Let f ( x ) be a function on x. The Wiener-type indices, denoted by W f ( G ), is defined as W f = W f ( G ) = ∑ { u , v } ⊆ V ( G ) f ( d G ( u , v ) ). In this note, we use Wiener-type indices to give some sufficient conditions for lower bounds ...

The security of online assessments is a major concern due to widespread cheating. One common form of cheating is impersonation, where students invite unauthorized persons to take assessments on their behalf. Several techniques exist to handle ...

Hypervisor, the core software in cloud computing, is susceptible to malicious intrusions, potentially jeopardizing overall platform security. Physical hosts within the cloud computing environment constantly face persistent attacks, and not all ...

Wireless Mesh Network (WMN) has become the most favorable choice among various networking options due to its distributed nature. It offers continuous Internet services, in comparison with other conventional networks, through a self-healing and ...

The widespread use of digital platforms, prioritising content based on engagement metrics and rewarding content creators accordingly, has contributed to the proliferation of disinformation and its far-reaching social and political impact. In addition, ...

The management of electronic health records in modern healthcare systems is crucial. To ensure confidentiality, integrity, and accessibility, regulations such as GDPR and HIPAA have been established in several countries. Various research studies have ...

Non-Fungible Tokens (or, for short, NFT) establish the ownership and the authenticity of digital assets. Regardless the high security levels provided by blockchain, are not excluded the cases where the ownership of a digital object may be claimed ...

A blind semi-fragile watermarking scheme for disinformation detection in online social media (OSM) is presented. The proposed scheme can be used for both images and videos. We also propose a blockchain-based framework for traceability and propagation ...

Additive Manufacturing (AM) was originally invented to reduce the cost of the prototyping process. Over time, the technology evolved to be faster, more accurate, and affordable. These factors, in addition to the potential use of AM in parts ...

The lack of data security and the hazardous nature of the Internet of Vehicles (IoV), in the absence of networking settings, have prevented the openness and self-organization of the vehicle networks of IoV cars. The lapses originating in the areas ...

Cloud storage auditing allows the data owner/verifier to check whether the cloud correctly stores data owners' data. In cloud storage auditing scenario, data ownership transfer is a non-negligible problem. However, the existing cloud storage ...

In the field of healthcare, the emerging concept of the Internet of Medical Things (IoMT) plays a crucial role in enhancing the efficiency of medical services and introducing innovative solutions. Traditional healthcare services are no longer ...

Cloud computing is a new paradigm in this new cyber era. Nowadays, most organizations are showing more reliability in this environment. The increasing reliability of the Cloud also makes it vulnerable. As vulnerability increases, there will be a ...

Appropriate trust is an important component of the interaction between people and AI systems, in that “inappropriate” trust can cause disuse, misuse, or abuse of AI. To foster appropriate trust in AI, we need to understand how AI systems can elicit ...

This research work explores the growing role of IoT devices in daily life and the increasing demand for secure data transmission in different sectors like healthcare, military, etc. Moreover, this study focuses on the recent advancements in ...

In this paper we study the integrity of grid-graphs P m □ P n. We prove that if n 1 / 2 + α < m ≤ n, α > 0, then the integrity of P m □ P n is asymptotically equal to ( 2 2 / 3 + 2 − 1 / 3 ) ( m n ) 2 / 3.

Ensuring the integrity and authenticity of images is a paramount task in the digital multimedia context. The emergence of digital technologies necessitates the development of robust techniques to safeguard medical images against tampering or ...

The Internet of Things (IoT) is the communications technology where, physical objects, which are basically not designed for connection, will be able to connect, create, receive and exchange collected data permanently and transparently. Many IoT ...

Precise point positioning (PPP) and real-time kinematic techniques are interesting in several sectors, especially for autonomous applications. These users have high accuracy needs coupled with stringent requirements on continuity, availability, ...

Let G be a finite simple graph with vertex set V ( G ). We define the Wiener index of G as W ( G ) = ∑ { u , v } ∈ V ( G ) d ( u , v ), where d ( u , v ) is the distance between u and v. This topological index was defined by Wiener in ...
