Radio Frequency Identification (RFID) is an item-tagging technology with profound societal implications. Used improperly, RFID has the potential to jeopardize consumer privacy, reduce or eliminate purchasing anonymity, and threaten civil liberties.

As organizations and individuals committed to the protection of privacy and civil liberties, we have come together to issue this statement on the deployment of RFID in the consumer environment. In the following pages, we describe the technology and its uses, define the risks, and discuss potential public policy approaches to mitigate the problems we raise.

RFID tags are tiny computer chips connected to miniature antennae that can be affixed to physical objects. In the most commonly touted applications of RFID, the microchip contains an Electronic Product Code (EPC) with sufficient capacity to provide unique identifiers for all items produced worldwide. When an RFID reader emits a radio signal, tags in the vicinity respond by transmitting their stored data to the reader. With passive (battery-less) RFID tags, read-range can vary from less than an inch to 20-30 feet, while active (self-powered) tags can have a much longer read range. Typically, the data is sent to a distributed computing system involved in, perhaps, supply chain management or inventory control.

THREATS TO PRIVACY AND CIVIL LIBERTIES

While there are beneficial uses of RFID, some attributes of the technology could be deployed in ways that threaten privacy and civil liberties:

  • Hidden placement of tags. RFID tags can be embedded into/onto objects and documents without the knowledge of the individual who obtains those items. As radio waves travel easily and silently through fabric, plastic, and other materials, it is possible to read RFID tags sewn into clothing or affixed to objects contained in purses, shopping bags, suitcases, and more.

  • Unique identifiers for all objects worldwide. The Electronic Product Code potentially enables every object on earth to have its own unique ID. The use of unique ID numbers could lead to the creation of a global item registration system in which every physical object is identified and linked to its purchaser or owner at the point of sale or transfer.

  • Massive data aggregation. RFID deployment requires the creation of massive databases containing unique tag data. These records could be linked with personal identifying data, especially as computer memory and processing capacities expand.

  • Hidden readers. Tags can be read from a distance, not restricted to line of sight, by readers that can be incorporated invisibly into nearly any environment where human beings or items congregate. RFID readers have already been experimentally embedded into floor tiles, woven into carpeting and floor mats, hidden in doorways, and seamlessly incorporated into retail shelving and counters, making it virtually impossible for a consumer to know when or if he or she was being "scanned."

  • Individual tracking and profiling. If personal identity were linked with unique RFID tag numbers, individuals could be profiled and tracked without their knowledge or consent. For example, a tag embedded in a shoe could serve as a de facto identifier for the person wearing it. Even if item-level information remains generic, identifying items people wear or carry could associate them with, for example, particular events like political rallies.

FRAMEWORK OF RFID RIGHTS AND RESPONSIBILITIES

This framework respects businesses' interest in tracking products in the supply chain, but emphasizes individuals' rights to not be tracked within stores and after products are purchased. To mitigate the potential harmful consequences of RFID to individuals and to society, we recommend a three-part framework. First, RFID must undergo a formal technology assessment, and RFID tags should not be affixed to individual consumer products until such assessment takes place. Second, RFID implementation must be guided by Principles of Fair Information Practice. Third, certain uses of RFID should be flatly prohibited.

Technology assessment. RFID must be subject to a formal technology assessment process, sponsored by a neutral entity, perhaps similar to the model established by the now defunct Congressional Office of Technology Assessment. The process must be multi-disciplinary, involving all stakeholders, including consumers.

Principles of Fair Information Practice. RFID technology and its implementation must be guided by strong principles of fair information practices (FIPs). The eight-part Privacy Guidelines of the Organisation for Economic Co-operation and Development (OECD) provides a useful model (www.oecd.org). We agree that the following minimum guidelines, based in part on these principles, must be adhered to while the larger assessment of RFID's societal implications takes place:

  • Openness, or transparency. RFID users must make public their policies and practices involving the use and maintenance of RFID systems, and there should be no secret databases. Individuals have a right to know when products or items in the retail environment contain RFID tags or readers. They also have the right to know the technical specifications of those devices. Labeling must be clearly displayed and easily understood. Any tag reading that occurs in the retail environment must be transparent to all parties. There should be no tag-reading in secret.

  • Purpose specification. RFID users must give notice of the purposes for which tags and readers are used.

  • Collection limitation. The collection of information should be limited to that which is necessary for the purpose at hand.

  • Accountability. RFID users are responsible for implementation of this technology and the associated data. RFID users should be legally responsible for complying with the principles. An accountability mechanism must be established. There must be entities in both industry and government to whom individuals can complain when these provisions have been violated.

  • Security Safeguards. There must be security and integrity in transmission, databases, and system access. These should be verified by outside, third-party, publicly disclosed assessment.

RFID Practices that Should be Flatly Prohibited:

  • Merchants must be prohibited from forcing or coercing customers into accepting live or dormant RFID tags in the products they buy.

  • There should be no prohibition on individuals to detect RFID tags and readers and disable tags on items in their possession.

  • RFID must not be used to track individuals absent informed and written consent of the data subject. Human tracking is inappropriate, either directly or indirectly, through clothing, consumer goods, or other items.

  • RFID should never be employed in a fashion to eliminate or reduce anonymity. For instance, RFID should not be incorporated into currency.

ACCEPTABLE USES OF RFID

We have identified several examples of "acceptable" uses of RFID in which consumer-citizens are not subjected to "live" RFID tags and their attendant risks.

  • Tracking of pharmaceuticals from the point of manufacture to the point of dispensing. RFID tags could help insure that these critical goods are not counterfeit, that they are handled properly, and that they are dispensed appropriately. RFID tags contained on or in the pharmaceutical containers should be physically removed or permanently disabled before being sold to consumers.

  • Tracking of manufactured goods from the point of manufacture to the location where they will be shelved for sale. RFID tags could help insure that products are not lost or stolen as they move through the supply chain. The tags could also assure the goods are handled appropriately. Tags should be confined to the outside of product packaging (not embedded in the packaging) and be permanently destroyed before consumers interact with them in the store.

  • Detection of items containing toxic substances when they are delivered to the landfill. For example, when a personal computer is brought to the landfill, a short-range RFID tag could communicate toxic content to a reader at the landfill. It is important to underscore that uses such as the landfill example do not require -- and should not entail -- item-level unique identifiers. The RFID tag would, rather, emit a generic recycling or waste disposal message.

CONCLUSIONS

We are requesting manufacturers and retailers to agree to a voluntary moratorium on the item-level RFID tagging of consumer items until a formal technology assessment process involving all stakeholders, including consumers, can take place. Further, the development of this technology must be guided by a strong set of Principles of Fair Information Practice, ensuring that meaningful consumer control is built into the implementation of RFID. Finally, some uses of RFID technology are inappropriate in a free society, and should be flatly prohibited. Society should not wait for a crisis involving RFID before exerting oversight.

Although not examined in this position paper, we must also grapple with the civil liberties implications of governmental adoption of RFID. The Department of Defense has issued an RFID mandate to its suppliers, schools and libraries in the have begun implementing RFID, the EU and the Japanese government have considered the use of RFID in currency, and British law enforcement has expressed an interest in using RFID as an investigative tool. As an open democratic society, we must adopt a strong policy framework based on Principles of Fair Information Practice to guide governmental implementation of RFID.

U.S. to require RFID chips in passports 

By Grant Gross, IDG News Service, 10/26/05

The U.S. government will require nearly all of the passports it issues to have a computer chip containing the passport holder's personal information by October 2006, according to regulations published this week.

Starting in early 2006, the U.S. Department of State will begin issuing passports with 64K byte RFID (radio frequency identification) chips containing the name, nationality, gender, date of birth, place of birth, and digitized photograph of the passport holder.

The chip would match the data on the paper portion of the passport and improve passport security by making it more difficult for criminals to tamper with passports, backers say. The U.S. government began looking at ways to make passports harder to forge in response to the terrorist attacks on the U.S. on Sept. 11, 2001.

After the State Department proposed RFID chips for passports in February, privacy groups such as American Civil Liberties Union (ACLU) and the Electronic Frontier Foundation (EFF) expressed concerns. Some RFID chips can be remotely scanned, allowing for criminals to covertly scan groups of passport holders at airports, the EFF said in April. The RFID passport could act as "terrorist beacons" because they could indiscriminately expose U.S. residents' personal information to strangers.

In a letter commenting on the State Department proposal, the EFF argued that the agency lacked congressional authority to require RFID chips in passports.

"RFID in passports is a terrible idea, period," said EFF Senior Attorney Lee Tien, in a posting to the EFF's Web site. "But on top of that, the State Department is acting without the appropriate authority and without conducting any form of credible cost-benefit analysis. It's asking Americans to sacrifice their safety and privacy 'up front' for a dangerous experiment that it hasn't even bothered to justify."

The State Department received 2,335 public comments on its February proposal to introduce electronic passports. More than 98 percent of the comments were negative, the State Department said, with most raising concerns about security and privacy.

In the passport rules released Tuesday, the State Department said it was taking several security precautions. The RFID chips will use encrypted digital signatures to prevent tampering, and they will employ so-called passive RFID chips that does not broadcast personal information unless within inches of an RFID reader machine. The e-passports will protect against data leaks by putting an "antiskimming" material to block radio waves on the passport's back and spine, the State Department notice said.

The new passports would comply with an International Civil Aviation Organization specification on e-passports, the State Department said.

Although the State Department changed its earlier proposal of a self-powered RFID chip to a passive one that relies on a reader machine's power, privacy concerns remain, said Barry Steinhardt, director of the ACLU's Technology and Liberty Program. Steinhardt called the State Department's security measures a "step forward," but he said bar codes could be used to match electronic data with paper data on passports.

"It still raises the question whether or not this is an appropriate technology," Steinhardt said. "There are still some essential concerns about whether this is secure or not."

But Neville Pattinson, director of technology and Government affairs for Texas RFID card vendor Axalto, praised the State Department's changes, including the passive chips and anti-skimming materials. "This is a fine example of the government listening to public opinion and adopting technology that protects citizen’s privacy,” he said. "With the changes, information cannot be extracted from it."

State Department officials were unavailable for comment on this story.

Wal-Mart, P&G Involved in Secret RFID Testing
American consumers used as guinea pigs for controversial technology

November 10, 2003

by Spychips

Wal-Mart and Procter & Gamble conducted a secret RFID trial involving Oklahoma consumers earlier this year, the Chicago Sun Times revealed on Sunday. Customers who purchased P&G's Lipfinity brand lipstick at the Broken Arrow Wal-Mart store between late March and mid-July unknowingly left the store with live RFID tracking devices embedded in the packaging. Wal-Mart had previously denied any consumer-level RFID testing in the United States. 

"It proves what we've been saying all along," says Katherine Albrecht, Founder and Director of Consumers Against Supermarket Privacy Invasion and Numbering (CASPIAN). "Wal-Mart, Procter & Gamble and others have experimented on shoppers with controversial spy chip technology and tried to cover it up. Consumers and members of the press should be upset to learn that they've been lied to." 

The Sun Times also reported that a live video camera trained on the shelf allowed Procter & Gamble employees, sometimes hundreds of miles away, to observe the Lipfinity display and consumers interacting with it. 

"This trial is a perfect illustration of how easy it is to set up a secret RFID infrastructure and use it to spy on people," says Albrecht. "The RFID industry has been paying lip service to privacy concerns, calling for notice, choice and control. But companies like P&G, Wal-Mart and Gillette have already violated all three tenets when they thought nobody was looking. This is exactly why we oppose item-level RFID tagging and have called for mandatory labeling legislation." 

The Lipfinity tests were conducted while Wal-Mart and Procter & Gamble were sponsors of the MIT Auto-ID Center, a consortium of over 100 corporations and government agencies founded in 1999. Auto-ID Center trials were overseen by a Board of Directors, which included both Wal-Mart and Procter & Gamble, along with the Uniform Code Council (UCC), the standards body that oversees the bar code. The UCC (along with EAN International) took over commercial functions from the Auto-ID center on November 1, 2003.

"Given the players, the Wal-Mart Lipfinity trial probably isn't an isolated incident," says CASPIAN spokeswoman Liz McIntyre. "UCC and Auto-ID Center documents suggest that other products, including Huggies baby wipes, Pantene shampoo, Caress soap, Purina Dog Chow and Right Guard deodorant were also slated for live RFID field trials. Coca Cola, Kraft, Kodak and Johnson & Johnson products are also implicated. However, it may be difficult for consumers to learn the extent of those trials in the current climate of secrecy and denials."  

(Links to documentation provided below.) 

Disclosure of the Broken Arrow trial is only the latest scandal to hit the privacy plagued RFID industry. Early this year, CASPIAN called for a worldwide boycott of Italian clothing manufacturer Benetton when the company announced plans to equip women's undergarments with live RFID tracking tags (see http://www.boycottbenetton.org). This summer, CASPIAN uncovered an RFID-enabled Gillette "smart shelf" in a Brockton, Massachusetts Wal-Mart and helped disclose Gillette's scheme to secretly photograph consumers picking up Mach3 razor blades in UK Tesco stores (see http://www.boycottgillette.com/spychips.html). The group also revealed confidential industry plans to "pacify" consumers and "neutralize opposition" in the hope that consumers will be "apathetic" and "resign themselves to the inevitability" of RFID product tagging (see press release).

CASPIAN encourages consumers to contact Wal-Mart, P&G and the UCC to voice their opinion about the use of RFID spy chips in consumer products. Contact information for these companies is provided on the group's RFID website at Spychips home page.
