Trusted client security factor-based authorizations at a server. The techniques allow the server to authorize client requested operations to access a protected resource or service based on trusted client security factors that are obtained at client machines and provided to the server.

Trusted client security factor-based authorizations

Trusted client security factor-based authorizations at a server. The computer-implemented techniques allow the server to authorize client requested operations to access a protected resource or service based on trusted client security factors that are obtained at client machines and provided to the server. A level of trust by the server in the client security factors is established by requiring that the client machine be pre-registered in a trusted machine registry before the server allows requests from the client machine to access a protected service or a protected resource. The registration of the client machine in the machine registry may be made by way of a probabilistically difficult to predict machine registration digest that encompasses a digest of a client program installed on the client machine and a machine identifier of the client machine.

A system and method for dynamically generating Web content using a parse tree is described. A template describing a dynamically generated Web page is built. The template includes a script written in a tag-delimited page description language. One or more markers included within the template each indicate a relative location within the Web page for dynamic content insertion. The hierarchical nature of the page description language is used to infer a set of display regions, which are referenced by a parse tree. The parse tree includes a plurality of nodes structured into levels. Each node corresponds to structural tags specified within the script. Each successive level represents a further nesting of the structural tags within the script. A controller program invokes a document engine and specifies a particular template. Each marker may be substituted with dynamic content zero, one or several times each. The document engine accepts substitution requests from the controlling program and implements specific inclusion rules that ensure well-formed output documents. The dynamic content is inserted into the display region for the substituted marker. Each node located in a level of the parse tree previous to the node corresponding to the substituted marker is processed. The output structure is scanned and the document is rendered with the dynamic content included therein.
