For a better understanding of the technical solution of the present invention, the following is further described with reference to examples.
The demand conditions are as follows:
when a scientific and technological company carries out the first public share-collecting on a chain, and carries out the public share-collecting through a legal on-chain transaction platform, the supervision of a supervision department and the supervision of all investors are required, so that the current key information such as technology, finance, personnel and the like of the scientific and technological company is required to be disclosed, the modification of the key information due to the personal benefit of related people is avoided, the falsification of the key information is avoided, and the share-collecting is carried out.
However, considering that the information of the company needs to be kept secret before the stock is overtly collected, so that the information is prevented from being revealed, risks of malicious business competition or infringement of technical patent rights are caused, and since the company performs stock collection related operations on a chain, a supervision department performs strict supervision and check on all relevant information of the company, and also considers the special property of the company, provides due secret measures for the company before the check is completed, and ensures consistency of the information of the company before and after the check is completed.
The specific steps are as follows:
(1) building (under chain) of public data information base
Firstly, establishing all information required to be disclosed by the company, packaging the information after all confirmation works are completed, outputting an information base of the disclosure data, namely 'disclosure data', wherein the information in the information base is the final edition information which is checked by the supervision department. The company needs to be responsible for the information, and the uploading information is not consistent with the actual information, has false components and is subjected to legal level sanctions.
(2) Introducing a unidirectional mirror module, and encrypting data (under chain) by the unidirectional mirror module
The disclosure data is imported into the one-way mirror module, and the one-way mirror module encrypts the disclosure data by an asymmetric special algorithm. Assuming that the "disclosure data" is "abcdefghijklmnopqrvuvwszabcdefghirphrsnonotuvwxyz 01234556789", after encryption by an asymmetric special algorithm, it is "U2FsdGVkX1e kx 5B1j9ROTFCQxk1 cjgidfqakaabaap 077us52", then the result after encryption is decimal to "3254234336566571717054418572729305526432297529967388580183609153654126798620322286560352", and a series of private keys for decoding are generated, the private keys are randomly composed of case english letters plus 0-9 digits, and it is assumed to be abcdefgABCDEFG1234567 (the private keys may be set to a unique fixed state, or a random state that dynamically changes every minute, which form is used, the private keys may be confirmed and set at this time, but once generated, the form may not be switched any more).
(3) After the encryption of the unidirectional mirror module is completed, the unidirectional mirror module is arranged and combined (under the chain)
The one-way mirror module determines that the decimal result bit number is 88 according to the data, divides the number by 10 to obtain 8 groups of required group numbers, and the number of groups is +1 and 9 groups because of the remainder of 8;
then three to eight english capital letters are randomly generated per group as serial numbers representing the sequence, such as the sequence XXS/OUI/RTU/DFG/YJH/DWY/BNM/CUF/GDL, and the sequence data is recorded in a one-way mirror module, the decimal result "3254234336566571717054418572729305526432297529967388580183609153654126798620322286560352" is divided into groups every 10 digits from left to right, and the final result is XXS3254234336/OUI5665717170/RTU5441857272/DFG9305526432/YJH2975299673/DWY8858018360/BNM9153654126/CUF7986203222/GDL86560352, and the final full encryption result is recorded.
(4) After the arrangement and combination of the unidirectional mirror modules are completed, the upper and lower links of the chain are connected (under and on the chain)
The unidirectional mirror module binds and associates the disclosure address with the information to be disclosed, and places the disclosure address into a correlation center to form a state that the disclosure information, the unidirectional mirror module and the disclosure address are mutually connected, and automatically triggers the corresponding connection of the disclosure information and the disclosure address.
(5) The chain disclosure address information is guided by the contract encryption module to generate appointed quantity and establish a pass (chain)
And generating a corresponding pass (Token) in the revealed address on the chain according to the final complete encryption result provided by the unidirectional mirror module, wherein the pass (Token) name is that each group randomly generates three English capital letters, and the upper limit of the pass (Token) is infinitely increased. The first generation amount depends on the final full encryption result.
If the address is first disclosed on the chain as a final full encryption result, the following generation should be:
name of general certificate: XXS corresponds to the number of passes: 3254234336
Name of general certificate: OUI corresponds to the number of passes: 5665717170
Name of general certificate: RTU corresponds to the number of passes: 5441857272
Name of general certificate: DFG corresponds to the number of passes: 9305526432
Name of general certificate: YJH corresponds to the number of passes: 2975299673
Name of general certificate: DWY corresponds to the number of passes: 8858018360
Name of general certificate: BNM corresponds to the number of passes: 9153654126
Name of general certificate: CUF corresponds to the number of passes: 7986203222
Name of general certificate: GDL corresponds to the number of passes: 86560352
Because the pass has the capability of random casting and increasing the distribution, when the future disclosure information changes, the one-way mirror module can randomly increase or decrease the pass number (increase continuously generates the corresponding pass and decrease the corresponding pass is driven into a black hole, and the black hole address refers to a special address in the blockchain, once any pass is put into the address, the address can be permanently removed from circulation in the blockchain, and is synonymous with destruction) so as to correspond to the latest encryption result, and the logic changed when the one-way mirror module receives an instruction to update the information on the disclosure address.
In addition, the disclosed address is limited by the contract encryption module of the unidirectional mirror module, the pass card can not be forwarded to any non-black hole address, and the pass card can be automatically transferred to the black hole when a new pass card is accessed from the outside. And if the one-way mirror module generates a new encryption result along with the change of the disclosure information, the contract encryption module discovers that the packet needs to be additionally increased or decreased when the pass is updated, and the contract encryption module can newly increase or decrease the packet according to the step (3).
(6) Complete the generation of the pass, and check the generated result (on-chain & off-chain)
When the verification result is generated, the address pair is disclosed to generate the verification names and the verification quantity after the completion of the generation, a callback is sent to a contract encryption module provided by the unidirectional mirror module, the contract encryption module verifies the on-chain result after receiving the corresponding callback, if the result is correct, the update is successful, and the successful result is displayed for operators and external non-core personnel; if the output result is incorrect, the result represents that the updating fails, the monitoring personnel is informed immediately when the result is displayed for the operator and the external non-core personnel, and after the monitoring personnel checks the result, the one-way mirror module can be reset, and the process is started from the step (2) again.
(7) Fixed or random checking at time intervals to prevent endless tampering of the information under the chain (on-chain & off-chain)
When the output result is "correct", it means that the directional disclosure encryption on the chain of the unidirectional mirror module is completed, the next time is counted from the completion, the next verification is performed by the contract encryption module, the random time is set every 1-86,400 seconds (the time can be set to be a fixed time, the time is set before the encryption is started), the verification content is whether the three are consistent, namely the disclosure information (data in the disclosure database), the unidirectional mirror (final full encryption result after encryption), the disclosure address (on-chain pass name and corresponding pass number) is consistent, if the verification result is consistent, the disclosure of the result is correct to the external owner, other information is not disclosed, then the next verification is continued to be performed, if any party of the verification result is wrong, the process is processed according to the update failure result in the step (6), and the verification process is terminated. If the account is an asset account, external artificial intelligence expansion can be used, operation authorities such as corresponding transactions are frozen, and information is sent to a preset supervisor side for warning.
(8) The supervisor decodes the disclosure address information (in-chain) by the private key
When a supervisor needs to acquire real disclosure information content through a disclosure address, only a secret key abcdefgABCDEFG1234567 needs to be input into a contract encryption module corresponding to a unidirectional mirror module, the unidirectional mirror module can decrypt information in the disclosure address through the setting of the contract encryption module, the decryption result is induced through an asymmetric special algorithm, and finally the corresponding readable disclosure information content is output.
In this embodiment, the specific logic (in-chain & out-of-chain) when the disclosure information needs to be modified is:
when the disclosure address has been generated and the disclosure address has been set by the contract encryption module, and when the disclosure address is verified once (in step (7)) at random time intervals of 1-86,400 seconds, if information needs to be changed, the changed and changed requirement information needs to be transmitted to the one-way mirror module manually (note that here, the changed information needs to be transmitted to the one-way mirror module, the changed behavior needs to be transmitted to the one-way mirror module, that is, the one-way mirror module receives the disclosure information, the fact that the disclosure information is about to change is about to happen), when the one-way mirror module receives the instruction, the one-way mirror module performs online verification at random at a frequency of once every 1-15 seconds, at this time, the verification object is "disclosure information (data in disclosure data base) — (final full encryption result after encryption)", the verification and the "disclosure information (data in disclosure data base) — one-way mirror (final full encryption result after encryption) at step" at the time of the first (step) need not to conflict with each other, and the three verification fail to be verified by any party immediately.
At this time, the operator can exchange the disclosure database and re-upload it until the one-way mirror module confirms that the new disclosure database is packaged and uploaded, and then encrypts the new data. After the unidirectional mirror module encrypts the information through an asymmetric special algorithm, the information is continuously grouped according to the flow of a corresponding contract encryption module, a finally generated encryption result is grouped on a chain disclosure address, a corresponding pass is generated according to a serial number and a new field, after all the information is completed, the disclosure address is sent to a contract encryption module callback, the contract encryption module verifies after receiving the information, if the output result is correct, the information updating is successful, and the result is displayed outwards; if the output result is incorrect, the update fails, the supervisor is notified while the result is displayed externally, and after the supervisor checks the result, the supervisor waits for the instruction to repeat the step until the output result is correct.
From the above, the information disclosure directed by the science and technology company is directed when the first overt share-up is performed on the chain.
It can be found that in the present application, the decentralization characteristic of the entire blockchain is not destroyed, the disclosure address information on the chain is changed in an environment which accords with decentralization fairness, credibility and transparency, all changes are made to be circulated, and when abnormal changes occur, the quick response and notification of the entire blockchain can be realized;
moreover, the method and the device ensure that only specific crowd with private keys can carry out directional information disclosure, and non-specific crowd can not provide back detailed information, but ensure that the integrity and the authenticity of the disclosure information are confirmed, and the confirmation result is disclosed;
through the method and the device, more operation space can be provided for the supervision of data on a blockchain chain and the information supervision of the uplink in the future.
In addition, for better understanding, based on the embodiments of the present application, a specific implementation application scenario is further provided:
application scenario (1): revealing in-chain sensitive information to specific regulatory populations and in-chain information privacy to non-specific populations
According to the upper-level requirements, after 20XX years, a certain public institution needs to upload own revenue information to an industry block chain of national supervision construction in a fixed time per month for supervision by a supervision department and supervision by people, but other countries can calculate various resident life information of China according to the data of the public institution in consideration of the special nature of the institution, if uploading detailed data on the block chain, a large amount of information can cause unnecessary trouble, but if the design of the industry block chain is directly modified only because of the special nature of the institution, the property of decentric of the block chain is violated, so that the public and trusted property is greatly reduced, and the disclosed revenue data cannot be convinced. Therefore, the current public institution urgently searches for a device which can enable an upper supervision department to check the detailed revenue data information at any time, enable people to know that the data information is checked by the upper supervision department, avoid private tampering before and after checking, and ensure that people only know the information and cannot know the revenue detailed data information so as to prevent unnecessary trouble of information leakage.
The solution is as follows:
binding the under-chain nutritive information with the on-chain public address through the one-way mirror module, generating the encrypted information corresponding to the nutritive information data by using a special encryption algorithm of the one-way mirror module on the on-chain public address, and generating a corresponding private key. When the upper supervision department holds the private key, the information of the public address on the chain can be consulted by reversely decoding the private key through the unidirectional mirror module again, and the real information of the nutrient and receipts can be obtained by decoding the information of the public address on the chain because the public address and the information of the information under the chain are in a binding relation.
Meanwhile, the unidirectional mirror module can conduct random time verification on the under-chain nutritive information and the information of the on-chain public address, and when the fact that the under-chain nutritive information is not matched once the verification is found, the fact that the under-chain nutritive information has the change of unknown reasons is explained, supervision personnel with private keys can be synchronized immediately, and possible risks are prevented.
In addition, for people, the unidirectional mirror module synchronously updates the comparison result of random time verification to the revealed address on the chain for other people without the private key to review, and at the moment, people without the private key can see whether the comparison result is correct or not, but cannot see the detailed information of the revealed address.
The method is formed by a special encryption algorithm and new product logic on the original product logic of the blockchain, and under the condition that the function of the blockchain product is not modified, the characteristics of the decentralization of the blockchain are reserved, and the requirements of directional disclosure and information security are met.
Application scenario (2): timing and fixed point presentation of secret information
The talents in China select examination contents, which are ordered by education institutions, and the contents are stored in a sealed manner after the examination is performed, and the examination is performed by issuing and unsealing before the examination is performed. However, with the continuous development of future electronic technology, online examination will occupy a place in future examination rooms, but online electronic examination is stored from propositions to information preservation and then to steps of issuing and unpacking, which may be subject to technical risks such as network attack, data loss and damage in the network transmission process, and in the process, opportunities for too many non-core personnel or illegal personnel to touch or tamper with data in an improper manner are easily generated, so that the risk of data leakage is caused.
The solution is as follows:
the problem is solved by not only hopefully uploading test question data to a network without losing the test question data, but also having strong attack resistance, ensuring that as few people as possible touch the core test questions, and avoiding the possibility of tampering, so that the test questions can be uploaded to a public blockchain which is regulated or approved by the country, and the unidirectional mirror module is combined, so that the data of the blockchain is prevented from being lost or damaged by the decentralization characteristic of the blockchain, the data of the blockchain can be combined and read only through a private key generated by the unidirectional mirror module, and any action of tampering the original data can lead to decryption failure of the private key due to the arrangement of the unidirectional mirror module, thereby being perceived by a supervisor, and being capable of furthest preventing internal personnel or illegal personnel from touching or tampering the data in an illegal way. And the unidirectional mirror module also supports timing disclosure, and can automatically restore data through a private key according to agreed disclosure data time and synchronize to a designated node on the chain or a related address under the chain.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
