Description

PIN服务
技术领域
本发明涉及用于PIN服务的方法和系统。
背景技术
在许多(金融的或其它的)交易中,个人识别号(PIN)被用于验证进行交易或服务的实体具有这样做的正当权限。银行和信用卡发行商提供给他们的用户包含有“参考PIN”的智能卡。通常对于这些卡,在交易进行期间,用户输入他们的PIN到智能卡终端中如零售商售货点装置,其接着把它发送到智能卡以和智能卡上的参考PIN比较。如果由终端发送的PIN与参考PIN相匹配,验证过程成功并且认为用户是智能卡的正当持有者,因此具有正当权限进行交易。
在这样的系统中的一个问题是用户忘记PIN的情况。在这种情况下,用户可以尝试猜测PIN,在给定数量的无效尝试后(通常是三次)智能卡可能变成不可用的,例如不能完成当前和任何其后的交易。尽管存在使智能卡返回它原始可用(未锁定)状态的方法,这些方法通常涉及用户不得不亲临特定的安全终端,通常是卡的发行商的或互惠自动取款机(ATM),并且在PIN被忘记的情况中,用户必须首先通过邮寄包含有PIN详细信息的安全信件被重新告知PIN。
这种情况对于用户来说是不方便的因为不仅他们不得不在ATM“解锁”他们的智能卡,而且如果PIN已经被忘记了在重新告知PIN在信中收到之前将有延迟。第二个问题是对于银行或信用卡发行机构来说,从用户到呼叫中心的进入电话有成本,发布PIN重新告知有成本,但是更重要的是,用户可能转而用竞争者的产品或使用不同的其PIN已知的产品。
在另一个例子中,在数字通信装置中使用的SIM(用户标识模块)卡,这样的GSM(移动通信特别小组)‘电话,可以由PIN保护以便装置只有当有效的PIN被输入时才能够使用。在给定数量的无效PIN输入后SIM被锁定,并且只能通过在用户详细信息被验证后从服务提供商获得解锁码,才能够解锁。
专利出版物US-A-6179205公布了利用专门的智能卡读卡器锁定和解锁智能卡中的申请而不需要PIN的系统。读卡器验证它本身到装置,并且申请可以使用读卡器上专门的按钮被锁定或解锁,不需要输入PIN。
专利出版物US-A-6729550公布了具有IC卡读卡器的便携终端和通过便携终端基于用户验证用于锁定/解锁IC卡的装置。
发明内容
根据本发明的一个方面,提供一种PIN服务方法,其中智能卡与智能卡读卡器接口以生成被发送到PIN服务中心的验证消息。如果验证消息被PIN服务验证中心验证确认,确认响应消息被发送回用户。用户在利用智能卡验证确认响应消息的读卡器上输入确认响应消息;然后可以执行PIN服务功能。例如,如果PIN服务功能是公开参考PIN,那么响应确认响应消息的验证PIN可以显示在智能卡读卡器上。如果验证是不成功的,读卡器可以显示合适的信息。
其它PIN服务功能可以包括将智能卡上的参考PIN改变为一个由用户选择的,重置PIN重试次数(例如在给定数量的无效输入后解锁PIN)和/或重置智能卡上的内部配置或参数。
验证和响应消息优选地由动态一次使用码组成,这样验证和响应消息在每个由用户请求的PIN服务功能上变化。在优选的实施例中,这些消息利用密码密钥和智能卡中的一个或多个计数器利用基于对称密钥密码的密码算法如DES或AES生成。因为消息仅一次有效,这提供防御用户合法地获得消息值但是记下或存储它,允许它随后被欺骗性地重放。在优选的实施例中,验证请求消息和响应消息被数学地推导并且相关联,以便为了PIN服务成功,正当的智能卡必须参与原始验证消息的生成和响应消息的验证。这种信息的绑定还防御交易被“撕断”(例如在不同时间使用的来自原始交易的信息)并且确保完整性,因为卡和发行商系统相互验证彼此。
本发明的实施例的一个重要的特征是智能卡密码消息由智能卡内部地单独地生成-读卡器仅作为输入到智能卡的输入机制或作为从智能卡输出到显示器(或者如果在连接的环境中,输出到连接的上游系统)的输出机制。因此读卡器不需要包含用户信息或由卡发行商为用户定制,并且在未连接的环境中读卡器不需要包含任何物理的安全特征,除了窜改证据的形式。
附图说明
现在将参考如下所描述的附图对本发明的特有实施例进行说明。
图1是本发明的实施例中的PIN服务方法的示意图。
图2是实施例中智能卡和智能卡读卡器的图示。
图3是在用户端执行的方法的更详细的图示。
图4是在服务中心端执行的方法的更详细的图示。
具体实施方式
概述
图1中示意性示出一种根据本发明的实施例的PIN服务的方法。用户3把他们的智能卡1插入到读卡器2中,并且选择请求的PIN服务功能。智能卡1生成由读卡器2显示的验证消息。用户1从读卡器2的显示器读出验证消息并且通过用户接口部件4(例如连接到互联网或IVR(交互式语音响应)系统的终端或使用电话的语音呼叫)发送验证消息、请求的PIN服务功能的详细信息和识别用户的信息(例如用户识别信息)到请求接收部件5,例如语音系统、网络服务器或IVR系统。
请求接收部件5发送接收到的信息到一个或多个确认部件6。确认部件6确认验证消息和识别用户请求PIN服务的信息在哪里适用。然后确认部件6生成其内容可能基于由用户请求的PIN服务功能的确认响应消息。确认响应消息被发送到又发送确认响应消息到用户接口部件4并且因此发送回用户3的请求接收部件5。
用户3输入确认响应消息到发送它到智能卡1以进行验证的读卡器2。如果智能卡1成功地确认响应消息,成功消息被生成并由智能卡返回读卡器2,然后成功消息被显示在读卡器显示器上。或者,拒绝消息被生成并由返回读卡器2以显示。可以使用一个或多个成功或拒绝消息。成功或拒绝消息的内容将是针对PIN服务功能请求的内容特定的和确认是否成功。例如,当所请求的PIN服务功能要返回存储在智能卡上的PIN的值时,PIN可以由智能卡1发送回并且由读卡器2在成功消息中显示。
具体实施方式
图2示出读卡器2的详图,其包括数字小键盘8、对应于不同PIN服务功能的功能键9、确定输入的输入键12、显示消息和反映键入的显示器10和智能卡读卡器插槽11。任何符合相关标准(如ISO-7816或EMV)的智能卡、可以由用户插入智能卡读卡器插槽11。智能卡1包括用于电连接到插槽11中的相应触点的触点7,但也可以使用无接触的连接代替。
在另一个实施例中,读卡器2的功能可以被并入智能卡1:例如,智能卡可以包括数字键盘8和显示器10。而这种配置可能增加智能卡的复杂性并且需要集成的电源,利用现有技术是可行的并且进一步的技术进步可能使这种配置更具吸引力。
在另一个替代实施例中,智能卡1可能包括无线链接接口,如蓝牙接口,用于连接到具有键盘和显示器的、然后如读卡器2那样运行的无线装置上。无线装置可以是例如具有蓝牙功能的智能手机或PDA(个人数字助理),其运行提供读卡器2功能的读卡器应用程序。
在另一个替代实施例中,读卡器2可以提供有线或无线的接口到具有屏幕和键盘的装置,如计算机。例如,读卡器2可以包括到运行读卡器应用程序的计算机的智能卡接口和USB(通用串行总线)接口。
现在参考图3和图4:为了执行PIN服务功能,用户3把卡1插入读卡器2并且使用一个在读卡器2上的功能键9选择所请求的功能。读卡器2发送请求到卡1让它利用加密算法13和在卡1内部的密码密钥和优选地包括卡1中递增的计数器生成PIN服务请求密码(PSRQ)。PSRQ包含加密过程的结果和将发送回确认证部件6以验证密码的计数器的足够详细的信息。
在某些实现方式中,其它数据可能还需要包含在和加密过程相关的PSRQ中,如由确认部件6请求的指向数据单元的指针,例如主密码导出密钥。PSRQ被卡1返回到在读卡器显示器10上显示PSRQ的读卡器2。
PSRQ由用户3通过可以是例如电话、网络形式或其它传送装置的用户接口部件4传递到请求接收部件5。除了PSRQ,用户3还发送到(或应请求通过其提供)请求接收部件5以下信息:
用户标识-包括足够的用于确认部件6的材料以验证用户的身份-如生日、母亲的婚前姓氏和/或可记忆的单词。用户识别类型可以由接收部件5请求,其中这是交互式的,如呼叫中心代理或网页。
卡数据-例如,卡账号。
PIN服务请求功能(PSRQ)-代表用户想要执行的PIN服务功能的记忆符号、短语、词语或代码。
一旦从用户接口部件4接收,请求接收部件5发送数据到确认部件6;这可以包括多个通过利用卡数据寻找预期值验证用户识别17的子部件或步骤。除了这个过程之外,确认部件6传递PSRQ、PSRF和卡数据到密码确认步骤18以验证卡密码。密码确认步骤18可以从卡数据库,如指向密码主密钥、算法和关键字索引的指针,取回数据。密码确认步骤18的这个部分的主要目的是确保来自用户的请求从真正的卡发出。为了防御在随后的请求中PSRQ信息的重放,在优选的实施例中密码确认部件6采用跟踪历史卡计数器的步骤。这样,如果在PSRQ中发送或从PSRQ得到的计数被发现少于或等于历史值,那么过程将中断。
如果密码确认过程已经成功地验证请求的密码,另一个的密码将作为PIN服务响应消息(PSRS)19被生成。在优选的实施例中,PSRS的生成将使用来自于原始PSRF的数据以加密地结合请求和响应消息。PSRS还可以结合原始PSRF的值以确保PIN服务响应与请求相匹配并且为了更加安全,还确保由用户3请求的PIN服务不能够被变换成不同的服务或在交易期间改变,如把PIN解锁功能改变成PIN显示功能。
由密码生成步骤19生成的PSRS消息通过确认部件6和请求接收部件5被发送到用户。用户3通过把它键入到智能卡读卡器小而将键盘8PSRS提交到卡1。
为了确认PSRS14,卡使用原始PSRQ和PSRF生成它自己的内部PSRS,然后把它与读卡器2发送的PSRS相比较。基于可用性和显示特性,卡1可能不得不比较部分密码的结果-如密码最右边的“n”个字节,其中“n”或者是读卡器显示器10的最大长度或者是用户3实际的最大数字长度。例如,可以认为用户键入8字节密码是不实际的。
成功的确认要求卡1内部计算的PSRS和读卡器2接收到的相等。如果成功,基于PSRF,由卡内部保持的安全访问条件将基于PIN服务请求允许内部智能卡的功能或者改变PIN的状态到“解锁”或者发送智能卡中的“参考PIN”。因此PSRF对来自智能卡1到读卡器2的响应类型具有直接的影响-或者“OK/成功”状态或者明文“参考PIN”的值。
替代实施例
上述的实施例是说明性的而不是限制本发明。通过阅读上述具体实施方式显而易见的替代实施例可以仍然属于本发明的范围内。
