Fragile Watermarking for Tamper Detection in RFID Tag using Arnold Transform

Tampering is one of the threats to RFID system in which adversaries alters the tag data to draw unethical benefit or to disrupt the normal functioning of the RFID enabled organization. Various methods of fragile watermarking based tamper detection exist to address the tag data tampering problem. We propose an enhanced method of tamper detection where secret key hiding is more secured due to use of Arnold Transform. Moreover, proposed method can detect tampering in SN field also, in addition to EM and OC field of the tag, which helps to avoid any pandemonium in the database.
