相关申请的交叉参考
本申请要求2012年10月18日提交的美国临时专利申请号61/715,426的权益,其全部内容被引入本文作为参考。
发明背景
射频识别(RFID)装置,包括能够近场通信(NFC)的RFID装置在内,被用于多种目的。通常这种装置作为标签或标记形成,并且可用于关联对象与识别码或其他数据,如网站数据。这种RFID装置可以是无源的,并且在接收信号如来自RFID或能够NFC的读取器的激励信号后可被供能。然后该装置可以期望通信响应,或提供与RFID装置关联的产品、项目或服务的相关信息。
具体地,NFC是数据交换协议,其被设计以允许装置——包括适当装备的移动电话及类似物——与例如诸如销售终端点和运输系统的检票口的基础设施或“智能海报”或“触点”形式的RFID装置相互作用。在这种情况下,将能够NFC的装置带到这种基础设施或RFID装置附近可导致数据传输至能够NFC的装置,导致例如网页打开、通过接受媒体流、或多种其他功能的任一种。
通常,将产品、项目或服务与RFID装置关联的方式是将RFID装置物理连接或粘附于产品或项目,或将其与产品、项目或服务相关的广告如上述“智能海报”或“触点”关联。例如,RFID标记可粘合性地连接于对象,或可另外具有直接连接于对象的表面。RFID标签可以其他方式固定于对象,如通过利用塑料紧固件、绳带或其他紧固机构。然后这种RFID装置可向位于或置于RFID装置附近的能够NFC的装置提供数据。
另外,通常将RFID装置以隐藏或保护RFID装置的方式与产品或项目、或广告项目关联。这种方法可提供安全性,防止移除或误用RFID装置。但是,在这种情况下,并且特别是关于被设计以通过能够NFC的移动电话和装置向顾客输送信息的能够NFC的装置,广告或产品上存在指定区域(触点),其指示如果将能够NFC的装置置于十分接近RFID装置关联区域的位置则可获得信息。但是,随着随后知道可从这种区域获得信息,破坏或盗版RFID装置通常被置于十分接近指示的NFC区域的位置。破坏或盗版装置通常包含欺骗性、误导性、不期望的或恶意的信息。这些装置可连接于或粘附于产品和项目或那些项目关联的广告,导致不当或恶意的信息不知不觉被传达至用户的能够NFC的装置。本发明提供针对该问题的可能的解决方案。
发明概述
向RFID和NFC系统提供安全性的方法、系统和设备。在一些示例性实施方式中,智能海报可用于提供与RFID或能够NFC的装置的适当的或期望的通信。这种示例性实施方式可利用授权NFC标签与能够NFC的装置通信,并在激活授权NFC标签后可触发一个或多个相关项目的激活或出现,如视觉提示。另外,NFC安全系统的方面,其可包括安全区、活动状态和在检测到安全侵犯时实施的动作。
附图简述
本发明实施方式的优势通过下文示例性实施方式的详述而显而易见。下文详述应与附图结合考虑,在附图中:
图1是具有嵌入式RFID装置的海报的示例性视图。
图2是具有嵌入式RFID装置和安全系统的海报的示例性视图。
图3是显示可与RFID装置一起应用的安全系统的示例图。
发明详述
本发明的方面在涉及本发明具体实施方式的下文描述和相关附图中被公开。可设计替代性实施方式而没有脱离本发明的精神和范围。另外,本发明示例性实施方式的公知要素未被详细描述,或将被省略,以便不会使本发明相关细节模糊不清。进一步,为促进对描述的理解,下面讨论本文所用的若干术语。
如本文所用,词语“示例性”意为“作为实例、例子或示例”。本文描述的实施方式不是限制性的,而仅是示例性的。应理解,所述实施方式不一定被解释为相对于其他实施方式优选或有利。此外,术语“本发明的实施方式”、“实施方式”或“发明”不要求本发明的所有实施方式包括所讨论的特征、优势或操作方式。
总体上,参考图1-3,智能海报,如海报——包括授权RFID装置,该授权RFID装置包括授权NFC标签,可用于提供与RFID或能够NFC的装置的适当的或期望的通信。这种示例性实施方式可利用授权NFC标签与能够NFC的装置通信,和在激活授权NFC标签后可触发一个或多个相关项目的激活或出现,如视觉提示。另外,NFC安全系统的方面,其可包括安全区、活动状态和在检测到安全侵犯时实施的动作。另外,虽然所述一些示例性实施方式讨论了RFID或NFC通信能力,但可理解,这种能力可在相同装置中实施,或这种能力可在一些实例中可互换地应用。
现参考示例性图1,提供具有海报106以及支撑框架102的显示器100的视图。在示例性实施方式中,海报106可以是任何类型的海报,由任何类型的材料组成,并且可用于传达任何类型的信息。海报可由任何可接受的材料形成,包括但不限于纸、箔和塑料/膜。传达的信息可以是任何期望的类型,包括但不限于,广告、个人护理、健康护理和产品或服务信息。结构框架102可提供如下的安全外壳:海报106;授权通信装置,如授权NFC标签114;和期望的相关组件或电子器件,诸如但不限于,照明和NFC安全系统。框架102可以是任何类型的期望的框架,并且可由任何期望的材料组成。另外,框架102可以是这样的,其形成有集成天线,或可加装天线。
在图1中,示例性海报106可包含视觉信息108,例如产品广告或任何其他期望的视觉信息。另外,NFC标签114可被提供以与其关联的视觉指示器116。视觉指示器116可以是任何类型的静态或电子视觉指示器,并且可例如用于将用户引导至适当区域,以布置可读取授权NFC标签114的能够NFC的装置。这种装置可包括具有合并在电话中的NFC询问器的移动电话,或具有与其关联的NFC询问器的任何其它装置。将适当装备的移动电话(或其它能够NFC的装置)布置在指示区116中可允许读取NFC标签114的内容。这种内容可以是任何类型的信息或数据,例如可指向包含海报106的视觉信息108的相关信息的网站的数据。
智能海报或标识还可装备低功率接收器或“监控器(watch dog)”装置,该低功率接收器或“监控器”装置将允许NFC标签114检测一定范围内是否存在NFC读取装置如智能电话,该范围大于读取装置能够与表面上或区域内的NFC标签通常相互作用的范围。预检测或监控器装置的一个用途是允许在用户或顾客靠近到足以读取盗版标签(如有)前对侵犯/盗版标签进行安全扫描。由于扫描仅在顾客靠近时激活,平均功率消耗很低,允许由可位于标签中或关联标签的电池来支持该功能。这种监控器装置的预检测还可用于激活视觉、听觉或其他功能,如照明标识或向即将到来的顾客发出问候。通过在保护范围内布置监控器装置,可监测NFC标签,并且因为监控器单元可由于预检测而被电池驱动,其可被灵活布置,而不耗费额外的实施监控器装置应用的布线或支撑结构。
仍参考示例性图1,盗版或破坏标签104显示为附于海报106的视觉表面。破坏标签104的内容可包含任何类型的信息或数据。在一个实施方式中,破坏标签的内容包括使用户装置变为指向包含非授权信息或可在读取装置上安装恶意软件的网站的信息或数据。
如关于示例性图1所述,授权NFC标签114与海报106关联。授权NFC标签114可单独用于提供授权NFC标签114和能够NFC的读取器之间的期望或授权的通信,或可用于NFC安全系统,如本文更详细描述。另外,授权NFC标签114可以是这样的:其可起到防止或限制接近或直接覆盖NFC标签114布置的破坏标签104或其他非授权或非期望装置的功能的作用。授权NFC标签114可以多种方式中的任一种形成,并且包括元件如相对高介电常数基底、相对高磁导率基底,或包括超过形成天线所需的传导性材料的区域。相对高介电常数材料可进一步限定为介电常数大于二氧化硅介电常数或3.9的材料。实例材料包括硅酸铪、硅酸锆、二氧化铪和二氧化锆,但可使用本领域已知的任何高介电材料。磁导率通常表示为相对磁导率(μR),具体介质磁导率与自由空间磁导率的比,或材料吸引和维持磁场的能力。高相对磁导率可限定为大于1。高相对磁导率基底的实例包括铁磁性材料如镍或铁。[http://www.microwaves101.com/encyclopedia/highpermeability.cfm]。这些特征将导致附近布置的破坏标签强烈失谐,因此功能降低。在一些实施方式中,支撑海报的结构或海报本身将包括相对高介电常数、高磁导率和传导性区域,或这些的任何组合,并且授权标签114可被设计用于可补偿这些阻碍或干扰的加载的谐振频率。被设计用于多种应用的一般良性基底的非授权或破坏标签其性能可由于结构、海报或两者中并入的元件的存在和功能而显著削弱或失效。通过具有表面情况的现有知识,授权标签114可实施具有特殊的“指定”或授权的RFID装置特性的设想以在表面上发挥作用。因此,不具有这种知识的任何非授权或破坏标签不可以起到提供其预期通信能力的作用。
图2可提供显示器200的示例性视图,其具有显示器框架202,该显示器框架202可并入具有视觉信息208的海报206和授权NFC标签214。另外,在这种示例性实施方式中,还可提供通过视觉向导216指示的NFC读取区。进一步,显示器202可并入NFC安全系统(下文关于示例性图3更详细描述),其可保护显示器200隔离破坏标签204或任何数量的其他破坏标签。安全系统可包括安全控制器210、与安全控制器210关联的一个或多个子组装件电路板212、和NFC天线218。例如,安全控制器210的一个或多个子组装件电路板212可提供用于安全系统操作的功能。另外,NFC天线218可提供询问区域,其可基本上等同于显示器200的整个表面。因此扫描区域可包括海报206、NFC指示的读取区216和显示器框架202的全部其它表面、以及位于显示器200附近或邻近的一些区域,如需。
还参考示例性图2,非授权标签204可显示为附于海报206的一部分。安全系统,如下文更详细描述,可周期性地激发NFC天线218扫描附于显示器202的任意和全部NFC标签。然后安全系统可检测破坏标签204(或一些其它非授权装置),并选择要进行的适当或期望的动作或动作组。在一个示例性实施方式中,安全系统可首先扫描破坏标签204的存储器内容。然后,根据破坏标签204的持续状态,安全系统可试图覆写破坏标签204的存储器内容或以其他方式利用多数NFC标签通常存在的“杀死”指令禁用破坏标签204的功能。可通过安全控制器210实施的另外的或可选的步骤可包括用噪声干扰通信通道,发出警报,或关闭与显示器200关联的显示器灯,以指示故障状态,或利用并入系统的网络连接来发出警告信号。这种步骤被如下更详细描述。
图3可提供与NFC或RFID系统联合应用的安全系统300的组件的功能框图形式的示例性视图。安全控制器210可以是相对于系统中的全部其它控制器的主要控制器。此示例性实施方式所示的系统中的次要控制器可包括网络控制器320、NFC控制器322和显示器控制器310及其他,如需。此示例性实施方式中的次要控制器310、320、322可通过缆线如缆线318、312和314连接于安全控制器210。网络控制器320可进一步包括网络收发器,其可支持有线标准如Ethernet或无线网络标准如蜂窝网络、Wi-Fi和蓝牙连接,或任何其他有线或无线标准,如需。NFC控制器322可提供NFC功能,如但不限于,询问、读取、写入和禁用NFC标签。NFC控制器322可通过缆线308连接于NFC天线218。NFC天线218可包括一个或多个近场元件,其可向位于NFC天线218附近的NFC标签提供能量和通信,并且可以被布置在显示器200上或周围的任何位置,例如在框架202中。显示器控制器310可通过连接缆线306发送和接收来自显示器200的信号。
还参考示例性图3,显示器200可包含控制显示器200中的电子器件例如视觉照明器件、听觉电子扬声器、蜂鸣器和锁定机构的组件或方法。显示器200可通过利用扳钮开关或任何其它期望的组件指示状态。另外,并入显示器200的传感器可包括光传感器、运动传感器、接近传感器、振动传感器及类似物。来自传感器和开关的信号可提供NFC显示器200的扫描间隔和安全元件的控制信息。例如,安全系统300可被编程以在用户或顾客存在时停止扫描,使得用户的NFC移动装置不干扰和可进行期望的NFC通信。
现参考示例性图2和示例性图3,NFC安全系统300保护的区域可以是一个或多个区(regions或zones)。这种区(regions或zones)可以是被认为是适于或期望用于保护显示器200的任何尺寸。该区可处于显示器界限内。在一些示例性实施方式中,安全区可延伸越过显示器200的物理界限。进一步,对于具有多个区的NFC安全系统300而言,每个区的尺寸和配置可不同于所有其他区的配置。用于固定这种区的技术可通过近场或远场结构的任何期望的组合来实现。近场结构的实例可包括感应线圈、电容结构或传输线。远场结构的实例可包括用作检测电磁波能量的天线的传导性材料的任何物理配置。用于区域安全的结构可以适于RFID询问、检测交变场或传输交变场的配置操作。
在一个示例性实施方式中,可相应于框架202尺寸的区或区域可具有大感应线圈天线218,其可遵循显示器200的视觉部分正后方的外周。线圈天线218可被激发以提供用于停用非授权标签204的交变磁场。线圈天线218的能量和控制可由NFC控制器322提供,该NFC控制器322可试图询问附于显示器200的可视面的任何NFC标签,如破坏标签204。
在另一示例性实施方式中,还参考图2和图3,安全扫描区可通过位于显示器200上的一个或多个磁性探针生成。磁性探针可用于扫描交变磁场,该交变磁场可相应于用户装置的NFC询问系统。在不存在授权NFC标签——如位于指示器216附近的授权NFC标签214——的区域中检测到的高功率场可指示显示器上非授权标签204的存在。
在又一示例性实施方式中,安全区可通过显示器200内的天线218来提供,该天线218可记录处于NFC操作射频的远场信号。该信号可通过安全系统的组件分析以得到与显示器200上的授权NFC标签214相关的定时和内容。分析数据中的不一致或不规律可指示非授权标签204的存在。
在又一示例性实施方式中,安全系统可启动与显示器200关联的区域或区的扫描。这可通过监控器类型装置或被提供用于这种活动的其他组件来实现。由安全系统执行的扫描活动可通过恒定轮询操作,或可通过条件规则触发,如需。扫描活动的条件控制可具有下列益处:显示器200的较低功率使用或消耗,并且还可减少显示器200用户对正当NFC活动的潜在干扰,如读取授权NFC标签214。可用于触发NFC安全扫描活动的参数可包括但不限于,时间、传感器状态、显示器状态、或外部请求。时间参数的实例包括但不限于,定期间隔、每天固定时间、或另一参数的条件状态改变后的定时间隔。传感器状态的实例包括但不限于,红外、声音、接近、和振动传感器、以及环境传感器如光、温度和湿度。显示器状态的实例可包括但不限于,用户NFC询问活动或已经安装新授权NFC标签214后即刻的初始化。外部请求的实例可包括但不限于,通过诸如蓝牙、NFC或Wi-Fi的与网络控制器320关联的无线通信方法以及来自连接如Ethernet连接的有线通信传送的信号和通信。
触发扫描活动的条件可进一步是参数触发和状态以及选通(gating)此前触发活动的顺序条件的任何逻辑或期望的组合。例如,安全系统300可在白天以定期间隔实施扫描,此时显示器200顶部的光传感器被顶部荧光灯触发。在另一示例性实施方式中,安全系统300可在显示器200前方的声音传感器已被触发后的指定时间间隔后扫描显示器。在又一示例性实施方式中,安全扫描可在用户询问授权NFC标签204时被触发。
还参考示例性图2和示例性图3,如果安全系统300在实施扫描后检测到非授权NFC标签204或损坏的授权NFC标签214,则NFC安全系统300可选择所要实施的适当的动作或动作组并将其实施。系统300实施的安全动作可以是任何类型的动作,例如下列范围:直接对非授权标签204实施的动作至尝试减轻非授权标签204导致的威胁的逐步地更间接的动作。例如,可期望先尝试直接动作,而执行间接动作作为冗余和备用。
对非授权标签204的直接动作的实例可包括检查存储器内容和操作状态,发送指令以禁用标签204,重新编程标签204的存储器内容,或干扰所述标签204的通信通道。检查非授权标签204的存储器内容和状态可确定安全侵犯的威胁水平和严重程度。检查还可有助于确定包含可利用用户装置软件的缺陷的代码或包含在用户装置上安装恶意软件的指示器的非授权NFC标签。非授权标签204的存储器内容可被安全系统记录,用于稍后授权人员分析。禁用非授权标签204可通过已知和已建立的通常可用于NFC标签的指令如常用于隐私功能的“杀死”指令实现。干扰通信通道可通过下列方法实施:如发送读取指令至非授权标签203或传输随机噪声或脉冲,以中断与非授权标签204的通信。
间接安全动作的其他实例可包括警告授权人员,警示用户,或禁用显示器200。警告授权人员可通过可用于安全系统的无线或有线网络通信通道实现,例如通过网络控制器320。如果网络连接不可用于安全系统,可通过重新编程授权NFC标签214传送编码讯息。在这种实例中,信息可被嵌入URL指示器,该URL指示器传送编码讯息至网站服务器但不影响用户将在其能够NFC的装置上看见的网站内容。另一示例性信号传导方法可通过下列实现:在安全系统300的存储器中存储警报,以在授权人员维护间隔期间进行通信。视觉显示器如照明指示器可用于请求授权人员维护。这种指示器可被提供于显示器200上或周围,框架202上,海报206上或关联于海报,或作为指示器216的部分。类似地,对用户的警告可通过下列实现:通过听觉或视觉指示灯,或通过重新编程授权NFC标签214,以指示显示器200的问题。禁用显示器200也可通过下列实现:重新编程授权NFC标签214,结合关闭显示器200背光,以指示无功能状态。
在一些其他示例性实施方式中,NFC安全系统300可询问目标和授权NFC标签214,以检查存储器内容和识别码是否保持未损坏。授权NFC标签214中此前存储的唯一识别码和已知的良好数据可在授权人员将授权标签214安装到显示器200的期间被建立。如果安全系统确定授权NFC标签214无功能或具有损坏的存储器内容,则可执行类似于前述非授权标签204动作的动作组。
在进一步的示例性实施方式中,整合的RFID询问器系统,如NFC控制器322,可验证属于授权NFC标签214的唯一识别码和存储器内容。然后可将授权NFC标签214的唯一识别码和存储器内容与此前存储的已知的良好数据进行比较。如果在授权NFC标签214中检测到损坏的数据,则整合的RFID读取器(例如,NFC控制器322)可开始反复发送标签读取内容至授权NFC标签214。这种反复的标签读取内容可堵塞通信通道并阻止用户的能够NFC的装置询问授权NFC标签214。另外,可关闭显示器200背光,或提供发出显示器200不再发挥功能的信号的一些其他指示器。显示器200可在该问题被纠正后恢复正常使用和表现。
在另一示例性实施方式中,NFC安全系统300可通过蜂窝网络连接或其他期望的通信方法向互联网服务器报告非授权NFC标签204的存在。这种报告可利用网络控制器320传送。然后非授权标签(一个或多个)204的存储器内容可利用网络控制器320上传至服务器,用于稍后分析。还可通过来自服务器或直接来自网络控制器320的讯息警告授权人员非授权标签204的本质。
在又一示例性实施方式中,非授权NFC标签204的检测可通过整合的RFID询问系统——如具有NFC控制器322——进行。如前所讨论,安全系统的天线218可包围显示器200的外周,例如在框架202内,从而保护显示器200的整个表面和显示器200周围的区域。NFC控制器322可执行NFC(或RFID,如需)盘点功能,以检查非授权标签204的存在。盘点功能可确定激发天线线圈218附近的NFC标签204的数量和识别码。在检测到非授权标签204后,安全系统300可通过读取标签的唯一识别码和对非授权标签204执行杀死功能来禁用非授权标签204,如前文示例性实施方式所述。
在又一示例性实施方式中,安全系统300可包括可扫描13.56 MHz频带的RF能量的局部发射的RF或NFC无线电检测系统。这种扫描可通过利用NFC控制器322、RFID控制器或具有期望的扫描或询问能力的任何其他组件来实现。然后系统可比较在指定信号强度以上的发射检测与目标和授权标签214的询问定时。然后可通过安全系统300分析RF或NFC发射,以确定接近显示器200的用户是否正在读取非授权标签204。然后可利用关于发射的存在和性质的统计信息警告维护人员可能存在非授权标签204。
前文描述和附图示例本发明的原理、优选实施方式和操作方式。但是,本发明不应被解释为受限于上述具体实施方式。上述实施方式的另外改动将被本领域技术人员理解。
因此,上述实施方式应被认为是示例性的,而非限制性的。因此,应理解,本领域技术人员可对那些实施方式进行改动,而没有脱离所附权利要求限定的本发明范围。
