Personally Identifiable Information (PII) circulates more easily than ever before, making privacy and data protection a top priority for businesses and organizations.

PII masking has become an essential technique to protect personal data from unauthorized access.

This article provides insights into what PII masking is, techniques to ensure it, and how icaria TDM guarantees the security of personal data.

What is PII Masking?

PII Masking refers to the process of concealing personal data to prevent direct or indirect identification of individuals. PII includes any information that can be used to identify a person, such as names, addresses, phone numbers, and more. By masking this data, organizations protect individuals' privacy while using or sharing information for analysis, testing, or software development without compromising functionality.

Techniques to Ensure Effective PII Masking

Various techniques can be employed to ensure PII masking, each suited for different contexts and security needs. Here are some key techniques:

Substitution

Substitution replaces sensitive data with fictitious or random characters. For example, a name like "John Doe" could be replaced with "Name123" or a generic placeholder. This technique is ideal for testing environments where real data is not required to validate processes.

Obfuscation

Obfuscation alters personal data while retaining its format, making it useful for analysis or testing without revealing the actual information. This could involve systematically changing numbers or dates, ensuring the data remains functional without exposing real values.

Hashing with Salt

Hashing with salt is a cryptographic method that converts PII into a unique string of characters using hashing algorithms, with an additional random value ("salt") added to each entry. Even if two individuals have the same PII, their hashed results will differ, providing enhanced security.

Tokenization

Tokenization replaces sensitive data with non-identifiable tokens, which can be used without exposing the original information. Unlike hashing, tokenization allows data to be securely reversed under controlled conditions, making it essential for processes requiring retrieval of original data.

Data Reduction

Data reduction involves removing unnecessary details while maintaining relevant information for specific analyses or tests. For instance, in a medical study, names and addresses may be removed, leaving only relevant data like age or postal codes to protect privacy.

Each technique offers unique benefits for safeguarding PII, depending on the level of security required and the specific data usage context.
