Data Redaction Options for Data Elements

Data redaction is the process of obscuring or removing information from a data result prior to displaying the result. ALDSP 3.2 offers the following forms of data redaction for secured elements and attributes:

• Optional elements and attributes may be omitted from the result
• Simple-typed elements and attributes may have their values substituted by a fixed, default value in the result
• String-valued elements and attributes may have their values encrypted using a secure, identity-preserving transformation

The first two forms map originally distinct fields in multiple data instances to the same redacted representation. This means that these methods are not suitable for certain applications, such as data analytics, which require that fields maintain their identity so that standard operations such as GroupBy or Join can be performed based on the fields.

The third form, encrypting the data, preserves the identity of the field enabling you to perform a wider range of operations on the data. ALDSP 3.2 offers secure encryption-based data redaction that you can use to encrypt elements in the results of read and navigate functions declared in entity data services.

See Data Redaction Conditions for details about the conditions and availability of ALDSP 3.2 data redaction options.
