RSA Security has announced that it's
working on RSA Blocker Tag, an anti-radio frequency identification
technology. The proposed tag is designed to prevent readers from accurately
scanning tags on goods and reading their electronic product codes, or EPCs.
When development is complete, the blocker
tags will work by "spamming" RFID readers that attempt to scan tags. Blocker
tags will be active in the same short range as RFID tags, and must be in
close proximity to a tag in order to block it. RSA demonstrated a
software-based version of the blocker at its RSA Security conference.
The pharmaceutical industry is rapidly moving
toward item-level RFID tagging of products, while consumer packaged goods
manufacturers are testing pallet- or case-level tagging as they evaluate the
advantages of tracking individual high-priced items such as Gillette's Mach
2 razor blades.
"In a naive, RFID-enabled world without
technical forethought, there is risk that sensitive information could be
visible in secret to anyone with an RFID reader," Burt Kaliski, director and
chief scientist of RSA Laboratories, said in a statement. RSA is a founding
member of EPCglobal, an industry consortium developing standards for the
commercial use of RFID. It's the first technology company to openly admit
that RFID could be used to invade consumers' privacy.
"Whereas retailers think about tracking
inventory," Kaliski said, "privacy advocates worry about what happens when
the RFIDs leave the store. It's up to companies like RSA Security to help
bridge that gap."
Also on Tuesday, California State Senator
Debra Bowen introduced SB 1834, the first national bill to propose privacy
standards for the use of RFID. The activist Democratic senator from Redondo
Beach wants legislators to require businesses or government agencies to
inform people when they use an RFID system, get express consent before
tracking and collecting information and detach or destroy RFID tags that are
attached to a product before it leaves the store. Bowen chairs the Senate
Subcommittee on New Technologies, which held two hearings on RFID technology
and privacy.
Privacy activists say that neither killing
tags when a product leaves the store nor the availability of blocker tags is
enough. A recent position statement issued by Consumers Against Supermarket
Privacy Invasion and Numbering (CASPIAN) and seven other organizations
including the Privacy Rights Clearinghouse, American Civil Liberties Union
and Electronic Frontier Foundation said that killing tags at the store exit
doesn't solve the problem of tracking consumer behavior inside the store.
The group fears the availability of blocker tags might encourage the
proliferation of RFID by giving consumers a false sense of security.
