As shown in figure 4, the information required for product after server end first passes around network layer encryption, is divided in Information Level
Encrypted information is obtained after layer encryption, after interleaver, obtains information to be compiled, by these information, carries out two dimensional code
Coding, obtains two dimensional code, is placed on product.
In network layer information secure context, cipher mode is divided into symmetric cryptography and asymmetric encryption.Symmetric cryptography needs
Same key is used when encryption and decryption.It is so-called symmetrical such as Fig. 7, it is exactly the same key of businessman and server usage mode
It is encrypted and decrypted.Key is control encryption and the instruction of decrypting process.Algorithm is one group of rule, it is specified that how to be encrypted
And decryption.The advantages of symmetric encipherment algorithm is that algorithm discloses, calculation amount is small, enciphering rate is fast, encryption efficiency is high.Its speed is fast,
But key management is more too fat to move, lacks flexibility.
In asymmetric encryption, encryption code key is different with decryption code key, and encryption code key is known as public key, and decrypts code key and be known as
Private key.As shown in fig. 6, give public key publication to other people after the present invention generates a pair of of public key and private key by algorithm, businessman can be with
By message using being issued after public key encryption to server, after server receives message, using the private key of server by message solution

After network layer encryption, data are carried out to the multi-level encryption of Information Level, obtain input data.Wherein Information Level adds at many levels
Close, each key is key 1, key 2 ..., key N, for the obtained data after encrypting s, and if only if acquisition
Key key s, key s+1 ..., the data after obtaining encryption s can be successively decrypted after key N.
Channel coding is by introducing redundant digit in the data transmitted, to avoid digital signal from going out in transmit process
Existing error code.Channel coding for detecting mistake is referred to as error detection coding, and both can error detection can the channel coding of error correction claimed
Make Error Correction of Coding.The introducing of redundant digit improves the reliability of channel communication, but redundant digit introduces will will increase signal again
Transmission rate will also reduce bandwidth.
Many codings, such as Hamming code, convolutional code etc., contribute to memoryless channel, are for independent error
Design.But in some cases, mistake is mainly to happen suddenly, and a burst error will cause a succession of mistake.And interlaced code
Burst error that is very long and being not limited only to one can be corrected.
The purpose of interweaving encoding is a longer burst error to be separated into random error, then with correcting random error
(FEC) technology of coding eliminates random error.Interleave depth is bigger, then dispersion is bigger, and anti-burst error ability is also stronger.But
Interleave depth is bigger, and the interweaving encoding processing time is longer, so that data transmission delay be caused to increase, that is to say, that interweaving encoding
It is using the time as cost.Therefore, interweaving encoding belongs to time implied diversity.Decline under practical mobile communication environment will make
At the bursty errors of digital data transmission.Can be discrete using interweaving encoding technology and this bursty errors be corrected, improves and move
The transmission characteristic of dynamic communication.
And after user obtains product, user is scanned the two-dimensional code by scanning device, extracts information to be compiled, is passed through
Obtain encrypted information after crossing the decompiling of interleaver, this is passed through together with existing key communication layers upload onto the server into
Row compares, and feeds back to the information that user accordingly decrypts layer.
