Abstract:
1. A method for detecting and preventing content distribution site spoofing comprising 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; wherein said ensuring step comprises the step of comparing a domain for said digital signature to a domain embedded in a field in said markup language document to ensure that said digital signature originates from said embedded domain.
