Dynamo Color Coding System (DCCS) is a dynamic real time database and color-coding system that has uniquely been combined into a single web based application. The purpose of the DCCS is to give Producers an efficient mechanism to track, validate and authenticate their goods and services as they travel through the supply chain. The attributes for the data to be coded are defined real time and are virtually unlimited. Once the attributes are defined the data is entered using alphanumeric, characters or images into the system and processed through the encoder. The encoder is uses MDCT and Vector Quantization technology, along with the Mobis function. While the data is being processed through the encoder a time stamp and reference number is embedded into the code for authentication. Once encoded a label is created with the color code, the vector of the code and the color space vector. The application can create the code in many shapes that include honeycomb, squares, circles, PDF417 Barcode. The decoding process requires a secure log in and has 3 levels of validation 1) color plus interleave, 2) space decoding and 3) background and foreground color match. The device used for decoding includes RF Reader, digital camera, scanner or any other digital reading device. In addition, the code can be encapsulated into RFID chips, I Buttons or any other device. The verification is done through reading the code with a device and logging into the secure web site. The system conducts a match between the image that was read and the image stored in the database. The data and code are stored in a centralized repository. Dynamo Color Coding System is easy to incorporate into the existing manufacturing and supply chain pipeline and is easy to decode using any digital input device capable of capturing a digital image of the DCCS pattern.
