Study of compliance of Apple's location based APIs with recommendations of the IETF Geopriv
Bibliographic record
Abstract
Location Based Services (LBS) are services offered by smart phone applications which use device location data to offer the location-related services. Privacy of location information is a major concern in LBS applications. This paper compares the location APIs of iOS with the IETF Geopriv architecture to determine what mechanisms are in place to protect location privacy of an iOS user. The focus of the study is on the distribution phase of the Geopriv architecture and its applicability in enhancing location privacy on iOS mobile platforms. The presented review shows that two iOS APIs features known as Geocoder and turning off location services provide to some extent location privacy for iOS users. However, only a limited number of functionalities can be considered as compliant with Geopriv's recommendations. The paper also presents possible ways how to address limited location privacy offered by iOS mobile devices based on Geopriv recommendations.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
