Anonymous and confidential communication using PDAsMolina-Jimenez, Carlos January 2000 (has links)
Anonymizers based on an intermediate computer (a set of them) located between the sender and the receiver of an e-mail message have been used for several years by senders of e-mail messages who do not wish to disclose their identity to the receivers. The job of the computer in the middle (the mediator) is to receive the message from the sender, delete the sender's address and other personal data from the header of the message, and forward the message to its final destination. In this paradigm, there are no means to hide the identity of the user from the mediator simple because the message sent arrives in the middle computer, with information that easily leads to the identity of the sender. The origin of this problem is that the sender uses a computer identified by an IP-address that unambiguously leads to the identity of its user. In fact, the sender discloses his identity to the mediator computer from the very moment lie sends his message in the hope that the mediator will protect it. Because of this, in this paradigm the strength of the system for protecting the identity of the sender depends on the ability and willingness of the mediator to keep the secret. In this dissertation we propose a novel approach to sending truly anonymous and confidential messages over the Internet which does not depend on a third party. Our idea departs from the mediator approach in that we do not use an IP-addressed computer to send anonymous messages, we use an IP-addressless computer instead, to be specific, we use a Personal Digital Assistant (PDA) which is IP-addresslessly connected to the Internet with the support of a Mobile Support Station (MSS). The PDA is identified by the MSS by a temporary, non-personal, random identifier (TmpId) which is assigned by the MSS and is valid only for one communication session. Thanks to the use of the TmpId, the sender of the anonymous messages does not need to disclose his identity to the MSS or to anybody else; thus, the strength of the system does not depend on any mediator. Having observed that a public telephone box provides complete anonymity when operated by coins, we took its functionality as a paradigm for our system. Thus, the main idea of our approach is to make the PDA, the MSS, and the Internet communication infrastructure imitate the work of a public telephone box connected to the telephone network. For this to be possible the PDA user uses anonymous electronic cash to pay for his anonymous message. To prove the feasibility of our approach and its correctness, the protocol of the proposed system was designed, specified in Promela specification language, and its basic safety properties and proper end-states were validated using the Spin validator.

The Usage of Smartphone and PDA Based Electronic Drug Databases Among PharmacistsBluder, Steven January 2012 (has links)
Class of 2012 Abstract / Specific Aims: To assess the use of PDA/smartphone based electronic drug databases among pharmacists as it has changed over time. The working hypothesis is that the use of PDA/Smartphone based electronic drug databases has increased over time.
Methods: A systematic review of the literature regarding the usage of PDA/smartphone based electronic drug databases among pharmacists using data that was obtained through literature searches.
Main Results: Since 2006, the percentage of pharmacists that are using PDA/smartphone based electronic drug databases has increased. Conclusions: The usage of smartphones and PDA based electronic drug databases has increased among pharmacists since 2006 (p<0.05). Easier and cheaper access to the technology has likely led to the products being available to more pharmacists.

Examining the Role of Purpose in the Adoption of Digital AssistantsNathanael Johnson (8797193) 04 May 2020 (has links)
When do consumers adopt digital
personal assistants like Cortana, Siri, or Alexa? This thesis proposes to add
to the current technology adoption literature on digital assistants by
examining the moderating impact of the purpose for which the device is used.
Building on the theory of uses and gratifications, it was expected that devices
viewed with high cognitive appraisal would be more likely to be chosen for
cognitive purposes than devices viewed with high affective appraisal, while
devices viewed with high affective appraisal would be more likely to be
selected for affective purposes than devices viewed with high cognitive
appraisal. Two experiments were conducted that supported these hypotheses.
