Question: What type of details about jessica fridrich can be gathered from the following bio? Bio: 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 . 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 -lrb- four pairs -rrb- . 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 erno 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 -lrb- cross , first 2 layers , orient last layer , permute last layer -rrb- .
