What is an example of input control?

An example of input control is duplication checks. Input controls are designed to ensure the accuracy and completeness of data entered into a system. Duplication checks specifically focus on verifying that the data being entered does not duplicate existing records, which helps to maintain the integrity of the information within the system. By implementing duplication checks, organizations can prevent errors such as double entries that could lead to inaccurate reporting and analysis.

Data encryption and compliance checks, while important for data security and regulatory adherence, respectively, do not directly relate to the processes involved in ensuring the accuracy of data input. Similarly, access authorization pertains to controlling who can enter or modify data, but it does not involve the actual validation of the input data itself. Therefore, duplication checks stand out as a clear example of an input control focused on verifying the data as it is entered.
