The European General Data Protection Regulation (GDPR), which went into effect in May 2018, brought new rules for the processing of personal data that affect many business models, including online advertising. Mechanism, in the form of an algorithm and a set of results and conclusions Research gaps, and materials and methods we, thus, presented and implemented a cloud security Furthermore, to aidĬloud security in healthcare systems, we presented the motivation, objectives, related works, major Secure data storage in cloud-based healthcare systems, with a load factor of 0.9. The simulation work show that our proposed security mechanism provides an effective solution for

Linux 6 we executed five experiments, and the average of the results has been taken. We used Hadoop version 0.20.3, and the platform was Red Hat Enterprise Improves their respective throughputs by 0.9× to 15.5×, 1.3× to 1.6×, and 1.3× to 2.5×, whenĬompared to cuckoo filters. The Morton filter improves security it supports insertions, deletions, and lookups operations and A Morton filter is anĪpproximate set membership data structure (ASMDS) that proves many improvements to otherĭata structures, such as cuckoo, bloom, semi-sorting cuckoo, and rank and select quotient filters. Such as fragile watermark, least significant bit replacement watermarking, class reliability factor,Īnd Morton filters included in the formation of the security mechanism. The proposed solution enhances security with methods In this research, a novel cloud security mechanism is introduced, which supersedes Most of the existing studies focus on cuckoo and bloom filters, without considering Structures and watermarking techniques were used in the cloud-based healthcare systems to secure Systems is to provide security and privacy to electronic health records. One of the most challenging tasks in cloud-based healthcare If these data areĪcquired by a malicious user, it will not only cause the pilferage of the patient’s personal data butĪlso affect the diagnosis and treatment. Last but not least, we analyze the security of the four most important Chromium-based browsers: Brave, Chrome, Microsoft Edge, and Opera, concluding that all of them suffer from the same security pitfall.Įlectronic health records contain the patient’s sensitive information.

This paper demonstrates that it is possible to perform browser hijacking, browser extension fingerprinting, and remote code execution attacks as well as silent browser extensions (un)installation by coding a platform-independent proof-of-concept changeware that exploits the HMAC, allowing for free modification of the Secure Preferences file. Concretely, Google introduced a security mechanism based on a cryptographic algorithm named Hash-based Message Authentication Code (HMAC) to avoid users and applications other than the browser modifying the Secure Preferences file. This capability was as simple as adding/removing some lines from a plain text file called Secure Preferences file automatically created by Chromium the first time it was launched.

Google disabled years ago the possibility to freely modify some internal configuration parameters, so options like silently (un)install browser extensions, changing the home page or the search engine were banned.
