Giovanni's Digital Watermarking Approach Architectural Advantages
Encoder and the related key	Blue Spike's watermarks are embedded using a Giovanni encoder and a separate, uniquely identified cryptographic key, putting all security outside each embedded copy. The key includes critical information, not only describing the message in the watermark but also providing a map of the location of each embedded message.
Random Location	By means of Blue Spike's uniquely created key, the watermark can be embedded and repeated in random locations throughout the entire signal, making it harder for potential pirates to detect.
Decoder and the related Key	When decoding Blue Spike’s watermarked content, the user must have the Giovanni decoder and the original uniquely identified cryptographic key. Without the related key, which is held only by the content owner, the embedded watermark cannot be read or falsified.
No False Positives	Only authentic information will be decoded from a signal with a Giovanni decoder and the related key. If the original watermarked information is altered or removed, the related key and decoder will indicate that a breach has occurred.
Embedding Process	Blue Spike's Watermarks are embedded using a psycho-acoustic model, which identifies both perceptually significant and insignificant parts of the signal, making Blue Spike’s watermarks imperceptible, difficult to alter or remove, and robust.
