Fraudulent use of personal data has resulted in the introduction of laws and recommendations by most governments around the world (the General Data Protection Regulation (GDPR), Financial Services Modernization Act, and the HIPAA standard for the healthcare industry, to name a few). The need to comply with these laws, the risk of heavy fines and loss of business due to data leaks are all pushing companies to find solutions to protect the confidentiality of sensitive information. DOT-Anonymizer is an effective solution that maintains the confidentiality of test data by concealing personal information. It works by anonymizing the personal data while preserving its format and type.
