A former attorney for Casey Anthony confirmed Thursday that a "video diary" posted to YouTube is that of Anthony but said the video was not "legally obtained."

The Orlando mother found not guilty of killing her 2-year-old daughter, Caylee, talks about her well-being and references being kept in an undisclosed location in the four-minute clip that surfaced on YouTube Thursday. It is not clear where the black-and-white video originated, though multiple reports say it first appeared on a website called caseyanthonyisinnocent.com.

Cheney Mason, one of Anthony's defense attorneys during her trial, said Thursday that the woman in the video is Anthony but said his former client does not know how it landed on the web. 

Mason told Fox affiliate WOFL-TV that "Casey has maintained some notes on her thoughts for personal use, especially for counseling. She did not release this video to YouTube and does not know how they got it. 

"It could not have been legally obtained and was not authorized," Mason told the station.

In the video, Anthony, who is sporting a short, blonde hairstyle and glasses, says she has a new computer and will be posting video diaries. She continuously alludes to being kept in a location, but she never says where she is in the video, which was created Oct. 13. 

"I’m extremely excited," Anthony says. "I’m excited that I’ll be able to Skype and obviously keep a video log, take some pictures and that I have something that I can finally call mine ... It’s been a long time since I’ve been able to call something mine."

"Even if I get off probation early, I'll still be here at least until February -- end of February, seven months, March, my birthday," she says.

Anthony does not mention her 3-year-old daughter, Caylee, whose remains were found in December 2008 in a wooded area not far from the Anthony family home. Instead, she speaks about a dog she's adopted and says "a lot has changed" in her life since the trial.

"I just hope things stay good, and they only get better," she says.
