Additional date formats to be considered during date obfuscation. This allows users to specify custom date formats in addition to the default dateFormats.

List of integers specifying limits of the age groups to preserve during obfuscation

A Boolean variable indicating whether to obfuscate ages based on HIPAA (Health Insurance Portability and Accountability Act) Privacy Rule.

The HIPAA Privacy Rule mandates that ages from patients older than 90 years must be obfuscated, while age for patients 90 years or younger can remain unchanged.

When true, age entities larger than 90 will be obfuscated as per HIPAA Privacy Rule, the others will remain unchanged. When false, ageRanges parameter is valid.

Param that indicates whether consistency should be enforced across different parts of a name (e.g., first name, middle name, last name). When set to true, the same transformation or obfuscation will be applied consistently to all parts of the same name entity, even if those parts appear separately.

For example, if "John Smith" is obfuscated as "Liam Brown", then:

• When the full name "John Smith" appears, it will be replaced with "Liam Brown"
• When "John" or "Smith" appear individually, they will still be obfuscated as "Liam" and "Brown" respectively, ensuring consistency in name transformation.

Default: true

Whether to obfuscate country entities or not. If true, country entities will be obfuscated using the Faker module. If false, country entities will be skipped during obfuscation. Default: false

The dictionary of custom fakers to specify the obfuscation terms for the entities. You can specify the entity and the terms to be used for obfuscation.

List of date entities. Default: Array("DATE", "DOB", "DOD", "EFFDATE", "FISCAL_YEAR")

Format of dates to displace

Number of days to obfuscate the dates by displacement. If not provided a random integer between 1 and 60 will be used

Whether to enable default obfuscation equivalents for common entities. This parameter allows the system to automatically include a set of predefined common English name equivalents. Default: false

It specifies how much length deviation is accepted in obfuscation, with keepTextSizeForObfuscation enabled. Value must be greater than 0. Default is 3.

Select the fixed mask length: this is the length of the masking sequence that will be used when the 'fixed_length_chars' masking policy is selected.

Whether to use gender-aware names or not during obfuscation. This param effects only names. If value is true, it might decrease performance. Default: False

Whether to enforce consistent obfuscation across geographical entities: state, city, street, zip and phone.

## Functionality Overview This parameter enables intelligent geographical entity obfuscation that maintains realistic relationships between different geographic components. When enabled, the system ensures that obfuscated addresses form coherent, valid combinations rather than random replacements.

## Supported Entity Types The following geographical entities are processed with priority order: - **state** (Priority: 0) - US state names - **city** (Priority: 1) - City names - **zip** (Priority: 2) - Zip codes - **street** (Priority: 3) - Street addresses - **phone** (Priority: 4) - Phone numbers

## Language Requirement **IMPORTANT**: Geographic consistency is only applied when: - geoConsistency parameter is set to true AND - language parameter is set to en

For non-English configurations, this feature is automatically disabled regardless of the parameter setting.

## Consistency Algorithm When geographical entities comes from the chunk columns:

1. **Entity Grouping**: All geographic entities are identified and grouped by type 2. **Fake Address Selection**: A consistent set of fake US addresses is selected using hash-based deterministic selection to ensure reproducibility 3. **Priority-Based Mapping**: Entities are mapped to fake addresses following the priority order (state → city → zip → street → phone) 4. **Consistent Replacement**: All entities of the same type within a document use the same fake address pool, maintaining geographical coherence

## Parameter Interactions **IMPORTANT**: Enabling this parameter automatically disables: - keepTextSizeForObfuscation - Text size preservation is not maintained - consistentObfuscation - Standard consistency rules are overridden - file-based fakers

This is necessary because geographic consistency requires specific fake address selection that may not preserve original text lengths or follow standard obfuscation patterns.

It specifies whether the output should maintain the same character length as the input text. the output text will remain the same if same length is available, else length might vary.

Select the masking policy:

• 'entity_labels': Replace the values with the entity value.
• 'same_length_chars': Replace the name with the asterix with same length minus two plus brackets on both end.If the entity is less than 3 chars (like Jo, or 5), we can just use asterix without brackets.
• 'fixed_length_chars': Replace the obfuscated entity with a masking sequence composed of a fixed number of asterisk.
• 'entity_labels_without_brackets': Replace the values with the entity value without brackets.
• 'same_length_chars_without_brackets': Replace the name with the asterix with same length without brackets.
• Default: 'entity_labels'

Mode for Anonymizer ['mask' or 'obfuscate']. Default: 'mask'

• Mask mode: The entities will be replaced by their entity types.
• Obfuscate mode: The entity is replaced by an obfuscator's term.

When mode=="obfuscate" whether to obfuscate dates or not. This param helps in consistency to make dateFormats more visible. When setting to true, make sure dateFormats param fits the needs. If the value is true and obfuscation is failed, then unnormalizedDateMode will be activated. When setting to 'false', then the date will be masked to <DATE>. Default: false

The source of obfuscation to obfuscate the entities. The values ar the following: 'file': Takes the entities from the obfuscatorRefFile 'faker': Takes the entities from the Faker module 'both': Takes the entities from the obfuscatorRefFile and the faker module randomly.

variant-to-canonical entity mappings to ensure consistent obfuscation.

This method allows you to define equivalence rules for entity variants that should be obfuscated the same way. For example, the names "Alex" and "Alexander" will always be mapped to the same obfuscated value if they are linked to the same canonical form.

It accepts an array of string triplets, where each triplet defines:

• variant: A non-standard, short, or alternative form of a value (e.g., "Alex")
• entityType: The type of the entity (e.g., "NAME", "STATE", "COUNTRY")
• canonical: The standardized form all variants map to (e.g., "Alexander")

variant and entityType comparisons are case-insensitive during processing.

This is especially useful in de-identification tasks to ensure consistent replacement of semantically identical values. It also allows cross-variant normalization across different occurrences of sensitive data.

With this property, you can select particular dateFormats. This property is especially used when obfuscating dates. You can decide whether the first part of 11/11/2023 is a day or the second part is a day when obfuscating dates.

• The values are following:
• 'eu' for European Union
• 'us' for USA

List of formatted entities to generate the same length outputs as original ones during obfuscation. The supported and default formatted entities are: "phone", "fax", "contact," "id", "idnum", "bioid", "medicalrecord", "zip", "vin", "ssn", "dln", "plate", "license", "IRS", "CFN", "account".

It is the seed to select the entities on obfuscate mode. With the seed, you can reply to an execution several times with the same output.

A map of entity names to their obfuscation modes. This is used to selectively apply different obfuscation methods to specific entities. The keys are entity names and the values are the obfuscation sources. If an entity is not specified in this map, the obfuscateRefSource param is used to determine the obfuscation source.

The dictionary of modes to enable multi-mode deidentification.

• 'obfuscate': Replace the values with random values.
• 'mask_same_length_chars': Replace the name with the asterix with same length minus two plus brackets on both end.
• 'mask_entity_labels': Replace the values with the entity value.

• 'mask_entity_labels_without_brackets': Replace the values with the entity value without brackets.
• 'mask_same_length_chars_without_brackets': Replace the name with the asterix with same length without brackets.
