Data privacy and integrity maintenance becomes more difficult as cloud computing expands. Such complex and advanced cyberattacks need for stronger and better defenses than traditional security measures can offer. A research paper that combines blockchain technology with quantum cryptography to improve data security in the cloud paradigm. In addition, aspects of blockchain itself – its distributed and cryptographically verified ledger – offer the possibility of transparency and immutability of the life of the data. Excited by that?

Abstract:

Blockchain naturally fits multiple industry sectors due its characteristics of decentralization, enhanced security, tamper-proof, improved traceability and transparency. However, there is a significant concern of blockchain’s performance, since blockchain trades off its performance for a completely distributed feature, which enhances its security. In this paper, we investigate the state-of-the-art progress of blockchain, mainly from a performance and security perspective. We extracted 42 primary papers from major scientific databases and 34 online technical articles. The objective is to unders

Abstract:

Ensuring the integrity of evidence is paramount within the realm of digital forensics. The preservation of evidence gathered at a crime scene is essential for concluding investigations and delivering justice to those involved. Hence, it is imperative to safeguard this evidence from any form of tampering. The process that upholds the reliability of evidence is known as the "chain of custody." Failure to maintain the chain of custody can render the evidence inadmissible in court, potentially resulting in the dismissal of the case. To address these challenges and promote an eco-friendly approach,
