Tamper detection of electronic bills based on semi-fragile Watermarking
With more and more applications and developments of financial information in the world, electronic bills become more and more important in the financial industry due to its low costs and high efficiency. While in the implementation of electronic bill, there exist many problems relating to integrity guarantee and modification prevention. This paper introduces a method of electronic bills against modification based on watermarking technology. Applying semi-fragile watermarking to protect electronic bills, the bills can withhold some reasonable minor modifications, such as moderate image compressing and color-to-grey conversion without warning information. While if these electronic bills are tampered deliberately, these modified bills can be identified and warning information is prompted when detecting watermark.
