It stipulates that the data controller receiving individual data deletion request shall not only erase the required data, but also take reasonable steps to inform other data controllers to delete the same data. Prior to irrecoverable data erasure, it is of paramount importance to design a distribution and acknowledgement process of deletion notifications across involved data controllers. The design of such a mechanism is faced with the following challenges: 1) completeness: Ensuring that all relevant data controllers, who possess the data slated for erasure, are duly informed; 2) robustness: Immune from malicious attacks when deletion notifications traverse through untrusted networks; 3) lightweight: Reduce the right to deletion compliance cost and accommodate more deletion requests for data controllers. To this end, this article proposes DelRightGuard, which is the first attempt to tackle with the aforementioned challenges. DelRightGuard is built on a cross-plane cooperation architecture between regulatory and service planes. Within regulatory plane, DelRightGuard proposes a cuckoo filters based on data circulation recording algorithm to efficiently ensure the completeness of deletion notifications. Within service plane, DelRightGuard devises a secure yet lightweight deletion notification distribution protocol that runs on a network function hosted by each data controller. This protocol employs HMAC based hop-by-hop forward traversal verification, recursive backward acknowledgement and probabilistic sampling verification, so that it ensure the robustness and lightweight of deletion notification distribution process. We implement a prototype for DelRightGuard. The experimental result confirms that it is practical with acceptable performance.</div></div>","PeriodicalId":100790,"journal":{"name":"Journal of Information and Intelligence","volume":"3 4","pages":"Pages 303-325"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895163","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}

Notably, the auxiliary information provided by online social platforms offers significant support for enhancing the performance of recommendation systems. Based on the hypothesis that socially connected users share similar preferences, integrating social relationships as supplementary information into recommendation algorithms can significantly enhance recommendation accuracy while effectively mitigating the cold-start problem. However, existing social recommendation systems primarily rely on explicit social relationships as auxiliary information, often overlooking the value of potential social connections. Research indicates that users with potential social links may also possess valuable preference information. We believe that mining potential social relationships can provide valuable auxiliary information, thereby enhancing the performance of recommendation systems. To address this issue, we propose a social recommendation model based on social semantic mining and denoising (SSMD). Specifically, we propose an encoder-decoder architecture to learn explicit social user representations and mine potential social relationships. Considering the potential noise in these implicit connections, we design a denoising module that utilizes user preference information to filter unreliable social links. Furthermore, we implement cross-view information alignment between the potential social graph and interaction graph through an auxiliary loss function. Extensive experiments conducted on multiple public datasets demonstrate that our SSMD method outperforms various baseline approaches with significant improvements.</div></div>","PeriodicalId":100790,"journal":{"name":"Journal of Information and Intelligence","volume":"3 4","pages":"Pages 361-374"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895166","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}

In SR networks, utilizing active reconfigurable intelligent surface (RIS) as the secondary transmitter (STx) enhances this mutual benefit compared to passive RIS. This paper addresses the interference management challenges that inevitably arise from employing active RIS. We consider a common SR network consisting of three types of users: SR users, non-SR users, and eavesdroppers. Additionally, each SR user has their own unique cellular services. We propose minimizing the total power consumption while satisfying a sufficiently large signal-to-interference-plus-noise ratio (SINR) for SR users, a small enough SINR for eavesdroppers, and a small enough interference temperature for non-SR users. The alternative optimization (AO) method is used for decoupling multi-variables. The non-convex constraints are relaxed as convex ones through first-order Taylor approximation, and the bounded channel state information (CSI) error model is handled using the S-procedure. Simulations validate the superiority of the proposed algorithm and demonstrate that the total power consumption is minimized while meeting performance thresholds.

In this paper, we propose a multi-scale attention residual neural structure for improved channel estimation of OTFS waveforms in different satellite-ground scenario. Firstly, a multi-scale channel feature extraction module is designed, which applies multi-dimensional feature extraction to the channel matrix, thereby bolstering the capability to capture features at diverse scales. Subsequently, a self-attention mechanism is incorporated to concentrate on subtle yet significant features. The extracted features are then integrated and exploited through a residual convolutional architecture to derive an estimation of the channel matrix. Simulations are conducted using the satellite-ground mobile channel model outlined in 3GPP TR 38.811, with the NTN-TDL-C and NTN-TDL-B channel models representing line of sight (LoS) and non-line of sight (NLoS) conditions, respectively.

Prior research typically utilizes multimodal data to construct item graphs, often overlooking the nuanced details within the data. As a result, these studies fail to thoroughly examine the semantic relationships between items and user behavioral patterns. Our proposed approach, METRIC, addresses this gap by delving deeper into multimodal information. METRIC consists of two primary modules: the multiple preference modelling (MPM) module and the item semantic enhancement (ISE) module. The ISE module performs relational mining across multiple attributes, leveraging the semantic structural relationships inherent in items. In contrast, the MPM module enables users to articulate their preferences across different modalities and facilitates adaptive fusion through an attention mechanism. This approach not only improves precision in capturing user preferences and interests but also minimizes interference from varying modalities. Our extensive experiments on three benchmark datasets substantiate METRIC's superiority and the efficacy of its core components.</div></div>","PeriodicalId":100790,"journal":{"name":"Journal of Information and Intelligence","volume":"3 3","pages":"Pages 242-256"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144490378","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}
