about the person Jessica Fridrich the speedsolving method of a rubik s cube Fridrich Method Jessica Fridrich is the inventor of the most commonly used method for speed solving the Rubik s Cube , better known as speedcubing . ref http www.nytimes.com 2008 12 16 science 16prof.html? r 1&em Specializing in Problems That Only Seem Impossible to Solve , By BINA VENKATARAMAN, Published December 15, 2008, The New York Times ref This method describes solving the cube in a layer by layer fashion. First a so called cross is made on the first layer, consisting of the center piece and four edges. The first layer corners and edges of the second layer are put into their correct positions simultaneously four pairs . The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms. Fascinated by puzzles and complex geometry, Fridrich has Rubik s Cube inventor Ern Rubik s signature in her notebook, which he signed at the Rubik s Cube World Championship in Budapest in 1982, where she finished tenth. In the second Rubik s Cube World Championship in Toronto, Canada Toronto , Canada , she finished second, behind Dan Knights . In the speedcubing community she is considered one of the pioneers of speedcubing, along with Lars Petrus . Nearly all of the fastest speedcubers have based their methods on Fridrich s, usually referred to as CFOP Cross, First 2 Layers, Orient Last Layer, Permute Last Layer .

Expert subject Cryptography date November 2008 Cryptoloop is a disk encryption software disk encryption Module Linux module for Linux which relies on the Crypto API Linux Crypto API in the Linux Kernel Stable version history 2.6 Linux kernel series. It was first introduced in the 2.5.x kernel series. Its functionality is incorporated into the device mapper , a generic framework used to map one block device into another. Cryptoloop can create an encrypted file system within a Disk partitioning partition or from within a regular file in the regular file system. Once a file is encrypted, it can be moved to another storage device . This is accomplished by making use of a loop device , a pseudo device that enables a normal file to be Mount computing mounted as if it were a physical device. By encrypting Input output I O to the loop device, any data being accessed must first be decrypted before passing through the regular file system conversely, any data being stored will be encrypted. Cryptoloop is vulnerable to watermarking attack s, ref cite web last SecuriTeam title Linux Cryptoloop Watermark Exploit date 2005 05 26 url http www.securiteam.com exploits 5UP0P1PFPM.html accessdate 2006 08 09 ref making it possible to determine presence of Watermark data file watermark ed data on the encrypted filesystem blockquote This attack exploits weakness in IV computation and knowledge of how file systems place files on disk. This attack works with file systems that have soft block size of 1024 or greater. At least ext2 , ext3 , reiserfs and minix have such property. This attack makes it possible to detect presence of specially crafted watermarked files, such as, unreleased Hollywood movies, cruise missile service manuals, and other content that you did not create yourself. Watermarked files contain special bit patterns that can be detected without decryption. ref cite web last Saarinen first Markku Juhani O. title Re Oopsing cryptoapi or loop device? on 2.6. date 2004 02 19 url h ... more details
GBDE , standing for GEOM Based Disk Encryption , is a block device layer disk encryption system written for FreeBSD , initially introduced in version 5.0. It is based on the GEOM disk framework.

The one time sector key is encrypted using a pseudorandom key. This pseudorandom key is derived from the sector number and a static 2048 bit master key with 128 bits of salt cryptography salt . The pseudorandom number generator used for this purpose is called the Cherry Picker. This is not a well established PRNG, but rather one invented for GBDE. This generator may not meet the security levels of standard algorithms, and could be distinguishable from random numbers. ref name elric initial analysis cite paper author Roland C.

single source date January 2012 Computational imaging refers to any image formation method that involves a digital computer . Computational photography refers broadly to computational imaging techniques that enhance or extend the capabilities of digital photography . The output of these techniques is an ordinary photograph, but one that could not have been taken by a traditional camera . Its current definition, which stems from a 2004 course at Stanford University and a 2005 symposium at MIT see links below , has evolved to cover a number of subject areas in computer graphics , computer vision , and applied optics . These areas are given below, organized according to a taxonomy proposed by Shree K. Nayar . Within each area is a list of techniques, and for each technique one or two representative papers or books are cited. Deliberately omitted from the taxonomy are image processing see also digital image processing techniques applied to traditionally captured images in order to produce better images. Examples of such techniques are image scaling , dynamic range compression i.e. tone mapping , color management , image completion a.k.a. inpainting or hole filling , image compression , digital watermarking , and artistic image effects. Also omitted are techniques that produce 3D scanner range data , voxel volume data , 3D model s, light field 4D light fields , 4D, 6D, or 8D Bidirectional reflectance distribution function BRDF s, or other high dimensional image based representations. Computational illumination This is controlling photographic illumination in a structured fashion, then processing the captured images, to create new images. The applications include image based relighting, image enhancement, image deblurring, geometry material recovery and so forth. Computational optics This is capture of optically coded images, followed by computational decoding to produce new images. Coded aperture imaging was mainly applied in astronomy or X ray imaging to boost the image ... more details
