Create a data privacy technique configuration to customize how data privacy anonymizes your data.

## Vorbereitungen

Role required: data_privacy_admin and admin

## Prozedur

1. Elevate to the data_privacy_admin role.  
   For details on role elevation, see [Elevate to a privileged role](https://servicenow-prod.fluidtopics.net/QSMW4UNBg6bevZDKAPGT2Q "The base system admin can elevate to a privileged role to have access to the features of High Security Settings.").
2. Navigate to System SecurityData PrivacyAnonymization.
3. Select View techniques.  
   There are several pre-defined techniques available for selection.  
   {#dps-create-anonymization-techniques__entry__2}

   | Technique | Description |
   |-|-|
   | Selective Replace | This technique does a selective replace of String data. All characters between the input's start and end indices are replaced with the character you choose. You can specify characters to exclude from masking: * start_index: Technique masks data starting at the specified character. If left blank, masking begins with the first character. * end_index: Technique masks data from the start of the string to the specified character. If left blank, masking ends with the last character. * exclude_char: Define a character to exclude from masking. * replacement_char: Define a character used for masking. If none is provided, asterisks(\*) are used by default. {#dps-create-anonymization-techniques__ul_ubr_v1w_4tb} |
   | Static Replace | This technique swaps values with static values. String, Number, and Date data can use this technique: * date_time_value: Replace Date values with this date. Use the yyyy-MM-dd HH:mm:ss format. * date_value: Replace Date values with this date. Use the yyyy-MM-dd format. * number_value: Replace Number values with this number. * string_value: Replace String values with this text. * number_type: Accepts an integer number {#dps-create-anonymization-techniques__ul_cxg_ybw_4tb} |
   | Random Replace | This technique swaps values with randomly generated values. String and Number data can use this technique. |
   | Remove | This technique removes values, replacing them with empty (null) values. |
   | No Action | This technique is a placeholder. It does not modify fields when selected. |
   | Selective Replace with X | Transforms String data and selectively replaces sensitive characters with the letter X. Hinweis: Default technique for data patterns in [Exploring Data Discovery (Classic)](https://servicenow-prod.fluidtopics.net/thMiyiBrzEepPUQ7wvLswA "Use Data Discovery to identify sensitive data within an instance, such as credit card information, emails, or social security numbers."). |
   | Data pattern anonymization | Only anonymizes discovered data patterns within unstructured data fields while keeping underlying context intact. Hinweis: Settings for this technique reference data pattern anonymization technique settings in [Exploring Data Discovery (Classic)](https://servicenow-prod.fluidtopics.net/thMiyiBrzEepPUQ7wvLswA "Use Data Discovery to identify sensitive data within an instance, such as credit card information, emails, or social security numbers."). |

4. Select Add custom technique, if not using a pre-defined technique.
5. Fill in the fields in the Customize technique form.  
   {#dps-create-anonymization-techniques__entry__18}

   | Field1 | Description |
   |-|-|
   | Base technique | Select a pre-defined technique, as custom techniques are based on the pre-defined techniques. |
   | Technique name | Enter a name for the technique. |
   | Technique description | Enter a description for the technique. |
   [ ]

6. Select Next.
7. Enter the technique parameters.  
   The available parameterized values depend on which privacy technique you have selected. There are no parameterized values for the No Action and Remove techniques.{#dps-create-anonymization-techniques__table_a5r_bbm_lrb__entry__4}

   | Base Technique | Privacy Technique Parameter value | Description | Default value |
   |-|-|-|-|
   |   |   |   |   |
   | Selective Replace | end_index | Technique masks data from the start of the string to the specified character. If left empty, masking ends with the last character. | (Empty) |
   | Selective Replace | exclude_char | Character to skip masking. Only a single character can be used in this value. If more than one is entered, the first character is used. | (Empty) |
   | Selective Replace | replacement_char | Character to use when replacing values using a selective replace. | An asterisk (\*) is used if no other value is entered. |
   | Selective Replace | start_index | Technique masks data starting at the specified character. | If left blank, masking starts at the first character. |
   | Static Replace | date_time_value | Replace date and time values with this date. Use the yyyy-MM-dd HH:mm:ss format. | 1988-11-11 10:10:10 |
   | Static Replace | date_value | Replace date values with this date. Use the yyyy-MM-dd format. | 1988-11-11 |
   | Static Replace | number_value | Replace Number values with this number. | 1234567 |
   | Static Replace | string_value | Replace String values with this text. | TEXT123 |
   | Random Replace | preserve_data_length | Set to true to preserve data length. De-identified data will have the same length as the original data. | True |
