Problems solved by technology

[0005] 1. Easy to counterfeit;
[0006] 2. The portability of the equipment is poor, printers and scanners cannot be carried around, and often cannot be found around the location;
[0007] 3. The timeliness is weak. Due to the second defect, many documents cannot be signed and sent back immediately
Most of the processing cores of specialized watermarking instruments are FPGA or ASIC, which have single functions and are not suitable for carrying around.
[0012] 3. Single type of watermark
Due to the existence of the above four defects, the scope of application of digital watermarking in daily commercial activities is limited, and it is more used in intellectual property anti-piracy and other aspects.

Embodiment Construction

[0053] The present invention provides a method for countersigning by using an intelligent terminal, including;

[0054] Receive the signature of the countersigner, add the signature to the document to be signed; make a digital watermark, add the digital watermark to the document through a preset algorithm, and send the document to the countersign recipient;

[0055] After receiving the file, the countersign receiver extracts the digital watermark from the file, compares it with the locally pre-stored countersigner watermark information, and outputs a countersign result.

[0056] Wherein, the document to be signed can be obtained locally, or sent to the countersigner by the other party who countersigns.

[0057] Wherein, the method further includes: collecting information required for making the digital watermark, and the information includes one or a combination of the following: password, signature handwriting, sound information, image information or a combination thereof.

Abstract

The invention provides a method for countersigning by using an intelligent terminal. The method comprises the following steps of: receiving a signature of a countersigner; adding the signature into a file to be countersigned; and making a digital watermark, adding the digital watermark into the file by using a preset algorithm, and sending the file to a countersignature receiving party. The invention also provides the intelligent terminal and a digital watermark receiving end. The countersignature is high in confidentiality, perfect in portability and strong in universality.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an intelligent terminal, a receiving terminal and a method for countersigning by using the intelligent terminal. Background technique [0002] After more than 20 years of development, terminals have become more and more powerful, and now they have developed into the stage of intelligent terminals. The functions of peripherals are getting stronger and stronger, the processing speed of chips is getting faster and faster, and the capacity of memory is getting bigger and bigger, which can realize many functions that were originally wanted but could not be realized. As a high-end smart terminal, its office assistance functions have been increasingly favored by business people. [0003] Transactions are frequent and often require signatures and seals. When the countersigner is on a business trip and cannot deal with it face to face, he can only send the document to be signed by ema...
