Abstract
Exemplary embodiments relate to techniques for anonymizing information in an end-to-end (E2E) encrypted environment; the information may include, for example, statistical data about unique page/message views, view counts, view time, what users selected on the message or page, etc. Exemplary embodiments may prevent an E2E system server from being able to identify which user is associated with which record. Various examples are described, including an embodiment in which an originating client generates the data, encrypts it, and sends it to a random contact. The contact decrypts the data, re-encyrpts it, and sends it to another random contact. The procedure continues for a set amount of time or for a set number of hops. Other embodiments relate to wrapping the data in various layers of encryption and sending the data to clients in a chain. The encrypted layers prevent clients along the chain from being able to view the anonymized data.
