具体实施方式
以下结合附图对本申请的示范性实施例做出说明,其中包括本申请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,而不会背离本申请的范围和精神。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是根据本申请实施例的第一方面的应用于第一客户端的数字货币的支付方法的主要流程的示意图,如图1所示,该数字货币的支付方法具体可以包括的步骤如下:
步骤S101,向第一客户端对应的第一货币管理装置发送交易金额,以使所述第一货币管理装置判断所述交易金额是否大于用于支付的第一数字货币的可用余额。
数字货币是指可用于代替纸币进行多种流通操作的货币,例如使用该数据货币进行支付,实现数字货币持有者的转移,或者直接转让数字货币等。具体地,数字货币包括如下一种或多种信息:数字货币的流通标识、数字货币所属的数字货币管理装置标识、数字货币管理装置的签名。其中,数字货币的流通标识是指与数字货币对应的唯一流通标识(如冠字号),该流通标识可以为字符串,也可以为二维码等形式,以便于该数字货币的流通。
交易金额既可以是指第一客户端根据实际需要支付的金额生成的,也可以是指第一客户端接收的第二客户端生成的交易金额。因而,在向所述第一货币管理装置发送交易金额之前,第一客户端还需生成所述交易金额或接收所述第二客户端发送的所述交易金额。
第一数字货币的可用额度是指用于支付的第一数字货币当前可用户支付的最大金额。具体地,第一客户端在向第一货币管理装置发送交易金额之前,还需预先向所述第一货币管理装置发送数字货币导出请求,所述数字货币导出请求指示了所述第一数字货币的面额,以使所述第一货币管理装置生成所述第一数字货币并记录所述第一数字货币对应的可用余额为所述第一数字货币的面额。也即是说,第一数字货币的初始可用余额是指第一数字货币的面额,且随着支付交易的进行,第一数字货币的可用余额逐步减少。
在此基础上,第一货币管理装置在接收到第一客户端发送的交易金额后,判断交易金额是否大于第一数字货币的可用余额,若不大于,则表明可用余额足以覆盖交易金额,可以正常使用第一数字货币进行交易;若大于,则表明可用余额不足以覆盖交易金额,无法使用第一数字货币继续正常的支付交易。如此通过判断交易金额与可用余额的大小,可以对能够正常进行交易对的金额进行管控,避免了第一客户端用户通过透支账户余额进行非法交易等,进一步提高了数字货币交易过程中的安全可靠性。
步骤S102,在所述交易金额不大于所述可用余额的情况下,向第二客户端发送支付请求,所述支付请求指示了所述第一数字货币或所述第一数字货币的流通标识,以使所述第二客户端对应的第二货币管理装置向所述第一货币管理装置兑付与所述交易金额对应的第二数字货币。
具体地,第二客户端在接收到第一客户端发送的支付请求后,向第二货币管理装置发送数字货币兑付请求,该数字货币兑付请求指示了交易金额、第一数字货币或第一数字货币的标识。基于此,第二货币管理装置向第一货币管理装置发送第一数字货币或第一数字货币的流通标识,以使第一货币管理装置对第一数字货币或第一数字货币的流通标识进行验证,并在第一数字货币或第一数字货币的流通标识的验证通过的情况下,生成与交易金额对应的第二数字货币,从而实现了数字货币在第一客户端与第二客户端之间的流转。
可以理解的是,第二货币管理装置在生成第二数字货币后,应更新第二客户端对应的数字货币记录,是对数字货币进行管理。
与此相对应,在所述第二货币管理装置兑付完所述第二数字货币的情况下,所述第一货币管理装置更新所述第一数字货币的可用余额,且更新后的所述可用余额指示了更新前所述可用余额与所述交易金额的差值。如此,保证了数字货币支付过程中,数字货币总额度的平衡。
值得一提的是,第一客户端与第二客户端对应的货币管理装置即可能相同也可能不相同,为实现对不同货币管理装置之间货币流通的监管,避免不同货币管理之间非法交易,以进一步保证数字货币的合法性及安全性,在第一货币管理装置不同于第二货币管理装置的情况下,第二货币管理装置通过对不同货币管理装置进行监管的第三方货币管理装置,将第一数字货币或所述流通标识发送至第一货币管理装 置。同时,在第一货币管理装置在对第一数字货币或第一数字货币的流通标识进行验证后,第一货币管理装置也通过第三方货币管理装置将对应的验证结果发送至第二货币管理装置。
此外,为进一步提高数字货币支付过程中的安全性,第一客户端可以对第一数字货币或第一数字货币对应的流通标识进行加密,也即设置支付密码。当且仅当第二客户端在获取到正确的支付密码的情况下,才能正常的完成数字货币的支付交易,以避免非法客户端进行非法交易。具体地,可使用的加密方式包括但不限于字符串加密方式(字母、数字或字母与数字组合的字符串加密方式)、问答方式、声纹识别方式、人脸识别方式、图片识别方式中的任意一种或多种方式的组合。
基于上述实施例,通过第一客户端对应的第一货币管理装置维护用于支付的第一数字货币的可用余额,并通过判断可用余额与交易金额的大小,使得当且仅当交易金额不大于可用余额的情况下才能正常进行支付交易,实现了对交易金额的管控,避免了第一客户端用户透支账户以进行非法交易,保证了数字货币交易过程中的安全性、可靠性。
参见图2,在上述与图1相关的实施例的基础上本申请实施例提供了一种应用于第一客户端的数字货币的支付方法,该方法具体可以包括的步骤如下:
步骤S201,向第一客户端对应的第一货币管理装置发送数字货币导出请求,所述数字货币导出请求指示了第一数字货币的面额,以使所述第一货币管理装置生成所述第一数字货币并记录所述第一数字货币对应的可用余额为所述第一数字货币的面额。
步骤S202,生成所述交易金额或接收所述第二客户端发送的所述交易金额。
步骤S203,向第一货币管理装置发送交易金额,以使所述第一货币管理装置判断所述交易金额是否大于用于支付的第一数字货币的可用余额。
步骤S204,在所述交易金额不大于所述可用余额的情况下,向第二客户端发送支付请求,所述支付请求指示了所述第一数字货币或所述第一数字货币的流通标识,以使所述第二客户端对应的第二货币管理装置向所述第一货币管理装置兑付与所述交易金额对应的第二数字货币。
参见图3,在对应于上述图1或图2所示的实施例,本申请实施例提供了一种应用于第一货币管理装置的数字货币的支付方法,该方法具体可以包括的步骤如下:
步骤S301,接收第一客户端发送的交易金额。
交易金额既可以是指第一客户端根据实际需要支付的金额生成的,也可以是指第一客户端接收的第二客户端生成的交易金额。因而,在向所述第一货币管理装置发送交易金额之前,第一客户端还需生成所述交易金额或接收所述第二客户端发送的所述交易金额。
步骤S302,判断所述交易金额是否大于用于支付的第一数字货币的可用余额。
可以理解的是,在接收第一客户端发送的交易金额之前,第一货币管理装置还接收第一客户端发送的数字货币导出请求,所述数字货币导出请求指示了所述第一数字货币的面额;根据所述数字货币导出请求生成所述第一数字货币,并记录所述第一数字货币对应的可用余额为所述第一数字货币的面额。也即是说,第一数字货币的初始可用余额是指第一数字货币的面额,且随着支付交易的进行,第一数字货 币的可用余额逐步减少。
具体地,以第一数字货币的可用余额为100为例进行说明,若交易金额为50,则表明可用余额100足以覆盖交易金额50,可以正常使用第一数字货币进行交易;若交易金额为150,则表明可用余额100不足以覆盖交易金额150,无法使用第一数字货币继续正常的支付交易。如此通过判断交易金额与可用余额的大小,可以对能够正常进行交易对的金额进行管控,避免了第一客户端用户通过透支账户余额进行非法交易等,进一步提高了数字货币交易过程中的安全可靠性。
步骤S303,在所述交易金额不大于所述可用余额的情况下,通知所述第一客户端向第二客户端发送支付请求,所述支付请求指示了所述第一数字货币或所述第一数字货币的流通标识。

在此基础上,第一货币管理装置在接收到所述第二客户端对应的第二货币管理装置发送的所述第一数字货币或所述流通标识的情况下,对所述第一数字货币或所述流通标识进行如下验证:判断该第一数字货币或流通标识是否为已记录或已存储的第一数字货币,以验证该数字货币来源的合法性;或根据第一数字货币指示的货币管理装置的标识,判断该货币管理装置的标识与第一货币管理装置标识是否一致,验证该数字货币来源的合法性;又或根据第一数字货币包括的货币管理装置的签名进行验证,如以货币管理装置的签名是使用非对称加密算法生成的为例进行说明,则第一货币管理装置可以使用生成签名信 息时的公钥对应的私钥对第一数字货币中的货币管理装置的签名进行解密以验证该签名信息的可靠性。如此,既可以保证第一数字货币来源的合法性,又可以保证数字货币兑付的安全性。
在所述第一数字货币或所述流通标识进行验证通过的情况下,更新所述第一数字货币的可用余额,且更新后的所述可用余额指示了更新前所述可用余额与所述交易金额的差值。如,更新前可用余额为100,交易金额为40,则更新后可用余额为60。
同时,第一货币管理装置将所述第一数字货币或所述流通标识的验证结果发送至所述第二货币管理装置,使得第二货币管理装置在第一数字货币或第一数字货币的流通标识的验证通过的情况下,生成与交易金额对应的第二数字货币,从而实现了数字货币在第一客户端与第二客户端之间的流转。

步骤S1218,在所述第一数字货币或所述第一数字货币的流通标识的验证通过的情况下,第一货币管理装置更新所述第一数字货币的可用余额,且更新后的所述可用余额指示了更新前的可用余额与所述交易金额的差值。
图13是根据本申请的第二方面提供的实施例的应用于第一客户端的数字货币的支付方法的主要流程的示意图,如图13所示,该数字货币支付方法具体可以包括的步骤如下:
步骤S1301,向第一客户端对应的第一货币管理装置发送交易金额,以使所述第一货币管理装置在所述交易金额小于用于支付的第一数字 货币的面额的情况下,将所述第一数字货币拆分为第三数字货币、第四数字货币;其中,所述第三数字货币的面额指示了所述交易金额,所述第四数字货币的面额指示了所述第一数字货币的面额与所述交易金额的差值。
数字货币、数字货币的流通标识、交易金额在上述图1所示的实施例中已经陈述,在此不再赘述。
在向所述第一货币管理装置发送交易金额之前,第一客户端还需生成所述交易金额或接收所述第二客户端发送的所述交易金额。
在进行支付交易的过程中,交易金额既可能大于第一数字货币的面额,也可能小于第一数字货币的面额,当且仅当交易金额不大于第一数字货币的面额的情况下,才能使用第一数字货币进行正常的交易。具体地,以第一数字货币的面额为100、交易金额为40为例进行说明,为完成支付,根据交易金额的大小将第一数字货币(面额100)拆分为面额与交易金额相等的第三数字货币(面额40)、第四数字货币(面额60),然后可使用与交易金额对应的第三数字货币(面额40)直接进行支付,实现了数字货币支付过程中的兑付及找零。可以理解的是,在交易金额与第一数字货币的面额相等的情况下,则无需进行拆分,可直接使用第一数字货币进行支付。
可以理解的是,第一客户端在向第一货币管理装置发送交易金额之前,还需预先向所述第一货币管理装置发送数字货币导出请求,所述数字货币导出请求指示了所述第一数字货币的面额,以使所述第一货币管理装置生成所述第一数字货币并记录所述第一数字货币为用于支付的数字货币。也即是说,新生成的第一数字货币即为用于支付的数字货币,但随着支付交易的进行第一数字货币被拆分为第三数字货币、第四数字货币,则用于支付的数字货币不断变更,对应的面额也不断减少。
步骤S1302,接收所述第一货币管理装置下发的所述第三数字货币。也即是说,为方便快捷的完成数字货币的支付,在第一货币管理装置将第一数字货币拆分为第三数字货币、第四数字货币之后,仅将与交易金额相对应的第三数字货币下发至第一客户端,以供第一客户端使用第一数字货币进行支付交易。
步骤S1303,向第二客户端发送支付请求,所述支付请求指示了所述第三数字货币或所述第三数字货币的流通标识,以使所述第二客户端对应的第二货币管理装置向所述第一货币管理装置兑付与所述第三数字货币对应的第五数字货币。
具体地,第二客户端在接收到第一客户端发送的支付请求后,向第二货币管理装置发送数字货币兑付请求,该数字货币兑付请求指示了第三数字货币或第三数字货币的流通标识。基于此,第二货币管理装置向第一货币管理装置发送第三数字货币或第三数字货币的流通标识,以使第一货币管理装置对第三数字货币或第三数字货币的流通标识进行验证,并在第一数字货币或第一数字货币的流通标识的验证通过的情况下,生成与交易金额或第三数字货币对应的第五数字货币,从而实现了数字货币在第一客户端与第二客户端之间的流转。
可以理解的是,第二货币管理装置在生成第五数字货币后,应更新第二客户端对应的数字货币记录,是对数字货币进行管理。
与此相对应,在所述第二货币管理装置兑付完所述第五数字货币的情况下,所述第一货币管理装置将用于支付的数字货币更新为拆分后得到的第四数字货币,且该第四数字货币的面额指示了第一数字货币的面额与交易金额的差值。如此,保证了数字货币支付过程中,数字货币总额度的平衡。
值得一提的是,第一客户端与第二客户端对应的货币管理装置即可能相同也可能不相同,为实现对不同货币管理装置之间货币流通的监管,避免不同货币管理之间非法交易,以进一步保证数字货币的合法性及安全性,在第一货币管理装置不同于第二货币管理装置的情况下,第二货币管理装置通过对不同货币管理装置进行监管的第三方货币管理装置,将第三数字货币或第三数字货币的流通标识发送至第一货币管理装置。同时,在第一货币管理装置在对第三数字货币或第三数字货币的流通标识进行验证后,第一货币管理装置也通过第三方货币管理装置将对应的验证结果发送至第二货币管理装置。
此外,为进一步提高数字货币支付过程中的安全性,第一客户端可以对第三数字货币或第三数字货币对应的流通标识进行加密,也即设置支付密码。当且仅当第二客户端在获取到正确的支付密码的情况下,才能正常的完成数字货币的支付交易,以避免非法客户端进行非法交易。具体地,可使用的加密方式包括但不限于字符串加密方式(字母、数字或字母与数字组合的字符串加密方式)、问答方式、声纹识别方式、人脸识别方式、图片识别方式中的任意一种或多种方式的组合。
基于上述实施例,通过第一客户端对应的第一货币管理装置判断交易金额是否小于用于支付的第一数字货币的面额,并在交易金额小于第一数字货币的面额的情况下,将第一数字货币拆分为第四数字货币、与交易金额对应的第三数字货币,并通过使用第三数字货币进行支付,实现了数字货币支付过程中数字货币的兑付、找零,提高了数字货币支付过程中的安全性、便捷性。
参见图14,在上述与图13相关的实施例的基础上,本申请实施例提供了另一个应用于第一客户端的数字货币的支付方法,该方法具体可以包括的步骤如下:
步骤S1401,向所述第一货币管理装置发送数字货币导出请求,所 述数字货币导出请求指示了所述第一数字货币的面额,以使所述第一货币管理装置生成所述第一数字货币并记录所述第一数字货币为用于支付的数字货币。
步骤S1402,生成交易金额或接收第二客户端发送的所述交易金额。
步骤S1403,向第一客户端对应的第一货币管理装置发送交易金额,以使所述第一货币管理装置在所述交易金额小于用于支付的第一数字货币的面额的情况下,将所述第一数字货币拆分为第三数字货币、第四数字货币;其中,所述第三数字货币的面额指示了所述交易金额,所述第四数字货币的面额指示了所述第一数字货币的面额与所述交易金额的差值。
步骤S1404,接收所述第一货币管理装置下发的所述第三数字货币。
步骤S1405,向第二客户端发送支付请求,所述支付请求指示了所述第三数字货币或所述第三数字货币的流通标识,以使所述第二客户端对应的第二货币管理装置向所述第一货币管理装置兑付与所述第三数字货币对应的第五数字货币。

步骤S1501,接收与第一货币管理装置对应的第一客户端发送的交易金额。
交易金额既可以是指第一客户端根据实际需要支付的金额生成的,也可以是指第一客户端接收的第二客户端生成的交易金额。因而,在向所述第一货币管理装置发送交易金额之前,第一客户端还需生成所述交易金额或接收所述第二客户端发送的所述交易金额。
步骤S1502,判断所述交易金额是否小于用于支付的第一数字货币的面额。
在进行支付交易的过程中,交易金额既可能大于第一数字货币的面额,也可能小于第一数字货币的面额,当且仅当交易金额不大于第一数字货币的面额的情况下,才能使用第一数字货币进行正常的交易。
步骤S1503,在所述交易金额小于所述第一数字货币的面额的情况下,将所述第一数字货币拆分为第三数字货币、第四数字货币;其中,所述第三数字货币的面额指示了所述交易金额,所述第四数字货币的面额指示了所述第一数字货币的面额与所述交易金额的差值。
具体地,以第一数字货币的面额为100、交易金额为40为例进行说明,为完成支付,根据交易金额的大小将第一数字货币(面额100)拆分为面额与交易金额相等的第三数字货币(面额40)、第四数字货币(面额60),然后可使用与交易金额对应的第三数字货币(面额40)直接进行支付,实现了数字货币支付过程中的兑付及找零。可以理解的是,在交易金额与第一数字货币的面额相等的情况下,则无需进行拆分,可直接使用第一数字货币进行支付。
步骤S1504,将所述第三数字货币下发至所述第一客户端,以使所述第一客户端使用所述第三数字货币进行支付。
在此基础上,第一客户端向第二客户端发送支付请求,支付请求指示了第三数字货币或第三数字货币的流通标识。第二客户端在接收到第一客户端发送的支付请求后,向第二货币管理装置发送数字货币兑付请求,该数字货币兑付请求指示了第三数字货币或第三数字货币的流通标识。基于此,第二货币管理装置向第一货币管理装置发送第一数字货币或第一数字货币的流通标识,以使第一货币管理装置对第 三数字货币或第三数字货币的流通标识进行验证。
更进一步地,第一货币管理装置在接收到所述第二客户端对应的第二货币管理装置发送的第三数字货币或第三数字货币的流通标识的情况下,对第三数字货币或第三数字货币的流通标识进行如下验证:判断该第三数字货币或流通标识是否为已记录或已存储的第三数字货币,以验证该数字货币来源的合法性;或根据第三数字货币指示的货币管理装置的标识,判断该货币管理装置的标识与第一货币管理装置标识是否一致,验证该数字货币来源的合法性;又或根据第三数字货币包括的货币管理装置的签名进行验证,如以货币管理装置的签名是使用非对称加密算法生成的为例进行说明,则第一货币管理装置可以使用生成签名信息时的公钥对应的私钥对第三数字货币中的货币管理装置的签名进行解密以验证该签名信息的可靠性。如此,既可以保证第三数字货币来源的合法性,又可以保证数字货币兑付的安全性。
在所述第三数字货币或所述流通标识进行验证通过的情况下,第一货币管理装置将用于支付的数字货币更新为所述第四数字货币。
同时,第一货币管理装置将所述第三数字货币或所述流通标识的验证结果发送至所述第二货币管理装置,使得第二货币管理装置在第三数字货币或第三数字货币的流通标识的验证通过的情况下,生成与第三数字货币对应的第五数字货币,从而实现了数字货币在第一客户端与第二客户端之间的流转。

图24是根据本申请实施例的应用于第二客户端的数字货币的支付方法的主要流程的示意图,如图24所示,该数字货币的支付方法,具体可以包括的步骤如下:
步骤S2401,获取第一客户端提供的二维码,所述二维码指示了用于支付的第一数字货币或所述第一数字货币对应的流通标识。
数字货币是指可用于代替纸币进行多种流通操作的货币,例如使用该数据货币进行支付,实现数字货币持有者的转移,或者直接转让数字货币等。具体地,数字货币包括如下一种或多种信息:数字货币的流通标识、数字货币所属的数字货币管理装置标识、数字货币管理 装置的签名。其中,数字货币的流通标识是指与数字货币对应的唯一流通标识(如冠字号),该流通标识可以为字符串,也可以为二维码等形式,以便于该数字货币的流通。
二维码是第一客户端或第一货币管理装置根据第一数字货币或第一数字货币的流通标识生成的。解析后的二维码包括如一种或多种信息:第一数字货币、第一数字货币的流通标识、第一货币管理装置标识、第一数字货币的使用场景。二维码可以以多种形式存在,如直接存储于用户移动终端(如手机、IPAD等)、可穿戴设备,或直接以图片形式存在,或者打印文件等。如此,用户在通过第一客户端向第二客户端提供二维码时,既可以直接通过彼此之间的通信连接发送二维码,也可以直接展示二维码以供第二客户端使用扫描枪或智能终端扫描该二维码,以获取二维码指示的数字货币信息等。也即是说,即使第一客户端处理离线状态,仍然可以通过提供承载有数字货币的二维码完成支付交易。
更进一步地,为防止其他非法终端在获取到二维码的情况下,冒充第二客户端与第一客户端进行支付交易等,可以使用与二维码加密方式对应的第一密钥对二维码进行加密。使用的加密方式可以为字符串加密方式(字母、数字或字母与数字组合的字符串加密方式)、问答方式、声纹识别方式、人脸识别方式、图片识别方式中的任意一种或多种方式的组合,而不同加密方式所对应的密钥有所不同。如此,当前仅当在获取到二维码以及对应的第一密钥的情况下才能正常根据二维码进行交易。具体地,在二维码为加密的二维码的情况下,第二客户端在向第二客户端对应的第二货币管理装置发送数字货币兑付请求之前,需向第一客户端获取与二维码加密方式对应的第一密钥,并使用所述第一密钥解密所述二维码,以从二维码中获取数字货币信息。
除此之外,为进步保证数字货币的支付安全性,第一客户端的用户根据与第一数字货币的面额对应的加密方式,对第一数字货币或第 一数字货币对应的流通标识进行加密。同时,第一客户端对应的第一货币管理装置预先记录第一数字货币、第一数字货币的流通标识、第一数字货币的面额对应的加密方式、加密方式对应的第二密钥等,以对数字货币进行管理。
基于此,在二维码指示的第一数字货币为加密的第一数字货币的情况下,或在二维码指示的流通标识为加密的流通标识的情况下,第二客户端还需根据第一数字货币的面额对应的加密方式获取对应的第二密钥,以在向第二客户端对应的第二货币管理装置发送数字货币兑付请求时,将第二密钥增添至数字货币兑付请求中,也即数字货币兑付请求指示了二维码,或解析二维码后获取的第一数字货币或所述流通标识,以及第二密钥。也即是说,为兼顾使用数字货币支付的安全性及便捷性,可以根据交易金额大小设置不同的加密方式,如当交易金额大于设定阈值时,采用声纹识别、面部识别等生物特征类型的密码对数字货币的支付进行验证;而在交易金额小于设定阈值时,采用字母加密方式、数字加密方式对应的密钥对数字货币的支付进行验证。
具体地,使用的加密方式可以为字符串加密方式(字母、数字或字母与数字组合的字符串加密方式)、问答方式、声纹识别方式、人脸识别方式、图片识别方式中的任意一种或多种方式的组合。不同加密方式所对应的密钥有所不同,例如,字符串加密方式所对应的密钥即为全为字母的字符串(字母加密方式)、或者全为数字的字符串(数字加密方式)或者同时包含字母与数字的字符串(字母与数字组合的加密方式),问答方式所对应的密钥为一对或多对问题和答案的组合,声纹识别方式所对应的密钥为可表征用户声纹的音频或其他格式的文件(如通过声纹识别模型提取出的特征值),人脸识别方式所对应的密钥为可表征用户人脸特征的图像或其他格式的文件(如通过人脸识别模型提取出的特征值)、图片识别方式所对应的密钥为用户选定的一张或多张图像。此外,第一客户端对应的用户可自定义加密方式,或第一货币管理装置也可根据便于管理或自身运营情况等因素来定义 加密方式。
步骤S2402,向第二客户端对应的第二货币管理装置发送数字货币兑付请求,所述数字货币兑付请求指示了所述二维码,或解析所述二维码后获取的所述第一数字货币或所述流通标识,以使所述第二货币管理装置向所述第一客户端对应的第一货币管理装置兑付与所述第一数字货币对应的第二数字货币。
可以理解的是,第二客户端在获取到承载有第一数字货币或第一数字货币的流通标识后,既可以直接对二维码进行解析以获取二维码指示的第一数字货币或流通标识,也可以直接将二维码发送至第二货币管理装置以使第二货币管理装置对二维码进行解析以获取第一数字货币或流通标识。
在此基础上,第二货币管理装置将第一数字货币或流通标识发送至第一客户端对应的第一货币管理装置,以使第一货币管理装置对第一数字货币或流通标识进行验证。第一货币管理装置在接收到第二货币管理装置发送的第一数字货币或流通标识后,可以根据第一客户端对应的数字货币记录,对其进行如下验证:判断该第一数字货币或流通标识是否为已记录或已存储的第一数字货币,以验证该数字货币来源的合法性;或根据第一数字货币指示的货币管理装置的标识,判断该货币管理装置的标识与第一货币管理装置标识是否一致,验证该数字货币来源的合法性;又或根据第一数字货币包括的货币管理装置的签名进行验证,如以货币管理装置的签名是使用非对称加密算法生成的为例进行说明,则第一货币管理装置可以使用生成签名信息时的公钥对应的私钥对第一数字货币中的货币管理装置的签名进行解密以验证该签名信息的可靠性。如此,既可以保证第一数字货币来源的合法性,又可以保证数字货币兑付的安全性。
在第一数字货币或流通标识验证通过的情况下,也即确认第一数 字货币合法的情况下,更新第一货币管理装置对应的数字货币记录,如将第一数字货币状态记录为不可用或注销第一数字货币以停止第一数字货币的流通,更新第一客户端对应的可用数字货币余额等。
与此相对应,第二货币管理装置在接收到第一货币管理装置验证第一数字货币或流通标识通过的情况下,生成与第一数字货币对应的第二数字货币,且该第二数字货币的面额应与第一数字货币的面额一致。同时,更新第二客户端对应的数字货币记录,如增加新生成的第二数字货币,将第二数字货币状态记录为可导状态。
值得注意的是,处于导出状态的数字货币即为可流通状态,也就是说,货币管理装置将处于导出状态的数字货币通知给响应的客户端后,客户端的用户可对该数字货币进行多种流通操作,例如利用该数字货币进行支付,实现数字货币持有者的转移,或直接将该数字货币转让,数字货币的受让者可利用受让的数字货币再进行支付或再次转让等。换句话说,处于导出状态的数字货币在一定程度上相当于传统纸币,其持有者即拥有使用权限。
在此基础上,在生成第二数字货币之后,第二货币管理装置可选择性将第二数字货币或第二数字货币对应的流通标识通知给第二客户端。因而第二客户端可选择性的接收第二货币管理装置下发的第二数字货币或第二数字货币对应的流通标识。
更进一步地,在二维码指示的第一数字货币为加密的第一数字货币的情况下,或在二维码指示的流通标识为加密的流通标识的情况下,第二客户端向第二货币管理装置发送的数字货币兑付请求还指示了第二客户端从第一客户端获取的与第一数字货币的面额对应的加密方式对应的第二密钥,以使第二货币管理装置将第一数字货币或流通标识,以及第二密钥发送至第一货币管理装置,以使第一货币管理装置对第一数字货币或流通标识,以及第二密钥进行验证。具体地,第一货币 管理装置在接收到第二密钥后根据与第一客户端对应的数字货币记录,判断第二密钥与记录的第一货币的面额对应的加密方式对应的密钥是否一致,以判断第二密钥的合法性。当且仅当第一数字货币标识或流通标识,以及第二密钥均验证通过的情况下,第一货币管理装置才更新第一客户端对应的数字货币记录,第二货币管理装置才生成与第一数字货币对应的第二数字货币。
值得一提的是,第一客户端与第二客户端对应的货币管理装置即可能相同也可能不相同,为实现对不同货币管理装置之间货币流通的监管,避免不同货币管理之间非法交易,以进一步保证数字货币的合法性及安全性,在第一货币管理装置不同于第二货币管理装置的情况下,第二货币管理装置通过对不同货币管理装置进行监管的第三方货币管理装置,将第一数字货币或所述流通标识发送至第一货币管理装置。同时,在第一货币管理装置在对第一数字货币或第一数字货币的流通标识进行验证后,第一货币管理装置也通过第三方货币管理装置将对应的验证结果发送至第二货币管理装置。
基于上述实施例,使用二维码承载数字货币或数字货币的流通标识,并使用二维码进行数字货币的支付,则进行支付交易的第一客户端与第二客户端无需保持通信连接,即使第一客户端处于离线状态,也可以通过预先存储的二维码图片或者文件等向第二客户端展示二维码,从而继续正常进行数字货币支付,提高了数字货币支付的便捷性。此外,通过对二维码进行加密,和/或对二维码指示的数字货币或数字货币的流通标识进行加密,进一步提高了数字货币支付过程中的安全性。

图37是根据本申请实施例的应用于第二客户端的数字货币的支付方法的主要流程的示意图,如图37所示,该数字货币的支付方法具体 可以包括的步骤如下:
步骤S3701,接收第一客户端发送的支付请求,所述支付请求指示了用于支付的第一数字货币或所述第一数字货币对应的流通标识。
数字货币是指可用于代替纸币进行多种流通操作的货币,例如使用该数字货币进行支付,实现数字货币持有者的转移,或者直接转让数字货币等。具体地,数字货币包括如下一种或多种信息:数字货币的流通标识、数字货币所属的数字货币管理装置标识、数字货币管理装置的签名。其中,数字货币的流通标识是指与数字货币对应的唯一流通标识(如冠字号),该流通标识可以为字符串,也可以为二维码等形式,以便于该数字货币的流通。
步骤S3702,根据所述第一数字货币或所述流通标识,向第二客户端对应的第二货币管理装置发送数字货币兑付请求,以使所述第二货币管理装置向所述第一客户端对应的第一货币管理装置兑付与所述第一数字货币对应的第二数字货币。如此,第二货币管理装置可以基于第一数字货币或流通标识,将第一数字货币兑付成归属于第二客户端的第二数字货币,从而实现数字货币在不同客户端之间的转移以完成支付等交易。
具体地,所述第二货币管理装置向所述第一客户端对应的第一货币管理装置兑付与所述第一数字货币对应的第二数字货币包括:将所述第一数字货币或所述流通标识发送给所述第一货币管理装置,以使所述第一货币管理装置对所述第一数字货币或所述流通标识进行验证;在所述第一数字货币或所述流通标识验证通过的情况下,生成与所述第一数字货币对应的第二数字货币,并更新所述第二客户端对应的数字货币记录。
可以理解的是,货币管理装置会记录并存储由该货币管理装置导出或生成的数字货币和\或对应的流通标识,以便对数字货币进行统一 管理。因此,在第一货币管理装置接收到第二货币管理装置发送的第一数字货币或流通标识后,可以对其进行如下验证:判断该第一数字货币或流通标识是否为已记录或已存储的第一数字货币,以验证该数字货币来源的合法性;或根据第一数字货币指示的货币管理装置的标识,判断该货币管理装置的标识与第一货币管理装置标识是否一致,验证该数字货币来源的合法性;又或根据第一数字货币包括的货币管理装置的签名进行验证,如以货币管理装置的签名是使用非对称加密算法生成的为例进行说明,则第一货币管理装置可以使用生成签名信息时的公钥对应的私钥对第一数字货币中的货币管理装置的签名进行解密以验证该签名信息的可靠性。如此,既可以保证第一数字货币来源的合法性,又可以保证数字货币兑付的安全性。
在第一数字货币或流通标识验证通过的情况下,也即确认第一数字货币合法的情况下,更新第一货币管理装置对应的数字货币记录,如将第一数字货币状态记录为不可用或注销第一数字货币以停止第一数字货币的流通,更新第一客户端对应的可用数字货币余额等。
与此相对应,第二货币管理装置在接收到第一货币管理装置验证第一数字货币或流通标识通过的情况下,生成与第一数字货币对应的第二数字货币,且该第二数字货币的面额应与第一数字货币的面额一致。同时,更新第二客户端对应的数字货币记录,如增加新生成的第二数字货币,将第二数字货币状态记录为可导状态。
值得注意的是,处于导出状态的数字货币即为可流通状态,也就是说,货币管理装置将处于导出状态的数字货币通知给相应的客户端后,客户端的用户可对该数字货币进行多种流通操作,例如利用该数字货币进行支付,实现数字货币持有者的转移,或直接将该数字货币转让,数字货币的受让者可利用受让的数字货币再进行支付或再次转让等。换句话说,处于导出状态的数字货币在一定程度上相当于传统纸币,其持有者即拥有使用权限。
在此基础上,在生成第二数字货币之后,第二货币管理装置可选择性将第二数字货币或第二数字货币对应的流通标识通知给第二客户端。因而第二客户端可选择性的接收第二货币管理装置下发的第二数字货币或第二数字货币对应的流通标识。
值得一提的是,第一客户端与第二客户端对应的货币管理装置即可能相同也可能不相同,为实现对不同货币管理装置之间货币流通的监管,避免不同货币管理之间非法交易,以进一步保证数字货币的合法性及安全性,在第一货币管理装置不同于第二货币管理装置的情况下,第二货币管理装置通过对不同货币管理装置进行监管的第三方货币管理装置,将第一数字货币或所述流通标识发送至第一货币管理装置。同时,在第一货币管理装置在对第一数字货币或第一数字货币的流通标识进行验证后,第一货币管理装置也通过第三方货币管理装置将对应的验证结果发送至第二货币管理装置。
此外,为进一步保证数字货币的安全性,第一客户端的用户可在使用第一数字货币或第一数字货币对应的流通标识进行支付时,将第一数字货币或流通标识进行加密,也即为第一数字货币或流通标识设置支付密码,以使得第二客户端仅在能够获取到正确的支付密码的情况下,才能继续正常完成支付。具体地,使用的加密方式可以为字符串加密方式(字母、数字或字母与数字组合的字符串加密方式)、问答方式、声纹识别方式、人脸识别方式、图片识别方式中的任意一种或多种方式的组合。不同加密方式所对应的密钥有所不同,例如,字符串加密方式所对应的密钥即为全为字母的字符串(字母加密方式)、或者全为数字的字符串(数字加密方式)或者同时包含字母与数字的字符串(字母与数字组合的加密方式),问答方式所对应的密钥为一对或多对问题和答案的组合,声纹识别方式所对应的密钥为可表征用户声纹的音频或其他格式的文件(如通过声纹识别模型提取出的特征值),人脸识别方式所对应的密钥为可表征用户人脸特征的图像或其 他格式的文件(如通过人脸识别模型提取出的特征值)、图片识别方式所对应的密钥为用户选定的一张或多张图像。此外,第一客户端对应的用户可自定义加密方式,或第一货币管理装置也可根据便于管理或自身运营情况等因素来定义加密方式。
基于此,在所述第一数字货币或所述流通标识为加密的第一数字货币或流通标识的情况下,根据所述第一数字货币的面额对应的加密方式获取与所述加密方式对应的密钥;向第二客户端对应的第二货币管理装置发送数字货币兑换请求,所述数字货币兑付请求指示了所述第一数字货币或所述流通标识及所述加密方式对应的密钥。
也即是说,为兼顾使用数字货币支付的安全性及便捷性,可以根据交易金额大小设置不同的加密方式,如当交易金额大于设定阈值时,采用声纹识别、面部识别等生物特征类型的密码对数字货币的支付进行验证;而在交易金额小于设定阈值时,采用字母加密方式、数字加密方式对应的密钥对数字货币的支付进行验证。
具体地,第一货币装置中预先存储有不同的交易金额对应的加密方式,以及加密方式对应的密钥。在第二客户端接收到第一客户端的支付请求时,第二客户端的用户可直接输入第一客户端的用户告知的支付密码,也可以直接让第一客户端的用户输入声纹音频等支付密码,并在第二客户端将支付密码添加到数字货币兑付请求中发送至第二货币管理装置,使得第二货币管理装置将第一数字货币或流通标识,及支付密码发送给第一货币管理装置。基于此,第一货币管理装置在接收到第二货币管理装置发送的第一数字货币或流通标识及支付密码时,根据预先存储的交易金额对应的支付密码对接收到的支付密码进行验证,以确保第一客户端的用户身份的合法性,以进一步保证数字货币的支付安全性。
基于上述实施例提供的数字货币的支付方法,在实际的交易过程 中,第一客户端可以直接向第二客户端发起支付请求,该支付请求指示了用于支付的第一数字货币或第一数字货币对应的流通标识,从而使得第二客户端可以根据接收到的第一数字货币或流通标识向第二货币管理装置申请将第一数字货币兑付成归属于第二客户端的第二数字货币,实现了数字货币在不同客户端之间的流通;此外,在第二货币管理装置兑付第二数字货币的过程中,可以通过第一货币管理装置对第一数字货币或流通标识进行验证,从而保证了支付过程中数字货币的安全性、合法性。
