Digital cryptocurrencies especially privacy-oriented cryptocurrencies over the past years have experienced significant growth in terms of usage. The increased usage of privacy-oriented cryptocurrencies due to the offered privacy and anonymity, allows a cybercriminal to commit illegal transactions that are harder to trace back than Bitcoin. In this paper, we provide a forensic overview of the privacyoriented cryptocurrencies Monero, Verge, Dash, and Zcash. We analyse forensics experiments with these cryptocurrencies and make some assumptions and conclusions related to the analysed experiments.

In this paper, a novel patent-pending approach based on optical detection will be described. Various functionalized nanofiber materials have been used to demonstrate feasibility of realization of miniature sensors of biomedical and chemical values (enzymes reactions, metal ions content, etc.). Compactness and sensitivity of the sensors are significantly enhanced through original hybrid fiber-optic/nanofiber design. The potential of the new detection principle for security applications (forensic, seal intrusion, etc.) will be discussed.
