Problems solved by technology

However, digital signatures are not fast and intuitive enough in the application of document signing, because in daily life, handwritten signatures are often used on paper to indicate that the document has been reviewed and signed, so it is easier for people to accept handwritten signatures in the form of document signing
[0003] In summary, the existing digital signature technology obviously has inconvenience and defects in actual use, so it is necessary to improve it

Abstract

The invention, which is suitable for the communication technology field, provides a method for generation of a hand-written signature by utilizing a fingerprint. The method comprises the following step: a hand-written signature storage step, that is, storing at least one hand-written signature in advance; a digital signature step, that is, using a fingerprint feature of a user as a private key to carry out digital signing on an electronic document and using an asymmetric encryption algorithm to generate a public key; and a hand-written signature implantation step, that is, implanting the hand-written signature to a predetermined position of the electronic document. Correspondedly, the invention also provides a communication terminal. Therefore, according to the invention, signing work of electronic documents can be carried out rapidly, clearly and visually; and moreover, the signing work is in line with users' habits.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for generating a handwritten signature by using a fingerprint and a communication terminal. Background technique [0002] Digital signature technology is mainly used in the field of encryption and data transmission. It is an application method of encrypting with a private key and decrypting with a public key in asymmetric encryption. The application process of digital signature is: the data source sender uses its own private key to encrypt the data checksum or other variables related to the data content to complete the legal signature of the data, and the data receiver uses the other party's public key to Interpret the received digital signature, and use the interpretation result to verify the integrity of the data to confirm the legality and authenticity of the signature. However, digital signatures are not fast and intuitive enough in the application of document...
