Securing Sensitive Legal Data with End-to-End Database Encryption

Overview

In the legal profession, confidentiality is essential. Our client, a legal services provider, required to protect sensitive client data, such as personal information and case details, from potential data breaches or unauthorised access. We created a strong encryption solution to protect sensitive data and ensure it meets industry standards.

Solution

After examining several encryption algorithms, we created an advanced database encryption solution based on OpenSSL. Sensitive fields such as first and last name, email, phone number, case type, and case history were encrypted before storage. The encryption keys were securely stored outside of the application's coding, limiting unauthorised access even in the event of a code leak or server compromise. We provided an extra degree of security to these keys by encoding them in base64. For decryption, we used the same encryption library, allowing secure access to encrypted fields only when absolutely essential, such as for displaying information in the user interface or verifying data.

Results

Our encryption technology has successfully secured all sensitive data within the application, leaving it indecipherable to anyone without the necessary authorisation. This end-to-end encryption method reduced possible threats and gave our client assurance that sensitive data was completely secure, even in the worst-case situation.

Impact

The client's data security has been quantified as a result of our encryption strategy:
