Let's examine some example messages that a user might send:

// User is sending an IBAN
John Doe, TR320010009999901234567890 is my IBAN.

// After masking:
John Doe, ** is my IBAN.

// User is sending a T.C. number
My ID number is 10928416630.

// After masking:
My ID number is **.

// User is sending both a Turkish ID number and a phone number
My ID is 10928416630, and my phone is +905455455454.

// After masking:
My ID is **, and my phone is **.
**Please note that the examples given above are all used as an example, they typed randomly

We can mask such personal information by adding regex patterns.

Here's how you can do it to add masking to a channel:

1. Locate the channel where you want to add masking in the Channels section.
2. Click the lock icon next to the channel in the list.
3. In the popup window, you will see IBAN and EMAIL regex values. Activate the ones you want by using the buttons in the Status field.
4. Click the Save button.

If you want to add a new regex pattern, other than IBAN and email:

1. Click the "+" button.
2. In the "Name" field, provide a description for your regex pattern, indicating what it filters (e.g., "Turkish phone").
3. In the "Regex" field, enter the regex pattern you want (e.g., "(?:\+90.?5|0090.?5|905|0?5)(?:[01345][0-9])\s?(?:[0-9]{3})\s?(?:[0-9]{2})\s?(?:[0-9]{2})").
4. Click the Save button, and the window will close, displaying your entry in the list.
5. Activate it by using the Status field.
6. Click the Save button.

In the example above, we provided a regex pattern for masking Turkish phone numbers. Be aware that users may send variations of messages, and you may need to add additional regex patterns or improve your existing ones to handle such cases.

Here are a few example regex patterns:

// Credit card
([0-9]{4})\\\\s?([0-9]{4})\\\\s?([0-9]{4})\\\\s?([0-9]{4})

// Turkish ID number
[1-9]{1}[0-9]{9}[02468]{1}

// Visa credit card
4[0-9]{12}(?:[0-9]{3})?

// American Express
3[47][0-9]{13}

//TR IBAN
\bTR\d{2}\s\d{4}\s\d{4}\s\d{4}\s\d{4}\s\d{4}\s\d{2}\b

//Saudi Arabian
\bSA\d{2}\s*\d{4}\s*\d{4}\s*\d{4}\s*\d{4}\s*\d{0,18}\b

//German
\bDE\d{2}\s*\d{4}\s*\d{4}\s*\d{4}\s*\d{4}\s*\d{4}\s*\d{0,2}\b
