摘要：This research aim is to increase the capacity of barcode (i.e.) Number of data bits embedded inside barcode will be increased by encoding data through orientation modulation in elliptical dot array. BARCODES that encode digital data on physical media are commonly utilized in commercial applications for tracing/tracking of trade items, in security applications for linking personal documents with a user, or in other applications as an auxiliary channel to encode additional information on a physical medium. which are fundamentally analog, these methods can add security and functionality and features that are associated with digital techniques at the expense of consuming space on the media. For instance, in personal IDs, driving licenses and passports, high capacity can enable the encoding of a sample speech signal, a picture, or other identifying personal information which in turn may be used to establish authenticity of the user. Care must, however, be exercised in designing color barcodes to ensure that they are robust to variations in the color printing and scanning processes, which have a greater impact when considering color rather than black/white reproduction and capture.2D bar codes are being considered for new emerging applications such as M-ticketing, where they carry selected information of a ticket that is received via a mobile phone; reliable and secure personal identification, where they store personal biometric data on the identification document; and visual communications with side information, where they can be used as an auxiliary channel conveying additional data for improving visual communications.
