Escaping the ‘Scrapers’

Scrapers have a major impact on registered sex offenders credit files.
10-12-2010 National:

The Internet has given rise to a dizzying array of people-search sites and data brokers that gather and compile public information and social-networking profiles. The sites gather information from public sources such as property records and telephone listings, and other information is harvested by “scraping” — or copying — websites where people post information about themselves.

The fact that the information is from public records or posted on the Internet generally means that the companies have a right to use it. And many of the firms emphasize that the data will still be available in public records or elsewhere online, even if the information is removed from specific sites. As long as the source of the information remains available, it can simply be scraped again. But determined consumers willing to navigate the maze of companies have some options for requesting that their data be removed from certain sites.

Below, a guide to seeking removal of information from some of the largest sites.

The Privacy Rights Clearinghouse, a non-profit consumer group, keeps a list of online data brokers and scrapers, and whether they allow users to opt out. A few more details can be found in a guide provided to California public officials under a state law that allows them to demand data removal. The Wall Street Journal obtained the guide via a California Public Records Act request. Further information can sometimes be obtained from the companies in question. The Journal contacted several of them separately.

The people-search sites that receive the most visitors, according to comScore Inc., are Intelius Inc., Spokeo Inc. and 123people Internetservices GmbH. ..CLICK for further information on each individual scraper site.. The Wall Street Journal Staff

Early Attention to Privacy in Developing a Key DHS Program Could Reduce Risks

February 2007:

Why GAO did this study:
The government’s interest in using technology to detect terrorism and other threats has led to increased use of data mining. A technique for extracting useful information from large volumes of data, data mining offers potential benefits but also raises privacy concerns when the data include personal information.

GAO was asked to review the development by the Department of Homeland Security (DHS) of a data mining tool known as ADVISE (Analysis, Dissemination, Visualization, Insight, and Semantic Enhancement). Specifically, GAO was asked to determine (1) the tool’s planned capabilities, uses, and associated benefits and (2) whether potential privacy issues could arise from using it to process personal information and how DHS has addressed any such issues. GAO reviewed program documentation and discussed these issues with DHS officials.

What GAO found:

ADVISE is a data mining tool under development intended to help DHS analyze large amounts of information. It is designed to allow an analyst to search for patterns in data—such as relationships among people, organizations, and events—and to produce visual representations of these patterns, referred to as semantic graphs (see fig.). None of the three planned DHS implementations of ADVISE that GAO reviewed are fully operational. (GAO did not review uses of the tool by the DHS Office of Intelligence and Analysis.) The intended benefit of the ADVISE tool is to help detect threatening activities by facilitating the analysis of large amounts of data. DHS is currently in the process of testing the tool’s effectiveness.

Use of the ADVISE tool raises a number of privacy concerns. DHS has added security controls to the tool; however, it has not assessed privacy risks. Privacy risks that could apply to ADVISE include the potential for erroneous association of individuals with crime or terrorism and the misidentification of individuals with similar names. A privacy impact assessment would identify specific privacy risks and help officials determine what controls are needed to mitigate those risks.

ADVISE has not undergone such an assessment because DHS officials believe it is not needed given that the tool itself does not contain personal data. However, the tool’s intended uses include applications involving personal data, and the E-Government Act and related guidance emphasize the need to assess privacy risks early in systems development. Further, if an assessment were conducted and privacy risks identified, a number of controls could be built into the tool to mitigate those risks. For example, controls could be implemented to ensure that personal information is used only for a specified purpose or compatible purposes, and they could provide the capability to distinguish among individuals that have similar names to address the risk of misidentification. Because privacy has not been assessed and mitigating controls have not been implemented, DHS faces the risk that ADVISE-based system implementations containing personal information may require costly and potentially duplicative retrofitting at a later date to add the needed controls. ..more.. by GAO
