The paper presents a novel Graphics Interchange Format (GIF) Steganography system. The algorithm uses an animated (GIF) file format video to applyon, a secured and variable image partition scheme for data embedding. The secretdata could be any character text, any image, an audio file, or a video file;that isconverted in the form of bits. The proposed method uses a variable partitionscheme structure for data embedding in the (GIF) file format video. The algorithmestimates the capacity of the cover (GIF) image frames to embed data bits. Ourmethod built variable partition blocks in an empty frame separately and incorporate it with randomly selected (GIF) frames. This way the (GIF) frame is dividedinto variable block same as in the empty frame. Then algorithm embeds secretdata on appropriate pixel of the (GIF) frame. Each selected partition block for dataembedding, can store a different number of data bits based on block size. Intruders could never come to know exact position of the secrete data in this stegoframe. All the (GIF) frames are rebuild to make animated stego (GIF) *** performance of the proposed (GIF) algorithm has experimented andevaluated based on different input parameters, like Mean Square Error (MSE)and Peak Signal-to-Noise Ratio (PSNR) values. The results are compared withsome existing methods and found that our method has promising results.

Automated Teller Machine Authentication Using Biometric

Computer Systems Science & Engineering 2022年第6期41卷 1009-1025页

This paper presents a novel method of a secured card-less AutomatedTeller Machine (ATM) authentication based on the three bio-metrics measures. Itwould help in the identification and authorization of individuals and would provide robust security enhancement. Moreover, it would assist in providing identi-fication in ways that cannot be impersonated. To the best of our knowledge, thismethod of Biometric_ fusion way is the first ATM security algorithm that utilizesa fusion of three biometric features of an individual such as Fingerprint, Face, andRetina simultaneously for recognition and authentication. These biometric imageshave been collected as input data for each module in this system, like a fingerprint, a face, and a retina module. A database is created by converting theseimages to YIQ color space, which is helpful in normalizing the brightness levelsof the image hence mainly (Y component’s) luminance. Then, it attempt toenhance Cellular Automata Segmentation has been carried out to segment the particular regions of interest from these database images. After obtaining segmentation results, the featured extraction method is carried out from these criticalsegments of biometric photos. The Enhanced Discrete Wavelet Transform technique (DWT Mexican Hat Wavelet) was used to extract the features. Fusion ofextracted features of all three biometrics features have been used to bring in themultimodal classification approach to get fusion vectors. Once fusion vectorsware formulated, the feature level fusion technique is incorporated based on theextracted feature vectors. These features have been applied to the machine learning algorithm to identify and authorization of multimodal biometrics for ATMsecurity. In the proposed approach, we attempt at useing an enhanced Deep Convolutional Neural Network (DCNN). A hybrid optimization algorithm has beenselected based on the effectiveness of the features. The proposed approach resultswere compared with existing algorithms ba
