Hallo OM
Hier habe ich ein paar Informationen
der amerikanischen AIM ueber RFID und moechte sie
gerne zitieren. Ich habe sie im englischen Orginal
gelassen. Der Text ist mit Vorsicht zu genissen
und enthaelt nicht ausschliesslich technische Informationen
ueber das RFID Funksystem. Klaert aber viele Fragen
der Intention.
----------------------------------------------------------
Can or will governments implement an RFID tracking system to
know where each citizen is at any time?
The infrastructure costs for a government entity to track
all citizens would be astronomical, not to mention the
tremendously large data base that would be generated as
people pass from point to point. The practicality of such
an application is well beyond any government's capability
to afford the infrastructure and data management issues,
let alone the thought of consumers allowing this type
of tracking to take place.
Currently, a court subpoena is required to use
private information such as cell phone records and credit
card purchases. This information is strictly for use in
criminal activities investigations. The data generated from
the use of RFID should be private and proprietary and
include the same protections on privacy that are currently
in place.
(Das ist nur fiktive Behauptung und aller Erfahrungen zum Trotz
Jeder Platz der mit Video-Kamera ausgeruestet werden kann,
kann ebenso mit einer RFID Schranke bestueckt werden.
Wo ueber die Biometrische Erkennung nachgedacht wird,
kann leicht auch mit RFID aufgeruestet werden.
Es reicht einen 5 Cent RFID Chip in den Pass zu drucken.
Und die Datenmenge ist im Vergleich zu allen gespeicherten
Telefonverbingungen der Telekom, Internetproviderzugaengen
usw. locker von einem kleinen Computercluster zu bewerkstelligen.)
What are some of the more established uses?
Your automobile almost certainly has an immobilizer to prevent
it from being stolen. It has been ten years since the Ford Motor
Company first introduced an RFID immobilizer and such systems
are common in vehicles manufactured by the other major manufacturers.
RFID has also been used extensively in toll collection, inventory
control, building security, and library systems.
Could I be tracked by my car keys?
No. The transponders used in the latest models have a very
short reading range
(typically a few inches) and use encryption between the key
and the reader. During manufacture of the vehicle, the
engine management computer generates a different random
number (that is, the secret key for encryption) for each and
every key. Unless that secret number is known, the vehicle
key will not respond. In addition, the reader would have to
be within inches of the key to give the key enough energy to
even work.
What’s the typical read range for RFID devices?
The majority of RFID transponders have a read range
of less than 3 feet.
Some applications, limit the read range to around 6 to 8
inches. Some newer technologies (UHF systems) do have a
longer read range that can be 20 to 25 feet, but these
systems are intended for pallets and shipping crates.
(Sorry Leute, gehen nicht auch Autoschluessel? s.o.
Oder Maut-Stellen?)
Read range depends on many factors, but the size of the
transponder’s antenna, the size of the reader’s antenna and
its output power are the main ones. With battery-less
transponders, long read range and small size are mutually
exclusive.
Are there any broadcast power restrictions set forth by
governmental regulations?
Yes, the FCC in the US and other
governing bodies worldwide restrict the output power of RFID
systems. It is illegal to exceed these limits, and in most
countries it is a condition of sale that the equipment meets
these requirements. In addition, the frequencies themselves
at which RFID systems operate are regulated.
(Gibt es diese Regulation auch in EU/DL? Und wer kontrolliert?)
Are there any health concerns/dangers caused by proximity to
or wearing clothing containing RFID tags?
Passive RFID tags do not actually radiate RF energy,
but simply reflects it. It would not add to any RF energy
already in the environment.
(Ziemlicher Wiederspruch! Warum gibt die FCC dann
"Power Regulations" heraus? s.o. Die Lesegaeraete senden
doch aktiv. Also wird es auch unter EMVU Regeln fallen?
Der Text ist schlau nur auf die passiven RFID Tags hin formuliert
die aktive Sendetechnik wird dabei aussen vor gelassen.
Wieviel Power darf denn so ein RFID Lesegeraet abstrahlen?)
Is it true that there are safeguards in place that protect
from "eavesdropping" or intercepting data that is private?
Efforts are being made to protect consumer privacy by
securing information at all levels of data exchange. Secure
computer systems form the foundation of this security,
leaving RFID to be deployed with similar degrees of
security. A major difference between RFID and say magnetic
stripe technology (as is used on bank cards) is operability
over the air. The risk of eavesdropping or intercepting
transmitted data is well recognized, as is the risk of
someone using a concealed reader. Both of these risks are
greatly reduced through the design of appropriate over-the-
air protocols and data encryption methods. This protocol
requires the tag to be within range of both the reader and
the eavesdropper. In addition, the reader changes frequency
rapidly and the eavesdropping reader must follow the main
reader exactly. This is very difficult since the hopping
sequence is random. Then there is the data encryption
algorithm codes that must be cracked in order to use the
data. A well designed system will protect consumers by
implementing the proper protocol to achieve a level of
security comparable and even beyond more mature
technologies.
(Schoen das die Entwickler von vornherein das Gefuehl
haben das die missbraeuchliche RFID Anwendung zum Chaos
fuehren koennte. Denn nicht der Kunde soll geschuetzt werden
sondern wohl das Erfassungsystem.)
Can RFID Tags be duplicated?
Yes it is possible, but very unlikely.
The technological hurdle is intentionally very
high, making it impractical in virtually all cases.
Counterfeiting of tags is also detectable by the systems
used to read tags and verify authenticity through a variety
of validation procedures. One such validation procedure is
to check for records of copies having been previously used.
More elaborate schemes involve secure challenge and response
protocols involving secret numbers used as encryption keys.

What are RFID manufacturers within AIM doing in order to
clarify the privacy issues?
Education about the capabilities and the limitations of
the technology is of the utmost importance to AIM and
its member companies. AIM is committed
to providing information that will clarify some of the
statements and myths that are being propagated by sources
not familiar with RFID technology. As with any new
technology, people must become comfortable with RFID and
understand the many benefits of the technology for
consumers. It therefore is important to ensure that
consumers are educated about the technology so that a good
understanding of the practical use of RFID and how it
differs from the theoretical use. What’s possible is a far
cry from what is practical in the use of RFID.
(Auf diese EDUCATION bin ich ja mal gespannt.
Wenn diese EDUCATION so aussieht wie diese Informationen hier,
dann vermute ich eine gross angelege Verbrauchermanipulation.)
What mechanisms can be used to allow consumers to "opt in"
or "opt out"?
RFID manufacturers *can*(!) build in a "kill"
mechanism that would permanently disable the tag at the
check-out counter should the consumer choose to do so. As
the adoption of EPC technology moves forward it will be
important to have these things standardized. In current
loyalty programs, consumers that opt in enjoy benefits,
while those who choose not to participate do not enjoy the
benefits. Today, most loyalty programs use bar codes, which
most consumers are comfortable with. The important point is
that the consumer has a choice whether to join or not.
(Bitte beachten, das ein "can" dort steht, nicht "must")
Can RFID tags be read by satellites in orbit?
No. That is not practical nor possible based on the
short read ranges and the huge amount of power that
would be required to broadcast from a satellite in order
to pick up information on an RFID tag.
(Doch! Genau Diese bietet eine amerikanische Firma fuer
"medizinische" Kontrollueberwachung an. Dazu wird z.Zt. noch ein
zusaetzlicher Transponder in der groesse eines Handfunkgeraetes
benoetigt. Die RFID Tags koennen dann sogar vom Probanden
geschluckt werden. Die Internet URL mit der Beschreibung
der RFID-Satellit Technologie werde ich bei Gelegenheit
nachliefern.)
Is RFID a true threat to consumer privacy?
AIM is an advocate for responsible use of the RFID technology.
AIM *believes*(!) that RFID presents no more of a threat to
individual privacy than the use of cell phones, toll tags,
credit cards, the use of ATM machines, and access control
badges. All of these examples allow consumer conveniences or
provide protection for consumers.
(So, so daran "glaubt" die AIM also, interessanter Glaube dem
ich mich aber nicht anschliessen muss.)
Can other retailers read RFID tags on your clothing as you
enter or exit a store?
Since there are no current applications of this nature
in operation, the answer is "no."
In the future, retailers that use RFID will build in
safeguards to prevent this, not only for the protection of
the consumer's privacy, but for the protection of the
retailer. Even if a retailer was able to capture another
retailer's data from an RFID tag, the data would be useless
because of encryption and other security mechanisms
retailers would build in to protect consumer privacy and the
retailer's data.

-----------------------------------------------------------
Das sind bisher typische "Verbraucher" Informationen die man
zu dem RFID Funksystem aus erster Hand erhaelt. Ich habe
darauf verzichtet weitere "Beschoenigungen" zu zitieren und
weiterzugeben, weil sie ziemlich irrefuehrend sind
und mit der Technologie hinter dem Berg haelt.
Wenn man oben genanntes genau liest, kann man schlussfolgern
das alles, was zur Zeit mit der RFID Technologie noch nicht
machbar oder zu teuer ist, gerne gemacht werden wuerde.
Ich finde die RFID Technologie faszinierend, weil sie
mit einem unheimlich grossen Informationsvorsprung im
heimlich verborgenen arbeiten kann, ohne das jemand etwas
davon bemerken muss. Clever.
Gruss Christoph
