Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the present invention proposes an electronic signature anti-tampering system comprising:

[0022] PDDL conversion device, used for data conversion of acceptance form data into PDDL data;

[0023] The picture generation device is used to generate the acceptance sheet picture according to the PDDL data;

[0024] A signature recognition device for recognizing the user's handwritten signature;

[0025] The PDF conversion device is used to convert the picture of the receipt signed by the user into a PDF file.

[0026] The picture generating device is used for parsing PDDL data; judging whether there is a global setting, if yes, setting the global, and performing the next judgment, if not, directly executing the next judgment; judging whether there is a block data setting, if yes, executing the next step One-step judgment, if no, gener...

Abstract

The invention discloses a tamper-resistant system for an electronic signature. The tamper-resistant system for the electronic signature comprises a planning domain definition language (PDDL) conversion device, a picture generation device, a signature identification device and a portable document format (PDF) conversion device, wherein the PDDL conversion device is used for converting acceptance form data into the PDDL data; the picture generation device is used for generating an acceptance form picture according to the PDDL data; the signature identification device is used for identifying a handwritten signature of a user; and the PDF conversion device is used for converting the acceptance form picture which is signed by handwriting by the user into a PDF file. By defining a PDDL data protocol, supporting the generation of a general acceptance form data picture, and directly signing on the picture by handwriting, what you see is what you get, the signature is synthesized directly without storing signature data, so that the security of the signature is improved; paperless office and electronic data management are realized; and the aims of saving energy and reducing emission are fulfilled.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an electronic signature anti-tampering system. Background technique [0002] The handwritten signature required for business acceptance based on the smart terminal platform should be applied to the handwritten signature on the business acceptance form to complete the confirmation of business acceptance. Existing technologies generally use peripherals to provide support and are applied to non-smart terminal platforms, and none of them are handwritten signatures based on smart terminal platforms. Correspondingly mentioned peripherals or both require device support. [0003] For example, the Chinese patent application with the application number CN201110255294 and the title of invention "a pressure-sensitive handwriting display screen" discloses a pressure-sensitive handwriting display screen, which includes a flat panel display, a tablet and a stylus. The flat panel display i...
