    摘要: A system creates a copy of a document by: receiving an electronic representation a document to be copied onto a substrate; identifying a non-invasive watermark to be printed on the substrate; analyzing the document and the non-invasive watermark to determine whether a threshold amount of the non-invasive watermark can be printed in a white space of the document; and creating a secure copy of the document with the watermark. If the threshold amount of the non-invasive watermark can be printed in the white space, the system will print at least a portion the non-invasive watermark in the white space. Otherwise, the system will modify at least a portion of the non-invasive watermark to comprise an invasive watermark portion, and it will print the invasive watermark portion over a portion of the document's content.

    摘要: The invention relates to a security element applied onto printing substrates (bank notes, securities, product packagings, identity cards/labels or other similar documents) by printing, comprising a unique identifier as primary information visible to the naked eye and secondary information protecting against copying non-visible to the naked eye. The unique identifier is typically a point code. Said secondary information is represented by a structure with the largest dimension of 2 to 40 microns, and due to printing distortions arising when the security element is applied onto a printing substrate, said secondary information is non-reconstructable from the print of the security element and a statistically analyzable inherent feature is associated to it. The invention also relates to a printed matter with such an inventive security element and to a method to check authenticity of a printed matter with the inventive security element in visible light (380-750 nm).

    摘要: A method of scanning a set of documents in a container such as a file folder or storage box where the container contains a unique label containing identification associated with the documents in the container. The label comprises both alphanumeric characters and color information where each character is associated with a particular color. By scanning the container and analyzing the image of the container the unique identification can be retrieved with increased reliability by using both the color and alphanumeric information.

    摘要: Some implementations may include a computer-implemented method for applying at least two digital watermarks to a digital document, the method including: receiving a digital document comprising visual contents; generating a first digital watermark to be visually presented at a first time point; generating a second digital watermark to be visually presented at a second time point, the second digital watermark being different from the first digital watermark and the second time point being different from the first time point; and applying both the first digital watermark and second digital watermark to the digital document t.
