    Abstract: Watermark and pattern detection can be improved by compensating for artefacts introduced into an image by a printer and/or scanner through which the image has passed (24). With the present invention, prior to watermark or pattern detection, the image is filtered or modified to compensate for artefacts introduced by the printer and/or scanner. User is provided with an interface which can be used to change certain parameters such as contrast and intensity (23). The changes made by the user change the compensation (i.e. the tone map) applied to the image. If the user changes the compensation applied to the image it can affect the ability to read the watermark. The present invention provides a system which reverses any compensation introduced by the user so that the watermark or pattern can be more easily read (25). In another embodiment the invention takes into consideration that some printers and scanners have transfer functions which differ in the "x" and "y" directions. Thus the compensation introduced by the filter can differ in the "x" and "y" directions. In one embodiment, a scanner introduces aliasing frequencies into an image. Detection is improved by selectively removing certain frequencies. In another embodiment, the filter compensates for fact that the scanner frequency response falls off at higher frequencies.

    Abstract: A text is inserted as watermark into digital data by using wavelet transform and discrete cosine transform. The method of inserting a text into digital data comprises the steps of: converting said digital data to have a 2-dimensional image format; converting the text to have the 2-dimensional image format; and inserting the converted text into the converted digital data by using DCT and DWT. The text is extracted from the text watermarked digital data by recovering the converted text of the 2-dimensional format using the text watermarked digital data and the original digital data; and extracting the text form the recovered text of the 2-dimensional format.
