Protection Technology

Software protection technology is necessary for software security and property right of software. The algorithm of code obfuscation based on class is proposed that uses of obfuscation technology. The overall architecture of the system is hidden by changing the class diagram for class aggregation, and the algorithm of class aggregation can be used to design class hierarchy in object-oriented program. It makes static analysis difficult while preserving function of program. The interfaces replace original classes to achieve reference in order to implement type hidden, and automatic analysis becomes more difficult.

Object Oriented Metrics

Software testing methodologies and metrics are key issues to improve and assure software quality. They are important areas in the research of Software Engineering. However, not many focus on the testing criteria and metrics evaluation of a class hierarchy. This paper introduces an important concept named URI (Unit Repeated Inheritance) to realize integrated object-oriented testing and object-oriented metrics. The approach describes an ILT (Inheritance Level Technique) method as a guide to test object-oriented software errors and measure the software complexity of a class hierarchy. The proposed technique shows that inheritance has a close relation to object-oriented software complexity and reveals that overuse of repeated(multiple) inheritance will increase software complexity and be prone to implicit software errors. Also, two test criteria: intra level first and inter level first are presented.

An object-oriented computational framework for the transformation of colour data and colour metric tensors is presented. The main idea of the design is to represent the transforms between spaces as compositions of objects from a class hierarchy providing the methods for both the transforms themselves and the corresponding Jacobian matrices. In this way, new colour spaces can be implemented on the fly by transforming from any existing colour space, and colour data in various formats as well as colour metric tensors and colour difference data can easily be transformed between the colour spaces. This reduces what normally requires several days of coding to a few lines of code without introducing a significant computational overhead. The framework is implemented in the Python programming language.

Current Database

Users may derive new classes by defining views1 based on the current database contents. Some virtual classes are classified as brothers of existing classes, and others are either superclasses or subclasses of existing base and virtual classes. A base class is defined directly by the user using class definition constructs. A virtual class is classified as a brother of another class if it is derived from the latter class via a selection. To have a homogeneous system, virtual classes must be treated as first-class citizens in an object-oriented model.
