A system for preventing private image data captured at an endpoint from being shared during a videoconference is provided. A user can select three-dimensional regions which will not be seen during a videoconference while areas in front of the designated regions remain viewable.

An information processing apparatus includes a processor configured to: receive a request to view a document, from a viewing user who views the document; obtain a document file having document information and specification information, the document information describing content of the document, the specification information including multiple figures disposed on the document, the figures having multiple format types, the figures being used to specify areas in the document; obtain user information describing the viewing user; and, in display of the document to the viewing user, determine hidden areas on the basis of a format type associated with the user information in advance, the hidden areas being in the document and being areas in which the content of the document is not displayed.

A first set of concealment attributes is received from a first user. The first set of user concealment attributes are associated with a document. A first set of document concealment attributes is received from the user. The first set of document concealment attributes are associated with the document. The document, based on the first set of concealment attributes and the first set of document concealment attributes, is stored.

There are provided systems and methods for a locally broadcasted token to cause image masking of user likeness. A first user may establish a masking request for images taken by other users to conceal the first user's image or likeness in those images. The masking request may correspond to a token, such as a data package, that includes a request to mask the first user in the images, an image of the first user used to perform facial recognition to identify the user in the images, and a masking image to mask the user in the images. Additionally, the token may include an identifier used to contact the first user or a payment option to pay the first user to unmask the first user in the images. The token may be broadcast over an area around the first user to mask the first user in images on receiving devices.

This application provides a method for transmitting face image data and transferring value, apparatuses, an electronic device, and a storage medium, which belongs to the field of network technologies. The method for transmitting face image data includes acquiring a face data stream through the sensor, and transmitting the face data stream to the first processor; performing image screening on a face image in the face data stream by the first processor to obtain at least a target face image, the target face image meeting a target condition; retrieving a target web address from the memory by the first processor; and transmitting the target face image to the target web address by the first processor.

A method and device for securing image data detected by an electronic device is provided. The electronic may include a camera. In one aspect, a method includes: capturing image data using the camera; based on the captured image data, detecting a security marker displayed by a display device, the security marker being periodically displayed to be undetectable by a human eye that is viewing the display device; and in response to determining that the security marker is detected by the electronic device, applying a security policy to the image data captured by the electronic device.

An encryption circuit includes a fundamental vector generation circuit configured to generate a random number sequence for serving as a fundamental vector based on an initial vector, an image mask generation circuit configured to generate an image mask with a mask value set for each pixel in a region to be encrypted smaller than a frame size of the image, based on the fundamental vector and coordinate information for specifying the region to be encrypted, and an XOR operation circuit configured to compute an exclusive OR between each mask value of the image mask and each pixel value of the image data to generate encrypted image data.

Implementations generally relate to providing secure digital images. In some implementations, a method includes receiving an input image. The method further includes generating a plurality of partial images derived from the input image. The method further includes displaying the plurality of partial images to a user, where a sum of the partial images provides the input image.

A screen capture prevention method includes serving a single-color, DRM-protected video clip for display as a background for a document on a web browser. The document is processed to render its background color as transparent. Content of the document is viewable over the contrasting video clip background. When a screen capture event is detected, the video clip is changed to a same color as the content of the processed document, rendering the content indistinguishable from the background while the screen capture event is active.
