Kejahatan konvensial yang terekam kamera CCTV (Closed Circuit Televison) semakin banyak ditemukan di masyarakat, setiap pelaku kejahatan yang terbukti melakukan tindak pidana tertentu akan dihukum sesuai dengan peraturan perundang-undangan. Kamera CCTV memiliki peran penting dalam keamanan, banyak diantaranya hasil tangkapan rekaman kamera CCTV dijadikan sebagai alat bukti digital. Tantangannya adalah bagaimana teknik yang diperlukan untuk penanganan khusus investigasi digital forensik dalam mencari bukti ditgital rekaman kamera CCTV menggunakan metode live forensik, yaitu ketika barang bukti dalam keadan aktif berdasarkan pedoman SNI 27037:2014 sesuai acuan kerangka kerja Common Phases of Computer Forensics Investigation Models untuk di implementasikan ke dalam dokumen Chain of Custody. Hasil penelitian ini berupa hasil analisis video rekaman kamera CCTV tentang karakteristik bukti digital dan informasi metadata yang digunakan untuk memberikan penjelasan komprehensif secara terstruktur serta acuan pengelolaan informasi data yang didapat dari hasil investigasi digital forensik yang dapat dipertanggungjawabkan dalam persidangan. Kata kunci: Bukti Digital, Live Forensik, Metadata, Kamera CCTV, Chain of Custody. Abstract Conventional crimes that are recorded on CCTV (Closed Circuit Television) cameras are increasingly being found in society, every crime that commits certain crimes will be in accordance with statutory regulations. CCTV cameras have an important role in security, many of which are recorded by CCTV cameras used as digital evidence. The challenge is how the techniques required for special handling, digital forensics in searching for digital evidence of CCTV camera footage using the live forensic method, namely when the evidence is in an active state based on the latest SNI 27037: 2014 according to the framework reference Common Phases of Computer Forensics Investigation Models for in implement it into the Chain of Custody document. These results of this research are in the form of analysis of CCTV camera video recordings about the characteristics of digital evidence and metadata information used to provide a structured comprehensive explanation and reference data management information obtained from the results of digital forensic investigations that can be accounted for in court. Keywords: Digital Evidence, Live Forensic, Metadata, CCTV Camera, Chain of Custady.
In general, system security has become a crucial element in the digital aspect. Technically, evaluating the system there are aspects, one of which is by conducting a security assessment. Specifically, each system that will be evaluated is the essence of vulnerability search. The information security assessment is a form of awareness regarding cyberattacks that always increases from year to year. The assessment process can be carried out by an internal team and/or external auditor. The stages of evaluation by internal teams are certainly different from those of external parties. External auditors in conducting assessments need to learn or get as much information as possible related to the target, which in this case is in the form of a subdomain. Therefore, we need applications that support effective and efficient Information Gathering to assist in analysis and reporting. There are still many Information Gathering applications that do not include reporting and data validation systems. In this study, it is proposed to develop applications to support the Information Gathering stage which makes it easier for Cyber Security researchers/analysts.
Kejahatan konvensional yang terekam kamera CCTV (Closed Circuit Televison) semakin meningkat, setiap pelaku kejahatan yang terbukti melakukan tindak pidana tertentu akan dihukum sesuai dengan peraturan perundang-undangan. Permasalahannya, adalah bagaimana sebuah kasus yang terekam pada kamera CCTV dapat dijadikan sebagai alat bukti digital. Bukti digital berkaitan erat dalam memastikan keamanan, privasi dan integritas data saat mengikuti tahapan proses identifikasi digital forensik. Tahap identifikasi menggunakan metode NIST (National Institute of Standarts Technolog) digunakan untuk investigasi dalam mencari informasi terkait metadata pada rekaman kamera CCTV agar dapat memberikan informasi terstruktur, menggambarkan serta mengolah sebuah informasi yang didapat dari sumber investigasi digital forensik dapat di implementasikan kedalam dokumen Chain of Custody yang bertujuan untuk dapat digunakan sebagai alat bukti digital yang sah dalam pengadilan
Accessing or theft of public network information is very vulnerable to data transmission on public networks, this has an impact on the loss of those who have the information. In the digital forensic world, securing data is a technique for anti-forensic that aims to keep data safe. One way to secure information when sending is done is to encrypt the data and information. Encryption techniques play an important role in cryptography to hide text or messages into an image as a public key. The use of images as key objects is very effective for data security and the information cannot be read or unknown by unauthorized persons. In this case the asymmetric key cryptographic technique uses images and the single layer perceptron, asymmetric cryptography through the encryption and description process can produce data and information security keys that are difficult to guess. The use of keys is done by extracting image features using the GLCM (grey level co-occurrence matrix) to produce random symbols perfectly through the training process using a single layer perceptron encryption asymmetry key and description that can be accounted for integrity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
