Abstract :In the field of forensic informatics, digital data related to criminal and forensic investigations are collected, analysed, preserved and presented. Hacking, digital data recovery, data analysis, data analysis, data analysis, digital document analysis and analysis of data from mobile devices and other digital devices are included in the field of forensics. Using data collected from computers, mobile devices, hard disks, USB drives, digital cameras, cloud storage and other digital media, forensic experts are tasked with finding evidence. They also work on issues such as finding ways to protect against hackers and creating digital security measures. In a rapidly evolving digital world, the field of forensics is crucial for assisting criminal investigations and tracking the digital footprints of criminals. The guiding principles of forensic experts are legal compliance, accuracy, objectivity and security of evidence. During case analysis, law enforcement and prosecutors take photographs of the crime scene and evidence, after which the relevant report is written and the evidence file is created. The transparency and reliability of the procedure for the case in question is threatened by the vulnerability of this digitized and preserved content. Cyber-attacks that modify or destroy digital data result in the loss of relevant digital evidence. To prevent this problem and provide a solution, this paper compares the performance of a blockchain-based digital data storage application with a Tangle-based system. Photos of the incident environment and the incident report are combined and stored in the test model. The performance metrics of the system are rigorously measured. The study reveals that IOTA Tangle shows significant speed advantages (35 ms for 3KB images and 31 ms for 11KB images), especially in scenarios involving the storage of image data. In our analysis, Hyperledger Fabric performs commendably in character data processing, exhibiting lower response times (36 ms for 100 characters and 32 ms for 1000 characters) compared to IOTA Tangle.
