16. Security
Is the data
protected from
theft, leakage,
spying or attacks?
What is the level
of control and
protection?
Residency
Where is the
data stored?
geographically
disbursed?
What to do with
data in transit &
outside territory?
Privacy
Who can see
personally

information (PII)?
Storing,
transferring,
locating and
protecting PII

20. REGULATING CROSS-BORDER FLOWS
OF PERSONAL DATA: HONG KONG
Our current protection for personal data transferred
overseas is out-of-date (since 1995), weak and
incomprehensive
• Personal Data (Privacy) Ordinance prohibits all
transfers of personal data 'to a place outside Hong
Kong‘ (section 33)  never brought into force
Time to review and renew

21. BIG DATA AND E-GOVERNMENT
New Digital 21 Strategy:
“Smart City” vision
• Turning data analysis
into informed decisions
and intuitive services
• Internet of Things:
Sensors, e-commerce
transactions, weather
