"Do I worry about Willow and Jaden? No, they were born into that world. They're on the internet all the time, so they know the game. They know where to go, what to say. They're far more savvy," a website quoted Smith as saying.
The actor has two kids - Jaden, 13, and Willow, 11, - with wife Jada Pinkett Smith.
Smith feels his well-guarded kids might suffer with things that will hurt their self-esteem in the future.
"Of course, there are going to be things that are hurtful and self-esteem issues, like we all have, but I grew up in a neighbourhood, where I saw a guy get shot and take nine bullets to the chest, so Hollywood is a far safer experience than where I grew up," he said.
The 43-year-old has been spending more time at home recently as he has been working in the production department rather than in front of the camera. He admits his family is ready to see him back at work.
"Willow's doing her music and whipping her hair, Jaden's got a TV show. And daddy's been sort of producing at home. But everyone's really ready for daddy to go back to work now," he said.
