                      ***** CALL FOR PAPERS *****

Theme of the Workshop

Combining the functionality of location-aware devices, wireless and
cellular phone technologies, and data management results in enabling
a new era of location-based mobile services that aim to provide personalized
services to their customers based on their current locations. Examples of
such services include location-aware emergency service, location-based
advertisement, live traffic reports, and location-based store finder.
Although location-based services promise safety and convenience, they
threaten the privacy and security for their customers as they rely mainly
on the knowledge of their customers' location information. The current
model of location-based services trades the customers' privacy with the
service. If a user wants to keep her private location information, she
has to turn off her location-aware device and temporarily unsubscribe
from the service. Recent social studies show that customers become more
privacy-aware as they tend to avoid using location-based services in order
to keep their privay. As a result, there is a real concern that the privacy
issues may hinder the technological advances in location-based services.

Workshop Goals

Location privacy is a cross cutting area as it crosses social science,
communications, location-based services, databases, and security.
The main goal of the workshop is to gather scientists from these areas
together to foster the collaboration among such interdisciplinary areas
and sparkle discussion on open topics related to location privacy.

The workshop aims aim to address the location privacy from different
aspects, starting from social studies of users concerns, going through
different models of representing location privacy, location anonymization
techniques, imprecise locations, query processing for private or imprecise
location data, and ending with a study of various attack models for
private location data. The workshop aims also to discuss location privacy
in various environments that include using GPS, RFID, or sensor networks.
The workshop will be organized in a way to allow close interaction among
participants and to sparkle discussions and thoughts among various research
communities.

Workshop Scope

The scope of this workshop includes but is not limited to the following topics:

• Context-aware privacy
• Location data publish models
• Location-based Services with location privacy
• Imprecision in Mobile Computing
