1.1) The MRC theory says after the first migration from Africa 1.8 million years ago, the different groups of humans in different part of the world slowly evolved in parallel with each other. The emergence of modern humans didn’t occur in a single area, but on different continents. In contrast, the OOA theory says humans evolved first in African and then migrated to different continents. The Neanderthals and Homo Sapiens evolved into different species and interbreeding would be rare which is why there are different races. The only similarity between the two theories is that humans started in Africa. Until about 14 years ago, Genetic DNA showed that the MRC theory was correct. But 13 years ago more evidence shows the OOA theory is more realistic. Anatomical evidence shows different physical characteristic between Neanderthals and Homo Sapiens. Archeological

First World Savings and Loan is a financial institution that processes credit card transactions and loan applications online. We are currently considering implementing an open source infrastructure. This could potentially save us over $4,000,000 per year in licensing fees for the software we are currently using. However, due to our business needs; we must still comply with the Sarbanes-Oxley Act (SOX), Payment Card Industry - Data Security Standard (PCI-DSS), and the Gramm-Leach-Bliley Act (GLBA). We must comply with SOX, because we are a publicly-traded financial institution; PCI-DSS, because we process online credit card transactions; and GLBA, because we are a financial institution. All

- Information: is a knowledge which can be transferred or received concerning a particular fact or situation. And is a sequence of symbols that can be explained as a message. Information can be recorded as signs, or transmitted as signals.

As a member of the Information Security team at a small college, you have been made the project manager to install an access control system (ACS) in a dormitory. The ACS will automatically unlock the dormitory doors via an electronic proximity reader and integrate with an existing security camera system. The cameras are designed to face and rotate to record a person as they use their identification card to unlock the door.

Role based access control is an ideology through which access to systems is restricted based on authority given. It is used by organizations with a relatively large number of employees ranging from five hundred to one thousand and above (Sieunarine & University of Oxford, 2011). This is implemented through the mandatory access control or through the discretionary access control. These are the only two ways through which role based access control can be implemented.

Access control has been in use before the growth of the technology world. It could involve a simple action as locking a door. A person locks a door to prevent entry to those who are not allowed or authorize to do so. The same can be said about the security involving databases and the controlling of who can have access and what can be accessed. As far as database security is concerned, there are various categories that are involved in access control. The four main categories of access control include: Discretionary, Mandatory, Role-based, and Rule-based access control.

Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.

Access control: The ability to permit or deny the use of an object (a passive entity such as a system or file) by a subject (an active entity such as a person or process).

Deniable ring signature: The ring signature scheme which has the property of anonymity revocation is known as deniable ring signatures. This was first proposed by Susilo and Nu . In this ring signature scheme, the verifier can interact with the signer or entities to confirm that the signer or entity has signed the signature with zero knowledge interactive proof. In this signature scheme, any signer cannot shift blame to other entities. Denial ring authentication is a combination of ring signatures and deniable authentication. Digital signatures provides authentication of messages thus providing non-repudiation of messages. In most of the applications, non-repudiation is one of the desirable properties, but in some applications it may not be. Inspired by such requirements Naor introduced Deniable ring signature scheme in 2002. In such ring authentication scheme, the verifier can be convinced that a entity of an adhoc group of participants is authenticating a message m, by not disclosing the identity information of the signer entity. It is also not possible for the verifier to convince any third party entity that message m is authenticated. This has been found in a number of applications. The Deniable ring signature scheme has the following properties:
