Anonymous location and speed information from the
TomTom user community
5 billion (10E9) speed measurements per day
5 trillion (10E12) speed measurements to date!
by customers driving 50 billion kilometres
and visiting every spot over 1,000 times

10. Origin/Destination analysis
Example: Trips with Frankfurt Airport as destination
• Where are your
customers coming
from?
• What routes do they
take?
• How may drivers are
passing?
• Etc.
• Combine with other
geo-based data
sources for additional
analysis

11. Location privacy is top of mind
With bloggers, press, regulators, enforcers, legislators and many
users
• TomTom investigated by
leading European Data
Protection Authority in 2011
• TomTom’s use of location
data is in accordance with
EU Data Protection Laws
• Processing and delivery to
third parties 100% OK
• Informing users needed to
be more explicit, including
opt-in
11
13. Privacy, amongst others, is about the
protection of personal data
Personal data:
• Contains (whatever) information
relating to a natural (“real”) person
• That person could be
identified, directly or indirectly
• Typically: data attached to unique
identifiers
Anonymous only:
• When no reasonable way exists to
identify (“single out”) a person
• Even when requiring correlation with
other data sources (e.g. maps and
phonebooks)
• By anyone with the right resources
13
14. EU WP29 opinion “Geolocation services on smart mobile devices”
Beware: engineers’ “binary” interpretation of principle based law with open norms
• Data attached to a unique identifier (e.g. serial number, email address) or reversible
pseudonym (e.g. a hash) is to be considered personal data
• Location data originating from any individual is to be considered sensitive personal data:
consent is the only acceptable legal basis for processing
• Sending location data “off board” requires:
• Freely given no pressure is felt to consent
• Prior before processing starts
• Informed explain purpose, duration and who has access
• Explicit i.e. opt-in requiring a user action and separate from accepting T&C’s
• Consent permission to go ahead
• Information is required regarding:
• What data is processed
• Who will have access
• Why is the data used
• When will it be deleted
• Where will the data be processed
• Validity of consent is directly related to the quality of information towards the user
• Consent renewal is required after prolonged period of non-use and at least every year
• No feature creep: perfectly stick to the purpose as agreed to by the user
• Erase location data right after use and never keep longer than 24 hours
14
15. Typical personal data misconceptions
very often present in technology companies
• We do not identify the user while using the data, so we have no
issues with privacy law
• We only use the unique serial number of the users device, so
the data is anonymous and we have no issues with privacy law
• We encrypt the data, so we are no longer
using/receiving/sending personal data
• We use hashes to replace all serial numbers, so the data is now
anonymous and we have no issues with privacy law
• We anonimize the data, so we are not using personal data
• We can use the users’ data for anything we want, as long as we
keep the data to ourselves
• Look: big name companies are doing the same, so we are OK

16. TomTom & Privacy
Vision: Principles:
Community input (crowd 1. Avoid unpleasant surprises:
sourcing) is strategic • Customer insight is
paramount
Privacy helps to realize business • Be open and explain –
objectives by ensuring trust hesitation is an omen
• Keep it simple
Privacy is integral part of business 2. The customer remains in
continuity above and beyond legal control of his personal data: we
compliance have it “on a loan”
16
17. Avoiding re-identification is key
TomTom has a strict code of conduct to adhere to privacy laws
1 month • Historic trip archive only
to be used for road,
traffic and related
purposes
• No access to raw data
outside TomTom, ever
• TomTom performs
1 day processing
• TomTom ensures re-
identification is
impossible e.g. through
sufficient aggregation
17
20. Recommendations
• Incorporate data protection requirements from the start
• Take a multi-disciplinary approach: it is about your
“license to operate in the information society”
• Embed “privacy by design” into development processes
• Document your data: “what, why, when, who, where”
• Appoint a “privacy czar” in your organization
