Information compression for remote readable ID tags

Application of Smart Materials to Wireless Id Tags and Remote Sensors

Material structures having an electromagnetic or magnetomechanical resonance can be excited or detected remotely using an antenna. Incorporating smart materials into such structures provides new opportunities to encode ID and sensor information in the electromagnetic signature of the “tag.” In this way, it is possible to create tags which not only have a unique ID but which can also respond to ...

Remote Power Analysis of RFID Tags

We describe the rst power analysis attack on passive RFID tags. Compared to standard power analysis attacks, this attack is unique in that it requires no physical contact with the device under attack. The power analysis can be carried out even if both the tag and the attacker are passive and transmit no data, making the attack very hard to detect. As a proof of concept, we use power analysis to...

"Power tags" in information retrieval

Purpose – Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document-specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems. Design/methodology/approach – In a theor...
