Anonymize identification number

[SorenB (Søren Schytz Birk)]

Hello

I am building a library that should be able to anonymize identification numer in this format:

• 112233-4455
• 1122334455

I would like to be able to anonymise either from the left or right, base on an in-argument for “number of characters to anonymize” is positive or negative Eg.:

• ‘6’ should replace the first 6 characters with XXXXXX
• ‘-4’ should replace the last 4 characters with XXXX

How is this done in the smartest way?

one of many options:

using regex
select the pattern depending to the input argument

• e.g. with the help of a switch activity

using Regex.Replace

e.g.:

And

[CheatSheet] - System.Text.RegularExpressions | RegEx

This CheatSheet introduces the basic use of regex functions. With further examples also special cases are presented. Introduction From the namespace System.Text.RegularExpressions following methods are offered: Regex.Match Regex.Matches Regex.isMatch Regex.Replace Regex.Split A simple usage for example would look like this: [grafik] Recommendation: add System.Text.RegularExpressions to the imports: [grafik] it allows to use the shortened statement, as the namespace part can be ommited…

@SorenB,

Try these steps:

1. Assign lengthToAnonymize = Math.Abs(numCharactersToAnonymize)

2. If numCharactersToAnonymize >= 0
   Then:

   • Assign prefix = New String("X"c, lengthToAnonymize)
   • Assign suffix = inputNumber.Substring(lengthToAnonymize)
   • Assign anonymizedNumber = prefix + suffix
     Else:
   • Assign prefix = inputNumber.Substring(0, inputNumber.Length - lengthToAnonymize)
   • Assign suffix = New String("X"c, lengthToAnonymize)
   • Assign anonymizedNumber = prefix + suffix

3. Return anonymizedNumber

Thanks,
Ashok
