Abstract

Currently, the spread of hoax news has increased significantly, especially on social media networks. Hoax news is very dangerous and can provoke readers. So, this requires special handling. This research proposed a hoax news detection system using searching, snippet and cosine similarity methods to classify hoax news. This method is proposed because the searching method does not require training data, so it is practical to use and always up to date. In addition, one of the drawbacks of the existing approaches is they are not equipped with a sentiment analysis feature. In our system, sentiment analysis is carried out after hoax news is detected. The goal is to extract the true hidden sentiment inside hoax whether positive sentiment or negative sentiment. In the process of sentiment analysis, the Naïve Bayes (NB) method was used which was optimized using the Particle Swarm Optimization (PSO) method. Based on the results of experiment on 30 hoax news samples that are widely spread on social media networks, the average of hoax news detection reaches 77% of accuracy, where each news is correctly identified as a hoax in the range between 66% and 91% of accuracy. In addition, the proposed sentiment analysis method proved to has a better performance than the previous analysis sentiment method.

Abstract

The security aspect is very important in data transmission. One way to secure data is with steganography and cryptography. Surely research on this should continue to be developed to improve security. In this paper, we proposed a combination of steganographic and cryptographic algorithms for double protection during data transmission. The selected steganographic algorithm is the use of a combination of DCT and DWT domain transformations. Because the Imperceptibility aspect is a very important aspect of steganographic techniques, this aspect needs to be greatly improved. In the proposed method of DCT transformation first, proceed with DWT transformation. From the experimental results obtained better imperceptibility quality, compared with existing methods. To add OTP message security applied algorithm to encrypt the message image, before it is inserted. This is evidenced by experiments conducted on 20 grayscale images measuring 512x512 with performance tests using MSE, PSNR, and NC. Experimental results prove that DCT-DWT-OTP generates PNSR more than 50 dB, and NC of all images is 1.

Abstract

Information security is very important and has been widely implemented. Cryptography and steganography are two common methods that can be implemented to secure and conceal the information. In this research, the proposed AES algorithm for cryptography and DWT for steganography. However, in case of implementing DWT as steganography, there is a weakness which is a lower capacity. Based on DWT’s problem, proposed Huffman Coding to reduce the total of the message’s bit and increase the capacity. In the implementation, a message will be processed by using AES and compressed by using Huffman Coding then conceal in a cover using DWT. After doing several experiments using a 128x128 pixel message image and a 512x512 pixel of the cover image, achieved the average of MSE is 1.5676 and the average of PSNR result is above 40db which is 46.1878.

Abstract

Orchid flower as ornamental plants with a variety of types where one type of orchid has various characteristics in the form of different shapes and colors. Here, we chosen support vector machine (SVM), Naïve Bayes, and k-nearest neighbor algorithm which generates text input. This system aims to assist the community in recognizing orchid plants based on their type. We used more than 2250 and 1500 images for training and testing respectively which consists of 15 types. Testing result shown impact analysis of comparison of three supervised algorithm using extraction or not and several variety distance. Here, we used SVM in Linear, Polynomial, and Gaussian kernel while k-nearest neighbor operated in distance starting from K1 until K11. Based on experimental results provide Linear kernel as best classifier and extraction process had been increase accuracy. Compared with Naïve Bayes in 66%, and a highest KNN in K=1 and d=1 is 98%, SVM had a better accuracy. SVM-GLCM-HSV better than SVM-HSV only that achieved 98.13% and 93.06% respectively both in Linear kernel. On the other side, a combination of SVM-KNN yield highest accuracy better than selected algorithm here.

Abstract

One popular image security technique is image encryption. This research proposes an image encryption technique that consists of three encryption layers, i.e. bit-shift encryption, chaos-based encryption, and stream encryption. The chaos algorithm used is Arnold's chaotic map, while the stream cipher algorithm used is RC4. Each layer has different cryptology characteristics in order to obtain safer image encryption. The characteristics of cryptology are permutation, confusion, diffusion, and substitution. The combination of the proposed encryption method aims to secure images against various attacks, especially attacks on statistics and differentials. The encryption method testing is done by various measuring instruments such as statistical analysis, i.e. entropy information, avalanche effect, and histogram, differential analysis, i.e. UACI and NPCR, visual analysis using PSNR and SSIM, and bit error ratio. Based on the results of experiments that the encryption method that we propose can work excellently based on various measurement instruments. The decryption process can also work perfectly this is evidenced by the ∞ value based on PSNR, and zero value based on SSIM and BER.

Abstract

Transmitting image through the internet needs to be secured because of risk to be stolen. Security techniques that can be used for securing data especially image are cryptography and steganography. Combine these techniques can provide double protection in image security. In this research, we proposed the used of T-DES encryption with a selective bit to improve the time performance because time aspect is one of the important aspects of data transmission process. Four MSB of the secret image will be selected, then it will be encrypted using T-DES. After that, this encrypted results will be combined with other 4 LSB. This encryption scheme result will be embedded into a cover image using inverted LSB because inverted LSB can produce high imperceptible value. From 6 testing images which encrypted using proposed scheme present that proposed encryption scheme is twice faster than classic triple DES and slightly faster than double DES. While the embedding scheme can produce PSNR value above 40 dB with the range between 51 dB to 61 dB as well as SSIM which close to 1. This result denoted that proposed scheme generated good quality of stego images.

Abstract

Apel merupakan buah yang cukup populer dikonsumsi dan memiliki berbagai jenis bentuk dan warna.  Apel  sendiri  memili  berbagai  warna  kulit,  seperti  merah,  hijau,  dan  kekuningan.  Malang merupakan salah satu pusat budidaya apel di Indonesia. Jenis apel lokal indonesia yang banyak diminati adalah apel manalagi atau lebih sering disebut sebagai apel Malang. Salah satu keunikan apel manalagi adalah warnanya, warna apel ketika mentah dan matang cukup sulit dibedakan karena perbedaanya tidak terlalu siginifikan. Apel yang masih mentah berwarna hijau, sedangkan apel yang sudah matang berwarna hijau kekuningan. Hal ini membuat orang awam cukup sulit untuk membedakannya. Teknologi klasifikasi saat  ini dapat  dimanfaatkan untuk  membatu  proses pemilahan tersebut.    Penelitian  ini mengusulkan metode  naive  bayes  dan  ekstraksi  fitur  citra  untuk  mengklasifikasi  tingkat  kematangan  buah  apel manalagi. Dimana tingkat kematangan akan dibagi menjadi dua jenis, yaitu apel matang dan apel mentah. Ekstraksi fitur  yang digunakan pada penelitian ini rerata intensitas, energi, entropy, standar deviasi, smothness dan skewness. Keenam fitur tersebut diklasifikasi dengan naive bayes. Data yang digunakan pada penelittian ini adalah 130 citra, yang terdiri dari 100 citra latih dan 30 citra uji. Hasil akurasi metode ini mencapai 63%. Kata kunci:  apel manalagi, naïve bayes, klasifikasi, ekstraksi fitur, citra digital.

Abstract

Watermarking merupakan salah satu ilmu penyembunyian data dengan tujuan untuk mengamankan citra, salah satunya yaitu copyright protection. Beberapa algoritma dalam watermarking yang dikenal handal pada domain spasial salah satunya Least Significant Bit (LSB) yang diketahui telah diimplementasikan pada steganografi dan kriptografi. LSB mempunyai kelebihan dalam hal imperceptibility, dengan kata lain pada citra hasil embedding maupun extracting dengan citra asli tidak terdapat perbedaan secara kasat mata. Untuk meningkatkan imperceptibility ke dalam tingkat yang lebih tinggi maka LSB akan dikombinasikan dengan Canny. Kelebihan Canny yaitu tidak merubah persepsi dari citra yang diolah. Pada makalah ini, eksperimen dilakukan menggunakan citra grayscale berukuran 256x256 sejumlah masing-masing 4 citra berformat *.bmp dengan pesan yang akan disisipkan berupa file *.txt. Hasil dari eksperimen menunjukkan nilai PSNR yang tinggi, dimana nilai PSNR hasil embedding dengan Canny hanya 53,8370 dB, sedangkan dengan mengimplementasikan LSB-Canny didapat nilai PSNR tertinggi 75,6510 dB. Perbedaan yang cukup jauh tersebut diakibatkan oleh penentuan lokasi embedding yang dilakukan oleh Canny. Perolehan nilai MSE yang mendekati 0 maka semakin bagus kualitas citra yang dihasilkan. Nilai MSE terbaik yang dihasilkan oleh LSB yaitu 0,2688 sedangkan pada LSB-Canny nilai MSE terbaik yaitu 0,0018.
