A comparative study of perceptual hashing algorithms: Application on fingerprint images
(University of Oum El Bouaghi, 2021-05-25) Hamadouche, Maamar; Zebbiche, Khalil; Guerroumi, Mohamed; Tebbi, Hanane; Zafoune, Youcef
Perceptual image hashing has been broadly used in the literature to authenticate images or to identify similar contents for image copy detection. It can be used to improve the security of fingerprint-based identification systems, especially to guarantee the authenticity of fingerprint images. In this paper, a comparative study of the most used techniques in the field of perceptual hashing is provided, aiming at evaluating their performance when applied to fingerprint images. The study includes five techniques, namely: A-Hash, D-Hash, P-Hash, WHash and SVD-Hash. The performance has been assessed in terms of perceptual robustness, discrimination capability and authentication characteristics, through extensive experiments. The obtained results are promising and show that overall both the A-Hash and P-Hash performed well when compared to other evaluated techniques.
A Survey on Identity-based Key Management Schemes in Mobile Ad hoc networks
(University of Oum El Bouaghi, 2021-05-25) Gasmi, Kenza; Bourouis, Abdelhabib; Benaboud, Rohallah
Mobile Ad hoc networks attract more attention over the years, but the security matter of this type of network makes it hard to achieve all of their advantages. Cryptographic key management is the cornerstone for building any robust network security solution. Identity-based cryptography is a promising solution that resists well the key escrow problem which is suitable for Mobile Ad hoc networks. In this paper, we give an overview of the most important identity-based encryption schemes proposed in the last decade; combined with other techniques to enhance it and provide better results for Mobile Ad hoc networks. Hence, we give a comparative analysis to highlight their advantages and weaknesses. This work gives insights into a recent research to point out its interesting features, take advantages of its strength, ovoid its weaknesses and to lay out the future directions in this area.
Accounting Education: a theoretical overview
(University of Oum El Bouaghi, 2021-05-10) Khalfallah, Zakarya
The main purpose of this paper is to highlight the Accounting Education as a real asset that must continually evolve in order to best prepare future professionals on accounting for the new requirements imposed by technology and globalization. To do this, a descriptive methodological approach has been deployed to present Accounting Education Standards (IESs), which are developed by the International Accounting Education Standards Board (IAESB). These standards are influencing Accounting Education and training worldwide. The goal of the IESs is to ensure that economic decision makers can rely on the competence of professional accountants regardless of the country where the accountants received their education and training. Two major lessons emerge from this study. On the one hand, that the organizational structure, globalization and technology impact the skills needs of the accountancy profession and, on the other hand, there is a gap between the training provided and the needs of the profession. تستهدف هذه الورقة البحثية تسليط الضوء على التعليم المحاسبي كأداة حقيقية يجب أن تتطور باستمرار من أجل إعداد أفضل المهنيين المحاسبين في المستقبل، وذلك بهدف الاستجابة للمتطلبات الجديدة التي تفرضها التكنولوجيا والعولمة؛ وقد اعتمدت الورقة البحثية في تحقيق أهدافها على المنهج الوصفي التحليلي من خلال تقديم والتي تم تطويرها من قبل مجلس معايير تعليم ،(IESs) معايير التعليم المحاسبي حيث تؤثر هذه المعايير على التعليم المحاسبي ، (IAESB) المحاسبة الدولي والتدريب في جميع أنحاء العالم، كما تهدف إلى ضمان أن صناع القرار الاقتصادي يمكنهم الاعتماد على كفاءة المحاسبين بغض النظر عن الدولة التي تلقوا فيها تعليمهم وتدريبهم.
Achieving the quality of accounting learning outcomes: an Algerian perspective
(University of Oum El Bouaghi, 2021-05-10) Rimouche, Kaoutar; Himrane, Mohammed
This paper aims to demonstrate the efforts made by the International Accounting Education Standards Board (IAESB) in achieving the quality of the accounting learning outcomes and to explore the reality of accounting education in Algerian. We based on the comparative method in order to compare between the content of universities' accounting programs and the International Accounting Education Standard (2). Considering that the accounting educational system in universities should emphasize serving students and ensure that they will be able to practice the accounting profession in the future, and that accounting education should seek to adapt to the trend of professional accounting development. We have concluded that there is almost a perfect match between what Algerian universities apply and what the International Federation of accountant’s committee approved, but the problem lies in achieving the learning outcomes with the required quality as stated in the IES2 تهدف هذه الورقة إلى إظهار الجهود التي يبذلها المجلس الدولي لمعايير تعليم المحاسبة (IAESB) في تحقيق جودة مخرجات تعلم المحاسبة واستكشاف واقع تعليم المحاسبة في الج ا زئر. حيث اعتمدنا على المنهج المقارن لمقارنة بي ن محتوى برامج المحاسبة بالجامعات ومعيار تعليم المحاسبة الدولي (2). مع الأخذ في الاعتبار أن النظام التعليمي المحاسبي في الجامعات يجب أن يركز على خدمة الط لب والتأكد من أنهم سيكونون قادرين على ممارسة مهنة المحاسبة في المستقبل، وأن التعليم المحاسبي يجب أن يسعى للتكيف مع اتجاه تطوير المحاسبة المهنية. لقد توصلنا إلى أن هناك تطابقًا تامًا تقريبًا بين ما تقدمه الجامعات الجزائرية وما أقرته لجنة المحاسبين الفيدرالية الدولية، لكن المشكلة تكمن في تحقيق مخرجات التعلم بالجودة المطلوبة كما هو مذكور في .IES2
Activité physique et sportive de l’enfant et de l’adolescent : Des croyances aux recommandations sanitaires
(Université d'Oum El Bouaghi, 2022-04-23) Noubli-Dih, Amal; Louli, Hassiba
On entend trop souvent circuler des idées fausses sur la pratique de l’activité physique et sportive et son impact sur la santé des pratiquants jeunes et moins jeunes. De ce fait, notre objectif est d’apporter quelques éclaircissements et recommandations afin de prévenir et d’éviter certains dangers. La pratique des activités physiques et sportives chez les jeunes doit intégrer une information pertinente sur la nature des pratiques à privilégier selon l’âge (petite enfance, puberté, adolescence), mais aussi sur les bonnes aptitudes physiques des enfants en combattant des croyances tenaces sur leurs prétendues fatigabilité et fragilité. A contrario, cette information ne doit pas occulter les risques physiques et psychologiques induits par l’investissement sportif trop élevé au regard des possibilités du jeune sportif. Too often we hear misconceptions circulating about the practice of physical activity and sport and its impact on the health of young and old. Therefore, our goal is to provide some clarifications and recommendations in order to prevent and avoid certain dangers. The practice of physical and sports activities among young people must include relevant information on the nature of the practices to be favored according to age (early childhood, puberty, adolescence), but also on the good physical abilities of children by combating stubborn beliefs about their alleged fatigue and fragility. Conversely, this information should not obscure the physical risks and psychological induced by the investment in sport that is too high compared to the possibilities of the young athlete.
An extended artificial bee colony with skyline operator for solving the QoS uncertainty-aware web service composition under interval QoS properties
(University of Oum El Bouaghi, 2021-05-25) Seghir, Fateh; Ghizlane, Khababa
In this paper, we provide an extended artificial bee colony (EABC) algorithm with skyline operator for solving the QoS uncertainty-aware web service composition (IQSC) problem, where the uncertain QoS properties have been expressed as intervals numbers. At first, we formulate the addressed problem as an interval constrained single-objective optimization model. Then we employ the skyline operator to reduce the search space of IQSC. Whereas, the EABC algorithm has been performed to solve IQSC in a reduced search space more effectively and efficiently. To validate the performance and efficiency of the proposed approach, we present the experimental comparisons to an existing skyline-based PSO algorithm on an interval extended version of the public QWS dataset.
An Improved Binary Particle Swarm Optimization of RFM’s for ALSAT2 Imagery
(University of Oum El Bouaghi, 2021-05-25) Mezouar , Oussama; Meskine, Fatiha; Boukerch, Issam
Rational function model (RFM) is commonly used in photogrammetric and remote sensing applications because it does not need sensor parameters. Therefore, the RFM terms or also rational polynomial coefficients (RPCs) have no physical significance but depends on many ground control points (GCPs) that make the model prone to the over parameterization problem. This paper proposes a new binary particle swarm optimization algorithm to surmount the issue of over parameterization and find the optimum combination of RPCs for the RFM by adding a new transfer function in binary PSO in order to increase the convergence speed and avoid the local minimum phenomenon. The results showed that the proposed method is compatible with different types of RFM, more stable, and gives higher accuracy than the traditional binary PSO.
Analyse de la strategie de repartition des entites Commerciales dans la ville d’annaba
(Université D’Oum el Bouaghi 2021-11-02)
La ville d’Annaba est la quatrièe ville d’Algéie situé àl’extrêe Nordestalgérien. Son caractère touristique, conjugué à son dynamisme économique et sa vitalité commerciale, lui confère un statut de territoire très attractif rayonnant sur tout l’Est algéien. L’objectif du préent travail est de visiter la distribution des commerces dans la ville d’Annaba en cherchant àvéifier en premier lieu la validitédu postulat selon lequel il existe une certaine spécialisation commerciale des quartiers de la ville. Il s’agit en deuxièe lieu de déerminer les logiques, si elles existent, de cette répartition. Une enquête a été réalisée en ce sens auprès des chalands et des commerçants, à travers les différents quartiers de la ville. Le but est de comprendre les motivations de fréquentations, les mobilités des clients et des commerçants, et enfin de faire un comptage manuel des commerces de la ville d’Annaba. Les réultats obtenus ont montrél’existence d’une certaine spéialisation des commerces dans la ville. L’éude àdéontréaussi une forte centralitécommerciale dans la ville qui se base sur une centralité orphologique et fonctionnelle. The city of Annaba is the fourth largest city in Algeria located in the extreme northeast of Algeria. Its tourist character, combined with its economic dynamism and commercial vitality, gives it a status of very attractive territory radiating throughout the Algerian East. The objective of this work is to visit the distribution of shops in the city of Annaba, seeking to verify in the first place the validity of the postulate according to which there is a certain commercial specialization of the districts of the city. The second step is to determine the logic, if any, of this distribution. A survey was carried out in this regard among barges and traders, throughout the various districts of the city, the aim is to understand the motivations of the customers and the shopkeepers, and finally to make a manual count of the shops of the city of Annaba. The results obtained showed the existence of a certain specialization of shops in the city. The study also demonstrated a strong commercial centrality in the city based on morphological and functional centrality.
Attractivite et qualite de vie, cas de la Ville D’Oum El Bouaghi
(Université D’Oum El Bouaghi, 2021-11-02) Nadjar, Sarra Ismahane; Mazouz; Said
L’attractivité d’un territoire est généralement assimilé à la capacité de ce territoire à attirer et à retenir les facteurs mobiles de production et/ou de population. L’attractivité territoriale est composée de plusieurs types et composantes, un de ces types est l’attractivité lié au cadre de vie, qu’est la capacité d’une ville, d’un territoire ou d’un quartier d’attirer et de donner envie de venir et de rester en offrant le meilleur cadre de vie, la meilleure offre urbaine (espaces publics, équipements, services, commerces, etc.), la sécurité, l’offre scolaire et universitaire qui deviennent des éléments décisifs dans les choix de localisation résidentielle. Certains l’appellent attractivité résidentielle qui est à son tour multiple par les différents acteurs qui peuvent être attiré que ce soit des touristes, des cadres, des hommes d’affaires, des consommateurs, des entreprises… etc. L’objectif de cette contribution est d’analysé l’attractivité de la ville d’Oum el Bouaghi lié au cadre de vie à travers un quartier d’habitat collectif. La recherche procède par une modélisation de l’espace par le biais des techniques de la syntaxe spatiale en se basant sur les propriétés d’accessibilité et par un questionnaire dédié aux habitants. Améliorer la qualité de vie, améliorer l’attractivité? L’attractivité est une conséquence de la qualité de vie : améliorer le quotidien des habitants participe à l'amélioration de l'attractivité de leur territoire. Le diagnostic de la qualité de vie à la ville d’Oum el Bouaghi nous a permis de dégager certains déséquilibres dont il faut traiter et des opportunités dont il faut profiter au futur pour l’amélioration de l’attractivité et la qualité de vie à la ville.
Bandwidth Provision through Disjoint Multipath RPL in the IoMT
(University of Oum El Bouaghi, 2021-05-25) Kettouche, Souhila; Maimour, Moufida; Derdouri,Lakhdar
Internet of Multimedia Things (IoMT) is one extensively current topic of the Internet of Things (IoT) due to the immersive growth of multimedia applications in several fields. In LowPower and Lossy Networks (LLNs) where sensor nodes are a key component, providing a satisfactory quality of service (QoS) as well as a user quality of experience (QoE) for such applications is a challenging task. In fact, high bandwidth and substantial computation resources are required. To provide sufficient bandwidth to handle these high data rate applications, we propose to extend RPL to enable for simultaneous use of disjoint multiple paths. This is done on top of the already maintained DODAG structure with the least induced overhead. Furthermore, we suggest applying a low-complexity encoding method on the captured images. Based on both QoS and QoE metrics, we evaluate the performance of our disjoint multipath RPL (DM-RPL) for real video clip transmission using the IoTLAB testbed. Our results show that multipath provides more bandwidth as the PDR is increased. Video quality is further improved thanks to the adopted data reduction at the source. All of this translates into less energy being consumed.
Behavioural verification of limited resources systems under true concurrency semantics
(University of Oum El Bouaghi, 2021-05-25) Bouneb; Messaouda; Saidouni; Djamel Eddine
In this paper we propose a true concurrency semantics for limited resources systems using K-bounded Petri net as modeling formalism and maximality labeled transition system (MLTS) as semantics model. Indeed the model of MLTS expresses clearly the semantics of true parallelism of concurrent systems. The proposed operational maximality semantics for Kbounded Petri nets makes it possible to interpret any K-bounded Petri net in terms of MLTS. Through an example we show the interest of the proposed semantics in comparison with the interleaving semantics and the ST semantics. The comparison concerns the preservation of true concurrency and the reduction of the size of the semantics model. Furthermore, we will show that expected CTL properties may be verified on the corresponding maximality labeled transition system of a modeled system using our developed tool.

(University of Oum El Bouaghi, 2021-10-05) Boukersoul, Nasre Eddine; Aissaoui, Nasre Eddine
This study aims to emphasize on the importance of accounting education in universities, especially in the context of Algeria. In order to improve the quality of accounting education, we analyzed the IAESB requirements along with related cases that were conducted in the process of bridging the gap between accounting courses and labor market. This study also intends to enrich local literature regarding the subject of accounting education as the future convergence of Algerian professional bodies toward the international accounting education. تهدف هذه الدراسة إلى التأكيد على أهمية تعليم المحاسبة في الجامعات وخاصة حالة الجزائر لضمان ترسيخ مفهوم الجودة. لقد قمنا بتحليل متطلبات IAESB جنبًا إلى جنب مع مراجعة بعض الحالات ذات الصلة لمحاولة سد الفجوة بين المناهج المحاسبية وسوق العمل. تثري هذه الدراسة أيضًا الأدبيات المحلية فيما يتعلق بموضوع تعليم المحاسبة باعتباره التقارب المستقبلي للهيئات المهنية الجزائرية تجاه تعليم المحاسبة الدولي .
Biometric Image Encryption Scheme based on Modified Double Random Phase Encoding System
(University of Oum El Bouaghi, 2021-05-25) Yahi, Amina; Bekkouche, Tewfik; Diffellah, Nacira; Daachi, Mohamed El Hossine
In this paper, an opto-digital encryption scheme based on a modified Double Random Phase Encoding (DRPE) system is proposed. Two biometric modalities are used in this work which is the face and the corresponding finger print of the same person. Firstly the face biometric image is encrypted chaotically using the permutation-diffusion architecture. Then obtained encrypted face is multiplied element by element by a constructed mask formed by injecting the finger print image within the phase of this mask. The obtained result will be transformed into a frequency domain by the two-dimensional. Fourier transform or any of its derivatives, resulting complex image is exactly the encrypted biometric image. Experiment computer simulations confirm the efficiency of this work in terms of histogram analysis, loss data and sensitivity test when compared with existing works.
Cardiopulmonary exercise testing : an overview
(University of Oum El Bouaghi, 2022-04-23) Adda,oudjedi; Bekachout, Ahmed; Allali.Abdelghani
Cardiopulmonary exercise testing(CPET) is an objective assessment of functional capacity. It has become increasingly popular in clinical, research,and athletic performance settings. One of the most valuable applications of clinical exercise testing is the ability to distinguish cardiovascular from pulmonary causes of exercise limitation. In addition, CPET is underutilized in Algerian hospitals and medical centers due to the limited availability of CPEX equipment and the personnel skilled in its application. اختبار الجهد البدني مع قياس الوظائف القلبية التنفسية هو تقييم موضوعى للقدرة الوظيفية. فقد أصبح شائعا ويستخدم بنطاق واسع في المجال الإكلنيكى ، مجال البحث العلمى والأداء الرياضى يعتبر إختبار الجهد البدنى مع قياس الوظائف القلبية التنفسية كإجراء إكلنيكى مهم خصوصا وذلك لقدرته على تمييز القصور القلبى الوعائى من القصور الرئوي كأسباب للحد من الجهد البدنى. وبالإضافة إلى ذلك ، لا يُستخدم هذا الإختبار في المستشفيات والمراكز الطبية الجزائرية استخداما كافيا بسبب محدودية المعدات والأجهزة والمتمرسين المهرة في تطبيقاته.
Compétences Professionnelles des Diplômés en Comptabilité: Ecart des Attentes en matière de l'Enseignement Comptable en Algérie
(Université D’Oum El Bouaghi, 2021-10-05) Djoudi, Imane; Abdelouahad, Nassima
L'objectif de cette étude est d'examiner si l’enseignement comptable actuelle des universités algériennes conduit à améliorer le niveau des étudiants en comptabilité et à leur fournir les compétences professionnelles requises par les différentes entreprises et établissements. Pour atteindre cet objectif, la réalité de l’enseignement de la comptabilité en Algérie a été mise en évidence et un questionnaire a été utilisé pour recueillir les opinions d'un échantillon des enseignants de comptabilité de différentes universités. L'étude a révélé un grand écart entre les cursus couverts par l'enseignement comptable et les compétences nécessaires pour développer la profession comptable. Cela est principalement dû au fait que l'enseignement de la comptabilité à l'Université Algérienne suit toujours la méthode traditionnelle et se concentre principalement sur le côté théorique et manque d'exigences pour l'amélioration et la mise à jour des méthodes d'enseignement recommandées par les organismes internationaux pour la formation en comptabilité. Le manque de praticité, le manque d’utilisation des moyens techniques et l’absence de coopération entre universitaires et professionnels ont largement contribué à élargir la lacune. L'étude a recommandé que les universités algériennes déploient davantage d'efforts et de moyens et définissent une stratégie bien pensée et efficace en commençant à revoir et à mettre à jour leurs programmes pour améliorer la qualité de l'enseignement comptable afin de suivre le rythme des besoins du marché en constante évolution. الهدف من هذه الدراسة هو فحص ما إذا كان التعليم المحاسبي الحالي في الجامعات الجزائرية يؤدي إلى تحسين مستوى طلاب المحاسبة وتزويدهم بالمهارات المهنية التي تتطلبها الشركات والمؤسسات المختلفة. ولتحقيق هذا الهدف تم تسليط الضوء على واقع التعليم المحاسبي في الجزائر واستخدم استبيان لجمع آراء عينة من أساتذة المحاسبة من جامعات مختلفة. كشفت الدراسة عن وجود فجوة كبيرة بين المقرا رت التي يشملها تعليم المحاسبة والمها ا رت اللازمة لتطوير مهنة المحاسبة. ويرجع ذلك بشكل أساسي إلى حقيقة أن التعليم المحاسبي في الجامعة الجزائرية لا يزال يتبع الطريقة التقليدية ويركز بشكل أساسي على الجانب النظري ويفتقر إلى متطلبات تحسين وتحديث طرق التدريس التي أوصت بها المنظمات الدولية للتعليم المحاسبي. وقد ساهم الافتقار إلى التطبيق العملي والافتقار إلى استخدام الوسائل التقنية وانعدام التعاون بين الأكاديميين والمهنيين إلى حد كبير في توسيع الفجوة. وأوصت الدراسة بأن تبذل الجامعات الجزائرية المزيد من الجهد والموارد وتحديد استراتيجية مدروسة وفعالة من خلال البدء في مراجعة وتحديث برامجها لتحسين جودة التعليم المحاسبي من أجل مواكبة احتياجات السوق المتغيرة باستمرار .
Compressed VGG16 Auto-Encoder for Road Segmentation from Aerial Images with Few Data Training
(University of Oum El Bouaghi, 2021-05-25) Abdeldjalil, Kebir; Taibi, Mahmoud; Serradilla, Francisco; Spain, Madrid
Deep Learning methods have found many applications such as segmentation, recognition and classification. However, almost all of these methods require large data-set for the training step and a long training time. Indeed, in surveillance video domain, as for many real-world applications, samples are only accessible in limited amounts owing to acquisition and experiments complexity. In this work, we introduce compressed VGG Auto-Encoder system for road image segmentation in highresolution aerial imagery. The objective of our experiments is to improve the methodology of distinguishing the road network when only few Data is available. We propose an approach based on compressed Auto-encoder; focus on avoiding the over-fitting effect by generating new data augmentation, based on basic filter transformation to increase and enhance the quality of data training, in the aim of learn an appropriate and simplified representation of data from the original data set in order to obtain a deeper insight from large data-set, and to achieve a quick segmentation training time. Our model achieve a good result and is considered as the best network for fast and accurate segmentation of road images, compared to other models. Furthermore, we provide an explanation of these techniques and some recommendation for their use in the field of deep learning.
Deep Neural Transformer Model for Mono and Multi Lingual Machine Translation
(University of Oum El Bouaghi, 2021-05-25) Khaber, Mohamed Islam; Frahta, Nabila; Moussaoui, Abdelouahab; Saidi, Mohamed
In recent years, the Transformers have emerged as the most relevant deep architecture, especially machine translation. These models, which are based on attention mechanisms, outperformed previous neural machine translation architectures in several tasks. This paper proposes a new architecture based on the transformer model for the monolingual and multilingual translation system. The tests were carried out on the IWSLT 2015 and 2016 dataset. The Transformers attention mechanism increases the accuracy to more than 92% that we can quantify by more than 4 BLEU points (a performance metric used in machine translation systems).

(University of Oum El Bouaghi, 2022-04-23) Slimani, Aissa; Chabane, Kahina
L’objectif de notre communication consiste en l’explication de la planification efficace des tests antidopage et le déroulement du contrôle ainsi que la conservation de l’intégrité des échantillons à partir du moment où l’athlète est informé jusqu’à celui du transport des échantillons au laboratoire d'analyse. A cet effet, nous avons choisi de passer en revue, la littérature en relation avec notre objet d’étude, afin d’illustrer les différentes techniques du contrôle antidopage. En Algérie, l’accompagnement et la moralisation de la vie sportive est assurée par l'Agence nationale antidopage selon une règlementation en conformité avec celle de l’Agence mondiale antidopage (AMA) et la mise en œuvre de mécanismes de contrôle des sportifs, à travers un plan national annuel. Il apparait clairement que le déroulement des contrôles antidopage est strictement codifié selon les normes de l’AMA avec des droits et des obligations ainsi qu’un personnel très compétent qui permet de remplir les particularités des différents tests. الهدف من مداخلتنا هو تسليط الضوء على التخطيط الفعال لاختبارات مراقبة تعاطي المنشطات و التحكم فيها خطوة بخطوة بالإضافة إلى الحفاظ على سلامة العينات من لحظة إخطار الرياض ي حتى نقل العينات إلى مخبر التحليل. ولهذه الغاية، اخترنا مراجعة الأدبيات فيما يتعلق بموضوع دراستنا، من أجل توضيح التقنيات المختلفة للتحكم في مراقبة تعاطي المنشطات.في الجزائر، تتم المرافقة والدعم والتحلي بأخلاقيات الحياة الرياضية من قبل الوكالة الوطنية لمكافحة المنشطات وفقًا للوائح الوكالة العالمية لمكافحة المنشطات (AMA) باستعمال آليات مراقبة الرياضيين، من خلال خطة وطنية سنوية.من الواضح أن إجراءات مراقبة تعاطي المنشطات مقنن بشكل صارم وفقًا لمعايير AMA مع الحقوق والواجبات بالإضافة إلى موظفين أكفاء للغاية يمكنهم الوفاء بخصوصيات الاختبارات المختلفة.
Distributed Secure Services Based on IoT and Blockchain for e-Health remote care
(University of Oum El Bouaghi, 2021-05-25) Reffad, Hamza; Djenaoui, Abdelatif; Alti, Adel
Nowadays, the Internet of Thing (IoT) is a potentially powerful solution for health applications. It is a smart technology that provides remote care in real time and requires low latency health data processing and transmission. The large number of connected objects to Cloud can be a problem for low-latency workloads, which is the case of several health mobile applications. To this end, Fog Computing, has emerged, where Cloud computing is extended to the edge of the network to reduce latency and network congestion. It provides a highly virtualized platform that provides health data storage on remote public Cloud servers to which users cannot be fully trusted, especially when we are dealing with sensitive data like health data. In fact, it becomes necessary to rethink a new more robust secure technique. To provide such technique, we proposed a new secure solution called IoToDChain for e-Health mobile application, based on cryptographic techniques especially Elliptic Curve Diffie Hellman-RSA and the Blockchain paradigm. They exchange of a secret key in confidential and robust manner and protect patients’ privacy in a mobile-Fog-Cloud environment. The experiments achieved promising results for good data protection against the most known attacks in healthcare systems.
