Description
Technical field
The present invention relates to a kind of subway booking, ticket checking method, be specifically related to a kind of subway booking, ticket checking method based on Quick Response Code identification.
Background technology
In recent years, subway because its freight volume is large, comfortableness is high, pollute less, low power consumption and other advantages, be more and more subject to each side and paid attention to, become a kind of fast, safety, urban public transport instrument efficiently.At present, the subway passenger traffic department in domestic each city has all set up comparatively perfect booking, ticket-checking system, subway adopts the carrier of non-contact IC card as ticket card at present, but non-contact IC card cost is too high, easily occurs the situation of ticket medium cost higher than ticket itself.
Quick Response Code is applied in the booking of subway, can address the above problem, utilize smart mobile phone scanning Quick Response Code to become the direction of development of new techniques.Quick Response Code is the chequered with black and white graphic recording data symbol information distributing in plane (two-dimensional directional) according to certain rules with certain specific geometric figure.Quick Response Code is the one of DOI (Digital Object Unique Identifier, digital object unique identifier).
On coding, utilize dexterously " 0 ", the concept of " 1 " bit stream that form computer-internal logical foundations, represent word numerical information with several geometrical bodies corresponding with scale-of-two, automatically process to realize information by image input device or photoelectric scanning device automatically identifying and reading.In the two-dimensional bar code of numerous species, conventional code system has: Data Matrix, MaxiCode, Aztec, QR Code, Vericode, PDF417, Ultracode, Code 49, Code16K etc.
Every kind of code system has its specific character set; Each character occupies certain width; There is certain verifying function etc.Also there is the feature such as information automatic identification function and processing graphics rotation variation to different rows simultaneously.
Quick Response Code is a kind of barcode standard more senior than one dimension code.One dimension code can only be gone up expressing information in a direction (being generally horizontal direction), and Quick Response Code can be stored information in horizontal and vertical direction.One dimension code can only be made up of numeral and letter, and Quick Response Code can be stored the information such as Chinese character, numeral and picture, and therefore the application of Quick Response Code wants much wide.
Existing Quick Response Code ticket card, as high guaranteed votes, adopts 2 D code information is printed on paper ticket, data are fixed, ticket card is easily replicated imitation, conventionally needs to adopt the mode of networking to inquire about the use that prevents multiple ticket making card whether out of the station of this ticket, once there is suspension situation, cannot arm's length transaction.In addition, in the time of the commuter rush hour, inquire about too intensive, larger to the pressure of network and server.
Utilize dynamic two-dimensional code display, asymmetrical cryptographic method dynamic data to be carried out to the method for digital signature, can effectively prevent copying and forging.Asymmetrical encryption algorithm is a kind ofly to use a pair of complete difference but the PKI (public key) of coupling and private key (private key) carry out the algorithm of data encryption, decrypting process mutually.Different from symmetric encipherment algorithm, asymmetrical encryption algorithm needs two keys: PKI and private key.PKI is mutually to mate with private key, if data are encrypted with PKI, only have and could decipher with corresponding private key.
The ultimate principle of asymmetrical encryption algorithm is: if originator is wanted to send the enciphered message of only having destination to understand, first originator must know destination's PKI, then utilizes destination's PKI to encrypt original text; Destination receives and encrypts after ciphertext, uses the private key ability decrypting ciphertext of oneself.Obviously, adopt asymmetrical encryption algorithm, transmitting-receiving letter both sides are before communication, and the PKI that destination must generate oneself already is at random given originator, and oneself retains private key.
The general process that asymmetrical encryption algorithm is realized exchanges data is: Party A generates pair of secret keys and a handle is wherein disclosed as PKI to other side; The Party B who obtains this PKI sends to Party A after using this key to be encrypted the data of needs transmission again; The private key that Party A preserves with oneself is again decrypted the data after encrypting.Party A can only decipher by any information after its public key encryption with its private key.
Because asymmetric algorithm has two keys, algorithm secrecy is better, and has eliminated final user and exchange the needs of key, thereby is specially adapted to the data encryption in distributed system.The DSA that the asymmetrical encryption algorithm of widespread use has RSA Algorithm and NBS to propose.
Simultaneously, asymmetric cryptosystem technology is also encryption technology main in e-commerce system, is generally used for the distribution (digital envelope) of symmetric cryptographic key, the realization of digital signature (carrying out authentication and information integrity inspection) and transaction anti-repudiation etc.
Digital signature is some data that are attached in data cell, and common method is that transmit leg uses the private key of self to be encrypted to the hashed value of data or data, and sends to take over party after being attached to original data using the result of encryption as signed data; Take over party uses the PKI of transmit leg signed data is decoded and compare with the hashed value of raw data or data, if unanimously think, signed data is legal.
In real trade process, the PKI that CA center is user is signed and issued public key certificate, to realize the distribution of PKI and to prove its legitimacy.Public key certificate, conventionally referred to as certificate, is the file that comprises PKI and PKI owner information of a Ge Jing CA center digital signature.CA center You ChengCA mechanism, be certificate granting center (Certificate Authority), or title certification authority agent, as the third party who is trusted in e-commerce transaction, bear the responsibility of the legitimacy inspection of PKI in PKI system, being responsible for specially and providing and manage the required digital certificate of all entities of participating in business, and key is effectively managed, is the core of safe electronic message exchange.
The problems such as at present subway ticket selling and checking system time that also has that booking efficiency is low, phase commuter rush hour lines up for tickets is long, ticket single use cost is large.
Summary of the invention
Goal of the invention: in order to solve subway booking in prior art, ticket checking queuing time is long, the problem that equipment cost is high, the invention provides a kind of subway booking, ticket checking method based on Quick Response Code identification, mainly carry out booking by smart mobile phone and Quick Response Code, check Quick Response Code can complete booking and ticket checking by ticket-checking system, solved the deficiencies in the prior art.
