What the Web knows about you

How much private information is available about you in cyberspace? Social Security numbers are just the beginning.

She had me at hello ... or just about. Our conversation had barely started when privacy activist Betty Ostergren interrupted me to say that she had found my full name, address, Social Security number and a digital image of my signature on the Web.

I had set out to discover just how much information I could find about myself online, and Ostergren, who runs the Virginia Watchdog Web site, was my very first call. If this was what could be uncovered in just a few minutes, what else would I find? Quite a bit, as it turns out.

What information is available about you in cyberspace? Where does it come from? What risks does it present and what, if anything, can you do to protect yourself? To answer those questions I decided to use my own identity, Robert L. Mitchell, a national correspondent at Computerworld, as my research subject.

Starting with the information Ostergren had turned up about me, I spent a few weeks combing through more than two dozen public and private resources on the Web and visiting many other Web sites to build a dossier on myself. I conducted both free and paid searches. I contacted a private investigator for tips on my investigation. And I spoke with data aggregators and privacy experts.

I quickly discovered that while the quantity of publicly available information about individuals to be found online is vast, it is riddled with inaccuracies. For example, I changed my primary residence more than a year ago, but many databases online still have my old address. In other cases, the information is just plain wrong.

Having a common name like Robert Mitchell -- or a famous one like Bill Gates -- makes the job a lot harder. While nuggets of information about you can be pulled up quickly, filtering out all of the data that is not actually about you and sorting out what is accurate is time-consuming. It requires a lot of digging.

But I was starting with a key piece of data -- my Social Security number -- and that makes finding relevant data a bit easier. As I gathered more data, I also reran many searches to get different -- and more targeted -- results. Here's what I found and where I found it.

Information discovered: Full legal name, address, Social Security number, spouse's name and Social Security number, price paid for home, mortgage documents, signature

Much of the publicly available information on individuals online is sourced from online county, state and federal government records databases, and this is where Ostergren found my Social Security number. She hadn't purchased it from a hacker chat room or from shady characters in Russia. She got it by browsing an image of a mortgage document stored in a county database located in a building half a mile from my house.

Over the past five years, bulk scanning and online publishing of such documents have proliferated in many states. In many cases, including New Hampshire -- my state of residence -- little or no attempt has been made to redact sensitive personal data such as Social Security numbers before moving those records online. The public is blissfully unaware that these documents, which were once accessible only in dusty books inside the walls of the registry of deeds, are now freely available over the Web to anyone in the world with a click of a mouse.

Ostergren says that this information is a treasure trove for data aggregators, brokers and criminals. Unlike financial and medical records, which are regulated, Social Security numbers gathered from public records come with no strings attached. They can be republished anywhere with impunity. "You're in a state that is spoon-feeding Social Security numbers to everybody," Ostergren says.

In the county where I live, legal documents from 1975 and on have been scanned and placed for public viewing on the Web. No registration or payment is required to view those records, although there is a charge to print official copies. The database includes thousands of records on New Hampshire citizens, including tax liens, federal liens, divorce papers, financing statements, military discharge papers, death certificates -- even a mobile home warranty. Any legal document filed with the registry is fair game.

In these records I found names, addresses, Social Security numbers, dates of birth, signatures, children's names, educational backgrounds, blood types, work histories and other personal data. Newer mortgage documents no longer contain Social Security numbers (mine was from 2001), but many other documents still do -- including death certificates and tax liens. In my case, fortunately, just one document on file -- the old mortgage -- contained my Social Security number.

Revelations from the rest of my government database searches were less sensational. State and county court documents are public records. In many states, those records are already online and available for public viewing on the Web. New Hampshire's county court records have not been put online, but the state has plans to do so, according to a county official.

Lauren Noether, bureau chief for consumer protection and antitrust at the New Hampshire Department of Justice, says it's just a matter of time before those records are available online. But she is concerned because standards for what information appears in legal documents have changed over time.

"I had an individual call to tell me that their child's name was in [an old] child abuse indictment. Nowadays we don't do that," she says. Noether amended the document, but she worries that bulk scanning and publishing of all historical records would bring many other inappropriate disclosures into public view.

Like many states, New Hampshire has a child sex offender registry. I am not a sex offender, but for the purposes of this story (I am the subject of the investigation, after all) I ran my name through anyway. As expected, I wasn't on the list, but it was chilling to find three other Mitchells listed there.

My next stop was the federal Public Access to Court Electronic Records (PACER) database, which contains U.S. District, Appellate and Bankruptcy court records. Here the government wants to know who is searching. The registration process for users involves entering your Social Security number, date of birth and other data.

I found myself trolling through dozens of records of people who were not me, at a cost of $.08 per page of results. I pulled up a total of 119 records, including 51 Robert L. Mitchell bankruptcies.

Another Robert L. Mitchell had been arrested for kidnapping. But nothing matched the Robert L. Mitchell I was researching.

The PACER system required that I conduct a separate search for each jurisdiction. CriminalSearches.com is a commercial site that aggregates the same information so that you can do a single search across all jurisdictions -- and it's free. I executed a free search on the Web site. Apparently, I have a clean record in all 50 states.

I also searched state and county databases for the state in which I reside. Database aggregators such as LexisNexis pull information from all of the various local, state and federal databases and roll them up for easier searching, but you need to buy a subscription to use such services.

Computerworld has a LexisNexis subscription, but that costs money. While I did fork over $.08 a page for PACER results, that amounted to less than a dollar. At this point in my investigation, I wanted to see how much I could find for nothing -- or next to nothing -- before resorting to fee-based services.

Source: Free people searches

Information discovered: Employer name, job title, age, month and date of birth, phone numbers, wife's name and age, historical addresses and phone numbers, personal e-mail address, identifying photographs, employment history

I continued my investigation with the people and business search Web sites, including ZabaSearch, WhitePages.com, PeopleFinders.com, US Search, Intelius, Switchboard and PublicInfoGuide.com. The initial searches were free, although each service charged a premium for some of the data it uncovered. As I found out, you get what you pay for.

I gathered plenty of data on Robert L. Mitchells, but most of the data wasn't relevant to the Robert L. Mitchell I was investigating. Each search yielded multiple results, including some records with outdated information about me and others with totally inaccurate data. In some cases, aggregated data clearly had been mismatched, which appeared to be the result of mashing together two different Robert Mitchells into one identity.

ZabaSearch pulled up only an e-mail address I don't use and another that no longer exists, but it did find my mailing address, which it displayed on a satellite map. WhitePages.com had my name and phone number associated with a wrong address. Switchboard incorrectly described my home telephone number as unlisted. PublicInfoGuide.com found a residential address but listed four "relatives" that I never knew I had. PeopleFinders returned an address and phone number in another state where I had lived 20 years ago.

In some cases, part of the search results, such as the full address or e-mail address, was deliberately omitted. PeopleFinders located a Robert L. Mitchell in the correct town but wanted $1.95 for the full address. As up charges go, that was cheap: US Search wanted $10 to divulge the full address. I found it unnecessary to pay for these results, since different sites tended to provide different information upfront -- I could piece together all the bits of free information from various sites.

My Computerworld affiliation didn't turn up initially, nor did my business phone lines or my cell phone number. A search at ZoomInfo produced my correct title and Computerworld affiliation, but the work history was a comedy of errors, including incorrect titles and a stint as a PC World contributor that I must have forgotten. Under "Education," the results simply said "MSN dial-up."
