The digital camera (recorder) of (310) immediately acquires the generated digital content file (15). The attribute generating unit (520) is configured to generate terminal information (410) corresponding to the digital content file (15), and the terminal information (410) includes user information (411) of the digital content file (15) and digital terminal device location identification. Information (412). The compression encryption unit (530) is configured to generate a file key (151) by performing a compression encryption process on the digital content file (15). The data transceiver unit (541) is configured to drive the digital terminal device (310) to transmit the file key (151) and the terminal information (410) to the outside, and drive the digital terminal device (310) to receive a voucher identification code from the outside (162). ). The voucher identification code (162) is compiled and generated by a voucher file (16), and the voucher file is generated. (16) comprising an archive key (151), terminal information (410) and an external time information (420) and external cloud storage information (430), and the voucher identification code (162) may be externally an optical reader Read the contents of the voucher file (16).

The digital certificate storage medium (501) is used in a digital terminal device (310) of the digital content integrated certificate storage device (300) for depositing a digital content file (15). The digital content integrated storage device (300), as shown in FIG. 1, includes a plurality of digital terminal devices (310), at least one digital certificate server (320), and a digital terminal device (310) and a digital certificate server. The network device (390) of the device (320). The entire depositing step can be illustrated by the following steps:

(a) A digital content file (15) is provided at the digital terminal device (310).

(b) The terminal information (410) corresponding to the digital content file (15) is generated at the digital terminal device (310).

(c) The digital content file (15) is generated by the digital terminal device (310) by compressing the encryption program to generate an archive key (151).

(d) The file key (151) and the terminal information (410) are transmitted to the digital certificate server (320) via the network device (390).

(e) The digital certificate server (320) generates time information (420) corresponding to the file key (151) and cloud storage information (430), and the time information (420) is received by the digital certificate server (320). The time after the file key (151) includes the first time information (421) and/or the second time information (422), and the first time information (421) is the local time of the digital certificate server (320). The second time information (422) is the time provided by the third party other than the digital terminal device (310) and the digital certificate server (320) to the digital certificate server (320); the cloud storage information (430) is the digit The deposit server (320) remarks the information loaded on the archive key (151) according to a preset rule.

(h) The credential identification code (162) is transmitted to the digital terminal device (310) via the network device (390).

In Figure 2, the compression encryption program of the compression encryption unit (530) compresses and encrypts the digital content file (15) to generate a unique corresponding file key (151). In particular, as long as the content of the digital content file (15) is different, the content of the file key (151) will not be the same, and the same digital content file (15), no matter how long, the compression encryption generated. The file key (151) will always be the same. In one embodiment, the archive key (151) refers to the encoded data generated by compression and encryption of the digital content file (15) by a hash algorithm. The file size of the encoded data is much smaller than the file size of the digital content file (15). For example, the MD5 algorithm is used to perform file key (151) compression and encryption on the digital content file (15), and the obtained file key (151) is obtained. It is 128-bit information. Thereby, the time for uploading the 128-bit file key (151) to the digital certificate server (320) through the network device (390) is much shorter than the time for directly uploading the digital content file (15), thereby solving the problem.

In addition, by using a hash algorithm such as MD5, an archive key (151) uniquely corresponding to the digital content file (15) can be obtained, thereby further demonstrating the uniqueness of the digital content file (15). That is to say, if there is any modification of the digital content file (15), the file key (151) obtained by the hash algorithm for the digital content file (15) compression and encryption generation will change, that is, before the modification. The digital content file (15) compresses the encrypted generated file key (151) differently from the modified digital content file (15) and compresses the encrypted generated file key (151). And the digital content file (15) is compressed and encrypted to generate the file key (151) is a non-reversible program, and the content of the digital content file (15) cannot be reversed by the file key (151) through any restoration project, thereby ensuring the digital content. The file (15) will not leak. It should be noted that the file key (151) compression and encryption generation using the MD5 algorithm is only one embodiment of the present invention. In addition to the MD5 algorithm, MD4, SHA-1, SHA-225, and SHA-256 may also be used. Hash algorithms such as SHA-384 and SHA-512 are used to generate the archive key (151).

The first time information (421) is the local time at which the digital certificate server (320) receives the uploaded file key (151) and can be used to prove the existence time of the file key (151). Since the archive key (151) is uniquely corresponding to the digital content file (15), the time information (420) can prove the fact that the digital content file (15) uniquely corresponding to the uploaded archive key (151) exists at a specific time. .

The second time information (422) may be provided to the digital certificate server (320) by a third party other than the digital terminal device (310) and the digital certificate server (320). For example, the digital certificate server (320) can establish a connection with a state-authorized time verification authority or other organization that can provide standard time (eg, Greenwich Mean Time, Central Plains Standard Time), and is stored in a digital location by a mechanism that provides standard time. Certificate server (320) provides standards The time information (420) or the time correction of the digital certificate server (320) makes the time information (420) more accurate and more reliable.

In a derivative embodiment of the first embodiment and the second embodiment, the data transceiving unit (541, 542) further drives the digital terminal device (310) to externally transmit the digital content file (15) to the digital certificate server. (320). The main purpose is based on the consideration of cloud storage.
