摘要

The method involves determining fingerprint of document (10) depending on measurement of value of physical unit of electronic chip (11) or medium (15) of document. The signature of control data and fingerprint are stored in chip. The signature of data is transmitted to verification server (12) so as to verify the authenticity of document. The signature stored in database of server is compared with predetermined signature. The document is considered to be authentic, if signatures match with each other. The document is considered to be altered or modified, if signatures are different. An independent claim is included for the system for securing electronic document.
