Abstract

Quick Response (QR) codes are now extremely popular due to the widespread uses of smart phones. Almost all the areas have had the QR codes to overtake the traditional one-dimensional bar codes, due to the increased capacity and quick data retrieval. QR codes offer a myriad of specifications like small space,durability against damage due to soil, better data capacity and higher language support, which make them much better than bar codes. Further, this Project is attempting expand the size of the QR codes further by making use of Color QR codes. Blowfish algorithm is efficient. This has been proved due by measuring the time required for its execution as well as its throughput. Due to the use of large key size, the efficiency of the algorithm may be affected. Further, the data which is considered is encrypted using Blowfish Algorithm, which makes the data secure and tamper-proof. Blowfish Algorithm belongs to the class of the algorithms which have a symmetric block cipher. The block cipher has a size of 64 bits and the key is variable, having a key length which can range from 32 bits until 448 bits at the maximum. This algorithm is a  very fast and a useful scheme. It consists of a sub-key, an S-box phase and the actual encryption phase.
