EPHEMERALITY IS THE NEW BLACK
OVERVIEW
▸ how location privacy can be realised in the context of a location-based service
▸ discuss several measures to integrate location privacy into LBS
▸ investigate the role of location data management in the context of privacy preservation
▸ propose an approach based on privacy-by-design principles (ephemerality)
▸ introduce a conceptual model to facilitate the implementation of those principles
4
EPHEMERALITY IS THE NEW BLACK
LOCATION INFORMATION
▸ share location data
▸ respond to the requests of users according to their physical location
▸ more user-friendly
▸ issues regarding location privacy
5
EPHEMERALITY IS THE NEW BLACK
REAL TIME

EPHEMERALITY IS THE NEW BLACK
PAST DATA
7
EPHEMERALITY IS THE NEW BLACK
COUNTERMEASURES
▸ regulatory strategies
▸ agreements
▸ encryption
▸ anonymization
▸ obfuscation
8
EPHEMERALITY IS THE NEW BLACK
WHY SHOULD WE STORE LOCATION DATA?
9
FOREVER?
EPHEMERALITY IS THE NEW BLACK
UNLIMITED STORAGE TIME OF LOCATION DATA
▸ legal requirements
▸ insight for improvement
▸ deep profiling
10
EPHEMERALITY IS THE NEW BLACK
UNRESTRICTED AMOUNT OF TIME TO CARRY OUT ATTACKS
11
HOW SHOULD LOCATION INFORMATION BE STORED?
EPHEMERALITY IS THE NEW BLACK
EPHEMERALITY
▸ from Greek εφήμερος – ephemeros, literally "lasting only one day”
▸ ephemeral location data
▸ exiting only briefly
12
EPHEMERALITY IS THE NEW BLACK
TEMPORAL EPHEMERALITY
▸ consider how long location information is stored
▸ expiration time & discarding
▸ no future attack
▸ better protecting the location privacy
13
EPHEMERALITY IS THE NEW BLACK
SPATIAL EPHEMERALITY
▸ where location information is stored
▸ well-defined spatial area
▸ needs the presence of attackers or their proxies

pros cons
increases the control over user’s location privacy challenges advance analysis
flexible to combine with other methods
business related implication
no modification negative effect on commercial values

EPHEMERALITY IS THE NEW BLACK 21
would users be willing to pay for a service with
increased privacy to compensate for reduced
revenues of service providers?
EPHEMERALITY IS THE NEW BLACK
CONCLUSIONS ▸ role of location data management in the context of privacy preservation
22
EPHEMERALITY IS THE NEW BLACK
CONCLUSION ▸ role of location data management in the context of privacy preservation
▸ concept of temporal and spatial ephemerality as a means to improve location privacy in the context of a location-based service
23
EPHEMERALITY IS THE NEW BLACK
CONCLUSION ▸ role of location data management in the context of privacy preservation
▸ concept of temporal and spatial ephemerality as a means to improve location privacy in the context of a location-based service
▸ model supports the realisation of different privacy protection mechanisms and enables an explicit and fine-grained control of location data management in the context of privacy preservation
