Google Cloud Data Loss Prevention v2 API - Class CharacterMaskConfig (4.6.0) 

public sealed class CharacterMaskConfig : IMessage<CharacterMaskConfig>, IEquatable<CharacterMaskConfig>, IDeepCloneable<CharacterMaskConfig>, IBufferMessage, IMessage

Reference documentation and code samples for the Google Cloud Data Loss Prevention v2 API class CharacterMaskConfig.

Partially mask a string by replacing a given number of characters with a fixed character. Masking can start from the beginning or end of the string. This can be used on data of any type (numbers, longs, and so on) and when de-identifying structured data we'll attempt to preserve the original data's type. (This allows you to take a long like 123 and modify it to a string like **3.

Properties

CharactersToIgnore

public RepeatedField<CharsToIgnore> CharactersToIgnore { get; }

When masking a string, items in this list will be skipped when replacing characters. For example, if the input string is 555-555-5555 and you instruct Cloud DLP to skip - and mask 5 characters with *, Cloud DLP returns ***-**5-5555.

Property Value
TypeDescription
RepeatedFieldCharsToIgnore

MaskingCharacter

public string MaskingCharacter { get; set; }

Character to use to mask the sensitive values&mdash;for example, * for an alphabetic string such as a name, or 0 for a numeric string such as ZIP code or credit card number. This string must have a length of 1. If not supplied, this value defaults to * for strings, and 0 for digits.

Property Value
TypeDescription
string

NumberToMask

public int NumberToMask { get; set; }

Number of characters to mask. If not set, all matching chars will be masked. Skipped characters do not count towards this tally.

If number_to_mask is negative, this denotes inverse masking. Cloud DLP masks all but a number of characters. For example, suppose you have the following values:

  • masking_character is *
  • number_to_mask is -4
  • reverse_order is false
  • CharsToIgnore includes -
  • Input string is 1234-5678-9012-3456

The resulting de-identified string is ****-****-****-3456. Cloud DLP masks all but the last four characters. If reverse_order is true, all but the first four characters are masked as 1234-****-****-****.

Property Value
TypeDescription
int

ReverseOrder

public bool ReverseOrder { get; set; }

Mask characters in reverse order. For example, if masking_character is 0, number_to_mask is 14, and reverse_order is false, then the input string 1234-5678-9012-3456 is masked as 00000000000000-3456. If masking_character is *, number_to_mask is 3, and reverse_order is true, then the string 12345 is masked as 12***.
