This allows the user to enjoy the personalized services without fearing full inter-domain tracking. To achieve this, we propose a solution that attempts to introduce layers of anonymization serving as temporary identities to be used by the user while browsing. Those identities will be used for limited time (to sustain the customization and user experience resulting from tracking), and then discarded for a new identity. This approach allows the user to divide the activity into profiles which eliminates browsing history spilling over to other sessions.

Through the exchange of messages, mesh clients (MCs) and mesh routers (MRs) initiate the operation, allowing the client to authenticate itself with the foreign mesh router (FMR). In existing protocols, these messages were shared in plaintext format, making it easy for an attacker to breach their integrity. Therefore, a secure communication method should be established between MCs and MRs for message exchange.

Source printer identification provides essential information about the origin and integrity of a printed document in a fast and cost-effective manner. Even when fraudulent documents are identified, information about their origin can help stop future frauds. If a smartphone camera replaces scanner for the document acquisition process, document forensics would be more economical, user-friendly, and even faster in many applications where remote and distributed analysis is beneficial. Building on existing methods, we propose to learn a single CNN model from the fusion of letter images and their printer-specific noise residuals. In the absence of any publicly available dataset, we created a new dataset consisting of 2250 document images of text documents printed by eighteen printers and acquired by a smartphone camera at five acquisition settings. The proposed method achieves 98.42% document classification accuracy using images of letter ‘e’ under a 5 × 2 cross-validation approach. Further, when tested using about half a million letters of all types, it achieves 90.33% and 98.01% letter and document classification accuracies, respectively, thus highlighting the ability to learn a discriminative model without dependence on a single letter type. Also, classification accuracies are encouraging under various acquisition settings, including low illumination and change in angle between the document and camera planes.</p></div>","PeriodicalId":48638,"journal":{"name":"Journal of Information Security and Applications","volume":"84 ","pages":"Article 103804"},"PeriodicalIF":5.6,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141324181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, we introduce a data processing method to mitigate measurement error and enhance robustness. Secondly, we present a multipath transmission simulation method to convert the measured performance disparity between correlated links into statistical features. Thirdly, we propose a dynamic threshold calculation method, which utilizes the statistical features to determine thresholds based on extreme value theory and probability distribution fitting. Finally, CLV identifies the fabricated link within correlated links based on the thresholds and current statistical features.

It uses a permutation algorithm to shuffle data. In today’s Post-Quantum Cryptography (PQC), hiding countermeasure has earned the limelight for its “shufflability” in lattice-based, and code-based, cryptographic algorithms. In this narrative, most importantly, as a rule, fast generation of permutations is paramount to both efficacy and security of an algorithm. The Fisher–Yates (FY) shuffling method has long been a popular choice for this purpose: the FY method generates randomly shuffled (finite) indices. However, despite its theoretical verity, with the FY method we anticipate the following risks of misuse, which can lead to biased shuffling sequences: (i) incorrect implementation, (ii) poor random source, and (iii) the chosen random number being too small. In this paper, we introduce a new statistical test called “approximate permutation criterion” (“APC”). We use it to examine some known cases of misused FY shuffling (i–iii). APC takes into consideration the fact that the super-exponential rate of growth of the factorial function <span><math><mrow><mi>N</mi><mo>!</mo></mrow></math></span>, which represents the number of permutations of <span><math><mi>N</mi></math></span> indices, defies any meaningful form of statistical tests. With APC one can verify whether the output permutations are biased or not with much lower testing cost. Mathematically, in this paper we introduce the so-called “<span><math><mi>k</mi></math></span>th order permutation verification”, the underpinning notion upon which APC is based. We also compare APC with full sample space to demonstrate how well it encapsulates the statistical randomness of random permutations.

Based on the original completely collusion resistant traitor tracing scheme, the uniform distribution of hash output is used to prevent malicious encryptors. In addition, users can perform authentication during the decryption phase to prevent replay attacks. At the same time, the puncture algorithm is introduced, so that normal users can dynamically revoke themselves without affecting the normal use of other users.
