Patent ID: 7400422

Claim:
A method for preventing computer recognition of data, comprising: receiving a request to print a document; receiving a readability value from a user, wherein the readability value is a value within a range indicating a degree of readability of a text, wherein the readability value determines the degree to which the text is non-scannable within the range between readability and non-scannability, wherein a first set of nonstandard fonts are introduced into the text at a first readability value in the range and a second set of nonstandard fonts is introduced at a second readability value in the range, and wherein the text at the second readability value is more difficult to read and more difficult to scan by an optical character recognizer than the text at the first readability value; automatically determining at least one user preference based on the readability value; modifying the text in the document based on the at least one user preference so that the text cannot be recognized by a character recognition algorithm; and printing the document.
