System Transformers

Introduction

Neosync comes out of the box with 40+ system transformers in order to give you an easy way to get started with anonymizing or generating data. There are two kinds of system transformers:

1. Generators - these begin with generate_ and do not anonymize existing data. They only generate net-new synthetic data.
2. Transformers - these begin with transform_ and can anonymize existing data or generate new-new synthetic data based on how you configure it.

Generate Categorical

The generate categorical transformer allows a user to define a list of comma-separated categorical string values that Neosync will randomly sample.

For example, the following values: test, me, please

Could produce the following output value: me

Or: please

Configurations

Name	Description	Default	Example Output
Categories	list of comma-separated categorical string values that Neosync will randomly sample.	value1,value2	value1

Examples

Categories	Example Input	Example Output
false	red,blue,green	green
false	red,blue,green	red

Generate Email

The generate email transformer generates a new randomized email address in the format:

<username>@<domain>.<top-level-domain>

By default, the transformer randomizes the username, domain and top-level domain while always preserving the email format by retaining the @ and . characters.

For example, the following input value: john@acme.com

Would produce the following output value: ytvub873@gmail.com

Configurations

There are no configurations for this transformer.

Examples

Example Output
f98723uh@gmail.com
9cd@msn.com
mDy@gmail.edu
fweq23f@hotmail.com

Transform Email

The transform email transformer can anonymize an existing email address or generate a new randomized email address in the format:

<username>@<domain>.<top-level-domain>

By default, the transformer randomizes the username, domain and top-level domain while always preserving the email format by retaining the @ and . characters.

For example, the following input value: john@acme.com

Would produce the following output value: ytvub873@gmail.com

Configurations

Depending on your logic, you may want to configure the output email. The transform email transformer has the following configurations:

Name	Description	Default	Example Input	Example Output
PreserveDomain	Carries over the input domain and top-level to the output email address.	false	john@gmail.com	fjf2903@gmail.com
PreserveLength	Ensures the output email address is the same length as the input email address.	false	john@gmail.com	hw98@gmail.edu
Excluded Domains	Specify a list of comma separated domains to exclude from transformation logic.	empty	gmail.com,hotmail.com	hw98@gmail.edu
Email Type	Specify how the email should be transformed. Today the options are uuid v4 and fullname. Fullname is not guaranteed to be unique, although it has high cardinality. For unique transformers, it's advised to use uuid v4.	uuid v4	foo@gmail.com	d62bcb6a98ee4316a078852efda21c3d@gmail.com

Examples

There are several ways you can mix-and-match configurations to get different potential email formats. Note that the Excluded Domains List pertains to the transformed emails. If the PreserverDomain is true and there is a domain in the Excluded Domains list, then the default logic would be to not preserve the domain but since we are excluding those domains from the transformation logic via the exclude list, then those domains will be excluded.

Here are some possible combinations:

PreserveLength	PreserveDomain	Exclude Domains	Example Input	Example Output
false	true	gmail.com	evis@gmail.com	f9nkeuh@ergwer.wewe
true	false	gmail.com	f98723uh@gmail.com	f98723uh@gmail.com

Depending on your validations, you may want to configure the output string. The random string transformer has the following configurations:

Name	Description	Default	Example Input	Example Output
Preserve Length	Preserves the length of the input integer to the output string.	false	hello	9Fau3

Examples

There are several ways you can mix-and-match configurations to get different potential random integer formats. Here are some possible combinations:

PreserveLength	Example Input	Example Output
false	bill	je7R6
true	lorem	i1NMe

Transform Character Scramble

Transforms a string value with characters into an anonymized version of that string value while preserving spaces and capitalization. Letters will be replaced with letters, numbers with numbers and non-number or letter ASCII characters such as !&* with other characters.

For example:

Original: Hello World 123!$% Substituted: Ifmmp Xpsme 234@%^

Note that this does not work for hex values: 0x00 -> 0x1F such as chinese characters.

Configurations

Name	Description	Default	Example Input	Example Output
Regex	A regular expression to match a part of the string to scramble. If no regex is specified that we will scramble the entire string.	empty	ello	hello -> hmato

Examples

There are several ways you can mix-and-match configurations to get different potential random integer formats. Here are some possible combinations:

Regex	Example Input	Example Output
	helloworld	didlenfioq
ello	Hello World!	Hjiqs World!
Hello 12	Hello 1234	Praji 2834

Passthrough

The passthrough transformer simplify passes the input data out to the output without making any modifications to it. This is useful in many circumstances but cautious of accidentally leaking sensitive data through this transformer.

Null

The null transformer simply returns a null value. This may be useful if you a column that can't be null but don't have a specific value that you want to insert.

Configurations

There are no configurations for the null transformer.

Examples

Here are some examples of what an output null value may look like.

Example Input	Example Output
N/A	null

Works-in-progress

This section is for detailing what we have limited or in-progress support for in regards to data transformations.

Array data types

Neosync has limited support for array data types today.

1. Passthrough - Array data types can be set to passthrough and have their values directly passed through from the source to the destination.
2. Null - If the column is nullable, this transformer can be safely set.
3. Default - If the column has a default set, this transformer can be set to allow the column be set to its default state.
4. Javascript Code - The JS code transformer has support for array data types as the logic is effectively up to the function's implementation.
