| 释义 | signature image system 签名映象系统 A system in which 2k to 4k bits of information can be stored on a disk subsystem for later retrieval. Processor that accepts requests for signatures, retrieves the stored data, and then transmits the compressed signature data to the correct CRT terminal, where it is displayed by the display subsystem. Often a signature request can be made via dialup lines just by entering such information as an account number or a credit card number into the keyboard of a terminal. Then, when the stored signature is displayed on the CRT screen, the operator can determine its validity by comparing the displayed signature with the signed document prepared by the customer. 一种系统,其中2k到4k位的信息储存在磁盘子系统中供后来检索用。处理机接受署名请求,检索存储数据,然后把压缩的署名数据传送到正确的CRT终端,由显示子系统显示出来。 署名请求常可通过电话拨号线路作出,就象用终端键盘输入一帐号或信用卡号那样。此后,当所存的署名显示在CRT屏幕上时,操作员把显示出来的署名与顾客的签字的文件上显 示的署名进行比较,就能判断其合法性。 |
