Description

以非接触状态进行充电的身份认证装置及其方法
技术领域
本案系指一种身份认证装置及其方法，特别是指一种以非接触状态对具 有内建电池的身份认证装置的充电方法。 背景技术
随着诈骗行为层出不穷且手法不断翻新，越来越多的场合要求在第一组 身份认证外尚须第二组身份认证，以确认使用者的正确身份。不论银行交易、 网路登入或一般门禁管理， 严密正确的身份认证已成为安全的第一道关卡。
目前的身份证明文件， 不论是身份证或驾照， 都仅能被动证明使用者的 身份， 虽然有先进的防伪技术, 亦仅能防止被伪造或被破坏 , 而没有主动证 明使用者即时无误的功能。
有效的即时身份认证技术应做到无法被复制、修改与破解， 目前常用到 的方法包括提供使用者一组随机产生的动态密码确认身份，使用者持有内建 无线射频元件的身份认证装置以证明其身份，或扫瞄使用者的指纹或虹膜等 生物特征确认身份。
以上方法都面临一个基本问题， 就是这些装置都需要以电力驱动元件， 目前的设计普遍以一小型一次电池（非充电电池）提供电力， 由于这些装置 必须做成轻薄短小， 方便使用， 故电池常不易更换， 且部分装置根本无法更 换电池， 故能提供的电力极为有限。 又因这些装置成本偏高， 电力耗尽就更 换装置不但不符合经济要求， 也增加身份证明装置被破坏的机会与风险。 因 此如何提供这些装置有效持久的电力， 便成为一项迫切需要解决的问题。
现行为一装置充电的技术，除了将充电装置的金属电极与被充电装置的 金属电极互相接触，对被充电装置进行接触状态的蓄电外， 还有以非接触状 态进行充电的技术。
目前， 有两种以非接触状态对被充电装置进行充电的技术： 电磁感应 ( electromagnetic induction ) 以及无线射频 ( radio frequency ) 。 电磁感应的原理为： 充电装置内的感应线圈首先产生感应磁场与电磁 能，被充电装置上的感应线圈进一步接收电磁场，将电磁能转换为电能储存 在被充电装置的电池内， 完成充电。 目前该技术已被应用于电动牙刷充电， 未来也有可能对移动电话、 个人数字助理（ personal digital assistant )等装置 进行充电。
无线射频技术以无线频率进行资讯的传递，理论上也可以经过调变解码 技术， 将电力通过无线频率由一个装置传给另一个装置， 使达到充电目的， 此一技术因效率过低， 尚未见于实际应用。
目前尚未有以非接触感应技术为身份认证装置提供电力的应用，如能做 到这一步，身份认证装置将可及时无误辨识及降低防止被伪造或被破坏的机 会， 延长身份认证装置使用寿命， 减少因失去电力而需经常更换的花费。
职是之故，申请人鉴于已知技术中所产生的缺失，乃经悉心试验与研究， 并一本锲而不舍的精神， 终构思出本案 "以非接触状态进行充电的身份认证 系统及其方法" ， 以下为本案的简要说明。

请继续参阅图 2, 电池 301为一可充电电池， 其中较佳的为一锂电池。 选用可充电电池可以克服需经常更换电池 301 的问题， 减少身份认证装置 30被破坏的机会与风险及降低装置成本。 电池 301依照身份认证装置 30的 外观及内部配置所需， 制作为包括但不限定为薄片或一长方体等。
请继续参阅图 2, 电磁感应元件 304为一电磁感应线圈与一无线射频元 件其中之一， 但相对应的充电装置（未显示于图 2 )需选用与电磁感应元件 304相同的电磁感应线圈或无线射频元件， 方能产生非接触的电磁感应。 而 适用于非接触的电磁感应的频率范围包括低频率、 高频率、超高频率或是微 波其中之一。 荧幕 305用以显示控制单元 302产生的资讯，使用者利用显示 的资讯进行身份认证与判读。通常，荧幕 305较佳的为一平面可挠式显示器， 因为其具有体积小、可耐外力扭曲的优点。键盘 306与控制单元 302电连接， 用以输入一指令至身份认证装置 30, 键盘 306至少有一按钮。 分流分压电 路 303可与一保护线路 307电连接， 用以保护身份认证装置 30在进行充电 时， 不会造成身份认证装置 30的损坏。 指示灯 308与控制单元 302电连接， 用以显示电池 301的电力及充电状态，指示灯 308的灯源通常为一发光二极 管， 因为发光二极管具有耗电低、 不含汞及寿命长的优点。 使用者按下键盘 306, 由指示灯 308显示的颜色得知电池 301的电力， 决定是否需将身份认 证装置 30进行充电。
本发明的身份认证装置（ 10、 30 )适用于各种需要电力的身份认证装置， 造型不拘， 包括但不限于手持电子装置、 卡片、 标签、 吊牌、 纸册等。
请参阅图 3 , 为本发明所提供的身份认证装置及充电装置的配置图。 在 图 3中， 身份认证装置 40包含一第一电源 401、 一分流分压电路 402及一 第一电磁感应元件 403 , 充电装置 50包含一第二电源 501及一第二电磁感 应元件 503 , 其中该第一电磁感应元件 403所产生的一第一频率与该第二电 磁感应元件 503所产生的一第二频率相同。
请继续参阅图 4, 为本发明所提供的身份认证系统的充电方法 60的方 块图。参照图 3的身份认证装置 40及充电装置 50的配置图与图 4的身份认 证系统的充电方法的方块图可以得知，当充电装置 50对身份认证装置 40进 行充电时， 包含下列步骤： （a )耦合第一频率与第二频率（步骤 601 ) ； ( b )转换该第二电源 501的一电力为该第二电磁感应元件 503的一电磁能 (步驟 602 ) ； ( c )传输该第二电磁感应元件 503 的该电磁能至该第一电 磁感应元件 403 (步骤 603 )； ( d )转换该第一电磁感应元件 403的该电磁 能为该电力并传输至该分流分压电路 402 (步骤 604 )； 和（ e )提供该电力 至该第一电源 401 (步骤 605 ) 。
其中， 步骤（a ) 的第一与第二频率需相同才能进行充电动作， 反之， 充电动作不会进行。 此外， 步骤（b )与步驟（c ) 中电磁能自第二电磁感应 W 200 元件 503传输至第一电磁感应元件 501是通过非接触的电磁感应，但身份认 证装置 40与充电装置 50的最小距离为零，最大距离为该电磁感应的磁场范 围的极限， 超过最大距离会发生感应不良或是无法进行充电。
步骤（e ) 中， 该分流分压电路 402所提供的电力包含一全部电力与一 部分电力其中之一。 当充电装置 50对身份认证装置 40进行充电， 且身份认 证装置 40并无进行身份认证时， 分流分压电路 402提供全部电力至第一电 源 401。 当充电装置 50对身份认证装置 40进行充电， 且身份认证装置 40 同时进行身份认证时， 分流分压电路 402提供部分电力至第一电源 401 , 另 提供部分电力供身份认证装置 40使用。
步骤（e ) 中， 分流分压电路 402所提供的电力， 其电压值应等于或高 于第一电源的额定电压，其单位时间电流值应等于或小于第一电源的额定电 容量， 确保充电有效且安全进行。
请继续参阅图 4, 本发明的身份认证装置的充电方法可适用于将至少一 身份认证装置 40同时放置于与充电装置 50发生电磁感应而产生的一电磁感 应磁场范围内进行充电。此优点在于使用者可以一次完成多个身份认证装置 40的充电动作、 节省充电装置 50的购置费用、 放置空间及线路配置。
如以上的发明可知， 利用本发明的身份认证装置， 以非接触状态对具有 内建电池的身份认证装置进行充电，可以彻底解决身份认证装置的电力供应 问题， 使身份认证装置能长期使用， 不受电力不足的限制。
本发明可以由本领域技术人员做任何修改，但不脱离如所附权利要求所 要保护的范围。
