FIELD: electricity; information technology.
SUBSTANCE: invention relates to electronic industry, namely, to data technologies of document management. Device for signature of documents is made in the form of stylus and comprises a protective compartment, where there is a microcontroller with a program code, memory with a secret key of the digital signature and additional inertial sensors, connected to the microcontroller, a lens system and camera, also connected to the microcontroller. Wireless interface is used for connection to the computer. Inertial sensors serve to check handwritten signature of the user, lens and camera are used to compare it with a text of the electronic document, loaded through the wireless interface. Trusted environment is formed in the signature device and any not certified computer may be used.
EFFECT: safe input of electronic document from any computer in the signature device.
