Design And Implementation For Online Activation Management System Of Electronic Blackboard

With the rapid development of information technology,its importance in various fields is increasingly prominent.Through research and practice,our school has developed an intelligent electronic blackboard system and gradually popularized it to the market.The emergence of the intelligent electronic blackboard is favored by all kinds of schools because of its functions such as pen writing,eraser,drawing and electronic resource display.However,in the early research process,we found that there are some problems in the activation process of the electronic blackboard.The activation mode of the original electronic blackboard system is offline activation,that is,the electronic blackboard is activated by offline activation tool.The disadvantage of this activation method is that all activation operations are completed on the electronic blackboard,and the key leakage is easy to occur in the activation process,which leads to the electronic blackboard system being cracked.In addition,offline activation has some problems such as low activation efficiency and tedious operation.This paper discusses the design and implementation of the online activation management system of the electronic blackboard.It analyzes and solves some problems in the process of activating products in the promotion of the electronic blackboard.Its main contents include the generation and management of the registration serial number,the activation of the electronic blackboard,and the information submission and activation verification of the client.This paper introduces the key technologies used in the process of online activation of electronic blackboard,including C# language,SQL Server 2012 database,and visual studio 2010.In addition,this paper analyzes the rijndeal encryption and decryption algorithm used in the online activation process,focuses on the rijndeal encryption and decryption principle and process,and applies it according to the situation of electronic blackboard products.In the process of system design,the client sends the hardware information and registration serial number of the electronic blackboard to the server.Through the construction of web service,the hardware information is encrypted automatically by using encryption program,and the activation key is generated.The activation code is sent to the client through the network protocol for activation.In addition,the management end generates,sells and manages the registration serial number of the electronic blackboard.When the client has no network connection,The management end encrypts the hardware information of the electronic blackboard to generate the activation code through the offline activation function.The client verifies the activation of the electronic blackboard from the client,generates the activation file,and completes the activation of the electronic blackboard.The realization of online activation management system of electronic blackboard greatly improves the efficiency of activation and the safety in the process of activation,which is of great significance to the promotion and application of electronic blackboard system.
