Document Summary
Made possible by modern computing and communication technology. World wide web - is a universal library, all new public information is put here. Commerce - information is now a major commodity, information systems are a major tool of commerce. A lot of property is now digital, (e. g books, music, videos) Digital property can be reproduced almost instantaneously at extremely low cost. Who owns the metadata about intellectual and digital property? (e. g data about you, information related to things you post) Privacy (e. g identity theft), encryption may enable some privacy to be preserved (e. g encrypting hard drive) Risks - the economy depends on computer networks and software, and these systems are tied together e. g faulty healthcare software. National borders are no longer a major obstacle. Crime can be carried out from a distance. Warfare may now include attacks on information systems ( spreading false information, etc) Small countries and groups can attack large countries through this method.
