Abstract: The act of developing secure program modules assist software owners to reduce maintenance cost and increase dependency on the software. Frequent attacks by hackers are mostly aim at corrupting data to undermine software reliability and distort input integrity. Inappropriate data can even result to denial of service to software users if such data crashes the system. In this research the use of secure program development approach will be deployed to generate reliable data for student registration in tertiary institutions. The data is transformed using object oriented approach (OOP) in conformity with software development using modular approach. OOP class construct, decision structure, loop, inheritance and interface will be employed to build the module. The interface is implemented to make sure there is conformity with the data specification. The program will ensure data such as name of student, level, matric number, department, age and grade point average (GPA) pass through a carefully formulated system that will ensure that these data conformed to required data laid down guidelines and conforms to format. This result from the module shows an output of range of references displaying either valid or invalid data depending on if either all the set of input data are either completely conforms to format or not. The module can be adopted by developers for a range of data checking activities during operations; it will also assist programmers to identify permissible data set for a given operation. A graphical interface for the module can be developed and then integrated as data integrity check in applications.
