This information has to be transferred securely to retain privacy. Many techniques have been developed so that this information is transferred securely without being intercepted by the third party. Steganography is also such techniques in which information can be transferred securely. In steganography, the existence of secure information is completely hidden from the third party. Only sender and receiver know that about the secret information being transferred. In steganography, information is embedded into some cover medium like text, image, audio or video etc. In image steganography, the image is used as a cover medium to hide the secret data. Most common technique for image steganography involves least significant bits (LSB) of image pixels which are altered with the secret message bits. There are a lot of limitations in the LSB techniques, due to which many new image steganography techniques are developed. Pixel Indicator Technique is such a technique. In this paper, an altered version of the PIT is presented in which advantage of 24 bits of each pixel is taken to hide the data in three data channels of RGB. In this method, no separate key is used for encryption and decryption, thus avoiding any overhead of managing key. This technique provides enhanced capacity and security over any other image steganography techniques.

The chance of survival rates among people can increase if lung cancer is detected at an early stage. As per current survival rate, only 14% patients can survive for 5 years. It can be increased by 35% and make survival rate nearly 50% if the disease is detected in her early stage. This is only possible with effective screening test to detect the lung cancer. Many techniques such as filtering, image thresholding, histogram equalization based on image pre-processing and Gray Level Co-occurrence Matrix (GLCM) techniques based on feature extraction are used for detection of the this disease. But to reduce the mortality from lung cancer a fast, accurate and effective screening test is required for early stage detection of the target disease. The proposed approach using Adam algorithm and Convolutional neural network on CT scan images is among best solution.

It is a most popular cybercrime today. Phishing attacks also affect the online payment sector financial institution, file hosting or cloud storage, and many others. Phishing attack always targets to these Web sites which are related to the online payment sector and Web mail. Many techniques are used to prevent the phishing attack like blacklist, Heuristic, visual similarity, and machine learning. Blacklist technique is most commonly used because it is easy to implement, but this technique cannot detect a new phishing attack. So, now, machine learning is most efficient technique to detect the phishing attack and this technique is able to detect all drawback of other phishing detect techniques. So this research work is completely based on machine learning algorithms which are logistic regression, decision tree, random forest, and SVM to detect phishing Web site. In...

In this, the information is hidden within an image and the image travels openly on the Internet. The Least Significant Bit (LSB) is one of the most popular methods of image steganography. In this method, the information bit is hidden at the LSB of the image pixel. In one bit LSB steganography method, the total numbers of the pixels and the total number of message bits are equal to each other. In this paper, the LSB method of image steganography is used for watermarking. The watermarking is an application of the steganography. The watermark contains 80*88 pixels and each pixel requirs 8 bits for its binary equivalent form so, the total number of bits required to hide the watermark are 80*88*8(56320). The experiment was performed on standard 256*256 and 512*512 size images. After the watermark insertion, histogram analysis was performed. A noise factor (salt and pepper) of 0.02 was added to the stego image in order to evalu...

These files are of great significance from the point of view of privacy. So proper security is needed in order to achieve the secure transfer of files, many different techniques are used so that data in these files can’t be intercepted by the third party. To achieve security, different technologies like cryptography and steganography are used. In cryptography, information is encrypted but its existence is not hidden. But in Steganography, the existence of secure information is also hidden. Steganography is the novel and decent technique of embedding important secret information in the cover medium like text, audio, video etc. The main use of steganography is to hide the important information as well as its existence from the third party. This paper discusses image steganography and various techniques used in image steganography. In image steganography, to achieve the secure transfer of informat...

Digital Watermarking is a process to prevent the unauthorized access and modification of data. It ensures that the communication between two parties’ remains secure. Digital watermarking can be performed in spatial and frequency domain. In the spatial domain, the watermark is embedded in the very existence of the pixel. In frequency domain, the transformation of any kind is applied and then information is embedded. In this paper, we proposed an approach to watermarking in frequency domain using DWT technique. The gray scale host image is divided into four sub bands: LL, HL, LH, HH and the watermark are inserted in the LL sub band using DWT technique. As the image is divided into four sub bands, a watermark of equal size of the LL sub band...

It assures that the communication between two parties remains secure and their communication should be undetected. This paper investigates the consequence of the watermark strength of the grayscale image using a Discrete Wavelet Transformation (DWT) additive technique. In this method, the gray scale host image is divided into four sub bands: LL (Low-Low), HL (High-Low), LH (Low-High), HH (High-High) and the watermark is inserted in an LL sub band using DWT technique. As the image is divided into four sub bands, a watermark of equal size of the LL sub band has been inserted and the results are discussed. LL represents the average component of the host image which contains the maximum information of the image. Two kinds of experiments are performed. In the first, the same watermark is embedded in different images and in the later on the strength of the watermark varies by...

Security of data is one of the huge components of information technology and communication. Steganography is a term used for information hiding and it is an art of hidden writing. In steganography we hide information with a multimedia carrier i.e. image, text, audio, video files, etc. So, that observer cannot find the hidden information which we want to send to the receiver. Steganography main objective is to provide robustness, detectability, capacity of hidden data due to which it differs from other techniques such as watermarking and cryptography. This paper proposes a various technique used to hide information on image by an image steganography. In image steganography we hide our secret data in image so that the observer cannot feel its existence. Image steganography strategies are as of late been useful to send any secret message in the ...

For this we need a secure system to protect our secret data from eavesdroppers. Two different technologies are used to make our information secure i.e. cryptography and steganography. In cryptography we do encryption of the secret message but we can’t hide the existence of the secret message. But in steganography we hide the existence of the secret message. Steganography is the art which help us to hide secret information in different multimedia files. As a result, unauthorized users are not able to see and recognize the hidden information. It is a science that manages a secret path for sending information secretly using different multimedia carrier like in image, text, audio and video file. This Paper includes image Steganography, its basic working and insertion techniques used in Image Steganography such as LSB, Chaotic, GLM, Parity checking and Interpolation. It also involves Steganography applications and a ...

However there have been several existing steganography mechanisms to secure the graphical contents but there are still threats from external attacks. Moreover in case of bulky image it becomes difficult to shift content over network without any loss. Thus proposed work has been introduced to allow graphical splitter mechanism to break graphical content in multiple parts by splitting image matrix in two or multiple parts according to image size. If the image size is less bulky, it could be split into just two parts or if the image size is more bulky, it could be split into more than two or multiple parts. This would save the image from being hacked or read in unauthentic manner. The proposed work would apply a key to divide image matrix in two or more than two parts so that it could not be easily understood. The proposed work is also concentrated on Threats to security, Nature of attacks...

Security is the main issue, during sharing information. To resolve the security problem, two techniques are used to make our information secure, i.e., cryptography and steganography. Cryptography is used for encryption but does not hide the information. So, it is not too much secure. The emerging Internet technology has led to the need for a high level of security which is provided by steganography. Steganography is used to hide the existence of a secret message. As a result, unauthorized users cannot access secret information in different multimedia files. This paper gives a brief overview of steganography, type of steganography, insertion technique used in image steganography search such as LSB, GLM, parity checking, and interpolation. It also includes the application and a set of parameters to test the imperceptibility of an algorithm. In image steganography, the cover medium used for hiding data is an image. The most common technique for image steganography involves the least significant bits (LSBs) of image pixels which are altered with the bits of secret message. There are a lot of limitations in the LSB techniques, due to which many new image steganography techniques are developed. The cyclic LSB technique is such a technique. In this paper, an altered version of the cyclic LSB technique is presented. The advantage of this method is that RGB channels of the image are rotated into the cycle, i.e., red channel is used for hiding first bit, the green channel is used for hiding the second bit, the blue channel is used for hiding third bits, and then this cycle is repeated. In this method, no separate key is used for encryption and decryption, thus avoiding any overhead of managing key. This technique provides enhanced capacity and security over any other image steganography techniques.

In this paper, a three bit XOR steganography system for concealing messages into gray Images is projected. In this method, last three bits of pixel value offer 100 percentage of message addition. This new technique uses the XOR operation between the message and original image. If the intruder extracts the last three bits, he would not be able to find the meaning of the message as the message is in decoded form. The maximum no of bit which is to be hidden using this method is equal to the R∗C∗3, where R and C is the rows and column of the image. The time complexity is also calculated which is equal to O(1). Later on the method is analysed on the bases of PSNR, MSE, L2RAT and MAXERR. The projected technique is also matched with other similar techniques to show the superiority.

But with the advent of quantum computers that are assumed to have unlimited computational capability, classical cryptography is now proved to be no more unconditionally secure. It has been proved that the security of a cryptographic system depends on the key used for encryption, not the algorithm. Quantum Key Distribution (QKD) is a key sharing mechanism between two parties whose security relies on the very laws of nature (quantum mechanics), not on the computational capability of the eavesdropper. In QKD, if an eavesdropper tries to gain key information, then he will be detected immediately, and the key sharing procedure is aborted. In this paper, we will survey some of the most prominent QKD protocols proposed till now, and then we will perform a comparative analysis on those protocols depending on various factors.

Since the dawn of the Internet, there has been an exponential increase in the number of web sites and so the quantity of data on these websites. The hackers attack the web sites to collect useful information and also to make other legitimate users devoid of the information or services they required. Such problems and other similar types of attacks can be handled by "Honeypot" system which takes all attacks on itself and studies the attack patterns to detect similar kind of attacks in future.Honeypots allow all the attacks on itself and make attackers think that they have the access of real system and meanwhile honeypots will study all the attack pattern of attackers. The authors have created a network of various Honeypots to enhance the efficiency. Before honeypots, a filtering algorithm is used which with the help of pre-defined sink server will predict whether a given packet is malicious or not,...
