生物计量学（biometrics，也称生物测定学Biostatistics)
就目前在应用领域上来看，大多资料上用的还是Biometrics这个单词。

Biometrics所涉及的主要领域也比较广泛，主要有以下几个类别：
1、医学生物测定学
2、生态群系类的生物测定学（生态群系信息的大规模采集和处理，以建立安全可靠的生态群系数据）
3、人体生物测定学
物理测定：包括指纹、虹膜检测等
行为测定：签名、声波（voiceprint），步态以及一些特殊习惯动作的监测等
化学测定：DNA、体味等。
目前，应用和发展比较热门的有指纹识别、生物证明等，这些技术主要应用于一些特殊领域和部门，比如政府身份识别项目以及消费类身份识别系统，主要是安全性的保障，而这是也Biometrics产业的主要增长动力。
指纹识别，是Biometrics目前应用最广泛的技术。主要用于司法领域的自动指纹识别系统与现场扫描系统（AFIS/Live-Scan）将占到2007年市场总额的33.6%，用于访问控制领域的指纹识别系统占25.3%。

其他技术所占份额包括：面部识别12.9%，虹膜识别5.1%，声音识别3.2%。静脉识别仅占3.0%，但在访问控制市场将有较大的增长潜力。
生物证明，Biometrics的一个应用，是指测量人的物理特性实践核实他们的身分。通过运用生物统计系统，来测量指印或递印刷品，目前更加先进的生物统计的系统测量用户用户眼睛的声音、特点, 或他们的整个面孔几何。未来派系统测量用户耳朵、他们的气味, 甚至他们的DNA 。
当然也有应用于其他领域的Biometrics技术，比如Oregon State University 有个Forest Biometrics专业，是在Forest Biometrics Department 里的一个专业，研究森林的种植生长以及产出等，大量运用统计学来采集相关信息做精确测量，并提出改进方法、提出更高的管理手段。

Biometrics are the main areas involved in more extensive, mainly in the following categories:
1, the medical biometrics
2, ecological formations like biometrics (ecological formation of large-scale collection and processing of information to establish secure and reliable data on the ecological formations)
3, human biometrics
Physical Measurement: including fingerprints, iris detection
Biometrics (also known as Biostatistics)
For now the applications point of view, most of the information on the use of the word or Biometrics.
Behavior determination: signature, acoustic (voiceprint), gait, and some special custom monitoring actions
Chemical determination: DNA, body odor, etc..
At present, the application and development of more popular with fingerprint recognition, bio-proof, these technologies are applied to specific areas and sectors, such as government ID projects, and consumer identification system, mainly security protection, which is also Biometrics industry's main growth engine.
二:
Fingerprint identification is the Biometrics currently the most widely used technology. Mainly used in the judicial field Automated Fingerprint Identification System and Live Scan System (AFIS / Live-Scan) will account for the total market in 2007 to 33.6%, for access control in the field of fingerprint identification system accounted for 25.3%. The share of other technologies, including: 12.9% facial recognition, iris recognition by 5.1%, 3.2% voice recognition. Vein identification only 3.0%, but in access control market will have greater growth potential.
Biological proof, Biometrics an application refers to the practice of measuring physical characteristics of people to verify their identity. Through the use of biometric systems to measure the fingerprints or delivery print, currently more advanced biometric systems that measure the user's voice users eyes, features, or their entire face geometry. Futuristic system measurements to the ear, their smell, even their DNA.

还是LZ,继续
Of course, there are used in other areas of Biometrics technology, such as Oregon State University has a Forest Biometrics professional, is in Forest Biometrics Department in a professional, the planting of forest growth and output, etc., extensive use of statistics to collect relevant information to do accurate measurement, and propose a new approach, proposed by higher management tool.

因为我的专业是计算机,所以我比较倾向于介绍和计算机有关的内容,比如,我的笔记本电脑上有一个指纹器,配合相应的软件,就可以实现很多功能.
它可以用指纹代替windows登录密码,可以用指纹代替向任何网站(hotmail,facebook)或者软件(msn)输入密码.而不用键盘来输入密码.这样不仅更加安全,而且更加简单快捷.
它还可以保护电子邮件，使客户在通过因特网传输时电子邮件不会被他人阅读或修改，只有正确的收件人才能阅读和回复信息。

Because my major is computer science, so I tend to introduce and computer-related content, for example, my laptop has a fingerprintreader, with the appropriate software, you can achieve a lot of features.
It can replace the windows with a fingerprint login password, you can use fingerprints instead of to any website (hotmail, facebook) or software (msn) for a password. Instead of the keyboard to enter a password. This will not only safer, but easier.
It also can protect e-mail to customers via the Internet, e-mail transmission can not be read or modified others, and only the correct recipient can read and reply to messages.

DNA 破案
DNA源自于Deoxyribonucleic Acid，即是脱氧核糖核酸，DNA查案技术，也称为遗传指纹技术。
它最奇特之处，就是类似人类手指指纹，每个人的DNA都是独一无二的，只有同卵双胞胎，才会拥有相同的DNA。
而且，DNA在协助破案时，比指纹更占优势的地方是，人体任何部分的细胞组织，都有DNA的踪迹，不像指纹只限于手指头。
每个细胞皆含DNA
在案发现场，若是逞凶者戴著手套办案，刑警很可能就没有办法找到手指指纹，从而加深破案难度。
DNA采集就不同了，逞凶者留下的丁点血迹、细微的皮屑如头皮屑、毛发、汗液、口水、精液等，都可以成为人在现场的证据，进而成为破案的关键，从几十亿人中识别出犯罪分子。

DNA detection
DNA derived from Deoxyribonucleic Acid, which is DNA, DNA crime detection technology, also known as genetic fingerprinting.
It is most unusual in the sense that like the human fingerprints, each person's DNA is unique, only identical twins will have the same DNA.
Moreover, DNA to help solve the case, the fingerprint is much more advantageous than the place is that any part of the body tissue, have traces of DNA, unlike fingerprints fingers only.
DNA of each cell, all in of them.
At the scene, if the perpetrator was wearing gloves in handling cases, Interpol may not find fingerprints on to enhance detection difficult.
DNA collection is different, the perpetrators left the little bit of blood, subtle, such as dandruff dander, hair, sweat, saliva, semen, etc., can become evidence in the scene and then became
the key to solving cases, from several billion Among the identified criminals.

指纹可以分为三类：

第一类是明显纹，就是目视即可见的纹路。如手沾油漆、血液、墨水等物品转印
而成，通常都是印在指纹卡上成为基本资料；

第二类是成型纹，这是指在柔软物质，如手接触压印在蜡烛、黏土上发现的指纹；

第三类是潜伏指纹，这类指纹是经身体自然分泌物如汗液，转移形成的指纹纹路，
目视不易发现，是案发现场中最常见的指纹。潜伏指纹往往是手指先接触到油脂、汗
液或尘埃后，再接触到干净的表面而留下，虽然肉眼无法看到这些指纹，但是经过特
别的方法及使用一些特别的化学试剂加以处理，即能显现出这些潜伏的指纹。

鉴识人员最常接触到的指纹是潜伏纹。如果指纹是留在金属、塑胶、
玻璃、磁砖等非吸水性物品的表面，检验方法就比较容易。通常可以用粉末法，选择
颜色对比大的粉末，撒在物品表面提取出完整的指纹；另一方法是磁粉法，以微细的
铁粉颗粒，用磁铁作为刷子，来回刷扫，显现指纹。

如果指纹留在纸张、卡片、皮革、木头等吸水性物品的表面，必须经过化学处理
才能在化验室显形。常用的化学法有：

碘熏法——即使用碘晶体加温产生蒸气，它与指纹残留物的油脂产生反应后，便
会出现黄棕色的指纹，必须立即拍照或用化学方法固定；

宁海得林（Ninhydrin)法——将试剂喷在检体上，与身体分泌物的氨基酸产生反
应后，会呈现出紫色的指纹；

硝酸银法——硝酸银溶液与潜伏指纹中的氨化钠产生反应后，在阳光下会产生黑
色的指纹；

萤光试剂法——萤光氨与邻苯二醛几乎马上与指纹残留物的蛋白质或氨基酸作用，
产生高萤光性指纹，此试剂可以用在彩色物品的表面。
