Research Of Information Extraction Technology Based On Symbian OS

In the times informationize more and more quickly now, Mobile phones have been much more than the Talk Tools only receiving and dialing the calls, in the 3G which already arriving in, data business specific gravity escalation , information communication already occupy important position as moving terminal information exchange way. Intelligence mobile telephone already melts as a kind of to enter people the daily life role, the daily consumer information be stored on mobile telephone is really the most precious wealth of intelligence mobile telephone.This paper first introduced ths Symbian OS development platform's relevance knowledge and the development key technology. Then explained the Message Architecture, research the operation such as admitting , drawing , dispatching having realized the short message and email under Message Framework. Then studyed in a deepgoing way a few daily consumer information's operation such as: contacts, communication Log, calendar, document listing, and realized the operation of these information such as drawing , admitting and so on.This paper researched and realized the operations under Symbian OS such as Socket Communication and so on. Firstly detailed the elementary knowledge about Socket's system structure and core function class; secondly deep researched and realized the Host resolution services and Internet Access Provider technology; then detailed the operation about Socket Communication under Symbian OS with procedure example; finally, describes the operation of PC client socket code processes and procedures based on the introduction of relevant knowledge about PC client's socket connection.This paper finally programming The Remote Forensics System Based on Smartphone, after repeated the testing and improving; now it has good character,operates stably,attains the aim of system development. The success of The Remote Forensics System Based on Smartphone not only supplies a platform for extracting and transmitting information on smartphone, but also gives great help to smartphone Forensics.
