The utility model discloses a server 2 collects authentication server and terminal server as an organic whole, both can carry out the watermark to the stereoplasm memory and encrypt, also can carry out safety certification to the encryption stereoplasm memory that receives.

The server 2 is connected with auxiliary devices such as a keyboard, a camera, a printer and the like.

The first embodiment is as follows: as shown in fig. 2 and 3, when the hardware memory is a usb disk 6, the hardware memory is labeled as an RFID electronic tag 5, and the identifier is an RFID reader/writer 4; the RFID reader-writer 4 is an existing RFID reader-writer, and the RFID reader-writer is arranged at the upper part of the server 2 or at the upper end of the outer side of the shell 3. The existing RFID read-write integrated machine can read the content on the RFID electronic tag 5 remotely.

The RFID electronic tag 5 is adhered to the upper part of the U disk 6 or embedded in the shell of the U disk 6.

The RFID read-write integrated machine is connected with the server 2 through a USB data line.

The USB flash disk 6 with the RFID electronic tag 5 is directly placed on the RFID read-write integrated machine, and then the information of the server 2 can be written into the RFID electronic tag 5.

Radio Frequency identification (rfid) technology, also called radio Frequency identification (rfid), is a communication technology commonly called electronic tag. The specific target can be identified and the related data can be read and written by radio signals without establishing mechanical or optical contact between the identification system and the specific target.

RFID readers are also divided into mobile type and fixed type, and the RFID technology is widely applied in the prior art, such as libraries, access control systems, food safety traceability, bus cards and the like.

The most basic RFID electronic label system consists of three parts:

label (Tag): each tag has a unique electronic code, and the high-capacity electronic tag has a storage space which can be written by a user and is attached to an object to mark a target object;

reader (Reader): the device for reading (sometimes writing) the label information can be designed to be handheld or fixed;

antenna (Antenna): radio frequency signals are communicated between the tag and the reader.

Under the condition that the RFID electronic tag is covered, the RFID electronic tag can penetrate through paper, wood and non-metal or non-transparent materials of a plastic stool to perform penetrating communication.
