Twitter looks set to extend its mobile offerings following news that the company is to acquire Whisper Systems, a startup specialising in security products for Android phones.
Twitter has reportedly confirmed that the deal is taking place, although details are available only on the Whisper Systems blog at this time.
Terms of the acquisition remain undisclosed, and Twitter did not immediately respond to requests for further details from V3.
Whisper Systems' software is still in beta and includes WhisperMonitor, Flashback, WhisperCore, RedPhone and TextSecure.
WhisperCore provides device-level encryption for Android phones, and comes with the WhisperMonitor software firewall that filters data and controls its destination.
Flashback integrates with WhisperCore to provide encrypted backup for Android phones, while Redphone is a call encryption service and TextSecure is an encrypted text messaging service.
The latter two were previously offered free to Egyptian activists to help them communicate during the protests.
The company said that the security services will be temporarily suspended while the Twitter acquisition takes place, which has unfortunately coincided with the Egyptian parliamentary election. The software is likely to remain offline during the election's immediate aftermath.
Whisper Systems was founded by computer security researcher Moxie Marlinspike, who is a fellow at the Institute For Disruptive Studies, a research lab dedicated to the development of innovative projects.
"We started Whisper Systems with the goal of improving security and privacy for mobile devices," said the company blog post.
"We were attracted to this not only because we saw it as an opportunity to reinvent the security solutions that never really worked in the PC environment to begin with, but because the stakes are much higher due to the nature of mobile devices, and we didn't like the way things were looking."
Whisper Systems explained that the company is looking forward to joining Twitter's team, and that its offerings will "live on".
"The Whisper Systems software as our users know it will live on (and we have some surprises in store that we're excited about), but there is unfortunately a transition period where we will have to temporarily take our products and services offline," the company said.
