Abstract

The invention provides a bar code decoding device, which comprises a decoding unit and a verifying unit, wherein the decoding unit is used for decoding a bar code image by using a decoding program, and the decoding program comprises a program fragment; the verifying unit is used for receiving the program fragment, performing transformation on the program fragment and transmitting the transformed program fragment to the decoding unit; and the decoding unit continuously runs the decoding program by using the transformed program fragment to decode the bar code image. The device can ensure that adecoding process cannot be easily decoded and improve the security performance.

Description

【Technical field】 [0001] The invention relates to barcode technology, in particular to a barcode decoding device and a safety protection method thereof. 【Background technique】 [0002] Bar code technology is an emerging technology developed on the basis of computer technology and information technology that integrates coding, printing, identification, data collection and processing. Barcode technology is widely used in business, library management, warehousing, post and telecommunications, transportation and industrial control due to its advantages of fast, accurate, reliable and low cost, and is bound to play an important role in the emerging "Internet of Things" applications. role. [0003] Currently widely used barcodes include one-dimensional barcodes and two-dimensional barcodes. A one-dimensional barcode, also known as a linear barcode, is composed of multiple "bar" and "space" units arranged in parallel, and the barcode information is expressed by the different widt...
