Hence CAPTCHAs are used for making systems more secure. The major role of CAPTCHA is to prevent robotic bot (spam) form surrender or prove user personality. Using a pattern-matching algorithm is necessary for the user for comparison by receiving signs founded in similar matches. This method makes it difficult to get a forbidden access to data, since malicious bot is to spy out signs in the image. This mechanism implements actions on the attitude of user gesticulation which makes it distinguishable and secure. Human-Computer Interaction i.e. interaction between computer and individual is made to make it easy in understand human language .On other words, Human-computer Interaction focuses on the study of interfaces between computer and human. This paper presents a comprehensive study of various different types of CAPTCHA, the ones good in securing webpages. It also discusses the strengths and weaknesses of each one. Moreover, its importance in discerning the user's individuality, the behavior of humans, and bots and the paper will illustrate some CAPTCHAs mechaniits and impairments which allows hackers to break .In addition, is necessary to take into consideration the approaches of building a good CAPTCHA.

This deviation typically results from the changes that happed and the project manager depends on his experience to estimate the effects of the change. This may affect the duration and budget of the project. It is important that the software project should not deviate or crash according to the estimated deadline. Thus any change should be estimated and discussed before implementation. In this paper will introduce a framework that integrates the Software Project Management (SPM) with Software Change Management (SCM) to achieve the following objectives: Firstly, optimizing the Change Management Process in a project and track the whole Change Requests. Secondly, monitoring if the software project finished early by revising the project plan w.r.t the actual schedule to shrink the project deadline. And execute the consequences processes according to finish early. Thirdly, the actual results with performance will be tracked against the project plan and any variances should be analyzed. In addition, facilitating distribution of tasks (Change Requests) and availability of information. Finally, providing more control over a project when the technical issues can be raised and turned to
