StegDroid Alpha

StegDroid Alpha


This app is being developed as part of my Part II Project in Computer Science at the University of Cambridge.

This app records audio, and embeds a secret text message into the audio file. You can then share the recording with others, who can extract the secret message with the same app. The messages can be encrypted with a password for extra security.

The app uses a process called Echo Steganography to embed the secret messages. The difference between an unencoded and encoded audio file is inaudible to the human ear, only complex steganalysis can determine whether the file has any data hidden in it. This method of data hiding is also resistant to transcoding between audio formats.

Recent changes:
* Multicasting of messages to contact groups added

* Fixed bug with sharing files in paranoid mode
* Better memory management, should work more reliably with longer messages
* Reduced error rate (less garbled messages)
* Reduced file size by 33%
* Other bug fixes

Why read call logs? The phone numbers of people I call r on there. I haven't their permission to spy on them. Fix the privacy and then give me a holla shug.
