In Information and telecommunication technology (ICT) has penetrated deep into the human lives and is affecting human life style in different aspects. The rapid growth in ICT has embarked improvement in computing devices and computing techniques. Currently cloud computing is one of the most hyped innovation. It has several positive impacts like reduced cost, increased throughput, ease of use but it also had certain security issues that must be dealt with carefully. There are several techniques that can be used to overcome this major problem. In this paper we will analyse biometric authentication in cloud computing, it's various techniques and how they are helpful in reducing the security threats. It provides a comprehensive and structured overview of biometric authentication for enhancing cloud security.

Information and telecommunication technology (ICT) has penetrated deep into the human lives and is affecting human life style in different aspects. The rapid growth in ICT has embarked improvement in computing devices simultaneously decreasing product life and resulting in e-waste. This study examines various issues and challenges being faced by different countries in e-waste management. We will analyse what the legislations for e-waste management are and how they should be implemented in order to eliminate this issue.

Objective: To explore sex differences in cardiovascular disease (CVD) related risk factors such as diabetes, hypertension, and demographic, anthropometric, biochemical, clinical, and nutritional differences among 40-60 years old Pakistani CVD patients.Design: This was a cross-sectional, descriptive study.Setting: The present study was conducted at the Mayo/King Edward Medical University (K.E.M.U) Hospital Cardiology Department (CCU-I & CCU-II), Lahore, from February 2020 to June 2020. A self-administered questionnaire was used for data collection.Participants: A random sample of 300 cardiac patients was included in the study. Patient records, food frequency questionnaire and 24-hour dietary recall was used to solicit information about demographic, anthropometric, biochemical, and clinical measurements; dietary intake parameters; and CVD risk factors such as hypercholesterolemia, hypertension, diabetes, and smoking. Results: Men CVD patients had higher BMI (33.43 kg/m2 vs. 28.69 kg/m2) and higher prevalence of hypertension (81.1% vs. 59%), hypercholesterolemia (82.4% vs. 54.5%) and smoked more cigarettes (72.6% vs. 9%) as compared to women while there was higher prevalence of diabetes among women as compared to men (59% vs. 29.4%). There were 85% women vs. 80% men consuming white bread, while half of the men reported using meat daily, as compared to only 16.6% women. There were 51.5% women and 17% men who reported consuming fruits and vegetables daily. There were 40% men and 16% women who reported consuming soft drinks. Conclusion: The study showed significant sex differences in the nutritional status and risk factors of patients with CVD.
