Design And Implementation Of Spam SMS Filter System Based On MTK Platform MobilePhone

In recent years,with the development of mobile communication technology and the growth of the mobile phone users,mobile phone short message also got rapid development,but at the same time types and volume of spam messages also began to overflow,seriously interfere with the user's daily life.Spam has become a problem in mobile operators and mobile users,so spam filter has become a research hot spot.Due to the high cost performance,the current based on MTK(MTK MediaTek,namely is short for Taiwan MediaTek multimedia chip providers)platform function of cell phone still occupy a lot of market share in China.And the high price of smartphones,MTK phone is very less in text filtering applications.So based on MTK platform mobile phone short message filtering system has great research value.Traditional text filtering technology is mainly based on the blacklist filtering technology and text content filtering technology to filter spam messages.Due to spam sender often change cellular phone number to send default blacklist will failure,so according to the text classification to identify whether the information interception and filtering are also very important.This paper is according to the actual needs of the mobile communication company,the MTK platform system structure and its programming mechanism is analyzed,and aiming at the shortcomings of the current message filtering technology,combining new technology with the existing technology,studied the mobile phone SMS spam filtering system design and implementation.To determine the specific function of the system module includes:insert,delete module,search module,change the function,the emptying function module,logs,keywords,etc.In order to better serve the mobile user,realize to spam filtering,this system mainly consider the way in the mobile terminal to install filtering system,by blacklist technology combined with the text classification technology,and the method of using the Bayesian classification to classify text content recognition,in the aspect of system design analyzes the blacklist filter module,keyword filtering module,such as spam recognition process.Finally in the nucleus operating system,spam filtering is achieved using ANSI C language.From the point of the current application situation,on the MTK platform development of message filter function by using this method to solve the problem of spam messages to a certain extent.
