What is it?

TrustedAudio (TA) is a professional web-based tool that provides an easy and reliable way to share, deliver, and distribute audio files securely by means of watermarking and digital signing.

Simply log in, upload your audio files, fill in the recipients' info, and send the files! All recipients receive their own uniquely and inaudibly watermarked (“digitally signed") copy of each distributed audio file.

Unique watermarks are embedded into every audio file copy delivered to each individual recipient. Records of each watermark, together with the file and the recipient info associated with it, are securely stored in the TA database, enabling the file owner to identify and backtrace delivered copies at any time, instantly and reliably.


Who is it for?

For musicians, recording studios
and music labels

Send watermarked music promos and releases to your desired recipients without fear of piracy; you can backtrace the pirate and easily identify the leak source by retrieving the hidden digital signature with the recipient's info from any fragment of your watermarked music.
Claim your authorship by watermarking your track with a publicly retrievable digital signature before sharing it with the world; anyone interested will be able to authenticate your track by retrieving its signature directly on the TA front page.
Got your own web store? Easily integrate it with TA, and start selling watermarked tracks to prevent piracy.
