Detailed Description
The embodiment of the invention provides a video storage method, a video storage device, video storage equipment and a video storage medium.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be implemented in other sequences than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," or "having," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For understanding, a specific flow of an embodiment of the present invention is described below, and referring to fig. 1, an embodiment of a video storage method according to an embodiment of the present invention includes:
101. receiving a video storage instruction, reading a video address in the video storage instruction, and accessing the video address to capture a target video;
in the embodiment, the video saving instruction band also has a video address URL, and the target video to be saved is captured from the video address URL by accessing, which is common in wechat, web pages and mailboxes.
Further, the following steps may be performed in the step of "accessing the video address to capture the target video":
1011. accessing the address of the video to construct C + + std: : the offset object reads the target video.
In the embodiment, the C + + std means that the offset object is a pointing operation of a C + + file read-write operation and is realized in a nested manner. The manner in which the function is constructed may be performed as follows:
ofastream (); // default constructor
explicitofstream(constchar*filename,ios_base::openmodemode＝ios_base::out )；
explicit stream (constraining & filename, ios _ base:: o ut); the first parameter filename is the location of the file to be read, and the second parameter mode describes the i/o mode flag of the file request, i.e., the way the file is opened.
Based on C + + std: : and obtaining the target video by the offstream object.
102. Reading a user ID corresponding to the video storage instruction, and judging whether the user ID belongs to a storage permission ID;
in this embodiment, the video saving command may include a user ID, or may include a character pointing to the user ID. After the user ID is obtained, it is checked on the Internet whether the user ID belongs to the storage permission ID.
Further, in "judging whether the user ID belongs to the storage license ID" the following manner may be performed:
1021. sending the verification request of the user ID to a preset server address;
1022. and receiving a verification result fed back by the server address, and judging whether the verification result is a storage permission result.
In steps 1021-1022, the internet queries the user ID, first sends the authentication request of the user ID to the preset server address, the server receives the user ID query request, analyzes the account number of the user ID, determines whether to purchase the related service, returns the authentication result of the storage permission if the related service is purchased, but returns the authentication result of the non-permission if the related service is not purchased, and the application program processes the video according to the returned authentication result.
103. If the target video does not belong to the storage permission ID, reading the first N characters of the target video, and encrypting the first N characters to obtain N encrypted characters, wherein N is a positive integer;
in this embodiment, when the user ID does not belong to the storage permission ID, the first 100 characters of the target video are encrypted, and the encryption method of the first 100 characters may use encryption algorithms such as AES, RC4, DES, 3DES, RC5, and RC6, but a new 100 encrypted characters are obtained at last, where the number of the encrypted characters must be consistent with the number of characters read by the target video, because the user stores the encrypted video and reviews the encrypted video with the application program, the encrypted video needs to be decrypted for the user experience, and the application program is used to review the encrypted video.
Further, the following steps may be performed during the "reading the first N characters of the target video":
1031. by the C + + std: : reading () function of the ofstream object, reading the first N characters of the target video, and storing the first N characters into an encorptData array.
In this example, C + + std: : the stream object is attached with a read () function, so that the first 100 characters of a target video can be directly viewed, the 100 characters are written into an encorptData array, and the encryptData array is used as encrypted data and is not easy to crack by the outside.
Further, the following steps may be performed to "encrypt the first N characters to obtain N encrypted characters":
1032. and performing AES256 encryption processing on the encorptData array according to a preset encryption key to obtain N encrypted characters.
In this embodiment, the encryption key is preset, and 100 encrypted characters are generated by performing encryption processing of the AES256 algorithm on the encorptData array through the encryption key.
104. And replacing the first N characters of the target video with the N encrypted characters to generate an encrypted video, and storing the encrypted video according to the video storage instruction.
In this embodiment, 100 original characters of the target video are replaced, 100 encrypted characters are replaced by 100 original characters, so that an encrypted video can be generated, and then the encrypted video is stored based on a video storage instruction, so that video encryption storage meeting commercial requirements is realized.
Further, after 104, the following steps may also be performed:
105. receiving a video viewing instruction sent by the user ID;
106. and reading the encrypted video corresponding to the video viewing instruction, and decrypting the first N encrypted characters of the encrypted video to obtain the viewing video.
In steps 105-106, after the encrypted storage is realized, in order to improve the user experience, the user needs to view the encrypted video through the business program software, and the scheme is mainly for realizing the service business and avoiding that the user obtains the specially-effective video without paying, so that the user executes the re-decryption on the video viewing instruction after the storage is finished to generate the viewing video.
Further, at 106, the following steps may be performed:
1061. reading the first N encrypted characters of the encrypted video, and storing the N encrypted characters in a decData array;
1062. according to a preset encryption key, carrying out AES256 decryption processing on the decData array to obtain N characters;
1063. and replacing the first N encrypted characters in the encrypted video by the N characters to obtain a viewing video.
In steps 1061-1063, the process is also based on C + + std: : the ofstream object reads the first 100 encrypted characters of the encrypted video because there is no need to perform encryption again but decryption stores the 100 encrypted characters in the decData array. Based on the same encryption key during encryption, the decData array is subjected to AES256 decryption processing to obtain 100 characters. And replacing the first 100 encrypted characters in the encrypted video by the obtained 100 characters to obtain the viewed video. Where viewing the video is that the user has not previously paid for storage of the video stored locally, the encrypted video is re-decrypted for use by the user in order for the user to continue to modify and effect commercial purchases.
In the embodiment of the invention, in order to reduce the performance consumption of encryption and decryption, the encryption and decryption are only carried out on the small area of the video head part, so that the effect that the video cannot be played is achieved, and the requirement of commercial protection is met. Meanwhile, the encryption range is accurate to the video head, so that the resource consumption in the encryption process is reduced, the use experience of a user is improved, and the defects of the prior art are overcome.
