本发明属于加密数字货币技术领域，具体涉及一种用于加密数字货币的公钥地址与用户账号的关联和检索方法及其系统。The invention belongs to the technical field of encrypted digital currency, and in particular relates to a method for associating and retrieving public key addresses of encrypted digital currency and user accounts and a system thereof.
背景技术Background technique
近年来，以全球公开账本(如区块链技术)为基础的各种加密数字货币(Crypto Currency)，如比特币、莱特币、狗狗币等，开始在因特网上大量使用和流行，日交易额超过千万美元，并且在不断增长中。目前已有维基百科、戴尔电脑、新蛋、PayPal等著名公司和机构支持使用以比特币为代表的加密数字货币支付来作为交易方式。In recent years, various encrypted digital currencies (Crypto Currency) based on global public ledgers (such as blockchain technology), such as Bitcoin, Litecoin, Dogecoin, etc., have begun to be widely used and popular on the Internet. Daily transactions The amount exceeds 10 million U.S. dollars and continues to grow. At present, well-known companies and institutions such as Wikipedia, Dell Computer, Newegg, and PayPal support the use of encrypted digital currency payment represented by Bitcoin as a transaction method.
虽然比特币等加密数字货币存在较多的社会争议，但其采用的技术手段具有很高的创新价值。典型的加密数字货币使用的公开账本是一套基于工作量证明(Proof-of-Work)机制的分布式存储方案，通常具有极高的安全性和抗攻击特性。例如，要对比特币的公开账本(即比特币区块链)的安全性形成有效挑战，需要高达数千TH/s以上的计算能力，这已经超过了当前全球前500强超级计算机的计算能力总和的百倍。Although there are many social controversies in encrypted digital currencies such as Bitcoin, the technical means used in them have high innovation value. The public ledger used by a typical encrypted digital currency is a distributed storage solution based on the Proof-of-Work mechanism, which usually has extremely high security and anti-attack characteristics. For example, to effectively challenge the security of Bitcoin's public ledger (that is, the Bitcoin blockchain), a computing power of thousands of TH/s is required, which has exceeded the computing power of the current top 500 supercomputers in the world A hundred times the sum.
要使用加密数字货币完成转账交易，发送方需要提前获取接收方的公钥地址，并用自己的私钥完成交易。加密数字货币的公钥地址通常由随机的大小写字母和数字组成，且长度较长，例如，比特币的典型公钥地址长度为34个字符，极不方便辨别、记忆、拷贝和转抄，在录入过程中非常容易出错。通常来说，囿于加密数字货币的技术原理，处于被使用状态的公钥地址远远小于所有公钥地址的总数。因此常有发生由于地址输入错误，导致发送方将币发送到了错误的或不存在的公钥地址，造成了不可挽回的经济损失。To use encrypted digital currency to complete the transfer transaction, the sender needs to obtain the receiver's public key address in advance and complete the transaction with its own private key. The public key address of encrypted digital currency is usually composed of random uppercase and lowercase letters and numbers, and the length is relatively long. For example, the typical public key address of Bitcoin is 34 characters long, which is extremely inconvenient to identify, remember, copy and transcribe. It is very easy to make mistakes during the entry process. Generally speaking, due to the technical principles of encrypted digital currency, the public key addresses in use are far less than the total number of all public key addresses. Therefore, it often happens that the sender sends the currency to the wrong or non-existent public key address due to the wrong input of the address, resulting in irreparable economic losses.
针对上述问题，现有技术提出一种通过二维码图片传递公钥地址，降低出错率。但此方法受到的限制较多，在许多情况下较为不便，例如需要生成和保存图片，并完成拍摄、打印和图片传送，仍然难以用于日常场景下快捷的交流和记忆。In view of the above problems, the prior art proposes a way to transmit the public key address through a two-dimensional code image to reduce the error rate. However, this method has many limitations and is inconvenient in many cases. For example, it needs to generate and save pictures, and complete shooting, printing and picture transmission. It is still difficult to use for quick communication and memory in daily scenes.
同时，在线交易中交易双方的信任问题是收到广泛关注的问题，在加密数字货币的领域里因为公钥地址的匿名性，无法有效地将地址与个人真是身份有效地关联起来，这使得发款方容易担心收款方是否会抵赖收款，从而造成部分交易因为信任问题未能达成。At the same time, the issue of trust between the two parties in online transactions has received widespread attention. In the field of encrypted digital currency, due to the anonymity of the public key address, it is impossible to effectively associate the address with the real identity of the individual. The payer is likely to worry about whether the payee will deny the payment, which will cause some transactions to fail due to trust issues.

具体实施方式Detailed ways
如图1所示，在由一个公开账本和n个用户构成的加密数字货币网络中，n个用户共享同一套公开账本(如比特币的区块链，即Block Chain)，在用户的计算机中存储公开账本的全部或部分副本。公开账本具有极高的安全性，其安全性由工作量证明(Proof-of-work)等机制进行保护。如图1中，用户的所有交易会向全网的其他用户广播，最终进入公开账本中。公开账本用于存储并公开n个用户的交易记录，每条交易记录的内容包括交易编号、交易时间、发送方和接收方的公钥地址，发送加密数字货币的数量、交易手续费、附加信息或脚本内容等；n个用户拥有各自不同的公钥地址和私钥地址，这些公钥地址和私钥地址成对存在，使用私钥地址可以生成公钥地址，反之则不可以，可以很方便地使用私钥地址来验证用户对某个公钥地址的所有权；公钥地址用于公布并接收加密数字货币，私钥地址用于签名并发送加密数字货币；As shown in Figure 1, in an encrypted digital currency network consisting of a public ledger and n users, n users share the same set of public ledgers (such as Bitcoin’s blockchain, or Block Chain), and in the user’s computer Store a full or partial copy of the public ledger. The public ledger has extremely high security, and its security is protected by mechanisms such as Proof-of-work. As shown in Figure 1, all transactions of the user will be broadcast to other users in the entire network, and finally entered into the public ledger. The public ledger is used to store and disclose the transaction records of n users. The content of each transaction record includes the transaction number, transaction time, public key addresses of the sender and receiver, the amount of encrypted digital currency sent, transaction fees, and additional information Or script content, etc.; n users have their own different public key addresses and private key addresses, these public key addresses and private key addresses exist in pairs, using the private key address can generate a public key address, and vice versa, it can be very convenient Use the private key address to verify the user's ownership of a public key address; the public key address is used to publish and receive encrypted digital currency, and the private key address is used to sign and send encrypted digital currency;
一种用于加密数字货币的公钥地址与用户账号的关联和检索方法是按如下过程进行：A method for associating and retrieving a public key address of an encrypted digital currency with a user account is carried out as follows:
步骤1、向加密数字货币网络中的用户公布验证公钥地址；公布验证公钥地址的方式有网站公开、微博公开、微信公众号等。为方便识别，可采用VanityGen等工具生成包含有特殊字符串的公钥地址。Step 1. Publish the verification public key address to users in the encrypted digital currency network; the methods of publishing the verification public key address include website disclosure, Weibo disclosure, WeChat official account, etc. For easy identification, tools such as VanityGen can be used to generate public key addresses containing special strings.
步骤2、建立已注册用户：Step 2. Create a registered user:
步骤2.1、接收待注册用户的注册账号请求并进行验证，验证条件有：Step 2.1. Receive and verify the registration account request of the user to be registered. The verification conditions are as follows:
(1)账号名不得为被禁止注册的账号名，如保留字、长度少于4的账号名，以及带有攻击或侮辱性字样的账号名；(1) Account names must not be account names that are prohibited from registration, such as reserved words, account names with a length of less than 4, and account names with offensive or insulting words;
(2)账号名、邮箱地址不得与已有账号名、邮箱地址重复。(2) The account name and email address must not be the same as the existing account name and email address.
步骤2.2、对通过验证的注册账号接收其加密数字货币的公钥地址，加密数字货币的公钥地址可以是多种加密数字货币的多个公钥地址，从而建立已注册用户，在数据库中记录注册用户的账号名和注册用户的公钥地址，使得注册账号与公钥地址建立对应关系；Step 2.2. Receive the public key address of encrypted digital currency for the verified registered account. The public key address of encrypted digital currency can be multiple public key addresses of multiple encrypted digital currencies, so as to establish registered users and record them in the database The account name of the registered user and the public key address of the registered user establish a corresponding relationship between the registered account and the public key address;
如果用户输入的是已被其他用户登记过的公钥地址，提示用户检查是否输入了错误的公钥地址，若是，则重新输入，若不是，则通过以下方式之一进行申诉：If the user enters a public key address that has been registered by other users, the user is prompted to check whether the wrong public key address has been entered. If so, re-enter it. If not, appeal in one of the following ways:
(1)人工申诉：通过电话、电子邮件、QQ等方式进行人工核验；(1) Manual appeal: manual verification by telephone, email, QQ, etc.;
(2)自动申诉：提示用户在限定的时间内(如15分钟)，使用其输入的公钥地址对应的私钥地址发送一笔极小额的加密数字货币至特定的公钥地址，以证明用户对公钥地址及对应的私钥地址的所有权。(2) Automatic appeal: Prompt the user to use the private key address corresponding to the public key address entered to send a very small amount of encrypted digital currency to a specific public key address within a limited period of time (such as 15 minutes) to prove The user's ownership of the public key address and the corresponding private key address.
对申诉成功的用户，将其账号与其输入的公钥地址的关联，同时解除该公钥地址与其他用户的绑定。For users who have successfully appealed, their account will be associated with the public key address they entered, and the public key address will be unbound from other users at the same time.
步骤2.3、对已注册用户进行身份认证，使得已注册用户为真实合法用户，从而将用户账号、公钥地址与用户的真实身份建立起对应关系。Step 2.3: Perform identity authentication on the registered user, so that the registered user is a real and legal user, so as to establish a corresponding relationship between the user account, the public key address and the user's real identity.
本实施例中，引导已注册用户使用电子邮箱、手机、微博和QQ号进行身份认证。其中电子邮箱的认证方法为：向其邮箱发送带有特殊链接的电子邮件，用户打开电子邮件点击该链接后即完成电子邮箱认证。手机认证的方法为：向手机发送带有验证码的短消息，用户在账号手机验证界面中，输入正确的手机验证码，即可通过手机认证。微博和QQ号的认证方式为：通过微博和QQ开发的OAUTH认证接口API，由用户输入其拥有的微博和QQ账号、密码并授权，即可通过微博和QQ认证；In this embodiment, the registered user is guided to use email, mobile phone, Weibo and QQ number for identity authentication. The email authentication method is as follows: send an email with a special link to the email, and the user opens the email and clicks on the link to complete the email authentication. The method of mobile phone authentication is as follows: send a short message with a verification code to the mobile phone, and the user enters the correct mobile phone verification code in the account mobile phone verification interface to pass the mobile phone verification. The authentication method of Weibo and QQ accounts is as follows: through the OAUTH authentication interface API developed by Weibo and QQ, users can enter their own Weibo and QQ account numbers and passwords and authorize them to pass Weibo and QQ authentication;
具体实施中，步骤1和步骤2的顺序可以互换。In specific implementation, the order of step 1 and step 2 can be interchanged.
步骤3、利用与验证公钥地址对应的私钥地址向任意其他公钥地址发送数量大于等于零的加密数字货币作为已注册用户的验证交易并记录在公开账本中形成交易编号，设置验证交易的附加信息或脚本内容中包含校验数据；本实施例中，采用比特币交易中的脚本类型为OP_RETURN的脚本内容存放校验数据。图2给出了验证交易的示意框图。图中发送方的验证公钥地址即为步骤1中向用户公布的验证公钥地址，接收方地址可为任意公钥地址。校验数据按照如下方式获得：Step 3. Use the private key address corresponding to the verification public key address to send an encrypted digital currency with a quantity greater than or equal to zero to any other public key address as the verification transaction of the registered user and record it in the public ledger to form a transaction number, and set the additional value of the verification transaction The information or script content contains verification data; in this embodiment, the script content in the bitcoin transaction whose script type is OP_RETURN is used to store the verification data. Figure 2 shows a schematic block diagram of a verified transaction. The verification public key address of the sender in the figure is the verification public key address announced to the user in step 1, and the receiver address can be any public key address. The verification data is obtained as follows:
将已注册用户的账号信息和/或已注册用户的公钥地址进行组合后通过哈希值运算，生成固定长度范围的数据作为校验数据；账号信息包括：注册账号和/或真实身份信息。例如，真实身份信息可包括：姓名、性别、手机号、电子邮箱地址等。本实施例中，对用户的账号名和公钥地址组合为JSON格式，如The account information of the registered user and/or the public key address of the registered user are combined and hash value operation is performed to generate fixed-length data as verification data; the account information includes: registered account number and/or real identity information. For example, real identity information may include: name, gender, mobile phone number, email address, etc. In this embodiment, the combination of the user's account name and public key address is in JSON format, such as
}其中user字段表示用户账号名，gender、phone、email字段分别标注了用户的性别、手机号和电子邮箱地址，addresses字段表示用户的公钥地址列表，例如type为BTC表示比特币公钥地址，type为LTC表示公钥莱特币地址。将上述JSON格式内容去除换行和空格后，并采用SHA-256算法进行哈希运算，得到结果为固定长度32byte(256bit)的数据：} where the user field represents the user account name, the gender, phone, and email fields mark the user's gender, mobile phone number, and email address respectively, and the addresses field represents the user's public key address list, for example, if the type is BTC, it represents the Bitcoin public key address, type is LTC means public key Litecoin address. After removing newlines and spaces from the content in the above JSON format, and using the SHA-256 algorithm for hashing, the result is fixed-length 32byte (256bit) data:
25b36695d9dfcf54532a940ec49f39352b04a7c66c2ea0fe5b7c16fa1eb88cbc25b36695d9dfcf54532a940ec49f39352b04a7c66c2ea0fe5b7c16fa1eb88cbc
再在最前端增加一个特殊前缀“BIDIZHI”的ascii编码：424944495a484940，用以与其他脚本内容的前缀进行区分。组合在一起，即为：Then add a special prefix "BIDIZHI" ascii code at the front: 424944495a484940 to distinguish it from other script content prefixes. Combined together, it is:
424944495a48494025b36695d9dfcf54532a940ec49f39352b04a7c66c2ea0fe5b7c16fa1eb88cbc424944495a48494025b36695d9dfcf54532a940ec49f39352b04a7c66c2ea0fe5b7c16fa1eb88cbc
上述内容即作为验证交易的类型为OP_RETURN的脚本内容。The above content is the script content of the verification transaction type OP_RETURN.
步骤4、接收来自加密数字货币网络中其他用户的查询请求，查询请求为查询已注册用户的公钥地址的请求；具体实施中，查询请求由用户在浏览器网页中提交，对用户提交的内容进行判断，是否在数据库中存在查询请求的用户账号名，若不存在则提示用户未找到。若存在，根据查询请求反馈已注册用户的公钥地址，并在公开账本中根据交易编号检索是否存在已注册用户的验证交易；具体实施中，根据数据库中记录的交易编号，在比特币区块链中使用GetTransaction(txid)命令接口进行检索，其中txid即为交易编号。若不存在，则表示已注册用户的公钥地址为可疑地址并进行提示；若存在，则校验已注册用户的验证交易的发送方是否为验证公钥地址的公布方；若不是，则表示已注册用户的公钥地址为非法地址并进行提示；若是，则检查验证交易的附加信息或脚本内容中，是否包含校验数据；若不包含，则表示已注册用户的公钥地址为非法地址并进行提示；若包含，则核对校验数据是否一致；若一致，则表示已注册用户的公钥地址为安全有效地址，否则，表示已注册用户的公钥地址为非法地址并进行提示。具体实施中，调取用户的账号信息和公钥地址，组成JSON格式的数据，使用SHA-256算法对其进行哈希运算，将运算得到的结果前附加特殊前缀“BIDIZHI”的ascii编码，即424944495a484940，再与区块链中的验证消息的OP_RETURN脚本内容中的数据进行对比，判断是否完全一致即可。采用这种方式的优点在于，数据源是本地数据库，所以响应速度快，用户体验较好。在返回本地数据库中保存的地址之后再到公开账本进行验证，给出验证结果的提示，用户能以最快速度查询到检索的账号名对应的公钥地址，因为绝大多数情况下，用户的公钥地址不会被攻击或冒用；但是技术实现上相对复杂。Step 4. Receive query requests from other users in the encrypted digital currency network. The query requests are requests for querying the public key addresses of registered users; It is judged whether the user account name of the query request exists in the database, and if it does not exist, it will prompt the user that it is not found. If it exists, feed back the public key address of the registered user according to the query request, and search whether there is a verification transaction of the registered user in the public ledger according to the transaction number; in specific implementation, according to the transaction number recorded in the database, in the Bitcoin block Use the GetTransaction(txid) command interface in the chain to retrieve, where txid is the transaction number. If it does not exist, it means that the public key address of the registered user is a suspicious address and prompts; if it exists, it checks whether the sender of the verification transaction of the registered user is the publisher of the verification public key address; if not, it means The public key address of the registered user is an illegal address and a prompt is given; if so, check whether the verification data is included in the additional information or script content of the verification transaction; if not, it means that the public key address of the registered user is an illegal address And prompt; if it is included, check whether the verification data is consistent; if consistent, it means that the public key address of the registered user is a safe and valid address, otherwise, it means that the public key address of the registered user is an illegal address and prompts. In the specific implementation, the user's account information and public key address are retrieved to form data in JSON format, and the SHA-256 algorithm is used to perform hash operations on it, and the ascii code with the special prefix "BIDIZHI" is added to the result obtained after the operation, that is 424944495a484940, and then compare it with the data in the OP_RETURN script content of the verification message in the blockchain to determine whether it is completely consistent. The advantage of using this method is that the data source is a local database, so the response speed is fast and the user experience is better. After returning the address saved in the local database, it will go to the public account book for verification, and a prompt of the verification result will be given. The user can query the public key address corresponding to the retrieved account name at the fastest speed, because in most cases, the user's The public key address will not be attacked or fraudulently used; however, the technical implementation is relatively complicated.
除了以上这种方式外，步骤4还可以按如下方式进行：In addition to the above method, step 4 can also be performed as follows:
接收来自加密数字货币网络中其他用户的查询请求，具体实施中，查询请求由用户在浏览器网页中提交，对用户提交的内容进行判断，是否在数据库中存在查询请求的用户账号名，若不存在则提示用户未找到。若存在，查询请求为查询已注册用户的公钥地址的请求；根据查询请求在公开账本中根据交易编号检索是否存在已注册用户的验证交易；具体实施中，根据数据库中记录的交易编号，在比特币区块链中使用GetTransaction("txid")命令进行检索，其中txid即为交易编号。若不存在，则表示已注册用户的公钥地址为可疑地址；若存在，则校验已注册用户的验证交易的发送方是否为验证公钥地址的公布方；若不是，则表示已注册用户的公钥地址为非法地址；若是，则检查验证交易的附加信息或脚本内容中，是否包含校验数据；若不包含，则表示已注册用户的公钥地址为非法地址；若包含，则核对校验数据是否一致；若一致，则表示已注册用户的公钥地址为安全有效地址并反馈已注册用户的公钥地址，否则，表示已注册用户的公钥地址为非法地址。采用这种方式的优点在于技术实现相对简单，对数据库存储空间要求也略低一些。但因为需要先去公开账本查询，查询的响应速度相比第前一种方式较慢，用户体验也有所下降。Receive query requests from other users in the encrypted digital currency network. In the specific implementation, the query request is submitted by the user in the browser webpage, and the content submitted by the user is judged to see whether the user account name of the query request exists in the database. If it exists, the user will be prompted that it is not found. If it exists, the query request is a request to query the public key address of the registered user; according to the query request, search whether there is a verification transaction of the registered user according to the transaction number in the public ledger; in specific implementation, according to the transaction number recorded in the database, in Use the GetTransaction("txid") command in the Bitcoin blockchain to retrieve, where txid is the transaction number. If it does not exist, it means that the public key address of the registered user is a suspicious address; if it exists, check whether the sender of the verification transaction of the registered user is the publisher of the verification public key address; if not, it means that the registered user The public key address of the registered user is an illegal address; if so, check whether the verification data is included in the additional information or script content of the verification transaction; if not included, it means that the public key address of the registered user is an illegal address; if it is included, check Check whether the data is consistent; if they are consistent, it means that the public key address of the registered user is a safe and valid address and feedback the public key address of the registered user, otherwise, it means that the public key address of the registered user is an illegal address. The advantage of using this method is that the technical implementation is relatively simple, and the requirements for database storage space are slightly lower. However, because it is necessary to open the account book first, the response speed of the query is slower than the first method, and the user experience has also declined.
参见图3，一种用于加密数字货币公钥地址与用户账号关联和检索的系统包括：Referring to Figure 3, a system for associating and retrieving encrypted digital currency public key addresses with user accounts includes:
客户端，用于接收系统用户提供注册和登陆账号、接收新的用户检索已有用户用于接收加密电子货币的公钥地址的请求，并向服务端发起请求，获取服务端的处理结果，向系统用户呈现服务端处理结果的功能。The client is used to receive the registration and login account provided by the system user, receive the request from the new user to retrieve the public key address of the existing user for receiving encrypted electronic currency, and initiate a request to the server, obtain the processing result of the server, and send the request to the system The user presents the function of server-side processing results.
服务端，包括注册和验证单元、验证交易单元以及查询和检索单元。具体实施中，服务端使用C#语言实现，开发环境为Visual Studio2013。服务端采用Asp.Net MVC网站开发技术，部署于IIS7网站容器供用户访问。数据库部分使用My SQL5.6，存储引擎为InnoDB。The server includes a registration and verification unit, a transaction verification unit, and a query and retrieval unit.
