具体实施方式
以下结合附图对本公开的示范性实施例做出说明，其中包括本公开实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本公开的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
图1是根据本公开一个实施例的数字货币交易异常的验证方法的主要步骤示意图。如图1所示，包括如下的步骤S101至步骤S102。
步骤S101：第一终端应用接收第二终端应用发送的数字货币交易信息；
步骤S102：第一终端应用根据与第一运营机构后台系统的网络连接状态，执行对应的异常判断操作，以确定数字货币交易存在异常，其中，异常判断操作为以下两种操作之一：在本地双花信息列表中查找数字货币交易信息对应的双花信息的操作、将数字货币交易信息发送到第一运营机构后台系统进行验证的操作。
第一终端应用根据与第一运营机构后台系统的网络连接状态分为：第一终端应用根据与第一运营机构后台系统未建立网络连接，以及，建立网络连接。
在一个实施例中，第一终端应用根据与第一运营机构后台系统的网络连接状态，执行对应的异常判断操作，以确定数字货币交易存在异常，具体可以包括：第一终端应用在未与第一运营机构后台系统建立网络连接的情况下，在本地双花信息列表中查找数字货币交易信息对应的双花信息，如果查找到数字货币交易信息对应的双花信息，则确定数字货币交易存在异常。
其中，第一运营机构后台系统为第一终端应用的运营机构后台。
本地双花信息列表中的双花信息是第一运营机构后台系统预先同步至第一终端应用的。
第一终端应用在联网时或进行联机业务时，从第一运营机构后台系统同步得到本地双花信息列表。例如，第一终端应用联机时，第一运营机构后台系统向第一终端应用下发双花信息，具体可在进行充值、提现、同步等流程时一并下发更新。
第一运营机构后台系统的双花信息列表可以是从其他运营机构系统同步过来的，本公开实施例可以由各个运营机构共同维护双花信息，以便实现跨运营机构双花信息核验。
本地双花信息列表存储在第一终端应用本地的安全芯片中。通过端侧安全芯片内存储双花信息，可以保证第一终端应用离线时能够进行双花信息的验证，离线是指第一终端应用未与第一运营机构后台系统建立网络连接。
在另一个实施例中，第一终端应用根据与第一运营机构后台系统的网络连接状态，执行对应的异常判断操作，以确定数字货币交易存在异常，具体可以包括：第一终端应用在与第一运营机构后台系统建立网络连接的情况下，在本地双花信息列表中查找数字货币交易信息 对应的双花信息，或者将数字货币交易信息发送到第一运营机构后台系统进行验证；如果在本地双花信息列表中查找到数字货币交易信息对应的双花信息，则确定数字货币交易存在异常，如果没查找到该对应的双花信息，则不存在异常；或者，如果第一运营机构后台系统返回的验证结果为验证不通过，则确定数字货币交易存在异常，如果返回的验证结果为验证通过，则不存在异常。
在一个实施例中，第一终端应用在与第一运营机构后台系统建立网络连接的情况下，可设置优先执行将数字货币交易信息发送到第一运营机构后台系统进行验证的操作。
在确定数字货币交易存在异常的情况下，第一终端应用向第一运营机构后台系统发送锁定请求，以由第一运营机构后台系统将锁定请求发送至第二运营机构后台系统，通过第二运营机构后台系统对第二终端应用和/或本次交易的数字货币币串进行锁定，第二运营机构后台系统为第二终端应用的运营机构后台。
在将数字货币交易信息发送到第一运营机构后台系统进行验证，并确定数字货币交易存在异常的情况下，第一终端应用根据数字货币交易信息更新本地双花信息列表。
双花信息包括用户钱包信息、数字货币信息、数字货币版本信息中的一种或多种信息，数字货币信息包括数字货币表达式和/或冠字号。
本公开实施例可实现在交易过程中对交易对手方进行核验(或称验证)，其中，当终端应用离线时根据本地双花信息进行核验，当终端应用在线时可采用本地双花信息核验或发送至运营机构后台进行核验，防止违法或异常钱包的重复花费或数字货币的重复花费，此外，可对违法或异常钱包进行锁定，禁止交易对手方继续交易，降低数字货币双花风险。并且，本公开实施例可通过多个维度进行双花验证， 例如，双花信息可包含用户钱包信息例如钱包ID、用户公钥等，以对用户进行判断；也可包含数字货币信息例如整个表达式或冠字号，以对数字货币进行判断；也可包含版本信息，对数字货币或钱包应用版本进行判断，达到从不同维度进行风险控制。同时终端应用可将异常上报运营机构后台，并更新本地双花信息列表，以减少存储压力。
图2是根据本公开另一个实施例的数字货币交易异常的验证方法的主要步骤示意图。如图2所示，包括如下的步骤S201至步骤S202。
步骤S201：第一运营机构后台系统接收第一终端应用发送的数字货币交易信息；
其中，第一运营机构后台系统为第一终端应用的运营机构后台，数字货币交易信息是第二终端应用发送到第一终端应用的。
步骤S202：第一运营机构后台系统利用双花信息列表对数字货币交易信息进行双花验证，如果双花验证不通过，则向第一终端应用返回指示数字货币交易存在异常的验证结果。
在一个实施例中，第一运营机构后台系统利用双花信息列表对数字货币交易信息进行双花验证，具体包括：第一运营机构后台系统在已存双花信息列表中查找数字货币交易信息对应的双花信息，如果查找到数字货币交易信息对应的双花信息，则双花验证不通过。
已存双花信息列表中的双花信息包括第一双花信息和第二双花信息，第一双花信息是第一运营机构后台系统基于自身签发的数字货币的版本信息、所签发数字货币对应的用户钱包信息和数字货币信息中的一种或多种信息的异常而生成的，第二双花信息是第一运营机构后台系统通过互联互通从其他运营机构后台系统同步得到的。
在一个实施例中，第一运营机构后台系统利用双花信息列表对数 字货币交易信息进行双花验证，具体包括：第一运营机构后台系统将数字货币交易信息发送至第一验证平台，由第一验证平台在自有的双花信息列表中查找数字货币交易信息对应的双花信息，第一验证平台为除第一运营机构后台系统之外的其他运营机构后台系统或由各运营机构共享的双花信息共享平台；如果查找到数字货币交易信息对应的双花信息，则双花验证不通过。
根据上述实施例，如果查找到对应的双花信息，则双花验证不通过，从而确定数字货币交易存在异常，而如果未查找到对应的双花信息，则双花验证通过，从而确定交易无异常。
在另一个实施例中，在上述实施例基础上，进一步包括：如果双花验证通过，则第一运营机构后台系统将数字货币交易信息发送至本次交易的数字货币的签发机构后台系统；由签发机构后台系统对数字货币交易信息所含的用户钱包信息、数字货币信息、数字货币版本信息中的一种或多种信息进行信息校验，如果信息校验不通过，则向第一终端应用返回指示数字货币交易存在异常的验证结果。即，在双花验证和信息校验都通过的情况下，才确定交易无异常，而双花验证和信息校验中任一者不通过，都会确定数字货币交易存在异常。
本公开实施例由数字货币签发机构维护该数字货币的具体交易信息，其他各运营机构通过互联互通平台发送该币串的相关交易信息至签发机构，签发机构判断该币串的双花情况。
在数字货币交易存在异常的情况下，第一运营机构后台系统向第二运营机构后台系统发送锁定请求，通过第二运营机构后台系统对第二终端应用和/或本次交易的数字货币币串进行锁定，第二运营机构后台系统为第二终端应用的运营机构后台。
锁定请求是第一运营机构后台系统生成的，或由第一终端应用发 送到第一运营机构后台系统的。
本公开实施例实现在交易过程中，交易双方进行合法性校验，如果发现该用户或该数字货币双花，将拒绝交易，并上传后台或对其应用进行锁定，并且可由第一终端应用或第一运营机构后台系统发起锁定，有效降低了重复双花的风险，保证数字货币的交易安全。
图3是根据本公开又一个实施例的数字货币交易异常的验证方法的主要步骤示意图。如图3所示，包括如下的步骤S301至步骤S302。
步骤S301：在第二运营机构后台系统与第二终端应用建立网络连接的情况下，当第二终端应用向第一终端应用发送当前交易的数字货币交易信息之前，第二运营机构后台系统发起对当前交易的数字货币交易信息的双花验证；
其中，第二运营机构后台系统为第二终端应用的运营机构后台。
步骤S302：第二运营机构后台系统在双花验证不通过的情况下，确定当前交易存在异常，并终止当前交易。
在一个实施例中，第二运营机构后台系统发起对当前交易的数字货币交易信息的双花验证，具体包括：第二运营机构后台系统通过第二验证平台的双花信息列表，对当前交易的数字货币交易信息进行双花验证，第二验证平台为除第二运营机构后台系统之外的其他运营机构后台系统或由各运营机构共享的双花信息共享平台；在双花信息列表中存在当前交易的数字货币交易信息对应的双花信息的情况下，双花验证不通过。如果存在该对应的双花信息，则双花验证通过。
在另一个实施例中，第二运营机构后台系统发起对当前交易的数字货币交易信息的双花验证，具体包括：第二运营机构后台系统将当前交易的数字货币交易信息发送至当前交易的数字货币的签发机构后 台系统，由签发机构后台系统对当前交易的数字货币交易信息所含的用户钱包信息、数字货币信息、数字货币版本信息中的一种或多种信息进行信息校验，在信息校验不通过的情况下，双花验证不通过。如果信息校验通过，则表示双花验证也通过。
在有一个实施例中，可以将上述实施例的两种情况结合，即可以先通过第二验证平台的双花信息列表，对当前交易的数字货币交易信息进行双花验证，即在双花信息列表中存在当前交易的数字货币交易信息对应的双花信息，如果查找到对应的双花信息，则直接确定交易存在异常，如果未查找到该对应的双花信息，则进一步将当前交易的数字货币交易信息发送至当前交易的数字货币的签发机构后台系统，由签发机构后台系统进行上述的信息校验，在未查找到该对应的双花信息且信息校验通过的情况下，才确定交易无异常，而查找到该对应的双花信息或信息校验不通过，都确定交易存在异常，即确定存在双花的情况。
第二运营机构后台系统通过将第二终端应用和/或当前交易的数字货币币串进行锁定，来终止当前交易。
本公开实施例在交易过程中，如果发现用户或数字货币双花，将拒绝交易，并上传后台或对其应用进行锁定，并且可由第二运营机构后台系统发起锁定，有效降低了重复双花的风险，保证数字货币的交易安全。
图4是根据本公开又一个实施例的数字货币交易异常的验证方法的主要步骤示意图。如图4所示，包括如下的步骤S401至步骤S403。
步骤S401：第二运营机构后台系统与第二终端应用建立网络连接；
步骤S402：第二运营机构后台系统对第二终端应用在离线状态下已发出的数字货币交易信息进行双花验证，已发出的数字货币交易信 息是第二终端应用发送到其他终端应用的；
步骤S403：第二运营机构后台系统在双花验证不通过的情况下，将第二终端应用锁定，第二终端应用离线状态为第二终端应用与第二运营机构后台系统未建立网络连接的状态。
第二运营机构后台系统对第二终端应用在离线状态下已发出的数字货币交易信息进行双花验证，具体可以包括：
第二运营机构后台系统通过第三验证平台的双花信息列表，对已发出的数字货币交易信息进行双花验证，第三验证平台为除第二运营机构后台系统之外的其他运营机构后台系统或由各运营机构共享的双花信息共享平台；在双花信息列表中存在已发出的数字货币交易信息对应的双花信息的情况下，双花验证不通过，若不存在该对应的双花信息，则双花验证通过。
本实施例适用于在第二终端应用与其他终端应用在离线情况下完成交易之后，当第二终端应用因各类业务(例如充值、新的交易等)与第二运营机构后台系统建立网络连接的场景，实现第二运营机构后台系统与第二终端应用建立网络连接后，第二运营机构后台系统可以主动对第二终端应用在离线状态下已发出的数字货币交易信息进行双花验证，并主动发起锁定第二终端应用，有效降低了重复双花的风险，保证数字货币的交易安全。
图5是根据本公开一个实施例的支付交易异常的验证流程示意图，如图5所示，流程包括：双花信息的生成与管理；双花信息的存储与获取；终端侧进行交易；进行交易信息验证，其中，如果终端应用在线(即终端应用与其运营机构后台建立了网络连接)，可在终端本地进行验证或通过终端联网进行验证，如果终端应用离线(即与其运营机构后台未建立网络连接)，则在终端本地进行验证；如果验证通过，则继续交易；如果验证不通过，则拒绝交易，其中，在终端本地验证不通过并拒绝交易后，终端应用可向运营机构后台上报异常信息；在 通过终端联网进行验证并拒绝交易后，运营机构后台可记录交易异常并将应用锁定。
下面具体对本公开实施例所涉及的双花信息生成与管理、双花信息存储及获取、双花验证、终端应用锁定分别做详细介绍。
双花信息的生成与管理，具体地，运营机构后台可通过自身签发的数字货币的系统版本信息、发现程序BUG(缺陷)、用户钱包异常等行为进行双花信息列表的生成，在进行跨机构(跨运营机构)交易信息收集时，各个运营机构将交易信息与数字货币信息通过互联互通发送至签发机构(签发机构是指负责签发数字货币的运营机构，或称签发机构后台系统)，交易信息可包括用户钱包信息、数字货币信息、数字货币版本信息中的一种或多种信息，数字货币信息可包括数字货币表达式和/或冠字号。签发机构根据各个交易节点信息进行判断，如果发现某节点超额，可将该节点用户或数字货币信息列为双花信息，并同步至双花信息管理模块，双花信息管理模块即双花信息共享平台，其中的双花信息是从各个运营机构后台系统同步过来的。各个运营机构可以采用中心化或区块链的方式共同维护用户或数字货币的双花信息，本公开一个实施例的跨机构维护双花信息列表的示意图如图6所示，图6以三个机构为例，机构的数量不构成对本公开实施例保护范围的限定。由签发数字货币的发行(或称运营)机构维护该数字货币的额度，如果发现该数字货币发生双花，则将双花所有者更新至双花信息列表(池)。各运营机构有各自的机构后台管理模块，机构后台管理模块用于运营机构同步其他各运营机构的双花信息，新增、删减或更新本运营机构的双花信息，并可定期或在约定条件下将本运营机构的双花信息同步至其他各个运营机构。当钱包或数字货币状态正常或注销后，各个运营机构同步更新双花信息至双花信息管理模块。当用户或数字货币注销、双花应用锁定时，可更新双花信息列表，以减少存储压力。运营机构后台系统还可获取最新的双花信息并同步至相应的终端应用(例如第一运营机构后台系统将双花信息列表同步给第 一终端应用)，以及对本运营机构签发的币串交易信息进行管理核验。当钱包用户(即终端应用)在线时，运营机构后台将向钱包用户推送当前的双花信息列表，该双花信息列表可包含如钱包ID、公钥信息、数字货币、货币标识、版本信息等。使得在后续交易过程中，交易双方进行双花信息列表校验，如果发现该用户或该数字货币双花，将拒绝交易。当收款方在线时，可通过运营机构后台校验，并通过指令对双花钱包应用进行锁定，使其无法继续后续交易，有效降低了重复双花的风险，保证数字货币的交易安全。
双花信息的存储及获取，具体地，终端用户可在以下情况进行双花信息的同步：一是终端用户联网时；二是终端用户进行联机业务时，例如开立、充值、提现、同步、注销、查询等操作；三是由交易对手方同步双花信息，交易对手方是指与当前终端应用进行交易的另一终端应用。终端用户可在终端应用本地的安全芯片内存储双花信息，本地存储双花信息有助于离线交易时的双花验证。
双花的验证，具体地，交易双方(即第一终端应用与第二终端应用)在交易过程中，对交易对手方进行双花信息验证，验证方式可以通过本地双花信息验证，也可通过通信模块将交易信息(即数字货币交易信息)发送至相应的运营机构后台系统进行验证，由运营机构后台返回验证结果。双花信息可包含以下信息：数字货币版本信息，其用于表示数字货币版本或钱包应用版本；用户信息，包括但不限于钱包ID(标识)、用户公钥、用户证书、钱包Token(令牌)等；数字货币信息，包括但不限于数字货币表达式、冠字号、数字货币标识等。如果验证通过，则交易继续，如验证失败，终止本次交易，并将交易对手方信息上报至本终端应用对应的运营机构后台系统。
应用锁定，特别地，当验证失败时，在用户联网的情况下终端应用可将异常上报至终端应用的运营机构后台，由运营机构后台生成应用锁定指令，对交易对手方的钱包应用(即终端应用)进行锁定操作， 禁止其继续进行交易，同时更新本地双花信息，以减少存储压力。
本公开实施例不受终端形态及通讯方式影响，可广泛应用于各个终端形态的硬件钱包，包括但不限于IC卡、手机终端、受理终端、物联网终端等，通讯方式包括但不限于NFC(近场通信)、蓝牙、WIFI、UWB(超宽带)、二维码等方式。可实现在交易过程中对问题钱包或数字货币进行拒收及上报管理，并进行应用锁定(例如通过付款方的运营机构后台来锁定付款方的终端应用，付款方的终端应用可以是第二终端应用，付款方的运营机构后台相应可以是第二运营机构后台系统)，极大提升了交易过程中的安全性，有效避免了恶意用户、程序BUG(缺陷)等系统性风险，保障数字货币的平稳运行，有助于数字货币硬件钱包的推广上线。

双花验证模块901，用于在第二运营机构后台系统与第二终端应用建立网络连接的情况下，当第二终端应用向第一终端应用发送当前交易的数字货币交易信息之前，发起对当前交易的数字货币交易信息的 双花验证，其中，第二运营机构后台系统为第二终端应用的运营机构后台；
交易异常终止模块902，用于第二运营机构后台系统在双花验证不通过的情况下，确定当前交易存在异常，并终止当前交易。
在一个实施例中，双花验证模块901具体用于：通过第二验证平台的双花信息列表，对当前交易的数字货币交易信息进行双花验证，第二验证平台为除第二运营机构后台系统之外的其他运营机构后台系统或由各运营机构共享的双花信息共享平台；在双花信息列表中存在当前交易的数字货币交易信息对应的双花信息的情况下，双花验证不通过。若未查找到双花信息，则双花验证通过，确定当前交易无异常，继续交易的后续操作。
在一个实施例中，双花验证模块901具体用于：将当前交易的数字货币交易信息发送至当前交易的数字货币的签发机构后台系统，由签发机构后台系统对当前交易的数字货币交易信息所含的用户钱包信息、数字货币信息、数字货币版本信息中的一种或多种信息进行信息校验，在信息校验不通过的情况下，双花验证不通过。若信息校验通过，则双花验证通过，确定当前交易无异常，继续交易的后续操作。
在一个实施例中，可以通过对上述两个实施例的双花验证模块901的功能结合，即双花验证模块901可以先通过第二验证平台的双花信息列表，对当前交易的数字货币交易信息进行双花验证，如果该双花验证通过，再进一步将当前交易的数字货币交易信息发送至当前交易的数字货币的签发机构后台系统进行进一步的信息校验，若信息校验也通过，则表示当前交易不存在异常，继续交易的后续操作。而若双花验证、信息校验二者中有一个不通过，则表示当前交易存在异常，从而终止当前交易。
交易异常终止模块902具体用于通过将第二终端应用和/或当前交 易的数字货币币串进行锁定，来终止当前交易。

网络连接建立模块1001，用于与第二终端应用建立网络连接；
双花信息验证模块1002，用于对第二终端应用在离线状态下已发出的数字货币交易信息进行双花验证，已发出的数字货币交易信息是第二终端应用发送到其他终端应用的；第二终端应用离线状态为第二终端应用与第二运营机构后台系统未建立网络连接的状态；
应用锁定模块1003，用于在双花验证不通过的情况下，将第二终端应用锁定。
双花信息验证模块1002具体可以用于：通过第三验证平台的双花信息列表，对已发出的数字货币交易信息进行双花验证，第三验证平台为除第二运营机构后台系统之外的其他运营机构后台系统或由各运营机构共享的双花信息共享平台；在双花信息列表中存在已发出的数字货币交易信息对应的双花信息的情况下，双花验证不通过。
