Summary of The Invention

The inventor finds that, in the related art, after application software is developed, a specific population is generally faced, and the specific population may be a population for testing the application software or a population for purchasing the application software, and certainly, the specific population is not limited thereto. In order to realize the application software used by a specific crowd, the activation code is generally issued to the specific crowd, but the application scenario of the activation code is not limited to this. In the related art, the activation codes are generally centrally and uniformly managed and issued by a product manager, the total number of the activation codes and the verification rules of the activation codes are determined by the manager, and the manager can modify the rules at will. However, if the user reveals the activation code, it is easily abused by others, such as the user's activation code of the office software, which, once published, is used by the person to activate the office of others. Meanwhile, the user activation data cannot be known, and the activation activity of the software cannot be evaluated. The management party can modify the total number of the activation codes and the verification rule at will, and for a user, the problem that the information of the user to the activation code rule is opaque and asymmetric exists; for products, the products cannot provide a fair, fair and transparent activation management environment.

Based on the above analysis, the inventor conceived a way to generate a target activation code based on an activation code generation request through a blockchain platform, and an activation code management center sent the target activation code to a client, so that the activation code can be managed in a decentralized manner, and any third party cannot change the activation code rules and the total number at will. The activation code rule is publicly transparent to the user; for products, a fair, fair and transparent activation management environment can be provided, so that the possibility that a manager randomly modifies the total number of activation codes and the verification rule is remarkably reduced, and better experience is brought to users.

By disclosing one or more targeted activation codes and/or attribute information for one or more targeted activation codes, it is possible to make all activation codes publicly transparent, so that the number of times a product is activated is publicly transparent.

Having described the general principles of the invention, various non-limiting embodiments of the invention are described in detail below.

Application scene overview

First, an application scenario of the activation code management system according to an embodiment of the present invention is described in detail with reference to fig. 1.

FIG. 1 schematically shows a diagram of activation code management system interaction with a client, according to an embodiment of the invention.

As shown in FIG. 1, the activatecode management system 100 includes an activatecode management center 101 and ablockchain platform 102.

The activationcode management center 101 is configured to: acquiring a user block chain address sent by a client 103; sending an activation code generation request carrying a user block chain address to theblock chain platform 102; the target activation code is sent to the client 103.

Theblockchain platform 102 is configured to: acquiring an activation code generation request carrying a user block chain address; and generating a target activation code in response to the activation code generation request, and sending the target activation code to the activationcode management center 101, wherein the intelligent contract is pre-deployed in theblockchain platform 102, and the intelligent contract at least comprises the activation code generation contract.

According to the embodiment of the invention, the user can acquire the activation code qualification by purchasing or activity picking and the like to obtain the user block chain address, and the user can provide the own user block chain address to the activationcode management center 101 through the client 103. Then, the activationcode management center 101 sends an activation code generation request carrying the user blockchain address to theblockchain platform 102, that is, sends a transaction request for obtaining the activation code to theblockchain platform 102.

After acquiring an activation code generation request carrying a user blockchain address, theblockchain platform 102 generates a target activation code by executing a pre-deployed activation code generation contract, then sends the target activation code to the activationcode management center 101, and finally sends the target activation code to the client 103 by the activationcode management center 101.

According to an embodiment of the invention, theblockchain platform 102 may also pre-deploy an activation code validation contract. Theblockchain platform 102 may further obtain an activation code verification request sent by the client 103 and signed by using a private key corresponding to the user blockchain address, and verify the user blockchain address according to an activation code verification contract in response to the activation code verification request.

According to an embodiment of the invention, the blockchain account may include a user private key and a user blockchain address. Wherein the private key is stored by the user. The user blockchain address can be deduced according to the private key, and the private key cannot be deduced according to the user blockchain address.

According to an embodiment of the present invention, a user may initiate a verification transaction directly to theblockchain platform 102 through the client 103, and certainly, the request needs to be verified by using a private key verification activation code. The private key of the user cannot be deduced by the signature verification parameter, but the user block chain address can be deduced, and meanwhile, the private key of other users cannot be used for deducing the user block chain address of a non-user.

After the user initiates the verification activation code, whether the user initiates the verification activation code for the owner of the private key can be verified, namely, the user block chain address used when the user initiates the verification activation code is the address derived from the private key. And the verification is successful only after the verification of the block chain addresses is consistent.

By the embodiment of the invention, the intelligent contract of the activation code is deployed on the block chain platform, so that the management cost for generating the activation code and verifying the activation code in a centralized management mode can be saved; meanwhile, the activation codes are removed from the center, the total number of the activation codes is determined, and the rule is determined; on the blockchain platform, all the activation codes are public, and the information is transparent.

According to the embodiment of the invention, the target activation code is generated based on the activation code generation request through the block chain platform, and the activation code management center sends the target activation code to the client, so that the activation code can be managed in a centralized manner, and any third party cannot change the rules and the total number of the activation code at will.

Exemplary method

In connection with the application scenario of fig. 1, an activation code management method according to an exemplary embodiment of the present invention is described below with reference to fig. 2. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.

FIG. 2 schematically shows a flow diagram of an activate code management method according to an embodiment of the invention.

The activation code management method according to the embodiment of the invention is applied to an activation code management center, and as shown in fig. 2, the method includes operations S210 to S230.

In operation S210, a user block chain address transmitted by a client is acquired.

According to the embodiment of the invention, the address rule of the user blockchain address needs to conform to the blockchain ether house address format and the like. Specifically, for example, the user block chain address may be in the following format: 0x4f935600dcb7c4c7de17d4611113e3a5b8a718 ea.

In operation S220, an activation code generation request carrying a user blockchain address is sent to the blockchain platform, so that the blockchain platform generates a target activation code based on the activation code generation request, where an intelligent contract is deployed in the blockchain platform in advance, and the intelligent contract at least includes an activation code generation contract.

According to the embodiment of the invention, after acquiring the user block chain address sent by the client, the activation code management center generates the activation code generation request based on the user block chain address, and then sends the activation code generation request to the block chain platform.

In operation S230, a target activation code is transmitted to the client.

According to the embodiment of the invention, the blockchain platform responds to the activation code generation request, generates the target activation code by executing the activation code generation contract, and the activation code management center can acquire the target activation code and send the target activation code to the client.

According to the embodiment of the invention, the activation code management center has a corresponding management center block chain account number, and sends an activation code generation request to the block chain platform based on the management center block chain account number.

According to the embodiment of the invention, the account number of the block chain in the management center is held by the manager of the activation code, so that the purpose of preventing other accounts from randomly initiating and generating the activation code is achieved. Since the activation code generation request is sent to the blockchain platform based on the externally exposed contract transaction interface, in order to prevent other account numbers from initiating and generating activation codes at will, the activation code generation request can be initiated by the management center blockchain account number.

According to the embodiment of the invention, the target activation code is generated based on the activation code generation request through the block chain platform, and the activation code management center sends the target activation code to the client, so that the activation code can be managed in a centralized manner, and any third party cannot change the rules and the total number of the activation code at will. The activation code rule is publicly transparent to the user; for products, a fair, fair and transparent activation management environment can be provided, so that the possibility that a manager randomly modifies the total number of activation codes and the verification rule is remarkably reduced, and better experience is brought to users.

FIG. 3 schematically shows a flow diagram of an activate code generation method according to an embodiment of the invention.

The activate code generation method according to the embodiment of the present invention is applied to a blockchain platform, and as shown in fig. 3, the activate code generation method includes operations S310 to S320.

In operation S310, an activation code generation request carrying a user block chain address is obtained, where the activation code generation request is sent by an activation code management center after the client sends the user block chain address to the activation code management center.

According to the embodiment of the invention, the activation code generation request carries the user block chain address, and the activation code verification rule can be called subsequently through the user block chain address. Meanwhile, the rule check can be carried out through the user block chain address. It should be noted that, according to the embodiment of the present invention, when the activation code verification is required, a private key held by a user may initiate a transaction for verifying the activation code, then a corresponding activation code verification rule is invoked through the user's own block chain address, and finally the verification is performed based on the invoked activation code verification rule.

The method shown in fig. 3 is further described with reference to fig. 4 and 5 in conjunction with specific embodiments.

FIG. 4 schematically shows a flow diagram of an activate code generation method according to another embodiment of the invention.

As shown in FIG. 4, the activate code generation method includes operations S410 to S420.

In operation S410, it is determined whether the user blockchain address qualifies for an activate code before responding to the activate code generation request.

In operation S420, in the event that it is determined that the user blockchain address qualifies for an activation code, a request is generated in response to the activation code.

According to the embodiment of the invention, whether the user blockchain address is qualified for acquiring the activation code can be determined through an intelligent contract which is pre-deployed in the blockchain platform. For example, the smart contract includes at least an activation code generation contract, which may verify rules such as whether a user blockchain address qualifies for and/or the number of activation codes that can be obtained, including accounts with non-administrator accounts and non-public private keys.

According to the embodiment of the invention, after the verification is successful, the target activation code can be generated in response to the activation code generation request. Meanwhile, the block chain link point can store all generated target activation codes and activation codes corresponding to the user block chain addresses into the block chain link point database. These results are recorded and can be used at least for verification the next time the activation code is retrieved.

In operation S320, a target activation code is generated in response to the activation code generation request, and the target activation code is sent to an activation code management center, wherein an intelligent contract is pre-deployed in the blockchain platform, and the intelligent contract at least comprises the activation code generation contract.

According to the embodiment of the invention, the intelligent contract of the activation code can be pre-deployed in the block chain platform, and the content of the pre-deployed intelligent contract is different according to different business targets. For example, the smart contract may include an activation code generation contract, an activation code validation contract, a derived activation code contract, and so forth.

According to the embodiment of the invention, when the intelligent contract of the activation code is deployed in the blockchain platform in advance, the total number of the activation code required to be set in the intelligent contract, the activation code generation rule contained in the activation code generation contract and the activation code verification rule contained in the activation code verification contract can be determined by a manager of the activation code management center.

In order to prevent the account of the manager of the non-activation code management center from acquiring the activation code at will, the activation code generation rule may specify the blockchain address of the manager of the activation code management center, so that the blockchain address of the manager can request to acquire the activation code, and the activation code management center may reserve the blockchain address of the intelligent contract after the intelligent contract is deployed.

According to an embodiment of the present invention, the format of the activation code may be a character string generated by regular blockchain transactions, such as a hash character string calculated based on the Sha256 algorithm by using the blockchain address, the user blockchain address, and the smart contract self-increment ID.

For example,// activate code: the codeHash activation code, the blockNum block height, the bcAddress user block chain address and the count are intelligent contract self-increment IDs; bytes32codeHash is taken to be keccak256(blockNum + bcAddress + count). Where keccak256 is an algorithmic implementation of Sha 256. According to the embodiment of the invention, in order to avoid the situation that the activation code is generated next time and is repeated with the generated activation code, the count automatically changes a new ID number every time a new activation code is generated, and the generated new ID number is the current intelligent contract self-increment ID.

By the embodiment of the invention, the intelligent contract of the activation code is deployed on the block chain platform, so that the management cost for generating the activation code and verifying the activation code in a centralized management mode can be saved; meanwhile, the activation codes are removed from the center, the total number of the activation codes is determined, and the rules are determined, so that the fairness, the justness and the transparency of the activation codes of the products can be ensured; on a block chain platform, all the activation codes are public, nobody can steal the activation codes, and the information is transparent.

According to the embodiment of the invention, the target activation code is generated based on the activation code generation request through the block chain platform, and the activation code management center sends the target activation code to the client, so that the activation code can be managed in a centralized manner, and any third party cannot change the rules and the total number of the activation code at will. The activation code rule is publicly transparent to the user; for products, a fair, fair and transparent activation management environment can be provided, so that the possibility that a manager randomly modifies the total number of activation codes and the verification rule is remarkably reduced, and better experience is brought to users.

FIG. 5 schematically shows a flow diagram of an activate code generation method according to another embodiment of the invention.

According to the embodiment of the invention, the intelligent contract further comprises an activation code verification contract, and as shown in fig. 5, the activation code generation method comprises operations S510 to S520.

In operation S510, an activation code verification request sent by the client and signed by using a private key corresponding to the user block chain address is obtained.

In operation S520, the user blockchain address is verified according to the activation code verification contract in response to the activation code verification request.

According to an embodiment of the present invention, the private key format of the user block chain address may be 2fb7fd4eb832bbb06ca3d04201d4c06a243aea6eec8214dbbe7626b6d5607f 90.

According to the embodiment of the invention, the invention does not limit the specific activation code verification mode. Specifically, for example, the validation rule may be to validate at least one of: user identification information such as other universal unique identification codes such as a user account, a mac address and an ip address, the number of times that a single activation code can be activated, and the like.

According to the embodiment of the invention, a user can input the activation code and the private key at the client side of the activation code, the client side initiates an activation code verification request to the block chain platform after the client side passes the private key signature verification, the block chain platform passes the verification, the block is successfully discharged, and the product can be activated.

According to the embodiment of the invention, all the activation codes are transparent on the block chain, and the activation codes can only be used by a holder with a private key, so that the activation codes cannot be abused by people to activate the software of other people.

According to the embodiment of the invention, under the condition that the verification result obtained by verifying the user block chain address according to the activation code verification contract shows that the verification is successful, the user identification information corresponding to the user block chain address and the current verification times of the target activation code are stored in the block chain.

According to the embodiment of the invention, after the user block chain address passes the verification, the block chain platform can store the verified information on the block chain and the node database of the block chain platform, wherein the verified information comprises general user identification information, the number of times of user activation and the like, and can be used for disclosing the activated information and checking the activated information at the next activation.

The method illustrated in FIG. 2 is further described with reference to FIG. 6 in conjunction with specific embodiments.

FIG. 6 schematically shows a flow diagram of an activate code management method according to another embodiment of the invention. In this embodiment, operations S610 through S630 are included in addition to operations S210 through S230 described above with reference to FIG. 2. The description of operations S210 to S230 is omitted herein for the sake of brevity of description.

As shown in FIG. 6, before sending the target activation code to the client, the activation code management method further includes operations S610-S630.

In operation S610, one or more blocks generated by a blockchain platform and one or more activate target codes are obtained, wherein attribute information of the activate target codes is recorded in the one or more blocks.

Because the query function of the blockchain is weak, such as transaction that all activation codes cannot be directly queried and statistics on the use condition of the activation codes cannot be carried out, according to the embodiment of the invention, the activation code management center can export one or more blocks generated by the blockchain platform and one or more target activation codes to the database. Specifically, the activation code management center can export all the activation codes to be saved in the database by calling an activation code export method of the intelligent contract. The boot code management center may obtain one or more blocks by downloading all blocks of the blockchain platform.

In operation S620, each block in the block chain is parsed to obtain attribute information of one or more target activate codes.

According to the embodiment of the invention, by analyzing the activation transaction in the block, the attribute information of one or more target activation codes can be obtained, and the attribute information can be information related to parameters and results of acquisition transaction and verification activation transaction of the activation codes.
