Abstract

In the proposed search, new technique for calculating the similarity among parts related to iris images for the selected person and among iris images will be suggested by dividing iris texture into pre decided number of parts and calculating some features of each one of these parts as a texture then calculating degree of similarity among specific part and all other parts of the same iris and with some irises in database according to some accepted rules. The proposed method divided iris texture into eight parts with (45 degrees) for each part, the features of GLCM algorithm will be calculated for parts of iris image then the distance or similarity between specific and required iris with other irises that will be stored in database will be calculated and finally, the similarity calculated between each part (with 45 degrees) of iris and parts of irises stored in database. The proposed system applied some suitable techniques for localized the pupil of the iris image by using watershed segmentation method by drawing arrows between each pixels and 8-nighbouring pixels according to occurrence of some suitable feature then deleting all arrows from selected pixels if another feature doesn’t available in this pixels, this proposed system used for reducing database size for each registered person depending on extracted features from some parts of another person or from extracted features from one part of iris image.

Abstract

This study proposes a measurable scale to gauge advertising effectiveness of digital signage. Gender study was performed on the constructs to supplement the findings. “Engagement” and “Involvement”, two well-known constructs were used to find out the advertising effectiveness using digital signage. A real-time experiment was conducted and the survey data (N = 221) were analysed, presenting descriptive analysis and T-test analysis across all items among the constructs. The findings reveal that both “Engagement” and “Involvement” are significant contributors to advertising effectiveness in the context of digital signage. Findings also suggest that females tend to enjoy the advertisements more with higher degree of advertisement related experiences.

Abstract

New credit cards containing Europay, MasterCard and Visa (EMV) chips for enhanced security, and for in-store purchases (rather than online purchases) have been adopted considerably in recent years. EMV supposedly protects the payment cards in such a way that the computer chips in a card referred to as chip-and-pin cards generate a unique one-time code each time the card is used.  The one-time code is designed such that if it is copied or stolen from the merchant system or from the system terminal, it cannot be useful for creating a counterfeit copy of that card or counterfeit chip of the transaction. However, in spite of this design, EMV technology is not entirely foolproof from failure. This paper dis-cusses the issues, failures and fraudulent cases associated with EMV Chip-And-Card technology. The work also evaluates people’s understanding of these issues and the consequential precautions they take to safeguard their information while using the EMV cards for transactions.
