A Secure RFID Tag Authentication Protocol with Privacy Preserving in Telecare Medicine Information System

Abstract: Radio Frequency Identification (RFID) based solutions are widely used for providing many healthcare applications include patient monitoring, object traceability, drug administration system and telecare medicine information system (TMIS) etc. In order to reduce malpractices and ensure patient privacy, in 2015, Srivastava et al. proposed a hash based RFID tag authentication protocol in TMIS. Their protocol uses lightweight hash operation and synchronized secret value shared between back-end server and tag, which is more secure and efficient than other related RFID authentication protocols. Unfortunately, in this paper, we demonstrate that Srivastava et al.'s tag authentication protocol has a serious security problem in that an adversary may use the stolen/lost reader to connect to the medical back-end server that store information associated with tagged objects and this privacy damage causing the adversary could reveal medical data obtained from stolen/lost readers in a malicious way. Therefore, we propose a secure and efficient RFID tag authentication protocol to overcome security flaws and improve the system efficiency. Compared with Srivastava et al.'s protocol, the proposed protocol not only inherits the advantages of Srivastava et al.'s authentication protocol for TMIS but also provides better security with high system efficiency.

Are Taiwanese individual investors reluctant to realize their losses

Abstract: Taiwanese investors exhibit a stronger disposition effect than US investors. On average, the proportion for realizing gains is 2.5 times that for realizing losses. The corresponding multiple for the US investors is 1.5 [Odean, T., 1998. Are investors reluctant to realize their losses? Journal of Finance 53, 1775–1798.]. The cultural difference between the Ease and the West could partly explain this phenomenon, i.e., Taiwanese investors have stronger beliefs in mean reversion than US investors. However, investors' belief formation is not obviously reinforced by their experiences from the stock market. Analysis at the stock characteristic level finds that investors trading stocks in high-return/low-price categories and in low-return/high-price categories exhibit the reverse disposition effect. The disposition effect at the individual level shows that aged female investors are more inclined to asymmetrically deal with their gains than losses. By contrast, the investors with margin trading are less likely to exhibit the disposition effect.

Use of CHADS2 and CHA2DS2-VASc Scores to Predict Subsequent Myocardial Infarction, Stroke, and Death in Patients with Acute Coronary Syndrome: Data from Taiwan Acute Coronary Syndrome Full Spectrum Registry

Abstract: Background Acute coronary syndrome (ACS) patients have a wide spectrum of risks for subsequent cardiovascular events and death. However, there is no simple, convenience scoring system to identify risk of adverse outcomes. We investigated whether CHADS2 and CHA2DS2-VASc scores were useful tools to assess the risk for adverse events among ACS patients.
