Recently, security has become one of the most significant and challenging problems for spreading new information technology. Since digital data can easily be copied, multiplied without information loss, and manipulated without any detection, security solutions are required, which encounter these threats? Security solutions are especially of interest for such fields as distributed production processes and electronic commerce, since their producers provide only access control mechanisms to prevent misuse and theft of material. In all these aspects, multimedia systems are the one which plays a major role in data sending, retrieving and transferring process through different multimedia held devices. So the point of Intelligent multimedia security services came into existence in order to track what problem actually persist and what measures are to be taken to minimize it.
Intelligent multimedia surveillance concerns the analysis of multiple sensing inputs including video and audio streams, radio-frequency identification (RFID), and depth data. These data are processed for the automated detection and tracking of people, vehicles, and other objects. The goal is to locate moving targets, to understand their behavior, and to detect suspicious or abnormal activities for crime prevention. Despite its benefits, there is societal apprehension regarding the use of such technology, so an important challenge in this research area is to balance public safety and privacy in multimedia systems.

In this section we investigate attacks and threats to our primary devices. These attacks and threats are built off of the vulnerabilities the previous section and help to determine which security controls would be most valuable against future attacks.
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].
PKC is the enabling technology for all Internet security and the increasing use of digital signatures, which are replacing traditional signatures in many contexts. However, RSA is better than PKC because RSA doesn’t need digital signature. As a result, the RSA algorithm turned out to be a perfect fit for the implementation of a practical public security system. In 1977, Martin Gardner first introduced the RSA system. After 5 years, company RSA used secure electronic security products. Nowadays many credit companies of all over the world use the RSA system or a similar system based on the RSA system.
Privacy and security issues have become one of the top concerns among computer users in today’s market. It has become a game of survival of the fittest in protection of your security. The only true way to defend yourself is knowledge. You should prepare your self against hackers, spammers and potential system crashing viruses and web bugs. Lets focus on how you can protect yourselves from the would be thieves.
Surveillance cameras have evolved and have become more sophisticated over the years. With advanced technology cameras are now equipped with high definition imaging, audio, and even night vision. It is important for law enforcement to be equipped with this advanced technology when it comes to deterring and solving crimes. To explain, high definition cameras provide better image quality which makes it easier to provide officers, citizens, and the media with a distinctive description of the suspect or persons of interest. With this high quality imaging police are able to read words off a newspaper or a book from a light pole twenty feet away; this is a vital aspect that can help law enforcement officials with solving various types of crimes. Next, audio will help catch any verbal exchanges between the suspect and the victim. For example, if a gang affiliated subject was allegedly involved in an altercation with a rival gang member and are standing within a certain radius of the surveillance...
CCTV which means closed circuit television, this is a system utilizes cameras to provide security by sending specific signal to destination, were it is used surveillance and observation of a place or people. In this paper I will seek to analyze how CCTV can be used as a comprehensive security solution by show the roles that a CCTV system would have to fulfill before it can be considered or viewed as a comprehensive security solution. These roles include deterrence, detection, delaying, assessment and response I will briefly explain each and give example. I will then move to explain how CCTV aids in the prevention and reduction of crime, by look at a reach and how the effect of CCTV in parking lots and other public places. I will also illustrate how CCTV can assist Law enforcement and other security practitioners in their investigations. Readers will be given short synapse of the different types of cameras and systems that are available, and examples of how they can be used and utilized. Last but not least I shall speak about the down side and concerns that come with having a CCTV system. This will be done by showing how the cost may affect the whole system, as it will take a good some of money to install, maintain and monitor the CCTV systems. Afterwards I will elaborate on one of the public major concern, which is surveillance system being intrusive and impeding on their right to privacy. The last concern that I shall discuss is the threat of hacker to CCTV system.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
The history of the modern media surveillance systems begins first with the invention of the computer and the use of software. Before the internet, information was only transported between computers by a physical storage device or an extremely expensive network. Software for media surveillance was only used to scan the media that was available in data form for particular key words. It could then be stored and indexed to be later analyzed. (Sarlós, 1982)
There are an estimated 30 million surveillance cameras in the United States, proving to be a normal feature in American lives (Vlahos). This is no surprise because in the past several years, events such as the 9/11 attack and the availability of cheaper cameras have accelerated this trend. But conflicts have come with this and have ignited, concerning the safety of the people versus the violation of privacy that surveillance has. Although camera surveillance systems are intended to provide safety to the public, the violation of privacy outweighs this, especially in a democratic country like America.
For thousands of years, cryptography and encryption have been used to secure communication. Military communication has been the leader in 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.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
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:
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
This report aim to explain how is achieved risk control through strategies and through security management of information.
