- Report 
The data breaches noted here  have been reported because the personal information compromised includes data elements useful to identity thieves, such as Social Security numbers, account numbers, and driver's license numbers. Some breaches that do NOT expose such sensitive information have been included in order to underscore the variety and frequency of data breaches. However, we have not included the number of records involved in such breaches in the total because we want this compilation to reflect breaches that expose individuals to identity theft as well as breaches that qualify for disclosure under state laws. The breaches posted below include only those reported in the United States. They do not include incidents in other countries.
The running total  we maintain at the end of the Chronology represents the approximate number of *records* that have been compromised due to security breaches, not necessarily the number of *individuals* affected. Some individuals may be the victims of more than one breach, which would affect the totals.
In reality, the number given below should be much larger. For many of the breaches listed, the number of records is unknown. Further, this list is not a comprehensive compilation of all breach data (see below).
No, it is not a complete listing of breaches. The list is a useful indication of the types of breaches that occur, the categories of entities that experience breaches, and the size of such breaches. But the list is not a comprehensive listing. Reported incidents affecting more than nine individuals from an identifiable entity are included. Breaches affecting nine or fewer individuals are included if there is a compelling reason to alert consumers. Most of the information is derived from the Open Security Foundation list-serve (see below) which is in turn derived from verifiable media stories, government web sites/pages, or blog posts with information pertinent to the breach in question. If a breached entity has failed to notify its customers or a government agency of a breach, then it is unlikely that the breach will be reported anywhere. If you are aware of a breach that is not included in our list, below, feel free to contact us here: http://www.privacyrights.org/about_us.htm .
Some states have state laws that require breaches to be reported to a centralized data base. These states include Maine, Maryland, New York, New Hampshire, North Carolina, Vermont and Virginia (Virginia’s notification law only applies to electronic breaches affecting more than 1,000 residents). However, a number of other states have some level of notification that has been made publicly available, primarily through Freedom of Information requests. These states include California, Colorado, Florida, Illinois, Massachusetts, Michigan, Nebraska, Hawaii and Wisconsin. For details, see the Open Security Foundation Datalossdb website: http://datalossdb.org/primary_sources 
We usually update this list every two days.
Where do you obtain information about the data breaches that are reported on this Web page?
Most of the breaches summarized below on this page have been obtained from the Open Security Foundation list-serve. As of January 2010, we have expanded our sources to also include Databreaches.net, PHI Privacy and NAID. As of March 2012, we began using the California Attorney General list of data breaches.
- The Open Security Foundation's DataLossDB.org (www.datalossdb.org ) offers a free e-mail list-serve on the latest breaches.
To subscribe to DataLoss, send a message to: email@example.com 
- Consumers may access a list of data breaches from Datalossdb.org upon creating a username and password. The DataLossDB.org page includes a search engine and news articles for the breaches listed below, and also provides an open source database of its data breach records. It is a flat comma-separated value file that can be imported into a database or spreadsheet program for your own data analysis.
- Beginning in January 2010, we have expanded the sources of our breaches. We now include the following sources:
- Databreaches.net (www.databreaches.net ) is a spinoff from www.PogoWasRight.org  and compiles a wide range of breach reports since January 2009.
- Personal Health Information Privacy (www.phiprivacy.net/ ), affiliated with Databreaches.net , is a database that compiles only medical data breaches. Many of these are obtained from the US Department of Health and Human Services' medical data breach list (http://www.hhs.gov/ocr/privacy/hipaa/administrative/breachnotificationrule/postedbreaches.html ), which provides only minimal information.
- National Association for Information Destruction, Inc (www.naidonline.org ) provides monthly newsletters that include a number of data breaches largely due to improper document destruction.
For tips on what to do if your personal information has been exposed due to a security breach, read our guide  at http://www.privacyrights.org/fs/fs17b-SecurityBreach.htm .

Yes. The catalyst for reporting data breaches to the affected individuals has been the California law that requires notice of security breaches. It is the first of its kind in the nation, implemented July 2003.
Forty-six states, the District of Columbia, Guam, Puerto Rico and the Virgin Islands have enacted legislation requiring notification of security breaches involving personal information.
