Assured Deletion: A Scheme Based on Strong Nonseparability

Cloud storage services bring great convenience to users, but also make data owners lose direct control of their data. How to ensure that deleted cloud data can never be recovered by cloud servers or attackers is a key issue in the field of cloud storage security, which is important to protect user privacy and data confidentiality in the cloud environment. Most existing schemes have the drawbacks of overreliance on key destruction and having the ability to decrypt part of the ciphertext after cracking the key. To solve these problems, a novel cloud data assured deletion scheme based on strong nonseparability is presented. By combining XOR operation with the block cipher, the cipher data become strongly nonseparable; thus, destroying any piece of cipher data will result in unrecoverable original data. Theoretical analysis and experimental results both show that the scheme achieves the expected goals of assured deletion, which has obvious performance advantages and stronger security compared with similar schemes.

Web-Based File Clustering and Indexing for Mindoro State University

Purpose – The Web-Based File Clustering and Indexing for Mindoro State University aim to organize data circulated over the Web into groups/collections to facilitate data availability and access, and at the same time meet user preferences. The main beneﬁts include: increasing Web information accessibility, understanding users’ navigation behavior, improving information retrieval and content delivery on the Web. Web-based file clustering could help in reaching the required documents that the user is searching for. Method – In this paper a novel approach has been introduced for search results clustering that is based on the semantics of the retrieved documents rather than the syntax of the terms in those documents. Data clustering was used to improve the information retrieval from the collection of documents. Data were processed and analyzed using SPSS (version 18) where the instrument was evaluated to test the reliability and validity of the measures used. Evaluation was based on a Likert scale of Excellent, Good, Fair, and Poor as described for the selected quality characteristics. Results – A total of 200 questionnaires were distributed with a return rate of 100%. The questionnaire was tested 0.735 using Cronbach’s Alpha Coefficient and considered a reliable instrument. Four quality characteristics were evaluated in this study; Usability, Performance Efficiency, Reliability, and Functionality Suitability. Conclusion - The Web-based file clustering could help in reaching the required documents that the user is searching for. The need for an information retrieval mechanism can only be supported if the document collection is organized into a meaningful structure, which allows part or all the document collection to be browsed at each stage of a search. Recommendations – It is recommended that upon uploading of file it will show the use of the file and where it is originated (department). It is also recommended to create an index to cluster not only the file type but also the content and use of a file. Explore the clustering to a wider scope. Practical Implications – Document clustering provides a structure for organizing large bodies of text for efficient browsing and searching and helps a lot for the Mindoro State University for records/ document processing. Indexing is the best tool to maintain uniqueness of records in a database. Whenever new files or records are created, it can be easily added to the index.

Enhancing Machine Learning Models by Augmenting New Functionalities

The area of educational data mining is expansive, and machine learning models play a significant role in improving online educational environments. The e-Learning platforms previously used for distance learning and education tend to find their place in full-time education as an add-on for resources management and better interaction between users. This chapter tackles the problem of enhancing the machine learning models by offering methods for gathering more data that can be fitted in the actual datasets or building new datasets for specific tasks. The methods divide into three areas: messages, social media, and forum activities; each offers techniques for improving models by adding more data and more data and features. The experiments show that the gathered data can produce highly accurate models. The usefulness of such approaches is beyond improving the accuracy because these methods enable other functionalities like recommender systems that can be integrated (or enhanced if there are already) in the online educational environments.

Research on a Virtual Machine Mode Transfer Method Supporting Energy Consumption Optimization

In traditional cloud resource optimization scheduling, excessive pursuit of service performance and system reliability has resulted in low utilization of system resources and severe energy dissipation. In this paper, transfer target of virtual machines was taken into account with respect to the above problem, including virtual machine mode transfer method, hot mode sleep selection method and cold mode wake-up selection method that support energy protection. In other words, the operating mode and hot mode virtual machines are converged in a cluster of physical machines of minimum amount to reduce energy consumption by shutting down idle physical machines; the cold mode virtual machines are converged in another cluster of physical machines of as few physical machines as possible to reduce energy consumption through collective sleep. The experimental results show that the energy optimization resource adjustment strategy in this paper reduces the energy consumption of the system while ensuring the required system performance and reliability.
