This thesis investigates the use of Digital Signatures based on Digital Certificates to enhance document security and combat forgery and tampering. Emphasizing their role in strengthening existing signing systems, the study explores the implementation of a QR code integrated with a digital signature using the Reed Solomon Correction Method, which ensures accurate scanning even with partial damage. The framework enables the creation of legally binding, reliable, and verifiable electronic documents. Performance evaluation was conducted using JMeter, and the system achieved prediction accuracies ranging from 65 to 98 out of 100, with an overall accuracy of 97%. The findings confirm the reliability, portability, and minimal repudiation of the proposed system, while also highlighting the importance of a scanning verification mechanism to foster user trust. The study identifies current limitations, particularly the need to expand the dataset and quantitative variables, and provides a solid foundation for future improvements and research in digital signing systems.
