ZDNet.com reports that computer-security software maker RSA Security has developed a new technology for protecting information emitted by radio frequency identification tags.

The RFID cloaking system is intended to guard proprietary data located on chips used to carry product information. The RSA Blocker Tag technology uses a jamming system designed to confuse RFID readers and prevent those devices from tracking data on individuals or goods outside certain boundaries.

The blocker tags work by emitting radio frequencies designed to trick RFID readers into believing that they are being presented with unwanted data, or spam, causing the information collection devices to shun the incoming transmission. RSA claims that by placing an RFID-loaded product into a parcel bearing one of the blocker tags, the system would cause RFID readers to miss any information carried by the product in the bag, thereby protecting consumers.

The company also promised that its cloaking system would not interfere with the normal operation of RFID systems or allow hackers to use security technology to bypass theft control systems or launch denial-of-service attacks.
