Send Secret Messages With StegDroid Alpha

There are some interesting Android apps out there, and XDA forum member fredley‘s app is no exception.

The XDA member is working on Stegdroid Alpha, an app for his final year dissertation. The app performs Echo Steganography on wave files and uses this to encode short text messages in an audio file, then share it.

Essentially, Stegdroid records a file form the microphone and embeds a secret message into it. The file can then be sent to someone else, and if the receiving party also has the same application, they can extract the secret message from the audio file. The dev states that anyone listening to the audio file wouldn’t be able to tell that it’s got a message hidden in it, as the difference is hard to distinguish with the human ear.

The dev is also looking for some constructive feedback from testers, so for the QR code to download the app, head on over to the application thread.

While we don't have many details about the sources of this leak, it has apparently been confirmed true by a poster at hardare.fr that gave some more details on model names for each version of the upcoming LG flagship. However, these leaks don't point towards all G4...
