Portable TOR Router with Raspberry Pi
Nowadays, internet has become an important part of everyone's lives. The internet has turned out to be a reliable tool for communication, data transfer and many more applications for people from all over the world. An individual's internet activities are being tracked and traced without their knowledge by various means. Thus, online security is a genuine worry for web clients who intend to visit interpersonal interaction locales, make an online transaction, or take an interest in internet diversions, as they need their protection to be ensured. Internet browsing is not anonymized as many Internet Service Providers (ISP's) could legally sell users information without informing users. People's internet activities are being tracked and traced by ISPs. Moreover, network spies and snooping attempts are very hard to be defeated as an ample network snooping tools are available in the market. These issues can be curbed by using a router that has anonymous browsing infrastructure. However, most of the routers that gives anonymous browsing are not portable. From this project, people will be able to browse anonymously without being traced. Besides that, network snooping and spying attempts can be defeated. Finally, a portable The Onion Routing (TOR) router can be created with a Raspberry Pi..
Application specific tunneling protocol selection for Virtual Private Networks
The application scope of VPN is increasing day by day as the organizations are creating private networks through public Internet using VPN tunneling instead of leased line. VPN protocols are classified into site-to-site and remote access VPN which exhibits different set of characteristics in terms of security mechanism. But there is no VPN preferences based on the organizational application requirements. In this paper, different VPN tunneling protocols like GRE, IPSec, PPTP and L2TP with IPSec are analyzed to measure the performance in terms of throughput, RTT, Jitter and security parameters. The results exhibits that, GRE is preferable for delay and bandwidth sensitive application in context of site to site VPN and L2TP is more effective than PPTP for remote access VPN.
An automated retinal image quality grading algorithm
This paper introduces an algorithm for the automated assessment of retinal fundus image quality grade. Retinal image quality grading assesses whether the quality of the image is sufficient to allow diagnostic procedures to be applied. Automated quality analysis is an important preprocessing step in algorithmic diagnosis, as it is necessary to ensure that images are sufficiently clear to allow pathologies to be visible. The algorithm is based on standard recommendations for quality analysis by human screeners, examining the clarity of retinal vessels within the macula region. An evaluation against a reference standard data-set is given; it is shown that the algorithm's performance correlates closely with that of clinicians manually grading image quality.
