Content distribution site spoofing detection and prevention

A system for detecting and preventing content distribution site spoofing comprising:

• server-side page security logic;
• and, client-side page security logic cooperatively configured for operation with said server-side page security logic;
• said server-side page security logic comprising program code for computing a digital signature for a markup language document and for inserting addressing data in said markup language document;
• said client-side page security logic comprising program code for ensuring that said digital signature originates from a pre-specified source of said markup language document incorporated within said addressing data, and for comparing a dynamically computed hash value for said markup language document with a hash value encrypted within said digital signature to detect content distribution site spoofing either if said digital signature does not originate from said pre-specified source, or if said dynamically computed hash value does not match said hash value encrypted within said digital signature.

A machine readable storage having stored thereon a computer program for detecting and preventing content distribution site spoofing, the computer program comprising a routine set of instructions which when executed by a machine cause the machine to perform the steps of:

• loading a markup language document and a corresponding digital signature for processing;
• ensuring that said digital signature originates from a pre-specified source of said markup language document incorporated within said markup language document;
• dynamically computing a hash value for said markup language document and comparing said dynamically computed hash value to a hash value encrypted within said digital signature;
• and,
• detecting content distribution site spoofing either if said digital signature does not originate from said pre-specified source, or if said dynamically computed hash value does not match said hash value encrypted within said digital signature.
