Penerapan sistem administrasi kependudukan mempercepat pendataan SGD desa yang merupakan program desa prioritas. Training on Using the Website-Based Population Administration Application for Tlangoh Village Officials  The problem faced by the Tlangoh Village Government is that the management of population administration is still manual, using the village population master book and the awareness of the people of Tlangoh Village that administrative order is still low, not reporting when there is a change in population data. Therefore, considering the population changes and must be updated, it is necessary to utilize information technology in population administration management. The potential for utilizing information technology includes the skills of village officials regarding information technology, and in accordance with the 2022 RKPDes, namely the acceleration of achieving village SDGs and the demands of digital villages. The solutions planned to solve these problems include technology substitution, training and mentoring. The purpose of this activity is to produce a population administration system application as a population database system in Tlangoh Village. The success of the service is a change in the population administration work pattern from manually using the Population Parent Book to using a website-based population administration system application. This makes it easier for Tlangoh village to manage population data in Tlangoh village. The population administration system application can update, add and delete population data, so that the population data of Tlangoh Village is valid and updated. The population administration system application database export can be used for the village's Sustainable Development Goals (SDGs) database.

Abstract

Digital image security is increasingly vulnerable to sophisticated attacks, underscoring the urgent need for robust encryption techniques. Traditional encryption methods often fall short in defending against advanced threats, highlighting the importance of innovative solutions to protect digital images. This study tackles these challenges by incorporating quantum computing into image encryption, employing techniques such as bit-plane scrambling, pixel permutation, and bit permutation. These strategies enhance security by introducing complex, non-linear transformations that make decryption attempts significantly more difficult without the correct cryptographic keys. A key configuration based on r=44, μ=2024 is employed to achieve this. The integration of quantum bit-plane scrambling and quantum pixel permutation results in a highly secure encryption method. Experimental results show substantial improvements in entropy levels, along with strong unified average changing intensity (UACI) and number of pixels change rate(NPCR) values across various images. Notably, the "Peppers" image achieved the best performance, with UACI values of 33.5572 and NPCR values of 99.8301. The method proves highly effective, as repeated tests with incorrect keys failed to decrypt the plain image accurately. Future research could explore the addition of a discrete quantum wavelet transform to further enhance the security and efficiency of quantum-based image encryption methods.

Abstract

Purpose: This research proposes an improvised version of the image encryption technique by incorporating Quantum Random Phase Encoding with the Arnold Transform to help enhance the strength and non-predictability of the encryption process. In this research work, some ideas gained from quantum-based methods have been brought to use with conventional approaches in image encryption techniques for enhancing their security. Methods: This model represents the basic methodology that underlies the Arnold Transform for scrambling the arrangement of image pixels to mask recognizable structures within quantum random phase encoding to introduce complexity through quantum-generated random phases. Result: The experimental results show much improvement in encryption efficiency. For example, in the case of "Cameraman" and "Lena", MSE parameters are 98.134 and 104.76, respectively; these now go up to 832.01 and 888.78. This implies that the higher decrement of these values 21.17 dB and 23.98 dB to 13.41 dB and 13.33 dB translates into higher distortion with higher security. Meanwhile, UACI and NPCR are also very steady and the mean value is about 0.3356 to 0.3358 and 99.60 to 99.61, which proves that this method has been effective in changing the pixel's value, and sensitive input changes. Novelty: This work is novel due to the introduction of quantum technologies in the classical methodology of image encryption. While classical techniques make use of conventional transforms for scrambling, like the Arnold Transform, this work embeds quantum randomness and intricacy in the process as a means of encoding namely, Quantum Random Phase Encoding.
