Advanced Cycloshift Encryption (ACE) for Point of Sale Barcode System

As the world of trade increasingly continue to expand, more and more information technology systems are adopted to bring about flexible and easy transactions. In recent times cases of theft ranging from shop lifting to credit card data heist have been identified leading to huge financial losses worldwide. Due to the need for reduced administrative and running costs, shopping malls around the world are gradually adopting self-service systems. This comes well but not without a price – Security compromise! This research work probes into the scenario whereby a dubious customer manipulates the price tags of items for the sole purpose of disguisedly compelling the cashier to undercharge him (the customer). The researcher solves this problem by developing a novel robust encryption for price tags’ barcodes and designing a database structure which keeps track of items that have been tagged recently. of 6:1, 8:1 & 10:1, w/c ratio of 0.35, 0.4 & 0.45 have been used. Properties of no-fines concrete such as compressive strength, flexural strength and split tensile strength were performed. spacerun:yes'>  The organic part of the solid waste could be effectively utilized for vermicomposting process; thereby the solid waste pollution can be minimized. The Vermi treatment of the composted materials may be converted into vermi-compost. Fungal treatment of biodegradable waste helps to convert the material into compost quickly.  These processes can provide employment opportunities in urban and rural areas. Vermicomposting technology can be used as a source of income generation for the rural people in the recycling and utilization of biodegradable wastes.
