Image Processing of Two Identical and Similar Photos

This paper aims to find  the differences between two perfect identical and similar  photos using image processing principles, the method depends on constructing the histogram of the two images and using what is called image registration,  and also  using Matlab image processing system with suitable code the system can easily discover the main difference points between the two images. This technique  helps in medical applications: in surgery and bones x-ray images. Keywords: image-processing, photos, Matlab, histogram, medical applications

Distribution Systems Efficiency

This paper constructing a measurement system for determining the efficiency of the distributed system. This efficiency depends on many parameters like number of terminals, number of customers and kind of information, number of nodes, and number of messages. It is found that the efficiency depends strongly on number of messages sent or received inside the distributed system, as the number of messages increased the efficiency decreased. Keywords: distributed system, terminals, efficiency

Review and Measuring the Efficiency of SQL Injection Method in Preventing E-Mail Hacking

E-mail hackers use many methods in their work, in this article, most of such efficient methods are demonstrated and compared. Different methods and stages of such methods are listed here, in order to reveal such methods and to take care of them but the most common discussed method in this paper is SQL method. SQL injection is a type of security exploit in which the attacker adds SQL statements through a web application’s input fields or hidden parameters to gain access to resources or make changes to data. It is found that the SQL is an efficient way in preventing E-mail hacking and its efficiency reaches about 80%. The method of SQL injection can be considered as an efficient way comparing with other methods
