A watermarking method converts a watermark message into a Frequency Shift Keying (FSK) signal and embeds the FSK signal in a host signal. The spectral properties of the FSK watermark signal facilitate its detection, even in applications where the watermarked signal is corrupted. Because of these pro
A watermarking method converts a watermark message into a Frequency Shift Keying (FSK) signal and embeds the FSK signal in a host signal. The spectral properties of the FSK watermark signal facilitate its detection, even in applications where the watermarked signal is corrupted. Because of these properties, the FSK watermark signal can perform the dual function of identifying the watermark's presence and orientation in potentially corrupted media, and also conveying a hidden message in the host signal. Such a watermark may be referred to as a self-orienting watermark.

The method of claim 1, further comprising, receiving a summary command; and presenting the portions of data that correspond with at least one freeform digital ink annotation along with at least one freeform digital ink annotation. 7. The method of claim 1, the data being at least one of medical, engineering, experimental, scientific, financial and business data. 8. A method for annotating a data trace with freeform digital ink, the method comprising: displaying a data trace representing data on a display; receiving at least one freeform digital ink annotation on the data trace; displaying the freeform digital ink annotation on the display of the data trace; selecting at least one of the at least one freeform digital ink annotation; identifying, for each selected freeform digital ink annotation, at least one portion of the data of the data trace associated with that selected freeform digital ink annotation; and managing a storage of the at least one portion of the data associated with the at least one selected freeform digital ink annotation; wherein the data trace is at least one of a barogram, an electrocardiogram, a kymogram, a polygram, a seismogram and a thermogram; wherein managing the storage of the at least one portion of the data comprises saving the identified at least one portion of the data and deleting remaining portions of the data. 9. The method of claim 1, the data trace being an audio trace. 10. A method for annotating a data trace with freeform digital ink, the method comprising: displaying a data trace representing data on a display, the data trace being a series of images from a video data stream; receiving at least one freeform digital ink annotation on the data trace; displaying the freeform digital ink annotation on the display of the data trace; selecting at least one of the at least one freeform digital ink annotation; identifying, for each selected freeform digital ink annotation, at least one portion of the data of the data trace associated with that selected freeform digital ink annotation; and managing a storage of the at least one portion of the data associated with the at least one selected freeform digital ink annotation; wherein managing the storage of the at least one portion of the data comprises saving the identified at least one portion of the data and deleting remaining portions of the data. 11. A system for annotating a data trace with freeform digital ink, the system comprising: a display of a data trace, the data trace being a graphical representation of a time-varying signal; an input device for receiving at least one freeform digital ink annotation of the data trace, the display being responsive to the receipt of at least one freeform digital ink annotation to render the at least one freeform digital ink annotation on at least one corresponding portion of the data trace; and a processor that is responsive to a selection of at least one of the at least one freeform digital ink annotation to identify, for each selected freeform digital ink annotation, at least one portion of the data of the data trace associated with that selected freeform digital ink annotation and to manage a storage of the at least one portion of the data associated with the at least one selected freeform digital ink annotation; wherein managing the storage of the at least one portion of the data comprises saving the identified at least one portion of the data and deleting remaining portions of the data. 12. The system of claim 11, further comprising a processor for mapping the at least one freeform digital ink annotation to a corresponding portion of the
