The Future of InformationIts Changing Role in Society Ashok K. Agrawala Director, MIND Lab Professor, Computer Science University of Maryland
“Information is not knowledge” • Albert Einstein “… the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as through it has an underlying truth.” • Umberto Eco What is information??
Two Basic Entities • Energy/Matter • Information
Traditionally • Information => Power • He who has information has power • Controlling flow of information => Controlling population
Information • Plays a critical role in all decision making/actions • Available Information • Storage • Accessible Information • Transport and Access Methods • Useful Information • Selection Process – What question to ask? • Security and Protection
Aspects of Information • Information • Production/Reproduction/Collection/Recording • Storage • Transfer • Accessibility • Duplication • Security and Authentication • Trust in the authenticity • Meaning ?? • Technology has always played a key role. Its form has been different at different times. • Relative costs have changed substantially
Impact of changes in Costs • Form • Human Memory • Stone • Paper • Film • Digital • Punched cards • Tapes • Cassettes • CD – DVD – CMOS • … • Production/Collection • Storage • Transfer • Accessibility • Duplication • Security and Authentication
Information Past • Production/Reproduction • Human • Large Capacity • Automatic Input/Output • Unreliable Recall • Distortions – Intentional/Unintentional • Transfer • People Movement • Communication Through a natural language • Accessibility • Local • Copying/Reproduction?? • Security/Authentication • Physical Security of humans • Trust in the Authenticity?
InformationPast • Form • Typically on paper • Files • Books • Libraries/Archives • Accessibility • Difficult • Filing Systems • Catalogs • Systematic arrangements • Production/Reproduction • Handwritten • Printed • Duplication • By hand • Photocopying • Cost ???
Information Past • Storage • Paper • Handwritten • Printed • Books/Files/Reports/… • Libraries • Transfer • Physical Movement of Paper • Postal System, etc. • Accessibility • Catalogs • File indexes • …
InformationPresent • Form • Encoded as bits, bytes, words, records, etc. • Stored in digital media • Accessibility • Through computers • Networks • Internet • Much easier • Production/Reproduction • Conversion from non-digital form • Direct digital production • Duplication • Easy • Inexpensive
Dissemination/Spread of Information • Mechanism • Transfer • Broadcast • Who controls the event and the contents? • Multicast • Who can receive? • How many? • Unicast • Repetition process • Measure • No of people consciously aware as a function of time
Spread of information • Media • Web • Phases • Rise • Decay • Many factors determine the time constants
Spread of Information • Rise Phase • Triggers • Current sensitivities • Mechanisms • Media • Web • Word of Mouth • Decay Phase • Authenticity ? • Other information competing for attention • Time Information Butterfly Effect !!
Controlling Butterfly Effect • Rise Phase • Blocking flow of information • Dictatorships • Decay Phase • Quick challenge to authenticity • Offer competing information to grab attention
Sharing of information • Trust • Handling conflicting information • Creating a consistent view
World Wide Web • Easy Accessibility to HUGE amount of information • Most of the information generated for the Web • Broad Band Access by a large number of people • Web servers backed up by databases of mostly web pages
Live vs. Archived • Live • Collected directly in digital form • As it happens • Text, Audio, Video, Sensor data, … • Archived • Saved as collection of records
Other information • Specific Databases • Law Enforcement • Healthcare • Credit bureaus • Personnel Records • Census Bureau • Financial record • Telephone Records • Hundreds of thousands of such databases exist • Contain a lot of data collected as a part of normal operation of an entity • Business • Government • Private operations • Duplication of a lot of records with little controls
Example – Law Enforcement • Many organizations • Federal • State • Local • Special • Private • Each organization • Collects data and stores it • Controls access to it • Has to conforms to laws, policies and practices • Sharing of information • Exception rather than a norm • Attempts have been made to create “Fusion Centers” • Hardly successful • You Don’t know what you know • You Don’t know what you don’t know
InformationFuture • Assumptions • Unlimited availability of • Processing Power • Storage • Bandwidth Anywhere/Anytime • We are still in the initial transient phase of information revolution Note that Human Capacity to Assimilate has not increased
Impact on Education • Role of a Teacher • What should we be teaching? • What should a student take for granted? • Calculator? • Web Access? • Ability for • Assimilation • Abstraction • Cooperation • Increased Awareness • Changing the world view
Impact on Society • Social Interaction • Cell Phones • SMS • Social Networks • All Aspects are impacted
Impact on Work Environment • White Collar Worker/Information Worker • Not tied to a location • Employer optimizes ROI • National boundaries have little meaning or impact
Impact on Politics • National • We are seeing some of it this year in presidential election • What is a national interest • Internationally • Flow of information is making events known globally • What is the meaning of national boundaries
Resource Constrained World • With limited resources • Information will play an ever increasing role • Decisions will require a higher degree of awareness • Cooperation rather than confrontation
Concluding Remarks • Tip of the Iceberg • Change is occurring faster than the society can adapt to it • Proactive vs. Reactive Participation • So What is information?? • That is a topic for another day
