Introduction
Criminalistics and digital technology are terms that today play a fundamental role in improving criminal investigation. In the digital age, criminalistics has been transformed by integrating advanced technological tools, significantly optimizing the analysis and resolution of crimes. From the identification of digital evidence to its incorporation into legal procedures, digital technology – whose application has deepened in innovative fields such as those explored in Engineering – has revolutionized the investigative process, opening the door to increasingly precise and effective digital forensic analysis methods.
Context and Importance of Criminalistics in the Digital Age
Criminalistics is the scientific discipline responsible for the study and analysis of clues and evidence to reconstruct criminal acts. Traditionally based on the collection of physical evidence and testimonies, it has evolved significantly with the advent of digital technology. Currently, it is estimated that between 80% and 90% of criminal cases involve digital evidence, which underscores the importance of incorporating technological tools into every investigation.
Digital technology has allowed a radical change in how evidence is collected and analyzed, ranging from the identification of traces on electronic devices to the analysis of cloud records, ensuring a complete interpretation of the crime scene.
Keywords: criminalistics, digital technology, digital evidence.
Digital Technology Applied to Criminal Investigation
The integration of digital systems into criminalistics has transformed traditional investigative methods. The following stages in the process stand out:
- Identification: Objectives are determined, and sources of digital evidence are identified, including computers, mobile phones, network devices, and servers.
- Acquisition/Collection: Specialized software is used to obtain an exact forensic copy of the data, preserving it without alteration.
- Preservation: Every step of the chain of custody is meticulously documented to ensure the integrity and authenticity of the evidence.
- Analysis: Advanced digital forensic analysis tools – techniques typical of doctoral studies in technological areas – study the data to identify crucial patterns and connections.
- Documentation and Presentation: Results are systematized into detailed reports that can be presented in judicial proceedings.
This flow optimizes criminal investigation and establishes a clear and reliable process in the search for truth. Keywords: criminal investigation, digital evidence, digital forensic analysis.
