The Design Of Enterprises' Seal Comparison System

Since the protection of information,seals have a long history as a means of proving the validity of documents in daily life.Seals are widely used for their simplicity,practicality,reuse,and ease of storage.With the rapid development of science and technology,the exchanges between various industries have become intricate,and the imitation seals are difficult to distinguish with the rise of technology.The traditional manual method is inefficient and has high false positive rate and low accuracy.The details are unrecognizable to the naked eye,and the results are limited by many factors and cannot meet the actual work requirements.Therefore,it is urgent to improve the recognition efficiency of seals,and the comparison of seals is an important task in distinguishing the authenticity of seals.The paper first introduces the principle of color model conversion,as the basis of image recognition,and then introduces the method of seal extraction and registration.Based on the above theory,this paper develops a seal comparison system.By uploading the image to be tested,the image of the proof to be tested is converted into HSI color model,and the corresponding image is extracted by FAST algorithm.The registered signature image is compared with the standard pattern to give the similarity of the seal pattern.The whole system is developed by using SpringBoot framework,which is mainly divided into administrator module and printer module.The administrator is responsible for entering the standard seal,and the printer uses the system to make the seal comparison.The system realizes the storage and management of the seal image,and strengthens the ability to identify the anti-counterfeiting in the seal comparison,thus effectively avoiding the entry and modification problems brought by the manual management and proving its practical value.The paper demonstrates that the method can correctly extract and compare the seal images through software test methods,which effectively reduces many unfavorable factors caused by manual comparison in the seal comparison process and improves the accuracy of seal identification.However,the seal used in the experiment is more regular.The next step is to identify and optimize the irregular seal or part of the defective seal,and improve the scope of the system in the seal identification.
