Digital authentication control medium and digital terminal device having network communication function

Abstract

A digital authentication control medium comprises: a digital capturing unit for capturing a digital content file; an attribute generating unit for generating terminal information corresponding to the digital content file, wherein the terminal information comprises user information of the digital content file and digital terminal device position identifying information; an encripting unit for generating a file secret key by performing an encripting program to the digital content file; and a data transceiving unit for driving the digital terminal device to transmit the file secret key and the terminal information outwards, and driving the digital terminal device to receive a certification identification code from the outside, wherein the certification identification code is generated by compiling of a certification file, the certification file comprises the file secret key, the terminal information, external time information and external cloud storage information, and content of the certification file in the certification identification code can be read by an external optical reader.

Description

【Technical field】 [0001] The invention relates to digital data transmission and preservation technology, in particular to a digital storage control medium. 【Background technique】 [0002] Nowadays, digital content archives are used in more and more fields, but because they are easily tampered and forged, people cannot identify their existence time, authenticity and reliability. In the fields of digital copyright protection and intellectual property protection, how to prove the originality and timeliness of digital content files is a serious issue that must be faced. [0003] The current common way to protect digital content files is to upload the complete digital content files to the server, then encrypt the digital content files through the server and record the upload time at the same time to prove the originality and timeliness of the digital content files. [0004] However, the above-mentioned application needs to upload the original digital content file to the server. ...
