Mobile phone (smartphone) is a source of criminalistics information

Abstract

This article discusses a mobile phone (smartphone) as a source of forensic information. To understand the technology of wireless communications, a brief overview of the basic principles of the functioning of a telecommunication network is made. Based on the accumulated experience and scientific developments, typical traces are found that are on the surface of the device and its elements; stored in the memory blocks of the hardware-software complex of the device, as well as the inserted SIM-card and memory card; hosted on servers (in "cloud" information storage services), which can be accessed by authorization using a smartphone. The possibilities and directions of a possible expert and non-expert identification and study of the described traces are considered. The features of the current state of forensic support tactics for examining a mobile phone are highlighted, its problems are identified and proposals for their solution are formulated. The possibilities of national databases are analyzed, which contain the relationship between the personal data of the user, IMEI of his mobile phone (smartphone), numbers and contacts of the phone book, and more. The names and functional purpose of computer programs for searching and analyzing data, including remote data from mobile devices, are indicated.
