Abstract

A first check code is computed by applying an algorithm to a proper subset of a first body of data. A second check code is computed by applying the algorithm to an equivalent proper subset of a second equivalent body of data. The two check codes are compared. The extent of the proper subset of the first body of data is determined by a semantic analysis of the first body of data. Multiple versions of an application, when the semantic changes between the applications are inconsequential, may then be certified by ignoring the non-significant modifications and ensuring the integrity of the remainder of the content.
