As part of WhatsApp’s new feature to privately add and manage your contacts on WhatsApp across linked devices, we’re announcing a novel encrypted storage system we’ve designed called Identity Proof Linked Storage (IPLS). IPLS is a novel system at WhatsApp that allows users to store their contact names in an encrypted way.

A growing percentage of Internet traffic is protected by encryption. According to Google , approximately 95% of web browsing uses the encrypted HTTPS protocol. This trend toward traffic encryption has been driven by a few different factors. The move toward data encryption is a mixed blessing for cybersecurity.
