1 Prof. Kai Hwang, USC, Nov. 22, 2013 Big-Data Analytics and Cloud Security for Trusted Cloud Computing Lec.26 of EE 599, Nov.26, 2013, Prof. Kai Hwang University of Southern California 1 boxshadowdwn Four Research Frontiers : BigData, Clouds, Social Networks, and the Internet of Things boxshadowdwn Shortage of Big-data Analytics, Security and Privacy hinder the acceptance of clouds, social networks and IoT services. boxshadowdwn Crucial R/D Challenges are identified and some new Approaches and Opportunities are revealed in this talk. 2 What is Data Science ? s) Data Science is the extraction of actionable knowledge directly from data through a process of discovery, hypothesis, and analytical hypothesis analysis. A Data Scientist is a practitioner who has sufficient knowledge of the overlapping regimes of expertise in business needs, domain knowledge, analytical skills and programming expertise to manage the end-to-end scientific method process through each stage in the big data lifecycle. Big Data refers to digital data volume, velocity and/or variety whose management requires scalability across coupled horizontal resources 3 Prof. Kai Hwang, USC, Nov. 25, 2013 Practitioners consider themselves Data Scientists Phones, Sensors, Social Networks and IoT are new sources of Big Data square4 Radar, Light Synchrotrons, Smartphones, Bio-imaging, RFID, Sensors, GPS, etc. 3 Hadoop and HDFS dominant Business – main emphasis at NIST – interested in analytics and assume HDFS Academia seem more interested in data management Clouds vs. Grids and Grid of Clouds Modern Big-Data Characteristics: 4 Prof. Kai Hwang, USC, Nov. 25, 2013 4 The Case of Photos (Images)
