Research And Design Of Mobile Payment Security Risk Assessment System

In recent years,the rapid development of mobile payment has become a major form of payment.Safety and reliability are the primary risks faced by mobile payment users during use.With current network conditions,there are risks even if you use any security precautions.Therefore,it is necessary to do a risk assessment of its safety.Based on research done at home and abroad,proposed a Mobile Payment Security Risk Assessment Model Based on Improved Gray Analytic Hierarchy Process(IGAHP-MPSRAM),mainly completed the following aspects of the work:Firstly,Creating a risk assessment index system.Summarizes the issue of mobile payment security and research existing risk index system set,combined with the construct method of index system,analyze the risk factors,establish the targeted and reasonable security risk index system.Secondly,Establish and apply an assessment model based on improved AHP and Grey theory.Because traditional risk assessment algorithms are relatively simple and lacking innovation,the process of calculating index weights is troublesome proposed an improved AHP method.The improved AHP method can not only simplify the calculation process,but also take into account the subjectivity and objectivity existing in the risk assessment process.Due to the uncertainty and fuzziness of mobile payment,an evaluation model was created by combining improved AHP method with Grey theory.The model is applied to the actual mobile payment system,which confirms that the evaluation model has a certain practical value,and verifies that the research can accurately obtain the system's security risk status,and can provide a reference for the system to do risk prevention and determine the safety control measures.Thirdly,Design and develop a risk assessment system.Based on the risk assessment model mentioned above,a mobile payment security risk assessment system based on the IGAHP risk assessment model was developed to provide the assessor with an easy-to-use,user-friendly assessment tool.
