技术领域technical field
本发明涉及区块链技术领域，特别是涉及一种生物特征数据的分享方法、分享系统和计算机设备。The present invention relates to the technical field of blockchain, in particular to a method, a sharing system and computer equipment for sharing biometric data.
背景技术Background technique
随着各种可穿戴装置的发展，诸如血压、心率、血糖、体温等基础医学数据的测量和获取越来越简单，例如apple watch、samsung gear等智能手表可以持续的提供心率等生物特征数据，然而如何实现这些海量的医学数据的集中利用在实践中并无成功的解决方案。With the development of various wearable devices, the measurement and acquisition of basic medical data such as blood pressure, heart rate, blood sugar, and body temperature are becoming easier and simpler. For example, smart watches such as apple watch and samsung gear can continuously provide biometric data such as heart rate. However, how to realize the centralized utilization of these massive medical data has no successful solution in practice.
对于需要这些数据的医学研究机构而言，付费不是问题，但如何获取来源于多个提供商的数据以及如何鼓励数据的产生者持续、主动的产出这些生物特征数据是难以处理的。对于用户而言，由于花钱买了这些智能穿戴设备，如果没有利益的刺激，没有动机将自身的生物特征数据与研究机构进行分享。对于生产和销售这些智能穿戴设备的厂商而言，诸如三星等并不具备也不需求医学和健康的科研需求，因此如果没有经济利益的刺激，没有动机去收集这些用户测量产生的数据，因为维护和运营这样的云服务需要的成本是非常巨大的。For medical research institutions that need this data, payment is not a problem, but how to obtain data from multiple providers and how to encourage data producers to continuously and actively produce these biometric data is difficult to deal with. For users, because they spend money on these smart wearable devices, if there is no incentive to benefit, there is no incentive to share their biometric data with research institutions. For manufacturers who produce and sell these smart wearable devices, such as Samsung, they do not have and do not need medical and health research needs, so if there is no incentive for economic benefits, there is no incentive to collect the data generated by these user measurements, because maintenance And the cost of running such a cloud service is huge.
此外，生物特征数据的分享是非常敏感的，需要满足卫计委制定的相关标准，必须在保持匿名、安全、可控的前提下才能进行分享和利用。In addition, the sharing of biometric data is very sensitive and needs to meet the relevant standards set by the National Health and Family Planning Commission. It must be shared and used under the premise of maintaining anonymity, security and control.

具体实施方式Detailed ways
为了更清楚地说明本发明，下面结合优选实施例和附图对本发明做进一步的说明。附图中相似的部件以相同的附图标记进行表示。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本发明的保护范围。In order to illustrate the present invention more clearly, the present invention will be further described below with reference to the preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
随着互联网技术的发展，区块链技术应运而生，这是一种分布式数据库技术，具有去中心化、公开透明的特征。具体地，区块链技术的本质是去中心化且采用分布式结构的数据存储、传输和证明的方法，用数据区块取代目前互联网对中心服务器的依赖，使得所有数据的变更或者交易项目都被记录在一个数据链表之上。极大提高数据运算、管理、维护效率，同时搭载非对称加密技术的区块链具备高安全性，能有效防止数据泄露或非法篡改。上述特点使得区块链技术特别适合应用于具有高度保密要求的大数据运算领域。With the development of Internet technology, blockchain technology came into being, which is a distributed database technology with the characteristics of decentralization, openness and transparency. Specifically, the essence of blockchain technology is a decentralized and distributed data storage, transmission and proof method, replacing the current Internet dependence on the central server with data blocks, so that all data changes or transaction items are are recorded on a data linked list. It greatly improves the efficiency of data operation, management and maintenance. At the same time, the blockchain equipped with asymmetric encryption technology has high security and can effectively prevent data leakage or illegal tampering. The above characteristics make blockchain technology particularly suitable for applications in the field of big data computing with high confidentiality requirements.
然而，在实际应用中，技术人员基于区块链技术开发区块链应用存在较大难度，基于该问题推出了以太坊平台，所述以太坊平台为可以共享的开源区块链底层技术的平台。换句话说，以太坊类似于已经开发完成的系统平台，并向所有区块链开发技术人员开源，使得后续技术人员能够在以太坊平台的底层技术上十分便捷的开发新的区块链应用。同时，以太坊平台还引入了智能合约，所谓智能合约，是一种用计算机语言取代法律语言去记录条款的合约，可视作一段部署在区块链上的程序，具有自我执行和自我强制属性。自我执行是指合约在部署后自动运行生效；自我强制是指参与方能够调用合约使其在满足条件情况下强制执行。整个决策过程不需要可信的第三方参与仲裁干预。由区块链技术保证数据的真实有效和智能合约的不可篡改性，而智能合约负责强制执行规范，使得区块链技术特征与交通拥堵共享的应用需求具有良好的结合点，可以避免中心化平台带来的隐私泄露弊端，并可通过激励措施鼓励司机分享拥堵信息。智能合约的出现让区块链技术得以开始在一些商业应用上得以落地。目前很多区块链在商业运用中通过智能合约来实现基本的区块链技术。However, in practical applications, it is difficult for technicians to develop blockchain applications based on blockchain technology. Based on this problem, the Ethereum platform was launched, which is a platform for sharing the underlying technology of open source blockchains. . In other words, Ethereum is similar to a system platform that has been developed and is open sourced to all blockchain development technicians, so that subsequent technicians can easily develop new blockchain applications on the underlying technology of the Ethereum platform. At the same time, the Ethereum platform also introduces smart contracts. The so-called smart contract is a contract that uses computer language to replace legal language to record terms. It can be regarded as a program deployed on the blockchain, with self-execution and self-enforcement properties. . Self-execution means that the contract will automatically run and take effect after deployment; self-enforcement means that participants can invoke the contract to enforce it when conditions are met. The entire decision-making process does not require a trusted third party to participate in arbitration intervention. The authenticity and validity of data and the immutability of smart contracts are guaranteed by blockchain technology, while smart contracts are responsible for enforcing specifications, making the technical features of blockchain and the application requirements of traffic congestion sharing a good combination, which can avoid centralized platforms. It brings the disadvantages of privacy leakage, and can encourage drivers to share congestion information through incentives. The emergence of smart contracts has allowed blockchain technology to begin to be implemented in some commercial applications. At present, many blockchains implement basic blockchain technology through smart contracts in commercial applications.
基于区块链技术，为解决现有生物特征数据的采集和收集问题，如图1所示，本发明的一个实施例提供了一种生物特征数据分享方法，包括：生物特征数据采集端采集生物特征数据并生成数据包，通过第一密码加密后生成第一智能合约并发布到区块链网络；生物特征数据收集端基于所述第一智能合约生成第二智能合约并发布到区块链网络，所述第二智能合约包括多个所述第一智能合约和各第一智能合约对应的合约信息；生物特征数据购买端触发所述第二智能合约并支付所述第二智能合约对应的合约费用；所述第二智能合约根据各所述合约信息生成所述多个第一智能合约的第一密码，根据所述生物特征数据购买端的公钥加密所述多个第一密码并发送至所述生物特征数据购买端；所述生物特征数据购买端通过其私钥进行解密并获取所述多个第一密码，根据所述多个第一密码获取对应的第一智能合约的数据包，并发送解密确认信息至所述第二智能合约；所述第二智能合约基于所述解密确认信息，根据所述合约信息分配所述合约费用。Based on the blockchain technology, in order to solve the problem of collecting and collecting existing biometric data, as shown in FIG. 1 , an embodiment of the present invention provides a method for sharing biometric data, including: a biometric data collection end collects biometric data. Feature data and generate a data package, generate a first smart contract after encrypting with the first password and publish it to the blockchain network; the biometric data collection end generates a second smart contract based on the first smart contract and publishes it to the blockchain network , the second smart contract includes a plurality of the first smart contracts and contract information corresponding to each first smart contract; the biometric data purchaser triggers the second smart contract and pays the contract corresponding to the second smart contract fee; the second smart contract generates the first passwords of the plurality of first smart contracts according to the contract information, encrypts the plurality of first passwords according to the public key of the buyer of the biometric data, and sends it to the The biometric data purchaser; the biometric data purchaser decrypts through its private key and obtains the plurality of first passwords, and obtains the data package of the corresponding first smart contract according to the plurality of first passwords, and Send decryption confirmation information to the second smart contract; the second smart contract allocates the contract fee according to the contract information based on the decryption confirmation information.
生物特征数据采集端、生物特征数据收集端和生物特征数据购买端均为区块链上的节点，地位平等。The biometric data collection end, the biometric data collection end and the biometric data purchase end are all nodes on the blockchain, with equal status.
其中，生物特征数据采集端为可穿戴监控装置，例如为智能手环、智能手表等，能够监测穿戴用户的心率、血压和体温等生物特征数据；在本实施例中，所述生物特征数据采集端为智能手环，智能手环按照预定的时间间隔采集用户的生物特征数据，并根据采集的生物特征数据生成数据包，通过第一密码加密生成第一智能合约并发布到区块链网络中，所述第一密码可以为按照一定规则生成的密码，例如可以为根据智能手环的MAC ID等信息生成的密码。Among them, the biometric data collection terminal is a wearable monitoring device, such as a smart bracelet, a smart watch, etc., which can monitor the biometric data such as the heart rate, blood pressure and body temperature of the wearing user; in this embodiment, the biometric data collection The terminal is a smart bracelet. The smart bracelet collects the user's biometric data at a predetermined time interval, generates a data package according to the collected biometric data, and encrypts the first smart contract with the first password and publishes it to the blockchain network. , the first password may be a password generated according to certain rules, for example, may be a password generated according to information such as the MAC ID of the smart bracelet.
在一个可选的实施例中，所述时间间隔大于等于所述区块链网络的节点验证时间。即第一智能合约的发布频率应小于区块链的节点验证效率，例如区块链的节点验证效率为每秒x个事务，则第一智能合约的打包频率小于每秒x个数据包。考虑到生物特征数据具有一定时间的稳定性，例如心率数据一般按照一分钟测量的数据进行考量，在本实施例中，所述时间间隔为一分钟。In an optional embodiment, the time interval is greater than or equal to the node verification time of the blockchain network. That is, the release frequency of the first smart contract should be less than the node verification efficiency of the blockchain. For example, if the node verification efficiency of the blockchain is x transactions per second, the packaging frequency of the first smart contract is less than x data packets per second. Considering that the biometric data has a certain time stability, for example, the heart rate data is generally considered according to the data measured in one minute. In this embodiment, the time interval is one minute.
生物特征数据收集端为生物特征数据采集端的生产厂商或服务厂商的监控装置，用于监控生物特征数据采集端发布的第一智能合约，基于第一智能合约生成第二智能合约并发布到区块链网络上，例如收集一定数量的第一智能合约将其打包为第二智能合约，即使用第二智能合约封装多个第一智能合约，第二智能合约还包括第一智能合约的合约信息，例如标识第一智能合约的用户信息和表征费用分配的费用信息。The biometric data collection end is a monitoring device of the manufacturer or service provider of the biometric data collection end, which is used to monitor the first smart contract issued by the biometric data collection end, generate a second smart contract based on the first smart contract and publish it to the block On the chain network, for example, a certain number of first smart contracts are collected and packaged into second smart contracts, that is, multiple first smart contracts are encapsulated by the second smart contract, and the second smart contract also includes the contract information of the first smart contract. For example, user information identifying the first smart contract and fee information characterizing fee distribution.
生物特征数据购买端为需要大量生物特征数据的研发机构或企业，通过支付合约费用的形式触发第二智能合约，第二智能合约执行合约内容，根据包括的第一智能合约的合约信息生成解密第一智能合约的第一密码，然后利用区块链的非对称加密技术，将各第一密码利用生物特征数据购买端的公钥进行加密并传输至生物特征数据购买端，使得生物特征数据购买端利用私钥解密各第一智能合约并获取第一智能合约中的生物特征数据。同时，在生物特征数据购买端解密第一智能合约获取生物特征数据后，第二智能合约根据合约信息中的费用信息分配合约费用，将属于用户的费用直接支付至生物特征数据采集端，同时将其余费用支付给收集第一智能合约的生物特征数据收集端，即生产厂商或服务厂商。The biometric data purchaser is a research and development institution or enterprise that needs a large amount of biometric data. The second smart contract is triggered by paying the contract fee. The second smart contract executes the contract content, and generates and decrypts the first smart contract according to the contract information included in the first smart contract. The first password of a smart contract, and then using the asymmetric encryption technology of the blockchain, each first password is encrypted with the public key of the biometric data purchaser and transmitted to the biometric data purchaser, so that the biometric data purchaser can use the The private key decrypts each first smart contract and obtains the biometric data in the first smart contract. At the same time, after decrypting the first smart contract at the biometric data purchaser to obtain the biometric data, the second smart contract allocates contract fees according to the fee information in the contract information, and directly pays the fees belonging to the user to the biometric data collection terminal. The rest of the fees are paid to the biometric data collection end that collects the first smart contract, that is, the manufacturer or service provider.
在本实施例中，通过区块链的去中心化、可靠的安全性保护提供生物特征数据的用户隐私、生物特征数据的安全传输，同时满足了相关法律法规的要求；同时利用嵌套的智能合约和区块链的透明交易的特点将费用直接支付给用户，避免由生产厂商或服务厂商间接转账的问题。In this embodiment, the user privacy of biometric data and the secure transmission of biometric data are provided through the decentralized and reliable security protection of the blockchain, and the requirements of relevant laws and regulations are met at the same time; The transparent transaction features of contracts and blockchains pay fees directly to users, avoiding the problem of indirect transfers by manufacturers or service providers.
考虑到生物特征数据的传输需要更快的交易速度、更好的隐私保护以及更低的交易成本，因此可以由具有写入权限的企业或机构构建私有链，在私有链上实现生物特征数据的共享。私有链一方面严格限制参与节点的资格，另一方面能够避免被恶意攻击的风险，相比中心化数据库，私有链能够防止机构内单节点故意隐瞒或者篡改数据，即使发生错误，也能够迅速发现来源。因此具有实际应用前景。Considering that the transmission of biometric data requires faster transaction speed, better privacy protection and lower transaction costs, a private chain can be constructed by enterprises or institutions with write permissions, and the biometric data can be transmitted on the private chain. shared. On the one hand, the private chain strictly limits the qualifications of participating nodes, and on the other hand, it can avoid the risk of malicious attacks. Compared with the centralized database, the private chain can prevent a single node in the organization from deliberately concealing or tampering with data, and even if an error occurs, it can be quickly discovered. source. Therefore, it has practical application prospects.
