An electronic device and a method for processing an image by the electronic device according to various embodiments of the present invention are provided. The method may comprise: generating password information for a first image using security information of a user; changing the first image to a second image using the generated password information; and transmitting the second image and the password information in response to a transmission request of the first image. Various other embodiments may be available.

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.

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells in decipherable. The invention also provide method and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cell for secured viewing on a user browser or computer.

A printed material processing device includes: a feature information extracting unit configured to compare read printed-material image information obtained by reading a printed material, and extract a portion equivalent to a difference between the two sets of information as feature information; an image generating unit configured to generate an image of a mark to be additionally printed near a location of the feature information, set first information indicating a positional relationship between the mark and the feature information, set second information indicating a method of extracting the feature information and a feature quantity to be extracted from the feature information, and generate an image of code information to be additionally printed in a position on the printed material, the code information including the first information and the second information; and an image forming unit configured to additionally print the mark and the code information.

An image forming apparatus, guide providing method thereof, cloud server and error analyzing method thereof are provided. The image forming apparatus may include a scanner configured to scan a script and generate a scan image, a communicator configured to communicate with a cloud server, a display configured display a screen, and a processor configured to control the communicator to transmit the generated scan image to a cloud server, and in response to receiving an error solution guide of the scan image from the cloud server, control the display to display the received error solution guide.

An electronic apparatus which prevents and/or reduces photographing of contents is provided. The electronic apparatus includes a camera and a processor configured to cause the electronic apparatus to turn off the display and/or control a display to display a UI for restricting photographing of the content in response to a predetermined object being detected in an image received by the camera.

A system for previewing protected media comprising a touchscreen display, a processor, and a memory having executable instructions stored thereon that when executed by the processor cause the processor to receive an original image from a server over a network, generate a blurred copy of the original image, overlay the blurred image over the original image, detect user interaction on the touchscreen display, determine location of the user interaction, and apply a mask on a section of the blurred copy of the original image corresponding to the determined location of the user interaction.

When a first image is designated in an image output instruction, a first determination portion in an image processing apparatus determines whether or not an operator is a restricted subject who is restricted from outputting through an output portion, on the basis of restriction information. A restriction process portion executes a restriction process of restricting output of first image data of the first image through the output portion when the operator is determined to be the restricted subject by the first determination portion, and approves output of the first image data of the first image through the output portion when the operator is determined not to be the restricted subject by the first determination portion.

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells indecipherable. The invention also provides methods and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cells for secured viewing on a user browser or computer.

An image reading apparatus and a control method thereof are provided. The image reading apparatus includes a communication device configured to perform communication in a preset communication manner, a scanner configured to generate a scan image by scanning a manuscript, and at least one processor configured to control the communication device to transmit use information of the manuscript to an address corresponding to authorship information in response to a preset security pattern including the authorship information being detected in the generated scan image.
