Abstract: A method including determining a position of each glyph in an image of a text document, identifying word boundaries in the document thereby implying the existence of a first plurality of words, preparing a first array of word lengths based on the first plurality of words, preparing a second array of word lengths based on a second plurality of words of a text file including a certain text, comparing at least part of the first array to at least part of the second array to find a best alignment between the first and second array, deriving a layout of at least part of the certain text as arranged in the image of the text document at least based on the best alignment and the position of at least some of the glyphs in the image. Related apparatus and methods are also described.

Abstract: A computer program obfuscating system including a processor to provide a computer program including at least one computer program variable, and add an opaque predicate to the computer program to obfuscate the computer program so that the opaque predicate added to the computer program comprises at least one polynomial including a polynomial P, during execution of the obfuscated computer program, the polynomial P is evaluated yielding at least one result including a first result R1, and during execution of the obfuscated computer program, the opaque predicate is evaluated based on the at least one result R1 such that a decision as to whether or not to perform the first command is dependent upon comparing the first result R1 to at least one value in accordance with a predetermined mathematical relationship. Related apparatus and methods are also included.
