Social Media Risk Perceptions Of Human Resource Professionals: Issues Undergraduate Students Should Consider, Julio C. Rivera, Jack Howard, Samuel Goh, James L. Worrell, Paul Di Gangi
Journal of Cybersecurity Education, Research and Practice
This study contrasts the social media risk perceptions of undergraduate students, versus those of certified Human Resource professionals. Social media is widely used by most segments of the population, and particularly among the age group that includes most undergraduate students. Organizations hiring employees are increasingly examining job applicant's social media postings as part of the applicant screening process. In this study we examine how these groups differ in their perceptions of the risks inherent in using social media, and what these differences may mean for students seeking employment. Recommendations are made for raising undergraduate student awareness of these risks.

Multiple Content Adaptive Intelligent Watermarking Schemes For The Protection Of Blocks Of A Document Image, Chetan Kr Mr., S Nirmala Dr.
Journal of Digital Forensics, Security and Law
Most of the documents contain different types of information such as white space, static information and dynamic information or mix of static and dynamic information. In this paper, multiple watermarking schemes are proposed for protection of the information content. The proposed approach comprises of three phases. In Phase-1, the edges of the source document image are extracted and the edge image is decomposed into blocks of uniform size. In Phase-2, GLCM features like energy, homogeneity, contrast and correlation are extracted from each block and the blocks are classified as no-information, static, dynamic and mix of static and dynamic information content …

Journal of Digital Forensics, Security and Law
Consumer grade broadband routers are integral to accessing the Internet and are primarily responsible for the reliable routing of data between networks. Despite the importance of broadband routers, security has never been at the forefront of their evolution. Consumers are often in possession of broadband routers that are rich in consumer-orientated features yet riddled with vulnerabilities that make the routers susceptible to exploitation. This amalgamation of theoretical research examines consumer grade broadband routers from the perspective of how they evolved, what makes them vulnerable, how they are targeted and the challenges concerning the application of security. The research further explores …
Evidence Verification Complications With Solid-State Drives, Ryne Teague, Michael Black
Evidence Verification Complications With Solid-State Drives, Ryne Teague, Michael Black
Journal of Digital Forensics, Security and Law
Solid-state drives operate on a combination of technologies that create a barrier between the physical data being written and the digital forensics investigator. This barrier prevents the application of evidence verification methods developed for magnetic disk drives because the barrier prevents the investigator from directly controlling and therefore verifying that the underlying physical data has not been manipulated. The purpose of this research is to identify a period of inactivity where the underlying physical data is not being manipulated by wear leveling or garbage collection routines such that evidence can be reliably verified with existing hashing algorithms. An experiment is …

A Data Hiding Scheme Based On Chaotic Map And Pixel Pairs, Sengul Dogan Sd
Journal of Digital Forensics, Security and Law
Information security is one of the most common areas of study today. In the literature, there are many algorithms developed in the information security. The Least Significant Bit (LSB) method is the most known of these algorithms. LSB method is easy to apply however it is not effective on providing data privacy and robustness. In spite of all its disadvantages, LSB is the most frequently used algorithm in literature due to providing high visual quality. In this study, an effective data hiding scheme alternative to LSB, 2LSBs, 3LSBs and 4LSBs algorithms (known as xLSBs), is proposed. In this method, random …

Secure Server-Aided Top-K Monitoring, Yujue Wang, Hwee Hwa Pang, Yanjiang Yang, Xuhua Ding
Research Collection School Of Computing and Information Systems
In a data streaming model, a data owner releases records or documents to a set of users with matching interests, in such a way that the match in interest can be calculated from the correlation between each pair of document and user query. For scalability and availability reasons, this calculation is delegated to third-party servers, which gives rise to the need to protect the integrity and privacy of the documents and user queries. In this paper, we propose a server-aided data stream monitoring scheme (DSM) to address the aforementioned integrity and privacy challenges, so that the users are able to …

It is widely acknowledged that the collaborations with more users increase productivity. Secure cloud storage is a promising tool to enhance such a collaboration. Access control system can be enabled with attribute-based encryption. In this system, a user encrypts and uploads his/her data to the cloud with an access policy, such that only people who satisfy that access policy can decrypt the data. When a recipient would like to enable another person who is originally unauthorized by the original access policy, this recipient will need to extend the access policy by adding a new policy that includes the new person …
Multi-User Multi-Keyword Rank Search Over Encrypted Data In Arbitrary Language, Yang Yang, Ximeng Liu, Robert H. Deng
Multi-User Multi-Keyword Rank Search Over Encrypted Data In Arbitrary Language, Yang Yang, Ximeng Liu, Robert H. Deng
Research Collection School Of Computing and Information Systems
Multi-keyword rank searchable encryption (MRSE) returns the top-k results in response to a data user's request of multi-keyword search over encrypted data, and hence provides an efficient way for preserving data privacy in cloud storage systems while without loss of data usability. Many existing MRSE systems are constructed based on an algorithm which we term as k-nearest neighbor for searchable encryption (KNN-SE). Unfortunately, KNN-SE has a number of shortcomings which limit its practical applications. In this paper, we propose a new MRSE system which overcomes almost all the defects of the KNN-SE based MRSE systems. Specifically, our new system does …

Vkse-Mo: Verifiable Keyword Search Over Encrypted Data In Multi-Owner Settings, Yinbin Miao, Jianfeng Ma, Ximeng Liu, Junwei Zhang, Zhiquan Liu
Research Collection School Of Computing and Information Systems
Searchable encryption (SE) techniques allow cloud clients to easily store data and search encrypted data in a privacy-preserving manner, where most of SE schemes treat the cloud server as honest-but-curious. However, in practice, the cloud server is a semi-honest-but-curious third-party, which only executes a fraction of search operations and returns a fraction of false search results to save its computational and bandwidth resources. Thus, it is important to provide a results verification method to guarantee the correctness of the search results. Existing SE schemes allow multiple data owners to upload different records to the cloud server, but these schemes have …

A Verification Framework For Stateful Security Protocols, Li Li, Naipeng Dong, Jun Pang, Jun Sun, Guangdong Bai, Yang Liu, Jin Song Dong
Research Collection School Of Computing and Information Systems
A long-standing research problem is how to efficiently verify security protocols with tamper-resistant global states, especially when the global states evolve unboundedly. We propose a protocol specification framework, which facilitates explicit modeling of states and state transformations. On the basis of that, we develop an algorithm for verifying security properties of protocols with unbounded state-evolving, by tracking state transformation and checking the validity of the state-evolving traces. We prove the correctness of the verification algorithm, implement both of the specification framework and the algorithm, and evaluate our implementation using a number of stateful security protocols. The experimental results show that …

Presence Attestation: The Missing Link In Dynamic Trust Bootstrapping, Zhangkai Zhang, Xuhua Ding, Gene Tsudik, Jinhua Cui, Zhoujun Li
Research Collection School Of Computing and Information Systems
Many popular modern processors include an important hardware security feature in the form of a DRTM (Dynamic Root of Trust for Measurement) that helps bootstrap trust and resists software attacks. However, despite substantial body of prior research on trust establishment, security of DRTM was treated without involvement of the human user, who represents a vital missing link. The basic challenge is: how can a human user determine whether an expected DRTM is currently active on her device? In this paper, we define the notion of “presence attestation”, which is based on mandatory, though minimal, user participation. We present three concrete …
