ABSTRACT:
In a computer-based information system where verification of transmitted data is performed, a method is disclosed for verifying validity of transmission data based on a numerical identifier for the transmission data. The method includes generating a first number based on the transmission data and obtaining a numerical identifier for the transmission data. The method further includes generating a second number from the first number and the numerical identifier, and verifying the validity of the transmission data based on the second number. In this way, based on the numerical identifier included in the transmission data, it can be verified if a recipient of the transmission data is the intended recipient and/or if the transmission data is validly attempting to access a data structure.
