防窥视乱序密码输入器
技术领域
本发明涉及键盘输入装置， 具体是一种实用于金融、 证券、 商业、 邮政、 电信等领域， 釆用密码进行个人身份识别或使用键盘作为信息录入工具又必 须防窥视的一防窥视乱序密码输入器。
技术背景
随着电子商务的普及， 网络银行、 自助银行迅猛发展， 持卡消费也逐渐 深入各行各业， 密码键盘， P0S机和 ATM机的使用也更加广泛。
釆用密码进行个人身份的识别是目前通用的方法。
当人们在公共场所使用密码输入器输入密码时， 很容易被他人窥视而造 成泄密。 近些年发生在金融证券业， 客户密码被窃， 资金被盗取的案件呈上 升趋势， 而目前普遍使用的是数字位固定的密码输入器， 当使用者在输入密 码时， 不法分子往往在使用者的旁边、 背后或在远处利用器械偷窥等方式窃 取使用者的密码， 克隆银行卡折， 给国家、 集体和个人的财产造成了严重的 损失, 也直接影响了金融证券业的声誉。
发明内容
本发明的目的是提供一种按键釆用凸透镜成像及视角差原理和按键键值 0- 由控制电路随机产生的乱序排列方式进行设计的防窥视乱序密码输入 器。
本发明釆用的技术方案是这样的： 一种防窥视乱序密码输入器， 包括由 按键构成的键盘及按键控制的密码输入电路和按键键值 0— 9数字位随机组合 排列控制电路的主电路板； 其中按键键值 0— 9数字位随机组合排列控制电路

确认本 包括 C )、 数据存储器、 译码器电路、 显示驱动电路和数码显示电路； CPU的 输出端通过接口转换电路与串行通讯口连接， 通过译码器电路及显示驱动电 路和显示器连接， 通过语音提示电路与功放电路连接； 其特征是： 键盘上的 按键由透明体或凸透镜及固定在一起的非透明体边框构成； 其中非透明体边 框底部的按键脚与其下方的开关板上对应按键脚位上具的有的微动开关或薄 膜开关弹性接触； 开关板对应透明体或凸透镜部位开孔， 开孔的下方为固定 在主板上的字符显示载体， 构成键盘矩阵的所述微动开关或薄膜开关的输出 端与主电路板上的 CPU的输入端连接构成密码输入电路。 另外按键键值 0— 9 数字位随机组合排列控制电路釆用 CPU控制的按键键值 0— 9 随机产生乱序 码， 由字符显示载体显示， 键值的位置不固定， 组合变化多， 重复率低。
本发明的优点是很明显的， 即由于本发明是采用凸透镜成像及视角差原 理设计的按键， 使用时， 要输入密码， 只能在一定的视角内， 垂直正视键面， 才能通过透明体或凸透镜完整地看清楚按键下方字符显示载体显示的数字， 偏离一定的角度， 由于视角差或焦距的改变， 按键内显示的字符则呈现看不 全或看不见， 甚至只能看见因变形而无法辨认的字体， 因而确保了输入的密 码不会被他人窥视窃取。 此外， 本发明的控制电路采用 CPU控制的按键键值 0 一 9随机产生乱序码， 由.字符显示载体显示，键值的位置不固定，组合变化多， 重复率低， 杜绝了因记忆触键位置猜测密码， 从而更进一步地防止密码被窥 视窃取。

具体实施方案
参见附图， 在附图给出的一个非限定性的实施例中， 在键盘 7上的按键 1 具有由非透明材料制作的边框 a， 中间镶嵌有透明体或凸透镜体 b 的视窗部 分； 其透明体或凸透镜下表面至字符载体 5的距离由螺栓 6定位， 其间隔距 离在 30隱左右或可视角度 < 80°, 以符合防窥视的要求。 字符显示载体 5与主 电路板 4连成一体。按键下方为在视窗对应处开孔的开关板 2, 开关板上装有 开关矩阵的微动开关或薄膜开关 3。 按键下压时， 按键脚 c按压相对应的开 关， 导通电路， 实现指令的输入。 开关板下方为主电路板 4, 板上装有与按键 视窗对应的字符显示载体 5, 为确保在任何环境下数字显示清楚、 醒目， 并且 容易辩识， 本例采用与主电路板连接成一体的数码管， 数码管显示的字体由 控制电路驱动， 随机排序。 为防窥视的要求， 确保适合的焦距和视角差， 视 窗到数码管的距离由固定螺栓 6定位， 并使键盘 7、 按键 1、 开关板 2、 主电 路板 4成为一个整体。 字符显示载体可以是印有字符的卡片。
图 2. 3. 4. 5 所示， 主电路板上的控制电路包括 CPU (U2) ,实施中， U2釆用 AT89CC52, 键值随机排序程序也烧录在 CPU内； 具有 14个按键的键盘 K ( 7 ), 具有译码电路 实施中， 采用 74LS145构成的译码器电路， 显示驱动电路 U3采用 MC1413,实施中 T1-T10采用三极管 9012构成的字符显示载体驱动电 路。 显示驱动电路的输出端分别与字符显示载体的各控制端连接， 实现字符 的显示。 CPU ( U2 ) 的串行通讯端 RXD和 TXD接至串行通讯转换电路实现与外 部连接的终端机或 PC机进行数据传输。
按键键值 G— 9数字位随机排序的实现， 是由烧录在 U2内的乱序程序产生 的随机码组合而成， 由于特定的乱序运算， 随机产生的键值 Q— 9排列组合各 不相同， 无规律可寻。
当 U2检测到终端机或 PC机发出输入密码指令， U2立即随机产生一组 0— 9 键值码， 发送至译码器 U1又经码器 至显示驱动电路 T1一 T10, 驱动显示载 体显示， 当使用者按照字符显示载体显示的键值进行密码输入操作时， U2会根 据键盘矩阵 K记录的键值予以记录， 密码输入搡作完毕， 经确认后， U2将记录 的密码通过通讯接口传输至终端机或 PC机。 此时， 本发明又处于等待状态， 至下一个操作周期。
