Iris recognition relies upon the fact that every individuals retina has a unique structure. The iris landscape is composed of a corona, crypts, filaments, freckles, pits radial furrows and striatations. Iris scanning is considered a particularly accurate identification technology because the characteristics of the iris do not change during a persons lifetime, and because there are several hundred variables in an iris which can be measured. In addition, iris scanning is fast: it does not take longer than one or two seconds.
These are characteristics which have made iris scanning an attractive technology for high-security applications such as prison surveillance. Iris technology is also used for online identification where it can substitute identification by password. As in other biometric technologies, the use of iris scanning for the protection of privacy is a two-edged sword. The prevention of identity theft applies horizontally but not vertically, i.e. in so far as the data retrieval that accompanies identification and the data body which is created in the process has nothing to do with identity theft.

In biometric technology, the subject is reduced to its physical and therefore inseparable properties. The subject is a subject in so far as it is objectified; that is, in so far as is identified with its own res extensa, Descartes' "extended thing". The subject exists in so far as it can be objectified, if it resists the objectification that comes with measurement, it is rejected or punished. Biometrics therefore provides the ultimate tool for control; in it, the dream of hermetic identity control seems to become a reality, a modern technological reconstruction of traditional identification techniques such as the handshake or the look into somebody's eyes.
The use of identification by states and other institutions of authority is evidently not simply a modern phenomenon. The ancient Babylonians and Chinese already made use of finger printing on clay to identify authors of documents, while the Romans already systematically compared handwritings.
Body measurement has long been used by the military. One of the first measures after entering the military is the identification and appropriation of the body measurements of a soldier. These measurements are filed and combined with other data and make up what today we would call the soldier's data body. With his data body being in possession of the authority, a soldier is no longer able freely socialise and is instead dependent on the disciplinary structure of the military institution. The soldier's social being in the world is defined by the military institution.
However, the military and civilian spheres of modern societies are no longer distinct entities. The very ambivalence of advanced technology (dual use technologies) has meant that "good" and "bad" uses of technology can no longer be clearly distinguished. The measurement of physical properties and the creation of data bodies in therefore no longer a military prerogative, it has become diffused into all areas of modern societies.
If the emancipatory potential of weak identities is to be of use, it is therefore necessary to know how biometric technologies work and what uses they are put to.

Other biometric technologies not specified here include ear recognition, signature dynamics, key stroke dynamics, vein pattern recognition, retinal scan, body odour recognition, and DNA recognition. These are technologies which are either in early stages of development or used in highly specialised and limited contexts.

In order to be able to recognize a person, one commonly looks at this persons face, for it is there where the visual features which distinguish one person from another are concentrated. Eyes in particular seem to tell a story not only about who somebody is, but also about how that persons feel, where his / her attention is directed, etc. People who do not want to show who they are or what is going on inside of them must mask themselves. Consequently, face recognition is a kind of electronic unmasking.
"Real" face-to-face communication is a two-way process. Looking at somebody's face means exposing ones own face and allowing the other to look at oneself. It is a mutual process which is only suspended in extraordinary and voyeuristic situations. Looking at somebody without being looked at places the person who is visually exposed in a vulnerable position vis-à-vis the watcher.
In face recognition this extraordinary situation is normal. Looking at the machine, you only see yourself looking at the machine. Face biometrics are extracted anonymously and painlessly by a mask without a face.
Therefore the resistance against the mass appropriation of biometrical data through surveillance cameras is confronted with particular difficulties. The surveillance structure is largely invisible, it is not evident what the function of a particular camera is, nor whether it is connected to a face recognition system.
