Electronic signature gets rid of the shackles of time and space of paper signature, which can greatly improve work efficiency, save time, and improve the transparency of office management, which is of great benefit to enterprises. In order to establish the legal effect of electronic signature, the state has also adopted the electronic signature law and other legal protection system. This is the guarantee of the security of the electronic signature at the legal level, so how does the electronic signature protect the personal interests of the users at the technical level?

With the heating up of the construction industry, designers have to face a lot of design work every day. Compared with the tedious drawings, they are more worried about the hard-working drawings being tampered with, so they need to confirm the ownership of the drawings. Electronic signatures can well protect the work of designers. Pengyucheng CAD electronic signature software-DWG interactive electronic signature tool uses electronic signature technology to replace the designer's handwritten signature, which can effectively verify the identity of the drawing, because the handwritten signature or the signature inserted into the picture can be easily modified, and the electronic signature indicates the ownership of the drawing on the one hand, and more importantly, when the drawing is edited or tampered with by others, the name signed by the designer will be invalid automatically. So as to ensure the attribution of the responsibility of DWG documents. After the drawings are designed, they need to be approved, transferred and delivered. In this process, the authenticity, reliability, and non-repudiation of the original works are basically guaranteed.

On the technical level, the protection of the interests of users by electronic signature is reflected in the encryption technology it uses. The electronic signature applies the PKI digital security authentication system, which bundles the digital certificate with the electronic signature. When signing, the digital certificate can be added automatically, and the document can be signed and sealed to ensure the authenticity and credibility of the document source. In addition, the electronic signature can also provide the identity authentication of the signer, that is, encrypt / decrypt the certificate public key and the corresponding private key, and generate the signature and verification signature of the electronic drawing file. The digital signature technology combined with electronic signature uses public key cryptography and other cryptographic algorithms to generate a series of symbols and codes to form electronic ciphers to sign instead of writing signatures and seals. the accuracy of its verification is incomparable to that of manual signatures and seals in the physical world. Therefore, no matter in the legal system or technical guarantee, electronic signature, as a new security technology to gradually replace handwritten signature in the future office environment, needs to play a greater role for enterprises and individual users.

The technology of electronic signature is very complex, but it is very convenient to use. At present, Pengyucheng's electronic signature supports the signature of DWG drawings, Office series software and pdf documents. Users can implement electronic signatures inside these format files in the normal way of editing documents. First of all, we should collect the handwritten signature picture of the signer, and use the signature making tool to make everyone's electronic signature file, that is, the signature sample file. Signature samples can be stored in two ways, one is stored on disk, the other is stored on smart card (smart card verification). The signature of the file can be realized by calling out the target file and adjusting the size and location of the inserted signature. Peng Yucheng's electronic signature software is available for users to download free of charge, and users in need can download and try it out.
