The Use Of Recent And Modern Multimedia Devices

The thing with biometrics is that it works great only if the verifier can verify two things: Firstly, that the biometric to be used has come from the intended person at the time of verification, and Secondly, which the biometric should match with the master biometric entry in the file database. If the system can't do that, it can't work. Biometrics are good in uniquely identifying the people, butat the same time they are not secrets and cannot be trusted [1].

being attacked, encrypt it with a secret key to obtain an encrypted bit stream . For that AES encryption is used. After AES encryption, will embed at the fourth bit position of . Some related information about the mosaic image generation process into the mosaic image for use in the secret image recovery process are also embed at the last fourth bit position of . Such information, described as a bit stream I like M, includes the following data items: 1) encryption key; and 2) total length of before encryption. After all this process Target image with mosaic image, residual value and all information that required to recover original image are transmitted to receiver

Multimedia content is also in collaboration with Encryption & Decryption standards (CBR).The below paper is the general

This report illustrates the Message Digest 6 (MD6) hashing algorithm, how it functions, and the essentialness of a hashing function. Besides, it depicts the qualities of this hashing capacity over its predecessor, and its present shortcomings.

This biometric authentication can't be borrowed, stolen, or forgotten, and forging one is practically impossible. As many as advantages we have while using biometric authentication we also have those many disadvantages. But the major motto of the establishment of Biometric authentication is to completely remove the fraudulent activities​ and give raise to a secure transactions.

Biometrics are automated methods of recognizing a person based on a physiological or behavioural characteristic. Using a unique, physical attribute of your body, such as your fingerprint, it should be to effortlessly identify and verify the genuine person in the market today. There are techniques that makes use of either a single biometric or multi modal biometric .There are many advantages in using the single biometric system such as accurate identification, ease of use ,highly secured. However most of the techniques used in single biometric system are easily hacked and traced in the recent years. Also these single biometric have equal disadvantages such as noisy data. There are many advantages of multibiometric system over single biometric system , because more than one biometric feature is taken and fused together to enhance the security. Many systems were proposed by taking

In the present world lot of multimedia data is exchanged on internet and the percent of image data in that is highest. So we need to securely transmit that and this can be achieved by Image encryption.

Biometrics has the promise to become an irreplaceable part of most identification systems, however it is not yet 100% accurate. Passwords and cards (customary in government and banking conglomerates) are no longer sufficient as a means of individual recognition; they can be shared among employees, lost, or forgotten, on the other hand biometric distinguishers cannot be shared, copied, or misplaced. With our technology today, biometrics can be used to reduce fraud, lead to user friendly human and machine interface, and could consequently make our society safer.

Biometric authentication has been receiving extensive attention over the past decade with increasing demands in automated personal identification. Biometrics is to identify individuals using physiological or behavioral characteristics, such as finger-print, face, iris, retina, palm-print, etc. Among all the biometric techniques, fingerprint recognition is the most popular method and is successfully used in many applications.

Biometric technique is now becoming the foundation of a wide array of highly secure identification and personal verification. Recently world events have took place which leads to an increase the interest in security that will impel biometrics into majority use.

When Wireless communication devices first came out you had to reach for the instruction booklet to find out how to hook up your email, connect to the internet, and ultimately understand how to use the applications within it. But over time companies got smart and started listening to their users and what they wanted out of their devices. Soon enough, companies where developing user friendly apps that took care of all the hard work and remembered user inputs to make applications run faster and help the user reach their goal in a shorter amount of time. One big thing that came out in 2008 was videophones and wireless video communication. This was a way to wirelessly record and send video via wireless communications devices. As Patentdoc (2008) states: “there is provided a first portable communication device for communicating with a second portable communication device, the first portable communication device including a communication module for transmitting and receiving video and audio information” This was the main summary of the invention and the reason why sites like YouTube and Facebook thrive largely today on communications devices. Social media has become a big part of communications devices because these social media sites are ways to communicate with the world all at once. What better way to show your friends or the world what you’re doing by simply reaching to your phone or communications device, recording, and

The most important part in the Data Security is Authentication of user. The authentication is a process of verifying the identity of the users based on the credentials (username and passwords). “In security systems, Authentication is distinct from authorization which is the process of giving individuals access to system objects on their identity “(3). Authentication merely ensures that individual is who he or she claims to be, but says nothing about the access rights of the individual discussion. Passwords and passcodes are used to authenticate devices. Biometric scan technology are recently introduced to authenticate the users by finger prints, retina scanner and facial scanner. The reliability and security of the Biometric scan methods is superior to the Password Technology.

In particular, a large amount of duplicate data that exists in image files consumes significant storage space. To address this problem, we propose an effective image file storage technique using data de-duplication with a modified fixed-size block scheme. When a user requests to store an image file, this technique first calculates the fingerprint for the image file, and then compares the fingerprint with the fingerprints in a fingerprint library. If the fingerprint of the image is already in the library, a pointer to the existing fingerprint is used to store this image. Otherwise this image will be processed using the fixed-size block image segmentation method.

In recent times providing security to the information is the major issue. There are many applications developed by the cyber terrorists, cyber criminals, script kidders etc. to steal the private information like passwords, ATM pin numbers, and credit card details so on. One of the solution to protect the information is Cryptography, which is the focus of this paper.

Bagheri, M. et al, in 2010, the authors delineate the protection of digital pictures entices far attention recently. For pictures the makeover can be requested at two levels, the early one consists of the pixel worth
