Can you be more specific? As far as I know, the stamp on e-sign is safe and legal, because e-sign, like cloud contract, is an authoritative third-party electronic contract signing platform, and it is not stamped at will. Electronic signature is a form of electronic signature. Image processing technology is used to transform the electronic signature operation into the same visual effect as the stamping operation of paper documents, and electronic signature technology is used to ensure the authenticity and integrity of electronic information and the undeniable nature of the signer.

In fact, the electronic signature itself is not a "signature", but an asymmetric public key security system, and its operation mode is essentially a mathematical operation. Therefore, electronic signature is not only an electronic picture of traditional official seal, but also an electronic signature technology. Common electronic signature methods on the Internet, such as taking photos, scanning or using graphic software to generate electronic signatures, cannot guarantee the legal effect of electronic signatures.

Using the third-party electronic signature platform for production is faster and more efficient.

After the third-party electronic signature platform authenticates the applicant's real name, it applies to the third-party CA organization to issue a CA certificate, and then generates a valid electronic signature. This method is not only simple, but also effective and legally binding.
