(ASCUIRS) Mr.Lokesh S. Khedekar 1 , Dr.A.S.Alvi 2 PRMIT&R,Badnera,Amravati,India,lokeshkhedekar@gmail.com 1 PRMIT&R,Badnera,Amravati,India,abrar_alvi@rediffmail.com 2 ABSTRACT Today barcode system is very popular to identifying a unique product. Many organizations are using this technique for identifying a unique product. Tracking these items has historically been done by the use of bar-code technologies, which suffer from lack of efficiency, robustness, difficulty in automation, inability to have secure or dynamic data, etc., whereas the 2D Data matrix has the ability to overcome several of these limitations over barcode This paper presents a comparative basis for the Advanced Smart Credential cum Unique Identification and Recognition System via 2D Data matrix versus other technologies such as barcode and QR code. Keywords: Barcode, Data Matrix, Encoding, QR Code, SCUIRS. I. INTRODUCTION This proposed paper is related with the implementation of a product that will combine the power of graphical representation and the power of random numbers and characters for a unique ID. Combination of both Unique ID and Unique image will help a user to identify the product from other products and store its information accordingly. ASCUIRS will not only give you a complete solution to product identification but can facilitate you with one more option. ASCUIRS will also act like a Security system. The basic idea behind the designing of ASCUIRS is to use the feature of Unique numbers combined with unique images and form a unique combination that will help in recognizing the product or a user or any item in inventory. 1.1 Existing Systems 1.1.1 Barcode System 97

International Journal of Computer Engineering and Technology (IJCET), ISSN 0976-6367(Print), ISSN 0976 – 6375(Online) Volume 4, Issue 1, January- February (2013), © IAEME There are a variety of methods you can use to print BarCode [1]. We recommend thelowest cost alternative to get started – a barcode font. Barcode fonts give you an inexpensiveand flexible way to print labels quickly with high resolution and a low initial investment. Thelocation barcode is important because the goal of the inventory system is to know not onlywhat you have, but to be able to tell accurately where it all is. You can get creative with thelocation barcode. The first barcode was developed by Bernard Silver and Norman Joseph Woodland inthe late 1940’s and early 1950’s. The first commercial use of barcodes was by theRCA/Kroger system installed in Cincinnati on the call of the National Association of FoodChains (NAFC). However it was not widely used until the Universal Product Code (UPC) [2]was introduced into America and adopted by the U.S. Supermarket Ad Hoc Committee.Today’s barcodes have two forms: one dimensional (1D) barcode and two dimensional (2D)barcode [3][4]. The 1D barcodes use bars and gaps to encode identification information suchas serial numbers. The 2D barcodes [5] consist of more complicated patterns and may encodeup to 4K bytes of data. Figure 1 shows the 1D barcodes. Although 1D is the more prevalentbarcode used in daily life. Figure 1. 1D Barcode and 2D BarcodeFigure 2 illustrates a basic barcode system. Barcodes are read or scanned by a barcode readerand the reader is connected to a computer. The operator has to physically align/point thebarcode reader with/to the barcode to read the identification information. The softwarerunning on the computer processes the identification information picked up by the scanner.Programmable Logic Controller (PLC) is usually used to control the scanner in moreautomated process such as production line. The primary scanning technology for barcode isLED (Light-Emitting Diode). More advanced scanning such as CCD (Charge-CoupledDevice), Laser, and Imager are used in industry automatic processing.

International Journal of Computer Engineering and Technology (IJCET), ISSN 0976-6367(Print), ISSN 0976 – 6375(Online) Volume 4, Issue 1, January- February (2013), © IAEMEBarcodes can be printed from most printers. 1D barcodes usually have coded readable IDprinted along with the barcode. Barcodes can be read by barcode scanners which we see at atypical Point of Sale (POS) in retail stores. The barcode can be printed from any black/whiteprinter. Since the barcode can be directly printed on an object or on paper label, the cost for abarcode is typically less than 1 cent [6].Disadvantage of Barcode System:Barcodes are graphic images featuring a series of lines or bars, of varying thickness,positioned parallel to each other in such a way that a scanner passed along the image willtranslate their thickness and spacing with relation to each other as a series of numbers orcode.This code is then interpreted by customized software to produce pricing and stockinginformation in an effort to assist in the automation of the retail sales and stocking processes.It is a very efficient and effective system, but, like any other method of tracking inventory, itis not foolproof.Pricing Discrepancies and Scanning ProblemsWhen discounts apply to bar-coded merchandise, store employees may forget to code in thediscount price. This, in turn, can lead to confusion and delays at the checkout counter,inconveniencing the customer, the checkout clerk, and other customers waiting in line. If abarcode cant be scanned, for any reason, the clerk must then read the corresponding numericcode and enter it manually. Because clerks have become used to scanning barcodes quicklyand automatically, without any additional effort on their part, their lack of practice in manualcode entries may potentially cause them to be slow and/or inaccurate in entering theinformation, further delaying the checkout process.Label DamageBarcodes that are printed on a torn section of packaging, or that have been smeared, smudgedor otherwise damaged, will present additional scanning problems. If the correspondingnumeric code is also illegible due to damage, the checkout process can be significantlydelayed while another package of the same merchandise is located and brought to thecheckout counter for scanning.Financial and Equipment CostsFor businesses that are not already equipped for barcode checkout, the cost of the equipmentnecessary to implement the new system can be prohibitive. Other delays can occur in trainingemployees to adapt to new equipment, and expensive printers must be purchased to printcoded labels for any merchandise that doesnt come prepackaged with a barcode already on it.Dot matrix and ink jet printers, for example, are generally incapable of printing finely-detailed barcodes.1.1.2 QR Code QR Code (abbreviated from Quick Response Code) is the trademark for a typeof matrix barcode (or two-dimensional code) first designed for the automotive industry. TheQR barcode [7] is a two dimensional symbol developed by Denso Wave in 1994. Morerecently, the system has become popular outside the industry due to its fast readability andlarge storage capacity compared to standard UPC barcodes. The code consists of blackmodules (square dots) arranged in a square pattern on a white background. The informationencoded can be made up of four standardized kinds ("modes") of data (numeric,alphanumeric, byte/binary, Kanji), or through supported extensions, virtually any kind ofdata. 99

International Journal of Computer Engineering and Technology (IJCET), ISSN 0976-6367(Print), ISSN 0976 – 6375(Online) Volume 4, Issue 1, January- February (2013), © IAEMEThe code contains information in both the x-axis and y-axis, whereas traditional barcodescontain data in one direction only. The outer range is the quiet zone. The upper-left, upper-right, and left bottom square areas of QR code [8] are used for position detection and patternseparators for positioning.Figure 3 depicts basic block diagram of QR Code scanning with any image capturing device. Figure 3 QR CodeAdvantage of QR codes There is no need to write vital details down. A simple scan captures the desiredinformation. QR Codes can be used to store addresses and URLs that can appear in magazines, on signs,buses, business cards or just about any product that users might need information about.Disadvantages of QR codes Users must be equipped with a camera phone and the correct reader software that can scanthe image of the QR Code. Currently only Smartphone’s are technically equipped to do this.Many users that have mobile phones that have cameras are unable to get QR reading softwarefor their phones.II. GENERAL STRUCTURE 2-D bar code consists of a certain white and black geometric modules thatalternately arrange in the vertical and horizontal directions according to certain rules seeFigure, and it is a symbol with large capacity for storing information. As the 2-D bar codewith smallest size in the world, data matrix code is widely applied to electronic productcomponents. 2-Dbar code recognition technology shows great commercial value, and atpresent, most COTS (commercial of the shell) recognition algorithms are proprietary andprotected by patents, so the 2-D bar code recognition technology is in a great demand forresearching.

PROBLEM DEFINITION When user will store the product information the unique ID will be generated. ThisUnique ID will be Tier 1 identification for the product information. Entering this Unique ID as anInput to our Selective algorithm will generate a unique Image for that particular ID. This Uniqueimage will act as Tier 2 identification for product information. This image will be hash mapped to theUser Unique ID and both will be used to identify product information. When identifiers are usedsolely within a database, their generation should be left to the database itself.3.1 ASCUIRS Working To generate a unique image from a unique ID and to map the image to a specific item in an inventory. When user will store information about a product or person a unique ID will be generated. This Unique ID will be Tier 1 identification for the User or Object. Entering this Unique ID as an Input to our Selective algorithm will generate a unique Image for that particular ID. This Unique image will act as Tier 2 identification for User or Object. This image will be hash mapped to the User Unique ID and both will be used to identify an object. 3.2 Proposed Dataflow Diagram Figure 5.Dataflow Diagram 101

International Journal of Computer Engineering and Technology (IJCET), ISSN 0976-6367(Print), ISSN 0976 – 6375(Online) Volume 4, Issue 1, January- February (2013), © IAEME • GUI: Graphical User Interface will be used to gather information regarding the inventory from the user. GUI will consist of components to take inventory information and details from the user, components to save, edit, retrieve (searching) and delete the information. GUI will also contain a separate module for Unique ID (generated by the database and encrypted by selective algorithm) passing to generate an unique data matrix image. • Selective algorithm for Unique ID encryption: This algorithm will be a modified version of 56 bit key DES algorithm. The selective algorithm will be used to encrypt the unique ID before been passed on for conversion into data matrix image. • Selective algorithm for unique image The algorithm will encode the pre encrypted Unique ID and a data matrix will be generated that will be used for printing or publishing as required by the user. • Storage of Unique ID: Database will store inventory information and details and a Unique ID will be generated and associated with every record. This Unique ID will act as Tier 1 identification for the record. • Web server process and retrieval: A portal will be established which will contain the GUI and the entire process of storage of Data and retrieval along with data matrix image generation and publishing process.IV. PROPOSED SYSTEM • Web Portal:Web portal will contain a module that will take an input from the client which will be a data matrix image. • Data inventory: Tables, relations related to items will be stored in data inventory. Data inventory is nothing but a set of tables that will contain records about items and its detailed information. • Database: Information entered by the administrator will be stored in the database. This information will be stored in the form of a tuple. Each tuple will have a unique ID associated with it. • Unique ID: This will be a 16 bit ID generated by the database (MySQL) and it will be used to identify the tuple in case of searching. • Unique ID passed to (selective) algorithm: The algorithm will encrypt the Unique ID generated by database (MySQL). This encrypted key or string will be further passed on to another selective algorithm to create a unique image (i.e. Data Matrix image). 102

International Journal of Computer Engineering and Technology (IJCET), ISSN 0976-6367(Print), ISSN 0976 – 6375(Online) Volume 4, Issue 1, January- February (2013), © IAEME • Uploading of Image: An FTP request to the server will carry the clipped image that will be used to map with the database to find the related record or information. • Sending information back to client: If mapping returns a record, then it will be sent back to the client (i.e. browser of phone or computer system) and this will complete the process.V. CONCLUSION Using this image through scanner or mobile phone camera we can decompileproduct’s information. The product’s information can be accessed anywhere if the database isstored and accessed through a web server. This ensures portability and security since theunique number will only be known to the organization. Organization will be using a uniqueimage to access their product information or person or object. A new algorithm is proposedhere which is a hybrid model for data hiding in data matrix and provides decoding algorithmwhich is independent of image orientation in any direction and de noising is one of the mainadvantages of this. It runs at 640×480 resolution for real time scenarios. For practicalimplementation dimensions of data matrix image is 420×420 includes finder pattern of 10×10ad size of squares is 20×20.This proposed system provides an accuracy of 97.6%.REFERENCES[1] On The Creation of Automatic Identification and Data Capture Infrastructure via RFIDXiaoyong Su, Chi-Cheng Chu, B.S.
