With the increase in the development of multimedia technologies, the multimedia data are transmitted in the various fields like commercial, video conferencing, medical and military fields, which generally include some sensitive data. Hence there is a great demand for transmission technique. Cryptography is becoming most popular for communication any type of sensitive data. There are various enc...

Secured multimedia data has grown in importance over the last few decades to safeguard content from unwanted users. Generally speaking, a number of methods have been employed hide important visual eavesdroppers, one which is chaotic encryption. This review article will examine encryption currently use, highlighting their benefits and drawbacks terms applicability for picture security.

The strong need for security guarantee, e.g., integrity and authenticity, as well as privacy and confidentiality in wireless multimedia services has driven the development of an emerging research area in low cost Wireless Multimedia Sensor Networks (WMSNs). Unfortunately, those conventional encryption and authentication techniques cannot be applied directly to WMSNs due to inborn challenges suc...

At July 2008, the nationwide DMB (Digital Multimedia Broadcasting) has got started. As DMB device's volume of sales has been over 12 million already, the development of rapidly changing network systems has increased the dangers of infringing the copyright of DMB contents. For solving this problem, we suggest that real-time encryption algorithm without additional expenses, and implemented that o...

Machine-to-machine (M2M) communication is viewed as one of the next frontiers in wireless communications. Because of unguarded communication, new security threats emerge. Considering that multimedia will be widely used in various applications over M2M network, it is very urgent to meet new security requirements for multimedia communication. This paper focuses on a joint fingerprinting and encry...

Wireless technology is used in many applications with location based data encryption techniques to secure the communication. The use of knowledge of the mobile user's location called Geo-encryption, produces more secure systems that can be used in different mobile applications. Location Based Data Encryption Methods (LBDEM) is a technique used to enhance the security of such applications called...

In the present scenario, no technology that's connected to internet is unhackable. All digital services like communication, military and medical imaging systems, multimedia systems require reliable security in storage transmission of images. The importance protecting images cannot be overstated. Therefore, there a need for image encryption techniques order hide from such attacks. this process, ...

The high security communication systems became an urgent need in recent years for both governments and peoples desiring protection from signal interception. Advanced Encryption Standard (AES) is a famous block encryption algorithm which has several advantages in data encryption. However, AES suffer from some drawbacks such as high computations, pattern appearance if apply for image encryption, ...

Because of the COVID-19 pandemic, most tasks have shifted to an online platform. Sectors such as e-commerce, sensitive multi-media transfer, banking skyrocketed. this, there is urgent need develop highly secure algorithms which can not be hacked into by unauthorized users. The method backbone for building encryption pseudo-random number generator based on chaotic maps. Chaotic maps are mathemat...

in the last two decades, the trend in healthcare information technology has been towards digital and multimedia concepts. the next generation of healthcare information systems will consist of a vast network of heterogeneous, autonomous and distributed imaging scanners, hospital information systems (his), medical information from clinical departments such as radiology information systems (ris), ...
