EP3732813A1 — Methods providing transmission and/or searching of encrypted data and related devices

USPTO Abstract

Methods may be provided to transmit encrypted data from a communication device (200) to a remote storage system (100). A data value and information related to the data value may be provided, where the information related to the data value includes an identifier associated with the communication device and a time-value associated with the data value. A combination of the time-value and the identifier may be encrypted using a public key to provide a first encrypted value. The data value may be encrypted using the public key to provide a second encrypted value, and a hidden datum package may be generated including the time-value, the first encrypted value, and the second encrypted value. The hidden datum package including the time- value, the first encrypted value, and the second encrypted value may be transmitted to the remote storage system (100).
