Claim:
1. A method for wireless digital communication, the method comprising: receiving a wireless transmission at a receiver device via a light sensor of the receiver device, the receiver device communicatively coupled to a user device via a wireless Bluetooth connection, the wireless transmission sent from a wireless transmitter via a light-based wireless transmission protocol thereby making the wireless transmission interpretable by the receiver device but not by the user device; decoding a message code at the receiver device, the message code included within the wireless transmission; retrieving a receiver code from a memory of the receiver device; identifying that the message code matches the receiver code; identifying that the receiver device is authorized to read a message encoded within at least a subset of the wireless transmission based on the identified match between the message code and the receiver code; decoding a message included within the wireless transmission based on the identification that the receiver device is authorized to read the message; identifying that the message includes executable software as a first content type and at least one second content type selected from a text content type, an image content type, an audio content type, a video content type, a document content type, a data structure content type, and a data file content type; receiving a setting from the user device, the setting identifying that the first content type is disallowed in the message; modifying the message by removing the first content type from the message without removing the second content type from the message; and transmitting at least the modified message from the receiver device to the user device via the wireless Bluetooth connection, thereby outputting at least a subset of the message at the user device.
