Forensic Analysis of Unmanned Aerial Vehicle to Obtain GPS Log Data as Digital Evidence Septyan Eka Prastya Departement of Informatics Universitas Islam Indonesia Yogyakarta, Indonesia septyan_iyas@rocketmail.com Imam Riadi Department of Information System Ahmad Dahlan University Yogyakarta, Indonesia imam.riadi@is.uad.ac.id Ahmad Luthfi Departement of Informatics Universitas Islam Indonesia Yogyakarta, Indonesia Ahmad.luthfi@uii.ac.id Abstract— In recent years, the use of drones by civilians is increasing rapidly by the presentation of total sales continued to increase rapidly every year. With the increasing possibility of Unmanned Aerial Vehicle (UAV) abuse, crime in the use of UAVs to be larger. Through forensic analysis of data using static forensic and live forensic to obtain data that allows it to be used as digital evidence. To dig up information that could be used as digital evidence in the UAV and controllers, as well as to know the characteristics of digital evidence on a UAV. The results showed that digital evidence on a UAV, the smartphone is used as a controller UAV has a very important role in the investigation. The findings in aircraft has a percentage of 50% and a camera memory card with 16.6%. DJI Phantom 3 Advanced GPS coordinates always store data in flight LOG; the data is always stored even when the flight mode is used does not use GPS signals to stability. Due to DJI Phantom 3 Advanced always use GPS on flights, file, image or video captured by the camera has the best GPS location coordinates to the metadata therein.

This is now the most widely used in the military and those fans the hobby of photography/videography. In recent years, the use of drones by civilians increased rapidly, until it is mentioned by the UK House of Lords that 2014 is the "Year of the drones" [1]. Forbes magazine in 2015 wrote on its Web site sales distribution one trademark holder drones from its inception to the present. At the beginning of sales in 2009 to 2010, the presentation of the annual income more than 50% of overall sales are in North American. Moreover, in 2011 the total annual sales presentation to increase up to 280%, while sales in the North American presentation of only about 30% of total sales. Presentation of total sales continued to increase rapidly every year, the sale of drones in 2020 is expected to touch $ 2.28 Billion [2]. Drone works with two parts; the first is the drone itself and a controller that functions to control the drones. In some types of drones, there is already no longer requires a controller for controlling the aircraft. This type of drone using GPS transmitters installed on the users, so when this is enabled drones, aircraft will automatically follow any direction from people who used the transmitter. Drone with works like this has many sensors on the aircraft, which is useful to keep the drones remain safe from the surrounding environment when flying follow users. Digital evidence that can be taken from the body of drones and the controller is the ID of the drone itself, the location where the drone ever flew, image or video is taken when drones were flown, log update the software used. While the controller can be found in the form of digital evidence storage of images or videos taken using drones, log the location of the use of drones, the software used to control the drone, the ID of the drones are connected. Realm of this study is to gather information and conducts an analysis of digital evidence contained on drones along its controller by using static forensic and lives forensic with efforts to help complete the information on the forensic activity that uses GPS on the drone. II. RELATED WORK Several studies have been done on a UAV. Research about the small quadcopter demonstrates the utility of UAVs to safely and accurately mapped physical and biological characteristics of the unique habitat[3]. Then research explores the basics of the estimates and the flight controls for small winged UAV remains that covers common sensor and sensor configuration used small UAVs to be estimated[4]. Other studies have also been conducted, which is about the theory and practice of spoofing of Unmanned Aerial Vehicle (UAV) is captured and controlled by using a signal Global Positioning System (GPS)[5]. In 2014 conducted research to discover forensic methods in the search for artifacts that may be used for digital evidence on the device Garmin and Tom Tom satnav. The results obtained in the form of the acquisition method and the analysis and comparison of data obtained in the navigation system Garmin and Tom Tom[6]. Similar research is also done by exploration of digital evidence on Android Smartphone with through several stages. Results obtained in the form of technical image acquisition and analysis of digital evidence GPS on Android Smartphone, the application framework for the investigation, and provides several options framework that can be used[7]. Another study conducted on GPS data are based on a study reported in the relevant publication and focuses on variable directly to a GPS device such as clouds, weather, obstructions, International Journal of Computer Science and Information Security (IJCSIS), Vol. 15, No. 3, March 2017 280 https://sites.google.com/site/ijcsis/ ISSN 1947-5500
