A method for altering text displayed in a formatted page, including locating a buffer of memory locations containing contents of a formatted page, locating a first text string between two markers within the buffer, the first string being an encrypted text including N characters, replacing the first text string with a second text string within the buffer, the second string being a decrypted text including M characters, where M is less than N, and inserting N-M special fill characters in the N-M unfilled memory locations between the markers within the buffer, so as to avoid the need to move the markers closer together.

Method and system for copy protection of displayed data content

A method and system for protecting digital images copied from a video RAM, including the steps of transmitting stored pixel data from a computer memory to a video RAM, identifying protected pixel data within the stored pixel data, modifying the stored pixel data, thereby generating modified pixel data within which individual pixel datum is recognizable as being protected or unprotected, and, in response to pixel data being copied from the video RAM, replacing individual pixel datum copied from the video RAM, that is protected, with substitute pixel datum.

Method and system for copyright protection of digital images

A method for providing textual information in a network environment, the method comprising: receiving a request via a network for text-editable textual information; converting the text-editable textual information into a non-text-editable textual format on line upon receiving the request; and sending the non-text-editable textual information via the network. Network-based systems are also disclosed.

Method and apparatus for preventing reuse of text, images and software transmitted via networks

A method for protecting digital images distributed over a network, including the steps of receiving a request from a client computer running a network browser, for an original layout page containing references to digital images therein, parsing the original layout page for the references to digital images, generating a modified layout page from the original layout page by replacing at least one of the references to digital images in the original layout page with references to substitute data, and sending the modified layout page to the client computer. A system is also described and claimed.

Copyright protection of digital images transmitted over networks

A method for altering text displayed in a formatted page, including locating a buffer of memory locations containing contents of a formatted page, locating a first text string between two markers within the buffer, the first string being an encrypted text string including N characters, replacing the first text string with a second text string, the second string being a decrypted text string including M characters, where M is less than N, and inserting N&#x2212;M special fill characters in the N&#x2212;M unfilled memory locations between the markers, so as to avoid the need to move the markers closer together.
