Your Facebook Photo Says More Than You Think, Research Says

A photo is worth a thousand words, as the saying goes, but your Facebook photo might be worth more. It is, after all, available to the entire world. Let's face it; we're all vain to varying degrees, and have some sort of self-image that we're constantly trying to project online. A newly released study aims to determine just what it means to project our avatar through the lens of social networking sites.

Researchers from Sonoma State University recently found that images can pretty reliably convey some, though not all, personality traits. In the study, 12 random people looked at photos of 123 undergraduate students in different poses -- both
"neutral" and "spontaneous." (The "neutral" poses were dictated by researchers, while the "spontaneous" poses were self-directed.) The subjects were then asked to rank the photos according to 10 traits: extroversion, agreeableness, conscientiousness, emotional stability, openness, likability, self-esteem, loneliness, religiosity, and political orientation. In order to judge the accuracy of the subjects' appraisals, scientists compared them to the self-evaluations submitted by the photographed students.

Your Old Hard Drive Is a Criminal's Gold Mine

Second-Hand Hard Drives a Gold Mine for Thieves

Whether we're throwing away an old computer, selling it to a friend or just replacing its aging hard drive, many of us are improperly erasing our sensitive personal data, if we're even bothering to erase it at all! These are the findings of a study performed by a multi-national coalition of research teams from U.K. teleco BT, the University of Glamorgan in Wales, the University in Perth in Australia, and Virginia's Longwood University here in the U.S. The researchers examined 350 hard drives received second-hand and found that more than a third of the disks had not been properly cleared of preexisting data.

The hard drives contained surprising mix of personal and corporate information such as bank and credit-card information, salary details, medical records and corporate financial data. The disks were purchased in a variety of places, both from online and brick-and-mortar retailers as well as at computer fairs and shows.

The ease of obtaining this information makes it a treasure trove for potential identity thieves. Users and businesses tend not to realize that deleting or simply formatting a hard disk doesn't actually remove all the data from the drive and that a dedicated hard drive cleaning application is needed.

Deleting or reformatting simply removes information about the location of files, meaning they're ready for overwriting, but until new data is written in the same physical location on the drive, the data is recoverable with freely-available utilities. Thankfully, there are also freely-available disk-cleaning apps that write over every area of the disk several times with random garbage data. Here are just a few:
