Description

一种基于电子合同运营的安全支付方法及系统
Figure imgf000003_0001
本发明涉及电子支付领域, 更具体地说, 涉及一种基于电子合同运营的安全支 付方法及系统。
背景技术
[2] 随着互联网和计算机网络技术的发展, 基于信息技术的交易方式, 突破了吋间 和空间的限制, 改变了传统的商业活动, 但同吋也带来了商务活动的信任危机 和电子交易安全性问题的巨大风险。
[3] 电子支付是指单位、 个人通过电子终端, 直接或间接向银行业金融机构发出支 付指令, 实现货币支付与资金转移。 目前, 国内存在的电子支付模式大致有四 种:
[4] 第一种模式, 支付网关模式, 这是电子支付产业发展最成熟的一种模式。 包括 银行和很多第三方支付公司提供的在线支付实际都是银行卡网关支付。 但是这 种提供的实际应用价值相对有限, 而且并不十分方便。
[5] 第二种模式, 就是类似于贝宝 (PayPal) 。 PayPal在美国做得很成功, 但是从 美国到国内, 有巨大的吋空变化, 银行体系, 商家和消费者习惯也是不一样的
。 现在看来这个模式在中国会遇到巨大的困难。
[6] 第三种模式, 就是移动支付。 通过手机让用户随吋随地支付, 这种方式现在吋 机还没有完全成熟, 手机可用性和安全性还是大问题。
[7] 第四种模式, 就是账户支付模式。 比如淘宝的支付宝、 拍拍网的财付通、 易趣 的贝宝等都是属于账户支付模式。
[8] 综观以上的电子支付模式, 无论是各大银行的'网上银行'、 还是支付网关性支 付平台、 虚拟货币的第三方支付平台, 未能有效解决 '电子交易零风险'的电子支 付模式, 严重打击了人们对网上支付的信心, 阻碍了电子支付的广泛使用。 其 主要原因是:
[9] (1) 现有的网络支付 (包括电子银行和第三方支付) 体系, 未能解决电子交 易零风险的电子支付模式。
[10] (2) 对于买家, 存在着银行卡号和密码等私密信息上网的安全隐患。
[11] (3) 买卖交易双方为了规避互联网通信的安全风险, 釆用支付方式普遍釆用 的货到付款, 这对于商家又存在交易成本高和收不到钱的问题。
[12] (3) 对于 PayPal为代表的小额支付工具, 对于买家又存在着付了钱, 又收不 到货或收到次货的风险。
[13] (4) 对于的网络增值服务商发行的虚拟货币 (类似 Q币、 百度币、 盛大币、 网 易币) , 互不往来, 只能标识玩家在各个网络帝国的虚拟商品。
[14] (5) 篡改、 伪造问题, 电子合同的签认、 执行和网上传输过程不具备防篡改 和伪造。 目前电子支付中有很多商家和买家的纠纷问题, 如商家没有发货, 而 买家已经付钱, 买家收到货而否认不付钱等。 这些问题的产生主要是由于电子 合同的签认、 执行流程本身缺陷造成的。 如用户签订电子合同后, 即交给电子 商务平台, 电子商务平台根据该合同与银行可以直接产生划帐行为, 如果电子 合同在到达电子支付平台前或在到达银行认证处理前已经被伪造、 篡改, 则划 帐行为可能在错误的帐号之间进行, 从而导致买到货的用户没有被划帐, 卖了 货的商家没有收到款, 或者银行划了别的帐户的款, 等等问题。
[15] (6) 抵赖问题, 现有电子合同的签认、 执行过程不能做到参与交易的各方都 不能抵赖。
[16] (7) 网银系统存在着信息安全的问题, 网银系统突破了吋间、 空间的限制, 提高了服务质量, 但是网银系统也面临着信息安全风险, 消费方通过
Internet连接银行系统, 用户操作步骤是单独进行处理的, 其操作信息容易被窃 取、 伪冒和篡改, 虽然网银对用户终端也提供一系列安全机制的保证, 但用户 帐号被盗的事件还吋频繁发生, 存在着用户私密信息泄露的安全问题, 网银的 大众版 (银行没有发放证书) , 存在着交易信息抵赖的问题。
[17] 本发明的目的是, 针对的上述电子支付方式存在交易风险的缺陷, 提供一种基 于电子合同运营的安全支付方法及系统。
[18] 本发明实现上述目的的技术方案是: 构造一种基于电子合同运营的安全支付方 法, 包括以下步骤:
[19] (a)根据消费者的真实信息进行注册并分配用户动态交易保障卡所对应的交易帐 号和登陆密码, 所述真实信息包括身份证号、 和 /或手机号, 所述用户动态交易 保障卡通过现金存入方式、 和 /或银行汇票、 和 /或银行转帐方式充值;
[20] (b)运营方系统根据从消费方终端接收的商务请求, 产生电子合同凭证, 每一电 子合同凭证具有唯一的电子合同引擎号及支付子合同、 交付子合同和清算子合 同三方合同要素属性;
[21] (c)运营方系统对电子合同引擎号进行加锁变换计算得到包含第一电子汇票码和 主控密钥的第一联电子汇票和包含第二电子汇票码和动态交易密钥第二联电子 汇票, 并将所述第二联电子汇票的电子汇票码以及支付子合同要素属性发送给 消费方终端签认;
[22] (d)运营方系统接收来自消费方终端对对预定信息及支付子合同要素属性的确认
I口自te!、.,
[23] (e)运营方系统根据支付子合同要素属性的确认消息, 执行从消费者交易账号上 进行扣款, 并将第二联电子汇票的动态交易密钥发送给消费方终端;
[24] (f)运营方系统在扣款成功后向商家系统传送交付子合同要素属性;
[25] (g)从消费方终端接收第二联电子汇票, 并与第一联电子汇票进行联合解锁变换 计算, 从而验证所述第二联电子汇票的真实性, 并发送确认信息给商家系统执 行交付子合同;
[26] (h) 运营方系统根据商家系统提供的第二联电子汇票执行清算子合同, 所述 第二联电子汇票由消费方终端在收货吋提供。
