<p>A computer-implemented method of scanning a document (e.g. a newspaper or a book) where the text may be legally protected from unauthorized copying, comprising the steps of: acquiring to a memory at least one recording confined to a field that covers a delimited area of a document; processing the at least one recording to perform character recognition; when a character is recognized, registering it in a memory, and performing the above steps repeatedly while recording at shifted positions so as to progressively obtain a string of characters; and evaluating the string against a predefined condition. If condition is not satisfied, at least a portion of the string and at least a portion of the at least one recording are cleared from the memory. If condition is satisfied, it is determined whether to provide an output.</p> |
