ABSTRACT
Security in today's world is one of the important challenges that people are facing all over the world
in every aspect of their lives. Similarly security in electronic world has a great significance. In this
paper, we survey the security of database.
This is an area of substantial interest in database because we know that, the use of database is
becoming very important in

Data/information is always a most important asset for any organization whose security cannot be
compromised. With the advances in technology, the risk to these valuable assets increases. So their
security is a big challenge. In [8] different database security layers are defined shown in figure (2)
below. These layers are: database administrator, system administrator, security officer, developers
and employee. For each layer some well–defined security policies have been anticipated. These
policies ensure the security features, privacy, confidentiality and integrity.
This study mainly focuses on issues in databases security and measures taken to solve those issues.
Securing sensitive data from illegal access, theft and forging becomes a big challenge for different
organizations, like government, no–government and privates sectors. Encryption of data in client or
server side where data is shared between different parties is not sufficient.
Basically the problem is to ensure that semi trusted database is secure or not. [6]

The kernel maintains a list of free pages for each zone. Each zone has its own page allocator that
allocates and frees memory as needed. Mac OS X is a little different as compared to the older MAC
OS virtual memory. Similar to Windows OS, when Mac OS X needs memory it pushes something
currently not needed into a swap file for temporary storage (OSX Daily, 2010). The swap file
concept is also known as virtual memory. Mac OS X, because it is built on the UNIX core, relies
heavily on swap files and paging for general memory and cache management. Virtual memory, also
known as secondary memory or secondary storage, typically refers to hard disk storage and is much
slower than main memory. Advantages of virtual memory include; running more than one
application at a time, the ability to run larger programs with less RAM, applications may launch
faster because of file mapping, and the user does not have to buy more main memory (RAM).
Disadvantages of virtual memory include; applications run slower than if loaded into main memory,
increased time to switch between applications, less hard drive space for the users use, and some may
argue reduced system stability is inherent to virtual memory. Linux's virtual memory system is
responsible for the memory visible to each process. The memory system creates virtual memory on
demand and swaps pages in and out of main memory to the disk as needed. Virtual memory is
divided into regions called backing. Backing is

– Customizability: The system needs to be able to adapt to any type of operation. This can be done
by allowing the PM to rename to re–structure the project activities and re–label certain tasks, team
names, resources, terms, folders, and so on. – Expandability: The system needs to be able to grow
with the organization and at the same time handle a large or unlimited number of concurrent
projects. The system also needs to be able to visually and logically separate between projects while
allowing the PM to draw from a global or a customized pool of resources. – Reliability and security:
The system needs to be accessible at any time by any team member. It also needs to provide a high
level of security that guards the organizational data and all relevant information about its projects
and activities. – Scheduling: The system needs to support Gantt charts and automatic cost
recalculation which updates times, costs, and resources. The software should also be able to display
AON or AOA networks and plots of earliest start, scheduled start, slack/float, latest finish, planned
finish, and actual finish times. Naturally, the tool should allow creating activities and tasks,
assigning resources or individuals, setting deadlines, and drafting timeline diagrams of concurrent
tasks/projects. The system should also allow forming teams, groups, and allow

Steganography Is The Method Of Hiding A Secret Message
Abstract: Steganography is the method of hiding a secret message with in a cover medium. The
intention of steganography is secret communication to hide the existence of a message from a third
party. It has found use in variously in diplomatic, personal, military and intellectual property
application. This paper emphasis is on digital applications and current and future use of
steganography, focusing on hiding information in online image files. Examples of software tools
that employ steganography to hide data inside of other files as well as software to detect such hidden
files will also be presented.
Introduction: In today's information technology era, the internet has played a crucial part in the
communication and information sharing. ... Show more content on Helpwriting.net ...
All of those use redundant bits to replace by message bits. Therefore "Text" steganography is not a
famous technique; rather it is less likely used as a cover medium as it contains less redundant
information. Similarly audio and video steganography are less used method for their large size and
complex algorithm for compression and coding. Again in protocol steganography, messages are
inserted in network layer. Which may result in increasing the network congestion. So image
embedding is a famous technique in the area of steganography because it contains larger amount of
redundant bits and changes in least significant bit is unrealizable to human eye. In short:
steganography_medium = hidden–message + carrier + key
Digital Image Carrier Methods:
In digital steganography techniques mostly graphical images file are used as the carrier medium
because of large amount of redundant bits and its simplicity. Messages can be hidden in digital
media in number of ways. The most common steganography method in image files employs some
type of least significant bit substitution or overwriting. In this method high–order or most significant
bit is the one with the highest arithmetic value (i.e., 27=128), while the low–order or least
significant bit is the one with the lowest arithmetic value (i.e., 20=1). In this approach only few bits
of image are overwritten by the message (ASCII) value, the numeric value of the byte

Overview Of Intellectual Property Rights
Overview of intellectual property rights and how it relates to Computing
The purpose of the following essay is to discuss inttelectual property rights and its relation to
software, I will then futher discuss the patentabillity of software.
Since the use of the first computer, software has been considered as an addition to the hardware. The
law was adapted to treat software as such. and as such law was made to treat it rightfully like so I.e.
Example law (insert quote here ).
An ongoing opening is rife in the world of law that computing has its own law however these this
has been dispeled by individuals such as Judge Frank Easterbrook who states there is no such thing
as computer law, and goes on to compare justify this statement by useing Dean Gerhard Casper
declaration in xxx that there was no "law of the horse". (Easterbrook, 1996)
Whast is commonly computer law actually refers to a myrid of eclectic amalgamation connected of
concepts that exist in from existing law and said laws are subseqently , which are applied to the
relatively new the claiming of inttelectuall rights for technologies of computer hardware and
computer software, e–mail,security theroms and the Internet and other networks like it.
The objective of this essay is to explorer the nature of software and draw comparisons to objects in
different paradigms to ascertain as to whether the current method of creating patents for software is
correct..
For the sake of this essay I will use Marianne Doig

The Security Of Cloud Computing
The following will take a look into what is could computing and what are the potential security
issues, I will be covering topics such as why would a company use cloud computing and how could
computing is beneficial for an organisation. I will also look into the security of cloud computing. I
will then go on to discuss what is being done to combat these issues, touching on the policies used
by Netflix, Sony and Apple. Technical usage of the term cloud computing is the description of
distributed systems, the running of a single instance of an application over many connected
machines. However the term has now evolved as a synonym for the internet as a whole, with the
platforms and application provided on it described as a service. Saying ... Show more content on

John Manly (Director of HPs automated infrastructure Lab) suggests that "Cloud computing is the
final means by which computing becomes invisible". The relationship between software will be
divorced from hardware, with more and more technologies being consumed as a service. (SaaS)
When a company has a need for an IS/IT strategy, cloud computing often comes into question as a
new a developing technology that can offer a lot to company. Cloud computing can aid the company
in many aspects especially when it comes to storing data as they can send all their files/data to the
cloud to be able to access them anywhere. There are 3 different types of cloud computing: private,
public and hybrid cloud. The private cloud is only used by one company, this is either used
internally or it is outsourced to another company. The public cloud is when the cloud and all of its
services are accessible by anyone. A Hybrid cloud is a combination of the two. One of the main
companies that use the cloud is Netflix, when Netflix found that it was out pacing its traditional data
centre 's capabilities, it turned to the cloud for help with scalability in order to meet the spikes in
demand and the lulls in activity. On the average week night in North America Netflix accounts for
nearly a third of the all the internet traffic. Apple's hallmark is to be on the cutting edge of
technology, so it comes as no surprise that Apple turned to cloud

Cloud Computing
In many cases like this one, an organization should always have a backup strategy. Some of the
actions that I would take would be performing a backup on a USB flash drive which will be kept in
a safe place with the office. As for the profit and loss statements, cash flow statements and other
pertinent files will be updated daily, backed up and performed daily. If files are needed to be shared,
a cloud backup system can be implemented. A disaster recovery plan should be set forth with three
different sites * Hot Site– "A separate and fully equipped facility where the company can move
immediately after a disaster and resume business." * Cold Site– "A separate facility that does not
have any computer equipment, but is a place where ... Show more content on Helpwriting.net ...
* Maintainability– Diverse employment will be preferred so that there are no language barriers for
the customers. Obviously when the company starts picking up business and there are considerations
of going global then our system will have to be redeveloped. * Portability– There will be different
operating systems. Whether it's through the Apple iTunes which will be available for us if we decide
upon a Mac computer or any other PC computer. * Usability– Employees will get the proper
training in order to make their work experience as understanding and satisfying as possible. Any
type of hints or tips will be available for understanding the system better.
There are a multitude of benefits in the utilization of cloud computing. A primary function of cloud
computing is the availability of universal access to files throughout any given level of an
organization. As documents and other database driven information are stored off–site, there is often
a reduction of costs, due to the minimization of on site hosting software and hardware alike. The
many reasons to utilize cloud computing are evident, however, as all other technological advantages,
there are also a large variety of companies that offer these services with different benefits, costs and
application choices. Some of the most recognized corporations offer cloud computing such as
icloud, Google Apps, Amazon Cloud Drive, and many others. All organizations offer

are leveraged to optimal levels. Sky Drive, Google Drive, iCould and Dropbox are four of the most
popular Cloud based service vendors, what makes them outstanding are not only their advanced
technique but also their unique services.
Sky Drive * Microsoft products support SkyDrive
Released by Microsoft, the world's largest software maker, one of Sky Drive's biggest advantages is
Microsoft backup. Microsoft added Office Web Apps support to SkyDrive in its "Wave 4" update
allowing users to upload, create, edit, and share Microsoft Office documents directly within a Web
browser. Moreover, Users of recent versions of Microsoft Office (for Microsoft Windows ) can use
the desktop applications to simultaneously edit the same section of documents stored on SkyDrive.
Since Microsoft dominant in both the PC operating system and office suite markets, Sky Drive
could easy be accepted as an auxiliary tool in the main market. * Recycle bin

Windows 7 is an operating system that is of the Microsoft Windows family. Windows 7 is part of
one of the most used operating systems around the world. It is the successor to Windows XP and
Windows Vista. Alongside Windows 7 are two other operating systems that are viewed as
alternatives to the Windows OS. Those alternatives include Linux operating systems as well as
Windows Server 2008.

In our world today there are so many different types of operating systems as well as features and
applications that run on them. There are many similarities as well as differences between Windows
7, Linux and Windows Server 2008. The one enduring similarity is that all three are intended to be
utilized as an operating system is meant to.
Windows Server 2008
Windows Server 2008 is a line of server operating systems (OS) from Microsoft. It is the successor
of Windows Server 2003 and shares the same code base as Windows Vista. New features were
added in Server 2008 particularly Server Core command utility from security perspective to reduce
attack surface.
Windows Server 2008 Versions
Windows Server 2008 comes with three basic editions. The usage depends on the level of
criticalness of applications. Following is a summary view of all three.
Datacenter Edition
Datacenter Edition is for the most mission–critical applications. It offers highest level of
virtualization which helps in achieving highest levels of scalability, reliability, and availability

Torrent Freak Research
Today's digital knowledge has made it so easy to perform copyright infringement in order to create
pirated movies. This in turn has increased the amount of illegal digital movie distribution. It's so
easy these days to make perfect copies and then distribute it across global networks. Torrent Freak
research shows multiple copies of movies that are found online. Technology has made it more
tempting than ever to violate the copyright laws without breaking a sweat. Majority of Internet users
think that if it is on the Internet, it's free. But they don't realize that even public display of someone's
work without proper permission is considered Copyright infringement. Displaying it on a website,
putting it on film or transmitting it to the public in any other way are all examples of how movies
are facing piracy issues daily. In spite of that piracy continues to grow at an exponential speed.
Moreover, movies that deal with copyright infringement has grown over the years.
The seriousness of Copyright infringement was also brought to life by the hurt locker case. Voltage
pictures accused almost 25,000 BitTorrent users of illegally downloading or sharing the movie on

Insights Gained and Lessons Learned
Using The VinLogic Simulation Model
Introduction
Operations management is comprised of a series of concepts and frameworks that are best learned
through the use of simulations and constraint–based modeling to show the effects of one decision on
corporate performance. This is especially true in the areas of logistics, transportation and supply
chain management optimization, The VinLogic Simulation Model has specifically been designed to
take into account the iterative nature of these disciplines, showing how trade–offs in one area of
supply chain and logistics affect the performance of an enterprises' entire supply chain (Vinlogic,
2012). Simulation Dynamics has created a highly effective learning application that can be
iteratively used to learn how the constraints involved with logistics and supply chain planning and
management impact the overall performance of any organization.
Transportation and Delivery Lessons Learned
Where the VinLogic Simulation Model is most effective as a learning tool is how easily it is to
iteratively plan and execute workflows both from a tabular and graphical standpoint. It is evident
there are advanced constraint–based software being used to ensure the application stays accurate and
flexible across the many scenarios it completed during a lessons session. What is also very useful
from a learning standpoint is how effectively this simulation tool or application can define a wide
variety of logistics,

Linux Versus Windows Xp : Pros And Cons
Comparison Report
Linux versus Windows XP: The Pros and Cons
This may be the perfect time to move over to Linux, since Windows XP was officially retired in
2014. Although we can continue using Windows XP, the two most important factors to consider are
1) there will no longer be security patches released by Microsoft; and 2) they are no longer
supporting this product.
Additionally, our older XP machines may not support newer Windows releases, especially 8.1,
because it needs significantly more power and storage. Also, some XP applications may not work on
newer versions of Windows. So to run 8.1 on older PCs, there will be a lot of configuring to do
which takes time and money. All machines will need at least 4 GB of ram.
That said, both Windows XP and Linux each have their advantages and disadvantages. To help
determine what technology option is best in the long run for the company (i.e., to keep Windows XP
or switch to Linux), the team recommends that you perform a careful analysis with respect to cost,
performance and risk to make the right technology decision. We don't envy your position–which is
challenging–one that can affect the company 's total cost of ownership (TCO) and return–on–
investment (ROI), positively or negatively.
Windows
Windows XP will continue to work, security is a major concern. Although security companies still
support XP, at some point we could find ourselves vulnerable. Without security patches, cyber
criminals will have more opportunities to

The Problem Of Cloud Computing Essay
Abstract: Cloud computing is a computing technology or information technology architecture used
by organization or individuals. It launches data storage and interactive paradigm with some
advantages like on–demand self–services, ubiquitous network access. Due to popularity of cloud
services, security and privacy becomes major issue. There is the issue of legitimate responsibility for
information (If a client stores some information in the cloud, can the cloud supplier benefit from
it?). Numerous Terms of Service assentions are quiet on the topic of proprietorship. Physical control
of the PC hardware (private cloud) is more secure than having the gear off site and under another
person 's control (open cloud). This conveys awesome motivation to open distributed computing
administration suppliers to organize building and keeping up solid administration of secure
administration. This paper addresses design of proposed system. Keywords:Cloud Computing,

MP3 and Ogg file formats comparison
MP3 file format
There exist numerous types aural files.Thus, if you desire to alter the sound formats or replicate the
files so that they become playable in different audio players, you ought to be knowledgeable with
various file types.These file types can be differentiated through examination of the file name
extension.With that in mind, there are compacted audio file types which are preferred by many when
downloading, copying, and storing. MP3(.mp3) and OGG(.ogg) are two of the frequently used
compressed audio file types. The types are christened as lossy compression audio formats. MPEG–1
Audio Layer III or in short MP3 is a revolutionary digitized aural file format which permits the
audio file to be compressed ... Show more content on Helpwriting.net ...
–Between the two formats, MP3 is more common than OGG Vorbis.
–Regarding sound quality, OGG Vorbis is better than MP3.
– MP3 is restricted by copyrights while OGG Vorbis is free for all.
–In MP3 the bit rate of compression remains unchanged and cannot be varied while in OGG Vorbis
the compression bit rate can be varied according to your requirements.
– Fraunhofer–Gesellschaft and Thompson Multimedia developed the MP3 while the Viph.Org
Foundation created OGG Vorbis.
So between MP3 vs. Ogg Which Should You go for?
Now that you know the difference between the two formats which one is best for you?Owing to its
early introduction into the world of file sharing, MP3 became tremendously fashionable. Its
recognition is based on the reality that the phrase MP3 was synonymic with Compressed audio. The
word MP3 is often used by some people to mean any aural file. On the other hand, the OGG Vorbis
file format is increasingly becoming trendy among developers due to its better–quality sound and
free for all code base. Nowadays, the hardware and toy makers are employing OGG Vorbis in the
encoding of their audio files to evade MP3 patent problems and attain well–organized compression.
Though, most of the portable music players or MP3 players do not support the format of OGG
Vorbis.The game development industry highly favors the OGG Vorbis format as it has been

Microsoft has the potential to innovate in this cloud environment because it can use analytics to
quickly understand business usage trends across thousands of organizations – a level of visibility it
did not have in the traditional approach. It can then rapidly develop applications and approaches as
well as test and deploy new interfaces. Users will realize the benefits of this rapid innovation as their
work environments become more nimble, leading to stronger engagement; IT departments will

1. Server state :
Server state can be divided into two part : the stateful and stateless server. The stateful server is that
when a client open a file the server gives that client an unique identifier and stores client's
information into its memory. Although this method can improve performance, however, stateful
server is generally be avoided in distributed system. On the other hand, stateless server uses totally
different mechanism that the server identifies the file information and client position in each request
but save nothing into its memory. The advantage is that it is easier to use fault tolerance on stateless
server.

Granularity 8k chunk Whole file caching on client disk 64MB chunk 64MB block
Relationship Remote file access Upload/download service Remote file access Remote file access
Memory/disk usage Server side for disk access, client side for I nodes and file data. Client requests
file from the cold cache of the server and stores file on its disk. Files are stored at server disk.
Clients do read and write operations on the network. Clients contact HDFS through the NameNodes
and fetch the file from DataNodes (server storage).
Consistency NFS doesn't provide concurrency–control mechanisms. AFS uses weak consistency
model, which called call–back mechanisms. When write operation are done on existing file, the data
is appended to end of the file. This method serializes the data write in GFS. HDFS uses NameNode
operation to realize data consistency. NameNodes utilizes a transactional log file to record all the

The Hybrid Clouds ( Inter Vehicle Clouds Essay
3.3 Hybrid Clouds (Inter–Vehicle Clouds): HC is the combination of VC and VuC where VC serves
as both service provider and consumer at the same time. The motivation behind HC is that, vehicles
moving on the road might rent their resources and might want to use cloud services at the same
time. NaaS and P2P are the most suitable examples for such scenarios. Nevertheless due to the
ephemeral nature of VANET, connection among vehicular nodes is very intermittent. But yet it can
be argued that usually for P2P applications, the size of the files is fairly small making it suitable for
short time connection. Other potential applications for this architecture include IaaS in case of VC.

Secondary storage * Stokes (2008) states that secondary storage is used for saving files and
information in the matter of capacity. When programs are installed into the computer or files are
inserted, secondary memory is the place where all the stuffs are put into. It gives information about
how much computer can store data in its system. Files, programs, and other stuffs that put in
secondary storage are saved permanently in the system. So, when the computer is off, the stuffs will
stay at the same state and condition without having any lost parts.

The Cloud Of Cloud Computing
Introduction This report will be exploring what cloud computing is, the usages of cloud computing,
a comparison of organisations that offer cloud services and their architectures, an explanation on
how a typical software company may benefit from having a cloud implementation, a description of a
challenge that cloud computing has in research and a description of a challenge in a commercial
adaptation in connection to cloud computing. Part A What is cloud computing exactly? The idea of
cloud computing was first initially introduced by J.C.R Licklider in 1969 who introduced the idea as
"Intergalactic Computer Network" [1]. He envisioned a future where everyone on the planet was
connected/interconnected together accessing information, data, programs and so on from anywhere
in the world. A comments was made by Margaret Lewis who is the product marketing director at
AMD who said in 2010 that J.C.R Licklider idea in 1969 "the idea sounds a lot like what we are
calling cloud computing" [1, 2]. Some believe the idea was first discussed by John McCarthy who
discussed it in a public venue at a speech that was celebrating MIT centennial who said "that
computer time–sharing technology might result in a future in which computing power and even
specific applications could be sold through the utility business model (like water or electricity)"[3].
So what is cloud computing exactly? There are many definition of what people thing cloud

Introduction Of Cloud Storage System
CHAPTER 1 INTRODUCTION Cloud storage system is a service model in which data are
managed , maintained, and backuped remotely on the cloud side, and simultaneously keeps data
available to the users over a network. Mobile Cloud Storage (MCS) [1], [2] represents a family of
increasingly popular on–line services, and even is used as primary file storage for the mobile
devices [3]. MCS helps the mobile device users to store and retrieve files or data on the cloud
through wireless communication, which improves the data availability and facilitates the file sharing
process without drawing off the local mobile device resources [4]. The data privacy issue is a main
concern in cloud storage system, so the sensitive data is encrypted by the owner before outsourcing
onto the cloud, and data users retrieve the interested data by encrypted search scheme. In MCS, the
modern mobile devices are encountering with many of the security threats as PCs, and various
traditional data encryption methods are imported in MCS [5], [6]. However, mobile cloud storage
system incurs new challenges over the traditional encrypted search schemes, in consideration of the
limited computing and battery capacities of mobile device, as well as data sharing and accessing
approaches through wireless communication. Therefore, a suitable and efficient encrypted search
scheme is mandatory for MCS. Generally speaking, the mobile cloud storage is in great need of the
bandwidth and energy efficiency for data

The Multics Operating System Project Undertaken At The...
The Multics operating system project undertaken at the Massachusetts Institute of Technology
(MIT) in the 1960s was a novel and powerful approach that helped shape the subsequent course of
computing technology. In particular, Multics served as the model for utility computing and the
various kinds of on–demand software, platforms, and infrastructure services that exist today. Multics
was the first instance of the cloud. Leaving networked computers inside, Multics also offered a
novel approach to hierarchical file structures that served as a model for future security approaches.
Description of Multics: From Inception to Last Instance Multics is the shortened name of the
Multiplexed Information and Computing Service. Multics grew out of the idea, proposed by MIT's
John McCarthy and some other computer scientists in the 1950s, that computers ought to have time–
sharing capabilities (Garfinkel, 1999). At the time, computers were used by one person at a time,
which was economically and scientifically inefficient (Bourne, 1978). There were various
demonstrations of effective time–sharing on computers before the debut of Multics (Creasy, 1981).
The true novelty of Multics lay in McCarthy's vision, promoted in a 1961 lecture, for computing as a
utility (Steele Jr, 1975). McCarthy suggested that, in the future, computing power could be allocated
among geographically dispersed users, much in the manner that an electrical utility disperses
electricity to a large and geographically

Being an auditor for many years, I have utilized Microsoft Office in my daily work routine –– from
writing reports in Word, to using Excel as my worksheet and then PowerPoint for presentation
purposes. It is safe to say that I am very much familiar working on Microsoft Office. When I moved

Macintosh® (Mac) and Microsoft® Windows® are the main software to every computer system to
run properly along with other hardware. These operating systems (OS 's) are very different in
several ways, but they also have some similarities too. Linux, Mac and Windows use memory
management, process management, file management and security management to operate the
computer systems correctly. The first management to compare and contrast between the three OS is
memory management. Memory management is a process of handling computer memory to different

because they are both UNIX–based operating systems. One key difference is that with Mac most
people would modify and control processes from with the GUI and most users would modify the
processes using ps on Linux. Windows Process Management In general, Windows is not a multi–
user operating system, unless it is a Windows Terminal Server, meaning that it was not designed to
handle more than one user at a time, whereas Linux and Mac are both multi–user operating systems
and is capable of handling multiple users at a time. Windows however, can run multiple processes as
different users concurrently. With all three operating systems, users cannot terminate or modify the
