1.3 Security and privacy aspects

1. Unique Identifier (UID)

The UID can not be altered and guarantees the uniqueness of each label.

2. OTP Memory for EPC Code

The memory for the EPC Code is an one time programmable memory, which ensures

that the data can not be changed after user programming.

3. Password protected memory management (Read/Write access)

Pages (1 page = 4 blocks of 4 byte each) can be protected with a password, which

ensures that only authorized users get read/write access to the protected parts of the

user memory (anti counterfeiting).

4. Password protected Label Destroy

With the 32-bit destroy password an addressed label can be destroyed with the

Destroy command. That status is irreversible and the label will never respond to any

command again.

5. Password protected Privacy Mode

With the 32-bit Privacy password a label can be set to the Privacy mode with the Set

to Privacy Mode command. In that mode the label will not respond to any command

except of the command Get Random Number till it receives again the right Privacy

password. That mode is especially designed to meet the increasing demand to take

care of the customers privacy.

6. Password protected EAS Functionality

With the 32-bit EAS password the addressed label can be set in a mode that the

commands Set EAS and Reset EAS are only executed by the label if the right EAS

password is transmitted to the label within the mentioned commands.
