摘要： A forensic authentication system includes an imaging device to capture an image of a printed mark and a non-printed area of a substrate directly adjacent to the printed mark, and a processor to run computer readable instructions. The processor can run computer readable instructions to utilize a model to define a substrate region that corresponds with at least a portion of the non-printed area of the substrate directly adjacent to the printed mark; and computer readable instructions to generate a substrate signature for the defined substrate region. Each of the computer readable instructions is embedded on a non-transitory, tangible computer readable medium.

摘要： An image is obtained of an identifying object that is on a printed document. A forensic signature is extracted from the image. Access to the extracted forensic signature profile is enabled via information encoded in the identifying object. The identifying object may be interpreted to access the forensic signature for comparison with another.

摘要： A method for model-based signature profile extraction includes capturing an image of an authentic glyph. An outline model is fit to the image of the authentic glyph, and an authentic signature profile is extracted based on the outline model. A signature profile extracted from an image of another glyph may be compared to the to the authentic signature profile so as to forensically verify authenticity of the other glyph The system for model-based signature profile extraction includes a controller, a capture unit, an outline unit, a profiling unit, and a forensic verification unit. A computer readable medium containing executable instructions is also described.

摘要： Document copying systems and methods include initiating a copy job (20) for copying a document (1) having document content. A log (22) of the copy job is generated, and the document is scanned to create a document content image (24). The log is encoded using an input image to produce a data-bearing halftone image (26) which is merged with the document content image (28). The merged data-bearing halftone image and the document content image are printed (30) to produce a copy (2) of the document.

摘要： A forensic verification system (700) extracts a print signature via print signature extractor 710 from the boundary of a halftone contained in an image. The system (700) compares the print signature to a reference signature stored in a registry via comparator 720 to determine differences between the print signature and the reference signature. The system 700 performs a forensic-level statistical image analysis via forensic analyzer 730 on the print signature and the reference signature based on the comparison to authenticate the printed media.

摘要： 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.

摘要： An embodiment provides a method for compression of a real-time surveillance signal. This method includes receiving a signal from a monitoring device and analyzing the signal to be monitored to compute spectral content of the signal. This method also includes computing the information content of the signal and determining a count of a number of coefficients to be used to monitor the signal. This method includes deploying a strategy for computing a plurality of coefficients based on the spectral content of the signal and the count of the number of coefficients to be used for monitoring the signal. This method further includes monitoring the signal and resetting the system in the case of above-threshold changes in a selected portion of the plurality of coefficients.
