Existing works, however, still suffer from privacy-related challenges chief being privacy breaches based on blockchain digital footprints from health facilities, doctors, and patients alike as well as feasibility challenges. Empirical research from state-of-the-art demonstrates the possibility to deanonymize entities involved in a blockchain transaction via inference analysis using such digital footprints on-chain. In this paper, we address such lacunae by advancing a privacy-conscious feasible blockchain-agnostic EHR sharing framework leveraging anonymous transactions, a smart contract, and decentralized storage technology. We construct a constant-size identity-based ring signature to provide accentuated privacy for transaction initiators and demonstrate how health facilities can anonymously retrieve anonymous data on-chain to facilitate EHR sharing via a novel, robust yet computationally efficient, and privacy-aware algorithm dubbed PatientFinder. We subsequently show proof of concept of our framework. A thorough system evaluation is performed revealing that the solution satisfies the privacy of patients and health facilities (doctors), feasibility, and security-related requirements.","PeriodicalId":39673,"journal":{"name":"International Journal of Computers and Applications","volume":"21 1","pages":"564 - 578"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82504363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To surmount this barrier and advance the field, we propose an innovative optimization of the K2PC algorithm for Bayesian network structure learning. Derived from the popular K2 algorithm, our novel optimization ingeniously tackles K2PC's vulnerability to predetermined node order. Leveraging the power of a particle swarm optimization algorithm, we adeptly seek the optimal node ordering, yielding exceptional results. Through rigorous evaluations on benchmark networks, our proposed method surpasses prior approaches in structure difference and accuracy, affirming its potential as a promising avenue for Bayesian network structure learning in large, complex networks. We posit that our novel approach constitutes an important advance in the field of Bayesian network structure learning, with the potential to stimulate additional progress through further scientific investigation.","PeriodicalId":39673,"journal":{"name":"International Journal of Computers and Applications","volume":"1 1","pages":"553 - 563"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83425579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stored medical data remains the main target for hackers, and hence it needs to be stored securely. To achieve this objective, this paper proposes a novel model using Delegated Proof of Stake-Hyper ledger Fabric Block Chain (DPOS-HFBC). Primarily, by employing LL Subbandeigen Value decomposition employed Discrete Wavelet Transform (L2-DWT), the patient’s Lung Computed Tomography (CT) image data are collected and embedded. For embedding, the patient’s name and ID are taken. In embedding, a Pseudorandom number generator using the Mersenne twister algorithm employed in Elliptic Curve Cryptography (PM-ECC) is applied for key encryption. It covered the image that was embedded with the original and then stored in DPOS-HFBC. Likewise, for authorization, every patient’s biometric ID was hashed and stored in DPOS-HFBC. Data requesters request data in the Interplanetary File System (IPFS) of DPOS-HFBC, and the attributes from the request are extracted and sent to the authority for verification. After verifying, the authority shares their biometric ID with the requester and this gets hashed and then verified in DPOS-HFBC. To show the model’s supremacy, the proposed method was evaluated and compared with existing methods.","PeriodicalId":39673,"journal":{"name":"International Journal of Computers and Applications","volume":"103 1","pages":"516 - 522"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79456098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have used machine learning to predict software defects. However, complex structures and imbalanced class distributions in software defect data make learning an effective defect prediction model challenging. In this article, two deep learning-based defect prediction models using static code metrics are proposed. In order to enhance the learning process and improve the performance of the proposed models, pool-based active learning is employed. In this regard, the possibility of using active learning to mitigate the need for a large amount of labeled data in the process of building deep learning models is investigated. To deal with imbalanced distribution of software modules between defective and non-defective classes, Near-Miss under-sampling and KNN, with different number of neighbors, are used. The reason for choosing them is their good performance in binary classification problems. Experiments are performed on two well-known, publicly available datasets, GitHub Bug Dataset and public Uniﬁed Bug Dataset for java projects. The evaluation results reveal the effectiveness of our proposed models in comparison to the traditional machine learning algorithms. In the conducted investigations on the Unified Bug Dataset, at the file level, the value of F-measure and AUC criteria have improved by 13 and 11 percent, respectively and at the class level, the values have improved by 14 and 11 percent, respectively.","PeriodicalId":39673,"journal":{"name":"International Journal of Computers and Applications","volume":"16 1","pages":"534 - 552"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81283313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ciphertext policy attribute based encryption (CPABE) scheme allows data owners to impose access control on their cloud-resident sensitive data. This paper has studied the approaches adopted to revoke users by the existing bilinear pairing cryptography based CPABE schemes. The existing studies have suggested solutions to revocation either by updating the non-revoked users’ keys or updating the ciphertext. Such approaches increase computational overhead for resource-constrained devices. In addition, a few studies have discussed the possibility of the CSP becoming dishonest and colluding with the revoked users. The likelihood of a collusion attack caused by the CSP and the revoked users also needs extensive attention. The development of the proposed proxy-based framework aims to extend the existing CPABE scheme and simplify the revocation of access rights at the user and attribute level with scalability, dynamicity, collusion resistance, and forward/backward secrecy. The proposed framework uses bilinear pairing cryptography and LSSS as an access structure. Furthermore, the security and performance analysis of the proposed framework reflects that it is implementable, better, and more secure than the existing work.","PeriodicalId":39673,"journal":{"name":"International Journal of Computers and Applications","volume":"42 1","pages":"523 - 533"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91333103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By considering the input data’s distributive nature and large dimensionality, outlier detection becomes a challenging issue. Robust outlier detection systems are crucial for data pattern prediction without labeled data. This research develops a novel approach based on stacking auto encoders over Long-Short Term Memory (LSTM) for outlier prediction. The detection accuracy of outlier detection is improved with the hyperparameters optimized with the Chaotic Gravitational Search Algorithm (CGSA). CGSA minimizes the training loss with enhanced detection accuracy in the proposed outlier detection process. The auto encoder in outlier detection transforms the input into a latent space representation to generate the original input sequence. The involvement of learning parameters computes and minimizes the errors between input and generated sequences. The proposed work is experimented and compared with state-of-the-art approaches of recent research. Using the proposed approach, the performance of outlier prediction is improved with an accuracy of98.6%, sensitivity of 96.1%, specificity of 97.8%, G-mean of 96%, Area Under Curve (AUC) of 0.935, Hit rate of 92.3%.

Although recommender systems do this work efficiently, problems such as Cold Start often appear when new users or items enter the system. The traditional methods of recommender systems, collaborative filtering and content–based techniques, do not offer an optimized solution to this problem. The integration of neural networks in recommender systems offers a new approach to solving cold start. Whether using the feature of extracting hidden data, or using deep learning algorithms with more layers, the accuracy of recommendations and predictions has increased significantly. We have analyzed 40 papers that approached solving the cold start problem using neural networks. We have researched how neural networks are integrated into recommender systems, what they are used for, which neural network algorithms have shown to be more efficient in solving the cold start problem, and which algorithms have increased the accuracy of the recommendation. We aim to answer these questions with other subquestions related to types of cold start such as item or user cold start and warm, partial, or strict cold start.","PeriodicalId":39673,"journal":{"name":"International Journal of Computers and Applications","volume":"95 1","pages":"485 - 496"},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81853183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
