Inferring Mobile Payment Passcodes Leveraging Wearable Devices

Mobile payment has drawn considerable attention due to its convenience of paying via personal mobile devices at anytime and anywhere, and passcodes (i.e., PINs) are the first choice of most consumers to authorize the payment. This work demonstrates a serious security breach and aims to raise the awareness of the public that the passcodes for authorizing transactions in mobile payments can be leaked by exploiting the embedded sensors in wearable devices (e.g., smartwatches). We present a passcode inference system, which examines to what extent the user's PIN during mobile payment could be revealed from a single wrist-worn wearable device under different input scenarios involving either two hands or a single hand. Extensive experiments with 15 volunteers demonstrate that an adversary is able to recover a user's PIN with high success rate within 5 tries under various input scenarios

Attraction of Spiral Waves by Localized Inhomogeneities with Small-World Connections in Excitable Media

Trapping and un-trapping of spiral tips in a two-dimensional homogeneous excitable medium with local small-world connections is studied by numerical simulation. In a homogeneous medium which can be simulated with a lattice of regular neighborhood connections, the spiral wave is in the meandering regime. When changing the topology of a small region from regular connections to small-world connections, the tip of a spiral waves is attracted by the small-world region, where the average path length declines with the introduction of long distant connections. The "trapped" phenomenon also occurs in regular lattices where the diffusion coefficient of the small region is increased. The above results can be explained by the eikonal equation and the relation between core radius and diffusion coefficient.Comment: 5 pages, 4 figure

The Effective Spreading of Soft Power in Chinese Culture

The cultural soft power is the core of power which determines the existence of a national legality and rationality. To form the incommensurability and dialogicality between a country’s culture and other civilizations, we must strengthen the ability to spread culture effectively. The core of spreading cultural soft power is to achieve the identity of extrinsic and intrinsic collective culture. At present ,the spreading of Chinese culture still remains, to a certain degree, in a state of dislocation. In order to achieve cultural identity, certain power and value identity should be achieved first. This paper aims at exploring the above issue based on the analysis of the current situation of Chinese culture spreading and its soft power.Key words: Cultural soft power; Cultural transmission; Value identit

Existence of multiple solutions for a p(x)- biharmonic equation

The aim of this paper is to obtain at least three solutions for a Neumann problem involving the p(x)-biharmonic operator. The main tool used for obtaining our result is a three critical points theorem established by Ricceri

Chinese Culture Communication Approaches: Intercultural Hermeneutics

Our culture has been in a serious “Aphasia” state for many years on the world stage. We cannot have our voices and to express ourselves freely because of different understanding. Intercultural hermeneutics can seek and utilize the advantages of core value in Chinese culture to spread internationally in the world and culture promotion, which will be developed with the help of intercultural hermeneutics finally, and to improve cultural innovation to form a core value

Characteristic Analysis of Mandarin Chinese From a Cultural Perspective

The linguistic study of Mandarin Chinese has added new dimension of language research and enriched linguistic theories. Mandarin Chinese displays a number of typologically salient features which is the manifestation of Chinese culture. Chinese empirical synthesis thinking pattern emphasize in changing, recognition of contradiction and the need for multiple perspectives and rely on experience-based knowledge. Western thinking pattern takes logic and formal testimony is the chief concern and concepts. Thus judgment and reasoning dominate the thinking procedures. Culture and mode of thinking permeates in all aspects of the social practice and contributed the diversity of languages. This paper analyzes the features of Mandarin Chinese in three levels from a cultural perspective. The most important characteristic of Chinese is that it is a parataxis language by contrast of English as a hypo taxis language
