Evaluating the Performance of a Spatial Scan Statistic Using Simulated Outbreak Characteristics
Content Type: Abstract
Research evaluating the use of spatial data for surveillance purposes is ongoing and evolving. As spatial methods evolve, it is important to characterize their effectiveness in real-world settings. Assessing the performance of… read more… outbreak data (signal) into actual background visit data. These studies focused on either temporal data, a … synthetic outbreak data (signal) into actual back- ground visit data.1,2,3 These studies focused on either temporal … and longitude using ESRI ArcGIS 8.3. For each week of visit data we used a cluster creation tool4 to insert one of … -
Anonymization of Spatial Data by Gaussian Skew: Is Re-Identification Possible?
Content Type: Abstract
To evaluate the robustness of a spatial anonymization algorithm for syndromic surveillance data against a triangulation vulnerability attack. `BACKGROUND We have published an anonymization algorithm that takes precise point locations for patients… read more… data requests. Obfuscative and cryptographic algorithms may be susceptible to weakening when it is possible for an … they are requested, triangulation of original addresses may be possible or the anonymity afforded by the algorithm may be reduced.

A Novel, Context-Sensitive Approach to Anonymizing Spatial Surveillance Data: Impact on Outbreak Detection
Content Type: Abstract
The use of spatially-based methods and algorithms in epidemiology and surveillance presents privacy challenges for researchers and public health agencies. We describe a novel method for anonymizing individuals in public health datasets, by… read more… set- ting. METHODS Cases were emergency department (ED) visits for respiratory illness. Baseline ED visit data were in- jected with artificially-created …
