Abstract

When sending a message to a specific party and do not want the message to be known by other parties, it is important to avoid information leakage. However, the problem identified is that there is a lack of knowledge to detect audio Ste-ganography which requires technical methods that can read and view secret messages. One method that can be used in steganography is Masking and Filtering. Masking as a media marker on audio that can insert messages. Filtering gives value to the parts that have been given a mark.  This method is one that is often used because it is simple, fast in the data insertion process, and has a large enough storage capacity. The Masking and Filtering method is able to hide messages by inserting them into the audio Spectrogram as a storage medium. The filter is used to ensure that the hidden message is within the previously analyzed frequency range, thus making humans unable to clearly hear the additional audio that has been inserted which is the hidden message.  After the insertion is complete, the audio file is saved, and tests are performed to ensure that the audio quality is not compromised, and the hidden message remains undetected such as making modifications to the stego file to test the robustness and security of the hidden message. Based on research, steganography is difficult to detect by the naked eye, to retrieve messages that have been hidden, it can be done by displaying an audio Spectrogram that contains a secret message. How to see the hidden message using the Audacity application that can see sound waves. The result is that the message embedded in the audio is not damaged even though compression, cutting, and some of the processes carried out in the audio have been carried out.

Abstract

The recovery of deleted data is an important aspect of forensic digital investigations, especially in identifying relevant evidence. However, deletion techniques such as the Sdelete command implement the Department of Defense (DoD) 5220.22-M standard which can permanently delete so that the process of recovering digital evidence from storage media will be difficult, while deletion using Shift+Delete only removes file references without overwriting the data, thus allowing data recovery with file carving techniques. This study uses a static forensic method, where the data in the flash drive has been deleted and acquired using FTK Imager so as to produce an imaging file to maintain the integrity of the evidence. After that, the imaging file is processed using file carving tools. This study aims to compare the results of deleted recovery using the Sdelete command and the Shift + Delete key combination and assess based on the highest percentage of the results of three file carving tools, namely Autopsy, Axiom Magnet, and Photore. The results of the study show that files deleted using Sdelete cannot be recovered by the three tools, both in terms of artifact findings and the suitability of hash values, according to Microsoft's claims. In contrast, files that have been deleted using the Shift + Delete key combination can still be recovered with varying success. PhotoRec has the highest recovery rate (90%), followed by Autopsy (88%) and Axiom Magnet (60%). In terms of hash value suitability, PhotoRec reaches 80%, while Autopsy 76% and Axiom Magnet 50%. These findings confirm that Sdelete is effective in permanently deleting data, while the Shift + Delete combination still allows for recovery with varying success rates. The author hopes that this research can be a new knowledge for digital forensic investigators in terms of selecting the most suitable file carving tools for digital evidence recovery.
