1, the traditional paper signature is directly signed with a pen, while the online electronic signature needs to be completed on a third-party electronic platform. Signing an electronic signature on an electronic file is to encrypt the electronic file and its message digest data with a private key. There are many ways, such as automatic signature, click signature, SMS signature, video signature and so on.

2. Traditional paper signature is only verified by visual comparison and recognition of handwritten signature information, so as to confirm the authenticity of its signature. However, it is undeniable that online electronic signature verification is done on the Internet. The verifier owns or can directly access the digital certificate (including public key) of the electronic signer to verify the authenticity of the signature in the electronic file and the identity of the signer.

3. Traditional paper signatures are only handwritten characters when signing, while online electronic signatures are generally graphics or images, that is, graphics or seal images composed of handwritten signature characters with personal characteristics (but the effectiveness of electronic signatures is not based on the graphics or images themselves, but on the digital certificates behind them).

At present, online electronic signature is the product of the development of e-commerce, and its appearance has posed a strong challenge to the traditional signature method. Moreover, online electronic signatures have the same legal effect as paper signatures, and enterprises can rest assured that digital certificates of third-party electronic platforms are legal protection when using them.
