This study has been undertaken to investigate the determinants of stock returns in Karachi Stock Exchange (KSE) using two assets pricing models the classical Capital Asset Pricing Model and Arbitrage Pricing Theory model. To test the CAPM market return is used and macroeconomic variables are used to test the APT. The macroeconomic variables include inflation, oil prices, interest rate and exchange rate. For the very purpose monthly time series data has been arranged from Jan 2010 to Dec 2014. The analytical framework contains. Rather than an on location server cloud services will be services that are accessible from a dispersed cloud stockpiling worker. These measured frameworks are worked by an outsider and give clients access to PC assets, for example, investigation or systems administration over the Internet. Cloud Computing is utilized to give processing assets over the Internet and is utilized to store information on cloud workers. Security and information insurance have been a critical field of interest in cloud processing because of the sharing of assets. Cloud service suppliers store and hold client data through server farms that are influenced by information spillage.. It is observed that many mechanisms have stressed data protection and have neglected privacy in the subsequent process. Authentication aids with preserving and verifying the identity of a recipient. We also suggest an effective technique to use two biometric models for safe message transmission to create a session key between two interacting parties. Finally, the reliability and utility of the proposed solution was seen by detailed trials and a comparative analysis. Index Terms - Authentication, biometric-based security, cloud service access, session key.
