Description
Technical field
The invention belongs to planar bar code technology and encryption technology fields, and more precisely, it is shared single that the present invention relates to one kind
The two-dimension code anti-counterfeit authentication method of vehicle and method of hiring a car.
Background technique
The new things that bicycle is generated as Internet of Things cloud+epoch are shared, are city, life style locating for a kind of and people
And the novel trip mode that life attitudes are all closely bound up, it greatly facilitates the trip of citizen.However, with major shared
The addition of bicycle operator, the quantity for sharing bicycle are presented blowout and increase, and there is swindling gang on the market in original two dimensional
Trojan horse is planted on code and steals the personal information and property of user.The peaces such as userspersonal information's leakage and property are stolen
Full problem repeated, and be shared bicycle company urgent problem.
Two dimensional code is the chequered with black and white square being distributed on planar direction according to certain rules with specific geometric figure
The barcode technology of new generation of shape square matrix record data symbol information, which has, to contain much information, and error correcting capability is strong, and recognition speed is fast, secrecy
Property high, the characteristics such as traceability is high, and damage resistance is strong, and redundant is big, and cost is cheap.Mobile phone two-dimension code is planar bar code technology on mobile phone
Application, have been widely used for invitation card at present, poster is registered, business card, direction board, the various occasions such as exploitation.If using
Two dimensional code is needed when certain important events transmitting has the more demanding data of identity information, timeliness to its enciphering and deciphering algorithm
It optimizes.
The maximum feature of public key algorithm is will to encrypt to separate with decryption capabilities using two association keys, one of them
Key is disclosed, referred to as public-key cryptography, referred to as open key；Another key be for user it is dedicated, thus be secrecy, claim
For privacy key, abbreviation secret keys, for decrypting.Therefore public-key cryptosystem is also referred to as conbined public or double key cipher system.Algorithm system has
Following key property: it is computationally infeasible to solve secret keys for known cryptographic algorithm and encryption key.It is widely used in each
Kind information is encrypted, and is also widely used in authentication, such as RSA technology.If using two dimensional code certain
When important events transmitting has the data of identity information, then its ciphering process should be optimized in conjunction with the above encryption technology.
Summary of the invention
It is an object of the present invention to pour in society for bicycle is nowadays shared, there is swindling gang on the market and exist
The shared bicycle safety problem such as plantation trojan horse and personal information and the property of stealing user, proposes one on original two dimensional code
The shared bicycle two-dimension code anti-counterfeit authentication method of kind and method of hiring a car.
What the present invention adopts the following technical solutions to realize:
A kind of shared bicycle two-dimension code anti-counterfeit authentication method, including encryption, anti-fake two-dimension code generate, two-dimentional code authentication, solution
It is close, in which:
(1) encrypt: for share vehicle security code that bicycle company provides as encryption key, to original two dimensional code into
Row encryption；
(2) anti-fake two-dimension code generates: for being handled two-dimensional barcode information, being generated the anti-fake two-dimension code of encryption；
(3) two-dimentional code authentication: to prevent the toxic two dimensional code downloading malice APP of scanning input from hiring a car, there is information and wealth
Produce the problem of losing；
(4) it decrypts: being decrypted with to the two dimensional code of encryption to obtain two-dimensional barcode information.
Further, the vehicle security code that the shared bicycle company provides includes vehicle identification code and random code, the vehicle
Identification code includes: vehicle material information, vehicle type information, vehicle place of production information, processor's information, product batches letter
Breath and identification code generate temporal information.
