An efficient traceable access control scheme with reliable key delegation in mobile cloud computing
In this article the author talked about the conjoining mobile application and cloud computing for mobile devices as one ‘mobile could computing’. This granting user better service and benefits in term of storage space and safety of data. In the bid to eliminate security threat in mobile cloud computing the authors have proposed a traceable access control with the use of key and re-encryption to trace malicious users leak the decryption keys for profits and delegating authority to three part to better secure mobile cloud computing (MCC).
My opinion on this write up is a positive one, based on two factors. (1) Security, this cannot be over emphasized and need periodic update on how to secure data. (2) Is Finance, proving it’s more cost effective that the regular mobile cloud computing.

In recent years, as digital media are achievement wider popularity, their security related issues are suitable superior concern. Digital watermark was first discovering in 1992 by Andrew Tirkel and Charles Osborne. Watermark is derived from the german term “Wessmark. The first watermarks devolved in Italy during the 13th century, but their use apace spread across Europe. Watermarking can be measured as special techniques of steganography where one message is embedded in another and the two messages are related to each other. Digital watermarking is similar to watermarking technique which allows an individual to add exclusive rights notices or other verification messages to digital media. Image authentication’s one of the applications of digital watermarking, which is used for authenticating the digital images. A digital watermark is a kind of marker covertly embedded in a noise-tolerant image such as audio or image data. It is typically used to identify ownership of the copyright of such image. "Watermarking" is the process of hiding digital information in an image the hidden information should but does not need to contain a relation to the image. The security and enforcement of academic property rights for digital media has become an important issue [2].
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
Created by Philip Zimmermann in 1991, this program has been widely used throughout the global computer community to protect the confidentiality and integrity of the users’ data, giving them the privacy of delivering messages and files only to their intended individual or authorized person (Singh, 2012). Not only being useful for individuals as a privacy-ensuring program, it has also been used in many corporations to protect their company’s data from falling into the wrong hands (Rouse, 2005).
The cloud computing is still under development but if it can manage to maintain information privacy and confidentiality than it will become revolutionary in healthcare field. And we never know, in future science and technology might introduce more advanced level of apps and service with enhanced level of privacy and security measures.

Several Air Defense Weapon Systems secured their places in the Hall of Fame of Air Defense history. Developed during times of world conflicts and the age of technology, these systems continue to play an integral and exciting role in U.S. Air Defense.
Over the last twenty years the progress in the technologies which handle information have appeared very dramatic and has therefore posed a threat to information privacy. Analysis of this progress reveals that this progress is not in terms of new technologies being invented but those technologies already known have increased dramatically in their power while also falling dramatically in their prices. This has happened to such a degree that the market penetration could only have been dreamed about by the most optimistic of market analysts a decade ago. The countries that are predominately concerned are those of the developed first world but as a result of the tremendous market penetration of these products their prices have now fallen to such a level that it cannot be long before the technology spreads progressively through the developed world also.
In the final part of Tele Health project, there are various aspects which we have to focus on. Tele Health services is already working successfully through remote connection, but it needs a server where it can store even large database, and it needs a security system also. Points mentioned below will be covered in this assignment.
As the aviation industry developed rapidly over the years it was difficult for air traffic control (ATC) to keep up with the increased demands, and maintain an acceptable level of safety. Needed improvements to the ATC network had been identified by several government appointed committees, which included such things as: radar surveillance equipment, transponders, increased navigational facilities, more control towers and increased ATC staffing. However, due to continued budget cutbacks by Congress it wasn’t until the harsh reality of several deadly midair collisions that lead way to actual appropriations being made to update the airway and ATC system.
In the rapidly developing field of computer science, there is no more controversial issue than encryption. Encryption has become a highly contested issue with the broad use of global networks including the Internet. As more and more sensitive documents are being placed on computer networks, and trusted information is being sent from computer to computer throughout the world, the need for encryption has never been greater. However, the effects of encryption on our lifestyle and the government's role in encryption has been (and will continue to be) debated for years to come.
In the past 60 years technology has grown by leaps and bounds. Computers are a common fixture of most homes. The Internet was created. Everyone carries cell phones that have more computing power than desktop PC’s did just ten years ago. And this march forward in technology also effected the aviation industry as well. The Boeing 787-8 Dreamliner is Boeing’s newest, most modern, and most technologically advanced commercial aircraft. However, it’s development also raised some security concerns. Fears that the Dreamliner’s network could be vulnerable to hackers or other cyber attacks lead the Federal Aviation Administration (FAA) to issue a Special Conditions Notice to Boeing to prove that the Dreamliner’s network is secure.
With the increasingly ubiquitous nature of mobile devices and online availability, including smartphones and tablets, there is also an understandable concern about the level of security that is afforded to such devices. This can be considered as increasingly important given the proliferation of policies such as BYOD (Bring Your Own Device) which is being used by diverse organizations as a way of lowering the cost of ownership for such devices while also leveraging the flexibility advantages that their utilization can bring. It is therefore an area of immense interest due to the changing and emerging nature of both the technology itself as well as the security concerns.
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
Have you ever asked yourself, what the world would be like if there weren’t any mobile applications. Society is impacted by the new development in technology daily. Someone is always claiming that their inventions will revolutionize the world, but no invention has had more success over the years, in the cellular world than mobile applications. People all around the world use millions to billions of applications daily for personal and business uses. For example, social networking which is use by all generations of people. It has an influence the way we purchase cell phones, in order to have the capability. With the creation of different smartphones and tablets, comes the demand for more mobile applications. This causes competition among application builders. Mobile applications are designed to its user making their experience less complicated. Mobile applications have their advantages and disadvantages, depending on its design and designer. They can be created to be very simple or complex, depending on its intended function. Has society benefited from the usages of mobile applications or is it just a distraction. What impact do mobile applications have on society.
