Patent ID: 7392253

Claim:
A computer-implemented method for secure full-text indexing of a document, the method comprising: providing an index component, a document handler component, and a document processing component, wherein the document handler component has a first security setting, wherein the document processing component has a second security, wherein the index component has a third security setting; receiving, at the document handler component, a document identifier from the index component; cross-checking the document identifier received at the document handler component with an identifier associated with the index component to verify that the index component requested the document; temporarily shutting down the document processing component when the cross-checking verifies that the index component did not request the document; and when the cross-checking verifies that the index component did request the document, obtaining, at the document handler component, a document corresponding to the document identifier, processing the obtained document at the document processing component, and forwarding the obtained processed document to the index component.
