Abstract

The advancement of communication media has rapidly evolved with the emergence of various communication applications on smartphones, which have now surpassed mere communication functions to become complex social media platforms. This change has transformed the way we interact, not only through messages and voice but also through the exchange of videos and images. However, along with these developments, there has been a surge in digital crimes such as defamation, fraud, and drug trafficking. This investigation aims to compare the performance of forensic tools in obtaining digital evidence by utilizing applications like Mobiledit, Belkasoft, Mobile Forensic SPF, and Magnet Axiom, and by applying the National Institute of Justice framework, which consists of five stages: identification, collection, examination, analysis, and reporting. The output of the investigation is presented through reports and evidence, resulting in text chat files, contacts, images, audio, and view-once images. Forensic tools have a 100% success rate in finding pieces of evidence. The comparison of the four tools showed different percentages: Mobiledit Forensic 40%, Magnet Axiom 80%, Belkasoft 60%, and Mobile Forensic SPF 60% in obtaining evidence. Digital evidence can be used as strong support in court proceedings.

Abstract

Personal data has become a highly valuable asset in the digital era. The background of this research is the urgent need to raise awareness in the digital era about the importance of protecting digital education certificate. The purpose of this research is to analyze the integration of blockchain technology with cryptographic algorithms for the secure storage and verification of digital education certificates. The methodology follows the Prisma framework, which is carried out through four systematic stages: formulating research question, preparation research protocol, identification of records from four major databases (Google Scholar, IEEE, Springer, and MDPI) published between 2023 and 2026, screening of titles and abstracts to eliminate duplicate and irrelevant studies, eligibility assessment through full-text review based on predetermined inclusion and exclusion criteria, data extraction and validation for qualitative synthesis, and finally of 21 papers for analysis result, conclusion, limitation of research, research gap and novelty. The findings demonstrate that storage efficiency, verification speed, encryption diversity, fraud prevention and identity standards. The conclusion of this study is that a collaborative framework integrating blockchain with cryptographic techniques for the security and verification of digital education certificates, with a robust process, can create a robust and adaptive system against certificate forgery. This study provides conceptual and practical knowledge for developing a more comprehensive education certificate security framework.
