Abstract:Uspešnost preiskav digitalnih podatkov in pridobivanje dokazov sta lahko v veliki meri odvisna od natančno opravljene hišne preiskave in pridobljenih informacij. Strokovno in natančno opravljena hišna preiskava lahko storilcu prepreči izvajanje določenih metod protiforenzike, kot so na primer destruktivna dejanja. Z morebiti najdenimi zapisi gesel na listih ali analizo med hišno preiskavo zavarovanega spomina delovnega pomnilnika računalnika je mogoče v nadaljnji fazi preiskave podatkov elektronskih naprav uspešno dešifrirati digitalne podatke, jih preiskati in zavarovati obremenilne digitalne dokaze. V diplomskem delu sta na pregleden način predstavljena pojma digitalni dokaz in posnetki spolnih zlorab otrok. Nadalje je opisan pojem digitalna forenzika vključno z načeli digitalne forenzike in metodologijo digitalne preiskave. Opredeljen je tudi pojem digitalna protiforenzika in predstavljene različne protiforenzične tehnike, s katerimi storilci poskušajo otežiti ali onemogočiti forenzične preiskave, kadar poskušajo prikriti posedovanje digitalnih posnetkov spolnih zlorab otrok. Nadalje je opisana taktika, tehnika in metodika izvedbe hišne preiskave. Poudarjena je pomembnost načrtovanja izvedbe hišne preiskave in opisane določene posebnosti pridobivanja digitalnih dokazov, ki se razlikujejo od opravljanja klasičnih hišnih preiskav, kjer se iščejo predmeti v fizični obliki. Na koncu dela sta opredeljena postopka zavarovanje in preiskava elektronske naprave ter predstavljeni ukrepi za zmanjševanje vpliva digitalne protiforenzike na forenzične preiskave.

Title:The impact of anti-forensics on investigations of digital child abuse material
Abstract:The thesis presents a notion of digital evidence and child sexual abuse material in a transparent way. Furthermore, it describes the concept of digital forensics, including the principles and methodology of digital forensic examinations. Digital forensics principles and methodology of the examination serve as a basis for forensically sound and legal procedures of digital forensics. The term anti-forensics is defined and various anti-forensics techniques are presented that are used by offenders to impede or try to make investigations impossible, when trying to conceal the possession of child sexual abuse material. Success of an investigation of digital data and acquisition of digital evidence greatly depends on how carefully a house search was conducted and on acquired information during the criminal investigation. Therefore the thesis also describes a tactics, techniques and realization of a house search. The importance of planning and execution of a house search is emphasized and certain particularities in digital evidence acquisition that differ from a classic search for evidence on a house search are described. Professionally and precisely conducted house search can prevent the offender from executing certain anti-forensics measures like destructive processes. Certain passwords or deciphering keys may be identified on notes or later from analysis of computer’s RAM that could result in successful identification, acquisition and examination of incriminating evidence within encrypted data. Standard operating procedures for acquisition and examination of electronic devices are defined at the end, together with some counter-measures for reducing the impact of anti-forensics on forensic examinations.
