Most organizations use one form of online registration or another. Since these registration forms are structured to be open and available to users, many of them do not afford or seem to require basic security measures like access control measures or even basic passwords. This however implies that the authenticity of the user, and accountability of the user to the information provided is not established, thereby making repudiation a possibility. This work proposes a strategy to reduce deniability on the part of the users of e-registration systems, and strengthen accountability using a digital signature based field locking process. The work used students’ registration liberally as the focal point and will encourage users to take more seriously the data they fill into online forms just like they do in paper based ones.
