Computer World Network News US special personnel safety business RSA SECURITY researchers have taught a technology to prevent information transmission, which is called blocking tags, whose size and cost are RFID (wireless frequency) Identification) The mark is similar, but it will destroy the information transmitted to the scanning device and prevent people from collecting data.
According to RSA's backbone scientist ARI Juels, this technology is just one of RFID barrier technology. At present, researchers are still studying and improving it, and is just a concept in laboratory experiments. However, these researchers will develop prototype chips to see if the chip manufacturer is interested in manufacturing this chip. The size of Blocker and RFID is equivalent to sand, and the cost is about 10 cents.
RFID technology is to transfer product serial numbers wirelessly to the scanner using microchips without being manually transmitted. This technology is to increase the management of the supply chain and the prevention of the store's products. However, consumer privacy groups are worried, and if this product tracking mark technology is introduced from the store to the family, this may undermine people's privacy. Many retailers regard RFID as an inevitable replacement of a barcode tracking system. Because it can reduce the cost of manufacturing, it can also improve the profit of the retail industry.
RSA's technology needs to write all information for the object used, and if important functions of the object, it is also necessary to write. Use the Blocker tag, users and businesses can use the RFID tag without sacrificing their privacy.
