Kaliurang KM 14,5 Yogyakarta, 55584 ABSTRACT Cybercrime on smartphone users increasing every year. Unfortunately, the crime rate is not matched with user awareness about security in cybercrime activity so that similar crimes often occur back on the user's smartphone. Based on the literature study and review of related research beforehand. The main component of the research can not be separated from some things, such as user characteristics, awareness of smartphone users against cybercrime activity and the type of data that the target of the attack. This study is one of the solutions to measure the awareness of smartphone users against cybercrime activity and to produce research schemes that have better value. With the research is expected to overcome the problem of cybercrime is happening on smartphone users which caused a lack of awareness of smartphone users against cybercrime activity. Keywords Digital Forensics, Smartphone, Security, Cybercrime 1. INTRODUCTION The development of communication technology has been very rapidly penetrated into all layers, so in some aspects have changed the pattern of community life. Results of development of communication technology is the emergence of the smartphone, which is a very smart thing to use a variety of ways by the users. Smartphone equipped with a wide range of applications for the purposes of chat, email, phone, social media, and other applications [1]. In 2014, the number of Internet users, or Internet users in Indonesia is estimated to reach 71 million users. Of that amount, 41 million of whom access via smartphone and 70 million of them accessing social media such as Facebook, Twitter, Path, Instagram, LinkedIn, Google+. In addition, four out of ten people said user of social networking sites have or know of an attack on the social networking site. The data also shows, one in six people admitted they never compromised accounts, another 10% said never fooled by fraud techniques on the Internet or mengclick links that appear on their social networking site pages [2]. Indonesian Computer Emergency Response Team (IDCERT) said in 2013 in less than 24 hours of action cybercrime has increased two-fold from 30 535 at 11 June to 71,000 on June 12, where at least there are about 6 thousand IP addresses that allegedly affiliated Indonesia with a particular application so that it can result in a variety of things (information leakage, data theft, etc.) [3]. An estimated 556 million people each year become victims of Internet crimes, in addition to the estimated loss reached 21 billion dollars in result by malware, viruses, spam, hacking and fraud or theft [4]. The results of various research above, it appears that the crime at smartphone users is increasing. Unfortunately, awareness of users of smartphones on network security in cybercrime activities is still lacking, so that similar crimes often occur back on the user's smartphone. With no finding of previous studies regarding awareness of smartphone users against cybercrime activities, so this research is very important and useful for a variety of institutions and individuals. 2. LITERATURE REVIEW 2.1 Digital Forensics Digital forensics/computer forensics is a derivative disciplines of computer security that discusses the findings of digital evidence after an event occurs. Computer forensics activity itself is a process to identify, preserve, analyze, and use digital evidence under applicable law. Digital forensics is the application of science and computer technology to carry out the examination and analysis of electronic evidence and digital evidence in view of its association with crime [5]. According to the EC Council [6], digital forensics is a series of models of techniques and procedures to obtain evidence of computer equipment, various storage media and digital media that can be presented in court with a format that can be understood and have meaning. Sedabgkan according to [7]. Digital forensics is the application of science and computer technology to carry out the examination and analysis of electronic evidence and digital evidence in view of its association with crime. 2.2 Cybercrime Cybercrime is against the law that utilize computer technology based on the sophistication of Internet technology development. Where the Internet is a network of computers connected to each other through communication media. Cybercrime (cybercrime) is a term that refers to criminal activity with a computer or computer network into a tool, target or scene of the crime. Including into cybercrimes include online auction fraud, check forgery, credit card fraud/carding, confidence fraud, identity fraud, child pornography, etc. [8]. According to Petrus Reinhard Golose, the quotation Putra and Evan [9]. the types of cybercrime can be described as follows. a. Entering network/computer system illegally, without permission or without the knowledge of the owner of the network / system. b. Transmits data or disseminate information about something that is untrue, unethical, and may violate the law or disturbing public order. c. Falsifying the data contained in the network as well as action to enter data that can benefit the perpetrator or
