Telemedicine applications are more and more used due to the rapid development of digital imaging and information and communication technologies. Medical information which include digital medical images and patient’s information are extracted and transmitted over insecure networks for clinical diagnosis and treatments. Digital watermarking is one of the main approaches used to ensure the security of medical images. Nevertheless, in some cases, the only use of digital watermarking is not sufficient to reach a high level of security. Indeed, the watermark could carry essential patient information and needs to be protected. In such cases, cryptography may be used to protect the watermark and to improve the overall secured management in the medical environment. In this paper, we propose a clone-resistant watermarking approach combining a difference expansion watermarking technique with a cryptographic technique based on secret keys generated by a clone-resistant device called Secret Unknown Ciphers (SUCs). The use of SUCs to sign the watermark enforces the security of medical images during their transfer and storage. Experimental results show that the system provides a high level of security against various forms of attacks.

AbstractThe rapid development of information and communication technologies (ICTs) and the high level of consumer acceptance have made it increasingly complex to retain loyal customers. Virtual Reality (VR) has become a solution that allows tourism providers to design technology-enhanced experiences along the entire customer journey. While most VR offers focus on pre-travel experiences, the potential of VR in the post-travel phase is still little explored. Considering that multisensory tourism experiences contribute to memory formation, the multisensory extension of VR (4D VR) in post-travel experiences is of interest. Thus, through a quantitative field experiment, this study aims to detect what effect the stimulation of different senses during the use of VR has on the overall experience and how this influences the brand relationship quality. The results revealed elevated levels of technology acceptance, which consequently enhances the traveler’s overall VR experience. The multisensory component positively affects one realm of an experience in the area of escapism and thus correlates with the overall experience. However, there is no significant difference between 3D and 4D regarding the level of brand relationship quality. The study expands the literature on 4D VR experiences and supports tourism practitioners in the implementation to strengthen the relationship between a destination and its guests.

Developments in information and communication technologies have raised the issue of the intergenerational digital divide that can take place between “digital natives” and “digital immigrants”. Despite emphatic claims concerning how educational systems must take into account the specific characteristics of “digital natives”, sound empirical research on these topics is lacking, especially for Europe. This paper presents the results of research performed during the course of 2008, studying how university students in Italy use digital technologies. The research is based on a survey of 1086 undergraduate students at the University of Milan-Bicocca, complemented by focus groups and in-depth interviews. The results of our research show that, even if university students are familiar with digital technologies, the general possession of high level skills in accessing and using the Internet should not be taken for granted.

Conceptual foundations of organizational and economic support for the development of enterprises in the hospitality industry have been developed, taking into account the level of use of information and communication technologies. It has been determined that the main results of the influence of information technologies on the hospitality industry are the optimization of business processes, as well as the transformation of the target consumer of hospitality services. The types of information and communication technologies are systematized depending on the direction of the business processes of the cycle of providing hospitality services. It has been substantiated that through the active use of information and communication technologies, hospitality industry enterprises satisfy the needs of customers in full in accordance with modern requirements. The relationship was established between the results of assessing the level of organizational and economic support for the development of information and communication technologies and the strategic choice of enterprises in the hospitality industry. Three types of strategies are identified – information expansion, improvement, retention and further development – depending on the low, medium and high level of development of information and communication technologies, respectively. The directions of increasing the level of development of information and communication technologies of the hospitality industry at different levels are proposed. The developed theoretical and methodological provisions can be useful in the formation of the concept of strategic development of the hospitality industry. The use of the proposed toolkit reflects the results, both quantitatively (increasing demand for hospitality services, improving financial performance, etc.) and in a qualitative form (improving the quality of service, creating a positive image, etc.).

General Concern

As the use of Information and Communication Technologies (ICTs) increases in Zambia, there is a general concern about whether the use and eventual disposal of ICT hardware will have minimal impact on the environment. The grooming or modification of behavior of users for the future generation takes place in educational institutions. This paper therefore explored the level of use of ICTs in Higher Educational Institutions (HEIs) with regard to the awareness and adoption of green computing in these institutions. The results indicated that though there is a high level of use in the HEIs, the level of green computing awareness was simply moderate and the level of green computing adoption was low. Therefore, there is need for HEIs, the IT community and the legislative bodies to do more in introducing practices that will promote eco-friendly use and disposal of ICTs in Zambia.
