There is a lack of timely access to necessary healthcare in remote areas, especially in India. This paper addresses the availability of quality healthcare, by introducing wireless technology to monitor patients, in remote areas. A reliable system to continuously monitor the patients in the remote areas has been developed, this software suite consists of two mobile software platforms. The first mobile software platform uses wearable wireless sensors to collect a Patient's ECG and Blood Pressure based on the patient's health condition. This sensed data is transmitted to the Patient's mobile phone where the first level of analysis is performed and an emergency warning may be indicated. If the patient's parameters are at a certain level a message is sent immediately to the Health Professional's mobile phone. The health data is also transmitted it to a central server for storage and further processing. This database can be of great value to health researchers. The second mobile software platform enables health professionals to view patient's health reports on their mobile phones from the central database. The health professional can also assign the risk levels of each patient, from the health professional's mobile phone. Both platforms communicate with the central database using a web server. This research also considers power optimization in the patient's mobile.

Passwords are the powerful tools that tend to keep all data and information digitally safe. It is frequently noticed that text password remains predominantly popular over the other formats of passwords, due to the fact that it is simple and expedient. However, text passwords are not always sturdy enough and are very easily stolen and misused under different vulnerabilities. Other persons can obtain a text password when a person creates a weak password or a password that is completely reused in many sites. In this condition if one password is hacked, it can be used for all the websites. This is called the Domino Effect. Another unsafe situation is when a person enters his/her password in a computer that is not trust-worthy; the password is prone to stealing attacks such as phishing, malware and key loggers etc. Among the most significant current threats to online banking are keylogging and phishing. These attacks extract user identity and account information to be used later for unauthorized access to user's financial accounts. This paper proposes a user authentication protocol which leverages a user's Android Smartphone and short message service to resist password stealing and password reuse attacks. This protocol only requires each participating website possesses a unique phone number and users only need to remember a long-term password for login on all websites. To provide more security to Android Smartphone, an additional method called color pattern screen locking is also proposed in this paper.Index Terms-Authentication, Password, Encryption and decryption, Network security, password reuse attack, password stealing attack.
