Abstract

The invention discloses a security encryption method and system for a personal electronic signature. The method comprises the steps that an electronic signature producer applies for a digital certificate; the applicant writes a signature and stores the signature as a picture; anti-counterfeiting processing is performed on the handwritten signature picture by using a digital watermark; an abstractvalue of the handwritten signature picture, the column number and the seal maker certificate is generated by using an SHA1 algorithm; the abstract value is encrypted by using a private key; and a result is returned after encryption to finish encryption. The digital watermarking technology is used, copying and tampering are prevented, and it is ensured that the seal is unique; digital signature andverification operation are realized by using an asymmetric algorithm ECC and a hash algorithm SHA1, and the security, confidentiality and tamper resistance of the electronic signature are higher.

Description

technical field [0001] The invention relates to the technical field of electronic encryption, in particular to a method and system for secure encryption of personal electronic signatures. Background technique [0002] An electronic signature is not a digital representation of a written signature. It's actually an electronic code that allows recipients to easily verify the sender's identity and signature online. Electronic signature is a general term for modern authentication technology. It is the data in electronic form contained in, attached to, or logically associated with a certain data message. It can be used to verify the signer related to this data message. identity and indicate that the signatory approves the information contained in the data message. Moreover, electronic signatures can also be used to verify whether the original text of the document has changed during transmission. [0003] Although the country has relevant regulations on electronic signatures, it...
