Abstract:
In some examples, geographical track data obfuscation may include ascertaining geographical data points that include a first data point and subsequent data points. For each of the subsequent data points, a delta degree value may be determined as a difference between a subsequent data point and a corresponding previous data point. A first format preserving encryption (FPE) may be applied to encrypt longitude and latitude values of the first data point. A second FPE may be applied by applying a translation of a plurality of translations to encrypt each delta degree value. A total distance traveled, a total time, and/or a total elevation gain may be extracted from the encrypted first data point and the encrypted delta degree values.
