Data Masking is the process of replacing authentic original data with data that is structurally similar but provides fake values. this means that the original format is retained but values are changed. The change in values takes place through methods such as encryption, shuffling, substitution, etc. The process of data masking makes it nearly impossible to obtain or reverse engineer original data, hence it is a one-way process.
Many tools are available on the market that makes the tasks of Data Masking easier, this article gives the Best Data masking Tools in the market.
What is Data Masking?
Data masking, as the name suggests, is a process to create a masked version of the true version of your organizational data retaining its original aspects. The main motto is to provide a functional solution that does not contain real and sensitive data but instead provides a copy of the structure. Data masking is mainly used for software testing, product demo, or user training, where real data is not required.
Data masking retains the original structure of data and changes its values. the data produced after data masking is nearly impossible to reverse engineer or decipher. This takes place by following methods like shuffling, substitution, and encryption.
What are the Benefits of Using Data Masking?
- Prevents Critical Threats: data loss, data exfiltration, insider threats or account compromise, and insecure interfaces with third-party systems.
- Cloud Adoption: Reduces data risks associated with cloud adoption.
- Encryption: this Makes data useless to an attacker while maintaining many of its inherent functional properties.
- Reduces Exposure: Allows sharing data with authorized users, such as testers and developers, without exposing production data.
- Data sanitization: sanitization replaces the old values with masked ones since normal deletion of files still leaves traces of information.

What are the Data Masking Techniques?
Many Data Masking Techniques are available, a few of them are mentioned below.
In the process of data encryption, the data is coded and it requires a decryption key to decipher it. unless there is a key the data is meaningless. the data masking is done by an encryption algorithm. It is one of the most secure means of data masking but it is very complex to implement because it requires advanced technology to encrypt, manage and generate keys for the data.
Characters of the value in data are reorganized in random order and then replaced with the original content. For example, an ID number such as 76498 in a production database, could be replaced by 84967 in a test database. This method is very simple to implement, but can only be applied to some types of data, and is less secure.
When an unauthorized user tries to access the data it shows “null” or missing. this makes data less useful to use for development and testing purposes
The real values of the data are replaced by values of any function like the lowest and highest values, mean values, or any other function. For example, if a customer purchased several products, the purchase price can be replaced with a range between the highest and lowest price paid. This can provide useful data for many purposes, without disclosing the original dataset.
Data values are substituted with values that belong to a realistic range similar to the real values, For example, real customer names are replaced by a random selection of names from a phonebook.
It is similar to substitution, but the data is shuffled from the data. this means that original data is present in masked data but it is shuffled. Data is rearranged in each column using a random sequence; for example, switching between real customer names across multiple customer records. The output set looks like real data, but it doesn’t show the real information for each individual or data record.
What are the Types of Data Masking?
Follow along to understand the various types of data masking.
1) Static Data Masking
Static data masking techniques assist you in creating a clean replica of the database. The method modifies all sensitive data at rest until a copy of the database can be safely shared. This process creates a backup copy of a production database, loads it to a separate environment, removes any extraneous data, and then masks data while it is static. The masked copy can then be delivered to the desired location.
It is utilized to deliver high-quality (realistic) data for application development. Static data masking can be performed using ETL-like solutions or technologies that can perform it directly within the database.
2) Deterministic Data Masking
Deterministic Masking is the process of mapping two values so that one value in a column is replaced with the same value whether in the same row, table, database/schema, or instance/server/database type.
This approach is useful in many situations, but it is generally less secure.
3) On-the-Fly Data Masking
On-the-Fly Data Masking occurs throughout the process of transporting data from one environment to another without the data touching the disk along the way. T When necessary, this method sends smaller subsets of masked data whenever required. Each subset of masked data subset is saved in the development/test environment for usage by the non-production system.
To avoid compliance and security difficulties, it is essential to apply on-the-fly masking to any feed from a production system to a development environment at the start of a development project.
4) Dynamic Data Masking
This masking procedure is identical to on-the-fly masking, with the exception that data is never stored in a secondary data store in the development/test environment. It is instead streamed directly from the production system and ingested by another system in the development/test environment.
This masking procedure aids in the prevention of unwanted access to sensitive data by allowing customers to select how much sensitive data to reveal while minimizing the impact on the application layer.
