What are the applications of RFID in Information Security?

RFID stands for radio frequency identification. It is a technology that incorporates the need of electromagnetic or electrostatic coupling in the radio frequency (RF) area of the electromagnetic spectrum to uniquely recognize an object, animal or person. RFID is appearing into increasing use in market as an alternative to the bar code.

The benefit of RFID is that it does not needed direct contact or line-of-sight scanning. An RFID system includes three components such as an antenna and transceiver and a transponde. The antenna needs radio frequency waves to send a signal that activates the transponder.

The notion of security and safety defines Digital and printed Information Security, and brand and packaged product security against unauthorized access or alteration, partial or complete deletion, damaging or destruction. It also define the complete protection of the confidentiality availability and integrity of the data or product.

  • Data security and protection system − It is based on the method and the degree of detectability, security solutions have the following groups −

    • Overt Security Solutions
    • Covert Security Solutions
    • Characters and symbols which can be regenerated by machine tools, characters, line, colour or multiple code sequences, which can be made visible by utilizing radiation (lasers, ultraviolet, infrared, radio, x-ray and electron beam) or chemical reagents.
  • RFID solutions for document management − Document recognition with RFID stickers are

    RFID can be used on the files in the form of an identification sticker.

    The collision-free technology enables the identification of thousands of documents per second; thus it is conceptual for archive application.

    The management of high safety level reports − the sticker can data who, when and how long had access to the files.

    E-Inks, including materials containing liquid-dispersed, positively charged white particles and negatively charged black microcapsules, which become white or black based on the polarity of the magnetic or electric area, and their planar distribution carries two-dimensional visual data.

    Liquid RFID Ink Solutions were produced by Cross ID Communication Materials, and they are able to recognize the materials or products to which they are inserted, by emitting radio signals. By inserting this liquid to printer and photocopier ink, a tamper-proof, high security printing product can be created.

    The Smart Paper, the media type of the future, which can be programmed by utilizing the semiconductor polymers, microchips, radio frequency devices, or printed integrated electronic components located on the surface of the paper.

    The Digital watermark first appeared in the industry of printed and photocopied products in 1992. It can include a number and code combination which can be reconstructed by a machine only and a digital signature. The visible or invisible watermark can be located on the surface of the media, or embedded into the material of the media, based on the purpose of protection.
