Abstract

Disclosed is a system and method for modifying the presentation of content and/or graphical elements and behavior of a digital presentation (e.g., a webpage) by identifying an information event and dynamically overlaying a fully functional complementary presentation of the digital presentation, without accessing the underlying source code of the digital presentation, employing a special software or equipment (e.g., a special web browser), or requiring that original or user submitted content associated with the digital presentation be transmitted to a remote or otherwise uncontrolled server.

15. The method of claim 1, wherein the digital information comprises digital images.

16. The method of claim 1, further comprising a security monitor component including a database, the database of the security monitor component including an identical copy of the overlay file and the utility function file of the production component;

matching the overlay file and the utility function file of the security monitor component against the overlay file and the utility function file of the production component; and

the security monitor component operating to transmit an alert if an overlay file or utility function file of the security monitor does not match the overlay file or utility function file of the production component

17. A method comprising:

providing a production component, a security component, the production component including a database and being operable to transmit, process, and receive digital information;

production component including at least one of overlay file or a utility function file, the overlay and utility function files each including an instruction operable to affect at least one of the presentation, content, and behavior of the digital information;

validating by the security component the integrity of the overlay and utility function files;

receiving by the production component from a remote station at least one of an expression or function instruction;

comparing by the production component the at least one expression or function instruction received from the remote station against the overlay and utility function files; and

transmitting from the production component to the remote station an instruction from the overlay or utility function file that corresponds to the received expression or function instruction.

18. The method of claim 17 wherein the validating by the security component comprises:

(a) the security component including a validation component and a security monitor component;

(b) each overlay and utility function file including a first security file;

(c) the production component further comprising a second security file;

(d) the validation component including a third security file;

(e) the second security file of the production component being compared against the third security file; and

(f) the security monitor component including an identical copy of the overlay file and the utility function file of the production component, and the security monitor component operating to compare the overlay file and utility function files on the security monitor component against overlay and utility function files on the production component to validate the integrity of the files.

19. The method of claim 17, wherein the at least one expression or function instruction comprises uniform resource locator information.

20. The method of claim 17, wherein the transmitted instruction comprises cascading style sheet information.
