Implementing CCPA Consumer Rights

Implementing CCPA Consumer Rights

CCPA grants California consumers specific rights that require technical implementation. The right to know allows consumers to request disclosure of personal information collected, sources, purposes, and third parties with whom information is shared. The right to delete enables consumers to request deletion of their personal information, subject to certain exceptions. The right to opt-out requires businesses to provide mechanisms for consumers to direct businesses not to sell their personal information. The right to non-discrimination prohibits businesses from discriminating against consumers who exercise their privacy rights.
