Are you careful enough?
Criddle described a family tree her own father posted online to display the fruits of his genealogical research. He took it down once she pointed out that "mother's maiden name" is a common security backup question for online accounts. That kind of personal information can give criminals access to financial accounts, help them select and profile potential victims, and even put users' friends and relatives at risk, Criddle said.
I have long been concerned about the level of personal information available on the web, and not in genealogy only, but also through social networking and the latest trend, family and personal blogs. Trying to stop it would be like the child with his finger in the dyke trying to hold back the flood. The only real prevention rests with individuals rethinking what they put online and at what level of security.
