Abstract: Payroll services in banks are major sources of their revenue. Almost all the banks have moved to Core Banking and are offering payroll services to corporates. Corporates are utilising this service to a very great extend because of the advantages they offer to them. But now a days the scenario has changed. Wage related information is expected to be kept as a secret and hence the topic of concern is how effectively the payroll software maintain secrecy and ensure data integrity while preserving a secure channel for information interchange. This paper provides a hybrid algorithm for improving the payroll processing in banks which employ branch banking.
