The Kioba Processing LLC invention works as follows
The method involves locating the buffer of memory locations that contains the contents of the formatted page. It also includes locating the first text between two markers in the buffer. This first text is an encrypted text with N characters.
Background for System and method for copy protection of displayed content
Information in the form text and images is often transmitted between computers through files like Microsoft Word documents (documents), Microsoft Excel spreadsheets (spreadsheets), Microsoft PowerPoint slides (presentations), HTML web pages, XML files and other files with text and images. A user can copy text and images displayed on such files using several widely-known methods. A user can, for example, select a text portion with an input device, such as a keyboard or mouse, and then copy it to paste into another document. Another example is that a user could capture the content of a computer screen by using a screen capture and then insert it into another document.
Text on web pages is especially susceptible to being copied. In most cases, HTML-displayed web browsers allow users to view the source files of HTML pages. In the Microsoft Windows operating systems running Microsoft Internet Explorer and Netscape Communicator, a user can select?View source? by clicking on the right mouse button while the mouse is positioned above an HTML page. In most cases, the source file of the HTML page will be displayed in full within a separate window. The user can easily select and copy any text portion from the source document, then paste it in another document.
Adobe’s PDF Reader disables the ability of users to copy text selections. This is a feature that some applications like Adobe’s PDF Acrobat can provide. A user can still capture any part of a PDF displayed on the screen using a simple screen grab.
Many information services generate their revenue by providing clients with valuable information. Financial services, marketing, news and legal services are examples of these services. Such information is also often delivered electronically. With today’s technology a subscriber can copy and email such information to others without having to pay for additional subscription fees.
There is a pressing requirement to find a solution to stop text and images displayed on computers from being copied.
U.S. Pat. No. Lesk’s 5,905,505 describes a method and system based on images for protecting text displayed in a screen. Lesk works on a bitmapped image of the displayed text. Lesk produces two perturbed pictures by adding random bits into the bit-mapped text image. The two perturbed photos are then rapidly interlaced. The user can then see the desired text image by averaging the two perturbed pictures, but only one is shown at a time. “A person copying data off the screen will only get a perturbed picture, which can be difficult to read.
Lesk can be difficult to implement because (1) random bits must be generated so that the average of two perturbed pictures appears ‘clean? Lesk must be practised on a video buffer level for Internet applications. It is also possible to defeat Lesk by taking two screens that contain both perturbed pictures and then averaging the digitally.
There is a need for a more simple and practical method to stop text and images displayed on a screen being copied without permission.
The present invention is a system and method for copy protection, which includes text and images within a page of a document, such as HTML, displayed on a display by a computer.
