Customizing Data Analysis Using Forensic Approach in Personalized RFID for Access Control of Student's Harmful Contents

摘要

In personalized RFID environments, we should consider about privacy, especially damages for contacting offensive contents. Currently, teenagers and even elementary school students below the age of 10 are using cell phones which are in reality ubiquitous information terminals when in fact they ought to be private devices. As such, they can access harmful contents to minors very easily. Therefore, a strict and elaborate mechanism for adult verification should be provided to protect young people from harmful contents. Despite the above countermeasure, if mobile terminals as RFID readers access harmful contents and read them, all related data such as accessing time or contents' title should be analyzed afterward for checking whether they used for accessing harmful contents or not. Since those data can be deleted by user, general analyzing methods are not useful. So, we use a forensic approach for customizing them to analyze easily. Target media such as hard disks containing related data are copied and analysts use this copy for examining related data. All related data including deleted data can be analyzed using various analysis techniques.
