Abstract

The widespread distribution of digital images on the internet has diminished the copyright protection associated with them. In some cases, copyrighted and economically valuable digital images should not be modified or distributed without permission, as altering the original image can harm its owner. This violation is common, but many internet users are unaware of it. The goal of this research is to protect intellectual property rights of digital images using visual cryptography based on the Hill Cipher algorithm with matrix key flexibility. Hill Cipher is chosen for its ability to encrypt data in blocks, making it more secure than classical cryptographic algorithms that encrypt data individually. Visual cryptography is used to secure digital images through encryption and decryption. Encryption scrambles the image, while decryption restores it. The research method involves collecting digital image datasets, preprocessing, Hill Cipher encryption, and decryption. Key flexibility includes matrix keys of 2x2, 3x3, and 4x4 to enhance security. This research has demonstrated the effectiveness of the Hill Cipher algorithm in protecting digital images through encryption and decryption processes with flexible matrix keys of size 2x2 and 3x3. The results of the experiments, including encryption and decryption using both matrix sizes, have been thoroughly analyzed with respect to various cryptographic metrics: histogram analysis, energy, entropy, and running time.

Penelitian ini mempunyai tujuan untuk:1) mengetahui cara apa saja yang digunakan ketika pembelajaran pendidikan agama islam dalam membentuk akhlakul karimah pada siswa kelas III SDI Al-Azhar Kelapa Gading, 2) mengetahui faktor apa saja yang menjadi hambatan atau halangan dalam pembentukan akhlakul karimah pada siswa kelas III SDI Al-Azhar Kelapa Gading. Metode yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan metode deskriptif. Subjek yang digunakan pada penelitian ini adalah 2 guru yakni guru pendidikan agama islam dan wali kelas. Teknik pengumpulan data yang dikumpulkan adalah wawancara dan studi pustaka. Hasil penelitian dapat disimpulkan: 1) cara yang digunakan untuk membentuk akhlakul karimah yaitu menyampaikan akhlak yang dimiliki Nabi Muhammad SAW dan menjadikannya tumpuan untuk mencapai akhlak yang baik, melakukan koordiniasi dengan wali murid dan pemantauan terhadap akhlak peserta didik dirumah dan menanamkan sifat penuh tanggung jawab dan mandiri. 2) kendala yang dihadapi pendidik dalam pembentukan akhlakul karimah melalui pembelajaran pendidikan agama islam adalah kurangnya waktu yang disediakan, orang tua cenderung tidak ikut berperan aktif dalam pembentukan akhlak peserta didik, dan pengaruh negatif teknologi yang sering dilihat di internet.
