Blockchain meets lightweight cryptography

February 10, 2023 by Safiullah Khan

The Internet of Things (IoT) typically comprises sensors that have inadequate computational resources. On the contrary, blockchain technology is thought to be expensive in terms of resource consumption due to the consensus procedures involved. As a result, the application of blockchain to the IoT environment is a challenging task. The most appropriate solution lies in replacing … [Read more...] about Blockchain meets lightweight cryptography

Digital watermarking—A tutorial

June 28, 2022 by Rajkumar Ramasamy; Vasuki Arumugam

Digital watermarking is a technique in which secret information is embedded inside a host signal, which may be an audio, video, or image signal. Watermarking is also defined as a branch of information hiding that is used to hide proprietary information in digital media. Digital watermarking may be used for authentication, integrity, or information security. In this article, we … [Read more...] about Digital watermarking—A tutorial

Privacy implications of facial recognition technology

Facial recognition technology (FRT) has experienced enormous growth and rapid deployment across different sectors of the society in recent years, mostly motivated by safety, security, and commercial applications. However, major privacy questions arise around this technology, and regulators are still working to provide clear set of rules governing its use. This paper focuses on privacy implications of FRT usage. Specifically, we first present the definition of FRT, followed by an analysis of the vulnerability and risks that can potentially arise and how they might be concerning in such context. Finally, we discuss efforts needed to mitigate privacy concerns related to FRT, from both technical and regulatory perspectives.
