Preventing Location-based Inference Attack in Location Based Services
2012 International Conference on Industrial Control and Electronics Engineering, 2012The query privacy issue in location-based services (LBS) has recently received considerable attention. To protect the query privacy of users, current state-of-the-art techniques adopt cloaking which cloaks the sender's location to k-anonymized spatial region (ASR), such that an attack based on the sender's location cannot identify the query source with

Location Based Notification System
2018 International Conference on Research in Intelligent and Computing in Engineering (RICE), 2018In this paper, an Android Application is created for location reminder and friendly suggestion. When a friend comes nearby 1 km area then the user gets notified on mobile. When a user sets location on a map and if a user enters that marked area then the mobile will start its alarm.

Enabling location-based applications
Proceedings of the 1st international workshop on Mobile commerce, 2001We identify a number of factors that may hinder the commercial success of location-based applications: the concern of privacy, the need to consider context beyond location, the presence of voluminous resources, and the constrained interfaces available on mobile devices.

Flexible Location-Based Spatial Queries
2007A model for representing and evaluating flexible Location-Based Spatial Queries (LBSQ) is proposed. In a LBSQ the selection condition is generally a constraint on the distance of the objects in the database (instances) from the user location. Such queries are becoming more and more useful in location-based services such as those provided by cell-phones,

Semantic location-based services
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Semantic location-based services (LBS) aims to provide intelligent LBS that can find and integrate various information to better meet user requirements in location-aware context. This paper argues that traditional approaches for semantic GIServices in the Cyberinfrastructure context could be extended into the LBS.

Crowdsourcing location-based queries
2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops), 2011Location-based queries are quickly becoming ubiquitous. However, traditional search engines perform poorly for a significant fraction of location-based queries, which are non-factual (i.e., subjective, relative, or multi-dimensional). As an alternative, we investigate the feasibility of answering location-based queries by crowdsourcing over Twitter ...

Location-based Publish/Subscribe
Fourth IEEE International Symposium on Network Computing and Applications, 2005This paper introduces the concept of location-based publish/subscribe (LPS), which allows mobile ad hoc applications to anonymously communicate with each other, depending on their locations. With this concept, publish/subscribe topics are typically expressed in a dynamic manner including proximity criteria, e.g., "I subscribe to all events on topic T ...

Location-based prospective memory
Quarterly Journal of Experimental Psychology, 2018This study explores location-based prospective memory. People often have to remember to do things when in a particular location, such as buying tissues the next time they are in the supermarket. For event cognition theory, location is important for structuring events. However, because event cognition has not been used to examine prospective memory, the

2018 10th International Conference on Virtual Worlds and Games for Serious Applications (VS-Games), 2018
This poster presents a novel type of Virtual Reality (VR) application for education and culture: a location-based VR Museum, which is a large-room scale multi-user multi-zone virtual museum. This VR museum was designed to support over 100 simultaneous users, walking in a large tracking system (600 m2) and sharing a ten times bigger virtual space (7000 ...
