Color Cipher Scheme based ATM Pin Generation and Verification

Use of plastic money is very easy but few understand the security issues running behind the atm machine and connected networks. This paper drawls to easy maintenance of pin generation, authentication and verification techniques. Depending upon colour scheme and supportive scheme, user has to respond to random challenge thrown and accordingly this system will work. Ease of remembering and mandatorily changing passwords and pins for subsequent times have also been addressed without decreasing difficulty level of cracking it. There are several techniques which have been used for quite long. Lack of awareness of security issues and obsolete techniques being used for secure transformation of pin, makes it very essential to instil. There have been constant efforts on creation of system that would provide ease at the user end and very difficult for the illegitimate user to crack it. For the purpose of governance, computational time and storage are the vital factors.
