A pseudo-random steganographic camouflage includes a graphic design printed or painted as camouflage on an outer side of a substrate like Mylar thermal blanket sheets, uniforms, and adhesive tapes. The graphic design is uniquely generated from pseudo-random noise in four overlaying colors that each begin as a raster of randomly generated noise CDMA encoded with a PRN and a message in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed in groups together with a monochrome mixing mask to produce a whole tile of concealment camouflage that will conjoin seamlessly within arrays of such tiles. A further refinement visually adds a distorted-grid mesh-texture to the pseudo-random steganographic camouflage, and even faint watermarks of commercial trademarks.

An image decoloring apparatus includes a reader configured to read an image on a sheet to acquire image data, a storage section configured to store the image data acquired by the reader, and a first heater configured to heat the sheet. The apparatus further includes a difference extractor configured to extract difference image data based on first image data read from the sheet before it is heated by the first heater and second image data read from the sheet after it is heated by the first heater. The apparatus additionally includes a setting section configured to set a password required to access the difference image data.

An electronic device includes an imager and one or more processors operable with the imager. The imager captures at least one image of a plurality of persons. The one or more processors blur depictions of one or more persons of the plurality of persons until a reveal permission instruction is detected.

A concealment substrate manufacturing process begins by printing or painting a graphic design as camouflage on substrates like mesh-textured uniforms, military equipment, Mylar thermal blanket sheets, adhesive tapes, etc. The graphic design is uniquely generated from pseudo-random noise in four overlaying color pigments that each begin as a raster of randomly generated noise in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed together in groups with a monochrome mixing mask to produce a whole tile. Such concealment camouflage tile conjoins seamlessly on-edge within other arrays of identical tiles. One variation adds a distorted-grid mesh-texture overly texture to the concealment camouflage, and even a faint watermark related to a commercial trademark.

While jobs with confidentiality are in principle kept from showing on a job list, display of the jobs with confidentiality is enabled with a simple operation. In an image forming apparatus, a display control section allows a display section to display a job list showing a plurality of executed jobs, wherein among the jobs, one job containing a predetermined word or character string representing confidentiality is excluded from the job list. When a predetermined keyword is input through a touch panel, the display control section allows the display section to display a confidential job containing the keyword.

Disclosed are various examples of providing analog security for digital data. A first framelet is decrypted. The first framelet includes a first set of subpixels for each pixel of content requested from a network service. A second framelet is also decrypted. The second framelet includes a second set of subpixels for the respective pixel of the content. The first framelet and the second framelet are rendered separately. The first framelet is visually aligned with the second framelet to reproduce the content. A shade of each pixel is reproduced based on the first plurality of subpixels being visually aligned with the second plurality of subpixels.

A visual privacy system unilaterally blocks rolling shutter cameras by providing a periodically interrupted ambient light source imposing bright and dark bands on the image yet at a frequency imperceptible to human observers in the environment. Communication of the modulation pattern to authorized cameras allows unaffected imaging in these regions by authorized individuals. The system also contemplates operation in a barcoding mode with a light modulation providing embedded barcodes that can be extracted from images taken in the region to indicate that the images were improperly acquired and to block the images in certain applications.

Provided herein are methods and systems for multi-person authentication and validation systems for sharing of images. The multi-person authentication and validation system may identify the respective representations of one or more individuals captured in an image, and request authorization for sharing the image from the one or more individuals captured in the image. In some instances, the multi-person authentication and validation system may provide a different image version for sharing if at least one of the one or more individuals denies authorization.

A method for collecting data related to dialog including receiving one or more user input conditions of a first user for a chat room including the first user and one or more second users associated with the first user, collecting data related to dialog from the chat room according to the user input conditions to generate a simplified dialog, and generating media data according to the simplified dialog may be provided. Further, a non-transitory computer-readable storage medium storing instructions for implementing the method, a computer device configured to perform the method, and a server system configured to perform the method may be provided.

A method of providing information for display, from a portable electronic device, includes displaying information on a display of the portable electronic device, identifying a portion for redacting from the information displayed on the display of the portable electronic device, extracting the portion from the information to provide redacted information and an extracted portion, storing the redacted information, protecting and storing the extracted portion in association with a location identification in a file, and sending the redacted information and sending the file including extracted portions associated with the location identifiers.
