Ms. Geeta Sharma presented a research paper titled “Preserving IPR using reversible digital watermarking. She explained that wings of internet are facing significant obstacles for preserving the intellectual property of individuals and organizations. Threats to digital data and the rights of its creator are always an issue of concern as copying of digital data is easy. The ease of dissemination of digital data leads to penetration in intellectual property rights. Here, rights mean financial and moral interests of the author. The authors have faced risk in protecting their unique ideas, products and/or services. It can be achieved by embedding some copyright information with digital data. Digital watermarking allows the authentication of the data over intrusion of the attackers. In this paper, she considered a reversible technique for digital watermarking where original message or cover is recovered after the extraction of hidden data. A digest of the hidden data is created and embedded with the cover that can be extracted on the receiver end using the extracting algorithm. In addition, the use of private key increases the security level. The cover image can be retrieved in lossless manner and can be reused for further moderations.
Dr. Parminder Bajaj presented a research paper titled Analysis of structural linkages and inter-temporal stability in a cross-country BRICS portfolio.The paper attempts to evaluate prospects of constructing a successful cross-country portfolio by studying structural linkages and inter-temporal variations in the equity markets. To investigate market interdependence, shortterm capital co-movement was studied using Granger causality. Further, markets were tested for financial contagion and long-run interdependence using the Johansen co-integration test. The time-varying nature of capital markets was also tested through vector auto-regression modelling and impulse response function. The paper offers insights that co-integration amongst subject markets does not exist in long run and each market is mostly affected by price movements in its own market rather than fluctuation in other portfolio country stocks. The research cogently proposes economic feasibility of cross-country equity portfolio given the heterogeneity in markets and also advocates on intertemporal asset allocation strategies like pairs trade, long/short equity, managed futures and derivatives-based hedging.
