Jessica Fridrich is a professor at Binghamton University, who specializes in data hiding applications in digital imagery. She is also known for documenting and popularizing the CFOP method, which is the most commonly used method for speedsolving the Rubik's Cube, also known as speedcubing.〔(Specializing in Problems That Only Seem Impossible to Solve ), By BINA VENKATARAMAN, Published: December 15, 2008, The New York Times〕 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 even has Rubik's Cube inventor Ernő Rubik's signature in her notebook. Rubik signed the notebook at the Rubik's Cube World Championship in Budapest in 1982, an event where Fridrich finished tenth. In the Rubik's Cube World Championship in Toronto, Canada in 2003, she finished fifth. 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). ==Professional life== Jessica Fridrich works as a professor at the Department of Electrical and Computer Engineering at Binghamton University and specializes in digital watermarking and forensics.〔(Jessica Fridrich ), Talk on Youtube〕〔(Bio:Jessica Fridrich ), Binghamton University, USA〕 She received her MS degree in applied mathematics from the Czech Technical University in Prague in 1987, and her PhD in systems science from Binghamton University in 1995.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jessica Fridrich」の詳細全文を読む スポンサード リンク
