Abstract
This Application sets forth techniques for establishing a custodial relationship between a user device and a custodian device for recovering access to a user account and/or to encrypted user data with assistance provided by the custodian device to effect access recovery. A server of a cloud network service provides an anonymous identifier to associate with the custodian device and an account recovery key to store at the custodian device. Identity of an account of the cloud network service associated with the custodian device can be hidden from the server. The user device generates a data recovery key and provides a first portion of the data recovery key to the custodian device and a second portion of the data recovery key to the server. Integrity of the stored account recovery key and portions of the data recovery key are checked regularly by the custodian device and the user device.
