Mixed electronic bill

Abstract

The invention provides a mixed electronic bill and in particular relates to an electronic bill which is characterized by printing encrypted signature information on an information medium, electronizing the encrypted signature information on electronic paper and transferring the encrypted signature information to an electronic component embedded in the medium and is used for bill authentication. At least an area of the information medium comprises electronic paper. A first specific signature area is set at the obverse side and / or reverse side of the information medium and a second specific signature area is set at the obverse side and / or reverse side of the electronic paper, and ciphertext information obtained by encrypting the signature information is printed in the first specific signature area and / or the ciphertext information obtained by encrypting the signature information is presented in the second specific signature area by electronizing. By adopting the technology of the invention, on the basis of the electronic bill based on the medium, the uniqueness and the non-imitability of the signature information are improved, thus ensuring the electronic bill to be used more safely. Valid signature of the electronic bill is realized by adopting a way which is easy to identify and use, thus obviously reducing the risks in using the electronic bill and promoting the development of the modern financial industry.
