Patent number: 11727130Abstract: Exemplary embodiments are directed to a method for allowing a user at a first client device to provide access to restricted content on a content provider server to a user at a second client device without providing identifying information of the second client device or the user to the content provider. The content provider receives a request from a messaging app on a first client device for sharing of a content item with a second client device and generates a metadata block comprising at least a link to the content item. The metadata block is sent to the first client device and, in response, a public key of a private/public key pair of the second client device is received from the first client device. A request for the content item, is then received and contains a data item digitally signed using the private key of the private/public key pair of the second client device. The public key is then used to verify the digitally signed data item, thereby confirming the identity of the second client device.Type: GrantFiled: April 18, 2022Date of Patent: August 15, 2023Assignee: WhatsApp LLCInventor: Cheng Tian
