Nowadays,whether it is a bus card,or a dining hall,or a communication connection,our life cannot be separated from the popularization and development of the mobile Internet.Among them,RFID and the two-dimensional code has been integrated into our food and clothing,brought a lot of convenience to us,and our life.However,because of the high cost of RFID and the low recognition efficiency of two-dimensional codes,we proposed color codes without chips based on color optical recognition.The high dimensional label is made up of several rectangular color blocks formed by visible light.The color code label is 90% lower than the RFID cost,and the performance is 90%higher than the two dimensional code.Color codes use visible light to complete recognition and positioning,without any electromagnetic radiation.Color codes are safe and green without any harm to the human body.In this paper,the design idea of color codes,as well as related technology and security introduction are put forward.Then the development process of color code recognition software is introduced in detail,and the algorithm of contour extraction and center point sorting is designed.Based on that,optimization and improvement are made,adding clustering algorithm and anti-jamming algorithm to solve the problem of color block migration and color code miscellaneous points.Finally,the safety performance of color code in commodity system,payment means and logistics system is analyzed.The security attack of color code application in different scenarios are put forward.Simulation attacks,network security attacks,color coded organization attacks and mobile terminal attacks are proposed,and corresponding countermeasures for each attack are put forward.Through the software development algorithm and security analysis of this paper,we theoretically guarantee the reliability of the identification technology of IOT based on color codes,and lay the foundation for the application of color codes.At the same time,it also provides ideas for further research and innovation of the color code.The main innovation points of this paper are the following points:1)This paper first studies the research of color code recognition technology for the application of the Internet of things.For the first time,the contour extraction algorithm and the center point sorting algorithm are applied to the recognition of color code,and the basic recognition function of color code labels is achieved.2)The clustering algorithm and anti-jamming algorithm are proposed to optimize the algorithm performance and ensure the reliability of color code in the case of a certain color block offset and clutter interference.3)This paper proposes and designs a new information hiding algorithm for color codes,which makes attackers unable to distinguish through the color change characteristics of secret blocks,and color code recognition software can correctly distinguish color coded pictures,thus preventing the simulation attack of color codes.
