Video fingerprinting is of interest in the digital rights management (DRM) area, particularly regarding the distribution of unauthorized content on the Internet. Video fingerprinting systems enable content providers ( e.g., film studios) or publishers ( e.g., user-generated content (UGC) sites) to determine if any of the publisher's files ...
A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. [ 1] It is typically used to identify ownership of the copyright of such a signal. Digital watermarking is the process of hiding digital information in a carrier signal; the hidden information should, [ 2] but does not need ...
Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly ...
A cloaking device is a hypothetical or fictional stealth technology that can cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years. Developments in scientific research [ 1] show ...
The transmission media (often referred to in the literature as the physical medium) used to link devices to form a computer network include electrical cable, optical fiber, and free space. In the OSI model, the software to handle the media is defined at layers 1 and 2 — the physical layer and the data link layer.
July 24, 2024 at 1:18 PM. Meta said Wednesday that it has taken down about 63,000 Instagram accounts in Nigeria running sexual extortion scams and has removed thousands of Facebook groups and ...
The Invisible Internet Project (I2P) is an anonymous network layer (implemented as a mix network) that allows for censorship-resistant, peer-to-peer communication. Anonymous connections are achieved by encrypting the user's traffic (by using end-to-end encryption ), and sending it through a volunteer-run network of roughly 55,000 computers ...
Image sensor. An image sensor or imager is a sensor that detects and conveys information used to form an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information.
