Privacy-aware collection of aggregate spatial data
Privacy concerns can be a major barrier to collecting aggregate data from the public. Recent research proposes negative surveys that collect negative data, which is complementary to the true data. This opens a new direction for privacy-aware data collection. However, the existing approach cannot avoid certain errors when applied to many spatial data collection tasks. The errors can make the dat...

متن کاملDistributed Privacy Preserving Data Collection
We study the distributed privacy preserving data collection problem: an untrusted data collector (e.g., a medical research institute) wishes to collect data (e.g., medical records) from a group of respondents (e.g., patients). Each respondent owns a multi-attributed record which contains both non-sensitive (e.g., quasi-identifiers) and sensitive information (e.g., a particular disease), and sub...
متن کاملQuality-aware sensor data collection
Many sensor applications often require to collect raw sensed values from many sensor nodes to one centralized server. Sensor data collection typically comes with various quality requirements, e.g., the level of precision requested for temperature values, the time constraints for getting the data, or the percentage of data that is needed. This paper presents a quality-aware sensing framework whe...
