Abstract
The invention provides an electronic seal for an information medium signature containing an electronic component. The electronic seal comprises an information processing component and a reading/writing module. The information processing component comprises an encryption algorithm module and stores signature information and key information of the seal owner; the reading/writing module is connected with the information processing component and writes data into the electronic component and/or reads data from the electronic component; the encryption algorithm module performs encryption operation processing on the signature information by taking the key information as a password so as to obtain cipher text information; and the information processing component converts the cipher text information into the signature data written into the electronic component by the reading/writing module. Through the technology of the invention, the uniqueness and non-imitability of the signature information are improved based on the medium-based electronic bills so that the electronic bills are safer to use. With a method easy to identify and use, effective signatures of electronic bills are realized, the risk of using the electronic bills can be obviously reduced, and the development of modern financial industry is promoted.
Description
Technical field
The present invention relates to Electronic Signature, particularly relate to and pass to the Electronic Signature that the electronic unit that is embedded in the medium such as radio electronic label are used for bill identification after stamped signature information encrypted the information medium signature that comprises electronic unit.
Background technology
Along with the development of modern economy, the health of financial circles, orderly, safe development are significant for current economic development.In the financial circles development, popularize to the comprehensive of various financial documents gradually from money transaction, become the main means of payment that miscellaneous service is carried out in the modern economy like the letter of credit, cashier's cheque, check etc.
But because the value of financial document itself and circulation receive very big challenge for the security of financial document.Report is arranged when forging case that the letter of credit, cashier's cheque, check carry out financial swindling all over the world.And owing to the circulation of the letter of credit, cashier's cheque, check can repeatedly be transferred the possession of, and wherein any once transfer appearance forgery all possibly bring massive losses to the related side.
With regard to the antifalsification of the present employed letter of credit, cashier's cheque, check normally based on some anti-false signs on concession manufacturing and the ticket; The validation of the letter of credit, cashier's cheque, check is based on the person's that provides the bill signature or endorsement.And based on the reason of cost with technology, the anti-false sign of the letter of credit, cashier's cheque, check is also uncomplicated, is easy to by the fake producer imitated.And there are two problems in the signature or the endorsement that are used for the validation of the letter of credit, cashier's cheque, check: be that signature or the endorsement that same individual carries out in decentraction situation attitude, different time points can not guarantee in full accord on the one hand; Cause effective signature or endorsement to be rejected acceptance; Be because signature that requires to carry out or endorsement must be basic identical at every turn on the other hand, for the fake producer provides the chance of faking.Signer or endorsement person's signature or endorsement information is no matter how unique, in case seen signature or endorsement information by illegal person, the exercise through certain hour can realize the imitation for signature or endorsement information fully.And be to compare by human eye to judge for the validation of the letter of credit, cashier's cheque, check now.The safety technique that obvious existing ticket adopted can not provide safeguard for the Secure Transaction function that realizes bill.
Use the replacement signature that carves a seal for many years in China, though guaranteed the consistance of each signature, owing to carve a seal too easily by imitated, so and dangerous.Even through the administrative intervention of government, take the administrative authorization mode to specify and have only professional could carry out the business of carving a seal, but can not stop illegal person's imitated behavior owing to the technical not high of itself through authorizing.
Though extensively popularizing of the development of modern network technology and internet is for the development of financial circles brings new opportunity.Like Internet-based banking services and for the electronic key authentication techniques that guarantee Internet-based banking services safety are just becoming the important directions that modern finance already develops, but the safety that also greatly threatening Web bank such as network hacker, virus, fishing program simultaneously.Be still the major transaction instrument of modern finance industry based on the business transaction of financial document.
Summary of the invention
Technical matters to be solved by this invention is how to strengthen the safety of electronic bill and how to guarantee the signing messages of electronic bill and/or the security and the validity of endorsement information; And realize effective circulation of electronic bill with the mode of a kind of easy identification and use; To reduce the risk in the electronic bill use, promote the development of modern finance industry.
