Technology makes it easier to connect with the people in your life, but it can also enable others to connect to you without your knowledge.

People can learn all about your private life through your cell phone, and one woman said she was stalked for three years because of it. Susan, who asked that her real name be kept private because of worry over her safety, said her ex-boyfriend tormented her using only her cell phone to do it.

"He knew where I was all the time," Susan said. "If I was at dinner somewhere. He would text me and ask me how dinner was. I had no idea how he knew where I was."

Most people know that the GPS in a cell phone can track your every move, but that's just the beginning. Widely available software that can be installed on almost any cell phone can track not just your whereabouts but also your private conversations and personal information.

"I thought I was going crazy," Susan said. "It's just unnerving knowing that somebody 24/7 knows where you're at, what you're talking about, what's going on, everything about you."
