The Balinese language which is used in daily life on the island of Bali has experienced a shift in usage so it needs to be preserved. In an effort to preserve the Balinese language and script, the Provincial Government issued Bali Governor Regulation Number 20 of 2013 and Regulation number 1 of 2018. I Made Suatjana submitted a proposal that the Balinese script be included in Unicode to make it easier to display Balinese script on digital media. Cokorda Rai Adi Pramartha developed keyboards or keyboards and an application called T@miang to facilitate typing Balinese characters on computer devices. Computer equipment is slowly becoming obsolete, replaced by mobile devices used by 53.03% of users in Indonesia, so it is necessary to build a Balinese script keyboard that can be used on mobile devices. PaTik Bali is built for mobile devices with Android operating system. PaTik Bali layout is adapted to T@miang keyboard layout. PaTik Bali version 1.0 only uses the Balinese script on each keyboard key. In version 2.0 each button on PaTik Bali has been added Latin letters because of the large number of entries on the Google Play page. Based on data recorded on the Google Play Console, there are 41,820 devices that have installed the Balinese Keyboard (PaTik Bali) application, 99.19% are from Indonesia. In general, the PaTik Bali application can be accepted in the community, this can be seen from the average rating given by users on Google Play which is 4.27 on a scale of 5. However, some users complain about the incorrect form of letters. The PaTik Bali application uses fonts that have been embedded in the Android operating system so that it can be used as a keyboard in other applications. This font still has enough problems. To fix this problem, it is necessary to develop the Balinese font then ask Google as an Android developer to enter the new font into the Android operating system.

Google’s Android is the most used Operating System in mobile devices but as its popularity has increased hackers have taken advantage of the momentum to plague Google Play (Android’s Application Store) with multipurpose Malware that is capable of stealing private information and give the hacker remote control of smartphone’s features in the worst cases. This work presents an innovative methodology that helps in the process of malware detection for Android Operating System, which addresses aforementioned problem from a different perspective that even popular Anti-Malware software has left aside. It is based on the analysis of a common characteristic to all different kinds of malware: the need of network communications, so the victim device can interact with the attacker. It is important to highlight that in order to improve the security level in Android, our methodology should be considered in the process of malware detection. As main characteristic, it does not need to install additional kernel modules or to root the Android device. And finally as additional characteristic, it is as simple as can be considered for non-experienced users.

This paper proposes a new forensic analysis methodology that combines processes, techniques, and tools for physical and logical data acquisition from mobile devices. The proposed methodology allows an overview of the use of the In-System Programming (ISP) technique with the usage of Combination Firmware, aligned with specific collection and analysis processes. The carried out experiments show that the proposed methodology is convenient and practical and provides new possibilities for data acquisition on devices that run the Android Operating System with advanced protection mechanisms. The methodology is also feasible in devices compatible with the usage of Joint Test Action Group (JTAG) techniques and which use Embedded Multimedia Card (eMMC) or Embedded Multi-Chip Package (eMCP) as main memory. The techniques included in the methodology are effective on encrypted devices, in which the JTAG and Chip-Off techniques prove to be ineffective, especially on those that have an unauthorized access protection mechanism enabled, such as lock screen password, blocked bootloader, and Factory Reset Protection (FRP) active. Studies also demonstrate that data preservation and integrity are maintained, which is critical to a digital forensic process.

The presence of smartphones in the classrooms have been the theme of big debates among those involved in educational spaces. It is undeniable that its inclusion in teaching and learning processes approaches the school to the world where the student is in and an important step to elaborate strategies which involves the smartphones use is to know the educational apps functionalities. In this context, this article is proposed to do a systematic mapping of free educational apps to the physics teaching, available at the Android operating system presented in most smartphones and available at Google Play Store. It was adopted as methodology a systematic mapping organized in four steps. At the first moment the research was made with the use of the word “Physics” and 250 apps were found, the second step was intended to select the apps with physics content in Portuguese, which brought the number of 42 apps. Following, the third step was intended to map the specific apps for the physics subjects, excluding those that present in their content several subjects or only exercises collection, finding, so, 25 apps. Lastly, in fourth step, it was made a description of the apps selected from step 3 with more than 10.000 downloads. What was noticed in the description is that practically none presents the contextualization of physical phenomena or simulations, they only highlight nature theoretical or mathematical descriptions.

Although many ways to communicate with someone, SMS is still one of the popular media to send a message to someone. Not unlike the others, the messages sent can be known by the third party either tapping or the investigation. Unencrypted SMS can be easily obtained from communication providers so that they may be misused. Since the communication devices have been using Android operating system, they are programmable. There is various script can be inserted to devices to protect the data. One of them is Vernam Cipher. This method offers how to protect personal messages sent via SMS easily. It converts the message into an encrypted message shortly before sent. At the moment there tapping on the outside, the information is not easily understood its contents. The message is entirely secure.

Abstract. The use of Augmented Reality (AR) technology is widespread in countless archaeological sites and a variety of applications. Archaeological excavations lead to archaeological finds, some of which are transported for preservation and then for exhibition in museums (jewelry, vases, etc.), while another part of them is documented in detail and remains in situ (eg building walls), roads, grave covers, etc.). However, after the registration of the archaeological finds, it is impossible to observe them. As part of our research project, we will develop for the first time AR methodology and procedures for the observation of covered archaeological finds on mobile devices (smart phones, tablets), which were registered after their documentation. AR technology in recent years has seen great growth in terms of implementation platforms and available software, as well as the tools developed to support it. These tools either make their appearance in the form of frameworks, extending the capabilities of an existing engine, or function as independent services. At the same time, progress has been made in the field of sensors of mobile devices, which makes the compatibility of hardware and software another issue to be researched. As part of the development of the above application for mobile devices, an evaluation is made of the most widespread AR Frameworks that support the Unity3d Game Engine and the compatibility / interoperability with the sensors of different categories of mobile devices. The frameworks were checked and evaluated for placement and tracking of the positions of the 3D covered objects. In this paper also, methodologies and techniques used in space detection and tracking are presented and evaluated.
