In this paper, the authors propose a personal portable proxy server that offers various functions from a USB flash drive. With the rapidly growing volume of data generated by applications, managing that data becomes a problem. A USB flash drive can help the users manage data easily, because they can carry any data and any application anytime on a USB flash drive. Therefore, they propose an intelligent personal proxy server with personal functions on a USB flash drive. This intelligent proxy provides convenient features, such as content filtering, history sharing, phishing prevention, and especially automatic form completion.
