“…A popular option to get around this problem is a very simple one, you store the personal data off-chain and store the reference to this data, along with its hash and other metadata (like ownership status, timestamp, permissions…), on the Blockchain. This approach was implemented by El Khanboubi and Hanoune in [1] which makes the proposed model partially GDPR compliant since the data is not fully erased when requested and the ownership history can still be retrieved if there are other users owning the same file.…”

“…The model in question [1] uses several techniques and concepts that were aforementioned. The authors proposed the usage of a Blockchain for each file newly uploaded; before storing it in the file system, the file in question goes through a two-steps process as follow:…”

“…To remedy this issue we have decided to use asymmetric encryption to encrypt the metadata that will be stored in the new generated block. As described in [1], the CSP already holds the user's public key that is used during the authentication process, this way the user's identity as well as his files history of ownership will be preserved. To retrieve the data, the user first authenticate using his private key, the user should hold (in a local database on the client side) the number of every block that was mined in the Blockchain on his behalf by the CSP (knowing that users are not allowed to add new block to the Blockchain), this way when accessing a file, the user does not have to iterate over each block trying to decrypt one by one but instead he decrypts only the data that was encrypted using his private key.…”

“…In [1] El Khanboubi and Hanoune proposed a new framework based on Blockchain technology where de-duplication is made on the client side and the original file is chunked using a content-aware chunking algorithm in order to increase the probability to de-duplicate not only files in whole but even parts of files, the actual file (or chunks of the file) is stored in cloud storage while its references are stored in a Blockchain, the proposed structure of the Blockchain allow user having uploaded the same file to share only references without uploading the same file again, and if two files share one or more part of a file, only the missing parts are uploaded. This model improves significantly the amount of data stored, but knowing that Blockchain technology is immutable and doesn't allow deletion, this approach does not allow blocks deletion thus file deletion will leave an incoherent system, a corrupted data even.…”

Almost all Cloud Service Providers (CSP) takes a principled approach to the storage and deletion of Customer Data. Most of them have engineered their cloud platform to achieve a high degree of speed, availability, durability, and consistency. Their systems are designed to be optimized for these performance attributes and must be carefully balanced with the necessity to achieve accurate and timely data deletion.many researchers have turn their focus toward data storage and how it will be a challenging task for CSPs in term of storage capacity, data management and security, a considerable number of papers has been published containing new models and technique that will allow data De-duplication in a shared environment but few of them have discussed data deletion.In this paper we will be discussing a new approach that will allow a smart deletion of data stored in the file system as well as its reference in the Blockchain since, by its nature, Blockchains does not allow deletion without violating the Blockchain’s consistency, a preexisting de-duplication system will be our base platform on which we will be working to achieve an accurate and secure data deletion using Blockchain technology while preserving its consistency.

To favor emergency vehicles, promote collective modes of transport in Moroccan cities, we propose in this paper a control system to manage traffic at signalized intersections with priority links in urban settings. This system combines multi-agent technology and fuzzy logic to regulate traffic flows. The traffic system flow is divided into two types of vehicles; priority and regular vehicles. The regular vehicles can use only the regular links, while the priority vehicles may use both priority and the regular links. This approach aims to favor emergency vehicles and promote collective modes of transport, it acts on the traffic light phases length and order to control all traffic flows. We proposed a decentralized system of regulation based on real-time monitoring to develop a local inter-section state, and intelligent coordination between neighboring intersections to build an overview of the traffic state. The regulation and prioritization decisions are made through cooperation, communication, and coordination between different agents. The performance of the proposed system is investigated and instantiated in ANYLOGIC simulator, using a section of the Marrakesh road network that contains priority links. The results indicate that the designed system can significantly develop the efficiency of the traffic regulation system.

[Context] The goal of security is to protect digital assets, devices, and services from being disrupted, exploited or stolen by unauthorized users. It is also about having reliable information available at the right time. [Motivation] Since the inception in 2009 of the first cryptocurrency, few studies have been undertaken to analyze and review the state-of-the-art research and current developments with respect to the security of cryptocurrencies. [Purpose] We aim to provide both theoretical and empirical insights into the security landscape, in particular focusing on both technical solutions and human-related facets. [Methodology] We used an integrative review which could help in building science and scholarly research, the basis for conceptual and empirical models. [Results] Successful defense against cyberattacks depends on technical measures on the one hand, as well as on self-education and training with the aim to develop competence, knowledge, skills and social abilities, on the other. [Contribution] Our findings provide a comprehensive review for the major achievements and developments of the recent progress on the security of cryptocurrencies. [Future research] Since there is increasing interest in adoption of the current solutions within the central bank digital currencies, the future research should explore the development and inception of effective measures against social engineering attacks, which still remain the main concern.
