Digital Watermark A digital watermark
A digital signal or pattern imposed on a digital document (text, graphics, multimedia presentations) Visible watermark The more obvious means of discouraging unauthorized use by reducing the commercial value of a document. Invisible watermark The watermark is imperceptible to the human eye When the ownership of data is in question, the watermark will then be extracted to characterize the ownership

傳密入音 利用聲音頻道提供資訊傳播服務 將數位資訊隱藏在音樂中進行傳遞
對一般人而言,只是平常的音樂;但對於接收者來說,可透過筆電或手機的麥克風接收聲音即時解讀其中的數位資訊。
