The present invention relies on the moiré patterns generated when superposing a base layer made of base band patterns and a revealing line grating (revealing layer). The produced moiré patterns comprise an enlargement and a transformation of the individual patterns located within the base bands. Base bands and revealing line gratings may be rectilinear or curvilinear. When translating or rotating the revealing line grating on top of the base layer, the produced moiré patterns evolve smoothly, i.e. they may be smoothly shifted, sheared, and possibly be subject to further transformations. Base band patterns may incorporate any combination of shapes, intensities and colors, such as letter, digits, text, symbols, ornaments, logos, country emblems, etc. . . . . They therefore offer great possibilities for creating security documents and valuable articles taking advantage of the higher imaging capabilities of original imaging and printing systems, compared with the possibilities of the reproduction systems available to potential counterfeiters. Since the revealing line grating reflects a relatively high percentage of the incident light, the moiré patterns are easily apparent in reflective mode and under normal illumination conditions. They may be used for the authentication of any kinds of documents (banknotes, identity documents, checks, diploma, travel documents, tickets) and valuable articles (optical disks, CDs, DVDs, CD-ROMs, packages for medical drugs, bottles, articles with affixed labels).

The manufacturing process for a data carrying disc, such as a CD, begins with the production of a master, and in the physical manufacturing process of the master, variations are introduced which give the master distinctive physical characteristics and cause errors in the data. The master is used to form generations of discs, and the physical characteristics of the master are passed on down the generations. A group of discs manufactured from the same source consistently exhibit the physical characteristics of the master, and those physical characteristics are used as a "fingerprint" for identifying that source. To determine the provenance of a data carrying disc, uncorrected data is read from the disc. Information about errors is extracted from the data read. The error information is then compared with characteristic error information which characterises data carrying discs produced from a well known source to determine whether the data carrying disc has been produced from the known source. The error information extracted is representative of errors arising from the physical manufacturing process.

An apparatus and method for re-surfacing compact discs. One method is a two-step method in which the disc to be re-surfaced is first placed on a shaft. A resilient pad supports an abrasive medium and is positioned so the abrasive medium overlaps only the protective layer of the CD. The disc and abrasive material are rotated in opposite directions at about the same speed to remove deeper blemishes in a wet operation. Subsequent polishing is accomplished in a similar manner using a polishing compound instead of an abrasive. The re-surfacing and polishing apparatus each have motor driven shafts which are parallel and spaced apart and support the CD and pad in a cabinet. A transparent cover extends across the top of the cabinet. In another embodiment, the resurfacing and polishing is accomplished in a one-step operation in which polishing fluid is applied to a non-abrasive medium is utilized and the fluid is continuously recycled.
