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! Each recipient receives his own, uniquely and inaudibly watermarked ("digitally signed") copy of each distributed audio file, ensuring your copyright and enabling you to identify and backtrace any of the delivered copies at any time, instantly and reliably.

Unique watermarks (signatures) are embedded into acoustic content of every file copy delivered to each individual recipient. The watermark contained in each file copy carries information about the file and the recipient of the specific copy. You can easily identify the recipient of a given file copy by extracting the signature contained in any fragment of its acoustic content.

You can choose to declare the hidden signature public; in such case any TA visitor will be able to identify and authenticate the track by analyzing even a short fragment of it and retrieving its copyright information.


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.
