Latest Patents
Daniel holds 1 patent for his invention titled "Methods and systems for end-to-end encrypted message history exchange." This patent describes exemplary embodiments that relate to methods and systems for transferring a user's messaging history from one device to another. The primary device, which stores the official truth of the user's messaging history, establishes an end-to-end encrypted session with a new device using a first decryption key during the initial session setup. The primary device may conglomerate all or a portion of the messages comprising the user's messaging history into a data blob, which is encrypted and sent to a blob store. An end-to-end encrypted message is sent from the primary device to the new device via an intermediate server. This message includes a second key for decrypting the data blob and a pointer to the location of the data blob on the blob store. The new device retrieves the data blob from the blob store and decrypts it using the second key to extract plaintext versions of the user's messages, adding them to the messaging application on the new device. Multiple data blobs may be sent until all or a desired subset of the user's messaging history is present on the new device.
