<ul data-eligibleForWebStory="true">WhatsApp has joined a legal challenge against the U.K. government's demand for access to encrypted customer data owned by Apple.The order was issued under the U.K.'s Investigatory Powers Act by the U.K. Home Office in January.Apple responded by withdrawing iCloud Advanced Data Protection from the U.K. and launched a legal challenge.Two human rights campaign groups, Privacy International and Liberty, also filed a legal action against the demand.WhatsApp stated that it would challenge any attempt to weaken encryption and support people's right to private online conversations.The U.K. Home Office has not specifically targeted WhatsApp with a similar order like the one given to Apple.A London court hearing related to Apple's appeal was held in secret, with media barred from attending.Security Minister Dan Jarvis has not confirmed the order's existence but mentioned the importance of balancing privacy and security.Authorities argue that strong encryption can hinder investigations into serious crimes such as terrorism and child exploitation.In April, the Investigatory Powers Tribunal revealed that Apple is contesting the order and denied a request to keep case details confidential.
