Motivation

Population ageing Demographics of Germany

Increasing Life expectancy & Declining birth rate (~1.4 children born / woman)

Next 50 years: Increase of people aged over 65 from 19% to over 30% [1]

Next 20 years: Increase of people in need of medical care by 58% [1] Not limited to Germany, e.g. Japan, Italy, Spain

Increase in healthcare cost and annuity More people in need for medical care, less people to provide medical care

Ambient Assisted Living (AAL) Increase quality of life, safety and social integration of elderly people Technologies for providing unobtrusive support in everyday life situations Reduce cost of health care

SmartAssist Service Platform

Platform to support a self-determined and safe life for elderly people / Seniors

Needs-based care in their own home through personal Patrons Instead of (early) submission to a nursing home

Basic Idea Social Network Remote monitoring through in-home wireless sensor network

Slide 5

Page 6: Privacy concerns in a remote monitoring and social networking platform for assisted living

Seniors

Age: 65 years+ and retired Spend large amount of time in their own apartment Mentally fit (Still) Capable of independent and self-determined living

Two groups (taken from [5]) People interested in preventive care (Group 1.1.3 in [5])

Early detection & diagnosis of diseases and disabilities People in need of assistance (Group 1.2 in [5])

Use of third party services

Patrons

Care for Seniors provided through personal Patrons Relatives Friends Medical Personnel (Doctors, Ambulances) Third Party Service Providers

Three groups (taken from [5]) Caregivers or Healthcare assistants (Group 2.1.1 in [5])

Children, grandchildren, siblings, close friends and neighbours Medical personnel (Group 2.2 in [5])

Doctors, Physicians, Paramedics Third Party Service Providers (Group 2.4 and 3.8 in [5]

Security companies, home care providers, ambulance services

Existing Health Websites

Eons.com Social Network for elderly people: Photo and Video sharing Interviews and Articles on Topics like Health, Relationships, Fitness, Dept,

Retirement, Insurance, …

PatientsLikeMe.com / DailyStrength.com User User: Emotional Support & Strategies Sharing same diseases / disabilities / problems in life Symptoms & Experiences with Treatments

MedHelp.org Discussion board on health related topics Cooperates with Doctors Visited by 10 million people each month (self proclaimed)

SmartAssist Platform Components

Monitoring Unobtrusive environmental/ambient sensors Sensor readings forwarded to a central server Signal processing and pattern recognition: Daily routine and activities

Social Network Communication between the users and their patrons Stronger social integration (across distances) Knowledge transfer between seniors (Interest groups, local community events,

…) Social data used to augment sensor data for medical (e.g. Status messages

about feelings, stress, tiredness, headache, …)

Services Extensions to the platform through „Plugins“ Comparable to “Android Market” / “App Store” for mobile phones

Examples (from sensor readings)

Low room temperature in Winter: Is the Senior feeling hot? (Fever, Shivering) How much time does the Senior spend in the bedroom? Is he very sleepy? Does the Senior forget to turn off the lights? The coffee machine? How often does he use the bathroom? Does he wash is hands after using the toilet?

(Lowered personal hygiene can be an indicator for Alzheimer Disease)

What we try to do Combine Social and Sensor information Monitor and analyse the daily routine Help Patrons watch over Seniors Help diagnose subtle changes in behaviour Try to detect dangerous/emergency situations and send help (Third

Party/Patrons)

What we can’t do Prevent the user from admission to a nursing home Guarantee for Emergency assistance

Lots of Sensitive Information

Generation Seniors enter private information in the social networking component Sensors automatically generate private information Signal processing generates sensitive information (e.g. activities)

Transmission All information needs to be transferred using encryption Protection against eavesdropping and man-in-the-middle attacks Integrity and Authenticity protection

Storage & Access Availability Integrity and Authenticity Access Control Logging

Issues to deal with

The Senior is in control of all of his information View all data, Edit and Delete all data Sensors can be switched on and off at any time (and scheduled)

Seniors need to be in control who has access to their data (restrictive by default)

Controllable on user and patron/group level Accessible and understandable Possibility to provide different and even forged information “Who has accessed my information?”

Sharing of information needs to be voluntary No monetary or legal force No disadvantages for insurances

Information Sparseness Only necessary information needs to be collected and stored Resolution, sample rate, Fuzziness Similar to “Selective Availability” in GPS (Global Positioning System)

Future Work

Illegal access to sensor data Analyse when the user is not at home, plan a burglary accordingly

(www.pleaserobme.com) Identity Theft: Taking names, addresses, photos Sensor Data Theft: Pretend to be a healthy senior and commit insurance

fraud

The right of Not-Knowing / nescience Given: Diagnosis of a serious disease Should the Senior be informed? Should the patrons (a doctor) inform the Senior? Make information unavailable to insurance companies

Alteration / Deletion of data Interfere in the detection of a disease (Inheritance / Life insurance) Protection against physical tampering Maintain the right for virtual tampering (fuzziness), but detectable
