Greyware
Greyware refers to a malicious software or code that is considered to fall in the “grey area” between normal software and a virus. Greyware is a term for which all other malicious or annoying software such as adware, spyware, trackware, and other malicious shareware fall under.
Brain Fingerprinting
Brain fingerprinting is a controversial technique that is advocated as a way to identify a terrorist or other dangerous person by measuring the “brainprint” of that person when shown a particular body of writing or an image that was previously familiar (such as of a training camp or manual). The brainprint is based on the P300 complex, a series of well-known brainwave components that can be measured. The technique is said to be more effective than a lie detector test.
灰件
灰件是指位于正常软件和病毒之间“灰色地带”的恶意软件或代码。灰件这个术语包括诸如广告件、间谍件、跟踪件等（病毒以外的）恶意或烦人的软件以及其他恶意的共享件等。
脑指纹
脑指纹是一项有争议的技术，被鼓吹用作识别恐怖分子或危险人物，它是通过向某人显示他熟悉的特别文章或图像（如训练营或手册上的内容）时测量他的“脑纹”。脑纹是基于P300复合体，即一系列著名的、可以测量的脑波成分。据说，该技术比测谎仪测试更有效。
