Abstract
We propose a method to protect the tag's information from illegal reader in RFID system. In this method, a special tag called ownership tag makes intentionally collisions during singulation. By the forced collision of an ownership tag a reader can obtain the information of ordinary tags. Whereas a reader can not find my information on tag's ID without the ownership tag.
