Conference iSemantic 2018 : A Robust Non-Blind Image Watermarking Method Using 2-Level HWT-DCT

Abstract:

The current technology allows to distribute digital images quickly and easily over the internet. Some digital images have copyright that needs to be protected. Watermarking is a technique for protecting copyright. In order for copyright is not easily lost with image manipulation, then watermarking technique must be robust. This study proposes a combination of Discrete Cosine Transform (DCT) based on two levels of the Haar Wavelet Transform (HWT) on image watermarking method with the aim of improving aspects of robustness and imperceptibility. The first step, host image is transformed with DWT as much as two levels to get LL2 subband. LL2 subband is a subband containing the image core information of two levels of wavelet transformation. Furthermore, LL2 subband split into small sub-blocks with the size of 4 * 4. The sub-blocks are transformed again using DCT. Insertion of watermarks using alpha variables with a certain value on the DC coefficient matrix. This value is used for managing the quality and strength of the watermark. To test the imperceptibility and watermark resistance used measuring instruments MSE, PSNR, and correlation coefficient. Based on the simulation results obtained a watermarked image is quite satisfactory with a relatively good imperceptibility value and resistant to various attacks.

JURNAL : Encryption of Text Message on Audio Steganography Using Combination Vigenere Cipher and LSB (Least Significant Bit)

Abstract

The growing information technology is very rapidly, the more evolving crime techniques to find information that is confidential. The Internet is one of the main media in disseminating information. The use of security on the internet still needs to be developed. Based on these problems, the type of research undertaken in the writing of this final task is the type of experimental research by developing methods that have been done by previous researchers to hide secret data that is inserted into the audio * .wav so that the security and confidentiality of data can be guaranteed. data security can be done with various methods, including cryptography and steganography. Cryptography is a technique for encrypting messages and steganography is a message concealment technique. This insertion type uses binary ASCII character code. In the cryptographic process, using the Vigenere Cipher algorithm and in the steganography process using the algorithm (LSB) Least Significant Bits. The merger of the two techniques resulted in a better new digital image security system and increased the value of MSE, PSNR and Execution time. Then the test results in the evaluation using BER and histogram analysis. Good audio quality has a minimum value of 30 dB PSNR[1]. In the embedding process using combinations of vigenere and LSB methods, Audio 15 is the best audio compared to other audio. Audio 15 has a smaller MSE (0.001656) value and a larger PSNR (124.138499) value than any other audio when embeded messages *.txt file with character 4096.

TIPS & TUTORIAL : INSTALL VB.6 DI WINDOWS 10

Error yang sering muncul ketika install VB.6 adalah Not Responding........

Berikut ini tips untuk menginstall di Windows 10 :

1. Siapkan Visual Basic 6.0 Enterprise Edition
2. Buka folder VB.6 EE, cari file SETUP.EXE, klik kanan properties, klik tab compatibility, centrang run this program in..... (Win XP SP2), klik OK.

3. Di File SETUP.EXE klik kanan Run Administrator

4. Pilih Custom

5. Pilih Data Access Component

6. Uncheck ADO & RDS

7. Klik OK, tunggu proses install sampai proses selesai.

8. Restart dan Jalankan VB.6

9. Untuk project lama yang menggunakan OCX tambahan silahkan di register dengan regsvr32 di command line, Win32 di c:\windows\system32 dan Win64 di c:\winsdows\SysWow64

Semoga tips & tutorial ini bisa membantu, terima kasih. #semuanyaajib

JURNAL : Deteksi Tingkat Risiko Kehamilan dengan Metode Fuzzy Mamdani dan Simple Additive Weighting

Abstract

The risk of pregnancy is a contributing factor in increasing mother maternal mortality (MMR). This study aimed to produce a pregnancy risk detection system based on patient examination results. This research combines fuzzy Mamdani and Simple Additive Weighting (SAW) methods using 11 criteria to determine the risk of pregnant women, that is low, high, and very high. The criteria that determine the risk of pregnancy are expressed as fuzzy statements. In system testing to 100 pregnant women patients, obtained an accuracy of 88% using recognition rate method.

Keywords :
pregnancy risk early detection; high risk pregnancy factor; Fuzzy Mamdani system; simple additive weighting; recognition rate accuracy

JURNAL : OPTIMASI QUERY MENGGUNAKAN ALGORITMA INGRES PADA PORTAL LUMBUNG DATA PENDIDIKAN JAWA TENGAH

Abstrak

Portal web Lumbung Data Pendidikan Jawa Tengah memiliki jumlah data record yang besar yaitu 46.442.378 record, dan terdapat tabel sebanyak 31, untuk mendapatkan informasi yang diinginkan diperlukan relasi tabel yang banyak sehingga diperlukan waktu lebih lama dalam memproses query, dikarenakan tidak menggunakan metode khusus dalam melakukan query atau hanya menggunakan teknik query konvensional hasilnya waktu yang dibutuhkan untuk memproses query menjadi relatif lambat. Tujuan penelitian ini untuk mengoptimalkan query menggunakan algoritma INGRES yang nantinya akan diuji dan dibandingkan hasilnya dengan query konvensional untuk mengetahui sejauh mana pemrosesan query dapat dipercepat. Hasil eksperimen yang dilakukan menunjukkan bahwa algoritma INGRES dapat mempercepat proses eksekusi akan tetapi masih memiliki kekurangan, pada pemrosesan awal penggunaan algoritma INGRES justru mengakibatkan penurunan kecepatan hingga 122%, akan tetapi pada proses berikutnya dapat menaikkan kecepatan hingga 60%. Hal ini dikarenakan pada pemrosesan query dengan menerapkan algoritma INGRES diperlukan pemecahan query dan pengeksekusian secara berurutan yang hasilnya ditampung ke dalam temporary tabel terlebih dahulu, hingga didapatkan query akhir yang paling optimal.

Kata kunci : Optimasi Query, INGRES, Optimasi Query Basis Data Tersentralisasi
