Many of the devices in the IoT group process personal information or information enabling profiling or revealing the identity of natural persons. Naturally, the question of the security of this information and compliance with the legal requirements for the protection of the personal data of natural persons and their inviolability arises. The study defined the main issues related to the protection of personal data, identified threats and risks to the security and privacy of information processed by IoT devices.

Electronic voting (e-voting) offers many advantages compared to traditional types of voting. Today there are many e-voting schemes and systems, which allow their use for various purposes. Because of its fundamental importance for democratic societies, e-voting is subject to high legal standards, in particular security requirements for the voting method. It is hard to create a system or a protocol fulfilling all security requirements. Designing effective e-voting systems is challenging because these aspects often conflict with each other. For example, one of such challenges is trying to ensure identification and keep votes private while still being able to verify them. There are quite a few cryptographic schemes which fulfill wide requirements for electronic elections, but they use sophisticated cryptographic tools that make them hard to implement and require expertise in various fields. In this paper we suggest a new approach that ensures this requirements without complex cryptographic methods, using only face recognition, properties of entropy, hash functions and steganography.

Virtual Private Networks (VPN) enable usage of the public Internet infrastructure to build se-cure and reliable connections providing functionally of private corporate IT networks. Back in 90s VPN were created to mainly allow access to corporate resources for employees who work remotely and/or travel. Today, VPN can be used to gain access to geographically isolated and highly protected Internet resources like websites, interactive platforms and more. Such VPN are good for protecting Internet users’ privacy and enhance their security especially when using public free Wi-Fi networks. Indeed, now VPN are used more and more and gain popularity for exactly those reasons – provide almost universal access and protect privacy of millions Internet users. This paper reviews building blocks and procedure to build our own VPN. This way power users are in full control of their privacy and security when using public Internet infrastructure while also gain access to otherwise restricted online resources.
