The present invention discloses a reading device and a system of encrypted bar codes. The device comprises essentially an imaging system, a decoding system and an output system. An additional read-write system of smart cards is connected with the mainboard of the reading device of bar codes and is used for transmitting the processed information to the output system. The read-write system of smart cards is arranged with smart cards written with keys. The present invention provides the method that a decrypting step is added besides a reading step, a decoding step and an output step. The keys contained in the digital information transmitted by the decoding system are contrasted with the keys of the smart cards of a read-write system of smart cards, decrypted and transmitted to the output system by the read-write system of smart cards. The present invention adopts the read-write system of smart cards and results in a fact that the information of the bar codes read by a reading device of the bar codes cannot be displayed until being decrypted by smart cards. The device aims at the application of a bar code reading that needs security and encryption.

Summary of the invention
The purpose of this invention is to provide a kind of bar code reader that can distinguish enciphered bar code.
Another object of the present invention provides a kind of bar code reading method that can distinguish enciphered bar code.
For achieving the above object, the reading device of enciphered bar code of the present invention mainly comprises imaging system, decode system and output system, other has a smart card read-write system to be connected with the mainboard of bar code reader, receive the numerical information of decode system output, and the information transmission after will handling gives output system, and this smart card read-write system is equipped with the smart card with key.
The present invention utilizes common bar code reader, smart card read-write device of design and installation, and the bar code information that bar code reader is distinguished must could show through after the smart card deciphering.This equipment is primarily aimed at the bar code reading that needs safety encipher and uses.
The present invention is on information transmission, and the mainboard of smart card read-write system and bar code reader is finished the mutual of information by the physical connection transmission signals.
The present invention can encrypt as " symmetric cryptography " and " asymmetric encryption " two kinds and use: promptly the secrete key of smart card of smart card read-write system and quilt are distinguished bar code key identical (PKI mode), and this is that symmetric cryptography is used; Also can adopt the secrete key of smart card and quilt recognition bar code key different (PKI and private keys) of smart card read-write system, this is the asymmetric encryption mode.
For realizing another object of the present invention, the reading method of enciphered bar code of the present invention comprises:
The recognition step by the imaging system of bar code reader, is obtained the bar code graphics that has the ciphertext key, and is finished digitizing, is transferred to decode system;
Decoding step, the decode system of bar code reader is decoded to the numerical information that receives, and obtains including the numerical information of ciphertext key;
The output step, the information after the recognition that the output system of bar code reader will receive outputs to output port;
Other has a decryption step, the key that numerical information contained that the smart card read-write system of bar code reader comes the decode system transmission, compare with the secrete key of smart card of smart card read-write system, under the situation that meets the deciphering requirement, the smart card read-write system is opened ciphertext, be reduced into bar code raw information, and be transferred to output system.
Like this, the bar code that contains the ciphertext key must could obtain original bar code information by decryption step, can maintain secrecy to bar code information effectively.
