Abstract:
A forensic verification system (900) extracts a print signature via a print signature extractor (910) from a captured image of a printed halftone. The system (900) utilizes a comparator (920) to compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature. The system (900) utilizes a forensic analyzer (930) to perform a forensic analysis on the signatures based on the comparison to authenticate the printed halftone.
Abstract:
Systems and methods for tracking a slide comprising a tissue sample. In an embodiment, data is received from a Laboratory Information System (LIS) barcode associated with a slide and a proprietary barcode generated by a slide staining system, such as a Ventana slide staining system, to track the slide through the staining process. A new label is printed that contains both the LIS barcode and the proprietary barcode, and is attached to the slide. When the slide is subsequently scanned by a slide scanning system, the slide scanning system reads and decodes the LIS barcode to obtain a LIS barcode value. The LIS barcode value may then be used to retrieve information associated with the slide.
Abstract:
An image forming apparatus (100) to print an image on a recording medium based on print data. The image forming apparatus (100) includes a storing unit (5) to store the print data, an image processing unit to perform image processing on image data included in the print data; a printing operation specification unit to specify implementation of a printing operation; a marking unit to embed marking data in the image data, a marking printing operation specification unit to specify implementation of a marking printing operation, a printing operation implementation unit to implement the printing operation or the marking printing operation, a print data determination unit to determine whether or not the print data includes a setting for the marking printing operation, and a printing operation change unit to change a printing operation performed by the printing operation implementation unit.
Abstract:
Information available at a decoder is embedded into image content after decoding by first representing that information by at least one film grain pattern and then blending that at least one film grain pattern with the decoded image content. Such image content is typically in the form of a movie and examples of the information to be embedded include identification of the specific decoding device, the user of the decoding device, the time and date of decoding, the model number of the device, the versions of software running on the device, the status of the device or connections to the device, the contents of device registers or memory locations within the device, among many other possible data. When an unauthorized copy of image content is discovered, the copied image content undergoes a comparison to the decoded image content to generate difference data. Thereafter, the difference data undergoes comparison with a database of film grain patterns to recover the embedded data.
