Location Privacy in Spatial Crowdsourcing
Spatial crowdsourcing (SC) is a new platform that engages individuals in collecting and analyzing environmental, social and other spatiotemporal information. With SC, requesters outsource their spatiotemporal tasks (tasks associated with location and time) to a set of workers, who will perform the tasks by physically traveling to the tasks’ locations. However, current solutions require the work...
متن کاملInstance-Privacy Preserving Crowdsourcing
Crowdsourcing is a technique to outsource tasks to a number of workers. Although crowdsourcing has many advantages, it gives rise to the risk that sensitive information may be leaked, which has limited the spread of its popularity. Task instances (data workers receive to process tasks) often contain sensitive information, which can be extracted by workers. For example, in an audio transcription...
متن کاملProtecting Location Privacy in Spatial Crowdsourcing using Encrypted Data
In spatial crowdsourcing, spatial tasks are outsourced to a set of workers in proximity of the task locations for efficient assignment. It usually requires workers to disclose their locations, which inevitably raises security concerns about the privacy of the workers’ locations. In this paper, we propose a secure SC framework based on encryption, which ensures that workers’ location information...
متن کاملPreserving User Location Privacy with Safe Zone for Spatial Queries
Now a days the use of Location Based Services (LBS) gained importance among the users. In most of the cases, users do not want to reveal their personal information to their service providers. Sometimes mobile devices are out of the specified range which cannot be processes by servers. Hence confidentiality, privacy and up to date and optimal answers will be important aspects in location based s...
متن کاملPrivacy-Preserving Location Publishing under Road-Network Constraints
We are experiencing the expanding use of location-based services such as AT&T TeleNav GPS Navigator and Intel’s Thing Finder. Existing locationbased services have collected a large amount of location data, which have great potential for statistical usage in applications like traffic flow analysis, infrastructure planning and advertisement dissemination. The key challenge is how to wisely use th...
