Problems solved by technology

However, when looking at many patents that have been published so far, such as encryption and decryption technology, digital certificates, asymmetric key digital signatures, etc., due to the complexity of the application procedures, it is inconvenient for ordinary people to use, so the relevant signatures and signatures are abandoned. Use of encryption and decryption functions

Embodiment Construction

[0037] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that in the following description, similar elements are denoted by the same numerals.

[0038] refer to figure 1 , the first preferred embodiment of the content verification method based on the digital signature code of the present invention is applicable to a server (not shown) with a database, including a signing step S1, a double signature step S2 and a verification step S3. The following uses a computer (not shown) that has been loaded with a terminal software program that realizes the present invention and the server with the database, and cooperates with the "Li Mushan dynamic business card" text file (file and the file described later, in the mainland language) Usually denoted as "file") to further explain the details of this method when performing "renewal". The dynamic business card is a (first) digital content, which contain...

Abstract

The invention discloses a method for verifying contents on the basis of digital signature codes. The method includes a signing step: signing a first digital content by the aid of a first private key to generate a first digital signature and a first signature code which correspond to the first digital content; a double-signature step: verifying the first digital signature according to the first signature code, and signing the first digital content again by the aid of a second private key according to the first signature code to generate a corresponding second digital signature and a corresponding second signature code; a verifying step: verifying at least one component of a digital signature group according to at least one component of a signature code group. The first signature code and the second signature code are connected with each other and form the signature code group, and the first digital signature and the second digital signature form the digital signature group. The method has the advantage that the authenticity of the signed digital content can be conveniently confirmed by the aid of the method.

Description

technical field [0001] The invention relates to a content verification method, in particular to a content verification method based on a digital signature code. Background technique [0002] Lianhe Daily reported on February 23, 2013 that the Ministry of the Interior stated: "The convenience stores currently cooperating with natural person certificate IC cards combined with convenience supermarket services include 4,791 unified supermarket stores that provide ibon services nationwide, and 2,830 nationwide that provide FamiPort services. Family Mart convenience stores, 1,252 Laierfu supermarkets across the country that provide life-ET and large-scale compound machine services, and 5 of the Circle K convenience stores in Taipei City.”. The news shows that the government actively guides natural persons to enter people's daily life with IC cards. However, when looking at many patents that have been published so far, such as encryption and decryption technology, digital certific...
