 c 25792bad4fb5f279ed, the deposit security ID B69a61acd2ee05a1e86c616d 4350d4ba9a42dfe0cf2701bf1c47bcdafb 0d to the relevant person participating in the house draft shake number through the internet at 18 th 8 th 18 th (the day before the random seed generation) in 2021, and sends the electronic file of t 21.865txt, the digest character string 6fff88435d1281c85c4f83a3f01ae66511eae6cf88c559d1B48196594B93 ac, the deposit security text B829 2B 128f 85 f83a3f 3a 66511 aee 6c 559d1B 38735, the deposit security text B368B and the corresponding shake information of the corresponding to the application of the twin shake book of the document No. 3625B 368B and the random seed generation (the corresponding shake No. 368). At this time, the number shaking platform 201 shall pair the documents of "T12. txt" and "T22. txt" to the relevant persons participating in the number shaking activity. Thus, the third party random seed generator cannot control the lottery outcome by controlling the number of prizes won by the welfare lottery at 8/19/2021094/2021 because the third party random seed generator cannot know the order of actual participation in the lottery list (corresponding to claim L3).
Then number shaking platform 201 in 2021 8 month 19 evening 22: 00 obtains the current day lottery number 25113309282415 as the third party random seed from the official website of the Chinese welfare lottery through the web crawler program. Then the number shaking platform 201 calculates the number shaking result according to the algorithm information in the t11. txt': taking a decimal arrangement serial number 9412039519 corresponding to lottery numbers from a third-party random seed arrangement combination sorting file corresponding to the summary character string a585b7d49c69b2bf0eaf0004f6170879 (the serial numbers are used for arranging all possible lottery combination arrangements in descending order of decimal and numbering from serial number 1), then extracting 1000 integers from 9412039520 lines in a random number set corresponding to the summary character string 0cad8e6ccaa186061e57ede1d3900f27 in T11. txt), then respectively extracting the integers from 4700 to obtain a remainder List List < M >, then sequentially extracting each number from the List < M > List (assigning a numerical value to L) to carry out the following operation, extracting the number List from the L +1 line in the rocking List of T12.txt, if the L +1 line is searched, continuing to extract the next line, and if the L +1 line is not found, continuing to extract the number List from the rocking List of the first line which is not found, until finding the rolling List F which is not extracted, setting the rolling List to be in an extracted state and putting the rolling List into a rolling List List < F >, then taking 1000 rolling lists in the rolling List List < F > as the signing List of the current house property billing rolling (because of patent space limitation, a detailed calculation rolling result process is not listed here), and finally sending the rolling result and the T12. txt' to related personnel participating in the house property open tray sales rolling activity (after the third party random seed which is depended on the rolling task in the corresponding claim is generated, the rolling platform generates the rolling result according to the rolling task data information W1 and W2 and sends the rolling result and the W2 to the application equipment of the related party of the rolling activity, corresponding to the step S305 in the attached figure 3 of the specification). The number shaking platform 201 calculates the number shaking result according to the algorithm information in the t21. txt': taking a decimal arrangement serial number 9412039519 (which is the serial number of all possible lottery combination arrangements of the lottery arranged from small to large in decimal order and numbering from serial number 1) from a third-party random seed arrangement combination sorting file corresponding to the summary character string a585b7d49c69b2bf0eaf0004f6170879, then respectively taking 50 integers from 9412039520 lines in a random number set corresponding to the summary character string 0cad8e6ccaa186061e57ede1d3900f27 in T21.txt, then respectively taking the integers from 700 to obtain a remainder List List < M >, then sequentially taking each number from the List < M > List (assigning a numerical value to L) to carry out the following operation, extracting the List from the L +1 line in the rocking List of T22.txt, if the List L +1 line is searched for the next line, continuing to extract the List from the rocking List of the number of the first line if the List of the last line is not searched, continuing to extract the List of the number from the last line of the List of the third-party random seed arrangement sorting file, until finding the shaking List F which is not extracted, setting the shaking List to be in an extracted state and putting the shaking List into the shaking List List < F >, then 50 shaking lists in the shaking List List < F > are used as the result List of the double random one-public shaking (because of the patent space limitation, the detailed procedure for calculating the shaking result is not listed here), and then sending the number shaking result to a law enforcement officer in the double random one-public activity for law enforcement, and after the law enforcement is finished, sending t22.txt to a related officer participating in the double random one-public number shaking activity (after a third party random seed depending on the number shaking task is generated in the claims, the number shaking platform generates a number shaking result according to number shaking task data information W1 and W2, and sends the number shaking result and W2 to an application device of a related party of the number shaking activity, corresponding to step S305 in fig. 3 of the specification). For the double random one-publication activity, because the 'T22. txt' publication is performed after the law enforcement activity is finished, the law enforcement and casual inspection personnel still cannot know whether the personnel is evacuated after the third party random seed publication, and the confidentiality function of the number shaking result is realized.
In conclusion, the number shaking method provided by the invention has the following effects:
1. the method and the process for storing the verification shaking number in the block chain are disclosed and cannot be tampered, so that the shaking number result is generated, and the problem of low reliability of the shaking number result due to the fact that the shaking number method and the process are not disclosed, easy to tamper, unprofessional and difficult to verify is solved.
2. The number shaking platform 201 and the third-party random seed module for generating the random seeds in the embodiment of the invention are independent of personnel in a number shaking application scene, so that the interest relevance is greatly reduced, and the problem of subjective distrust of a number shaking result by a number shaking activity relevant party 303 is reduced.
3. In the invention, the summary character strings of the number shaking task data are stored and certified in the preset block chain system 202, and the third-party random seed arrangement combination sequencing number file and the random number set file are used, so that the number shaking result generation algorithm principle can be easily understood by personnel and related personnel participating in number shaking in a number shaking application scene, the number shaking result can be automatically and quickly calculated, and the calculated number shaking result and the result generated by the number shaking platform 201 are certified, so that the number shaking result generated by the number shaking application platform is high in reliability.
4. In the invention, only a small amount of data of the data summary character string of the number shaking task is stored and verified to a preset block chain system, and other large amount of data storage and operation are realized in the traditional centralized computing architecture. The method avoids the problems of high cost, low speed and difficult supervision and verification caused by storing and operating all shake number related data and calculation through a block chain system like block chain distributed contract application, and thus the method has more economic practicability.
5. By reordering and encrypting the list actually participating in the calculation of the number shaking algorithm, the randomness of the number shaking result is enhanced (the number of possibility of permutation and combination of the number shaking result is increased). If the calculation is carried out only according to the disclosed list sequence and the disclosed random number set, the number of permutation combinations of the number shaking result cannot exceed the number of permutation combinations of the third-party random seed due to the limitation of the number of random numbers in the random number set. The number of the arranged combinations of the two-color balls of the chinese welfare lottery ticket in the above embodiment is 12759183360. If the list of rocker numbers is not randomly ordered and encrypted, the permutation and combination probability of the rocker result (relative to the fixed list of participating rocker numbers in W1) cannot exceed 12759183360. The invention randomly orders and encrypts the list of the shaking numbers in W2, thereby greatly increasing the number of permutation and combination (exceeding 12759183360) of the final shaking number result (relative to the fixed list of the participating shaking numbers in W1).
6. By encrypting part of data of the number shaking task data and disclosing the encrypted data after the third-party random seeds are generated, the invention enhances the security of the number shaking activity, so that third-party random seed generation personnel can not control the number shaking result by controlling the random seeds.
7. By encrypting part of data (W2 in the claims) of the number shaking task data and disclosing the encrypted part of data at intervals after the third-party random seeds are generated, the invention realizes that after the third-party random seeds are disclosed, personnel participating in number shaking can not calculate the number shaking result by themselves due to lack of part of data, thereby realizing the confidentiality of the number shaking result.
