As software is becoming increasing important to the human society, so does the effort to produce them is also increasing.. All of these efforts can be at risk when source code of the application is reverse engineered by the software pirate. Many attempts have been made to protect Intellectual Property Rights (IPR); one of the newest attempts to protect IPR is software watermarking. It is used to prove ownership right when IPR are violated, and also prevents the bandit from altering the code for his own use. In this paper we are presenting a new technique for software watermarking know as Dictionary Based Software Watermarking (DBSW). DBSW works by embedding dummy instructions in source code with the help of predefined mapping already available in the dictionary. These instructions are identical to the normal instructions of the program and are hard to identify or to extract from the watermarked program. With the help of DBSW we not only can stop source code alteration but can also identify the buyer how has distributed the pirated copy.

To accommodate constantly growing knowledge in scientific discourse that is revised over time by domain experts, we need to also evolve our ontology. The body of knowledge will get structured and refined as we develop a deeper understanding of issues. Keeping trail of new changes in semantically rich and formally sound mechanism has pragmatic advantages for providing the undo and redo facility and ontology recovery to a previous state. In this research, we have proposed a framework that support change logging and then using these logged changes for reverting ontology to a previous consistent state and visualization of change effects on ontology. The system is compared with ChangesTab of Protégé and the results depict better accuracy for our system.

Due to heterogeneity in Data and Processes, healthcare systems are facing the challenge of interoperability. This heterogeneity results in different healthcare workflows of each individual organization. The compatibility of these heterogeneous workflows is possible when standards are followed. HL7 is one of the standards that is used for communicating medical data between healthcare systems. Its newer version V3 is providing semantic interoperability which is lacking in V2. The interoperability in HL7 V3 is only limited to data level and process level interoperability needs to be catered. The process level interoperability is achieved only when heterogeneous workflows are aligned. These workflows are very complex in nature due to continuous change in medical data resulting in problems related to maintenance and degree of automation. Semantic technologies plays important role in resolving the above mentioned problems. This research work is based on the integration of semantic technology in HL7 V3 standard to achieve semantic process interoperability. Web Service Modeling Framework (WSMF) is used for incorporating semantics in HL7 V3 processes and achieves seamless communication. Interaction Ontology represents the process artifacts of HL7 V3 and helps in achieving automation.
