Description
Technical field
The present invention relates to a kind of subway booking, ticket checking method, and in particular to a kind of subway booking recognized based on Quick Response Code,
Ticket checking method.
Background technology
In recent years, subway because its freight volume is big, comfortableness is high, pollute less, low power consumption and other advantages, increasingly by each side
Pay attention to, as quick, the safe and efficient urban public transport instrument of one kind.At present, the subway passenger traffic department in each domestic city
More perfect booking, ticket-checking system are all established, current subway is but non-using carrier of the non-contact IC card as ticket card
Contact Type Ic Card cost is too high, ticket medium cost easily occurs higher than the situation of ticket in itself.
It in the booking that Quick Response Code is applied to subway, can solve the above problems, Quick Response Code has been scanned using smart mobile phone
Through the direction for becoming development of new techniques.Quick Response Code is according to certain rules in plane (two-dimensional square with certain specific geometric figure
To) the chequered with black and white graphic recording data symbol information of distribution.Quick Response Code is DOI (Digital Object Unique
Identifier, digital object unique identifier) one kind.
Dexterously made on coding using the concept of " 0 ", " 1 " bit stream for constituting computer-internal logical foundations
The geometrical body corresponding with binary system with several represents word numerical information, passes through image input device or optoelectronic scanning
Equipment automatically identifying and reading is to realize that information is automatically processed.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；With certain verifying function etc..
The features such as also there is the information automatic identification function and rotationally-varying processing figure to not going together simultaneously.
Quick Response Code is a kind of barcode standard than one-dimension code higher level.One-dimension code can only (be usually level in a direction
Direction) on expressing information, and Quick Response Code is both horizontally and vertically can storage information.One-dimension code can only be by numeral and letter
Composition, and Quick Response Code can store the information such as Chinese character, numeral and picture, therefore the application field of Quick Response Code is much broader.
Existing Quick Response Code ticket card, such as high guaranteed votes, be printed upon using by 2 D code information in paper ticket, data be it is fixed,
Ticket card is easily replicated imitation, it usually needs inquire about whether the ticket is out of the station to prevent that replicating ticket card makes by the way of networking
With can not arm's length dealing if there is offline condition.In addition, in the commuter rush hour, inquiring about excessively intensive, to network and service
The pressure of device is larger.
The method being digitally signed using Dynamic Announce Quick Response Code, asymmetrical cryptographic method to dynamic data, Ke Yiyou
Effect prevents copying and forging.Asymmetrical encryption algorithm is a kind of using a pair of entirely different public key (public being but mutually matched
Key) and private key (private key) carry out data encryption, the algorithm of decrypting process.It is different from symmetric encipherment algorithm, it is asymmetric
AES needs two keys：Public key and private key.Public key is mutually matched with private key, if being added with public key to data
It is close, it could only be decrypted with corresponding private key.
The general principle of asymmetrical encryption algorithm is：If originator wants to send the encryption letter for only having destination to understand
Breath, originator must know the public key of destination first, then encrypt original text using the public key of destination；Destination, which receives, to be added
After ciphertext, ciphertext could be decrypted using the private key of oneself.Obviously, using asymmetrical encryption algorithm, transmitting-receiving letter both sides are in communication
Before, destination must give the public key that oneself is generated at random already originator, and oneself retains private key.
Asymmetrical encryption algorithm realizes that the general process of data exchange is：Party A generates a pair of secret keys and by one therein
Disclosed as public key to other sides；Obtain sending out again after the Party B of the public key is encrypted the data for needing to transmit using the key
Give Party A；Data after the private key pair encryption that Party A is preserved with oneself again are decrypted.Party A can only with its private key decryption by
Any information after its public key encryption.
Because asymmetric algorithm possesses two keys, algorithm secrecy preferably, and eliminates end user's exchange key
The need for, thus it is particularly suitable for use in the data encryption in distributed system.Wide variety of asymmetrical encryption algorithm has RSA Algorithm
The DSA proposed with NBS.
Meanwhile, asymmetric cryptosystem technology is also main encryption technology in e-commerce system, is generally used for symmetric cryptography
The distribution (digital envelope) of key, the realization (integrity check for carrying out authentication and information) of digital signature and transaction are prevented supporting
Rely etc..
Digital signature is attached to some data in data cell, and common method is sender to data or data
Hashed value is encrypted using the private key of itself, and is sent to after the result of encryption is attached into original data as signed data
Recipient；Recipient is decoded to signed data using the public key of sender and carried out with the hashed value of initial data or data
Compare, think that signed data is legal if consistent.
During real trade, public key certificate is signed and issued in CA centers for the public key of user, to realize distribution and the card of public key
Its bright legitimacy.Public key certificate, often referred to simply as certificate, are one and are gathered around through what CA center numbers were signed comprising public key and public key
The file of the person's of having information.CA centers are also known as CA mechanisms, i.e. certificate authority (Certificate Authority), or card
Book authorized organization, as the third party of trust in e-commerce transaction, undertakes the legitimacy inspection of public key in Public Key Infrastructure
Responsibility, is responsible for specially providing and manages the digital certificate needed for all entities participated in business, and key is effectively managed,
It is the core that safe electronic information is exchanged.
