The document discusses challenges facing widespread adoption of the Internet of Things (IoT). While sensor technology exists, each sensor operates in isolation and multi-sensor systems are difficult to construct. Other challenges include data quality issues, lack of ubiquitous networks, integration difficulties, need for more sensor innovation, and inadequate security for the status quo. Standardization efforts are underway but democratizing use through sensor integration, personalization, and pervasive applications remains challenging.

Has Internet of Things really happened?
- 1. Speaker: Opher Etzion Did the Internet of Things really happened? What the inhibitors are?
- 2. “There is no Internet of Things yet” 2 Sarah Rotman Epps Oct 17, 2013 The Forrester report entitled “There is no Internet of Things Yet” asserts that while much of the sensor technology exists, each sensor lives in isolation, while multi sensor system is difficult to construct
- 3. 3 Differences between the traditional Internet to the Internet of Things Topic Traditional Internet Internet of Everything Who creates content? Human Machine How is the content consumed? By request By pushing information and triggering actions How content is combined? Using explicitly defined links Through explicitly defined operators What is the value? Answer questions Action and timely knowledge What was done so far? Both content creation (HTML…) and content consumption (search engines) Mainly content creation
- 4. 4 A major difference between traditional Internet and the IoT – usability The success of the Internet is attributed to its relative simplicity: to connect to create content to search Imagine that any search in the Internet would have been done using SQL queries… How pervasive do you think the Internet would have been?
- 5. For situational awareness…. Languages are actually more complex than SQL 5 // Large cash deposit insert into LargeCashDeposit select * from Cash deposit where amount > 100,000 // Frequent (At least three) large cash deposits create context AccountID partition by accountId on Cash deposit; Context AccountID Insert into FrequentLargeCashDeposits select count(*) from LargeCashDeposit having count(*)>3; // Frequent cash deposits followed by transfer abroad Context AccountID insert into SuspiciousAccount select * from pattern [ every f=FrequentCashDeposit -> t=TransferAbroad where timer.within(10 days)]
- 6. 6 Internet of things – what’s holding us back Chris Murphy, InformationWeek, May 5, 2014 1.The data is not good enough 2.Networks aren't ubiquitous 3.Integration is tougher than analysis 4.More sensor innovation needed 5.Status quo security doesn't cut it We’ll concentrate on these topics – with special emphasis on the democratization of use
- 7. 7 Data is not good enough…
- 8. 8 State-of-the-art systems assume that data satisfies the “closed world assumption”, being complete and precise as a result of a cleansing process before the data is utilized. Processing data is deterministic In real applications events may be uncertain or have imprecise content for various reasons (missing data, inaccurate/noisy input; e.g. data from sensors or social media) Often, in real time applications cleansing the data is not feasible due to time constraints
- 9. 9 Where does the uncertainty come from?
- 10. 10 Security considerations of IoT Murder by the Internet “With so many devices being Internet connected, it makes murdering people remotely relatively simple, at least from a technical perspective. That’s horrifying,” said IID president and CTO Rod Rasmussen. “Killings can be carried out with a significantly lower chance of getting caught, much less convicted, and if human history shows us anything, if you can find a new way to kill, it will be eventually be used.” EXAMPLES: Turn off pacemakers, Shutdown car systems while driving, stop IV drip from functioning
- 11. 11 Privacy considerations of IoT The traditional Internet and social networks are already compromising privacy in the virtual world The Internet of Everything increases the challenge since it can track the physical world
- 12. 12 Democratization of use in Internet of Things Challenges: Integration of sensors and actuators Personalization of situation detection Pervasive use
- 13. 13 Standardization Standards were crucial to the success of the traditional web The “Joint Coordinated Activities on IoT” published in February 2014 standards roadmap: http://www.itu.int/en/ITU- T/jca/iot/Pages/default.aspx With aspects on architecture, format, identification, sensor network management and more… AT&T, Cisco, GE, IBM and Intel form Industrial Internet Consortium for IoT standards in March 2014 http://www.fiercewireless.com/story/att-cisco-ge- ibm-and-intel-form-industrial-internet-consortium- iot-standard/2014-03-28#ixzz32F6UB1KE
- 14. 14 Summary Much has been done on IoT There are still challenges ahead in order to make the use of IoT as pervasive as the traditional Internet.
