Description

基于移动智能终端软激励电磁近场互感的虚拟芯片卡系统 技术领域:
本发明涉及电磁近场感应、多级加密和虚拟芯片卡技术,具体涉及一种基于移动智能终端软激励电磁近场互感的虚拟芯片卡系统。
背景技术:
随着信息技术的发展,越来越多的芯片卡出现在我们的生活中,比如银行卡、饭卡、城市交通卡、门禁卡、商城会员卡、借书卡等,这些卡或代替了现金、钥匙等实物,或标示着我们的某种身份权限,使得我们的生活更加便利。然而,各种不同的芯片卡由不同的机构发放,通常采用不同的读取装置和技术,数据交互手段不同,且各种芯片卡的安全加密级别也存在很大差异。比如银行卡通过近场通信与远程通信相结合的方式获取数据,即银行卡与POS机近场通信,POS机读取银行卡的相关信息,POS机与数据中心通过远程通信进行信息交互,POS机需要实时网络连接到远程数据中心进行身份验证和数据交互,加密级别较高;交通卡、饭卡等小额支付需要对应各自的近场读卡器完成交易,效率较高,加密级别较低;再如门禁卡一般对应其近场读卡器,其密码通常也在近场读卡器进行设置和验证。因此众多的芯片卡难以统一形成一卡通,随身携带、管理这么多卡给我们的生活带来了一些麻烦。
芯片卡,即含有集成电路的卡片,集成电路中通常包含有存储单元和微处理单元,是无源的,在使用时需要读卡器接触芯片卡上的若干触点为其加电,激活电路,以实现数据的读取,其处理能力和存储能力均有限。而我们日常生活中,几乎人人都会随身携带手机,有的人还会随身携带平板电脑等移动电子终端,这些移动电子终端中不仅有处理器和存储单元,且是有源的,不需要依赖其它设备为其施加工作电压,能实现主动数据发送和处理,其处理器也远比芯片卡中的微处理单元的处理能力要强,其内存也比芯片卡中的存储单元要大。同时,这些移动电子终端中还有WIFI、3G/4G等其他远程通信功能。因此如果能将手机等移 动电子终端与芯片卡相结合,其使用将会更加方便、安全。芯片卡与移动电子终端结合,可以通过远程通信或者近场通信获取数据,实现不同的应用。
将芯片卡与移动电子终端的远程通信相结合,出现了以微信支付、支付宝支付为代表的移动支付,且得到了一定的推广应用。移动支付将我们的银行卡与手机应用程序绑定使用,也可以通过关注公众号实现商家的电子会员卡等功能,但是使用微信或者支付宝必须有网络连接,需要登录到远程服务器端验证身份和获取数据,且常常需要通过扫描二维码的形式获取商家的信息,操作比较繁琐,限制了上述应用的使用效率和使用场景。以至于在推广至城市交通、报纸购买、快餐购买、自动售货机、食堂以及农贸市场等使用人员密集且要求随时随地高效的小额零售支付等领域时,效率较低,容易引起用户拥堵和排长队现象。
将芯片卡与移动电子终端的近场信息交互相结合的概念虽然有见诸报端,但是未见大规模应用。目前,基于近场信息交互的芯片卡应用较广,比如乘坐地铁、公交时的交通卡、开门的门禁卡等,但是将芯片卡与移动电子终端的近场信息交互相结合的应用,比如“刷手机乘公交”“刷手机开门”等,推广至日常应用中还需要一定的成本。这是由于目前利用移动电子终端进行近场信息交互的主要手段是近距离无线通信技术(即NFC,Near Field Communication)。NFC技术是一种非接触式射频技术,主要利用电磁波实现近场通信,该技术需要在移动电子终端上嵌入NFC芯片,并非所有的移动电子终端能直接使用。因此,用户需要更换具有NFC功能的移动终端才可实现。另一种近场信息交互主要是利用声波实现,如支付宝的声波支付,易受到外界可听声波噪声的干扰,容易被监听,保密性和安全性差;且通信设备的扬声器和麦克风的性能对通信质量影响较大,通信性能鲁棒性不高。
综上所述,如果能以移动电子终端的处理器、存储单元等固有硬件取代芯片卡的硬件,不改变移动智能终端硬件,不同芯片卡对应不同的软件程序,形成虚拟芯片卡系统,并将近场信息交互与远程通信结合、将近场加密和远程服务器端加密结合,便能极大地拓展芯片卡的使用场景,给我们的使用带来更多便利。同时,由于移动终端的芯片处理能力更强,虚拟芯片卡较原芯片卡性能还能得到提升,安全保密性得到更好的保障。用户只需随身携带手机等移动电子终端,便可以方便地代替各种加密级别、各种使用场合的多种芯片卡,轻松实现高效、安全、 方便的“刷手机乘公交”“刷手机开门”“刷手机购物”等。
发明内容:
为克服现在人们需随身携带众多芯片卡,且芯片卡使用的高效性与安全性难以兼得,即安全性好的芯片卡使用繁琐、使用快捷的芯片卡安全性不高等问题,本发明提出一种基于移动智能终端软激励电磁近场互感的虚拟芯片卡系统。人的大脑在思考时,会产生不同的脑电波,从而激发不同的脑磁信号,通过获取脑磁信号并配合相应的分析处理可以识别人的意念并实现意念力控制。与之相类似的,移动智能终端在运行程序时,会产生内部电流,同时会激发相应的交变磁场,本发明中,将该交变磁场称为软激励磁场。通过设计特定的移动智能终端程序,可以控制激发的软激励磁场的频率及幅度等参数,从而携带不同的信息。利用磁场接收装置,就可以接收这些参数,从而获取移动智能终端要传递的信息。根据此原理,本发明通过以下技术方案实现:
本发明所述的基于移动智能终端软激励电磁近场互感的虚拟芯片卡系统,包括移动智能终端、宽频电磁读卡器和芯片卡数据中心。所述的移动智能终端是指带程序运行功能的移动电子终端,如手机、平板电脑。移动智能终端与宽频电磁读卡器的物理距离很近,就像公交卡与公交车上的刷卡器一样,它们之间的信息交互称为近场信息交互。而移动智能终端与芯片卡数据中心的物理距离可以非常远,就像银行卡与银行服务器一样,它们之间的信息交互称为远程信息交互。宽频电磁读卡器与芯片卡数据中心也是远程信息交互。
上述移动智能终端与宽频电磁读卡器的近场信息交互通过近场软激励电磁互感来实现。所述近场软激励电磁信号是在移动智能终端中运行特定的程序(例如向USB接口、屏幕显示驱动接口、音频接口、SD卡接口等发送特定格式的数据等)所激发,无需改变或者添加移动智能终端的固有硬件。移动智能终端运行特定程序时,其固有硬件产生内部电流,激发出具有某种特性的磁场,即具有不同的频率和幅度的磁场,从而携带不同的信息。这个过程如同人的大脑在思考问题时,也会产生相应的脑电波和脑磁信号。近场信息交互的数码率与所激发的交变磁场频带相关。移动智能终端程序激发的交变磁场的频带与移动智能终端程序 运行的速度有关,而这又与移动智能终端处理器的计算速度有关,也就是与移动智能终端的时钟频率有关。以现在的移动智能终端的硬件配置,大部分移动智能终端可实现高达兆赫兹级的交变磁场,频带比音频信号宽,实现宽频电磁交互。

基于移动智能终端软激励电磁近场互感的虚拟芯片卡系统,其安全性通过多重防护机制保证,多重防护机制主要体现在以下四个方面:
1.开启密码:进入虚拟芯片卡应用程序时需要输入密码;
2.多级密码:对安全性要求不同的应用,系统有不同的工作流程和加密方法,采用多级密码保护,实现不同的安全级别;
3.联名审核:进行操作时可选择多人依次进行验证,以提高安全性;
4.快速挂失:移动智能终端丢失时,可以快速挂失,防止盗用。
上述开启密码,由用户通过移动智能终端设定,在进入移动智能终端的虚拟芯片卡应用程序时需要输入。开启密码可以保证移动智能终端被非法用户获取后,非法用户无法轻易进入虚拟芯片卡应用程序进行操作。
上述多级密码通过以下技术方案实现。多级密码分为K个保护级别:第0级密码的保护方案最简单,保护级别最低;第K-1级密码的保护方案最复杂,保护级别最高。使用第0级密码时,仅需移动智能终端和宽频电磁读卡器交互信息即可完成,无需芯片卡数据中心与移动智能终端进行验证及确认。使用第1级到第K-1级密码时,需要芯片卡数据中心与移动智能终端进行验证及确认。
第0级密码可用于对效率、便捷性要求较高、同时对安全性要求较低的应用场景,比如交通卡或者购买报纸、饮料等一些小额支付应用。使用第0级密码的过程如下:
1)移动智能终端用户启动移动智能终端上的虚拟芯片卡应用程序,并输入开启密码。如果开启密码正确,进入虚拟芯片卡应用程序;如果开启密码错误,则重新输入开启密码。如果连续输入错误的开启密码达到一定次数后,则锁定虚拟芯片卡应用程序,需要到芯片卡发放机构解锁;
2)宽频电磁读卡器在其人机交互界面显示当前应用信息,即此次应用产生的信息,比如对于银行卡交易,显示的是此次交易信息,对于借书卡,显示的是借阅信息;
3)移动智能终端用户确认步骤2)中的当前应用信息无误后,将移动智能终端靠近宽频电磁读卡器;
4)移动智能终端的软激励电磁收发模块将移动智能终端的账号信息加密后通过软激励电磁收发模块发送至宽频电磁读卡器;

7)宽频电磁读卡器将收到的加密后的移动智能终端账号信息以及当前应用信息加密后发送至芯片卡数据中心中对应的应用数据中心;
8)相应的应用数据中心收到信息后,进行解密,分别获取当前应用信息和移动智能终端的账号信息,更新其芯片卡数据存储模块中该移动智能终端用户的相关应用信息。
上述步骤4)中,移动智能终端的虚拟芯片卡应用程序加密用户账户的具体过程如下:移动智能终端将账号信息和虚拟芯片卡应用程序储存的同步码进行异或,得到加密后的数据。
所述同步码为具有一定长度的二进制随机序列。同步码由芯片卡数据中心设定,并与移动智能终端共享,但对于宽频电磁读卡器保密。
上述步骤7)中,宽频电磁读卡器的加密方法可以采用多种加密手段,如RSA等。
上述步骤8)中,芯片卡数据中心解密数据的过程分为两步:首先,根据宽频电磁读卡器采用的数据加密方法,采用相应的数据解密方法,获取宽频电磁读卡器发来的数据;然后,将加密的移动智能终端用户账户信息和同步码进行异或,获取用户账号信息。
对于上述步骤7)和步骤8),如果宽频电磁读卡器和芯片卡数据中心之间的通信正常工作时,可实时完成步骤7)和步骤8);如果宽频电磁读卡器和芯片卡数据中心之间的通信不能正常工作时,步骤7)和步骤8)可等待通信正常时再完成。因此,移动终端用户的芯片卡使用不需要移动智能终端的无线网络,也不要求宽频电磁读卡器和芯片卡数据中心实时网络在线,只需要通过软激励宽频电磁信号即可完成,可实现芯片卡用户高效、快捷、方便地用卡体验。
第1级至第K-1级密码可用于对安全性要求较高,而实时性要求略低的应用场景,比如较大金额的支付应用。使用第1级至第K-1级密码的交易过程如下:
1)移动智能终端用户启动虚拟芯片卡应用程序,并输入开启密码。如果开启密码正确,进入虚拟芯片卡应用程序;如果开启密码错误,则重新输入密码。如果连续输入错误的开启密码达到一定次数后,则锁定虚拟芯片卡应用程序,需要到芯片卡发放机构解锁;
2)宽频电磁读卡器在其人机交互界面显示当前应用信息,即此次应用产生的信息,比如对于银行卡交易,显示的是此次交易信息,对于借书卡,显示的是借阅信息;
3)移动智能终端用户确认步骤2)中的当前应用信息无误后,将移动智能终端靠近宽频电磁读卡器;
4)移动智能终端的软激励电磁收发模块将移动智能终端的账号信息加密后通过软激励电磁收发模块发送至宽频电磁读卡器;
5)宽频电磁读卡器将收到的加密后的移动智能终端账号信息以及当前应用信息再加密后发送至对应的应用数据中心;
6)相应的应用数据中心收到信息后,进行解密,分别获取当前应用信息和移动智能终端的账号信息;
7)应用数据中心通过无线通信方式将确认信息以及最新的同步码发送给移动智能终端;
8)移动智能终端用户收到确认信息后,确认无误,输入确认密码,并再次靠近宽频电磁读卡器;
9)移动智能终端对上述信息进行加密,并通过软激励电磁收发模块发送给宽频电磁读卡器;
10)宽频电磁读卡器将收到的信息再次加密后发送给应用数据中心;
11)相应的应用数据中心收到信息后,进行解密,获取移动智能终端的用户确认密码,验证确认密码是否正确。如果正确,进入步骤12;否则,进入步骤13;
12)应用数据中心更新其芯片卡数据存储模块中该移动智能终端用户的相关应用信息;并向宽频电磁读卡器和移动智能终端发送操作成功信息,移动智能终端更新其智能终端处理模块中的账户应用信息;
13)应用数据中心向宽频电磁读卡器发送消息,拒绝执行此次操作,并向移动智能终端用户发送操作失败信息。
上述步骤4)中,移动智能终端的虚拟芯片卡应用程序加密用户账户的具体过程如下:移动智能终端将账户信息和虚拟芯片卡应用程序储存的同步码进行异或,得到加密后的数据。
上述步骤5)中,宽频电磁读卡器的加密方法可以采用多种加密手段,如RSA等。
上述步骤6)中,芯片卡数据中心解密数据的过程分为两步:首先,根据宽 频电磁读卡器采用的数据加密方法,采用相应的数据解密方法,获取宽频电磁读卡器发来的数据;然后,将加密的移动智能终端用户账户信息和同步码进行异或,获取用户账户信息。
所述同步码为具有一定长度的二进制随机序列。同步码由芯片卡数据中心设定,并与移动智能终端共享,但对于宽频电磁读卡器保密。
上述步骤9)中,移动智能终端的加密过程如下:移动智能终端将用户的确认密码经过不可逆加密算法,所得加密结果和虚拟芯片卡应用程序更新的同步码进行异或,得到双重加密后的数据。
第1级至第K-1级密码不同的保护级别体现在两方面:首先,用户的确认密码应该由简至繁;其次,用于异或的同步码应保密性更好,比如使用更长的同步码。
上述步骤11)中,芯片卡数据中心解密数据的过程分为两步:首先,根据宽频电磁读卡器采用的数据加密方法,采用相应的数据解密方法,获取宽频电磁读卡器发来的数据;然后,将加密的移动智能终端用户确认密码和当前同步码进行异或,得到经过不可逆加密算法的确认密码,与所存储的不可逆加密算法的加密结果比较,如果相同,确认密码验证通过;如果错误,确认密码验证失败。
所述联名审核,指进行操作时需要多人在一定的时间内依次进行验证,仅当所有验证通过,方可批准执行操作。联名审核可用于对安全性要求较高、需要多级审批、或需要多人在场等应用场景。每个人的验证过程可采用第1级至第K-1级密码中的任意一种。
所述快速挂失,指当用户的移动智能终端(移动智能终端1)丢失或者账号出现异常时,可以通过他人的移动智能终端(移动智能终端2)在短时间内进行挂失。他人挂失时,提供需要挂失的账号和挂失账号的挂失密码,方能进行挂失。移动智能终端的虚拟芯片卡快速挂失步骤应包含:
1)在移动智能终端2的虚拟芯片卡应用程序中输入挂失账号(即移动智能终端1的账号)和挂失密码。
2)移动智能终端2的远程通信模块将上述挂失账号和挂失密码发送给芯片卡数据中心中相应的应用数据中心。
3)应用数据中心的移动智能终端数据收发模块接收到挂失账号和挂失密码 后,查询该挂失账户在芯片卡数据存储模块中存储的挂失密码与接收到的挂失密码是否一致,如果一致,则将芯片卡数据存储模块中账户的状态更新为挂失状态,应用数据中心通过移动智能终端数据收发模块返回“挂失成功”给移动智能终端2;如果不一致,则不需更新该账户的状态,应用数据中心通过移动智能终端数据收发模块返回“挂失失败”给移动智能终端2。
本发明的有益效果是:

3、对安全性要求较低的应用无需网络连接。对于交通卡或者购买报纸、饮料等一些小额支付应用,不需要移动智能终端连接到网络,仅通过软激励电磁信号即可完成,效率高,实时性好。
4、本系统支持联名审核。一些安全级别较高的应用需要多人确认,比如企业银行卡的使用。本系统支持联名审核功能,安全级别高。

第0级密码可用于对效率、便捷性要求较高、同时对安全性要求较低的应用场景,比如交通卡或者购买报纸、饮料等一些小额支付应用。第1级至第K-1 级密码可用于对安全性要求较高,而实时性要求略低的应用场景,比如较大金额的支付应用。
如图6所示,以智能手机的虚拟银行卡在自动售货机上进行小额支付购买物品为例,在本例中,移动智能终端即是智能手机,宽频电磁读卡器安装在自动售货机上,下面分步骤介绍系统以0级密码工作的使用步骤:
1)移动智能终端用户启动移动智能终端上的虚拟芯片卡应用程序,并输入开启密码。如果开启密码正确,进入虚拟芯片卡应用程序;如果开启密码错误,则重新输入开启密码。如果连续输入错误的开启密码达到一定次数后,则锁定虚拟芯片卡应用程序,需要到芯片卡发放机构解锁;
2)宽频电磁读卡器在其人机交互界面显示当前交易信息,比如购买物品种类,应支付金额等;
3)移动智能终端用户确认步骤2)中的当前交易信息无误后,将移动智能终端靠近宽频电磁读卡器;
4)移动智能终端的软激励电磁收发模块将移动智能终端的账号信息加密后通过软激励电磁收发模块发送至宽频电磁读卡器;
5)宽频电磁读卡器接收移动智能终端发送的加密后的账号信息,宽频电磁读卡器通过宽频电磁发送模块将需要更新的芯片卡交易信息发送给移动智能终端的软激励电磁收发模块;宽频电磁读卡器的控制模块发放用户所购买的物品;
6)移动智能终端根据软激励电磁收发模块接收到的信息更新智能终端处理模块中的用户账户的应用信息,移动智能终端用户即可完成离开;
7)宽频电磁读卡器将收到的加密后的移动智能终端的账号信息以及当前交易信息加密后发送至芯片卡数据中心中对应的应用数据中心;
8)相应的应用数据中心收到信息后,进行解密,分别获取当前交易信息和移动智能终端的账号信息,更新其芯片卡数据存储模块中该移动智能终端用户的相关应用信息。
上述步骤4)中,移动智能终端的虚拟芯片卡应用程序加密用户账户的具体过程如下:移动智能终端将账号信息和虚拟芯片卡应用程序储存的同步码进行异或,得到加密后的数据。
所述同步码为具有一定长度的二进制随机序列。同步码由芯片卡数据中心设 定,并与移动智能终端共享,但对于宽频电磁读卡器保密。
上述步骤7)中,宽频电磁读卡器的加密方法可以采用多种加密手段,如RSA等。
上述步骤8)中,芯片卡数据中心解密数据的过程分为两步:首先,根据宽频电磁读卡器采用的数据加密方法,采用相应的数据解密方法,获取宽频电磁读卡器发来的数据;然后,将加密的移动智能终端用户账户信息和同步码进行异或,获取用户账号信息。
对于上述步骤7)和步骤8),如果宽频电磁读卡器和芯片卡数据中心之间的通信正常工作时,可实时完成步骤7)和步骤8);如果宽频电磁读卡器和芯片卡数据中心之间的通信不能正常工作时,步骤7)和步骤8)可等待通信正常时再完成。因此,移动终端用户的芯片卡使用不需要移动智能终端的无线网络,也不要求宽频电磁读卡器和芯片卡数据中心实时网络在线,只需要通过软激励宽频电磁信号即可完成,可实现芯片卡用户高效、快捷、方便地用卡体验。
如图7所示,以智能手机的虚拟银行卡进行大额支付为例,分步骤介绍系统使用第1级至第K-1级密码时的交易过程:
1)移动智能终端用户启动虚拟芯片卡应用程序,并输入开启密码。如果开启密码正确,进入虚拟芯片卡应用程序;如果开启密码错误,则重新输入密码。如果连续输入错误的开启密码达到一定次数后,则锁定虚拟芯片卡应用程序,需要到芯片卡发放机构解锁;
2)宽频电磁读卡器在其人机交互界面显示当前应用信息,即此次应用产生的信息,比如对于银行卡交易,显示的是此次交易信息,对于借书卡,显示的是借阅信息;
3)移动智能终端用户确认步骤2)中的当前交易信息无误后,将移动智能终端靠近宽频电磁读卡器;
4)移动智能终端的软激励电磁收发模块将移动智能终端的账号信息加密后通过软激励电磁收发模块发送至宽频电磁读卡器;
5)宽频电磁读卡器将收到的加密后的移动智能终端账号信息以及当前交易信息再加密后发送至对应的应用数据中心;
6)相应的应用数据中心收到信息后,进行解密,分别获取当前交易信息和 移动智能终端的账号信息;

11)相应的应用数据中心收到信息后,进行解密,获取移动智能终端的用户确认密码,验证确认密码是否正确。如果正确,进入步骤12;否则,进入步骤13;
12)应用数据中心更新其芯片卡数据存储模块中该移动智能终端用户的相关应用信息;并向宽频电磁读卡器和移动智能终端发送操作成功信息,移动智能终端更新其智能终端处理模块中的账户应用信息;
13)应用数据中心向宽频电磁读卡器发送消息,拒绝执行此次操作,并向移动智能终端用户发送操作失败信息。
上述步骤4)中,移动智能终端的虚拟芯片卡应用程序加密用户账户的具体过程如下:移动智能终端将账户信息和虚拟芯片卡应用程序储存的同步码进行异或,得到加密后的数据。

所述同步码为具有一定长度的二进制随机序列。同步码由芯片卡数据中心设定,并与移动智能终端共享,但对于宽频电磁读卡器保密。
上述步骤9)中,移动智能终端的加密过程如下:移动智能终端将用户的确认密码经过hash函数,所得结果和虚拟芯片卡应用程序更新的同步码进行异或, 得到加密后的数据。
第1级至第K-1级密码不同的保护级别体现在两方面:首先,用户的确认密码应该由简至繁;其次,用于异或的同步码应保密性更好,比如使用更长的同步码。
上述步骤11)中,芯片卡数据中心解密数据的过程分为两步:首先,根据宽频电磁读卡器采用的数据加密方法,采用相应的数据解密方法,获取宽频电磁读卡器发来的数据;然后,将加密的移动智能终端用户确认密码和当前同步码进行异或,得到经过hash函数的确认密码,与所存储的hash函数结果比较,如果相同,确认密码验证通过;如果错误,确认密码验证失败。
所述联名审核,指进行操作时需要多人在一定的时间内依次进行验证,仅当所有验证通过,方可批准执行操作。联名审核可用于对安全性要求较高、需要多级审批、或需要多人在场等应用场景。每个人的验证过程可采用第1级至第K-1级密码中的任意一种。
