Research On Privacy Protection Of Electronic Coupons For Mobile Application

Nowadays,with the rapid development of the mobile e-commerce community,many of the Internet-related services such as stock exchange,online shopping and banking are becoming an indispensable part of people's lives.Most consumers use online payment,and electronic offers Coupons,there is no doubt that the consumer groups to bring convenient benefits,a wide range of electronic coupons,more and more people will use electronic coupons when shopping,but with the network information security is becoming increasingly serious.There have been a lot of theft from the private information and financial events,so people extensively study the certification program and key agreement agreement.In this paper,we focus on the network security problem in the electronic coupon environment,and propose a one-time password authentication scheme based on biometrics.We use the method of biometrics authentication technology and one-time password to build electronic coupon environment of the network key protocol.First of all,through a brief introduction to basic theoretical knowledge,we know that biometric technology has a unique and irreplaceable characteristics,and the acquisition of biological characteristics of the very low cost,one-time password allows users to log in the process of adding more unpredictable Of the factors,the use of hash function to build the key,to avoid many consumption algorithms,so as to consumers identification and authentication provides a huge security,effectively prevent the attacker through a variety of illegal ways to achieve high reliability sex,efficient electronic coupon system.In this paper,the key aspects of the key protocol are described in detail.The algorithm steps are given in detail,including the registration stage of the electronic coupon for user,the release stage of the electronic coupon,the download stage of the electronic coupon,the update stage of one-time password.Then gives the security analysis and efficiency analysis,and finally summarizes the key agreement in the electronic coupon environment and prospects the network key agreement.
