People need more security to protect their resources like money, documents, jewels etc. but they cannot often to go and use bank lockers every day. So they need a security system in their home to protect those resources. Password that uses text or string of characters such as their names, date of birth are more vulnerable to guess and can be easily cracked. They cannot go for bio-metrics too, as they are costly for middle class people. Our project deals with the processing of colour based passwords to give as pattern for their security reasons, which can be defined by them. This paper will conclude that our project will provide security system for ordinary people and illiterates.
