According to GDPR Article 32:

The controller and the processor shall implement appropriate technical and organizational measures to ensure a level of security appropriate to the risk including the pseudonymization and encryption of personal data.

GDPR defines pseudonymization as:

‘pseudonymization’ means the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately and is subject to technical and organizational measures to ensure that the personal data are not attributed to an identified or identifiable natural person.

Databunker complies with the definition of pseudonymization. User personal data is encrypted and stored separately from the application database.

When saving a user object in Databunker you are getting a user token. This user token is a user pseudonymised identity.

So, now when performing a cross-border transfer or saving application logs, change user identity (email, name, etc…) with a Databunker user token.

This way you make the user not identifiable directly. This method is compatible with Schrems II.

According to “The GDPR made simple(r) for SMEs” book, published in 2021:

To comply with Data Protection by Design (DPbD) and Data Protection by Default (DPbDf), a company may consider implementing Privacy Enhancing Technologies (PETs).

PETs encompass a wide range of solutions, incorporating both traditional data security technologies (e.g. anonymization, encryption cryptography, for personal data both being stored or moved) and other tools aimed at a more general strengthening of data protection: for example, antitracking tools for web browsing, dashboards and other user interfaces for the management of consent can be considered, as well as tools that enable data subjects to audit the enforcement of the data protection policy of a controller or to customize the terms and conditions of privacy policies.

Databunker stands most requirements for Privacy Enhancing Technology. Databunker can serve as a cornerstone for your privacy by design compliance.

Databunker is a special encrypted database for sensitive personal records and Personally Identifiable Information (PII).

Since the GDPR has not made data encryption a mandatory method for imposing data security, not implementing data encryption is not a violation of GDPR compliance.

However, data breaches are a common occurrence, specifically with such a thriving cybercriminal landscape.

Amidst this, any organization falling victim to a data breach might be able to avoid GDPR fines if it implements data protection through encryption.

Upon an API request to create a new user record, Databunker performs the following operations:

• Request sanity check and access validation check.
• Normalize email address, phone number, login name.
• Strict user schema validation if the schema is defined in the configuration. Generate an error if some fields are missing or error.
• Securely encode email address, phone number, login name.
• Check for duplicate email, phone, and login records. Generate an error in case of duplicates found.
• Random generation of a user UUID token to be used as the main user index.
• Encrypt the whole user JSON and save it in the backend database (MySQL, PostgreSQL, SQLite).
• Return user token (UUID generated before) to the API caller.

Now, when Databunker returns a user token, you can store it in your existing database instead of storing personal records in clear text (PII).

This customer token is basically a user pseudonymised identity.

Afterward, you can query the Databunker service using the user token to receive user personal data, saving the audit trail. You can also perform user record lookup using the email address, login name, or phone number.

Upon user record creation request, Databunker knows to extract user email, phone, login name, and build an encrypted search index.

Databunker product gives your customers passwordless access to the Databunker user privacy portal. Upon login attempt, the product sends your customer a one-time access code. This code is sent by SMS or email.

Databunker gives the user temporary access to view his data, initiate personal information change (data rectification request), start the forget-me operation, manage privacy agreements, or view audit events.

Upon any user action (depending on configuration), Databunker sends a notification email to Data Privacy Officer (DPO).

DPO can use Databunker to approve or reject user requests. For example, DPO can approve user forget-me requests.

Using the Databunker management portal, DPO or Data Privacy Officer can view all user requests, configure processing operations, and view audit events.

When creating web applications sometimes you need to save data in a session object. This data can include user email address, user permissions, last operation code, error messages. A session can be defined as server-side storage of information that is desired to persist throughout the user’s interaction with the website or web application.

Some of the information stored in the session is considered personal data or Personally Identifiable Information.

GDPR stands on a number of principles. Integrity and confidentiality are some of them. These principles tell that appropriate security measures should be in place to protect personal data.

Databunker has an API for secure storage on session objects inside Databunker’s encrypted store. Node.js modules and examples provided:

A Consent management platform (CMP) empowers users to manage and document the consent of the users.

Databunker has a buil-in consent management platform. Databunker provides you with the following tools:

1. User consent managenent
2. DPO processing operations management
3. API to fetch and update user consent choice. You can easily integrate it with your backend system.
