How DRM (Digital rights management) works: 4ZE4FER85SEF

The need for digital rights management (DRM) is paramount in a world where content (literature, music, videos, movies, artwork etc.) is available in digital form and hence can be distributed within seconds to any device anywhere around the globe. If copyrighted content were distributed without constraints, it would certainly benefit the consumers but would seriously affect the content creators/owners as theywould not get the royalty they are entitled to. In order to address this fundamental need, DRM has been conceived and is being implemented

Cloud Computing: What It Is—and What It Isn’t: CJJFWHUKGUQ2

In a world that sees new technological trends bloom and fade on almost a daily basis, one new trend promises more longevity. This trend is called cloud computing, and it will change the way you use your computer and the Internet. Cloud computing portends a major change in how we store information and run applications. Instead of running programs and data on an individual desktop computer, everything is hosted in the “cloud”—a nebulous assemblage of computers and servers accessed via the Internet. Cloud computing lets you access all your applications and documents from anywhere in the world, freeing you from the confines of the desktop and making it easier for group members in different locations to collaborate.

Forces Driving Adoption of Cloud Computing

Today’s cloud computing services provide common business applications online that are accessed from a web browser, while more traditional computing models of the 1960s through the 1990s involved users accessing software resident on a computer owned by the company or (after the introduction of the personal computer) on the very computer they were using.

Location Privacy in Location based services

Location-based services exploit location information to provide a variety of fancy applications. While amount of attractive quality of life enhancing applications are presented by location-based services, new threats are also brought in. Among these threats, perhaps the most important one is the intrusion of location privacy.
Location privacy is the claim of individuals, groups, or institutions to determine for themselves when, how, and to what extent location information about them is communicated to others.

Security in Multimedia Communications

In the near past, all mobile services were simple communication-oriented networkbased applications, such as circuit-switched voice calls or SMS messages. During the late 1990s, however, people started advertising content-oriented services and various multimedia solutions. In recent years, mobile multimedia communication services have grown rapidly due to the rich media content, broadband wireless networks, and flexible IP-based transport. Mobile multimedia can be defined as a set of protocols, standards, techniques, and mechanisms for multimedia information exchange over mobile networks.

Security and Privacy in Mobile Communications

Nowadays, mobile communication systems are increasingly used for private discussions and business traffic involving sensitive data, business secrets, or personal information. Most of the time, the end users of these systems give little interest to the security of their communications, the privacy of their data, and the protection of their mobile stations (i.e., terminal systems).
As the use of mobile communications devices has increased, many people have become more concerned with the privacy of communications. Most recently, location-based services have raised severe issues related to the privacy of user location. In particular, people realized that the mobile phones are easily tracked; indeed, the current architecture of mobile network systems essentially requires that the mobile stations be tracked. Additionally, many users have become more interested in the ways provided by the network operators
to guarantee correct billing and authentication, especially when they are roaming under foreign networks.

Mobile threats: Top five vulnerabilities

Hackers are increasingly taking aim at mobile devices, even though the majority of security attacks still target conventional PCs and servers.
Experts such as Richard Clarke, former cyber security advisor to President Bush, predicted that mobile devices will become the next major platform for hacker wars. After all, mobile devices are easy, unprotected targets that hackers can exploit. There are many factors making mobile technologies and devices less secure. Here is a list of the top five of them;
