Suitable Design pattern [closed]

I am looking for the suitable design pattern for my use case. Let's I have list of account and I would like to enrich each of the account depends of the criteria. e.g.:

• if the account belongs to US account, account will be prepend with prefix US
• all the confidential field will be masked
• etc

I am thinking to use pipeline to solve this problem. Can someone give some advise?

Pipeline design pattern implementation

Thanks
