Abstract

The incorporation of Global Positioning System (GPS) receivers and sensors into mobile devices has enabled collaborative sensing applications, to monitor the dynamics of environments through the collection of data from many users’ devices. The automotive traffic monitoring system and alternative route selection estimates traffic congestion from GPS velocity measurements reported from many devices. This paper considers the problem of improving guaranteed anonymity in a locational data set that includes location traces from many users, while maintaining high data accuracy. A novel time-to-confusion criterion to characterize privacy in a locational data set and propose a disclosure control algorithm that selectively reveals GPS samples to limit the maximum time-to confusion for all vehicles. It also considers heading information reported by users in the tracking model to find alternative route.

Abstract

SPAM (UBE) is email sent to groups of recipients who have not requested it or have "opted out" of group email subscriptions and continue to receive email from the sender. So we devise a DKIM (Domain Key Identified Mail), which is a domain level authentication framework for email using public-key cryptography and key server technology to permit verification of the source and contents of messages by either Mail Transfer Agents (MTAs) or Mail User Agents (MUAs). The ultimate goal of this framework is to permit a signing domain to assert responsibility for a message, thus protecting message signer identity and the integrity of the messages they convey while retaining the functionality of Internet email as it is known today. Protection of email identity may assist in the global control of "spam" and "phishing".

Keywords

DKIM, Mail Transfer Agent (MTA), DNS Resolution.
