A method of detecting a digital stamp pattern involves operating a scanning device to create a page image scanned from a document page, inputting the page image into a one-shot trained neural network, the one-shot trained neural network configured to recognize a copy-guard digital stamp pattern using one-shot learning, analyzing the page image using the one-shot trained neural network to detect the copy-guard digital stamp pattern, and on condition the copy-guard digital stamp pattern is detected, issuing an electronic alert.

A digital image processor includes a region proposal network configured to transform digital image inputs into region proposals and bounding box refinement logic configured to transform the region proposals by determining a first set of the region proposals exhibiting dense spacing, determining a second set of the region proposals exhibiting sparse spacing, executing a first transformation to merge at least some of the region proposals exhibiting dense spacing to generate refined region proposals, executing a second transformation to join at least some of the region proposals exhibiting sparse spacing to generate additional ones of the refined region proposals, and applying an expansion transformation to the refined region proposals.

This disclosure relates to a banknote validator. The banknote validator comprises a banknote path formed within an interior of the banknote validator to transport a banknote from an opening of the banknote path through an interior of the banknote validator, a banknote imaging zone defined within a portion of the banknote path, the banknote imaging zone including a reflective region in a first portion of the banknote imaging zone, and a dark region in a second portion of the banknote imaging zone, and an image sensor configured to capture one or more images of at least a portion of the banknote imaging zone.

This disclosure relates to a banknote validator. The banknote validator comprises a banknote path disposed within an interior of the banknote validator, the banknote path including a banknote imaging zone, one or more banknote edge detection surfaces each configured to provide images of edges of a banknote in the banknote path, a banknote imaging sensor configured to provide an image of at least one portion of the banknote imaging zone, and an image sensor configured to capture the images of the edges of the banknote provided by the one or more banknote edge detection surfaces, and capture the image of the at least one portion of the banknote imaging zone provided by the banknote imaging sensor.

An electronic device includes a display, a first camera, a storage unit, and a control unit. The first camera images a face of a user who is operating the electronic device. The storage unit stores an image imaged by the first camera. The control unit includes a processor and, upon execution of a control program by the processor, functions as: a detection section detecting that a suspicious operation is being performed on the electronic device; and a controller allowing, when the detection section detects the suspicious operation, the display to display, as an image to be displayed in occurrence of the suspicious operation, the image that the first camera is imaging.

An image reading apparatus includes a scanner to read a document, a memory to store an address and a job condition of the document read by the scanner, and circuitry to identify a user, send the document read by the scanner to the address under the job condition, determine whether a type of the document read by the scanner is a confidential document, search a number of times the confidential document has been sent to the address in the memory when the type of the document is determined as the confidential document, and display, on a screen, a message whether to send the document read by the scanner to the address under the job condition when the number of the times is less than a predetermined times.

In an approach for determining printability of an electronic file, a computer electronically receives a file for printing. The computer parses the file for one or more of text, images, and formatting indicative of potential copyrighted material. The computer, in response to identifying any text, images, or formatting indicative of potential copyrighted material, identifies potential copyrighted material within the file. The computer determines whether the file may be printed based, at least in part, on the identified potential copyrighted material. In another approach for determining printability of an electronic document, a computer electronically receives a document for printing. The computer locates attributes associated with the document and stored in a separate database, which includes one or more of the following: ownership, licensing information, printability, and number of prints allowed. The computer determines the document is printable based on the attributes and prints the document.

An MFP includes a substrate on which an ultrasonic sensor that outputs a sound wave through vibration is mounted, a horn in a tubular shape configured to limit an output direction of the sound wave output from the ultrasonic sensor, and a buffer member provided between a surface of the substrate on a side on which the ultrasonic sensor is provided and an opening on one side of the horn.
