The recommended approach for sanitizing data of personally identifiable information or payment card information before storing it in Cloud Bigtable is option C: De-identify the data with the Cloud Data Loss Prevention API. The Cloud Data Loss Prevention (DLP) API is a powerful tool that allows you to automatically discover, classify, and redact sensitive data in your organization. It uses advanced machine learning techniques to accurately identify and protect a wide range of sensitive data types, including personal information such as names, addresses, phone numbers, and payment card information. Using the DLP API to de-identify your data before storing it in Cloud Bigtable is the most effective way to ensure that sensitive information is protected and not accessible to unauthorized users.

Option A: Hashing data using SHA256 is not sufficient for protecting sensitive information, as hashes can be reversed using various techniques. Option B: Encrypting data using elliptic curve cryptography is a good option for protecting data, but it requires that you have a secure way to store and manage the encryption keys. If the keys are lost or compromised, the data will be inaccessible. Option D: Using regular expressions to find and redact phone numbers, email addresses, and credit card numbers can be effective in some cases, but it requires that you have a complete and up-to-date list of all the data patterns that you want to protect. It is also prone to errors and may not be able to detect all instances of sensitive data.

Without any doubt C is the right answer as the DLP API is a flexible and robust tool that helps identify sensitive data like credit card numbers, social security numbers, names and other forms of personally identifiable information (PII).

Cloud Data Loss Prevention API provides obfuscation and de-identification methods like masking and tokenization. Especially for credit card transactions, the card numbers are supposed to be tokenized. Therefore, this API is helpful.
