The document discusses the implications of privacy in the context of social media and mobile technology, highlighting issues such as data harvesting, location tracking, and the confusion surrounding app privacy policies. It emphasizes the need for both consumers and businesses to take personal responsibility in managing privacy and security, while also noting the challenges related to regulatory frameworks. The presenters advocate for a new paradigm where consumers actively read and understand privacy policies, and businesses implement better data protection practices.

5. Privacy in a Mobile World
• Mobile Data: Storage
– Mobile devices have become
“virtual wallets”
– Personal data via social
networks and email are easily
stored and shared with
others
– Smartphone are personal
tracking devices that just
happen to also take phone
calls
– Smartphones are one
expensive wallet to lose!

6. Example: Mobile Pen Test

8. Trivial to Access Private Data
• With physical access…it’s “game over”
– Rooting or Jailbreaking of the device
– Passcode bypass (iOS 7- several!)
– Circumvention of “remote wipe” controls
– Malware can harvest personal data
(especially on Android)
* Subject to the security policies or MDM (Mobile
Device Management) enforcement!
8

9. Example: MyFitnessPal
• Application stores (too much) PPI on the device

10. Phone Stored Data
Date of Birth

11. Mobile Data: Transmission
• Do you know what your apps are sending?
– To the app developers?
– To third-party ad/marketing companies?
• Do mobile apps send your data securely?
– Is SSL being used?
– In our research of the Top 20 Apps…very few use SSL!
11

12. Example: UDID
• What is UDID?
– Unique Device IDentifier for the hardware
– Apple iOS (iPhone/iPad)
• Found to be transmitted from mobile apps
– To third party ad and marketing companies
– To the mobile app company
– Usually transmitted with other personal information
(user name, IP, geolocation, etc.)

17. 1 Million UDIDs Exposed?
• Hackers said it’s from the FBI. FBI denies…
• This was actually a third-party breach!
17

18. Location Based Services
• Also known as “geolocation”
• Coordinates are frequently
sent via third party services
• GPS coordinates sometimes
stored locally or sent back to
the company
• Apple had a problem with
storing location data without
user approval in 2011
18

19. Apple iOS Location Data Storage Issue
• Fixed in iOS 4.3.3
– When turning off location services, iOS will not store
or back up this data
• Some researchers created a cool tool to demo this
– http://petewarden.github.com/iPhoneTracker/

20. Facebook Timeline and Graph Search
• Easier then ever to view where someone has been
• Pulls location data from photos, status updates and
more…
20

21. Instagram Photomaps
“…you can now much more easily access
photos you and others took months or
even years ago.”
– Kevin Systrom, co-founder and CEO of
Instagram

21

22. Address Book Harvesting
• More apps are doing this
• “See if your friends are using this app”
• Apple iOS apps could access contact
data without permission (fixed in iOS 6)
• Install prompt on Android
• Developers can notify you on their
own…

• Takes your:
– Address book
– LinkedIn contacts
– Facebook Friends List
– Who you follow on Twitter
– Gmail address book
– FourSquare Locations

29. Apple “Find and Call Malware”
• First “Trojan” for Apple iOS?
• It was a spammy app that sent
your contact list to a third-party
server
• Your friends get SMS spammed
from the server
• App removed from the App
Store and Google Play

30. New Tech: Shopper Tracking
• Uses your active WiFi “beacons” to identify you by your
MAC address
• Google Analytics for “People”

31. Evolution: Social Media Integrated into Mobile
Operating Systems
• Apple iOS 5 – Twitter integrated into the OS
• Apple iOS 6 – Facebook integrated into the OS
• Apple iOS 7 – Pretty interface integrated in OS

33. Evolution: Google Now and Passbook
• Google Now: “Predicts” things
based on your location and actions
you take on your device
• Weather, what’s the traffic like on
your way to work?
• Passbook: Actions are taken when
you enter a location: IE: Enter a
Target, coupon pops up

38. Generally Accepted Privacy Principles
38

39. Privacy in the Wild
• Notice – 6,867 word Privacy Policy (LinkedIn, 10-14-13)
• Consent – IF offered often buried down 19 screens
• 3rd Party access (service provider in China? Pakistan?)
– Hey you “consented.” It was on the 19th screen!
• Collection – Some collect too much (MyFitnessPal)
• Retention – Not typically addressed in the US
• Disclosure to 3rd Parties – Almost unilaterally!
• Security – Who knows (more on that later)
• Quality – I loaned my phone to my son. I never went…
39

40. Privacy Policies

41. Privacy Policies
• Notices Bottom Line
– Painful to read, so no one reads. We have no idea
what we agree to, I just want to play Angry Birds Star
Wars 2…
41

42. 42

43. Government Data Requests
• Policies almost unilaterally allow sharing with authorities
– Per Washington Post (as of 9-6-2013)
– Yahoo responded 12,444 requests for data from
the U.S. government YTD
– 40,322 users
– YTD Yahoo has rejected 2% of the requests

43

44. Government Data Requests (con’t)
• Google, Facebook, Apple, Microsoft
– Foreign Intelligence Surveillance Act
– National Security Agency
– Foreign Intelligence Surveillance Court
• Sought to release data on the requests they receive
from government agencies to release consumer data
– Take away: Data is being collected and subject to other
possibly accessing. In the US it may NEVER be deleted!
44

45. More Privacy Control = More Confusion
• Consumers:
– Take initiative to read the Policies
– Understand the legalese Policies
– Need to act to protect PPI/PHI
• Businesses :
– Google munged 60 Privacy Policies into 1!
– Opt out check-box is 11 pixels wide!
– No incentive to manage if consumers don’t care!
45

46. Mobile Apps
(where’s the security indicators?)
46

47. Privacy in a Social World
• Facebook,
Twitter and
LinkedIn have
grown
exponentially!
• 900 Million!
• Privacy issues
have increased
as well
• Mobile users to
top 8 billion by
2016 (1)

49. Hot New Tech: Facial Recognition
• “Facedeals”
– Camera real-time matches face to Facebook
– Matches get discounts sent to smartphone
49

50. Fiction: Minority Report
50

51. Reality: Disney’s MagicBands (MyMagic+)
51

52. Google Glass
• Camera inconspicuously imbedded in glasses
– Pictures and stream video to social networks
• Already banned in a Seattle Restaurant (5 Point Cafe)
– What about at airports (TSA Security check points)
– School yards
• Smartphone and
video cameras
52

53. 53

54. Privacy Ramifications
• How to deal with new technology
– e.g., Facedeals, MagicBands
• Opt out of facial scans?
• Misuse of technology!
• Tracking children
• Apple Passbook
– iPhone = your wallet
• Digital coupons, tickets, loyalty cards
• Allow payment with near field chip (NFC).
• GPS detects your location and presents coupon
• Malware
– Nefarious data extractions
• GAPP
– Can we really apply Privacy Principles?
54

55. Regulatory Ramifications
• International
– Appeasing the law patchwork
– You think 6000 word Policy is long
• Read one that addresses 10 countries!
• Now reading page 1 of 101
• United States
– Data aggregation and correlation not
addressed in US law.
• We want ease, we will sacrifice privacy,
until it’s too late.
55

56. On the Horizon
•
•
•
•
•
US Businesses will collect more data and retain
Technology will better correlate data
Consumers won’t read privacy policies (have you?)
Breaches will continue unabated
New federal encompassing privacy regulations unlikely
– Mobile device data regulations may be looming
• Technology outpace regulators
• More data in the cloud
56

57. New Paradigm
• Consumers
– Personal responsibility
• Read Privacy Policies and Security Safeguards
– Choice
• Select businesses based on privacy
– Cognitively execute your preferences
– Correct the accuracy of the data, not just when
getting a loan (e.g., HIPAA, GLBA, credit bureaus)
– Limit the data you provide
(do they really need it?)
57

58. New Paradigm
• Businesses need to rethink business model
– Capture less data, retain shorter durations
– Adopt GAPP principles
– Better data protection
– De-identify data
– Strong encryption
• Security/Privacy Professionals
– Be aware of the risk – Bad things will happen!
– Formally Document the risks for management
– Share the risk! (e.g., Annual Risk Posture Statement)
– Be a Champion of Privacy and Security
58

59. Closing Thoughts
• Short federal law migrating towards EU Privacy
Directive, big business will collect and retain all
the data they can gather, including passive data
sources we discussed.
• Security/Privacy professionals, businesses, and
YOU the consumer must be proactive in
managing our digital footprints.
• Collective responsibly!
