Base Claim:
1. A method for verifying resource content, said method comprising: a processor at a first computer computing a first characteristic of the content of a resource stored at a second computer coupled to the first computer via a communication infrastructure; said processor at the first computer creating, in a markup language document, a markup element comprising the computed first characteristic and a resource indicator that references the resource, said markup language document being stored at the first computer; said processor at the first computer extracting the first characteristic from the markup element in the markup language document that is stored at the first computer; said processor at the first computer retrieving the resource from the second computer according to the resource indicator; said processor at the first computer generating a second characteristic of the content of the retrieved resource; said processor at the first computer ascertaining that the second characteristic is identical to the first characteristic; responsive to said ascertaining, said processor at the first computer processing the retrieved resource, wherein said generating the second characteristic comprises computing a hash of the content of the retrieved resource according to a particular hash algorithm, wherein said creating the markup element comprises: including the resource indicator in the markup element; computing the first characteristic by computing, according to the particular hash algorithm, a hash of the content of the resource referenced by the resource indicator; and including the computed first characteristic in the markup element, wherein said creating the markup element results in the markup element comprising a first attribute-value pair and a second attribute-value pair, wherein the first attribute-value pair and the second attribute-value pair are within distinct non-overlapping portions of the markup element, wherein the first attribute-value pair comprises both a first attribute denoting the resource indicator and a value pertaining to the first attribute, said value pertaining to the first attribute consisting of a first character string that consists of the resource indicator, wherein the second attribute-value pair comprises both a second attribute denoting the first characteristic and a value pertaining to the second attribute, said value pertaining to the second attribute consisting of a second character string that comprises an identifier of the particular hash algorithm and the generated first characteristic, and wherein the first attribute and the second attribute are different attributes.
