| 释义 | signature analysis 特征分析法;签名分析法 1. A technique for data compression, in which the entire data record is compacted into one or more hexadecimal words through an algorithm that weights each bit equally.For all practical purposes, this signature is unique to the data and may be compared to a known good signature. 一种数据压缩技术,整个数据记录经一种算法压缩成一个或多个十六进制字,该算法同等 地对每一位加权。实用上,该特征对于该数据是唯一的,并可以同某一已知的特征相比较。 2. A way of isolating digital logical faults at the component level. Although considered most useful in servicing microprocessor based products, the technique is applicable to all digital systems. It involves the tracing of signals and the conversion of lengthy bit streams into fourdigit hexadecimal signatures. 将数字逻辑故障隔离到元件级的一种方法。这种方法不但是以微处理机为基础的产品最 有用的服务手段,还适用于所有的数字系统。它包括信号的跟踪和将繁长的二进制信息 流转换成4位一组的十六进制(字符)特征。 3. In computer security and data security, a means of identification using written signatures for access control or authority to initiate a transaction. The automatic verification of signatures is based not only upon the shape of the completed signature, but also upon the dynamics of signature production (e.g. pressure deviation, acceleration, time or complete segments).The signature is normally input with an electronic pen, and measurements derived from the input are compared with prestored values appertaining to the purposed signature owner. 在计算机安全学和数据保密学中,一种鉴定签名的方法,用作存取控制和发起事务权限。 这种签名的自动核实不仅基于签名的整个外形,而且基于其动态特性(如压力偏差、加速 度、分段完成时间)。签名通常由电子笔输入,从输入中得到的测量结果与事先存储的相 关签名者的数值进行比较。 |
