A document authentication method determines the authenticity of a target hardcopy document, which purports to be a true copy of an original hardcopy document. The method compares a binarized image of the target document with a binarized image of the original document which has been stored in a storage device. The image of the original document is generated by binarizing a scanned grayscale image of the original document. Halftone and non-halftone text areas in the grayscale image area separated, and the two types of text are separately binarized. The non-halftone text areas are then down-sampled. During authenticating, a scanned grayscale image of the target document is binarized by separating halftone and non-halftone text areas and binarizing them separately, and then down-sampling the non-halftone text areas. The binarized images of the target document and the original document are compared to determine the authenticity of the target document.

Method for producing a label having at least one identifier and at least one authenticator printed on a printable medium. A unique identifier is generated by a centralized system or a printing device, and the unique identifier is printed on the printable medium incorporating the authenticator. The unique identifier is generated without relation to a product. The method is implemented with a system including one or more printing devices, one or more recording devices and one or more activation devices communicating with the centralized system.

Example embodiments relate to partial snapshots for creating generalized snapshots. An example method may include, in response to an event, accessing a user interface screen or view associated with an application. The screen or view includes multiple pixels arranged over an area. The method may include sampling the multiple pixels by capturing a portion of the total pixels included in the screen or view. The sampling may include maintaining a dispersion of the captured pixels over the area of the screen or view and preventing clustering of captured pixels within sub-areas of the area. The method may include transmitting the captured portion as a partial snapshot to a system to create a generalized snapshot from the partial snapshot and other partial snapshots.

An image processing apparatus is communicable with a system including a censorship function, and includes one or more controllers having one or more processors and one or more memories, and the one or more controllers are configured to transmit an image acquired by reading a display medium to the system, receive a censorship result from the system, and control the image processing apparatus to perform a predetermined operation corresponding to the received censorship result, wherein the predetermined operation is a preset operation to be performed by the image processing apparatus based on the received censorship result.

An information processing apparatus includes a processor, in which the processor causes a display, in a case where a shared access right is set to data to be processed, the data being stored in an external apparatus, to display information indicating that the data is stored in the external apparatus, before a user logs in to an apparatus that processes the data, and the processor causes the display, in a case where the shared access right is not set to the data and an access right of a specific user is set to the data, not to display the information before login, but display the information after the specific user logs in to the apparatus.

An information processing apparatus includes circuitry. The circuitry transmits document data in response to a request signal transmitted from an information processing terminal and requesting output of the document data. Based on an information signal transmitted from the information processing terminal and indicating information that is not described in a document indicated by the document data, the circuitry generates latent-image data as a latent image including the information signal and the document data. The circuitry outputs the latent-image data and the document data.

An information processing apparatus includes a processor configured to, in a case where an instruction to change a name associated with an operator that is associated with a process of transmitting target data to a transmission destination of destination information set in advance and is shared among plural users is received, set a display setting of the destination information associated with the operator to non-display of not displaying the destination information.

An example image forming apparatus includes a feed unit, an in-line scanner, and a processor. The feed unit is to feed, to the in-line scanner, a print medium on which an image is formed, the in-line scanner is to scan the fed print medium to generate a scan image, and, in response to the scan image fulfilling a condition, the processor is to control the image forming apparatus to perform an action corresponding to the condition.

Self-verifying hidden digital media using a novel interactive component that reveals a secondary hidden watermark. One method reveals at least one hidden image into a visible image, may include the steps of generating, via a processor, a first image that is visible on a computing device screen; generating, via a processor, at least one second image, the at least one second image being in an invisible or nearly invisible state to the human eye in a neutral state and visible in a user activated state. In one embodiment, the activated state of the computing device is achieved when the computing device screen is zoomed in or out, pointer scrolled in a predetermined way, or when the first image has its window size changed.
