Big Data is a term WPF uses to describe very large datasets and the technologies and practices of handling those datasets. Typically, Big Data datasets are so large that traditional database systems are not able to handle or analyze them.
Sources for Big Data are many and varied. They include web data, sensors, cell towers, census data and other data from the government, social media, transactional data, and a variety of other data collection systems.
We have seen a tendency to use the term Big Data as a loosely defined stand-in for a number of privacy issues that sound the same, but aren’t. For example, Big Data and Data Brokers are sometimes used together. The two ideas are distinct and different, and it is crucial for public policy and discussion that the two are not conflated as being the same thing or even a similar thing. It is possible to work with Big Data and never be a Data Broker.
Large datasets are intriguing to the World Privacy Forum, and our research on large datasets resulting from sensors and ID cards in Asia helped us understand and explore the issue in-depth. Large datasets sometimes present privacy challenges, but sometimes they do not. Much depends on how the dataflows are collected, managed, stored, and so forth. Understanding these differences and knowing when and where the challenges are is going to be important going forward in this rapidly evolving space.
Privacy Act of 1974 — In response to a proposed Department of Homeland Security rulemaking regarding a system of records, the World Privacy Forum filed comments requesting changes. The primary objections are that the proposed system of records commingles records and functions, the proposed exemption is inconsistent with the system notice, and DHS’s proposed exemption from civil remedies was not correct, among other issues. The World Privacy Forum stated in its comments that the Department of Homeland Security should demonstrate its commitment to accountability and transparency in the rulemaking.
Internet privacy — The World Privacy Forum announced today that it would be filing a complaint with the Federal Trade Commission about the posting by AOL of a portion of its users’ search data on the Internet. While the data was not expressly identified by name, the search queries themselves included in some cases personally identifiable information such as individuals’ names, Social Security Numbers, and myriad other personal information. The World Privacy Forum urges consumers to take precautions when using search engines.
Genetic privacy — The collection of DNA material from 500,000 to 1,000,000 or more individuals as part of a large U.S. medical research project raises many challenging ethical, legal, and privacy issues. An advisory committee reporting to the Office of the Secretary of Health and Human Services ( the Secretary’s Advisory Committee on Genetics, Health and Society) has published a detailed analysis of the issues such a project and its associated databases and biobanks would raise in a draft report. The committee’s final report and policy recommendations will be submitted to the Secretary of HHS. The World Privacy Forum has submitted public comments on the draft; the comments include key policy recommendations.
Financial privacy — Joint comments filed by EPIC, Privacy Rights Clearinghouse, and World Privacy Forum.
Domestic surveillance — The World Privacy Forum joined a coalition of 41 civil liberties, privacy, and trans-political organizations in a letter requesting a thorough and comprehensive inquiry by the Committee on the Judiciary into domestic surveillance program(s).
