This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbersor Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible. However, some file signatures can be ...
Definition. A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature.

Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
Serial Vector Format ( SVF) is a file format that contains boundary scan vectors to be sent to an electronic circuit using a JTAG interface. Boundary scan vectors consist of the following data: Stimulus data: This is data to be sent to a device or electronic circuit. Expected response: This is the data the device or circuit is expected to send ...
Boundary scan is a method for testing interconnects (wire lines) on printed circuit boards or sub-blocks inside an integrated circuit. Boundary scan is also widely used as a debugging method to watch integrated circuit pin states, measure voltage, or analyze sub-blocks inside an integrated circuit. The Joint Test Action Group (JTAG) developed a ...
X-ray computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source. A sinogram (left) and an image sample (right). [1] Picture of a CT scout ( scanogram or topogram) as used for planning every scan slice.
Optical coherence tomography. A high-resolution spectral-domain OCT scan (3×3 mm) of a dry age-related macular degeneration eye showing geographic atrophy and drusen in macula on both cross-sectional and en face fly-through. Optical coherence tomography ( OCT) is an imaging technique that uses interferometry with short- coherence-length light ...
