Abstract
Obfuscating denotational logic in a source program. A non-rule-based object oriented source program is received. The source program is transformed into a rule-based source program that includes an object model and a ruleset. Attribute domains of the rule-based source program are characterized by a structure of their values in which the structure of the values is nominal, ordered, interval, or ratio. A minimum cardinality is calculated for each domain attribute. First domain attributes are randomly mapped to second domain attributes, each second domain attribute having the same value structure and a same or higher cardinality as the corresponding first domain attribute. For each randomly mapped pair a domain range of the first domain attribute is mapped to a domain range of the second domain attribute. In the rule-based source program first domain input fields and values are replaced with the respective second domain input fields and values.
