Intelligent district cloud system base on mobile phone dynamic safety two dimension code recognition

The invention provides an intelligent district cloud system base on mobile phone dynamic safety two dimension code recognition. The intelligent district cloud system comprises an intelligent mobile phone equipped with a two dimension code application module, a two dimension code cloud management platform and a door control systemapparatus with a two dimension code recognition module, and the door control system apparatus and the intelligent mobile phone are respectively connected to the two dimension code cloud management platform by network connection. The intelligent mobile phone generates anencrypted two dimension code image key with positional information for opening the door control system apparatus by the two dimension code application module, and sends the two dimension code image key to the two dimension code cloud management platform for thedoor control system apparatus to scanthe two dimension code image key for comparison and discrimination.The two dimension code management platform is used for recording and setting the door control system permissions of users, and setting permissions of two dimension code image keys generated from users and carrying out storage and backup of usage condition data of two dimension code image keys generated from users. The gate inhibition apparatus is used for reading the two dimension code image keys obtained by users, sending the keys to the two dimension code cloud management platform for proofread. When someone proofreads something such as a book or an article, they read it before it is published in order to find and mark mistakes that need to be corrected. and discrimination, and executing corresponding access control actions according to the comparisonresults.
