Systems and methods for securely pairing a transmitting device with a receiving device

A non-transitory computer-readable storage medium encoded with instructions which, when executed by one or more processors, perform operations comprising:

• communicating with a first device via a first communication method over a wireless communication network;
• transmitting, to the first device via a second communication method, a first sensory pattern representing a first key, wherein:
• the first key is a security key;
• the second communication method is different from the first communication method;
• and
• the first key is encoded using a ciphering scheme;
• determining that a pairing configuration has changed;
• transmitting, to the first device via a third communication method, a second sensory pattern representing a second key, the third communication method being specified by the configuration,
• wherein the second key is encoded based on a ciphering scheme specified by the pairing configuration;
• and
• in response to determining that the first key matches a third key located on a server, the third key being a secret key:
• encrypting a message using a fourth key, the fourth key being a public key, and
• sending the encrypted message to the first device via the first communication method;
• communicating with the first device via a fourth communication method.
