Information privacy & Big Data

摘要

Big Data is arguably one of the killer apps to emerge over the past decade. The technology originated from a technique developed by Google called MapReduce, which uses parallel processing to generate analytics from massive amounts of data. An open source version of MapReduce, called Hadoop, has effectively "democratized" the availability of Big Data. With this easy-to-use platform, enterprises are finding new ways to solve problems and extract value from data. However, Big Data analytics often involve access to data that should be protected, such as medical records, tax information and personally identifiable information (PII). Security and compliance professionals need to ensure Big Data deployments do not violate access control policies with respect to this information.
