    An Enhanced Model For Securing Password Authentication Using Typing Pattern
    (KNUST, 2018-06) Adjei-Twum Yeboah
    Data security is a critical concern for most organisations. Textual password is the commonest authentication system for verifying users though there are a number of well known vulnerabilities associated with it. The other alternatives like biometrics and graphical passwords also have their drawbacks. The aim of this study was to propose a scheme that provides another layer of security to textual password by using a typing pattern which does not require extra device. Therefore, making it cost effect. The cost of data breach is a universal concern and an area of importance for every modern organisation. Developing a scheme for enhancing password authentication, will improve the security of data therefore reducing data breach. Implementation of this scheme will provide security for users who lose their usernames and passwords since just the username and the password will not be able to log in a user. This scheme will reduce most of the attacks on textual password such as phishing, keylogging, brute force attacks, etc. The research questions that guided the study were, how can a model be developed to enhance the security of password authentication? And to what extent will user authentication model using typing pattern make password authentication more convenient and secure? Experiment method was used by the researchers to find answers to the research questions. 20 participants made up of equal number of novice and expert users representing the general populace of computer users were used in the study. The results of the study revealed a very low false rejection rate and false acceptance rate. The proposed scheme prototype demonstrated that the scheme is viable in practice and cost effective. The study also revealed that by using this model, users do not really need to pick a complex password that they might forget, but rather a good rhythm different from their natural typing rhythm that will be difficult to guess.
