Definitions

  • RFID Radio Frequency Identification
  • active RFID tags which are battery powered devices that transmit a signal to a reader, and are typically readable over distances greater than one hundred feet
  • passive RFID tags which are not battery powered but draw energy from electromagnetic waves from an RFK) reader, and typically are readable over a distance of less than ten feet
  • semi-passive RFID tags which employ a battery to run the circuitry of a chip but rely on electromagnetic waves from a reader to power the transmitted signal.
  • an RFID tag typically includes an RFID tag chip
  • the RFBD tag chip will include non- volatile memory that stores a unique identification number (UID).
  • the RFED tag chip also includes non-volatile re-writable memory that may be utilized to store information.
  • RFID tags have many physical formats, such as a microchip from 30 to 100 microns thick and from 0.1 to 1 mm across, joined to a minute metal antenna, or they can be in the form of deposited alloys 0.5 to 5 microns thick on a 20 micron polyester ribbon 1 mm across as used in some banknote security ribbons.
  • Another form is the 'Coil-on-Chip' system, which is a 2.5 mm square integrated circuit with a coil mounted directly on the chip.
  • the chip is a read-write chip with 108 bytes of re- writable memory.
  • RFID tags are interrogated and read using an RFID reader.
  • the RFID reader supplies power to the RFID tag while reading the RFE) tag.
  • FIG. 1 shows one exemplary prior art system 100 for reading RFID tag data.
  • System 100 is shown with an RFID reader 102, an RFID tag 108 and an application 104.
  • Application 104 interacts with RFE) reader 102, via connection 106, to read from, and write to, RFE) tag 108.
  • RFE) tag 108 has a finite memory capacity, which may not be increased without redesign or RFE) tag 108.
  • FIG. 2 shows an exemplary memory map 200 of prior art RFE ) tag 108, FIG. 1.
  • Memory map 200 is shown with a UE) section 202, an application family identifier (AFI) section 204, a data storage format identifier (DSFE)) section 206, security section 208 and a plurality of sections containing user blocks 210.

  • DSFE) 206 contains a plurality of bits that specifies the memory format (e.g., number of sections, type of memory, etc) of RFE) tag 108.
  • Security section 208 has a plurality of bits, each relating to a section of memory map 200, indicating which sections, if any, are write-protected. For example, a first bits within security section 208 may indicates if user block 210(1) is write-protected, a second bit of security section 208 may indicate if user block 210(2) is write protected, and so on.
  • Each section of memory map 200 may be read by RFE) reader 102, and each section of memory map 200 that is not write protected may be written to by RFE) reader 102.
  • RFE tags are available with many different memory sizes, they are typically limited to 2048 bits. It has not been previously possible to increase memory capacity of RFE) tag 108 without developing and manufacturing a special RFE) tag with a specific amount of additional memory and deploying it to the location of use. Therefore, the cost of increasing the memory capacity of RFE) tag 108 is significant. A solution for increasing the size of usable memory corresponding to a particular RFE) tag without developing and deploying a new RFE ) tag is therefore desired.

  • Memory in the plurality of RFID tags may be organized to provide error recovery and redundancy such that if any one (or more, depending upon the redundancy scheme) RFID tag fails, the data on that tag can be recovered.
  • the RFID mega-tag may be employed to provide increased data security relative to single RFID tags.
  • part of the memory in each of a plurality of RFID tags 304(1), 304(2), 304(3) and 304(4) of RFID mega-tag 308, FIG. 3, is utilized to provide redundancy and error correction for RFID mega-tag 308.
  • Combiner 302 then performs error correction and recovery of data read from RFID mega-tag 308.
  • RFID mega-tag 308 may appear to application 406, FIG. 4, as a conventional RFID tag with high reliability. Writing of error correction information and redundant data is also handled by combiner 302.
  • keying data may be distributed across a plurality of RFID tags of an RF]D mega-tag, thereby requiring that each RFID tag be present (and readable) for the key to be operable.
  • a variant of this method stores identity data on each tag (e.g. time of day) during encryption and then utilizes this identity data when decrypting as part of an Identity Based Encryption system (IBE).

Abstract

Cette invention concerne un système et un procédé permettant de générer une étiquette RFID à mémoire étendue par lecture de données à partir d'une mémoire qui contient une pluralité d'étiquettes RFID sur chacune desquelles des informations d'identification d'étiquette sont stockées. Il convient de combiner les données, conformément aux informations d'identification d'étiquette stockées sur au moins une des étiquettes RFID, pour générer l'étiquette RFID à mémoire étendue. Les marques de séquencement peuvent être stockées en mémoire dans chacune des étiquettes RFID pour permettre aux données d'être combinées conformément aux marques de séquencement.
