First Claim
1. A privacy protection method for preventing an invasion of privacy performed by reading an proper identifier and on the basis of said proper identifier, including:
- an identifier guard step of bringing an proper identifier of a radio identifier transmitter affixed to an article purchased and thereby possessed by a personal user into an identifier guard state not readable by a stranger according to the intention of said personal user;
an identifier generation step of generating an identifier for disturbing a privacy invader with a privacy protection identifier transmitter possessed by said personal user;
a transmission step of transmitting said identifier generated through said identifier generation step from said privacy protection identifier transmitter when receiving an identifier transmission request; and
a reading step of rendering the identifier of said radio identifier transmitter in the identifier guard state readable according to the intension of the personal user, whereinsaid identifier generation step includes a variable identifier generation step capable of generating an identifier different from a precedently transmitted identifier; and
said transmission step transmits the same identifier as a precedently transmitted identifier when receiving an identifier transmission request again within a prescribed time from precedent identifier transmission.

Abstract
To prevent privacy invasion performed according to a proper identifier which has been read.
A pseudo-RFID transmission device for transmitting a pseudo identifier (RFID) for disturbing an invader is provided to an individual user. When an RFID transmission instruction is received from a tag reader (SAI), a variable type pseudo RFID different from the one which has been transmitted previously is transmitted (SA3 to SA5) and different RFID is transmitted each time for the same person. The respective pseudo RFID transmission devices are grouped into a plurality of types, so that the pseudo RFID transmission devices belonging to the same group transmit their variable type pseudo RFID while increasing the possibility to transmit common pseudo RFID accorded with one another. An area is specified for each group and the respective pseudo RFID transmission devices are provided to individual users, so that the same RFID may be transmitted for the same person.

2. A privacy protection method for preventing an invasion of privacy performed by reading an proper identifier of a radio identifier transmitter affixed to an article purchased and thereby possessed by a personal user and on the basis of said proper identifier, including:
-
an identifier generation step of generating an identifier for disturbing a privacy invader with a privacy protection identifier transmitter possessed by said personal user; and a transmission step of transmitting said identifier generated through said identifier generation step from said privacy protection identifier transmitter when receiving an identifier transmission request, wherein said identifier generation step includes an adjusted identifier generation step for generating an adjusted identifier so adjusted that an identifier transmitted from said personal user possessing said privacy protection identifier transmitter is identical to an identifier transmitted from a stranger in response to the identifier transmission request, for causing such a different person identical identifier transmission phenomenon that identical identifiers are transmitted even in case of transmission from different persons.
