Revises requirements for disclosure of a breach of security of certain computerized records containing personal information.

New Jersey's Assembly Bill A548 updates the state's data breach notification law by requiring businesses and public entities to notify New Jersey residents within five business days if their personal information (like names, account numbers, or passwords) is breached. This applies to any entity maintaining digital records containing such data, directly affecting residents whose information is compromised. The bill specifies notification methods (written, email, or website posts) and clarifies that delays are only allowed if law enforcement requests them to avoid hindering an investigation. It also mandates that entities document and retain proof if they determine misuse of the data is "not reasonably possible," requiring consultation with law enforcement before skipping notification.
