SecureShuffle

This algorithm masks by shuffling the values is a particular field or column to different lines or rows. For example, values for the FIRST_NAME column might be shuffled among a number database rows within a table. It guarantees that each value is moved to a different line or row, but will not prevent an input from masking to the same output in the case where the values shuffled are not unique.

Because shuffling data does not redact or modify the individual data values in any way, careful consideration must be given to whether this form of obfuscation is sufficient to meet your security requirements.

The SecureShuffle algorithm may only be used with masking jobs that support batching, and will not be presented as an option in the inventory screen when it is not supported. The maximum number positions any particular value will be moved within the input is equal to the batch size.

Please refer to the Batch Masking section here for a full description of the Batch Masking mechanism, as well as details on batch size and which jobs support batching.

This algorithm will report non-conformant data whenever only one value is available to mask, meaning that no shuffling is possible.
