Forensic Detection of Synthetic Media: Is Deepfake Audio and Video Evidence Still Reliable?

The rapid maturation of generative artificial intelligence has made the production of synthetic audio, images and video (deepfakes) routine. This has undermined the long-held trust in audiovisual records and created an obligation to test technically the authenticity of every multimedia item submitted in a forensic process.

The Forensic Evidentiary Value of End-to-End Encrypted Messaging: WhatsApp, Signal and Telegram

End-to-end encryption (E2EE) has become the standard in messaging applications and, while strengthening privacy, has largely rendered traditional interception ineffective. This has created a paradigm shift for digital forensics: evidence must now be obtained not from the communication channel but from its endpoints — devices and cloud backups.

Cryptocurrency and Blockchain Forensic Tracing: From Wallet to Perpetrator

The pseudonymity offered by crypto assets has made them a preferred instrument for money laundering, ransomware, fraud and sanctions evasion. Conversely, the public and immutable ledger structure of most blockchains creates a forensic traceability absent from traditional financial systems. This article examines the forensic tracing of crypto-asset transactions along three axes.

AI-Based Real-Time Image Processing and Face Recognition Systems

Face recognition technology is becoming ever more widespread in critical fields such as security systems, access control, smart city infrastructure and human-computer interaction. This study addresses comprehensively the theoretical foundations of deep-learning-based face recognition, end-to-end pipeline design, hardware and software optimisation strategies and real-time deployment architectures.

Applying LoRa and LoRaWAN Technology in Industrial Communication Systems

Industrial Internet of Things (IIoT) applications demand reliable, low-power, long-range wireless communication infrastructure. Developed to overcome the limited range and high energy consumption of conventional wireless technologies (Wi-Fi, Bluetooth, ZigBee), the LoRa modulation technique and the LoRaWAN protocol stack built on it have become the preferred choice in industrial communication in recent years.

Quantum Computers and Encryption — Preparing for Q-Day: From Shor's Algorithm to the NIST Post-Quantum Standards

Quantum computers pose an existential threat to the cryptographic infrastructure of the digital age. The algorithm Peter Shor developed in 1994 theoretically defines quantum circuits able to solve the factoring of large numbers — the mathematical foundation of today's RSA encryption — in polynomial time.

Artificial Intelligence and NLP: Natural Language Processing with Python from the Transformer to RAG Systems

Natural Language Processing (NLP) is one of the fastest-growing subfields of artificial intelligence. The 2017 paper "Attention Is All You Need" and the Transformer architecture created a paradigm shift; BERT (2018), GPT-3 (2020) and the Large Language Models that followed carried NLP from research laboratories into corporate production environments.

Anonymised Data from an ISO 27000 Perspective: Techniques, Standards, Re-Identification Risk and KVKK Compliance

As the data economy accelerates, the balance between protecting personal data and keeping valuable data sets usable for research, statistics and artificial intelligence is becoming an increasingly strategic issue. Anonymisation constitutes the principal technical mechanism for striking that balance.

ISO 27000 and Information Security Management Systems: Standards and Practice

Information stands out as the most valuable asset of today's digital economy, and the rapid rise in cyber threats and data breaches is forcing organisations to treat information security as a strategic management issue. In this context the ISO/IEC 27000 family of standards, and its certifiable core ISO/IEC 27001, have become the common language of information security management worldwide.
