An Efficient PSI-CA Protocol Under the Malicious Model

Jingjie Liu,Suzhen Cao,Caifen Wang,Chenxu Liu 한국인터넷정보학회 2024 KSII Transactions on Internet and Information Syst Vol.18 No.3

Private set intersection cardinality (PSI-CA) is a typical problem in the field of secure multi-party computation, which enables two parties calculate the cardinality of intersection securely without revealing any information about their sets. And it is suitable for private data protection scenarios where only the cardinality of the set intersection needs to be calculated. However, most of the currently available PSI-CA protocols only meet the security under the semi-honest model and can’t resist the malicious behaviors of participants. To solve the problems above, by the application of the variant of Elgamal cryptography and Bloom filter, we propose an efficient PSI-CA protocol with high security. We also present two new operations on Bloom filter called IBF and BIBF, which could further enhance the safety of private data. Using zero-knowledge proof to ensure the safety under malicious adversary model. Moreover, in order to minimize the error in the results caused by the false positive problem, we use Garbled Bloom Filter and key-value pair packing creatively and present an improved PSI-CA protocol. Through experimental comparison with several existing representative protocols, our protocol runs with linear time complexity and more excellent characters, which is more suitable for practical application scenarios.

Jingjie Zhu,Mingming Cheng,Ying Wang,Jie Tan 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

While there is an increasing number of studies highlighting the power of videos in influencing audience attitudes and behavior, academic research in tourism is largely behind due to the methodological challenges of analyzing unstructured video data. This study adopts an automatic video analytics approach to examine the relationship between content features of pro-environmental videos and audience engagement in tourism. Artificial intelligence was used to extract video content features by detecting scenes and shots as well as labels (e.g., trees). Our findings suggest that there exists an inverted U-shape relationship between video informativeness and audience engagement. This study makes significant theoretical and methodological contributions to extant tourism literature by theoretically explaining and empirically testing how video content features influence audience engagement in pro-environmental video communications in tourism.

Extraction of Functional Sentence Stems (FSSs) in English Academic Texts

Jingjie Li 한국코퍼스언어학회 2016 Corpus Linguistics Research Vol.2 No.-

Pawley and Syder (1983) propose the concept of lexicalized sentence stems as “a unit of clause length or longer whose grammatical form and lexical content is wholly or largely fixed”(ibid: 191-192), and they conclude that native speakers rely much on stringing lexicalized sentence stems together for their fluent communication (ibid: 202). The concept of lexicalized sentence stems has values in phraseology; however, ‘lexicalization’ is not particularly operationalizable in empirical research, as corpus studies have shown that most phrasal units are only partially lexicalized (see Moon 1998: 37, etc.). Granger and Paquot(2008: 44) develop further the notion of lexicalized sentence stems and propose textual sentence stems. According to them (ibid: 44), textual sentence stems are routinized fragments ofsentences that serve textual functions, and a textual sentence stem typically involves a subject and a verb. Examples of textual sentence stems are the final point is, another thing is,it will be shown that andI will discuss. The concept of textual sentence stems lends itself more easily to empirical research than the lexicalized sentence stem in that it attaches more importance to functions of the sentence stem rather than its lexicalization. However, Granger and Paquot did not propose the practical methods and procedures for identifying textual sentence stems so defined, particularly in corpus-based studies. In addition, sentence stems, as the clause-level phraseological units, may perform such functions as the research-oriented function or participant-oriented function in Hylland’s term (2008:13-14), other than the textual or text-oriented function. And in some cases a sentence stems may perform multiple functions simultaneously. For these reasons, in the present research, we propose to opt for the term ‘functional sentence stem’ (henceforward FSS). This paper aims to explore common functional sentence stems in academic English texts, with a view to uncovering their typical forms and specific functions in context, in order to better inform ESP students of language resources with higher pedagogic utility. Functional sentence stems are temporarily defined as “An FSS is a recurrent contiguous lexico-grammatical sequence which contains a subject-predicate structure and which is associated with a particular function pertaining to a particular textual environment. The FSS may have a range of variations. ” The definition spells out several important defining features of the linguistic entity. Firstly a FSS consists of a subject-predicate structure, which makes it more compete in grammatical structure than the lexical bundle. For example, previous studies show that, data indicate that and it is not surprising that are all FSSs dealt with in the present study. Second, statistically, an FSS has to be significantly recurrent to ensure that it is a common means for meanings and functions. In the present study, only those FSSs whose frequencies have reached a frequency threshold of 10 or above and whose new-MI scores have reached 3.0 or above will be counted as a FSS. Thirdly, an FSS performs particular functions in association with co-occurring lexical and grammatical features in the local textual environment. And the functions can be of different types and nature, but most often a FSS is typically used to help organize textual information or to express the writer’s attitudinal or evaluative meanings. Fourthly, a FSS is usually not a fixed expression and it may have a range of varied forms. For instance, this paper describes may be varied to this paper discusses, the present paper examines, etc. We then use the new-MI measure (Wei & Li 2013) to extract from an academic English corpus a large number of FSSs, structural and functional characteristics of which are carefully examined and described in association with their co-selection patterns. Results indicate that FSSs are important means for a wide variety of specific discourse acts pertaining to characteristic local textual environments. The findings have potentially valuable implications for ESP pedagogy, offering, in particular, insights for improving non-native novice writers’ academic writing performance.

張靜杰 ( Zhang Jingjie ) 사단법인 아시아문화학술원 2020 인문사회 21 Vol.11 No.1

鲍照微言政治抒情诗继承发展了魏晋微言政治抒情诗,在隐喻、用典、改变古典细节等手法的基础上,还创造出假借、虚设人物形象、化用前人微言诗句等艺术手法。其内容主要是针对刘宋朝廷內衅,在高压的政治统治下,微婉其辞,揭露真相,体现了极高的微言艺术水平。本文对鲍照微言时事诗进行分析,既可以发掘刘宋朝廷时事,又能揭示诗人内心的政治良知和道德勇气;并探究鲍照微言诗的艺术特点及在诗歌创作上的地位和影响,具有文学和史学的双重价值。 BaoZhao’s WeiYan political lyric poetry inherited and developed the political lyric poetry of WeiJin dynasties. On the basis of metaphor, use of scripture, change of classical details and other techniques, he also created art techniques such as borrowing, pretending characters and using predecessors’ poetic poems. Its content is mainly aimed at the internal struggles of the Court of Liu Song Dynasty, under the political control of high voltage, speaking ambiguously, revealing the truth, embodies the rare art of high level. The analysis of BaoZhao’s poems on current affairs can not only reveal the current affairs of Liu Song court, but also reveal the poet’s inner political conscience and moral courage. It is of dual value of literature and history to explore the artistic characteristics of BaoZhao’s poems and their status and influence in poetic creation.
