Data communication via data packet headers

A data processing method, comprising:

• at a receiver device having one or more processors and memory storing program modules to be executed by the one or more processors:
• obtaining a sequence of data packets from another electronic device that is communicatively coupled to the receiver device via a wireless network;
• decrypting the sequence of data packets, wherein each decrypted data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective decrypted data packet;
• retrieving data from the data length fields of the sequence of decrypted data packets according to a second data format distinct from the first data format;
• and
• performing operations in accordance with the retrieved data.

An electronic device, comprising:

• one or more processors;
• and
• memory having instructions stored thereon, which when executed by the one or more processors cause the processors to perform operations comprising:
• obtaining a sequence of data packets, wherein each data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective data packet;
• assigning data to the data length fields of the sequence of data packets according to a second data format;
• and
• encrypting the sequence of data packets that include the assigned data;
• and
• sending the sequence of encrypted data packets to a receiver device that is communicatively coupled to the electronic device via a wireless network, wherein the receiver device is configured to retrieve the assigned data from the data length fields of the sequence of data packets according to the first and second data formats and perform operations in accordance with the retrieved data.
