Twitter has acquired San Francisco start-up Whisper Systems, a company that makes security software for mobile phones.

Whisper Systems was launched last year by security developers Stuart Anderson and Moxie Marlinspik. They have since launched a range of security and encryption products for Android devices.

"We started Whisper Systems with the goal of improving security and privacy for mobile devices," the company said in a blog post.

"Now that we're joining Twitter, we're looking forward to bringing our technology and our expertise into Twitter's products and services."
