The Confidentiality of Coding Video Games with Cheat Code and Bots for Cheating in a Virtual World

Video games have been around for several decades and have had many advancements from the original start of video games. Video games started as virtual games that were advertised towards children, and these virtual games created a virtual reality of a variety of genres. These genres included sports games, such as tennis, football, baseball, war games, fantasy, puzzles, etc. The start of these games was derived from a sports genre and now has a popularity in multiplayer-online-shooting games. The purpose of this paper is to investigate different types of tools available for cheating in virtual world making players have undue advantage over other players in a competition. With the advancement in technology, these video games have become more expanded in the development aspects of gaming. Video game developers have created long lines of codes to create a new look of video games. As video games have progressed, the coding, bugs, bots, and errors of video games have changed throughout the years. The coding of video games has branched out from the original video games, which have given many benefits to this virtual world, while simultaneously creating more problems such as bots. Analysis of tools available for cheating in a game has disadvantaged normal gamer in a fair contest.

Reducing Test Anxiety while Increasing Learning Efficiency:by Using Cheat Sheet in the College English Exam

Cheat sheets are so named because they may be used by students without the instructor's knowledge to cheat on a test.Student learning is greatly enhanced by studying prior to an exam.Allowing students to prepare a cheat sheet for the exam helps structure this study time and deepens learning.The crib sheet is well defined:one double-sided page of A4.An award for the best and most creative cheat sheet allows the instructor to appreciate the students' efforts.Using the cheat sheet can not only reduces student anxiety during testing but also incease student learning efficiency.

Cheating or Coincidence? Statistical Method Employing the Principle of Maximum Entropy for Judging Whether a Student Has Committed Plagiarism

Elements of correspondence (“coincidences”) between a student’s solutions to an assigned set of quantitative problems and the solutions manual for the course textbook may suggest that the stu-dent copied the work from an illicit source. Plagiarism of this kind, which occurs primarily in fields such as the natural sciences, engineering, and mathematics, is often difficult to establish. This paper derives an expression for the probability that alleged coincidences in a student’s paper could be attributable to pure chance. The analysis employs the Principle of Maximum Entropy (PME), which, mathematically, is a variational procedure requiring maximization of the Shannon-Jaynes entropy function augmented by the completeness relation for probabilities and known information in the form of expectation values. The virtue of the PME as a general method of inferential reasoning is that it generates the most objective (i.e. least biased) probability distribution consistent with the given information. Numerical examination of test cases for a range of plausible conditions can yield outcomes that tend to exonerate a student who otherwise might be wrongfully judged guilty of cheating by adjudicators unfamiliar with the surprising properties of random processes.

Novel Solution Based on Face Recognition to Address Identity Theft and Cheating in Online Examination Systems

The main objective of this research is to provide a solution for online exam systems by using face recognition to authenticate learners for attending an online exam. More importantly, the system continuously (with short time intervals), checks for learner identity during the whole exam period to ensure that the learner who started the exam is the same one who continued until the end and prevent the possibility of cheating by looking at adjacent PC or reading from an external paper. The system will issue an early warning to the learners if suspicious behavior has been noticed by the system. The proposed system has been presented to eight e-learning instructors and experts in addition to 32 students to gather feedback and to study the impact and the benefit of such system in e-learning environment.

一种带作弊识别的动态(t,n)门限量子秘密共享方案

文章基于齐次线性反馈移位寄存器(Linear Feedback Shift Register,LFSR)序列和d维单量子态提出了一种带作弊识别的动态(t,n)门限量子秘密共享方案。在该方案中,可信的分发者确定共享的秘密,并为参与者分配份额,参与者对传输中的粒子执行相应的酉操作来恢复秘密。在秘密重建阶段,通过执行量子态数字签名,不仅可以检测到作弊行为,还可以识别具体的作弊者并将其删除,最终参与者可以验证恢复秘密的正确性。该方案可以在不更改旧参与者份额的前提下,无需其他参与者的帮助便可实现参与者的动态更新。安全性分析表明,该方案能够抵抗常见的外部攻击和内部攻击。

有限公司股权对外转让行为的效力研究——以侵害股东优先购买权为视角

2023年《公司法》第84条就优先购买权作出规定,用以保护有限公司的人合性特征,但对侵害股东优先购买权具体情形仍未予言明,致使司法裁判和理论学说已有争议仍存在。亟待2023年《公司法》在其司法解释中对股权对外转让行为进行体系化完善。在股权转让行为方面,应采用区分原则明确股权转让行为系债权行为;在优先购买权性质认定方面,应采用公司组织法上的特殊权利说保障其他股东的顺位优势;在以侵害优先购买权主张股权转让合同无效时,应根据《民法典》规定分别对欺诈、通谋行为等情形的转让合同效力进行认定。

An Advanced Threshold Secret Sharing Scheme for Identifying Cheaters

In this paper an advanced threshold secret sharing scheme for identifyingcheaters is proposed by using authentication codes. The performance of the scheme is discussed. Theresults show that in the scheme the valid shareholders can not only identify the impersonation of anadversary, but also detect cheating of some valid shareholders . In particular one honestshareholder is able to detect cheating of other participants forming a collection, and theinformation rate of the scheme is higher than that of others.

A secure data sharing scheme with cheating detection based on Chaum-Pedersen protocol for cloud storage

With the development of cloud computing technology, data can be outsourced to the cloud and conveniently shared among users. However, in many circumstances, users may have concerns about the reliability and integrity of their data. It is crucial to provide data sharing services that satisfy these security requirements. We introduce a reliable and secure data sharing scheme, using the threshold secret sharing technique and the ChaumPedersen zero-knowledge proof. The proposed scheme is not only effective and flexible, but also able to achieve the semantic security property. Moreover, our scheme is capable of ensuring accountability of users’ decryption keys as well as cheater identification if some users behave dishonestly. The efficiency analysis shows that the proposed scheme has a better performance in terms of computational cost, compared with the related work. It is particularly suitable for application to protect users’ medical insurance data over the cloud.

Do Pay-for-Grades Programs Encourage Student Academic Cheating?Evidence from a Randomized Experiment

Pay-for-grades programs aim to incentivize families and students to engage in specified behaviors given financial remittance.In addition to doubts over its effectiveness,educators worry that monetary incentives could skew student learning motivation and lead to academic cheating.Using a randomized control trial in 11 Chinese primary schools,we studied the effects of pay-for-grades programs on academic cheating.We randomly assigned 82 classrooms into treatment or control conditions,and used a statistical algorithm to determine the occurrence of cheating.While our data indicates a concerning level of cheating overall,our experiment did not find any relationship between academic cheating and the pay-for-grades program.Finally,we discuss the feasibility of such policies in improving learning outcomes and its policy implications.

闭环供应链中再制品价格欺骗的均衡路径分析

由于市场监管缺乏和企业诚信缺失,再制品市场的价格欺骗事件层出不穷,严重损害了消费者的利益和市场配置的有效性。本文研究闭环供应链中的再制品价格欺骗问题。首先,构建一个由销售商和消费者组成的双方演化博弈模型,通过Jacobi矩阵分析混合策略的演化稳定性。结果表明:当再制品伪装之后的销售价格与伪装成本的差小于再制品不伪装的销售价格时,销售商选择不伪装,消费者选择购买,再制品市场是有效的。其次,考虑政府对销售商奖励或惩罚的措施,构建一个由销售商、消费者和政府组成的三方演化博弈模型,通过Jacobi矩阵分析混合策略的演化稳定性。结果表明:政府积极检查再制品市场,加大奖励和惩罚力度,均能促使销售商选择不伪装且消费者选择购买,市场达到有效配置。最后,通过数值分析验证相关结论的正确性。

学位撤销事由要件反思及其完善

事由要件是学位撤销构成要件的实质要素,也是学位撤销法律争议的焦点内容。基于对现行《学位条例》第十七条的解读,舞弊作伪在实质层面上构成了学位撤销的事由要件。通过对法律文本和司法案例的统合性分析,舞弊作伪作为一个不确定的法律概念,可区分为学术层面的舞弊作伪和非学术层面的舞弊作伪。相应地,学位撤销事由也可分为学位撤销的学术事由和学位撤销的非学术事由。当前,学位授予单位和法院对学位撤销事由的判断标准经常呈现不一致的情形,需要通过立法和司法的双重路径去完善学位撤销的事由要件,进而实质性化解学位撤销法律争议,有效推进教育法治。
