Biometrics applications: privacy issues

All biometric technologies capture biometric data from individuals. Once these date have been captured by a system, they can, in principle, be forwarded to other locations and put to many different uses which are capable of compromising on an individuals privacy.

Technically it is easy to match biometric data with other personal data stored in government or corporate files, and to come a step closer to the counter-utopia of the transparent citizen and customer whose data body is under outside control.

While biometric technologies are often portrayed as protectors of personal data and safeguards against identity theft, they can thus contribute to an advance in "Big Brother" technology.

The combination of personalised data files with biometric data would amount to an enormous control potential. While nobody in government and industry would admit to such intentions, leading data systems companies such as EDS (Electronic Data Systems; http://www.eds.com) are also suppliers of biometric systems to the intelligence agencies of government and industry.

Biometric technologies have the function of identification. Historically, identification has been a prerequisite for the exercise of power and serves as a protection only to those who are in no conflict with this power. If the digitalisation of the body by biometric technologies becomes as widespread as its proponents hope, a new electronic feudal system could be emerging, in which people are reduced to subjects dispossessed of their to their bodies, even if these, unlike in the previous one, are data bodies. Unlike the gatekeepers of medieval towns, wear no uniforms by they might be identified; biometric technologies are pure masks.

Copyright Management and Control Systems: Metering

Metering systems allow copyright owners to ensure payment to or at the time of a consumer's use of the work. Those technologies include:

Hardware Devices

Those have to be acquired and installed by the user. For example under a debit card approach, the user purchases a debit card that is pre-loaded with a certain amount of value. After installation, the debit card is debited automatically as the user consumes copyrighted works.

Digital Certificates

Hereby a certification authority issues to a user an electronic file that identifies the user as the owner of a public key. Those digital certificates, besides information on the identity of the holder can also include rights associated with a particular person. Vendors can so control access system resources, including copyrighted files, by making them available only to users who can provide a digital certificate with specified rights (e.g. access, use, downloading).

Centralized Computing

Under this approach all of the executables remain at the server. Each time the executable is used, the user's computer must establish contact with the server, allowing the central computer to meter access.

Access Codes

Access code devices permit users to "unlock" protective mechanisms (e.g. date bombs or functional limitations) embedded in copyrighted works. Copyright owners can meter the usage of their works, either by unlocking the intellectual property for a one-time license fee or by requiring periodic procurement of access codes.

Copyright Clearinghouses

Under this approach copyright owners would commission "clearinghouses" with the ability to license the use of their works. A user would pay a license fee to obtain rights concerning the intellectual property.

DES

The U.S. Data Encryption Standard (= DES) is the most widely used encryption algorithm, especially used for protection of financial transactions. It was developed by IBM in 1971. It is a symmetric-key cryptosystem. The DES algorithm uses a 56-bit encryption key, meaning that there are 72,057,594,037,927,936 possible keys.
