Method for mobile electronic signature

Abstract

The invention discloses a method for a mobile electronic signature. The method comprises the following steps that: a server sends a short message requesting an approval signature to a terminal; the terminal receives the approval signature short message and displays the content of the approval signature short message on a display screen; the terminal receives the approving content inputted by an approver; the terminal reads the data of the characteristic factor of the terminal, and works out the first encrypted data by taking the data and the approving content as variables of an encryption algorithm; the terminal answers and sends the first encrypted data and the approving content to the server; the server receives the first encrypted data and the approving content; the server reads the stored data of the characteristic factor, and works out the second encrypted data by taking the data and the approving content as variables of the encryption algorithm; and whether the first encrypted data and the second encrypted data are the same is judged, if so, the approval signature is confirmed and stored, otherwise the signature is the unapproved signature and neglected. The method has the advantages that the signature approver can give particular written instructions or assessments and examine the correctness of the approving content according to the content to be approved.

Description

Technical field [0001] The invention relates to a method for moving an electronic signature. Background technique [0002] Existing electronic signature methods, such as the patent application for invention titled "Electronic Signature Mobile Terminal, System and Method" published by China Patent Bank on June 13, 2007, its patent number is CN200510124291.6. Although this invention patent application can realize electronic approval signature, it has the following shortcomings: 1. The approval signer can only choose to agree or disagree, and cannot give specific instructions based on the content of the approval, such as revision opinions, etc. This brings great inconvenience to the approval process and increases the number of approval processes; 2. A third party is introduced in the approval and signature process, which makes the approval and signature process complicated, requires high costs, and increases the possibility of leaks; 3. The scheme is accessed through the STK pr...
