Description
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.

Does what it says. Good app, simple. Could expand app for steg. Encrypted image in image embedding, as attachment.

Doesn't work on my X10. Crashes after audio is recorded.

This is simple to use and works brilliantly. Newly added menu items for Help & Decode make something simple to use even easier.

Veri nice app The app is consistent and do exactly what is promised. It you have problem loading the file back is because you need to choose stegdroid and the open app for the file instead of the music player.
