Data anonymization techniques adjust data across systems so it can’t be followed back to a particular individual while referential integrity and safeguarding the data’s format. It is one of a few methodology enterprises/organizations can use to agree with severe data security laws that require the assurance of personally identifiable information, for example, financial details, health records, or contact information.

1. What is Data Anonymization?

Data Anonymization is the way toward ensuring sensitive or private information by encrypting or erasing identifiers that interface a person to put away data. For instance, you can run Personally Identifiable Information, for example, addresses, social security numbers, and names through a data anonymization measure that holds the data yet keeps the source mysterious.

2. Data Anonymization Techniques

Data anonymization techniques are as under:

  1. Data masking: Data masking concealing data with changing values. You can make a mirror form of database and apply change strategies, for example, word or character substitution, encryption, and character shuffling.
  2. Pseudonymization: Pseudonymization de-identification and data management method that replaces private identifiers with pseudonyms or fake identifiers.
  3. Generalization: Generalization purposely eliminates a portion of the data to make it less recognizable. Data can be adjusted into a bunch of ranges or a wide area with suitable limits. You can eliminate the house number in a location. However, ensure you don’t eliminate the street name. The design is to wipe out a portion of the identifiers while holding a proportion of data precision.
  4. Data swapping: Data swapping is also called permutation and shuffling, a technique used to adjust the dataset attribute values, so they don’t compare with the original records. Swapping ascribes that contain identifiers esteems, for example, date of birth, for instance, may merely affect anonymization than membership type esteems.
  5. Data perturbation: Data perturbation changes the first dataset somewhat by applying techniques that round numbers and add arbitrary noise. The scope of values should be about the perturbation. A little base may prompt feeble anonymization, while an enormous base can diminish the dataset’s utility.
  6. Synthetic data: Synthetic data algorithmically made information that has no association with genuine events. Synthetic data is utilized to make artificial datasets instead of adjusting the first dataset or utilizing it with no guarantees and risking protection and security. The interaction includes making measurable models dependent on examples found in the first dataset.

3. Disadvantages of Data Anonymization

The GDPR specifies that sites should acquire consent from users to gather individual information, for example, cookies, device ID, and IP addresses. Gathering mysterious data and erasing identifiers from the database limit your capacity to get worth and knowledge from your data. For instance, anonymized data can’t be utilized for advertising endeavours or to customize the user experience.

4. Why is data anonymization important?

Data anonymization can help organizations keep PII private by veiling delicate attributes, even as they get business esteem from it for supplier outsourcing purposes, test data, analytic insights, customer support, and many more.

5. What are the key benefits of data anonymization?

Data anonymization is an approach to exhibit that your organization perceives and implements its obligation regarding confidential, personal, and protecting sensitive data in a climate of progressively complex data protection commands that may change depending on where you and your worldwide customers are found.

Customers who endow their delicate data to organizations will consider a break of that data, a penetrate of their trust also, and take their business somewhere else, therefore. Surely, one industry overview found that 85% of buyers won’t work with an organization on the off chance that they have worries about its security practices, and only 25% of respondents accept most organizations handle their PII mindfully.

Be that as it may, data anonymization isn’t just about dodging risk, it likewise improves the data quality and data governance. With trusted, clean data, you can enhance resources and applications, quicken cloud workloads, and ensure enormous data analytics and privacy, all of which drive advanced change by opening up safe data for use in making new business esteem.


The General Data Protection Regulation layouts a particular arrangement of decisions that ensure user data and make straightforwardness. While the GDPR is exacting, it licenses organizations to gather anonymized data without assent, use it for any reason, and store it for an inconclusive time insofar as organizations eliminate all identifiers from the data.
